摘要： 450,405. Liquid - blast switches. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, LEESON, B. H., Waverley, Tynemouth, and WILD, R. W., 33, Oakwood Avenue, Harlow Green, Low Fell, Co. Durham. Jan. 16, 1935, No. 1452. [Class 38 (v)] In liquid-insulated A.C. circuitbreakers of the kind in which the movable contact is drawn through an enclosure in an arc control device in which a relatively high pressure is produced by the arc so that the compressed liquid, vapour, and gas in the enclosure constitutes a deionizing fluid or blast which forces the ionized arc gases through vents in the enclosure which are laterally disposed with respect to the arc path, the part of the enclosure-wall in the vicinity of the vents (or some of them) is formed in one or more parts separate, and readily removable, from the rest of the structure. The enclosure A is formed in a cylindrical moulded insulating block A, in the side of which are formed a series of apertures A of rectangular section which are tapered at A to receive the removable vent members C of fibre or other insulating material having grooves C constituting the vents. A separate throat member D of fibre or other insulating material has a series of holes D' constituting the vent throats, and is removably received in a groove formed in the block A and by projections C on the members C. The vents C may all be radially directed from the axis of the movable contact B, or, as shown, may be offset, in which case they are preferably alternately oppositely directed, so that the reactive forces on the structure are partly eliminated, and in double-break switches a better distribution of arc products in the ambient liquid is obtained. The block A is mounted in an outer tube E of, for example, varnished paper which is provided with lateral outlets E or a continuous slot or slots for the blast. The upper end carries one element E of a bayonet joint, the other F of which is supported by the bushing F, and a latch E retains the parts in place. The movable contact B enters the enclosure through a throat washer G loosely mounted between a ring E and end plates E . Instead of the rod contact B shown, a flat bar with rounded edges may be employed, and in either case a renewable tip may be fitted. Magnetic means as disclosed in Specifications 435,250 and 435,308 may be employed to deflect the arc into, and seal, the throats D , the means shown comprising laminµ H of magnetic material embedded or moulded in the block A. Since the remaining vents are also substantially closed by contact B, a high pressure is set up by the arc when it is formed in the enclosure A , which pressure acts at the non-arcing period, that is, the zero of the cycle, to force the gases and fluid through the open vents. By varying the size of the vents or their number, as by providing plates C without vents, a single size of block and main structure may be added to a range of switchratings. Pockets for retaining liquid near the arc may be provided in the form of grooves in the enclosure-wall, one diametrically opposite each vent. Fig. 7 shows a modified structure comprising side members J, J and baffles J supported in J, J by means of their edges J so that inwardly tapering spaces C constitute the vents. The outer faces have keyways J , J co-operating with keys in the block, which is cut away at one side snugly to receive the structure which narrows towards the periphery so as to resist outward movement due to the arc-pressure. The vent structure can alternatively be moulded in a single block. In Figs. 9, 10, the block is made up of alternately arranged circular plates and plates L having cut-away parts to receive the vent members C. Fig. 10 shows a form of removable oil-retaining member M, having oil pockets M cut in a block of fibre or mouldable insulation, and defining with the throat-member D an arcing enclosure. Such a member M can be fitted to the other forms shown. The lateral outlets in the casing E may in all forms be replaced by a longitudinal passage discharging at the top and/or bottom of the structure, a suitable passage being formed by cutting the side of the block flat near the vents. The uppermost vent may be set back a little so as to reduce the pressure in the enclosure when closing the breaker, or alternatively the seep hole F may be made sufficiently large for this purpose. The main block A may be of fibre, in which case the enclosure A may be machined, vent members may be dispensed with by drilling vents in the block, and a groove may be cut to receive the removable throat member. Other materials for the block and vent and throat members are products having an asbestos base, as sindanyo, vitreous materials, as porcelain, and natural insulating materials as slate or a hardwood. The block may be alternatively of a phenol-formaldehyde or thio-urea product, such as the substances known under the Registered Trade Marks "Bakelite" and " Beetle." Specification 366,998 also is referred to. The Provisional Specification states also that, where baffle plates are employed, they may be resiliently clamped together to relieve excess pressures, for example, where the clamping is by means of longitudinal bolts, the latter may have spring washers.

摘要： 391,134. Protective cutout arrangements. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, CLOTHIER, H. W., 3, Jesmond Park. West, Newcastle-on-Tyne, LEESON, B. H., Waverley, Tynemouth, and LEBEN, H., 8, Queen's Walk, Harrow, Middlesex. Oct. 15, 1931, No. 28725. [Class 38 (v).] In a sectionalized power circuit each section is protected independently of the other sections by means of a tripping relay device at each end, the arrangement being such that the tripping of the circuitbreaker at each end is controlled jointly by the operation of the adjacent tripping relay device, and the operation of the tripping relay device at the other end, means being also provided to prevent tripping of the circuit-breakers at both ends when power is flowing into the section at one end, and out at the other. In the arrangement shown in Fig. 3, with a fault in the section A, current flows into the section at both ends, and non-directional tripping relays D , d at the ends operate. These relays D , d are such as described in Specification 391,135, and operate first to close their contacts D , d and then to close their contacts D . d . Stabilizing directional relays C, c are also provided at each end as described in Specification 314,778, [Class 38 (v), Electric switches &c.], and with a fault such as that being considered, these relays remain inoperative. Closure of the contacts D , d , of the relays D , d , therefore produces no effect, but when the contacts D , d are closed, relays E, e are operated to connect batteries J , j , in series in the pilot wire circuit H , H , so that current flows in such a direction that polarized relays F , f operate, but polarized relays G , g remain inoperative. The contacts E , e of the relays E, e having been closed, and the contacts F , f of the relays F , f closing in response to the energization of the relays, the circuits of the tripping coils B , b of the circuit breakers B, b are completed, and the section A is isolated. With a fault external to the section causing a heavy current to pass from the home end B to the remote end b of the section, the relays D , d , c operate. Closure of the contacts d causes, through contacts c of the relay c, energization of a relay l at the remote end. This relay disconnects the battery j and connects a battery k of higher but opposite potential to the circuit of the pilot wires H , H , which circuit is completed by relays e, E energized by the contacts d , D of the relays d , D . The batteries k, j are now connected in opposition in the pilot wire circuit, and current flows in such a direction that polarized relays G , g operate to open the tripping coil circuits of the circuit-breakers, and prevent isolation of the section. If there is a fault in the section A fed only from the home end B, the relay D only operates to energize the relay E, and after a time interval contacts E are closed to complete the tripping circuit of the circuit-breaker B independently of the contacts F . Simplified arrangements in which the tripping relays D, d are directional, and in which three or four pilot wires are necessary, are described with reference to Figs. 1 and 2 (not shown). In Fig. 4 (not shown), pilot wires are dispensed with, and the relays F , G , f , g are replaced by non-polarized relays which receive currents of different frequencies transmitted over different lines of the main system by transmitters at the remote end controlled by the operation of the relays D , d , C, c. The arrangement shown in Fig. 3 can be adapted to an arrangement in which four pilot wires are used, the relays F2, G2, f , g being non-polarized, and only one battery being required at each end. The pilot wires may be borrowed from telephone or similar circuits. Fig. 6 shows the manner in which the relays D, d; corresponding to the relays D2, d2 of Fig. 3, are connected with a three-phase section A , A2, A3. Here the relays D, d are directional in character, and the invention is carried out in a different manner. With an internal fault fed from both ends, relays D, d operate to energize relays E, e which connect relays S, s to the full voltage of batteries J , j so that contacts S , s open and contacts S , S , s , s close. Contacts El, e having been closed, the circuit-breakers are tripped. With an external fault causing a heavy straight-through current from B to b, relays D, c operate. The relay c energizes a relay l which connects the relay S to the battery j through a resistance p to reduce the current so that the contact S opens, but the contacts S , S are not closed. The relay E is operated by the relay D but the tripping circuit of the circuit-breaker B remains open, and although the relay s is fully energized the relay e is not energized and the circuit-breaker b is not tripped. Fig. 7 shows the preferred embodiment of the invention. Here the arrangement is similar to Fig. 3, but the relays F , G and f , g are replaced by single polarized relays U, u respectively, having two sets of contacts. Furthermore, the relays E, U and e, u do not control the tripping circuit directly, but through additional relays V, v, while the time contacts E , e are provided not on the relays E, e but on additional relays X, x, connected in parallel with the relays E, e. In addition the relays L, l have an added function of borrowing the pilot wires from telephone apparatus. The current coils of the relays C, c, and the relays D, d are energized from transformers M , M , M and m , m , m , while the potential coils of the relays C, c are supplied from transformers N, n. The relays C, c have additional normally closed contacts, through which the relays E, e are energized, while one of the elements of each of the relays D, d, i.e. D , d , has additional normally closed contacts D , d , through which the relays L, l are energized if the element of the relays C, c which operates is not the element C7, c corresponding to the elements D , d . In this way the cutting out of the section on internal earth fault is assured, even though there be a simultaneous external interphase fault.

摘要： 310,984. Reyrolle & Co., Ltd., A., Leeson, B. H., and King, O. C. F. Dec. 6, 1927. Selective distant control systems and apparatus; tell-tale apparatus.-Relates to a remote control and indicating system in which three line wires are utilized in pairs for the transmission of selective and executive currents from the control station and of indicating currents from the substation and in which a clean metering circuit over a pair of line wires can be established. The lower half of Fig. 1 shows the control station connected by line wires 10 - - 12 in a cable having a lead sheath 13 to the sub-station. Selection of appaiatus :-The operation of the selector push 230 energizes one coil 240 of the stepping magnet which rotates the control station selector 220 a half-step and locks itself and sends an impulse over wires 11, 12 to the sub-station polarized relays 130, 135. Relay 130 energizes selector relay 120 which closes the circuit of the selector stepping magnet 51 of the selector 50, but relay 135 which controls the metering circuit as will be subsequently described, is ineffective as relay 130 is operated. The energization of magnet 51 closes contacts 52, 53 to apply battery 100 or an alternating current source to line wire 10 and lead-sheath 13. At the control station when the push 290 is released this source over lino wire 10 and the lead sheath 13 energizes coil 241 to step selector 220 a second. half step. Selection of the third and later positions is obtained by further operations of the push 230. The construction of the indicator and selector mechanism may be as described and interlocking mechanism may be provided as described in Specifications 307,379, 307,381, 307,383. In a modification the two selectors may be driven by two solenoids connected in series the arrangement being such that the first movement of either solenoid causes, as by short-circuiting a resistance, the current to increase to ensure the proper energization of the other solenoid. Indicating circuit :-During selection the indicating circuit is opened at contacts 244 and on completion of the selection an indicating circuit is closed over line wires 10, 12 for the polarized relay 210 from the indicating bus bars 112, 113. In the first position " off normal " of the selector 50, the bus bars 112, 113 are connected through contacts 27, 28, 73, 74 to the substation battery 100 with polarity depending on the position of the circuit breaker 20. The polarized relay 210 energizes one or other of relays 213, 2114, which control an indicating device and lamps 301, 306. In the third position the indicating bus bars 112, 113 are associated with a thermostatic switch 30 and associated relay 31. Operation of circuit breaker :-Push 260 trips and push 265 conespondingly closes the selected circuit breaker by energizing the line wires 11, 12 to operate relays 130, 135 in the opposite sense to that in which they were energized during selection so that executive relay 140 is actuated and closes a retaining contact 143 and a contact 144 in the circuits of the trip relay 160 and close relay 170. Relay 135 as during indication is ineffective since relay 180 is operated. The circuits of the trip and close relays also include contacts 23, 24 associated with the circuit breaker so that the latter if open is closed by the energization of the appropriate operating coils 21 or 22, relay 160 or 170 being meanwhile locked by contact 163 or 171. Transmission of meter readings : Meter readings may be obtained in all selector positions and after the desired selection a metering relay 135 is operated by metering push 270 through resistance 279 so that the selecting relay 130 which is in series is not operated. The close meters relay 150 and the auxiliary relay 155 are actuated so that metering bus-bars 118, 119 are connected through contact 158 to line wires 10, 12 with which meters 290 - - 292 are associated by contact 277 on the metering push 270. The bus bars 118, 119 are connected through the selector 50 to meter transformers 40, 41, 42 according to the selector position. The return to normal of the metering push 270 which is of the rotary type (Figs. 2 - - 5, not shown) closes contacts 274, 276 to send current of opposite polarity to line wires 11, 12 through resistance 279 so that relay 135 is oppositely energized. Contacts 136 on closing energize the release meters relay 138 to de-energize relay 155 and restore the indicating circuit. In a modification a metering system similar to that described in Specification 307,379 may be employed. Telephone and alarm circuits. These are associated with the zero or normal contacts of the selectors. The telephone push 280 extinguishes lamp 301 and energizes line wires 11, 12 so that executive relay 130 is operated to complete the telephone; buzzer 182 and speaking circuit 180 over the metering circuit 10, 12. Calls from the substation are effected by push 183 which is electromagnetically looked by electromagnet 186 in all, except normal, positions of the selectors. Current interrupted by interrupter 187 is thus sent over line wires 10, 12 to the control station and operates relay 210 to operate relay 213 and, since the alarm relay 250 is energized in the normal position of the selector, lamp 306 and buzzer 305 are operated. An alarm is given by automatic operation of a circuit-breaker or the operation of thermostat 30 causing the alarm relay 190 to be energized momentarily. Relay 190 locks itself until released by operation of the selector and applies current to line wires 10, 12 in opposite direction to that of a telephone call. The operation of relay 210 thus energizes relay 213 or relay 214 to change over lamps 301, 306 and operate the buzzer 305. Relays 213, 214 control separate indicator discs so that a distinguishing indication is given, moreover, in the case of a telephone call interrupter 187 is in circuit so that the buzzer 305 is intermittently operated. Modification of alarm circuit:-To enable an alarm to be given to the control station during the time meter readings are being taken the substation alarm relay 190, Fig. 7, may be provided with extra contacts controlling an auxiliary alarm relay 480 and its retaining circuit includes a time limit relay 490 in addition to selector contacts. With this arrangement an alarm initiated by any change in the substation apparatus during metering breaks the metering circuit and an alarm is transmitted until the time-limit, relay 490 operates when the metering circuit is re-established. At the control station the operation of the meters push has prepared the circuit of an alarm relay 331 which is energized by an alarm and locks itself until released by the operation of push 335. Arrangements for express selection. To obtain express selection after the operation of contacts 231, 233, Fig. 1, if boths sets of contacts are closed the resetting movement of solenoid 241 will automatically re-energize the starting solenoid 240. The arrangement is similar to that described in Specification 307,379 and may be effected by a special push or by the provision of extra contacts 232 on the push 230 which are closed by rotating the push or alternatively by retaining the push depressed. When selfrecording indicating mechanism is employed at the control station the receipt of an alarm signal may be arranged to cause the selectors to perform a complete selecting and indicating cycle. For this purpose the control station relay 250 is energized in the normal position so that an alarm causes relay 214 to energize an ,additional, alarm. relay 310 which locks itself, starts an express selection over a circuit including contacts 215 controlled by the indicating mechanism so that the receipt of the indication starts the next selecting movement. Relay 310 energizes an auxiliary relay 320 which locks itself till released by theoperator at the control station. The operation of the selector to the fourth position releases the alarm relay 310 but the selecting circuit is maintained by contacts of the auxiliary relay 320 in conjunction with contacts operated by cam on the selector so that the cycle is completed. The control operator can check the system by energizing alarm relay 310 by a push 315. Repeater system for metering circuits : Meter readings directly taken over the line wires would be unreliable owing to variations in the line conditions. Fig. 6 shows a system in which current readings are taken when selector contacts 401 or 411 are closed, potential readings are taken when contacts 421 are closed and wattage readings are taken when contacts 431 are closed. In each selected position one of relays 402, 412, 422, 432 is energized and associates the source with current bus bars 442, 443 or 450 - - 452 and voltage bus bars 445, 446 or 453 - - 455, respectively The bus bars control a group of master repeaters 460 one for each type of meter required each having an operating coil or coils 461 controling a pointer 462 carrying contacts 464. The follower element 466 connects through contacts of the operated relay 402 the substation battery to one side or other of the field coil 471 of a common auxiliary motor 470. The motor 470 drives a rheostat arm 472 to control the energization of the follower elements' 466 which are in series with the line wires 10, 12 through the contacts of meter relays 150, 155, Fig. 1. The control station meters 290 - - 292 are selectively connected in the circuit of line wires 10, 12 and comprise ammeter movements appropriately calibrated.

摘要： 307,384. Reyrolle & Co., Ltd., A., Leeson, B. H., and King, O. C. F. Dec. 6, 1927. Selective distant centrol systems.-Relates to a remote control and indicating system in which an electromagnetic, switching device at the substation normally allows the substation indication transmitting apparatus access to certain line wires but on the actuation of the control station transmitter disconnects the substation transmitter and connects the substation receiver to the line wires. The system employs drum selectors of the type described in Specification 307,379. The lower half of Fig. 1 shows the control station connected by line wires 40 - - 42 to the substation shown in the upper half of the Figure. Selection of apparatus. The operation of selector push 230 energizes one coil 235 of the stepping magnet which rotates the control station selector 220 a half-step thus locking itself and sending an impulse over wires 41, 42 to substation polarized relay 140. Relay 140 energizes selector relay 130 which closes a holding circuit for relay 140 through coil 143 and energizes the selector relay 75 which closes the circuit of the stepping magnet 71 of the selector 70 which by closing contacts 72, 73 applies the substation battery 120 to the line wires 41, 42. At the control station when the push 230 is released the batteries 120, 210 in series energize relay 237 which is not actuated by a single battery and energizes coil 236 to step selector 220 a second half step. Selection of the third and later positions is obtained by further operations of the push 230. Indicating circuit. During selection the indicating circuit is opened at contacts 222 and on completion of the selection an indicating circuit is closed over line wires 40, 42 for the polarized relay 200 from the indicating bus bars 160, 161. In the first position " off normal " of the selector 70 the bus bars 160, 161 are connected through contacts 51, 52, 93, 94 to the substation. battery 120 with polarity depending on the position of the circuit breaker 50. The polarized relay 200 energizes one or other of relays 203, 204 controlling lamps 285, 286. In the third position the indicating bus bars 160, 161 are associated with a thermostatic switch 60 and associated relay 62. Operation of circuit breaker. Push 240 trips and push 250 correspondingly closes the selected circuit breaker by energizing line wires 41, 42 to operate relay 140 in the opposite sense to that in which it was energized during selection so that executive relay 150 is actuated and closes a retaining contact 155 and a contact 154 in the circuits of the trip relay 180 and the close relay 185. These circuits also include contacts 54, 55 associated with the circuit breaker so that the latter, if open, is closed by the energization of the appropriate operating coils 57 or 58, relay 180 or 185 being meanwhile locked by contact 183 or 187. Transmission of meter readings. The desired contacts on selector 70 are selected and executive relay 150 is operated by metering push 260 which when released leaves contact 262 operated until released by movement of the selector 220 so that metering bus bars 162, 163 are connected to line wires 40, 42 with which meter 266 is associated. The bus bars 162, 163 are connected through the selector 70 to a current transformer 61. Telephone and alarm circuits. These are associated with the zero or normal contacts of the selectors. The telephone push 270 extinguishes lamp 285 and lights lamp 284 to indicate that the system is inoperative and energizes line wires 41, 42 so that executive relay 150 is operated to complete the telephone buzzer 170 and speaking circuit 171 over the metering circuit 40, 42. Calls from the sub-station are effected by push 173 which is electromagnetically locked by electromagnet 176 in all except normal position of the selectors. Current interrupted by interrupter 177 is thus sent over line wires 40, 42 to the control station and operates relay 200 to operate relay 203 and since the alarm position relay 290 is energized in the normal position of the selector, lamp 286 is lighted and buzzer 287 is operated. An alarm is given by the automatic operation of a circuit-breaker or the operation of thermostat 60 causing the alarm relay 190 to be energized momentarily. Relay 190 locks itself until released by operation of the selector and supplies current to line wires 40, 42 in opposite direction to that of a telephone call. The operation of relay 200 thus energizes relay 203 or relay 204 depending on whether a telephone or alarm call is sent to change over lamps 285, 286 and operate the buzzer 287. Relays 203, 204 control separate indicator discs so that a distinguishing indication is given; moreover in the case of a telephone call interrupfer 177 is in circuit so that the buzzer 287 is intermittently operated. If an alarm is initiated when the selector is " off normal " the alarm relay 190 is energized and locked, but the alarm is stored until the selectors are returned to normal. Modification of alarm circuit. To enable an alarm to be given to the control station during the time meter readings are being taken the substation alarm relay 190 may be provided with extra contacts controlling an auxiliary alarm relay 330, Fig. 3, and its retaining circuit includes contacts of a time limit relay 340 energized by the auxiliary relay 330. With this arrangement an alarm during metering breaks the circuit over line wires 40, 42 and establishes the alarm circuit over line wires 41, 42. A metering relay 156 controlled by relay 150 is provided so that the auxiliary relay 330 is energized only in metering selector positions. The alarm energizes relay 360 which locks itself and the alarm circuit is maintained until the timelimit relay 340 operates and the metering circuit 41, 42 is re-established. Arrangements for express selection. To obtain express selection after the operation of contacts 232, 233, Fig. 1, if both sets of contacts are closed the re-setting movement of solenoid 236 will automatically re-energize the starting solenoid 235. These connections may be effected by a special push or by the provision of extra contacts on the push 230 which are closed by rotating the push or alternatively by retaining the push depressed. A barometer type pointer carrying contacts and co-operating with the selector pointer may control a relay so that the express selection is stopped when the pointers are in agreement. Automatic operation of selectors on receipt of an alarm. When self-recording indicating mechanism is employed at the control station it is necessary to arrange that the receipt of an alarm signal causes the selectors to perform a complete selecting and indicating cycle. In this modification (Fig. 2 not shown) the control station alarm position relay 290 is energized in the normal position of the selectors so that an alarm causes relay 204 associated with the polarized relay 200 to energize an additional alarm relay which locks itself and starts an express selection and energizes an auxiliary relay which gives the alarm and locks itself till released by the station attendant. The operation of the selector to the fourth position releases the additional alarm relay but the selecting circuit is maintained by contacts of the auxiliary relay in conjunction with contacts operated by cam on the selector shaft so that the selecting and indicating cycle is completed. The control operator can check the system by energizing the additional alarm relay. Modified system employing pre-selector relays. This system is fully described with reference to Fig. 28 of Specification 307,379. The selecting and executive pushes (Fig. 4 not shown) respectively are associated with transmitting coils and a release coil of a transmitting switch the. construction of which forms the subject-matter of Specification 307,385 and provides for the locking of the control station apparatus during selection. The control station selector is driven a half step by the selecting impulse and an additional half step by the energization of the release coil from the substation. Indications are given from the substation by means of a similar switch and actuate an indicator also described in Specification 307,385 having positive and negative coils respectively corresponding to coils 460, 465, Fig. 28, of Specification 307,379. The centralization of the armature of the indicating switch (Fig. 7 not shown) leaves a, slide in its last operated position until centralized by the control station selector, so that an alarm causes an express selecting and indicating cycle to be started which is stopped by the absence of indicating current in the " normal " position since the operation of the substation selector will have de-energized the alarm relay at that station. A checking, selecting and indicating cycle can be started by the control station operator moving the slide to the alarm position by hand. Construction of pre-selector relay. Fig. 8 shows a modified construction of pre-selector relay comprising a beam restored to normal by gravity and carrying insulated members 436, 437, 438 connected to the line wires 426 - - 428 and co-operating with contacts 440 - - 449 corresponding with similarly numbered contacts in Fig. 28 of Specification 307,379. The operating coils 432, 433 are unequally spaced from the pivot so that precedence is given to one function in the event of simultaneous operation without interfering with the normal operation from either the control or substation. This type of switch may be extended for more complicated systems such as by duplication of the transmitting and receiving apparatus. In this event the beam is replaced by a plate mounted on a central ball joint operated by more than two magnets the desired exclusive use of the line wires for the function first started being obtained by mechanical interlock.

摘要： 307,383. Reyrolle &. Co., Ltd., A., Leeson, B. H., and King, O. C. F. Dec. 6, 1927. Electric selective distant control systems; illuminated stencil indicators.-An indicating mechanism for giving selective indications of the condition of a number of apparatus is provided with a mimic circuit diagram superimposed on the indicators and hand operable members corresponding to the indicators so that disagreement between the automatic and hand operated indication is readily apparent. A remote control system is described similar to that described in Specification 307,381 employing selectors at the control station making half notch movements as described in Specification 307,379. In addition similar indicating mechanism to that described in Specification 307.381. in which an automatic record of the condition of the substation apparatus is obtained, is described. The Figures show an indicator in which the hand operation of the selecting and operating keys produces the record. The indicator comprise a panel A behind which are five movable discs N - - R mounted on the selector spindle B and separated by fixed separator plates S. The discs and plates have holes and slots and coloured markings and are visible through indicator windows A and the central aperture A . The unit selector disc N is mounted on the selector spindle and masks all indications except that of the selected apparatus. The operating pushes U, V, T rock the disc O and obscure the indicators until released when one of the indicating discs Q or R operated by the control station polarized relay will give an indication of the condition of the selected apparatus. The meters push W controls the disc P to mask the apparatus condition indicators and indicate the meter reading selected.

摘要： 228,265. Reyrolle & Co., Ltd., A., Leeson, B. H., Nalder Bros. & Thompson, Ltd., and Nalder, F. H. Nov. 1, 1923. Retarding and time-limit devices.-In a relay, the inverse time delay action or time lag is adjusted by alteration of the inertia of the rotary moving member of the relay itself, and this alteration is effected by the addition of one or more inertia discs or rings to the spindle of the moving member. The discs may be slotted and placed in a light cup. The relay spindle A carries a very light cup B to which is secured a pin E and in which may be placed one or more than slotted discs F, the slotted part G engaging the spindle A and pin E. The cup B is cut a.way at H to facilitate removal of the discs and carries a contact B , while, the discs are bored at F to compensate for the slot G and produce symmetry of loading on the spindle. The cup is of negligible inertia and the desired amount of inertia may be added by placing the required number of discs in the cup.

摘要： 163,420. Reyrolle & Co., Ltd., A., Leeson, B. H., and Mirrey, J.. Feb. 9, 1920. Electromagnetic switches; retarding - devices. - Relays, circuitbreakers, or like apparatus are retarded in action by a train of wheels provided with a centrifugal governor. The figure shows a relay acting to close contacts K in a tripcircuit a certain time after the occurrence of an overload in the circuit. The relay magnet B attracts a pivoted armature C restrained by an adjustable spring E and thus releases a weighted lever A. The fall of the lever, checked by a train of wheels driving a double conical pendulum O, brings the contacts together at K, the engagement between the lever and the train of wheels being such that the lever falls freelv after the set time interval has expired. A bottom plate P is formed with guide openings which limit the movement of the pendulums. The instrument is provided with a screw adjustment T for altering the initial position of the lever A, and with a visible time scale R.

摘要： 516,530. Gas-blast switches. REYROLLE & CO., Ltd., A., COATES, F., LEESON, B. H., and ALLAN, A. June 21, 1938, No. 18387. [Class 38 (v)] An air or gas - blast circuit - breaker has the arc formed within an enclosure having on one side only in the wall thereof one or more lateral discharge vents past which the arc is drawn, and the blast is derived from a source external to the enclosure and forced through the arc path and out of the enclosure through the vents, the blast-supply to the enclosure being controlled by a valve member which is constituted by one of the relatively-movable contacts or by a part associated therewith. The gas may be air, nitrogen, carbon dioxide, argon, or a gaseous fluorinated alkyl chloride such as dichloro - difluoro - methane.. The invention is described and illustrated in Figs. 1-8 (not shown), in its application to certain Figs. of Specifications 516,529 and 516531, the arrangement of Fig. 1 (not shown) including also a plug associated with the arcing structure and filling the tip of the hollow movable contact in the closed position so as to free the blast near the beginning of the opening movement. Specification 516,532 is also referred to. The arcing enclosure of Fig. 9 has vents K' and aligned inlet ports K supplied by pipe G , the ports being successively uncovered by a spring-controlled valve K which is normally held closed by a projection K' on the movable contact C. Fig. 10 shows an arrangement for withdrawing the movable contact C into clean gas in the open position, by placing a plate M across the container D so as to leave a clean-gas space M below it. The gas reservoir F contains contactactuating mechanism, the operation of which. before the contact actually moves, opens a valve M by means of the system M'... M . Thus the container D may all be filled with compressed gas while the switch is closed, the valve allowing the discharge side to exhaust and the blast to be set up before the contact moves, so obviating the need for perfect gastight closure of the vents B . At the end of the opening stroke, pressure is again restored by closure of the valve. Where a solid contact C and separate gaspipe are used, the valve is placed in the latter, and the compartment M mav contain insulating liquid. Alternatively or additionally, a series-break M', M may occur in timed relation to the main break and in a gas or liquid-filled casing M'. The Specification also refers to an arrangement which is similar to that of Figs. 7, 8 of Specification 516,529. The rod-contact may be kept fixed and circuit opened by movement of the arcing enclosure.
