摘要： 1,148,553. Signalling over power lines; generating oscillations. ZELLWEGER Ltd. 7 Feb., 1967 [25 April, 1966], No. 5795/67. Headings H3B and H4R. Signalling over power circuits is achieved by the repetitive connection and disconnection of an oscillatory circuit to the line via electronic switches, the oscillatory circuit being disconnected at a supply voltage peak, connected a half-cycle of the supply voltage later, and disconnected after a further odd number of supply voltage half-cycles. As described the circuit of Fig. 3 is used to generate pulses U s at the peak of each half-cycle of the supply voltage U, the exact phase of the pulses relative the supply voltage being adjusted by the variable resistor 15 in the phase shifting circuit 14, 15. The pulses U s are used to synchronize a monostable multivibrator, Fig. 4 (not shown), so that it triggers in one direction at the supply voltage peak, remains in this state for a half-cycle of the supply voltage, and then remains in the other state for an odd number of half-cycles, e.g. 1, 3, or 5, of the supply voltage. The resulting waveform is applied as triggering voltage U t to the circuit of Fig. 1, to trigger the thyristor 12 so that the thyratron is non-conductive for onehalf-cycle of the supply frequency allowing capacitor 10 to charge up to the peak value of the supply voltage, the thyratron is then triggered and stays triggered for an odd number of half-cycles, so that the resonant circuit formed by capacitor 10 and the primary of transformer 9 is closed through the thyristor 12 and diode 11 so that it resonates and applies the resulting high-frequency oscillations to the power circuit over transformer 9.

摘要： 967,072. Signalling over power circuits. ZELLWEGER Ltd. Jan. 12, 1961 [March 8, 1960], No. 1393/61. Heading H4R. A control signal receiver adapted to provide an output control signal in response to input control signals superimposed on a power supply circuit comprises means for detecting the input control signal level at the input to the receiver, means for detecting the interference level at the input to the receiver and comparator means for ensuring that the output control signal is provided only if the input control signal level exceeds the interference level. The control signals may be used for remote control of hot water heaters or street lights. A receiver comprises input terminals 30, 31 connected to the power supply. A filter network comprising capacitors 32, 36 and transformer 34, 35 rejects signals of the frequency of the A.C. supply. A surge suppression resistor 33 is provided. Signals passing through the filter network are rectified by rectifier 37 and applied to a network comprising capacitors 38, 39 and resistors 42, 43. The time constant of capacitor 38 with its discharge resistor 42 is greater than the duration of a control signal while the time constant of capacitor 39 with its discharge resistor 43 is such that a control signal charges capacitor 39 to fire a discharge tube 40 and operate a relay 41. Resistor 42 is ten times higher than resistor 43 and a continuous interference voltage produces in capacitor 38 a charging voltage ten times higher than in capacitor 39. In an alternative arrangement (Fig. 4) circuit 35 1 , 36 1 is tuned to the control signal while circuits 35 11 , 36 11 and 35 111 , 36 111 are tuned to upper and lower mains harmonics adjacent the frequency of the control signal. Component values are such that interference signals charge capacitors 38, 39 equally but oppositely to give zero output, whereas control signals charge capacitor 39 more quickly than capacitor 38 to provide a voltage sufficient to fire discharge tube 40 and operate relay 41. Where interference signals embrace a wide frequency band, secondary circuit 35 11 , 36 11 (Fig. 5) is a resonant circuit with a broader pass band than circuit 35 1 , 36 1 and is connected to a bridge network comprising a parallel resonant circuit 35 111 , 36 111 tuned to the frequency of the control signals. Interference signals charge capacitors 38, 39 equally but oppositely while a control signal produces no voltage across capacitor 38 and 37 but charges capacitor 39 sufficiently to fire discharge tube 40 and operate relay 41. The filters tuned to the interference signals may be simple R.C. networks. A power distribution system including a transformer station and a control signal generator are described (Fig. 1, not shown). Specification 623,636 is referred to.

摘要： 924,403. Electric analogue calculating systems. ZELLWEGER Ltd. FACTORIES FOR APPARATUS & MACHINES USTER. Jan. 31, 1961 [April 8, 1960], No. 3675/61. Class 37. A variable function is averaged by applying an equivalent electrical quantity to an R-C network having a time constant variable in a predetermined manner and arranged to present the mean value of the function as a voltage across the capacitor of the network. The R-C network in its simplest form consists of a variable resistance 12 connected in series with a fixed capacitor 11 across a generator 1 which produces the function U(t) with respect to time t. An electric motor 14 supplied from a network 15 through a switch 16 varies the resistance 12 according to the law dR/dt = 1/C, where C is the capacitance of 11. With this arrangement the voltage across 11 is exactly the mean of the function U(t). A voltage indicator 2 measures this mean value directly and is ideally of infinite resistance. If, however, its resistance is finite a further variable resistance 17 may be connected across the indicator and varied by the motor 14 to give the desired variation of time constant. The resistance 12 may be a potentiometer driven by the motor 14 so that the resistance varies linearly with time but other resistance changes may be used e.g. of a thermal, optical or electronic nature. The time constant may be varied by using a variable capacitor instead of a resistance. Impedance circuits such as a Miller integrator may be used, the time constant in this case being varied by altering the amplification. The resistors or capacitors may be variable in steps instead of continuously. Specification 681,477 is referred to.

摘要： 887,599. Electric measurements. ZELLWEGER Ltd. Jan. 5, 1959 [Jan. 18, 1958], No. 389/59. Class 37. [Also in Group XL (b)] In apparatus producing an electrical signal representing the denier of yarn or other filament as it passes the apparatus, zero errors are removed by periodically moving the yarn or the apparatus so that the yarn is first in a region of high measuring sensitivity and then in a region of lower sensitivity, the resulting electrical signal being passed, through a circuit which removes the D.C. component, to a rectifier which provides an output dependent upon the peak-to-peak value. In Fig. 1, the yarn 1 is fed between two plates of a capacitive measuring device 3, 4, 5, the output of which depends upon the thickness of the yarn. A vibrator 18 periodically moves the yarn away from the centre of the plates so that, for example, when the yarn is of constant thickness, a signal such as in Fig. 5a is produced having a constant amplitude of variation but a D.C. level which may drift, as shown by the dotted lines. This signal is passed through a filter 21 which removes the D.C. component producing a voltage as shown in Fig. 5b which is passed through a rectifier circuit 11 producing an output corresponding to the peak-to-peak voltage. The rectifying voltage is amplified at 14 and passed to a measuring or recording instrument 17 and also if desired to means which operates an alarm if the thickness is outside prescribed limits. The measuring apparatus 3, 4, preferably has plates shaped as shown in Fig. 6, so as to provide two regions of different field, the yarn being vibrated between the two positions 1. It is stated that the apparatus 18 may be mechanically, eleotromagnetically or pneumatically operated and that alternatively the measuring device may be vibrated.

摘要： 886,433. Warp tying machines. ZELLWEGER Ltd. March 26, 1959 [April 2, 1958], No. 10640/59. Class 142(1) The two ends of a warp tying machine mounted on telescopic legs can be raised or lowered together and one end can be adjusted separately by manipulation of a single hand crank, to enable the machine to be levelled on an uneven floor. The legs are operated by screws 16 engaging nuts 14 on the inner members of the legs; the screws carry bevel gears 17, of which the one shown meshes with a gear 18 loose on a shaft 19, whereas the gear 17 at the other end of the machine meshes with a gear fast on the shaft 19. The operating crank consists of an arm 27 pivoted to the shaft by a pin 31 and having a handle 35 similarly pivoted to it. Spring-loaded plungers 34, 37 in the arm engage flats in the shaft and the handle to hold the crank in the required configuration. As shown, the arm 27 is in contact with the gear 18, which it presses against the end of a tubular member 3 of the machine; rotation of the gear 18 is thereby prevented by friction, and rotation of the shaft 19 is prevented by friction between the arm 27 and the gear 18. On turning the arm 27 and the handle 35 through 180 degrees about their pivots 31, 40, a tooth 38 on the arm enters a notch 39 in the gear 18; the gear and the shaft 19 can then be rotated to adjust both legs simultaneously. By turning the arm 27 through 90 degrees from the position shown so that it is in line with the shaft 19, the shaft can be rotated to adjust the far leg only; the gear 18 remains stationary, since friction between it and the tube 3 is greater than between it and the shaft 19.

摘要： 832,261. Knot-tying. ZELLWEGER Ltd., FACTORIES FOR APPARATUS & MACHINES USTER. April 4, 1957 [April 4, 1956], No. 11040/57. Class 112 Two threads b, laid side by side, are knotted together by forming a loop a therein, winding the thread ends c around the threads b at the base of the loop for a turn and a half, as at d, passing the ends c through the loop, and pulling the threads to tighten the loop. In apparatus, Fig. 4, for forming the knot a hollow mandrel 1 is mounted on a casing 3 and slidably supports a rod 4 which is formed at its outer end with a hook 5 and is linked at its inner end by a pin 7 with a lever 8 adapted to be oscillated by means of a cam 9 carried by a shaft 10. An ejector 11, slidable in a longitudinal groove formed in mandrel 1, is linked at its inner end by a pin 12 to a lever 13 adapted to be oscillated by a cam 14 on shaft 10. A gear 15 on shaft 10 meshes with a gear 16, the hub of the latter being journalled on mandrel 1, and gear 16 rotating three times for each revolution of shaft 10. A sleeve 17, keyed to but slidable on the hub of gear 16, carries at its outer end a thread-gripper 18 and is formed at its inner end with a circumferential groove engaged by a fork 19. The later is fixed to one end of a slidable rod 20 linked at the other end by a pin 21 to a lever 22 adapted to be reciprocated by a cam 23 on shaft 10. The arrangement is such that the ends c are seized by the gripper 18 and are carried around the mandrel 1 to form the loop a, the outer end of the loop lying inwardly. During the next revolution and a half of the gripper, sleeve 17 is moved successively outwards, inwards and finally outwards to form the loop d and to place the thread ends in the hook 5. The latter is then retracted to pull the thread ends through loop a to form the knot. The ejector 11 then moves outwardly to remove the knot from the mandrel, and finally the threads are pulled to tighten the knot and to release the ends from the hook. In a modification, Fig. 9, the knot is formed by a rotary bill which is carried by a shaft 34 and comprises a fixed blade 32 and a movable thread-cutting blade 33. A gear 36 on a shaft 34 meshes with a gear 37 on a shaft 38, shaft 34 rotating twice to each revolution of the latter. A lever 42 is adapted to be oscillated by a cam 39 on shaft 38, and carries an arm 43 formed with a thread-holding notch 44 adapted to carry the thread ends c from one side to the other of the knotting bill.

摘要： 1293465 Automatic vending systems ZELLWEGER Ltd 12 Feb 1970 [26 March 1969] 6801/70 Heading A4T [Also in Division G4] In an automatic vending system an article is provided with information, e.g. a price or weight label, which is automatically read and, if the article is found to be within predetermined limits it is automatically released to the customer. In this figure an article 1 is marked and is passed on a conveyor into the reading zone 2 of a reader 3. The reading from the article is passed by way of a line 3b to a computor 4 which identifies the article from its marking and passes the result to a store 5. The article then passes by means of a conveyor 6 to a measuring device 7 which weighs the article and passes this information to a comparator 8 which also receives the signal stored in the store 5 by way of a line 5a. If the two signals are in general agreement the article is passed by a conveyor 9 to a container 11 and a signal is passed to a totaliser 13 which passes the signal to a cash register 15. This system is repeated for as many items as the customer passes through the system. If the comparator 8 finds the two signals incompatible the article is returned by a conveyor 10 to the start of the system. After payment indicated by the register 15 has been made, or debited to an account, the customer presses a button 12 on the reader 3 and the compartment 11 releases all the articles therein. In the event of a fault or unsuccessful reading a convey 6a may return the article to the start of the system. The sequence of reading and weighing may be reversed or both may be performed simultaneously.
