摘要： 611,923. Automatic control systems for melting-vessels. POOL, W. Jan. 4, 1946, No. 380. [Class 38 (iv)] Temperature control.-In a melt-spinning apparatus for producing artificial filaments or the like, each unit of a battery of 12 electrically-heated vessels of the kind described in Specification 592,992 (Fig. 1, not shown), has a thermocouple giving an indication of its temperature. In the control mechanism 12, Figs. 3, 4, a motor-driven shaft 20 rotates an arm 16 carrying bridge pieces 17, 25, which respectively interconnect slip ring 18 with the 12- contact bank 21, and slip ring 26 with the 12-contact bank 27, the slip rings and contacts being mounted on insulating disc 19. The contacts of bank 21 are each connected to one side of the corresponding thermocouple (return leads being common) and the slip ring 18 to the input of the control instrument 11, Fig. 2 (not shown), which indicates the temperature of the thermocouple to which it is connected on a dial, and also (for example thermionically) closes or opens a relay in the A.C. supply from transformer 31 to slip ring 26 according as the temperature of the vessel presently under test is above or below an adjustable datum. The contacts 27 are respectively connected to a bank of 12 solenoids 28 (return leads common), each of which controls the heater switch of the corresponding melting vessel through its own mechanical operator. Energization of a solenoid lifts the associated lever 46 which controls the engagement of the driven member of clutch 35 with the driving member 36 which is fast to a shaft 20, and allows the two members to rotate together, while non-energization allows lever 46 to remain down, tripping lever 40 to disengage the clutch. The end 51 of a bell-crank 52 rests in a notch 50, while member 37 is stationary, and rides on the periphery of the member when it is in motion. The motion of the bell-crank tilts a hooked lever 64, about pivot 65,. which is laterally oscillated once in 15 seconds by lever 79 driven by rocker 78 engaged by a crank-pin 73 on a chain-driven sprocket 70 geared to shaft 20. The hooks alternatively drive a slidable notched insulating strip 58 in either lateral direction to operate the appropriate heater switch 56 in the on or off direction. Thus, each vessel temperature is cyclically tested and if below a fixed datum the appropriate solenoid is energized, member 37 rotates, bell-crank 52 tilts lever 64 and strip 58 is urged to switch on the appropriate heater for the ensuing cycle. If the temperature exceeds the datum, the solenoid is de-energized, clutch 35 is tripped, member 37 is stopped with its notch engaging the bell-crank, and lever 64 is tilted to urge strip 58 to switch off the appropriate heater. The cyclic testing process is continuous, completing itself in 3 minutes, and a pointer 84 is driven by sprocket 85 at the same speed as shaft 20 to indicate on a dial the vessel under instantaneous test. A lamp behind each dial member, illuminated through a switch 86, glows when power is supplied to the appropriate vessel heater. In a modification, the power switches may be operated directly by the solenoids, or by wedge-shaped projections on a continuously rotating drum which may be shifted axially, to engage or disengage a particular switch, by a single solenoid operable by the selector means.

摘要： 606,701. Injection - moulding machines. POOL, W. Jan. 4, 1946, No. 381. [Class 87(ii)] A fusible filament-forming polymer, while still in a molten state at the end of its polymerization, is formed into sticks by being forced from a heated vessel 4, by means of an inert gas, through a valve 9 into perforation 34 in an intermittently rotated ring 22. The vessel may be a polymerization vessel and a battery of polymerization vessels may be used. The ring 22 is mounted between three fixed rings 21, 23, 24, and the rings are secured to a frame 15 by studs 25. The ring 23 is provided with a gas-escape groove 67 and a recess 65 for the circulation of cooling water. Nitrogen or other inert gas may be passed through each perforation before filling with molten material. The moulded sticks are ejected through a hole in the ring 21 into a shoot by a plunger working in a cylinder 46. Any flash that may have formed on the sticks is cut off during their passage through the ring 21. A filter 12 is provided at the outlet from the vessel.

摘要： 522,017. Forming staple fibre yarn &c. POOL, W., Dec. 1, 1938, No. 35016. [Class 120 (ii)] A staple 'fibre yarn or like product is formed by feeding a succession of flat wide groups of separated fibres to the tail of the yarn being produced in a direction across the length of the tail which is rapidly rotated solely by means of a gaseous vortex, the ends of the groups of fibres being taken up by the rotating tail and the vortex having an axial component away from the tail whereby each group of fibres is successively drawn away, after its ends are taken up, to form a new tail to the yarn which is continuously drawn away, as it is formed, against the drag of the axial component of the gaseous vortex. The groups may be formed by cutting from the separated filaments at the end of a bundle; the fibres may be still further separated after they are cut, and the groups of fibres may be mixed after they are cut with pre-formed groups of other fibres. As shown the filaments 1 from a package 2 formed by the method described in Specification 504,399 are separated by compressed air emerging from a flat nozzle 14, are further separated by compressed air emerging from a flat nozzle 17, and are cut by a cutter 18 of 'the hair-clipper type which is continuously operated and cuts the filaments when they are depressed into engagement with the cutter by deflector rods 21. The filaments emerging from the nozzle 17 are blown along a diverging channel plate 44 and as the ends of the filaments reach the end of the plate they are drawn downwards into contact with the tail 49 of the staple fibre yarn by air drawn through perforations 48, in the plate by an ejector 47 supplied with compressed air through a valve 37. As the ends of the filaments become entangled with the rapidly rotating tail 49, the filaments are cut by the cutter 18 and compressed air supplied through a valve 3 enters through perforations 54 in the side of the plate 44 and sweeps the cut ends of the fibres sideways through a flat channel 51 into a tail pipe 52 supplied with air by a valve 39 communicating with an ejector 55. The pipe 52 tapers from the ejector 55 towards the plate 44 and a pipe 57 conveys compressed air through a small bore 58 leading tangentially into the pipe to form the gaseous vortex which causes the tail of the yarn to be rapidly rotated ; the yarn is drawn continuously from the plate 44 through a guide 25 by a winding device 32 ... 36. In a modification the leading ends of the fibres are swept into the tail pipe and the freshly cut ends are entangled with the rapidly rotating tail of the yarn, The cut fibres may be fed indirectly to the rotating tail of the yarn and as shown in Fig. 10 the cut fibres emerging from the nozzle 17 are sucked down into a series of compressed spiral springs 75 carried by a rotating drum 70 and as the drum rotates a half revolution the springs are allowed to expand so that the fibres are spread out 'along the length of the drum, the suction being cut off as the leading ends of the fibres reach the bottom of the drum and the ends being then blown off the drum 70 into contact with the rapidly rotating tail 49 of the yarn ; as the drum rotates further air pressure is applied over the whole of the surface thereof carrying the fibres which are then free to be swept sideways by suction into the tail pipe 52. During the other half revolution of the drum 70 the springs 75 are contracted to receive a further supply of fibres from the nozzle 17 ; the springs are contracted and allowed to expand by mechanism in a drum 79 rotating with the drum 70. In a further form, Figs. 14 and 16, the cut fibres emerging from the nozzle 17 are deflected by a rotating rod 138 on to the leading rod of one of three groups of rods 123, carried by an endless chain 124 and covered with rubber to form a gripping surface. The groups 123 are separated by groups of plain rods 122 and the rods pass over drums 129, 130, the drum 130 being perforated and the perforations communicating with a suction conduit 144 so that the fibres are held on the rods 123 and carried between a pair of flat plates 145,146 to a partly cylindrical member 100 carrying an ejector 55 in which the rapidly rotating tail 49 of the yarn is disposed. The leading ends of the fibres lying on the rods 123 as they pass over the surface of the drum 129 are blown off the rods by compressed air supplied through passages 180 in the drum into contact with the tail 49 and a mixed yarn may be produced by feeding other fibres to the rods 123. As shown. fibres are fed from a roving 115 'through a flat slot 119 to bands 120 which feed them to the rods. 123 and as the ends of the fibres are laid on the rods a roller 131 is pressed against them so that individual fibres are pulled from the bands 120 and are carried on the rods 123 with the cut fibres from the nozzle 17 to the tail 49 of the staple fibre yarn. Specifications 484,190, 489,272 and 520,084 also are referred to. According to the Provisional Specification the support constituted by the rapidly rotating tail of staple yarn may be formed or augmented by a rapidly - rotated needle-like spindle or by a twist tube, e.g., that described in Specification 519,995, the filaments may be electrified by passing them through a gate tension device or by the means described in Specification 504,400.

摘要： 520,451. Sliver-rubbing apparatus. POOL, W. Oct. 22, 1938, No. 30600. [Class 120 (i)] [Also in Group XXIV] A roller 22, Fig. 2, for driving a band, e.g., a rubbing band as used for compacting continuous assemblies of staple fibres in the preparation of textile threads, is given a rotary motion and at 'the same time is reciprocated axially. The ends of the roller have ratchet teeth 23, 24 facing in a direction opposite to that in which the roller is to rotate. Ratchet members 25, 26 of the same diameter as the roller, have teeth facing in the same direction as the roller is to rotate, these members being so arranged that when the roller is in full engagement with one of the ratchet members it is just clear of the other. The members 25, 26 are continuously oscillated by eccentrics 27, 32 arranged 180 degrees out of phase, and which drive discs 29, 33 connected to the members 25, 26 by steel tapes 31, 34. Movement of the member 25, Fig. 3, causes the roller to move to the right and be engaged by the member 26. When the movement of the members 25, 26 is reversed, the roller is moved to the left and is again driven in the same direction by the member 25. The arrangement is such that a onetooth movement of the ratchet members results in a two-tooth movement of the roller 22 which, for a part of its movement, is rotated without reciprocation. If, however, the ratchet members 'are oscillated over the space of half a tooth only, then the whole motion of the roller is one of combined rotation and reciprocation. In Fig. 1, a bundle of continuous filaments 1, with little or no twist, is drawn through a gate 3 by feed rollers 4 and delivered to an air jet 5 and thence propelled to lie above a hair clipper 6. The separated filaments are carried into the cutter 6 by a deflector 7. The forward ends of the fibres reach the point 8 of a permeable support 9 passing round a suction tube 10 perforated at 11. The upper run of the support 9 moves towards the nip of rollers 12, 13 the latter of which together with a roller 14 serving to carry an end- 'less band 15 against which bears an endless band 16 on rollers 17, 18. The rollers 13, 14 and 17, 18 have the movement described above, whereby the groups of filaments which form a continuous assembly which is compacted by the rubbing bands and when it emerges is twisted into a staple fibre 20 by the ring spinning device 21. Specification 484,190 is referred to

摘要： 519,995. Twist tube; crimping and winding yarns. POOL. W. Oct. 10, 1938, No. 29287. [Classes 120 (ii) and 120 (iii)] A twist tube for twisting yarns &c. comprises a short hollow spindle adapted to make frictional contact with a yarn passing through it and driven by a friction wheel making external contact with the spindle which is held in engagement with the friction wheel by anti-friction means; a helically-twisted strip may be secured within the plain bore of the spindle to ensure the yarn making frictional contact with the spindle. As shown, the twist tube is used in a machine for crimping and winding yarns 25, a number of crimping and winding devices being arranged around a central shaft 6; the twist tubes 28, which are mounted in a steam chamber 2, are driven by a pair of large friction wheels 31 on the driven shaft 6, and each tube is held in engagement with the friction wheels by two pairs of overlapping anti-friction wheels 33 which engage grooves in the tube and are carried by arms 35 on a block 36 slidably mounted in a sleeve 37 and pressed by a spring 38 towards the. wheels 31; the block carries an extension 43 surrounding the tube and a spindle 39 projecting out through the chamber 2 and pivoted to a cam 41 which may be moved by a handle 42 to draw the tube out of driving engagement with the wheels 31. The tube is provided with a conical flange at its upper end and a twisted strip of metal 48 is secured in its bore to divide the bore into two helical passages, up one of which the yarn passes. Moist steam enters the chamber 2 through holes 45 and the yarn 25 is drawn from a supply bobbin 24 by a roller 22 driven from the shaft 6 and passes through a hole 26 in the bottom of a tray 27 to the tube 28; the tray collects water dripping from the hole 29 in which the tube is mounted in the bottom of the chamber 2 and the tray may be filled with water to wet the yarn before it is twisted. The yarn which has been crimped passes from the tube to a guide 50 and to a guide 77 by which it is traversed on a package 52 driven by a drum 56 geared to the shaft 6; guides 77 for diametrically opposite packages are carried from a bar 74 carrying a follower 73 engaging a cam groove 72 in a wheel 71 driven from the shaft 6. Specifications 424,880, 442,073, and 458,595 are referred to.

摘要： 504,401. Unwinding yarns or filaments. POOL, W. Oct. 29, 1937, No. 29634. Drawings to Specification. [Classes 120 (ii) and 120 (iii)] A method of, and apparatus for, unwinding continuous filaments as a plurality of ends from a package. on which they, are wound comprises positively rotating the package about its axis and subjecting each of the ends separately and simultaneously to the action of a fluid stream so as to exert thereon a non- positive pull to draw the ends from the package at a rate permitted by the rate of positive rotation of the package. The fluid stream may be compressed air and the package may be rotated at a constant angular or a constant peripheral speed. Each end of continuous filaments may be converted into a continuous staple fibre product by separating the filaments, e.g. by the fluid stream, cutting from the end successive groups of separated fibres in such a manner that the successive groups overlap and compacting the succession of groups of fibres into a continuous staple fibre product; the filaments may be charged with static electricity to facilitate their separation. The apparatus is substantially the same as that described in Specification 504,399, which is referred to. Specifications 484,190, 489,273, and 504,400 also are referred to.

摘要： 504,399. Yarns etc.; artificial threads; unwinding yarns &c. POOL, W. Oct. 29, 1937, No. 29632. [Classes 120 (ii) and 120 (iii)] [Also in Group IV] A staple fibre yarn or like product of substantially uniform denier is made from a package formed of a bundle of filaments having a denier varying inversely with the diameter at which it is wound on the package, the bundle being withdrawn from the package, which is positively rotated at a uniform angular speed, at a rate varying inversely with the denier of the bundle and the filaments of the bundle being then separated from each other and the ends of the separated filaments cut into groups of separated fibres of predetermined length, which groups are assembled, so that the forward ends of the fibres of each group extend beyond the rearward ends of the fibres of the preceding group, and thereafter compacted to form the coherent staple fibre yarn or like product. The package may be formed by extruding a spinning solution in the form of a bundle of continuous filaments and drawing the filaments from the point of extrusion and winding them on a package support by positively rotating the support at a uniform angular speed ; the wound bundle may be split into two bundles during unwinding and the bundle may be divided into two bundles immediately prior to winding and the two bundles led to the package slightly spaced from each other. As shown in Fig. 1, a bundic 1 drawn from the cabinet 2 is divided into two bundles 4 which are separately guided in slightly spaced relationship on to the package support 8 by guides 5, 6 carried by a traversing shaft 18. The support 8 is removably clamped on a spindle 9 against a driving flange 12 thereon which is driven by a roller 16, the spindle being pivotally secured to an arm 14 swingable about a shaft 15 so that when the package is completed the arm 14 can be raised and the spindle pivoted outwards for the removal of the package ; during removal the filaments delivered by the cabinet are collected on the roller 16, being subsequently moved to a narrow portion 21 and cut off. The wound package 7, Rig. 4, is secured between a pair of flanges 24 for unwinding, the flanges resting on two pairs of driving wheels 25 driven from a shaft 27 which also drives rollers 33 at a speed greater than the rate of delivery of the bundles 4 from the package 7; the bundles from the package pass through guides 32 on a reciprocating bar 40 and by adjusting the rods 38 carrying the guides 32, the arcs of contact made by the filaments with the rollers 33 may be adjusted. The rollers 33 are surfaced with rubber or other material appropriately removed in the electrostatic scries from the material of the filaments as described in Specification 504,400 and from the rollers each bundle is led through a guide tube 41 having an internal nozzle supplied with compressed air through a pipe 43, the air current drawing the filaments from the package 7 are conducting them to a guide member 45 also provided with an internal air nozzle supplied from a pipe 47 with comprossed air which blows the filaments through a diverging nozzle 48 and spreads them out in the form of a flat band ; the band of separated filaments is then cut into successive groups by a cutter 50 in the manner described in Specification 484,190, and the successive groups of separated fibres are drawn into a band 51 by suction so that the forward ends of the fibres of cach group extend beyond the rearward ends of the fibres of the preceding group, the fibres being then compacted into a coherent staple fibre yarn or like product by rubbing bands 53. Specification 489,273 also is referred to.

摘要： 452,797. Winding ribbons &c. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., c/o British Celanese, Ltd., Spondon, near Derby. March 1, 1935, No. 6493. [Class 42 (ii)] [See also Groups IX and XVI] The spindle of the bobbin 18 of an apparatus for winding yarns, threads, ribbons, and the like is supported at one end 12 by the driving wheel 16 engaging a roller 15 on the spindle and at the other end 11 by rolling means 20 while the sideways thrust of the driving wheel 16 is taken by rolling means 22 contacting with the end 12 of the spindle. The spindle ends are disposed in slots 13 in brackets 14 and are supported clear of the sides and bottoms of the slots by the wheel 16 and means 20 ; the means 20 consists of a pair of freely pivoted overlapping discs with the overlapping portions supporting the spindle end 11 and the means 22 consists of a freely pivoted disc having edgewise contact with the spindle end 12. The ends of the spindle are rounded and hardened and the discs may have self-lubricating bushes 31 for the pivots and a number of bobbins may be arranged in side and end relation in the form of a creel on brackets 14 which may be disposed horizontally, vertically or at an inclination ; the brackets may be formed with grooves 24 to house the spindles when the latter are removed from the slots 13 on completion of the winding of a bobbin. In a modification, freely rotatable discs are arranged over the spindle ends to prevent the spindle jumping in the slots 13, the disc at the end 11 of the spindle being disposed vertically above it and the disc at the end 12 being disposed to one side so as to urge the spindle end into contact on the disc 22. In this modification the open ends of the slots 13 are widened and formed with inclined sides and the discs arranged over the spindle ends are mounted in cantilever springs to allow of the easy removal of the bobbin and spindle.
