Title: Improvements in or relating to push-pull modulators
IPC: H03C1/58
Filed: 1936-12-24
Abstract: 471,299. Modulating circuits. CHAPPLE, W. J. C. (Siemens & Halske Akt.- Ges.) Dec. 24, 1936, No. 35416. [Class 40 (v)] In a push - pull modulator of the type comprising a bridge network of non-linear elements, means are provided for injecting into the output circuit a carrier frequency current the amplitude and phase of which are adjusted to eliminate from the output circuit the residue of the carrier frequency or signal frequency or both, due to the differing characteristics of the non-linear elements. As shown, the bridge 1, 2, 3, 4 of non-linear elements is supplied with signal frequency from the transformer U1 and carrier frequency from the transformer U3, the modulated output being taken from the transformer U2. Connected across the carrier source U3 is a bridge comprising a variable resistance arm r1 a capacity-shunted resistance arm r2, c and a diagonal resistance r3, a variable part of which is included in series with the modulator output circuit. The amplitude of the carrier frequency thus injected into the modulator output is adjusted by variation of r1 and the tapping on r3, and its phase by variation of c. In a modification, Fig. 5 (not shown), the bridge r1 ... r3 is fed from a resistance connected in series with the carrier source, and the resistance may vary with current or temperature to compensate for variations in the characteristics of the modulator, due to current or temperature changes.

Title: Improvements in or relating to machines for causing relative movement between shoes and lasts
IPC: A43D21/02
Filed: 1938-12-06
Abstract: 522,124. Removing shoes from lasts. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Dec. 6, 1938, No. 35455. Addition to 474,451. [Class 17 (i)] The machine described in the parent Specification is modified by the provision of a latch to prevent the pad rising until it has engaged the shoe, the provision of a thrust rod which under the action of a compression spring yieldingly urges the tool-carrying L-shaped arms forwards and the alternative use of shoe contacting tool of fibre engaging the rear edge of the upper. Instead of the rubber pad described in the parent Specification, a plate of fibre may contact with the shoe at its rear edge. The plate is mounted on a slide having slight freedom in all horizontal directions in the carrier 56. It is centralized by spring plungers 72 and urged forwardly by a lever 66, one arm 68 of which co-operates with a step on the carrier to function as a latch. When by contact of the tool with the shoe the latch is swung anti-clockwise, the arm 68 is swung clear of the stop and the tool rises. A rod 118 urged upwardly by a spring 119 assists the swing of the L-shaped arms 78. The carrier 56 swings about its pivot 76 with an arm having grooves 152 co-operating with a spring plunger, to hold the tool up to clear the last on its return to starting position.

Title: Improvements in or relating to filters
IPC: B01D29/48
Filed: 1935-12-23
Abstract: 459,409. Filtering gases. KNECHT, A., 48, Haldenstrasse, Stuttgart, Germany. Dec. 23, 1935, No. 35512. Convention date, Dec. 22, 1934. [Class 8 (ii)] [See also Group I] A cylindrical or conical filter element formed by winding wire of circular cross-section is arranged for filtration inward, and a brush rotatable about the axis of the filter relatively to the filter acts upon the outside of the latter. As shown in Fig. 1 the filter element is formed by coiling wire 4 on a perforated cylinder 3, the correct spacing of the convolutions being ensured by winding the wire on soft strips of lead foil or other plastic material arranged along the wall of the cylinder. The cylinder is fixed on a rotatable shaft 7 and a brush 9 is rotated from the shaft by gear wheels 10, 11, 12. The casing 2 has an inlet 1 and the filtrate is discharged through a trunnion 6. The brush may be formed of bristles or of felt rings. In the modification shown in Fig. 3, two brushes are mounted on a rotatable yoke 15 and the filter element is stationary. Fig. 5 shows a further modification in which the filter is formed of wire wound over the fluted exterior of an impermeable cylinder 3. The liquid is supplied by a pipe 1 to the interior of the cylinder, where impurities settle, and passes upward to the outside of the element, filters into the flutes and is discharged through an outlet pipe 6. The matter settling both inside and outside the filter is discharged on removal of a screw plug 8. These filters are especially applicable on motor vehicles the movement for brushing the filter being derived from a moving part such as a brake or clutch-pedal lever or the steering-column.

Title: Machine for cutting and stacking a plurality of lengths of cloth or the like web materials
IPC: D06H7/02
Filed: 1929-11-23
Abstract: 344,010. Feeding webs. GADBOIS, J. E., Springfield, Massachusetts, U.S.A. Nov. 23, 1929, No. 35877. [Class 100 (i).] Delivery apparatus for sheets.-In a machine for cutting and stacking lengths of cloth, mechanism operated from the feed of the material stops the feed, disengages the feed mechanism from the material, and elevates the feed mechanism in order to allow the cut pieces to be stacked on a stationary cutting table. The web 3 is fed from a roll 4 by rollers 5 driven by sprocket chains from a shaft 11. The material is fed over a fixed table 12 by grippers which clamp one edge of the web and by a transverse clamp bar carrying pins. The grippers and the clamp bar are carried on chains engaging sprockets driven from shafts 28, 11. The clamps are opened by a fixed cam 90, not shown, at the start of the feed and are released by a bar 46 operated by levers 50 from a rack 58 engaging a gear 59 on a shaft 60. The chain carrying the grippers is mounted on guides moved vertically by racks 63 engaged by sprocket gears on shafts 65. The shaft 65 may be rotated by hand or through pawl mechanism. In operation, a hand-lever 86 is moved to clutch the shaft 28 to the shaft 11. The chains 16 are then driven and the clips 19 successively engage the fixed cam 90 and are opened to engage the web, which has previously been placed on the pins 24 of the clamp. At the end of the feed movement the clamp-bar strikes a lever 42 which, through a rod 44, throws out the clutch 81 and stops the feed, and throws in a clutch 82 operating a rack 58 to release the clips by depressing the bars 46. The lug 74 through a bar 72 actuates the ratchet wheel 70 to elevate the feed mechanism. The sprocket 78 is then moved into neutral position to prevent feed and elevating movements by a rod 87 operated from the shaft 60. The cloth is severed by a hand-operated guillotine blade 86, not shown, co-operating with a plate 35.

Title: Improvements in or relating to clutches
IPC: F16D13/08
Filed: 1963-09-12
Abstract: 970,153. Torque limiting couplings. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 12, 1963 [Sept. 14, 1962], No. 35927/63. Headings F2C and F2U. A coil spring coupling in a magnetic tape recording apparatus, provides either a low torque drag on the unwinding spool shaft for maintaining tape tension during recording and playback, or a high torque drive to the same shaft for rapid rewind, and comprises a coupling coil spring 3 in frictional engagement with both a head 8, of an arbor 6 fast with a driving shaft 1, and a larger diameter head 12, fast with a driven shaft 2, one end 29 of the spring 3 being connected through a sleeve 25 to a case 4 which is torsionally loaded by an auxiliary spring 30 to tension the spring 3, the sleeve 25 being circumferentially adjustable relative to the case to vary the frictional grip of the spring 3 on the heads 8, 12, the other end 16 of the spring 3 being connected to a slot 18 of a disc 17 which is freely mounted on a shoulder 20 of the arbor 6, such disc 17 being positively clutched to the arbor, by a sleeve 34 slidably keyed on the arbor 6 and controlled by a solenoid-operated lever 42. The arrangement provides the low torque, when the sleeve 34 is in its disengaged position, the drive being solely through the frictional grip of the spring 3 on both the heads 8, 12, torque being limited by the grip of the spring 3 on the smaller head 8; whilst the higher torque is provided by energizing the solenoid to operate the clutch ring 34 to positively clutch together the disc 17 and the driving arbor 6 whereby the spring 3 is positively driven by its end 16, so that torque is now limited by the grip of the spring 3 on the larger head 12. The auxiliary spring 30 is fitted at one end to the case 4 and at the other end to the slot 18 of the disc 17, the spring 30 being oppositely wound relative to the spring 3 which may thus be pre-loaded to a value variable by locking the sleeve 25 in any required position relative the case 4 by a grub screw. Sealing rings 21-24 are provided at each end of the assembly. In a modification, the clutch control member 17 may alternatively be positioned on the driven shaft side with the arbor head diameters and springs rearranged accordingly.

Title: Improvements in or relating to transfer apparatus
Inventor: MERRELL RONALD WALTER
IPC: B65G47/90
Filed: 1966-08-11
Abstract: 1,133,597. Conveyers; grippers. GENERAL ELECTRIC CO. Ltd. 27 Sept., 1967 [11 Aug., 1966], No. 36060/66. Headings B8A and B8H. Bricks 5 on an endless conveyer 4 are (in response to a signal initiated by a sensing device, not shown), engaged between gripper pads 16, 16, on an arm 2 carried by a rotary head 1, and are carried round to be released on one of endless conveyers 41, 42. The head 1 is rotated unidirectionally by the action of two pneumatic jacks (6), (7) (Figs. 2 and 3, not shown). The jacks are controlled by electrically controlled pneumatic valves (12), (13). A brake drum (31) has indexing notches (32) engagable by a member (35) of a piston-cylinder unit (36) controlled by an electric valve mechanism (38). A similar mechanism (39) controls piston operated brake shoes. One of the jaws 16 is carried by a member 17 which is pivotable into brickgripping position by the action of a pneumatic piston cylinder unit 19. A pivot connection 25 of the latter to the jaw member 17 is mounted eccentrically between members 26 disposed in respective keyhole shaped recesses of cheeks 29 rigid with the arm 2. The members 26 are each formed with a pair of flats which are adapted to be aligned with the narrow section of the keyhole shaped recesses 26. This arrangement provides a degree of linear movement of the member 17 relative to the fixed jaw 16 before pivotal movement takes place, and vice versa. The member 17 may be telescopically adjustable relative to the arm 2 to enable the apparatus to deal with bricks of different sizes. The sensing device may comprise jets of air or light beams directed across the path of the bricks, or mechanical means engaged by the latter. A sizing device 40 detects bricks of incorrect dimensions or bricks stuck together, and may be combined with the sensing device. In operation, a brick 5 rejected by the sizing device 40 is not picked up by an arm 2 but is allowed to proceed on the conveyer 4. Otherwise the bricks are picked up in turn by successive arms 2 and are released in alternate successions of two on the conveyers 41, 42. A guard 43 rises to a raised position during each step of the head 1 while two bricks are successively deposited on the conveyer 41. Then the guard remains retracted and a guard 44 similarly rises as each of a further succession of two bricks is deposited on the conveyer 42.
Patent GB-416923-A (GB)
Title: Improvements in engine starter controls
IPC: B60K26/00
Filed: 1932-12-20
Abstract: 416,923. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Dec. 20, 1932, No. 36114. Convention date, Dec. 21, 1931. [Class 38 (iv).] In an engine starting-mechanism in which operation of the starter is effected through a connection to a driver-actuated control member, the connection is broken only on the returnof the control member to its released position after the commencement of rotation of the engine, and remains broken so long as the engine continues to rotate. As shown in Fig. 1, the control member is the accelerator pedal 7, which is pivotally connected to a rod 8 having an adjustable abutment 9 for engagement with a lever 10 connected by a link 12 to the throttle valve. The pedal 7 actuates the switch 4 of an electric starting-motor 5 through a lever 16, which is pivotally connected to a member 13 engaged by an enlargement 14 on the rod 8. A shoulder on the enlargement 14 is normally engaged by a latch member 21 in a cylinder 22 on the member 13. The cylinder 22 is connected by a conduit 38 to the inlet 34 of a pump comprising a diaphragm 26 actuated by an engine-driven cam 31 through a lever 27. When the engine is running either forwards or backwards, the pump is actuated and the latch 21 is lifted by suction, so that the enlargement 14 slides freely in the sleeve 13 without actuating the switch 4. To prevent the premature disabling of this connection during the starting operation, a slide valve 39 in the conduit 38 has a plunger 41 pivoted at 42 to the cylinder 22 ; movement of the sleeve 13 to close the switch 4 causes the valve 39 to cut off the suction conduit 38 from the cylinder 22 until the pedal 7 has been released. To prevent the re-establishment of the connection between the pedal 7 and switch 4 until a predetermined time after the engine has stopped, the pump inlet 34 is provided with an adjustable bleeder valve 48. If the latch is to be disengaged by pressure instead of suction, the conduit 38 is connected to the pump outlet 37. In a modification, Fig. 2, the cylinder 22 is continuously connected to the pump, but a port 45 in the side of the cylinder 22 is normally closed by a switch lever 46 pivoted to the cylinder 22 at 47 ; the port is uncovered by movement of the sleeve 13 to close the switch, so that suction in the pump conduit is then ineffective to raise the latch 21. In a further modification, Fig. 4, the latch 49 is controlled by pressure from the lubricant pump through a conduit 58 provided with a cock 62 connected by a link 64 to an arm 65 on the throttle lever 10, in order to cut off the fluid pressure when the switch 4 is closed. When the engine is running, the fluid pressure depresses the latch 49 by means of an elastic bellows 55, and the rod 8 then moves freely in a port 54 in the latch without actuating the switch lever 16.

Abstract: 405,097. Curve-drawing instruments. FARQUHARSON, W. E., 35, Shrewsbury Road, Birkenhead, Cheshire. Dec. 21, 1932, No. 36158. [Class 97 (iii).] In a toy designing-machine, a table is rotatably mounted on a base and driven by a drum or disc and an oscillatory lever pivoted on the base intermediate its ends has at one end a holder for a marking device for tracing a design on paper on the rotary table and at the other end an aperture engaging an eccentrically mounted pin on the driving drum or on an auxiliary driven drum. In the form shown, the rotary table 4, on which paper may be fixed by studs 8, is driven by a rubber or other band 6, kept taut by an adjustable jockey pulley 7, from the drum 5. The lever 11, having slots 15, 15a, 15b and holes 16, 16a, 16b, is pivoted to a bracket 12 on the base 1 by a detachable pin 14. A pencil holder 19 is adjustably mounted in the slot 15b and the slot 15a is engaged by a pin formed by the crank handle 9 which may be inserted in one of a series of eccentric sockets in the drum 5. Alternatively the crank handle 9 may engage one of the holes 16 in the lever 11 and the pin 14 the slot 15a, the pencil carrier 19 then being mounted in the slot 15.
Patent GB-896880-A (GB)
Title: Wet treatment apparatus for textiles
IPC: D06B3/18
Filed: 1958-11-11
Abstract: <FORM:0896880/IV (c)/1> Textiles are wet-treated in apparatus comprising a bath in which a perforated drum is mounted for horizontal rotation, means to rotate the drum, and a pair of rollers, at least one of which is driven, the pair of rollers being mounted above the bath in an axially inclined position.  As shown, a substantially rectangular bath 5 contains a liquid 6 which may consist of a rinsing, washing or dyeing medium.  A drum 1 mounted on a shaft 8 is immersed in liquid 6 and is journalled at one end to a vertical wall 9 of the bath 5.  At its opposite end the drum is mounted for rotation on a pump housing 11 which projects into the bath from the opposite vertical wall 12.  A circulation pump 13 mounted within the housing 11 has a propeller shaft 15 which extends through walls 12 and is driven by conventional means (not shown). The periphery of drum 1 has perforations 16 through which liquid 6 flows, when agitated by pump 13, thus causing rotation of the drum. A pair of inclined rollers 3, 4 are mounted above the bath 5, lower roller 3 functioning as a guide roller for textile material to be treated and roller 4 acting in conjunction with roller 3 as a squeeze roller.  Both rollers have associated driving means (not shown). Strip textile material 21 is wound around drum 1 and passes between rollers 3, 4.  In operation sufficient suction is caused by the passage of liquid to the interior of the drum 1 to result in adherence of textile material 21 to the periphery of the drum. Squeezing of the textile material between rollers 3, 4 removes treating liquid therefrom and inclination of the rollers permits easy return of the liquid to the bath.  Roller 4 is preferably spring loaded and conventional provision is made to adjust the pressure between rollers 3, 4 in accordance with the thickness of the textile material 21.  Elimination of the suction effect over that part of the periphery of the drum near the surface of the liquid 6 is effected by provision of a shutter 2 mounted arcuately and non-rotationally in the upper interior of the drum.  Thus as p  textile material 21 rises in the bath 5 to a position near the surface of liquid 6, the suction effect is broken due to the interposition of shutter 2 and the textile material passes upwardly to rollers 3, 4.
