Title: Improvements in or relating to machines for issuing paper and printed matter in booklet, card, ticket or other form
IPC: G07B5/00
Filed: 1922-12-04
Abstract: 213,636. Bernstein, J. S., Hulbert, L., and Automaticket, Ltd. Dec. 4, 1922. Tickets, issuing and cutting off.-Relates to machines of the kind in which printed matter perforated at regular intervals is delivered from a roll or strip to a guide provided with a spring controlled device for preventing rearward movement of the strip, and is intermittently moved towards a reciprocated cutter for issue from a delivery outlet by an oscillated feed bar; and consists in actuating the feed bar, the cutter, a gripper for the free end of the strip, and an indicator from the same spindle, and in the provision of means for rendering the machine inoperative when (1) a ticket has been severed but not removed from the gripper, and (2) when the device for preventing rearward movement of the strip moves beyond normal position by reason of exhaustion of the strip. The feed bar 13, Fig. 4, is oscillated about a pivot 24 by an eccentric on a shaft 29 rotated by an electric motor. The bar carries at its end a pivoted finger 22 engaging the perforations in a strip in a guide 11. Rearward movement of the strip is prevented by a device 12 pivoted at 61 and pressed by a spring into contact with a strip, which is engages by a sharpened forward end. A holding device for the strip, to prevent a number of tickets being pulled from the machine, comprises a lever having pins 84 engaging the perforations, which pins are released by the arm 13 in its lower position. A cam on the shaft 29 operates a lever 45 reciprocating a cutter severing the ticket along the perforations. A second cam 31, Fig. 3, on the same shaft oscillates an arm 32 actuating a gripper 14 which clamps the ticket against a forked member 41 while it is being severed. Until the ticket is removed the bar 32 cannot descend so that the cam 31 leaves it. The electric circuit for the motor is arranged through insulated conductors carried by the bar and cam, so that when these break contact the cam shaft stops. Pror to this, on the return of the knife a cam thereon has raised a delivery finger 90, Fig. 4, to cause the free end of the ticket to protrude through a delivery orifice so that it may be taken. The cam shaft 29 also operates an indicator 68, Fig. 8, pivoted at 170 and oscillated by an arm 71 engaging an eccentric pin 73 on the shaft. The indicator may read " take it " and "thank you" on its two faces, alternately visible through a window 67. Preferably the indicator is illuminated by a lamp, the circuit of which is broken when the indicator is moving. On the exhaustion of the strip the device 12 moves beyond normal position causing an arm 59, Fig. 3, fixed thereto to arrest the descent of the bar 32, thus stopping the machine. The movement of the arm 59 also breaks the circuit through a lamp to indicate that the ticket supply should be replenished.

Title: Fluid-flow control valve
IPC: F16K31/58
Filed: 1959-09-30
Abstract: 895,880. Valves; nozzles. WELSMAN, B. H. Sept. 30, 1960 [Sept. 30, 1959], No. 33189/59. Classes 69 (3) and 135. A valve comprises a resilient, axially-compressible tubular sleeve 1 being integral with or sealed at its ends to a nozzle 2 and a valve housing 3 respectively, the housing being adapted for connection to a fluidpressure conduit and incorporating a seat 5 co-operating with a closure member 11, 12 carried by the nozzle, the arrangement being such that when the housing is connected to a supply of fluid under pressure, the closure member is held closed by fluid-pressure and may be opened by moving the nozzle towards the housing. The closure member is formed with two balls 11, 12, the ball 11 being secured to a stem 9 which is supported by a spider 7 clamped in the nozzle by a ring 8, the ball 12 being a sliding fit on the stem. In operation, the nozzle 2 is moved towards the housing thereby deforming the resilient sleeve 1 and, via the stem 9, lifting the ball 11 off the larger ball 12 so as to permit a flow through the nozzle via flutes provided in the stem; further movement of the nozzle causes a shoulder 10 on the stem to abut the ball 12 thereby lifting it away from the seat 5 and allowing a greater flow of fluid through the nozzle. The closure member or members, the nozzle and the valve housing may be of metal, plastics material or rubber.

Title: Improvements in chemically-modified starches and their uses
IPC: D06M15/11
Filed: 1949-12-29
Abstract: Starch is treated with vinyl sulphone, the weight of the vinyl sulphone being 0.1 to 50 per cent of that of the starch, to give a water-insoluble product.  Suitable starches are cereal starches, e.g. corn starch, rice starch, and wheat starch; root starches, e.g. potato starch, cassava starch and tapioca starch; starches derived from stems, fruits and seeds; the amylose and amylopectin fractions of raw starch and dextrins.  The reaction is preferably carried out in aqueous solution with or without a wetting agent in the presence of a basic catalyst.  Suitable catalysts are any bases or alkalis which are unreactive with vinyl sulphone, e.g. the phosphates, carbonates and hydroxides of sodium and potassium and alkali earth metal hydroxides and quaternary ammonium hydroxides such as tetraethyl ammonium hydroxide and benzyl trimethyl ammonium hydroxide.  The reaction may also be carried out on a fabric such as cotton or rayon which has been sized with starch, resulting in a stiffening of the fabric which is retained upon subsequent washing and ironing.  In the examples: (a) corn starch is reacted with vinyl sulphone; (b) cotton cloth is treated with a solution containing dextrin, vinyl sulphone and the sodium salt of an alkylated aryl sulphonic acid; (c) a starch paste consisting of corn starch, polyethylene glycol stearate and water is heated, the paste is cooled, treated with vinyl sulphone and sodium hydroxide and subsequently neutralized; (d) soluble starch is dissolved in hot water and vinyl sulphone is added; a catalyst, benzyl trimethyl ammonium hydroxide is added; an insoluble product is obtained.ALSO:Starch is reacted with 0.1 to 50 per cent by weight of vinyl sulphone to form insoluble products which may be used in obtaining permanent sizes on fabrics.  Suitable starches are cereal starches, root starches, starches derived from stems, fruits and seeds, the amylose and amylopectin fractions of raw starches and dextrins.  Preferably the reaction is carried out in aqueous solution, with or without a wetting agent, in the presence of an alkaline or basic catalyst and may be carried out upon a fabric such as cotton or rayon which is sized with starch.  In the examples, cotton cloth is dipped into a solution containing dextrin, vinyl sulphone and a wetting agent; it is treated with caustic soda, neutralized with dilute acetic acid, washed and dried.  The resulting material is stiffer than the original and retains its stiffness after boiling for an hour in soap solution.

Abstract: 506,658. Valve modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WASSELL, H. J. H. Dec. 1, 1937, No. 33249. [Class 40 (v)] In keying circuit arrangements for radio transmitters in which one or more of the high frequency stages is biassed to take a considerable " dead loss while some of the other stages are biassed to " cut-off " during " spaces," auxiliary valves are arranged to provide low resistance paths for the grid currents of the high frequency valves during the " mark " condition. Stages 2, 3 and 4 of a radio transmitter are biassed to " cut-off " during " spaces " by connection at 20 to the potentiometer 17 in the anode circuit of the keying valve 10 which is then conductive. Stage 5 is biassed to take a " dead-loss " by connection to point 23 on potentiometer 17. Auxiliary valves 7, 12 with their anodes connected to earth and cathodes connected to points 20, 23 have their grids connected to points 18, 22, on the potentiometer, so chosen that they are nonconducting in the " space " condition shown. During " marking " the key 15 is closed and the anode current of valve 10 is cut off by the negative bias 14 ; valves 7, 12 are then conducting, since their grids and cathodes are at approximately the same potential, and provide low resistance paths for the grid currents of stages 2, 3, 4, and 5.

Title: Improvements relating to synchronizing clutch devices
IPC: F16D23/06
Filed: 1955-11-22
Abstract: 786,828. Positive clutches. DAIMLERBENZ AKT.-GES. Nov. 22, 1955 [Nov. 23, 1954], No. 33438/55. Class 80 (2). In a claw clutch combination wherein an internally-toothed sleeve 18 slidably keyed on a hub 15 is engageable with claw teeth 13 or 14 on wheels 10 or 11 to couple one or other wheel to the driven shaft 12 of a motor vehicle changespeed gear, and synchronizing rings 19 provided with baulking teeth 21 are coupled to the hub 15 and engage conical friction surfaces on rings 25 coupled to the wheels 10, 11, the friction rings 25 are coupled to their respective wheels 10, 11 through springs allowing limited relative rotation. To provide the spring connection, dogs 29 on the rings 25 engage between dogs on the wheels 10, 11 with angular clearance and springs, Fig. 2 (not shown), hold the dogs 29 in a central position. Three grooves 40, Fig. 3, in the hub 15 house slidable pieces 37 connected by spring-loaded balls 38 with the slidable sleeve 18, the pieces 37 engaging projections 41 on the synchronizing rings 19. The projections 41 have angular clearance in the grooves 40 and preferably this clearance, and the clearance for the dogs 29, correspond to half the pitch of the teeth 13, 17 and 21. If the sleeve 18 is moved to clutch the hub 15 to the rotating wheel 10, the rings 19, 25 are first pressed together by the pieces 37 and ball connections 38 and the ring 19 is frictionally rotated relatively to the hub 15 to take up the clearance in the grooves 40, this rotation causing the teeth 21 to baulk further axial movement of the teeth 17, i.e. of the sleeve 18. When the shaft 12 reaches the speed of the wheel 10, the torque between the ring 19 and hub 15 is reduced so that under axial pressure on the sleeve 18 the pointed teeth 17 turn the teeth 21 out of baulking position. If the friction between the rings 19, 25 is too great to allow relative rotation under this axial pressure, the springs locating the dogs 29 yield to allow both rings 19 and 25 to turn relatively to the wheel 10 until the teeth 17 can move through the teeth 21 and engage the claw teeth 13. The ring 25 is subsequently returned to its central position by the aforementioned springs, which may be associated with stops to limit their extension substantially beyond a centre position and so prevent oscillation of the ring 25.
