Title: Method of making paper products suitable as substitutes for textile materials
IPC: A41D31/00
Filed: 1964-10-09
Abstract: A textile-like material is made by impregnating an extensible paper with a plastisol or organosol of a vinyl chloride polymer or copolymer and a plasticizer therefor, and heating to dissolve or swell the resin in the plasticizer.  The paper may be a creped tissue paper, and may contain synthetic fibres, e.g. of nylon or glass, as well as cellulose fibres.  Wet-strength-improving agents may be added to it during its manufacture.  The polymer may be polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate.  Polyvinyl acetate may also be present.  The plasticizer may be dioctyl phthalate, dibutyl phthalate, dioctyl adipate, or a derivative of lauric, oleic or stearic acid.  The product may be made fireproof by the use of a self-extinguishing plasticizer, e.g. tricresyl phosphate.  The plastisol or organosol may also include a stabilizer, e.g. calcium stearate, dibutyltin dilaurate or barium/cadmium laurate and triphenyl phosphite, a dispersing agent, e.g. an alkyl polyglycol ether or sorbitan monooleate, a dye or pigment, e.g. carbon black or titanium white, a viscosity-reducing agent, e.g. white spirit or methanol, and aluminium oxide.  The surface torsion may be reduced by adding a silicone oil to the plastisol or organosol.  The product is porous and has sufficient wet-strength to be washable.  It can be seamed by the application of heat.

Title: Stuffer box crimping apparatus for crimping yarns
IPC: D02G1/12
Filed: 1971-09-09
Abstract: 1379041 Crimping yarns PLATT INTERNATIONAL Ltd 5 Sept 1972 [9 Sept 1971] 42150/71 Heading D1F A stuffer box crimping apparatus comprises ultrasonic sensing means which detects unacceptable change in the position of a plug of crimped yarn in the stuffer chamber and generates a corresponding control signal whereby the speed of feed into or withdrawal of yarn from the chamber is correctively adjusted. In the crimper shown in Fig. 1, when the head of the plug is below an emitter 23 and detector 27 both the beams from electrically actuated, ultrasonic pressure wave emitters 22 and 23 strike detectors 26 and 27 and produce output signals which are applied to a circuit 30 to operate a speed control unit 31 to reduce the speed of delivery rollers 28, 29. As the plug then rises and the beams are successively interrupted the collective change in output signal from the detectors operates the unit 31 to increase the speed of delivery roller 28, 29. Subsequent fall in the level of the plug in the passage 8 beyond both emitters results in a corrective speed reduction. Alternatively the speed control may be applied to the crimping rollers 12 and 13. In another crimper, Fig. 2 (not shown) a single ultrasonic beam when interrupted by the plug causes a detector to generate a signal which is proportional to the fibre density of the plug and initiate corrective speed control. In the apparatus of Fig. 3, the aligned emitter 22 and detector 26 are carried on a reciprocating carriage 64 so that the the control signal from detector 26 is proportional to the average fibre density of a ply of yarn scanned by the ultrasonic beam along a length determined by slots 60, 62, in plates 6 and 7 forming sides of the stuffing chamber.

Title: Phase-controlled rectifiers
Inventor: ROSS JAMES ARTHUR
IPC: H02M7/162
Filed: 1966-09-22
Abstract: 1,103,980. Rectifying. LTV LING ALTEC Inc. 22 Sept., 1966, No. 42415/66. Heading H2F. A rectifying circuit using controlled rectifiers such as thyristors has its output voltage maintained constant for varying input voltage by firing the controlled rectifiers at the instant when a voltage proportional to the input voltage falls below a direct reference voltage. The invention is described with reference to a three-phase thyristor bridge (Fig. 1, not shown). A first control circuit (Fig. 5, not shown) receives both phase and line voltages to obtain the voltage proportional to the input voltage for each phase. This is compared with a common reference voltage and used to fire a silicon controlled switch in the control circuit of the associated thyristor. An alternative control circuit has for each phase a Schmitt trigger (Fig. 6, not shown) which is switched by the difference of the two control voltages to give thyristor firing signals through a pulse transformer (70).

Patent GB-428875-A (GB)
Abstract: 428,875. Printing lenticular films. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Nov. 25, 1933, No. 33050. Convention date, Nov. 25, 1932. [Class 98 (ii)] Lenticular films are copied, by contact printing, without lateral inversion, by arranging original and copy films with their embossed surfaces facing the light source and with an interposed " stencil film " having opaque and transparent areas so disposed that the light rays of a partial colour picture emanating from the original follow the direction of the trace of the rays of the corresponding partial colour picture of the print during projection. The " stencil film " may be a lenticular film produced in the manner described in Specification 412,021 ; or it may consist of a smooth fihn having opaque and transparent zones on both surfaces, produced by projecting a line screen on one surface on to an emulsion on the other surface by a punctiform source of light arranged in a position corresponding to that of the optical centre of the corresponding filter strip used in projecting the print. As shown in Fig. 1, the original film C is copied on to the film F through an interposed stencil film H by diffused light projected through the appropriate zone of the filter or diaphragm A which is of the same breadth and is arranged at the same distance from the film C as that used for exposure. To avoid streakiness, a layer I of transparent material is interposed between the film C and stencil H. Multiple printing may be avoided by the use of a stencil film having zones dyed in the appropriate colours in conjunction with a multicolour filter. A multi-colour line screen original may be employed in place of a lenticular original, the film being placed with its emulsion in contact with the stencil film and a filter corresponding to that partial colour sensation to be printed being interposed between the light source and the film. Streakiness may also be avoided by relative inclination of the embossings of the original and stencil or copy films. Fig. 5 shows a printing machine in which original and copy films are fed past stepped diaphragms BR, BG, BB, and are printed through an interposed stencil film H having three sections corresponding to the three partial colour sensations. For line-screen originals appropriate colour filters are inserted, e.g. at M.

Abstract: 1362414 Testing ordnance RHEINMETALL GmbH 17 Sept 1971 [5 Dec 1970] 43407/71 Heading F3C [Also in Division F2] An impulse transmitter for testing pieces of ordnance comprises a housing 1, Fig. 3, a cylindrical member 6 which is located in the housing 1 and receives a cartridge 9 therein, and a piston 10 which is actuable by the gases of the propellant charge of the cartridge 9 to move a gun barrel R in the recoil direction of the gun. The member 6 has outlet apertures 11 which connect to atmosphere, via a chamber 12 and a valve 26, when the piston 10 has been actuated by said gases. The volume of the chamber 12 is at least ten times the stroke volume of the piston to damp the firing blast of the cartridge. In use the barrel R is positioned over a centring cone 15, which, along with a pressure plate 16 and an elastic plate 14, is clamped to a pressure plate 13 by a tie-rod 17, the pressure plate 13 being carried by the piston 10. The transmitter, which is mounted by wheels 2 on a rail track, is urged towards the barrel R by a recuperator 5 having one end connected to the housing 1 and the other end connected to the rail track. The cartridge 9 is located in a chamber 8 of the member 6 and is detonated by a device 31 in a breechblock 7. The piston moves against the action of a recuperator spring 25 and the pressure plate 16 pushes the barrel R in the recoil direction until the resultant of all the forces on the impulse transmitter acting on the piston imparts a braking retardation thereto. The outlet apertures are uncovered and the gases escape to atmosphere via the chamber 12 and the valve 26. The piston is then returned to its initial position by the springs 25 and the transmitter is returned to its initial position by a recoil brake 4 and the recuperator 5. The braking retardation is by a device comprising an annular chamber 19b formed in a housing 19 which surrounds the piston 10, and a member 21 which is mounted on the piston. The chamber 19b and a chamber 23 formed in the piston are connected by a passage 20 and have brake fluid therein. The piston has a bore 10a having a floating piston 22 therein which is urged by pressurized gas from a chamber 24 in the piston. The chamber 19b, being tapered, is engaged by the member 21 when the piston has completed its working stroke. The braking device may be replaced by hydraulic buffer brakes 32, Fig. 5, and the recuperator spring 25, Fig. 3, may be replaced by a recuperator 33, Fig. 5, the brakes 32 and the recuperator 33 being secured to the cylinder 6 and to the pressure plate 13.
