Title: Method for the Manufacture of Flexible Sheet Materials
Inventor: CLARKE DENNIS IVON
IPC: D04H13/00
Filed: 1966-04-06
Abstract: 1,176,161. Laminates. DUNLOP CO. Ltd. 5 April, 1967 [6 April, 1966], No. 15413/66. Heading B5N. [Also in Division B2] A method of making flexible sheet material comprises applying a binder to one surface of an assembly of a compressed sheet of a cellular material adhered to a fibrous or cellular sheet material and allowing the binder to permeate and impregnate the assembly and heating the impregnated assembly to set the binder. The term "compressed sheet" is directed to a sheet which has been compressed under conditions of heat and pressure such that the material is retained in the compressed form when compressive forces are removed; said compression being effected prior, during or after adhesion to the other sheet. Compression may be effected in the presence of adhesives, e.g. natural or synthetic rubbers, polyester resins, epoxy resins, polyvinyl chloride or polyurethanes, the adhesives preferably being applied in a liquid medium. Specified cellular materials which may be reticulated, may be formed in situ and which may contain fibres, e.g. polyester, polyamide, cotton or wool fibres, are natural and synthetic rubbers, polyvinyl chloride, polyethylene, polypropylene and polyurethanes. Specified fibrous sheet materials are bonded, crimped, fibrous felts, non-bonded, crimped fibrous felts and knitted or woven fabrics, e.g. of cotton, rayon, nylon, polyethylene terephthalate or acrylic fibres; composite non-woven webs may be used. Adhesion between the layers of the assembly may be effected by an adhesive, e.g. a natural rubber latex, a polychloroprene latex, an ethylene-vinyl acetate copolymer, a latex of a graft copolymer of rubber and poly-(methylmethacrylate), neoprene, a polyurethane or a carboxylated styrene - butadiene copolymer latex, by an interlayer of an open-mesh fabric, e.g. cotton scrim coated with an adhesive or by softening the surface of the compressed sheet before bonding, e.g. by the application of heat or a solvent. Specified binders are natural and synthetic rubbers, e.g. copolymers of butadiene with styrene or acrylonitrile, polyvinyl chloride, polyurethanes and ethylene-vinyl acetate copolymers. The binder is preferably distributed differentially through the assembly, e.g. by heating one surface of the assembly differentially with respect to the other surface. In a preferred embodiment, a compressed sheet of cellular material is adhered to each surface of a sheet of cellular or fibrous material. The surfaces of the flexible sheet material may be embossed and/or surface finished with a polyacrylate or polyurethane. The products of the process of the invention may be used as a substitute for leather, e.g. in the manufacture of shoe uppers, shoe linings, upholstery, clothing and handbags.

Title: Voltage Regulators
Inventor: WILLIAMS MALCOLM
IPC: H02J7/24
Filed: 1966-04-07
Abstract: 1,184,891. Automatic voltage control. JOSEPH LUCAS (INDUSTRIES) Ltd. May 25, 1967 [April 7, 1966], No.15540/66. Heading G3R. A voltage regulator includes a sensing circuit constituted by a voltage divider 13, 14 and a Zener diode 15 for detecting the output voltage of a generator supplying output lines 11, 12; an amplifier comprising transistors 16, 18 for controlling a switching transistor 21 connected in series with the generator field winding 22; and a delay circuit associated with the amplifier in such a way that the amplifier switches transistor 18 on and off with a mark-space ratio controlled by the sensing circuit, thereby controlling the output voltage of the generator, the delay circuit comprising a capacitor 24 connected across the base and collector of transistor 16. In operation, when the output voltage rises above the predetermined value Zener diode 15 conducts and transistor 16 starts to turn on, but the actual turn on is delayed for a certain period because of the action of the capacitor 24 which tends to maintain constant the collector voltage of transistor 16; during this delay period the output rises still further so that when transistor 16 does switch on it does so completely. The converse effects take place when the output voltage falls, so that the switching action of transistor 16, and thus that of transistors 18 and 21, takes place very quickly and the usual switching feedback circuit is not required.

Title: Improvements in or relating to radio signalling systems
Inventor: BRAY WILLIAM JOHN
IPC: H04L1/06
Filed: 1949-06-13
Abstract: 695,353. Automatic phase control systems. POSTMASTER GENERAL. Dec. 1, 1950 [June 13, 1949]. No. 15723/49. Class 38 (iv). [Also in Group XL (c)] A received signal bandwidth is divided into a plurality of sub-channels by filters 12 and a further filter 15 of each sub-channel selects a pilot signal concurrently and separately transmitted in each sub-channel and uses it retroactively to effect automatic gain or both gain and phase control of the signals in each subchannel so that amplitude or both amplitude and phase distortion due to multi-path delay effects in reception from the ionosphere is compensated in the combined output. The system permits increased signalling speed when applied to a high-speed telegraph signal of bandwidth 1000 c/s. divided into ten channels of 100 c/s. bandwidth. The pilot signals are separately transmitted in and may correspond to the mid-frequencies of the sub-channels. The pilot frequencies may be amplified and applied, together with a local oscillator frequency in each sub-channel tuned to a harmonic of the pilot frequency, to a phase discriminator 18, the D.C. output of which maintains the phase of the pilot frequency in the sub-channel constant, and the pilot frequency amplified at 16 and rectified at 17 also applies A.G.C. to each sub-channel amplifier 14. In the combined output of the sub-channels the amplitude/ frequency ratio is constant and the phase/ frequency relation linear. The system may be applied to radio frequencies, amplitude, frequency or pulse modulated, or to the received frequencies of a single side-band receiver after transposing them to an audio-frequency range.

Artificial silk, fabrics containing ; yarns specially treated, fabrics with.-The application of a fugitive and temporary colour to dry-spun threads of cellulose esters, ethers, &c. for the purpose of distinguishing threads of different nature is effected either upon the elementary filaments before union into threads or upon the moving threads before or during reeling. The colours employed may be organic or inorganic, in solution, suspension, or emulsion, or as pastes, jellies, or solids, and may be applied to the threads by passing them over rollers, pads, or impregnated surfaces, by passage through baths, or by atomizing, spraying, or rubbing; these operations may be performed within or without the spinning cells. Further differentiation may be obtained by colouring a given thread in portions only, or by applying different colours to different portions of one thread, or by colouring only some of the elementary filaments, the others being left uncoloured or coloured differently.
