Title: Analog to digital converter
IPC: H03M1/34
Filed: 1967-10-16
Abstract: An analogue-to-digital converter comprises a body 1, Fig. 6, of semi-conductive material exhibiting high field instability effects, the resistance of the conducting cross-sectional area being increased along the major axis, there being electrodes 2, 3 between which is applied a potential difference to produce a steady electric field which is normally less than the instability threshold, the field being increased in response to an input signal to a value exceeding the instability threshold value, at least locally within the body, to form a high field domain within the body which propagates therealong before extinguishing a distance determined by the magnitude of the input signal. Pulse generating means are provided which when encountered by the propagating high field domain produces a series of output pulses. It is arranged that the last n of these pulses before the high field domain extinguishes are in the form of a digital pattern representing the magnitude of the input signal. The output pulses may be produced by grooves 4 air-abraded or etched into the body. Two sets 'of grooves may be made, Fig. 10, to form a coded pattern of "1"s and "0"s. Alternatively the regions of different resistivity may be made by doping alternate areas 8, 9, 10 etc., Fig. 7. The intermediate areas 7 all have the same value. Extra electrodes 15, Fig. 8, may be provided insulated from the body by layer 22. The high field domain takes the form of sharp current pulses and it is sensed capacitively by the electrodes 15 in turn. To obtain the last n digits the output from the converter 16, Fig. 11 is applied via a delay 17 to a gate 18. The delay stores the last n digits, the gate being operated when the high field domain extinguishes to pass them to the output.

Title: Process for liquefaction of natural gas and transportation by marine vessel
IPC: F25J1/02
Filed: 1967-10-31
Abstract: Liquefaction of compressed natural gas prior to transport in a heat-insulated container from a field site to a market site where it is re-vaporized in heat exchange with a gaseous refrigerant comprising mostly nitrogen undergoing liquefaction is effected by heat exchange in a path 34, Fig. 1, with liquid nitrogen in a path 24 and having been transported from the market site in containers previously occupied by L.N.G. the liquid nitrogen prior to passage through path 24 being pressurized by a pump 18 and the nitrogen gas leaving pass 24 being work expanded in a turbine 26 and passed through a further path 29 thereby serving to assist liquefaction of feed natural gas. At the market site L.N.G. is withdrawn from the containers and is vaporized by passage through a path 46, Fig. 2, of a heat exchanger 44 in indirect countercurrent flow in a path 50 of compressed gaseous nitrogen which is partly liquefied, expanded to about atmospheric pressure into a phase separator 62 the liquid nitrogen being withdrawn through a line 64 leading to a transport container 16 whilst cold gaseous nitrogen after recovery of cold in an exchanger 56 is recompressed at 58 and returned to the inlet 48 of path 50. In a modification the compressed natural gas having been liquefied at the field site is expanded in a turbine which drives the pump for pressurizing the liquid nitrogen, and the nitrogen expansion turbine drives the compressor for the feed natural gas and at the market site L.N.G. is split into a first stream which is vaporized by heat exchange with gaseous nitrogen and then compressed and discharged into a product line, and into a second stream which is pressurized by a pump, vaporized, turbine expanded and added to the first stream in the product line the turbine being used to drive the compressor.

Title: Process of reaction organic polyisocyanate with alkali metal silicate solution
IPC: C04B28/00
Filed: 1968-05-11
Abstract: Silicious products are prepared by reacting an aqueous solution of an alkali metal silicate with an organic isocyanate or isothiocyanate. The isocyanate or isothiocyanate is preferably a polyisocyanate or polyisothiocyanate and more preferably is 4,41-diphenylmethane diisocyanate or a tolylene diisocyanate.

The reaction may be carried out in the presence of a catalyst, e.g. a tertiary amine or an organometallic compound. The reaction conditions may be such as to produce cellular products by the evolution of carbon dioxide. Conventional blowing agents and surfactants may be added to the reaction mixture to assist in the foam production. Polyols may also be added to the reaction mixture, as may polymers and fillers in fibrous or particulate form. The filler materials may be sand, alumina, alumino-silicates, magnesia, metal fibres, asbestos, glass fibre, rock wool, aluminosilicate fibres, calcium silicate fibres, wood flour, coke, paper pulp, cotton waste, cotton jute, sisal, hemp, flax, rayon, or synthetic fibres such as polyester, polyamide and acrylonitrile fibres. The particulate material may also comprise ingredients which react together exothermically when ignited, e.g. aluminium, oxidizing agent therefor alone or together with a particulate refractory material. In the case of foamed products a non-foamed surface layer may be provided by defoaming the surface during manufacture or by providing the foamed material with a facing layer.

Title: Continuous uniform grafting process for keratin fibers
IPC: D06M14/00
Filed: 1968-05-21
Abstract: A continuous process for grafting a substrate comprising keratin fibres with an ethylenically unsaturated compound comprises the steps of passing the substrate through a zone in which the ethylenically unsaturated compound contacts the substrate, passing the substrate through an aqueous solution comprising a polymerization catalyst under such conditions that the unsaturated compound is grafted into the fibres, leading the substrate out of the aqueous solution and drying the substrate. Specified monomers, which may be in solution, include C 1 to C 12 -alkyl esters of acrylic esters, mixtures of such esters with each other or with styrene and styrene/dichlorostyrene mixtures. Suitable catalysts include redox systems. The catalyst solution may contain a swelling agent for the fibres and a wetting agent. The graft polymerization may be conducted in an apparatus comprising a zone containing the monomer and a vessel containing the catalyst solution, the substrate being passed successively through the zone and the vessel by means of moving endless belts. In the examples, wool top is grafted with n-butyl methacrylate or methyl methacrylate and a polyethylene terephthalatewool blend fabric is grafted with n-butyl methacrylate.

Title: Method of feeding yarn to a knitting place on a textile machine
IPC: B65H51/22
Filed: 1970-01-08
Abstract: In a yarn feed to a knitting machine, yarn F from a bobbin 2 is wound tangentially under tension on to a storage drum 7 on which it is displaced axially by an element lying at an angle on the drum periphery or sliding thereon and which forms an irregular ball from which the yarn is withdrawn axially. As shown bobbin 2 is carried on a pin 3 on a carrier arm 1 mounted on a knitting machine frame and is fed through yarn guiding elements 4, 5, 6 and a disc brake 8 to the driven storing drum 7 mounted beneath arm 1. Drum 7 is formed by a circular end carrying a series of rods 7a. The rim 9b of a spoked wheel 9 fits on the outside of the drum 7 with the wheel inclined to the longitudinal axis of the drum and biassed by spring F', the spokes 9a extending between rods 7a. When yarn builds up on drum 7, it finally causes wheel 9 to pivot against spring F' and operates a microswitch to stop the motor driving the drum. When sufficient yarn has been used, wheel 9 pivots down again and switches the motor on. In modifications, drum 7 may be stationary and the yarn wound on by a rotatable arm. Drum 7 may be a closed polished cylinder or may be polygonal. A sliding element may engage longitudinal grooves in the outside of the drum. A photoelectric device may be used to control the drum being operated by light reflected from the drum surface.
