Title: Improvements in the manufacture of artificial threads or fibres
IPC: D01F2/06
Filed: 1938-03-01
Abstract: 512,471. Artificial threads. GROVES, W. W. (I.G. Farbenindustrie Akt.-Ges.). March 1, 1938, No. 6411. [Class 2 (ii)] Viscose is spun into a bath having only a coagulating effect so as to form cellulose xanthate threads and these threads are first subjected to a strong stretching in a bath which neither dissolves nor decomposes them and is maintained at a raised temperature, and are then decomposed chemically or thermally to cellulose hydrate in a further bath. The stretched threads may be cut into staple fibres before they are decomposed to cellulose hydrate. In an example, viscose is spun into a bath comprising ammonium sulphate and sodium sulphate, guided over glass rods, and stretched in a bath containing sodium sulphate at 50‹C. The threads are then cut and decomposed in a boiling solution of sodium sulphate. In a second example, viscose is coagulated in a bath containing ammonium sulphate and\ sodium sulphate, tensioned, and stretched in a solution of sodium sulphate at 50‹C. After stapling, the threads are decomposed in a bath containing sulphuric acid and sodium sulphate. In a further example, xanthate threads spun as above are stretched in a sulphate bath at 80‹C., and then decomposed in a boiling solution of sulphuric acid.

Filed: 1941-05-23
Abstract: 550,170. Cellulose derivative compositions and articles. BRITISH CELANESE, Ltd. May 23, 1941, No. 6612. Convention date, May 24, 1940. [Class 2 (ii)] Moulded articles, such as sheets, tubes, discs, buttons, or knobs, are obtained by mixing fibres of a thermoplastic derivative of cellulose with a thermoplastic composition having as a base a thermoplastic organic derivative of cellulose compatible with the cellulose derivative of the fibres, and moulding the mixture so that the thread-like nature of the fibres is not destroyed. The fibres, before incorporation in the plastic mass, may be dyed in any desired colour. For obtaining ornamental effects, they may be coloured so as to contrast with the base material. The composition may be extruded or injection moulded. Pigments, dyes, lakes, fish-scale, powdered metals, talc, mica, barytes, cork, or woodflour, may also be incorporated in the plastic composition. Preferably the fibres are used in short lengths, e.g. ¢ to 2 inches. The fibres may be plasticized or not, and they may be partially saponified or weighted. The cellulose derivative may be cellulose acetate, propionate, butyrate, or aceto-propionate, or methyl or benzyl cellulose ether. Specified plasticizers for incorporation in the fibres or the plastic base are dimethyl-, diethyl-, or di- (methoxy ethyl)- phthalate, triphenyl phosphate dibutyl tartrate, or methyl xylene- or ethyl toluene-sulphonami de. In an example, a composition comprising plasticized cellulose acetate and plasticized coloured cellulose acetate fibres in short lengths is fed into a moulding press at 120‹ C. under a pressure of 1,500 Ibs./ sq. inch and formed'into fancy discs. In another example, plasticized cellulose acetate fibres, weighted by treatment with stannic chloride, are mixed with plasticized cellulose acetate. The mass is moulded into the form of buttons.

Title: Improvements in or relating to electrolyte reservoirs for deferred action electric batteries
IPC: H01M6/38
Filed: 1962-02-21
Abstract: 995,860. Forcing liquids by gaseous pressure. TARDNEY INTERNATIONAL CORPORATION. Feb. 21, 1962 [Feb. 27, 1961], No. 6765/62. Heading F1R. [Also in Division H1] A reservoir 3 for a deferred action battery has a normally sealed electrolyte outlet passage 55, a normally sealed inlet passage 41 connected to a gas generator e.g. a powdered fuel ignited electrically, a coiled partly perforated tube 23 within the reservoir containing a substantial proportion of the electrolyte and being connected to one of the passages so that on activation of the gas generator the seals are broken by the rise in fluid pressure and the gas must flow through the tube 23 and eject electrolyte before reaching the outlet passage 55. With the tube 23 connected to the inlet passage 41 gas from the generator ejects electrolyte through the perforations into the reservoir. The force of the ejected electrolyte ruptures a diaphragm 19 in the outlet passage 55 and substantially all the electrolyte originally in the tube flows into the cells of the battery. When the tube is empty the gas escapes through the perforations to the top of the reservoir and ejects about half of the remaining electrolyte into the cells. With the tube 23 connected to the outlet 55 gas is introduced to the top of the reservoir and expels first the electrolyte contained in the tube and then part of the electrolyte remaining in the reservoir. Reference has been directed by the comptroller to Specification 913,394.

Filed: 1946-03-05
Abstract: 609,056. Operating clutches. CARDIFF FOUNDRY & ENGINEERING CO., Ltd., and GLASTONBURY, J. R. March 5, 1946, No. 6766. [Class 80 (ii)] In a mechanism for actuation of a onerevolution clutch to obviate accidental repetition of a working stroke of a power-driven machine, a stop 8 bears against a lever 6 secured to a segmental key 5 in the disengaged position of the clutch shown in the Figure. Depression of a trigger 110 by actuation of a lever 14 causes the stop 8 to be moved clear of the lever 6 which under the action of a spring 7 rotates so that it abuts against the stop 30, the segmental key thus engaging a keyway in the driving member. During the rotation of member 3, finger 13 strikes trigger head 11 moving it clear of the stop 8 which returns to its original position under the action of a spring 17. During subsequent rotation of the member 3, trigger head 11 rides over the cam surface 12 and is thus prevented from reengaging stop 8. On completion of the revolution, the lever 6 is struck by stop 8 causing disengagement of the clutch.

Abstract: 104,270. Ganthony, R. May 13, 1916. Cylinders, construction of; reservoirpressure, regulating. - A combustion chamber 22 of adjustable capacity, but large enough to hold a charge that would more than fill the cylinder of a two-stroke-cycle engine at atmospheric pressure, is separated from the cylinder by a valve 19 and is scavenged by air or by a spring piston 12 before the combustible charge is admitted. The movement of the piston is limited by a screw stop 13. The ignited charge may be admitted to the power cylinder 1 after the beginning of the power stroke; in this case, the exhaust valve 8 is closed before the end of the in-stroke. to equalize the pressure between the cylinder and combustion chamber when the valve 19 opens. The charge is supplied from a reservoir, and its pressure is controlled by a by-pass valve on the pump delivery pipe, or by holding open the inlet valve of the pump by a sliding cam. The engine is started by admitting tn a cylinder making a working stroke, a charge from the pump, the admission valve 9 being opened by hand for this purpose, and the clearance 22 reduced to its minimum.
