Title: Improvements in nuts
IPC: F16B37/12
Filed: 1946-01-29
Abstract: 609,234. Locking nuts. FORGAARD, H. L. Jan. 29, 1946, No. 2836. [Class 89 (i)] A nut comprises a number of dished elements 10 inserted in a body 11 against a shoulder 12. After assembly the elements are preliminarily flattened to cause locking engagement against rotation with serrations 13 formed in the body. The elements are then drilled and tapped and on screwing up they flatten further, giving a self-locking action. The nut may 'have one or more untapped elements drilled to suit the crest diameter of the bolt, the elements being located adjacent to the bearing face of the nut and backed up by a threaded sleeve. Lead elements may be used when a sealing effect is required. A number of serrated recesses may be provided in a bar to receive sets of elements to form a strip nut. The bore 17 of the shoulder 12 may be chambered out at 29 and a plate 26 may be flanged into it at 27 to provide an anchor nut. The plate and nut may be connected with float. In a further form, the body has an external flange secured with float in an anchoring member.

Filed: 1973-01-19
Abstract: 1412329 Cleaning air filter LUWA AG 19 Jan 1973 [20 Jan 1972] 2939/73 Heading B1T In a method and apparatus for cleaning an air filter 18 which divides the filter housing into a dirty air chamber 14 and a clean air chamber 20, a shock wave of clean air is directed in reverse flow against the filter to clean impurities therefrom. In filtering air enters at 12 passes through filter 18 and propelled by fan 22 exits at 28. During the cleaning cycle simultaneous alteration of flaps or valves to the positions shown in Fig 2 takes place, i.e. flaps 46 and 48 cover the inlet, flap 34 covers the outlet, flap 38 restricts circulation and optionally flap 54 may open to allow extra air flow for transport of removed matter to exhaust pipe 16. The actuation may be operated by a solenoid depending on time or pressure differential. An alternative apparatus using two filter screens is illustrated in Figures 3 and 4 (not shown).

Abstract: 524,399. Nuts ; bolting. PEACE, Ltd., A., PEACE, A., and FIELD, C. L. Jan. 30 1939, No. 3062. [Class 89 (i)] A nut of the kind consisting of a number of parts divided in an axial plane so as to be readily detachable from the bolt, has one end of the thread chamfered and abutting against a truncated conical washer so as to exert a shearing strain on the means for securing the parts together, so as to facilitate opening of the nut when the securing means are withdrawn. The nut may be formed of two parts 3, 4, the abutting edges of the threads thereon being preferably chamfered off. One part 3 is formed at each end with a gap to receive a lug 5 on the part 4. A split pin 7 with opened ends serves as a pivot and a split pin 8 with a cord or chain connected to the eye 9 serves for securing the parts together. Alternatively two removable pins may be used or pin 8 may be replaced by a hinged member which embraces the parts. The underside of the nut is chamfered at 10 and a truncated conical washer inserted so that a shearing strain is exerted on the pins 7, 8 when screwing down the nut so that when the pin 8 is withdrawn the parts fly open. The nut may be a fly nut for use with ammunition boxes.

Abstract: 575,675. Waterproofing. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 25, 1943, No. 3138. Convention date, March 4, 1942. Divided out of 572,919, [Group IV]. [Class 140] Materials are waterproofed by treatment with a solution containing an organo-silicon halide, or a mixture of organo-silicon halides. Alternatively the material may be brought into contact with a liquid organo-silicon halide or a solution thereof in an inert non-reacive diluent, e.g., a liquid hydrocarbon, ether or chlorinated hydrocarbon. The acidity remaining in the treated material may be removed or neutralized by washing with water or a solution of an alkali, e.g., sodium or potassium hydroxide. In example 1, a clean glass surface is brought into contact with a mixture of methyl silicon chlorides consisting mainly of (CH3)SiC13, and (CH3)2SiC12 and is then not wetted by water. Graduated glass tubes, glass fibres or filaments, glass insulators, glazed porcelain insulators, oxidized aluminium foil, and aluminium ice cube trays and dividers may be so treated. Other examples refer to the treatment of porous absorbent paper with an ethereal solution of ethylsilicon trichloride or diethylsilicon dichloride or of both, to the treatment of filter paper with liquid mixtures of phenylsilicon chlorides, to the treatment of a clean glass surface with an ethereal solution of a mixture of methylsilicon bromides and chlorides, and to the treatment of filter paper with a dilute ethereal solution of (a) a mixture of organosilicon compounds boiling above 78‹C. at 12 m.m. pressure and containing C13,SiCH2CH2SiC13, (b) a mixture of C13SiCH2SiHC12 and containing C13SiCH2SiC13, or (c) a mixture of polymeric organo-silicon halides of the type -CH2SiCL2 boiling within the range of 120-137‹C. at 10 m.m. pressure and containing the trimer (CH2SiC12)3. Organo-silicon halides referred to in general are alkylsilicon halides (e.b., ethyl, propyl, and butyl silicon halides), arylsilicon halides (e.g., phenylsilicon halides, aralkylsilicon halides (e.g., phenylmehylsilicon halides, alkarylsilicon halides (e.g., tolylsilicon halides), and compounds such as (CH3)2HSiC1 and similar alkyl and aryl halosilanes. Other neutralizing agents for residual acidity are methylamine, ethylamine, diethyiamine, propylamine, dipropylamine; alkalimetal hydroxides and carbonates, e.g., sodium and potassium hydroxides and carbonates, and calcium hydroxide. Suitable solvents are methyl, ethyl, and propyl ethers, benzene, toluene, gasoline, and chlorinated solvents, e.g., carbon tetrachloride, ethylene chloride, and triethylene chloride. Reaction may occur between the compounds and cellulose, asbestos, and hydrated aluminium oxide. Specifications 572,740, 575,667 and 575,668, [both in Group IV], are referred to.

Abstract: 812,342. Granulating metals. BERK & CO. Ltd. Oct. 16, 1956 [Feb. 3, 1956], No. 3491/56. Class 82(2) Metal powders, for example powders of iron, nickel or copper alloys, are made by subjecting a falling stream of the molten metal to the action of an annular jet of water in an atmosphere of a non-oxidizing gas such as nitrogen, hydrogen, argon or cracked ammonia while keeping the jet stable by satisfying its tendency to draw in gas by supplying it with the non-oxidizing gas either from an external source or by a re-circulating pipe. As shown molten metal falls from a hole 4 in the base of tundish 3 when it is acted upon by a conical jet of water from the annular outlet 8 of water nozzle 7. The water level in the bottom of chamber 10 is controlled by overflow valve 15a, and the non- oxidizing gas is supplied at 11 and may be re-circulated to the nozzle 7 by pipe 19 with or without the aid of a pump 20, or the external supply 21 may be used. A manometer 18 indicates the pressure drop across the nozzle (usually 6-9 inches water gauge), and gauge 13 indicates the pressure in the chamber (usually 10-30 inches water gauge above atmospheric). A recirculation rate of 60-80 cubic ft./min. is stated to be satisfactory for a pouring hole of 3/32 in. diameter. Specifications 719,047 and 812,341 are referred to.

A thermoplastic synthetic resin is moulded by placing it under vacuum in a molten state in a heated mould for a sufficient period to remove occluded vapours therefrom, and the molten resin is then compressed whilst cooling it to solidify successive portions thereof, so that the formation of internal voids caused by the shrinkage of the resin during cooling is prevented. The synthetic resin may be a polymer or copolymer of ethylene, propylene, butylene, or other mono-olefin, or of a diolefin such as butadiene or isoprene, or may be a polyalkyl acrylate, a styrene polymer, or coploymer such as butadiene-acrylonitrile-styrene terpolymer or acrylonitrile-styrene copolymer, or may be cellulose acetate. The resin may be introduced into the mould as a liquid or as solid particles. A rod may be moulded in a cylindrical mould 2 provided with electrical heating coils 2, a piston 14 for compressing the resin, and an outlet 8 for removing the occluded vapours.
