Title: Improvements relating to internal-combustion engines having pneumatic starting systems
IPC: F02B71/02
Filed: 1945-03-09
Abstract: 594,013. Preventing starting when an engine member is removed. PESCARA, R. P. March 9, 1945, No. 5975. Convention date, June 30, 1943. [Class 7 (v)] In an engine which is started by admitting a charge of compressed gas to a chamber other than the combustion space, damage to the engine due to the starter being operated when a member of the engine such as a fuel injector has been removed is prevented by arranging that the removal of the member necessitates opening to atmosphere the duct which conveys starting gas to the engine. The Figure shows a free piston engine which is started by compressed air from a reservoir 5. The fuel injector 17 is so arranged that before it can be removed a connection 15 associated with the compressed air supply linefrom the reservoir has to be broken. When the connection is broken if the starting control is operated in error, the compressed air supply will escape and starting be prevented. The starting arrangement includes a chamber 5 and valve 7 controlled by a piston 11. The piston 11 carries a non-return valve 10. The compressed air from the supply pipe 12 enters the chamber 5 through the non-return valve. When a cock 9 in the supply pipe is turned to connect the pipe to the atmosphere the pressure in the chamber 5 operating on the piston 11 opens the valve 7 and the compressed air flows to the cylinder 4 of a compressor of the engine and operates the engine for starting. The Specification as open to inspection under Sect. 91 states that removal of the fuel injector can be arranged to interrupt the circuit of an electric starting motor. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of condensers having plastic film dielectrics
IPC: H01B3/00
Filed: 1946-07-26
Abstract: The borders of polymerised &c. plastic film dielectrics for condensers are masked while metallising by a wet chemical process, by coating them with a paste which is subsequently dissolved away with a solvent which does not affect the film or its metal coating.  The masking coating may be a solution of cellulose acetate in acetone, or oil or grease dissolved in ethyl alcohol, the same solvents being used to remove the coating, assisted by friction or shaking.  A polystyrene film, plain or loaded with a filler such as titanium oxide, may be used and this may be silvered by immersing in a solution of silver salts to which a reducing solution is added.  The thickness of the metal coating may be subsequently increased by electrodeposition.  A film coated on one side only may be obtained by passing it over an absorbent roller carrying a demetallising solution.
Patent GB-669907-A (GB)
Title: Improvements in or relating to the manufacture of moisture-proof sheet wrapping materials
Inventor: BERRY WILLIAM
IPC: B29C48/08
Filed: 1949-03-08
Abstract: An aqueous emulsion of vinylidene chloride polymer or copolymer is applied to a base sheet of hydrophilic, water-insoluble, non-fibrous organic material in a layer of such thinness that the water of the emulsion is substantially wholly absorbed by the base sheet and the dispersed polymer or copolymer deposited on the sheet in the form of a layer, and the layer is stripped from the base sheet to form a sheet of moisture-proof wrapping material. The deposited layer is preferably dried and consolidated by heat either before or after stripping.  The base sheet may be in the form of a sheet, a continuous length or an endless band, thus making the process discontinuous or continuous.  Preferably, it has a smooth surface and shows a variation of diffusion coefficient (as defined in the Specification) with water content to ensure a short time lag before extraction of the water of the emulsion begins.  The preferred basesheet is a film of regenerated cellulose, but other materials such as lowly substituted cellulose esters and ethers, alginic and albuminous materials and wholly or superficially saponified cellulose acetate may be utilized.  The regenerated cellulose base sheet should preferably have a water content (based on the dry sheet) of between 4 per cent and 8 per cent.  The relative thicknesses of the regenerated cellulose basesheet and of the emulsion layer should be such that when absorption is complete the water content of the regenerated cellulose sheet should be between 15 and 30 per cent (based on the oven dry weight), thus facilitating stripping. The base sheet may be a thick film as cast or a laminated sheet. The preferred copolymers for the emulsion contain between 80 and 98 per cent monomeric vinylidene chloride, the remaining ingredient or ingredients being vinyl chloride, styrene, acrylonitrile or an alkyl acrylate or alkacrylate in which both the alkyl group of the ester group and that of the acid group comprise not more than 4 carbon atoms.  The stripped, dried film may be cold stretched if desired.  In an example (all parts by weight) an aqueous emulsion is prepared from 9 parts of vinylidene chloride, 1 part of acrylonitrile, 1 part of a 20 per cent aqueous solution of the sodium salt of C12-C18 alkyl sulphates, 0.06 part of ammonium persulphate, 0.03 part of sodium metabisulphite and 12.5 parts of water.  In the cold emulsion (after polymerization at 39 DEG  C.) a laminated sheet of regenerated cellulose (0.006 inch thick and 4 per cent water content) is immersed for 1 second, withdrawn and allowed to drain for 15 seconds.  The deposited layer is stripped off and dried and consolidated by radiant heat to give a clear moisture-proof film 0.0008 inch thick.  Specifications 654,342 and 655,732 are referred to.

Abstract: 577,310. Supplying liquid fuel. PUGH, C. A., BOOTH, D. G., and PLESSEY CO., Ltd. May 19, 1941, No. 6431. [Class 7 (iii)] Fuel-supply apparatus for internal-combustion engines or other fuel-consuming means used more especially in aircraft comprises a main fuel pump having its inlet connected to a fuel tank and its outlet serving to deliver fuel under pressure to an engine, a second pump having its inlet connected to the fuel tank, means controlling the delivery of this second pump to boost the pressure at the inlet of the main pump or at the inlets of both pumps, and for alternatively directing the flow of both pumps to the engine. In the arrangement shown in the Figure, the control valve 51 is shown in the normal position. In this position the secondary positive displacement pump 41 draws fuel from the tank 42 and forces it through the valve 51 to the inlet 49 to the main pump 40. This pump, which is fitted with a relief valve controlled by-pass, delivers fuel to the engine by way of pipes 53, 56 under the control of a throttle valve 55 and a speed-responsive control mechanism 200. When starting the engine the valve 51 is operated to put the pumps in parallel. In this position excessive pressure in the secondary pump outlet is relieved through a spring-loaded by-pass valve 61 while in the former position it is relieved through a spring-loaded by-pass valve 46 which also provides a seat for a spring-loaded non-return valve (not shown) through which the main pump is supplied when the pumps are in parallel. In a modification the secondary pump, in the normal running position, forces fuel through an injector boosting device housed in the fuel tank. Specification 577,311, [Group XXIX], is referred to.
