Title: Magnesium cuprous chloride electric battery
IPC: H01M6/30
Filed: 1954-11-12
Abstract: 757,473. Batteries. MINISTER OF NATIONAL DEFENCE OF H.M. CANADIAN GOVERNMENT. Nov. 12, 1954 [Oct. 8, 1954], No. 32927/54. Class 53. A primary cell having a magnesium anode has a cathode consisting of a copper sheet 18 carrying on each face a layer of cuprous chloride 21. To secure good adhesion between the cuprous chloride and copper sheet, the latter is formed with raised portions 19 which may be produced by a punch or they may consist of the burrs formed by drilling holes in the sheet. The raised portions 19 may protrude through the layers of cuprous chloride as shown at 20. The cathode may be made by casting cuprous chloride round the copper sheet in a mould or by dipping the sheet in a bath of molten cuprous chloride. When a moulding process is used, potassium chloride may be mixed with the cuprous chloride to lower the melting point. The surface of the cuprous chloride may be reduced to metallic copper by sweeping it with a reducing gas flame or by covering it with tin foil and heating till the surface of the cuprous chloride melts. The cell is made up by placing a magnesium anode on each side of the cathode with intervening absorbent separating sheets and binding the whole with tape. Alternatively, the members of the cell may be held together by pins which connect the anodes together and pass through holes lined with rubber in the cathode. The electrolyte consists of water or sea-water.

An adhesive compaction comprises a polymer derived from a monomer mixture including (A) at least 74% by weight of acrylic ester, (B) a hydroxy ester of a polymerizable unsaturated carboxylic acid and (C) a polymerizable unsaturated carboxylic acid, the alcohol chain of the acrylic ester having a straight chain of a mean average length of from 5 to 9 carbon atoms attached to the carbon atom connected to the carboxyl group, each of said carbon atoms being bonded to at least one hydrogen atom. Specified esters (A) are 2-ethylhexyl acrylate and n-heptyl acrylate, and a methacrylate ester may also form part of the monomer mixture. Specified hydroxy esters are the monoacrylates and monomethacrylates of ethylene or propylene glycol. Preferred acids (C) are acrylic acid, methacrylic acid and monoesters of dicarboxylic acids, e.g. mono-n-butyl maleate. The copolymers may be prepared in aqueous emulsion by pre-emulsifying a major part of the monomer mixture and adding the pre-emulsified mixture gradually to the remaining reactants. In the examples, copolymers of (I) 2-ethylhexylacrylate, propylene glycol monoacrylate and methacrylic acid, (II) 2-ethylhexyl acrylate, propylene glycol monoacrylate, acrylic acid and vinyl acetate, (III) 2-ethylhexyl acrylate, propylene glycol monoacrylate, methacrylic acid and methyl acrylate and (IV) 2-ethylhexylacrylate, 2-hydroxypropyl acrylate, methacrylic acid and methyl acrylate are produced in aqueous emulsions. The emulsions produced have a particle size of less than ¢ micron and the pH of the emulsion produced in Example I is raised with ammonia.

Title: Improvements in or relating to explosive welding
IPC: B23K20/08
Filed: 1965-08-03
Abstract: 1,121,422. Welding by pressure. GENERAL PRECISION Inc. 3 Aug., 1965 [3 Aug., 1964], No. 33262/65. Heading B3R. In welding a first metal member to a second metal member by detonating an explosive charge against the second member which is spaced from the first member the space between the members is evacuated prior to detonation of the explosive and a sheet of material constituting a gas shield is sandwiched between and extends beyond the second member and the explosive to hinder gases generated by the explosive from entering the space between the members. A first member 11, Fig. la, rests on an anvil 12 and second member 13 is arranged at an angle thereto e.g. of 1 degree to more than 10 degrees. A gas shielding layer 14 is attached to the member 13 by a plastic or glue layer 15, a rubber layer 16 overties the layer 14 and the explosive sheet 17 of PETN lies on the rubber. One or more cavities in the member 13 are filled with low melting metal and a low melting metal is placed around the edges of the member to protect the edges. The assembly with the workpieces pre-cooled by immersion in liquid air or nitrogen is arranged in a chamber 24 which is evacuated prior to detonation of the explosive at the side close to the member 13. The low melting metal may be melted away. Instead of PETN, cyclotrimethylenetrinitramine, nitroguanadine or picric acid may be used. In a modification two further workpieces are arranged above the workpiece on the anvil and are supported in spaced position by end supports. A recoil block is also provided above the explosive layer. In another embodiment two workpieces are arranged in parallel relation and the explosive layer has a tapering cross section, the side with greater thickness being ignited. The upper workpiece or an attenuator may be tapered as an alternative. To produce a lined bearing a frusto conical liner 13c, Fig. 5, is positioned in a cylindrical bore 37 in a member 11c and a conical expolsive charge 17c is detonated at its end using a frusto conical gas shield 14c. In an alternative method the liner is cylindrical but of smaller diameter than the bore and the explosive is in cylindrical form. Semi-cylinders may be lined by the same methods. Alternatively a semi-cylindrical liner 13e, Fig. 7, is arranged in a semi-cylindrical surface 39 in a workpiece lie and the semicylindrical explosive is initiated on a side rather than an end thereof. A metal cladding may be welded to a hemispherical dome, the cladding being initially spaced from the dome and covered with an explosive layer which is initiated at the centre thereof. The workpiece on which the explosive is positioned may be of steel or aluminium.

Class 75(1) A compressor forming an oil mist for delivery to a burner (not shown) is immersed in an oil heating chamber 15. The oil is heated by an electric immersion heater 7 controlled by a thermostat 8. The oil passes from a tank to a filter chamber 15a and then to an adjustable displacement pump (not shown) which delivers the oil to an inlet 14a in the heating chamber 15. The heated oil passes through a valve 17 to a duct 21 which is also connected to an air inlet having a filter 20 and which leads to the compressor 5. The valve 17 has a bellows connected by a duct to the delivery side of the compressor and cuts off the oil flow when the delivery pressure of the oil mist is below a preset value. Should the valve 17 close a spring loaded relief valve 25 opens to allow oil to circulate through the filter chamber, the displacement pump and the heating chamber.

Abstract: 1,124,736. Printing machines. MIEHLEGOSS-DEXTER Inc. 29 July, 1966 [13 Aug., 1965], No. 34114/66. Heading B6C. In a rotary printing press wherein the end edges of printing plates mounted on the plate cylinder 10 are spaced so as to leave a gutter, the surface of the impression cylinder is shaped so that a gradual decrease and increase of pressure between the cylinders occurs in the vicinity of the gutter thus obviating streaks in the printing caused by sudden variations in pressure when the gutter reaches the printing position. In one embodiment, the impression cylinder 30 is cut away at the shaded area 57 Fig. 2a, which includes the part normally engaging the gutter. The area extends beyond the gutter so as to gradually reduce the pressure between the cylinders gradually as the gutter approaches the printing position and to increase the pressure gradually as the gutter leaves the printing position but maintains a printing pressure between the plates and the impression cylinder up to the edges of the plates. In a modification, a metal underlay is provided between the impression cylinder blanket and the cylinder and is cut away as described above in the area where it would be opposite to the gap. The ends of the plates may be secured by devices mounted in the gutter, or the gutter may be a groove in the plate situated between parts of the plate printing separate pages.
