Title: Improvements in and relating to composite metallic articles
IPC: B22F7/04
Filed: 1937-06-11
Abstract: 496,763. Composite metallic articles. GENERAL MOTORS CORPORATION. June 11, 1937, Nos. 16236 and 16237. Convention dates, June 15, 1936 and Aug. 7, 1936. [Class 82 (ii)] A composite metallic article, e.g. a bearing member, is made by applying a layer of powdered metallic material to a metal base, heating to such a temperature that the powder is sintered to form a porous layer bonded to the base, and then impregnating the porous layer with a void-filling material. The base may be a ferrous metal strip which is preferably copper plated and the metallic powder which forms the porous layer may be, for example, copper, iron, nickel, copper-nickel alloy, copperiron alloy, mixtures of copper and nickel, mixtures of copper and tin with or without graphite and /or magnesium carbonate, or mixtures of copper, tin, and lead. The voidfilling material may be molten lead, litharge, mixtures of lead and litharge, or metals such as tin, antimony, bismuth, silver, cadmium, tellurium, and calcium, either alone, alloyed with one another, or alloyed with lead. Besides lead and litharge the following voidfilling materials are particularly useful: (a) pure tin, (b) lead-tin alloys, (c) lead-antimony alloys having 1-10 per cent of antimony, (d) lead-tin-antimony alloys with 1-10 per cent of antimony, (e) tin-antimony alloys with 1-8 per cent of antimony, and (f) tin-copper alloys with up to 10 per cent of copper. The porous layer may be formed as shown in the Figure, the powder being fed from a hopper 12 on to the base 11 and smoothed by the member 14. The coated base is then passed through the sintering chamber 20 and the cooling chamber 22, the chambers being filled with dried reducing gas passed into the chamber 20 at 23. The cooled porous layer may be subsequently compacted, e.g. by pressure rollers 30, 31. The void-filling material may be similarly applied, the sintering chamber being replaced by a chamber which is heated to a temperature above the melting point of the void-filling material. Instead of applying this material in powdered or granular form, it may be laid on the porous layer in the form of foil or sheets. Alternatively, when the molten impregnating material tends to dissolve the porous layer, as in the case when lead alloys, tin, &c. are used to impregnate a copper layer, the layer is impregnated with a flux solution, e.g. an aqueous solution of zinc chloride, ammonium chloride, and hydrochloric acid, or a solution of zinc chloride and /or ammonium chloride in a high boiling point alcohol, and then immersed in a bath of the impregnating material maintained at a temperature only just above its melting point, withdrawn, and rapidly cooled. As a further protection against attack some of the metal constituting the porous layer may be added to the impregnating material. The composite material may be used for making anti-friction bearings or high friction elements such as clutch discs or brake shoes.

Patent GB-1092103-A (GB)
Title: Polymeric materials
Inventor: GAZZARD EDWARD GEORGE
IPC: C08F24/00
Filed: 1964-04-20
Abstract: Polymeric addition products are obtained by reaction of at least one pyran aldehyde of the general formula <FORM:1092103/C3/1> wherein R and R1 represent hydrogen, a hydrocarbon radical or halogen with at least one compound containing an activated methylene group (defined) and polymerization through the double bond.  The formation of the addition product and the polymerization may be carried out as a single step or alternatively the addition product may be formed first and subsequently polymerized.  Suitable polymerization catalysts are those known for vinyl ethers and include both acidic and non-acidic catalysts.  Suitable catalysts for the formation of the addition product are acids or bases.  Foamed cellular products are obtained by carrying out the polymerization in presence of a foaming agent, e.g. a halogenated hydrocarbon.  Surfactants, e.g. polysiloxane polyoxy alkylene block copolymers may also be incorporated.  Examples relate to (1) a two-stage process comprising reacting acrolein dimer with cyclohexanone and subsequently polymerizing in the presence of a foaming agent and (2) a one-step process using the above ingredients.

Abstract: 957,582. Making composite rod. REYNOLDS METALS CO. April 30, 1962, No. 16451/62. Heading B3A. A method of making a composite metal rod comprises assembling a pair of metal channel members about a metal core so that the former engage a part of the outer surface of said core leaving uncovered gaps thereof between separated opposed edges of said channel members, hot rolling the assembly to bond the central portions of the channel members to the core and compress the rod assembly until said opposed edges of the members are in mutual pressing engagement thereby eliminating the gaps and covering the entire peripheral surface of said core with said members and hot rolling the assembly further to bond the edge portions of the members to the core and reduce the crosssectional area of the whole. Two corrosion resistant aluminium alloy U-shaped channel members 12, 14 are snap fitted over a high strength aluminium extruded core 10 of a square section so that the channels grip the core and gaps 30, 32 are provided between the ends of the channel legs 18, 24; 20, 26. The assembly is hot rolled about faces 16, 22 to compress the rod and the ends of the legs together, rotated through 90 degrees and hot rolled along the faces 18, 24, 20, 26 to bond the channels to the core. The composite rod 28 is then rolled to a substantially circular crosssection and drawn to reduce its diameter to produce screen wire 37 suitable for weaving into wire screens. In an example a 11/16 inch square section core and channels having a web thickness of <SP>5</SP>/ 32  inch were used. The rolling temperature was 800 ‹ F. initial passes reduced the assembly to 1¢ inches square and approximately 12 passes through grooved rolls reduced the section to # inch diameter, subsequently 27 passes through 'wire drawing dies, with suitable annealing, reduced the wire diameter to 0.013 inch. The method may be used to produce zinc clad, copper clad, silver clad, solder clad aluminium wires and copper clad steel and gold clad silver wire.
