Title: Improvements in Laminated Articles and methods for producing the same
IPC: B32B15/08
Filed: 1967-01-16
Abstract: 1,161,944. Laminates. GENERAL ELECTRIC CO. 16 Jan., 1967 [17 Jan., 1966], No. 2294/67. Heading B5N. [Also in Division B2] A process for adhering a polymer of ethylene to a solid substrate comprises (1) incorporating in the polymer of ethylene an organic peroxide in an amount equal to from 0À1 to 15% by weight based on the weight of the ethylene polymer, (2) applying the polymer of ethylene directly to a solid substrate of metal, ceramic, plywood, fibreboard, cardboard or paper, and (3) pressing the polymer of ethylene directly into place on the substrate by means of elevated temperature and pressure for a time sufficient to effect curing of the polymer of ethylene and adhesion to the substrate. As described the ethylene polymer is applied in powder form, e.g. by spraying, and the organic peroxide is incorporated therein by suspending the ethylene polymer in a liquid which contains the peroxide and which is a solvent for the peroxide but a non-solvent for the ethylene polymer, allowing the ethylene polymer to absorb the peroxide from the solution, removing the liquid by filtration, and removing the residue of solvent by heating. The organic peroxide is preferably of the formula where R 1  and R 6  are aryl radicals and R 2 , R 3 , R 4  and R 5  are of the class consisting of hydrogen and alkyl radicals of less than four carbon atoms, or it may be tertiary butyl perbenzoate, tertiary butyl hydroperoxide, or an acetylene or alkyl peroxide. The ethylene polymer may also include a filler, e.g: treated clay, metal powder, ground ceramic, TiO 2 , fume silica, carbon black, or calcium carbonate, and/or pigments. The ethylene polymer may be a copolymer of ethylene with propylene, butylene, methyl methacrylate or vinyl acetate, or a terpolymer of ethylene, propylene and isobutylene. In examples polyethylene is adhered to a substrate of aluminium to form a decorative panel; or is adhered between two substrates of aluminium, copper, or steel; or is adhered to each face of a substrate of metal, or, in the case of containers, paper. In other examples multiply laminates comprise a number of layers of polyethylene and steel, copper, or aluminium; or of copper and ethylene/propylene copolymer; or of aluminium and ethylene/isobutylene copolymer. The laminates formed are abrasion resistant, and may be used as electronic components, tanks for liquids, vehicle parts, steam hose, diaphragms, mounts, and rolls.

Abstract: 178,217. British Thomson - Houston Co., Ltd., (General Electric Co.). Jan. 18, 1921. Transformers.-The body portion 17 of a casing or tank for transformers and other electric apparatus consists of corrugated walls formed by bending sheet metal along parallel lines, the parts of the casing formed by the corrugations being closed by separate inserted end pieces 26. The walls are made up of units, each of which preferably comprises two or more corrugations united by plane back portions 20. The side portions 22 of the units are formed with upturned edges 23, and similar edges 27, 28 are formed on the end pieces 26, so that the parts may be readily secured together preferably by welding. The crests of the corrugations are notched at 30, and the edges of the end pieces are cut away at the tips, in order to permit the end pieces to shed water when the tank is used in an outdoor installation. The tank is secured to a base 10 by means of rods 32 provided with lifting-eyes 33. Specification 119,450 is referred to.

Abstract: 987,883. Moulding hollow articles. MARRICK MANUFACTURING CO. Ltd. Jan. 25, 1963 [Jan. 26, 1962], No. 3068/62. Addition to 926,589. Heading B5A. [Also in Division H5] Discrete lengths of thermoplastic tubing are heated in an oven and then expanded into hollow articles by blow-moulding. The apparatus comprises an oven, Fig. 1, a pre-treating station 26, a moulding station 23, an unloading station 24 and a loading station 25. The loading station comprises a hopper from which lengths of tubing are successively fed into a recessed tray from which they are transferred on to mandrels 22 by a transfer mechanism comprising a rotatable drum having a plurality of transversely disposed sleeves. The oven, Fig. 3, is generally rectangular and has glass fibre insulation 25 and heating elements 42. The mandrels are moved through the oven by a conveyer comprising slats supported by chains 46 which run on sprockets 47 mounted on a shaft 48 which is indexed by an hydraulically actuated ratchet device. The mandrels are rotated by roller chains 62 as they advance through the oven so as to provide uniform heating of the tubing lengths 44. Additional heating elements 63 are provided to compensate for loss of heat to the mandrel spigot. At the discharge end of the oven an hydraulic ram 72, 73 operates an ejection mechanism which pushes the foremost row of mandrels on to the track 21 formed by a pair of spaced rails which is indexed by an hydraulically actuated reciprocating dog 86. The mandrels are accurately located on the track 21 by hydraulically actuated locating means 28, 29 and the end of the track 21 is accurately aligned with the adjacent pair of slats in the oven by an hydraulically operated aligning mechanism. The pre-treating station 26 is provided with a fan 97, heating elements and baffles arranged to direct hot air on to special areas of the tubing lengths and with nozzles which direct jets of cool air on to other areas of the tubing lengths. The moulding station comprises multi-cavity dies 99, Fig. 8, carried by water cooled platens 98 controlled by hydraulic rams 100. As the platens close spring-loaded grippers 101 nip the top of the tubing lengths and nozzles 102 are moved into the spigots 57 of the mandrels. Compressed air is then supplied to the nozzles 102 to effect blow moulding. At the unloading station 24 an hydraulic ram operates to cause a spring-loaded tube 140, Fig. 14, to move so that jaws 148 cut into the flash on the adjacent articles. On continued operation of the ram the table is raised to lift the moulded articles from the mandrels and a cam effects forward movement of a stripper bar 151 which dislodges the moulded articles from the jaws 148 whereupon a plate 159 topples the articles into a receptacle. A timing device determines the duration of mould closure and the limits of all the motions are sensed by limit switches and signalled to the control equipment.
