Title: Vulcanisable rubber compositions
IPC: C08L21/00
Filed: 1957-03-14
Abstract: A natural or synthetic rubber composition contains a minor amount by weight of polythene of specific gravity more than 0.92. The rubber and polythene may be blended at a temperature equal to or greater than the melting point of the polythene. Preferably, the weight of the polythene is between 10 and 35% of the combined weight of rubber and polythene. The synthetic rubber may consist of a butadiene-styrene or isoprene-butadiene copolymer. When the composition is vulcanized it has high tensile strength, modulus, and elongation at break, resistance to ozone attack, and electrical resistivity. It is thus useful in the manufacture of electric cables, tyres, and microcellular soles for footwear. In one example, a microcellular material is prepared by vulcanizing in a press a composition containing (in parts by weight) isoprene-butadiene copolymer 100 and polythene 30, or butadiene/styrene copolymer 100 and polythene (of specific gravity 0.94) 10, or pale crepe 100 and polythene 15, calcium silicate 60, china clay 30, purified wood cellulose 15, petroleum jelly 10, and small amounts of zinc oxide, titanium dioxide, sulphur, accelerators, antioxidant, and, as blowing agent, N,N1-dinitrosopentamethylene, with or without p-dinitrosobenzene.

Title: Manufacture of flat glass utilizing a reaction to traction across the width of the molten glass
IPC: C03B18/06
Filed: 1972-09-16
Abstract: Molten glass is poured on to a bath of molten metal to form a pool of molten glass on the bath, which pool is held back on the bath surface by an elongate member which can be solid, wetted by the glass, extending across the downstream end of the pool. A ribbon of glass is drawn from a forward flow of molten glass beneath the member and the ribbon is rapidly cooled to stabilize its dimensions as it is drawn away from the member. The glass is heated in the region of the member to maintain forwardly flowing glass in that region at a viscosity which is lower than the viscosity of molten glass of the pool upstream of the member but at viscosity at which the glass also wets on to the member. The ribbon is drawn from the lower viscosity, forwardly flowing glass.

Abstract: The invention relates to inflatable tubes such as buoyancy tubes for inflatable liferafts and is aimed to provide tubes with bends in them that can be formed with a considerable reduction in the number of cutting and joining operations conventionally required and with a corresponding reduction in numbers of seams and hence sources of leakage. The invention provides a method of making such tube by overlapping and joining the longitudinal edges (231) of a suitable sheet material (230) to make a flattened tube (230A), marking on said tube a fold line (234) corresponding to the desired bend position, marking corresponding areas (237A, 237B) one on each side of the fold line, folding about the fold line to bring and join together these areas and then sealing the ends (232A, 232B) of the tube. By making a number of bends the ends of the tube can be sealed to each other, thereby making an endless tube of polygonal plan form.
