Abstract: 1,125,477. Foamed sheets; flattened tubes; laminating. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 27 Oct., 1966 [29 Oct., 1965], No. 48254/66. Headings B5A and B5N. Foamed plastics sheets, e.g. of polystyrene are produced by passing an extruded foamed tube while its inner face is still in a hot-plasticized condition between flattening means whereby the tube is flattened and opposed sections thereof are fused together. Preferably, air pressure is maintained inside the tube so that the diameter of the completely foamed tube is further increased by 10-100%. The inner face may be additionally heated before flattening. Covering layers, e.g. of craft paper, may be passed between the flattening means and tube so as to bond the layers to the tube, preferably by heating the tube surface to melting-point, e.g. by using heated flattening means, or by heating before passing the tube through the flattening means. The tube may also be profiled simultaneously with or subsequently to the flattening thereof. The sheet produced may have a thickness of 5-200 mm.

Abstract: <PICT:1095168/C1/1> A mould for forming a reflector is formed by assembling rods 30 with shaped ends 31 in a bundle, the ends forming a facet of the mould, the other ends of the rods being joined by fusion welding. As shown, the mould forms the reflective face for a vehicle reflector made of plastic or glass, the rods 30 are hexagonal, and the ends 31 have cubic corners, and each rod being just under 2 inches in length.  Initially, the bundle is secured by a clamp 32 when the ends 31 are in their correct mutual positions.  A further clamp 36 is applied and the rods are severed at L.  The severed ends are then fusion-welded in an inert atmosphere, the clamp 36 and ends 31 being immersed in a liquid coolant.  The bundle is then heat-treated and the severed ends are ground to form an accurate surface.  The clamp 36 is then removed, and the bundle is then secured by welding or by bolts in either single or multiple arrangement to a block or base to form the mould part.
