Title: Improvements in or relating to ornamental compound sheet materials
IPC: B32B27/00
Filed: 1935-03-30
Abstract: 454,442. Compound sheet materials. BRITISH CELANESE. Ltd., and MILLER, B. E. M., 22, Hanover Square, London. March 30, 1935, No. 10019. [Class 140] An ornamental compound sheet material comprises a transparent or translucent sheet material backed with a pile fabric and in which the pile shows through in a pattern. The pattern may be derived from colour, from differences in lustre, e.g. due to the presence of yarns of different character or differences in the lay of the yarns as in a crushed pile fabric, or from differences in thickness of the pile as in a locally carbonized pile fabric. Haphazard pattern effects may also be obtained by pressing the sheet material on to the pile of the fabric in such a manner that the pile is deformed non-uniformly. The sheet materials may have a basis of regenerated cellulose or nitrocellulose or a non-cellulosic transparent substance. Organic derivatives of cellulose, e.g. cellulose acetate, propionate, butyrate or nitro-acetate, and methyl, ethyl and butyl celluloses are specially valuable. The pile fabric may be made of regenerated cellulose artificial silk or natural silk, but preferably the pile is made of cellulose acetate or other organic derivative of cellulose. Pile fabrics having a back of cotton, linen or other natural or regenerated cellulose material may be employed when it is desired to stick the laminated product to a surface of wood &c. Sheet material may be fixed to one or both faces of a double-faced velvet. The laminated materials may be used for lamp shades, for the decoration of drums, for table tops and as wall decorations in bathrooms. In an example, a cellulose acetate sheet material is sprayed with a softening liquid and a crushed pile fabric having a cellulose acetate pile and a cotton backing is then pressed against the sprayed side of the sheet material.

Abstract: 627,294. Electroplating. CLEVELAND GRAPHITE BRONZE CO. April 8, 1946, No. 10757. Convention date, April 12, 1945. [Class 41]  A substantially uniform layer of metal, e.g. 0.005 inch or less thick, is deposited upon the concave surface of a semi-cylindrical article such as a bearing shell by interposing between the anode 16 and the article 1, Fig. 4, which forms the cathode, an insulating barrier, such as a flat plate 15 disposed across the concave surface, extending from lateral edge 1a to lateral edge 1b, having a longitudinal slot 8, and being otherwise impervious to the passage of the current. The slot has a width of approximately 25 per cent or less of the diameter of the article and is disposed parallel with and equidistant from the lateral edges 1a and 1b. To prevent deposition of metal on the convex surface of the article, this latter may be surrounded by an insulating box 21, 22, Fig. 9, one side of which is formed by the barrier 15 so as to form with the convex surface a fluid-tight chamber 17. The box is wholly immersed in the electrolyte in tank 25. In a modification, the electroplating tank has an intermediary insulating barrier such as 15, the article 1 being placed so that the straight and curved edges are firmly seated against the barrier and the bottom of the tank, the centre line of the article being lined up with the centre line of the slot in the barrier and the length of the slot being not greater than the height of the article. Electrolyte is introduced into the tank through a supply inlet in the bottom and rises in the tank, contacting the concave surface of the article and flows over the top of the barrier and the article and is carried away through an opening in the bottom of the tank, there being little or no contact of the electrolyte with the convex surface of the article 1 on account of the " weir " effect of the flow thereover.

A machine for forming sheet rubber into rolls or dollies comprises a conveyer, means for shearing a length of rubber from a sheet carried by the conveyer, means for engaging the sheared edge, of the sheet and turning the leading portion of the sheet outwardly from the conveyer surface, and a member extending longitudinally over and spaced from the conveyer surface to frictionally contact the turned leading portion of the sheet, movement of the sheet causing the leading portion thereof to roll upon the member and form a dolly. Conveyer belts 1, supported on drums 2, are driven by chains 4 on sprockets 3 attached to the drums 2. Shearing members 6, 7, 8 with serrated trailing faces 12a, shearing edges 10 and skid bearing faces 11a, 11b are attached transversely to the conveyer belts 1. A pivoted shearing member 13 with a shearing edge 16 and skids 17, is attached to links 14 to a main frame 5 and is situated above the conveyer belts 1, so that the shearing edge 16 co-operates with the shearing edges 10 of the shearing members 6, 7, 8, the action of the skids 17 on the skid bearing surfaces lla, 11b ensuring that the cooperating shearing edges do not contact each other and jam. The shearing member 13 has a face 21 and an upper plate 22 with a face 23. After the shearing of the rubber sheet, these faces 21, 23 combine to turn outwards and roll upon itself the leading edge of the rubber sheet being conveyed on the conveyer belts 1. The rubber sheet then passes under the shearing member 13 and its rolled leading edge engages with a stationary rolling member 24. Further movement of the rubber sheet rolls the sheet against the underside of the rolling member 24 until a dolly is formed. The shearing edges 10, 16 again co-operate, shearing the trailing edge of the rubber sheet, the process then recommences and the rolled sheet drops off the conveyer end. The rolling member 24 is pivoted. at its forward end to the main frame 5, by links 25, and slides longitudinally at its rear end by rods 29 attached to it and acting on brackets 30 on the main frame 5. A modification is described in which the shearing member 13 is combined with the rolling member 24, the whole being spring mounted at its leading end.
