Title: Process for the production of composite sheet structures having a polyolefine base
IPC: C08J7/052
Filed: 1959-11-12
Abstract: 910,027. Coated polyolefine sheets; laminates. DYNAMIT NOBEL A.G. Nov. 12, 1959 [Nov. 14, 1958], No. 38464/59. Class 140. Coated high molecular weight polyolefine sheet is produced by treating the polyolefine sheet with gaseous chlorine and thereafter applying to the treated surface a solution of after-chlorinated polyvinyl chloride in an organic solvent to form a coated sheet capable of being firmly bonded to a sheet of plasticizer free polyvinyl chloride. The high molecular weight polyolefine sheet may be formed from a polyethylene or polypropylene of high molecular weight. The solution of after-chlorinated polyvinyl chloride may contain a small quantity of plasticizer, and as the organic solvent, a mixture of toluene with acetone, butanone, or methylene chloride. A sheet of plasticizer-free polyvinyl chloride, which may be precoated with after-chlorinated polyvinyl chloride in the manner described for the polyolefine sheet, may be applied, e.g. by extrusion, to the afterchlorinated polyvinyl chloride coated polyolefine sheet by hot pressing or rolling, in what may be a part of a continuous process, to form a composite sheet structure. The after-chlorinated polyvinyl chloride should have a chlorine content of 65% or more.

Title: Process for producing veneer having a combination of wood grain patterns and an article product therefrom
IPC: B27L5/00
Filed: 1974-09-03
Abstract: 1456889 Veneers T SADASHIGE 3 Sept 1974 [3 Oct 1973] 38506/74 Heading B5L A veneer comprises a sheet of wood having disposed therein, and secured by adhesive thereto, a piece of wood with the wood grain patterns of the sheet and piece relatively discontinuous. Fancy plywood is produced by securing said veneer to a substrate. the sheet/piece adhesive may be coloured with dyes, pigments or mixtures thereof, e.g. alazarine red S, methylene blue, azo and cyanine type dyestuffs, titanium white, red iron oxide, chrome yellow. Alternatively, the adhesive may be transparent so that the substrate colour or pattern (e.g. wood grain), or a paper, metallic film or further veneer sandwiched between the veneer and the substrate, may be viewed through the adhesive. In Figs. 1A, IF, the veneer is produced by cutting, by router or fretsaw, a piece 12 (e.g. cylindrical) from a wood block 10, smoothing the piece, as by sand paper, and replacing and securing by adhesive the piece in the hole from which it was cut but in a different position, e.g. rotated or inverted. Thereafter, the block is sliced into veneers 14, 16 including parts of both the piece 12 and the block 10. In Figs. 2A-Figs. 5C and Figs. 8A-8F (not shown), pieces cut from the same or different blocks (of the same wood or different woods) are placed and secured in holes different from those from which they were taken when cut. In Fig. 6A, the veneer is formed from a marquetry arrangement of interfitting symmetrically shaped pieces from blocks of different woods which pieces are secured together and into a block 40. In Figs. 7A-7C (not shown), the blocks comprise glued composites and the holes and pieces are cut respectively across and parallel to the grains of the composites. The veneer slicing may be effected normal or at an angle to the routing direction. Preferably, to avoid distortion and splitting due to dimensional change stresses, the whole process is effected at or above the fibre saturation point. Woods refered to include teak, rosewood, walnut, red oak, birch. Adhesives referred to include vinyl acetate emulsion, ethylene glycol dimethacrylate, and phenolic, urea, gum, melamine, epoxy, polyester, cyano acrylate, and polyurethane resins, and of these those which are of the underwater curing type are preferred.

Title: Cutting master and method of making a cutting master for abrasion machining
IPC: B23H1/04
Filed: 1974-09-13
Abstract: 1486802 Abrading tools T J O'CONNOR 13 Sept 1974 [14 Sept 1973] 40046/74 Heading B3D For an abrasion machining operation in which, e.g. a carbon electrode of a required form is produced by engagement with a cutting master having a complementary form, a female cutting master 10 is produced by providing an abrasive surface 14 on a body 15 of rigid material which surface is complementary to the required form but different in size therefrom in two mutually perpendicular directions by a predetermined amount related to an orbital movement caused between the cutting master and workpiece during the machining operation, which thereby requires a flat portion 30 on the abrasive surface. The master has means 40 to enable it to be attached to a feed means, and a manifold 48 for supplying a flushing gas or liquid, e.g. kerosene, water, air, or vacuum. Various methods are described for producing the cutting master 10. In Figs. 3-6 (not shown) a model (60) of shape required is used in an electric discharge machining operation to form a recess (52) in a steel block (54). The recess is formed oversize by an orbiting motion between the model (60) and block (54) during machining, e.g. oversize in dimensions 22, 24 but the correct size in dimension 26. The block (54) is then used as a cutting master to produce a new electrode (64). In the electric discharge machining operation, if the model (60) or cutting master is not electrically conductive, it may be spray coated with aluminium or copper. In Figs. 7-9 (not shown) a female cutting master is produced by casting a settable material (86), having abrasive particles dispersed therein, over an oversize model (90). The settable material may be an epoxy resin with sand filler. The abrasive material may be emery, carbide chips, glass, industrial diamonds. In Figs. 10-12 (not shown) a cutting master is formed by a plurality of small diameter rods (96) with sharp ends which are allowed to engage around the shape of a model (106) and are then fixed in position by a settable filler, e.g. lead, babbitt, epoxy plastics, tin, zinc. In Figs. 13-18 (not shown) model (112) has cast over it an aluminium model, which is then used to cast an electrode model (120), e.g. of copper. This copper model is used in electrical discharge machining to produce, with orbiting motion, an oversize female model (122). This model is used to cast an oversize male model (126) and an oversize female cutting master (130) is cast over the model (126). In Figs. 19-22 (not shown) a model (136) of the required shape is plunged into a settable material (140) at the same time as it is given orbital movement to produce the cutting master (146).
