Patent GB-563589-A (GB)
Title: Improvements in or relating to articles of plastic materials
Filed: 1942-11-19
Abstract: 563,589. Coated fabrics ; compound sheet materials. FINLAYSON, D., and CRAWSHAW, H. Nov. 19, 1942, No. 16373. [Class 140] A method of making sheets and other articles of plastic material in which a plastic of low elasticity is reinforced with textile yarns of the same order of elasticity as the plastic comprises incorporating in a body of the plastic a fabric comprising the reinforcing yarns together with auxiliary yarns, the reinforcing yarns not being interlaced with one another in the fabric and the auxiliary yarns being adapted to hold the reinforcing yarns in the form of a coherent fabric prior to incorporation in the plastic, but to lose their strength in the operation of moulding under pressure. The fabric may have both reinforcing and auxiliary yarns in both warp and weft, the reinforcing yarns not being interlaced but depending for their retention in the fabric upon the auxiliary yarns. The reinforcing and auxiliary yarns may alternate one and one in both warp and weft or one and one in the warp and two and two in the weft. The reinforcing yarns may be a single layer-of parallel yarns held together by parallel auxiliary yarns at right angles. A number of fabric. layers may be used, the reinforcing yarns in each being at different angles. The reinforcing yarns may be at least as elastic as the plastic, and the auxiliary yarns may be woven into the fabric under very light tension so that the reinforcing yarns lie substantially straight, or where the plastic is at least as elastic as the reinforcing yarns, the auxiliary yarns are woven under sufficient tension to give the reinforcing yarns a slightly wavy form. The reinforcing yarns may be regenerated cellulose continuous filament yarns which have been highly stretched or continuous cellulose ester filaments which have been highly stretched and then saponified. The auxiliary yarns may be light continuous filaments of thermoplastic material, e.g. of cellulose acetate or of an interpolymer of vinyl acetate and vinyl chloride. Metallic wires may be interspersed amongst the reinforcing yarns, and may comprise twisted fine wires. The plastic may be applied to the fabric by a bath or by padding, spraying, or spreading, or may be in the form of sheets between which the fabric is sandwiched. Specification 544,442 is referred to.

P. G. or H2, with oxygen produced by the enothermic decomposition of H 2 O 2 , e.g. by a silver catalyst. A supplementary fluid, e.g. water or air, is fed into the combustion chamber 16 under the control of a valve (30), Fig. 1 (not shown). The fuel may be fed continuously or in cycles. As shown a plastics rod 46 is fed by a piston 60 into the combustion chamber 16 to an extent determined by a stop 66 and water is injected through a nozzle 38. In a further embodiment, Fig. 3 (not shown), the combustion chamber (72) is defined by the bore of a plastics tube (68) and water flows into a chamber downstream of the bore through apertures (78) in the wall of the chamber to mix with the combustion gases. A further embodiment, Fig. 4 (not shown), water and fuel injection nozzles (38, 80) project through a refractory combustion chamber lining (54).

Patent GB-407670-A (GB)
Title: Improvements in or relating to the plating, cleaning or etching of articles or metals
IPC: C25D3/02
Filed: 1932-06-10
Abstract: A bath for plating metals by immersion only is obtained by dissolving a suitable metal salt in lignin-containing liquor which is substantially free from cellulose and has been subjected to oxidation.  Oxidation of the liquor may be effected by hydrogen peroxide and/or a halogen preferably in the presence of a catalyst, such as an iron, chromium or osmium salt, or an enzyme such as peroxydase.  Oxidation may also be effected electrolytically.  The ligin-containing liquor may be that resulting from the mild cooking of fibrous material in a sulphite bath.  When a more complete cooking has been employed, the liquor is treated to remove excess of cellulose material by heating and filtration.  The oxidized liquor may be concentrated or evaporated to dryness and restored to its original condition by addition of water.  As an example, copper may be deposited on iron from a bath obtained by dissolving a cupric salt in spent digestion liquor, the cupric salt effecting the necessary oxidation of the lignin material.  Specification 337,405, [Class 2 (iii)], is referred to.
