Title: Improvements in or relating to fusible blanket compositions for covering molten zincin galvanizing
IPC: C23C2/30
Filed: 1943-07-27
Abstract: 567,191. Fluxes. ABBEY, A. (Dewey & Almy Chemical Co.). July 27, 1943, No. 12240. [Class 82 (ii)] A fusible composition for covering molten zinc baths which form zinc oxide during use comprises an alkali-metal chloride (e.g. potassium chloride), zinc chloride, ammonium chloride, and zinc oxide, which zinc oxide is either in the composition originally or is introduced therein from the bath. The proportions of ammonium chloride, alkali-metal chloride, and zinc chloride are such as to give an initial fusing point below that of zinc, and the proportion of alkali-metal chloride to zinc chloride being such as to maintain the fluidity of the composition after the partial or complete exhaustion of the ammonium chloride. The composition may consist of potassium chloride 35 per cent, ammonium chloride 4.6 per cent, zinc oxide 1.1 per cent, and zinc chloride 59.3 per cent. A regenerating composition for the said fusible composition, for use when the latter becomes or tends to become stiffened by accumulation of zinc oxide is formed by the fusion of alkali-metal chloride, zinc chloride, and ammonium chloride, with or without zinc oxide, the ammonium chloride being much in excess of the proportion of ammonium chloride in the original fusible composition. Specification 416,236 is referred to.

Title: A process for coating rigid sheet materials with thermoplastic synthetic resins
IPC: B29C43/00
Filed: 1957-04-23
Abstract: Rigid sheet materials coated with a thermoplastic synthetic resin are produced by scattering the synthetic resin in the form of granules or a pre-gelled powder on to the sheet material, placing the sheet material between the heatable platens of a press and applying heat and pressure.  The granules are defined as being obtained by kneading the synthetic resin with a plasticiser and, if desired, other additives, e.g. stabilizers, fillers and pigments, at an elevated temperature, e.g. about 120 DEG  to 170 DEG  C., until a homogeneous mixture is obtained and then disintegrating the mixture into regular or irregular particles.  Pregelled powders are defined as being obtained by mixing the resin in powder form with plasticiser and, if desired, other additives at a lower temperature, e.g. about 100 DEG to 120 DEG  C., as described in Specifications 653,965 and 654,477, [both in Group IV (a)].  The sheet material may be wood fibre insulating sheet or plywood and may be pre-compressed before the resin particles are scattered thereon.  The synthetic resin may be a vinyl chloride polymer which may be mixed with dioctyl phthalate, white lead, calcium stearate and pigment in the formation of the granules or pregelled powder.  The temperature during the pressing step may be between 150 and 180 DEG  C., and the pressure applied is greater than the vapour pressure of any volatile constituents released from the sheet material under the influence of heat, e.g. 15 to 35 kg./cm.2 when wood fibre insulating sheets are used.
