Patent GB-701153-A (GB)
Title: Improvements relating to electrical insulating and sealing preparations
Inventor: HAMPSON HARRY REGINALD
IPC: H01B3/42
Filed: 1950-02-20
Abstract: An electrical insulating and/or sealing material comprises:-Ethyl cellulose 45-55 per cent., sebacic acid oil-modified alkyd resin 10-20 per cent., turbine oil 15-25 per cent., and a non-drying oil (e.g. castor oil) 10-20 per cent., together with a trace of stabilizer (e.g. gallic acid or menthyl phenol).  In preparing the compound the first four constituents may be heated to 190 DEG C. for 3 hours with thorough mixing and then the stabilizer added and stirring continued for a further half hour.  The product may be poured into moulds and allowed to solidify by cooling.  At a temperature of 190 DEG C. it has the consistency of hot treacle and can then be applied to any article by a simple dipping operation, any "flash" being readily peeled off when cool enough to handle.  When cold, the composition adheres strongly to surfaces of metal, painted metal and fabric and forms a moisture-proof seal.  It adheres less strongly to such surfaces at a temperature between 80 DEG  and 90 DEG C. and can then be peeled off cleanly.  The compound is particularly suitable for insulating electrical apparatus, such as the stators and rotors of dynamos or motors, and may be applied by simply dipping the article or part of the article into a vat of the compound maintained at 190 DEG C.  The parts to be insulated may first be taped and varnished.

Patent GB-579183-A (GB)
Title: Improvements in the manufacture of hollow filaments
IPC: D01D5/247
Filed: 1944-03-09
Abstract: Hollow filaments are obtained by extruding into an aqueous coagulating medium at a temperature of at least 40 DEG  C. a solution of a hydrophobic synthetic linear polymer in an organic solvent miscible with water and containing dispersed therein a substance capable of generating gas in contact with the coagulating medium, the concentration of the organic solvent in the coagulating medium being limited so that the swelling effect of the coagulating medium on the polymer is insufficient to cause cementing of the filaments at points where they are pressed together.  The coagulating medium may be acidic or alkaline.  When sodium bicarbonate or calcium carbonate is used as the gas-producing substance, the coagulating bath is made acidic.  Ammonium chloride and ammonium sulphate require the coagulating bath to be alkaline. The filaments may be made from polyvinyl chloride, chlorinated polyvinyl chloride, vinyl acetate-vinyl chloride copolymers, vinyl chloride-acrylo-nitrile copolymers.  The solvent may be acetone, dioxane, or tetrahydrofurane.  The filaments may be produced with or without stretching.  They may be cut to staple fibre, spun and knitted or woven.  They may be used in the production of padding p  or insulating material.  Specification 580,370, as open to inspection under Sect. 91, is referred to.
