Abstract

341,644. Coils. WHITESMITH, I. N., 20, Queen's Road, Urmston, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. Nov. 30, 1929, No. 36803. [Classes 35 and 38 (ii).] Paper &c. 2 used for separating layers of wire 1 in coils for transformers, wireless inductances or other electrical a p p aratus extends beyond the edge of the coil. The space is filled with thermo-plastic powder such as bakelite which is compressed and consolidated under heat in a mould 3. Space may be left round the sides of the coil winding 5 in the mould to allow of the formation of a bakelite covering.
