Abstract

381,340. Condensers.BRITISH CELANESE, Ltd., 22, Hanover Square, London. Oct. 13, 1931, No. 28405. Convention date, Oct. 13, 1930. [Class 38 (ii).] Condensers are insulated by wrappings of artificial filaments or yarns of organic derivatives of cellulose, e.g. cellulose acetate, formate, propionate, butyrate, or ethyl, methyl, benzyl cellulose, the filaments or yarns being coalesced at least partially by pressure or heat. Solvents such as acetone, tetrachlorethane, diacetone alcohol and mixtures of methylene chloride with ethyl or methyl alcohol; swelling agents such as ethyl or methyl alcohol, mono-ethyl ether of ethylene glycol, or a mixture of a solvent such as acetone or diacetone alcohol with benzene ; and plasticizers such as, among others, triphenyl phosphate, tricresyl phosphate and triacetin may be used to cause or assist coalescence. Specification 311,241, [Class 120 (ii), Spinning, twisting, &c.] is referred to.
