Abstract

1,077,575. Accumulators. SOCIETE DES ACCUMULATEURS FIXES ET DE TRACTION. Oct. 16, 1964 [Oct. 18, 1963], No. 42432/64. Heading H1B. A separator consists of porous, material formed from. woven, or felted fibres, at least some of which are polyamide fibres and, is impregnated with carboxymethyl cellulose or derivatives, thereof in such amount as to promote flow of, electrolyte and to preserve porosity. Multilayer, fabrics may he used and may contain cellulosic fibres. The separator is for nickel-cadmium cells haying thin electrodes and separators.
