Abstract

742,058. Fibrous separator plates for electric accumulators. BRITISH FIBRAK SEPARATOR CO., Ltd. July 31, 1953 [Oct. 10, 1952], No. 25502/52. Drawings to Specification. Class 96. Separator plates for electric accumulators are formed from paper pulp impregnated with resin as described in Specification 672,122, the material being deformed about parallel ribs from the middle outwardly towards each edge, heat and pressure being applied to cure the resin only in the deformed areas ; the crests of the ribs being then coated with a strong resin solution, and all uncured resin then cured. The material may be impregnated with a wetting agent, e.g. turkey red oil. A doctor &c. removes resin from the ribs of the forming-drum, which ribs may comprise encircling copper bands, scarf-jointed and secured by set-screws.
