Abstract

439,531. Electrolytic condensers. DUBILIER CONDENSER CO. (1925), Ltd., Victoria Road, North Acton, London.- (Assignees of Dubilier, W., and Oppenheimer, J. ; 10, East 40th Street, New York, U.S.A.) Oct. 19, 1934, No. 29946. Convention date, Oct. 21, 1933. [Class 37] An electrolyte comprises a mixture of a weak acid such as boric acid or an oxide, anhydride or salt thereof, ammonium hydroxide, or a hydroxide or oxide of an alkali metal or ammonia and a polyhydroxyl-alcohol such as ethylene glycol heated to about 140-150‹ C. to which is added gum tragacanth. The mixture may be diluted with water or a monohydroxyl alcohol. Specification 439,530 is referred to.
