Abstract

565,321. Asymmetrically-conducting resistances. STANDARD TELEPHONES & CABLES, Ltd. Nov. 19, 1943, No. 19379. Convention date, Nov. 27, 1942. [Classes 37 and 41] A " blocking layer " is deposited by electrolysis on the selenium of a rectifier by making it the cathode in an electrolyte of a solution of selenium dioxide (1 per cent to 80 per cent by weight).
