Abstract

551,698. Asymmetrically-conducting resistances. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., THOMPSON, L. E., and JENKINS, A. Sept. 2, 1941, No. 11196. Addition to 534,043. [Class 37] The composition of the counter-electrode of a selenium rectifier as in the parent Specification is modified by the addition of a small proportion, e.g..3 per cent of mercury.
