Abstract

534,043. Asymmetrically-conducting resistances. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., THOMPSON, L. E., and JENKINS, A. Oct. 13, 1939, No. 27862. [Class 37] The counter-electrode of a selenium type rectifier is composed principally of tin, cadmium or an alloy of these metals to which has been added a small quantity, e.g. 0.1 per cent. of thallium. Specification 523,673 is referred to.
