Abstract

578,050. Asymmetrically-conducting resistances. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and STEVENS, S. A. Feb. 7, 1944, No. 2208. [Class 37] A rectifier baseplate 1 of extremely thin metal (0.02 inches or less) has its edges 2 parallel to the direction of flow of a cooling medium, flanged or otherwise deformed for rigidity purposes. A number of elements having such baseplates may be threaded on insulated spindles and spaced apart by metal washers to form a cellular structure through which cooling air is forced to flow by a fan &c. Specification 509,432, [Group XL], is referred to.
