Abstract

529,754. Asymmetrically - conducting resistances; RUPP, H. June 7, 1939, No. 16707. [Class 37] [Also in Group XXXIX] Into the surface of a semi-conducting layer b of a dry rectifier on a base a, is embedded partly a series of wires e, insulated at d as by oxiding, to act as a grid upon which a varying voltage may be impressed to vary a current passing through the assembly. In the example the semi conductor is selenium and the wires are of nickel. Specifications 500,342 and 500,344 are referred to.
