Abstract

623,163. Asymmetrically-conducting resistances. LUCAS, Ltd., J., SILMAN, H., and FREEMAN, A. April 23, 1947, No. 10890. [Class 37] A selenium rectifier has magnesium incorporated in the counter electrode to enable the electro-forming to be expedited and to improve the completed rectifier element. The amount of magnesium is stated to be not critical, amounts varying between 1 and .5 per cent giving optimum results.
