Abstract

564,980. Asymmetrically-conducting resistances. STANDARD TELEPHONES & CABLES, Ltd. Oct. 22, 1943, No. 17422. Convention date, March 15. [Class 37] The selenium layer in a rectifier contains thallium, (preferably oxide or chloride, .001 to .1 per cent by weight). and a halogen, preferably chlorine, combined with the selenium. Specifications 472,961 and 541,893 are referred to.
