Abstract

646,852. Dry-contact rectifiers. STANDARD TELEPHONES & CABLES, Ltd. Feb. 20, 1948, No. 5010. Convention date, Feb. 28, 1947. [Class 37] A process of manufacturing selenium rectifiers comprises subjecting them to the vapours of an aldehyde and to the action of ammonia and/or of a material selected from the group of amines, after heat-treatment and before the application of the counter-electrode. Amines referred to are monomethylamine, dimethylamine, benzinamine, anilin, hexamethylene-tetramine. Specification 633,275 is referred to.
