Abstract

606,763. Asymmetrically-conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 18, 1946, No. 1758. Convention date, May 7, 1941. [Class 37] The leakage current in selenium rectifiers is reduced by passing current in the blocking direction through the rectifier whilst the latter has a temperature exceeding the normal operating temperature. The required temperature may be obtained by a furnace, insulating bath, or as preferred, heating by contact with an externally heated supporting plate. Suitable apparatus consists of a rectifier plate 1 and a block 2 of high thermal capacity, maintained at the required temperature by heating element 3. Contact member 4 consisting of two parallel metal plates between which are located resilient contacts 5 to ensure satisfactory electrical contact over the whole rectifier plate is suspended from a supporting plate 6, the latter controlled by lever 7 supported by column 8. Frame 12 is resiliently suspended from plate 6 and holds plate 1 on to block 2. Contact member 4, contacts 5 and block 2 are mutually insulated.
