Abstract
549,484. Valve circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 28, 1939, No. 26825. Convention date, Oct. 26, 1938. [Class 40 (v)] Grid bias, particularly. for a modulator, is obtained from a resistance D, such as a copper oxide rectifier, that has a substantially constant voltage with variable current characteristic. The grid bias thus remains constant irrespective of large anode current fluctuations.
