Abstract
415,009. Valve circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 13, 1933, No. 16023/34. Convention date, Jan. 26, 1933. Divided on 414,051. [Class 40 (v).] The effect of changes in grid-bias, due say to automatic volume control, upon the tuning of ganged amplifiers is neutralized by the insertion of a coupling-resistance Rf common both to the grid-cathode and anode-cathode circuits. The impedance of Rf has the same frequencycharacteristic as the inter-electrode valve capacity Cgf, but is of opposite phase.
