Abstract

386,668. Valve circuits. MORINO, O., 36, Via XX Settembre, Genoa, Italy. July 8, 1931, No. 19636. Convention date, July 8, 1930. [Classes 39 (i) and 40 (v).] A thermionic valve has a number of auxiliary electrodes 4 .. 7 in addition to the usual cathode 3, control grid 2, and anode 1 ; and tunable circuits 8, 9, 10 are connected between the auxiliary electrodes and adjustable points on a polarizing source. The Specification indicates bv means of resonance curves the manner in which the tuning of the auxiliary circuits may be regulated to reduce interference in radio reception, and to produce an even amplification of a band of frequencies. Reference has been directed by the Comptroller to Specifications 234,809 and 303,008, [both in Class 40 (v), Wireless signalling &c.].
