Abstract
607,443. Valve relay circuits. PELLE, P. Feb. 4, 1946, No. 3524. Convention date, Feb. 15, 1945. [Class 40 (vi)] In a thermionic valve relay circuit for relaying telegraph signals, impulses from a local source are applied to the valve control grid to determine the instant at which the output from the anode is applied to one or other of the windings of a differential polarized relay connected in the anode circuit. In the Figure, modulation signals are applied to relay R1, the contacts t1 and r1 of which connect the anode of valve L to H.T. supply via one or other of the coils of the polarized and differential relay R2. Impulses, which may be derived from a local source I are applied to the grid of valve L so that this valve periodically conducts. The contact a2 of relay R2 connects either positive or negative potential to a line C. The armature of relay R2 is stable in either position, so that when relay R1 operates, the change in potential applied to the line C occurs when the next impulse is applied to the grid of the valve. Modulation applied to relay R1 is thus repeated to line C, but the instants of change-over are made to correspond with one of the impulses applied to the control grid.
