Abstract
515,800. Valve amplifying circuits. BAIRD TELEVISION, Ltd., and MAITLAND, C. E. June 13, 1938, No. 17508. [Class 40 (v)] An intervalve coupling arrangement for very high frequencies comprises the inductance 2 of a tuned circuit and a resistance 3 connected between the anode of the first valve 1 and the high-tension source, the junction of the elements 2, 3 being connected through a lowreactance condenser 4 and an inductance 5 to earth, and the junction of elements 4, 5 being connected through an inductance 6 to the grid of the second valve 7. The inductances 2, 6 may be tuned by the inherent inter-electrode capacities 8, 9 of the valves 1, 7, respectively. Damping resistances may be added in series or shunt to the tuned circuits 2, 6 and the inductance 5 to give a wide pass-band of uniform response.
