Abstract

226,895. Mitchell, G. A. Oct. 6, 1923. Vacuum tubes. - An additional valve is connected directly to one of the valves of a set, i.e., plate to plate, grid to grid, and filament to filament, for the purpose of amplifying the signal to be transmitted or received. A valve holder for this purpose consists of a strip or sheet 1 of insulating material on which two or more sets of valve legs are mounted, corresponding, valve legs being connected to one another by wires. One of the sets of valve legs may be replaced by sleeves 9 inserted in the insulating material, so that the pins of a valve inserted therein may extend below the strip and may be then inserted in the holder in the set. Alternatively, the sleeves may be dispensed with, the wires 4 connecting the additional holder being formed into loops which engage the valve pins when they are inserted in the holes in the strip. Reference has been directed by the Comptroller to Specifications 152,811, 153,553, 158,901, 164,105, and 167,584, [all in Class 40 (v), Wireless signalling &c.].
