Filed: 1920-07-09
Abstract: 147,816. British Thomson - Houston Co., (Assignees of White, W. C.). Oct. 11, 1917, [Convention date]. Drawings to Specification. Vacuum tubes.-Thermionic valves for receiving wireless signals have their anode circuits energized by the same battery as is used for heating the filaments, the voltage being preferably about six volts. The anode is formed of a metal which is electro-positive with respect to the filament, the anode being preferably of nickel and the filament of tungsten. The filament is surrounded by a helical wire grid, preferably of tungsten, and a cylindrical anode, the distances between the electrodes, particularly between the grid and filament, being small. The bulb is thoroughly baked and exhausted, and during this process the anode is heated, preferably by passing current between it and the grid, in order to expel impurities and oxides. The temperature of the filament is such that the initial velocity of the electrons is sufficient to enable them to reach the anode without any external potential in the anode circuit, and the fact that the anode material is electro-positive in relation to the filament material increases the current flow. The current is also increased owing to the anode being at a greater potential than any part of the filament, due to the potential drop across the resistance 9 in the filament circuit.
