Abstract: 747,484. Thermionic valves. M-O VALVE CO., Ltd., and COOK, K. G. Feb. 3, 1954 [Feb. 3, 1953], No. 3092/53. Class 39 (1). A gas-filled thermionic valve, such as hydrogen thyratron, has a baffle 11 disposed between the cathode 9 and another electrode, such as grid 4, on to which evaporation of electron-emissive material from the cathode could occur in substantially straight lines in the absence of the baffle, the baffle screening the other electrode substantially completely from the cathode and not being directly connected to any other electrode, and a capacitor 13 of say 0.01 ÁF is electrically connected between the baffle and the other electrode; preferably a resistor 14 of say 500 ohms is electrically connected between the baffle and the cathode. Thus when the tube is switched off, no glow discharge can occur from the negative grid 4 to the cathode because the baffle 11 intervenes; and no such discharge can occur from the baffle itself because there is no direct current path. Again, when the tube is switched on, the baffle is held by the capacitor substantially at the same potential as the grid and thus does not shift the striking point into the positive region as with known baffled tubes. The resistor ensures that the baffle does not permanently depart from cathode potential. The arrangement may also be applied to a gas-filled diode.
