Abstract
29,839. Jackson, W. J. Mellersh-, [Caldwell, E. W.]. Dec. 27. Vacuum tubes.-In a rectifying vacuum tube of the Villard type, the cathode is arranged to produce a concentrated beam of cathode rays when the vacuum becomes too high to cause generation or admission of gas. In the form shown in Fig. 2, the cathode 62, which is perforated, focusses the rays on to a gas-generating substance spread on a holder 177, which has a weighted arm 61 and may be adjusted in a threaded support by rotating the tube. The substance may be sodium or potassium hydrate but is preferably dry sodium formate. The anode 58 is of small surface and is arranged in a restricted space. In a modification, the gas-generating substance is embedded in a ball of asbestos fibre or the like, held loosely in a spherical carrier so that fresh parts of the surface may be exposed to the rays. The cathode may consist of a coil of aluminium wire or the like carrying a focusing-cup at the end. In a modification shown in Fig. 3, the tube is provided with a well insulated external electrode 66, connected to the anode, which deviates the rays so that they fall on the gas-generating substance 57. In further modifications, the rays fall on a body, which, when heated, allows admission of gas from outside ; or on a porous body normally covered with mercury which is removed by the heat of the rays. Specification 13,966/00 is referred to.
