Abstract: A nonevaporating getter, which is optionally heatable in operation within an electron discharge vessel, in which the getter material contains at least one metal selected from the group consisting of Zr, Ta, Hf, Nb, Ti, Th and U, and is disposed directly on the insulating layer of the heating means, eliminating the use of an open metal vessel or the like for the getter material.

Abstract: Method and apparatus for producing electrodes capable of receiving considerable cathode bombardment and which are formed so as to remove gas from an electron tube, are disclosed. The electrodes are formed by powdered metallurgy by mixing getter material powders such as zirconium, titanium or other getter material powders with carbon powder such as graphite and then forming the electrodes by pressing the mixture into a mold with a small amount of pressure and sintering in the range, for example, of 800* to 1,400* centigrade to produce the electrodes which have good gas absorption capability and which can be worked with little difficulty.
