Abstract: An electron discharge tube has its cathode carried by a supporting structure constituted by a closed hollow container which is in good heat exchanging relation with the cathode. In the container is a quantity of sodium, potassium, caesium, rubidium, lithium or an alloy of two or more of these metals having a boiling point equal to the desired cathode operating temperature. In operation the container acts as a boiler and condenser for the material.

Abstract: A directly heated dispenser-type cathode for microwave tubes and the like, the cathode being formed by a solid electrically conductive substrate, such as tungsten wire, the surface of which has bonded thereto a porous layer of a refractory metal whose pores are impregnated with an electron-emissive material having a low work function, such as barium oxide.
