Latest Patents

Buxbaum's latest patents include a thermionic cathode of high emissive power for electric tubes. This invention features a reactionless thermionic cathode that consists of a metallic or ceramic support and an alloy, preferably an intermetallic compound, containing the emission-promoting element along with a metal from the group of the VIIIth vertical row of the periodic table and rhenium. The preferred activation substances are platinides of elements with a low electron work function, predominantly barium and lanthanum. The manufacturing process involves wet-mechanical, cataphoretic, or electroplating application of the activation substance to the support or infiltration of a porous support with a pore volume of at least 10%. High emission current densities are achieved at relatively low operating temperatures. Another patent focuses on hot-cathode material in wire or sheet form, which comprises a high-melting carrier metal, an oxide activator, and a carbide reducing agent. This material is designed to ensure that the rate of diffusion of the activator from the core zone is equal to or greater than the loss of activator from the surface layer.
