Title: Paul Fischer: Innovator in Thermionic Cathode Technology
Introduction
Paul Fischer is a notable inventor based in Oakhurst, NJ (US). He has made significant contributions to the field of thermionic cathodes, holding a total of 4 patents. His work focuses on enhancing thionic emission through innovative methods and materials.
Latest Patents
Fischer's latest patents include methods for making thermionic cathodes using oxygen-deficient and fully oxidized materials. One of his methods involves preparing an impregnated cathode with enhanced thionic emission from a porous billet. This is achieved by impregnating the billet with a suitable impregnant in the presence of an oxygen-deficient compound. Additives such as Iridium (Ir), Osmium (Os), and Rhodium (Rh) play a crucial role in increasing emission by generating oxygen-deficient compounds like WO₂. Additionally, intermediate oxygen-sufficient products formed during the chemical reactions can serve as impregnants, provided they generate oxygen-deficient compounds in the presence of the active emissive material.
