Title: Innovations of Louis R. Falce
Introduction
Louis R. Falce is a notable inventor based in Lexington, KY (US). He has made significant contributions to the field of thermal efficiency in dispenser cathodes. With a total of 2 patents, his work has advanced the technology used in cathode ray tubes (CRTs).
Latest Patents
Falce's latest patents include a high thermal efficiency dispenser-cathode and a method of manufacture. The first patent describes a reservoir dispenser cathode structure that features improved thermal efficiency through inner and outer subassemblies. The inner subassembly incorporates a molybdenum heater cup with a tungsten-rhenium alloy cap that is laser seam-welded. The outer subassembly consists of a tantalum support cylinder, which supports the inner subassembly using a three-point suspension system. This innovative design allows for high current density, exceeding 3 Amperes per square centimeter, while maintaining heater power below 1.3 Watts.
The second patent outlines a four-piece dispenser cathode that is easy to manufacture and capable of current densities exceeding 10 Amperes per square centimeter. This design is particularly suited for CRT applications due to its low cost. The cathode features a refractory material reservoir that contains a pellet of tungsten and barium calcium aluminate, sealed by a porous tungsten pellet. The inventive process includes steps for preparing the pellets and assembling the four elements of the cathode.
