Title: Innovations by Clark W. Keller
Introduction
Clark W. Keller is an accomplished inventor based in Leechburg, PA (US). He has made significant contributions to the field of metallurgy, particularly in the alloying of metals. With a total of 2 patents, Keller's work has advanced the methods used in metal processing.
Latest Patents
Keller's latest patents include a method of alloying feed material into molten metal. This innovative approach allows for the operation of a known 'spark cup process' without the spark cup itself. By accommodating the violent fluctuations in the melt surface, the electric arc can be maintained continuously. This continuous operation generates enough plasma to permit the addition of up to 1000 lb/hr of superheated feed material to a flowing stream of melt, which effectively assimilates the feed material.
Another notable patent is the commutation means for on-line alloying. This apparatus is designed to commutate electrical current to an electrically conductive rod of an alloying element during its feed into molten metal. The system includes a power supply capable of melting the free end of the rod into the molten metal. It features a pair of parallel adjacent shafts with commutation wheels that engage the rod, ensuring intimate electrical and physical contact. Additionally, stationary brushes supply current to the shafts, facilitating the alloying process.
