Title: Discovering the Innovations of Donald R. Stoner
Introduction
Donald R. Stoner is an accomplished inventor based in Murrysville, PA, with a remarkable portfolio that includes five patents. His contributions to the field have significantly advanced technological processes, particularly within the realm of heat exchangers and metallic tube stress relief.
Latest Patents
Among his latest innovations is a patented process for thermally stress-relieving a metallic tube. This process involves a meticulous approach where a small diameter radiant heater is inserted into the open end of a metallic conduit. The heater positions itself adjacent to the stressed portion, heating it to temperatures between 1150°F and 1500°F for a specified duration, depending on the wall thickness. By measuring the emissivity of the stressed section, this process ensures effective thermal stress relief, which is crucial in components such as the U-bends of heat exchanger tubes made of Inconel 600, commonly used in nuclear steam engines.
Additionally, Stoner has patented a metal brazing sleeve featuring a ceramic flux band. This innovation involves adhering a powder flux to the sleeve with a tacky adhesive and subsequently melting it to form a hard and adherent band. This design protects against abrasion during insertion into tubes and enhances the performance of the braze.
