Title: Innovations by Thomas R Thoman
Introduction
Thomas R Thoman is a notable inventor based in Ridgeville, OH (US). He has made significant contributions to the field of high-temperature induction furnaces. With a total of 2 patents, his work showcases innovative solutions to complex engineering challenges.
Latest Patents
One of his latest patents is an induction furnace designed for operation at temperatures exceeding 3100° C. This advanced furnace features a cooling assembly that is selectively mounted to the upper end of the furnace wall. The cooling assembly includes a dome that is actively cooled by water coils. During the cool-down phase of a furnace run, cooling initially occurs naturally through conduction of heat away from the hot zone. Once the temperature within the furnace hot zone reaches approximately 1500° C., a lifting mechanism mounted to the dome raises a cap of the furnace slightly. This allows hot gases from the hot zone to mix with cooler gas in the dome, significantly speeding up the cooling process. This design reduces cool-down times without the need for complex cooling mechanisms that require periodic replacement. Additionally, the life of the graphite furnace susceptor at high operating temperatures is enhanced by surrounding it with a barrier layer of flexible graphite, which inhibits evaporation. Witness disks placed within the susceptor provide an accurate temperature profile of the hot zone.
