US4191598A - Jet recirculation method for vacuum

A method and apparatus for recirculation of atmosphere in a vacuum furnace which comprises a recirculation loop in which there is a low pressure line from the furnace chamber leading to a recirculation pump which pumps the recycled gas at a higher pressure to a high pressure line back into the furnace chamber. A means to analyze the furnace atmosphere is in communication with the high pressure
