ISOSTATH FOR PROCESSING MATERIALS IN FLUID Russian patent published in 2011 - IPC B22F3/04 B22F3/15 

FIELD: process engineering.

SUBSTANCE: invention relates to equipment for material processing by combined effects of temperature and pressure created in gas-fluid system and may be used for compaction of powder materials elastic envelopes at 200 °C and up to 200 MPa. Proposed unit comprises working chamber tightly closed by sealed plugs and communicated via one of said plugs with gas pressure source, heater and vessel for fluid provided with cover. Heating resistor consists of bottom heater arranged above vessel bottom and lateral heater secured on vessel inner wall. Note here that the latter is arranged in working fluid and electrically isolated from the vessel.

EFFECT: higher efficiency, reduced heat loses.
