摘要： A gas injector including in which a gas is passed through high-voltage/low-current electrical discharges before being discharged into the chamber of a thermal treatment furnace. The electrical activation of the gas accelerates desirable reactions between the gas, gases in the furnace chamber, and the chamber workload. Preferably, a hot electrode is electrically charged and the other parts of the gas injector and the furnace are grounded. Also provided is a method for activating an atmosphere within the reaction chamber of a controlled-atmosphere reactor.

摘要： Apparatus that prevents the buildup of frost or ice on plumbing in a cryogenic delivery system (10) and on cryogenically cold surfaces (14a) exposed to ambient air. The plumbing is sealed within a casing that includes a microporous membrane (14). A purge gas stream is fed into the casing at an effective pressure, causing the purge gas to diffuse through the microporous membrane (14) and prevent frost or ice formation on an exterior surface (14a) of the apparatus or around a cryogenic discharge nozzle (420).

摘要： A fluid spray device system (1) that maintains a resultant fluid discharge, or a material onto which the resultant fluid is discharged, within a predetermined range of a set-point temperature by regulating the flow rate of a throttling gas using a proportional valve (22). The resultant fluid has throttling gas and cryogenic fluid components. Both the throttling gas and cryogenic fluid are preferably supplied from a single tank (11) and the cryogenic fluid supply is pressure-regulated and includes a triaxial delivery hose (33) having a return line with a back-pressure regulator (54).

摘要： Described herein are a method, an apparatus, and a system for metal processing that improves one or more properties of a sintered metal part by controlling the process conditions of the cooling zone of a continuous furnace using one or more cryogenic fluids. In one aspect, there is provided a method comprising: providing a furnace wherein the metal part is passed therethough on a conveyor belt and comprises a hot zone and a cooling zone wherein the cooling zone has a first temperature; and introducing a cryogenic fluid into the cooling zone where the cryogenic fluid reduces the temperature of the cooling zone to a second temperature, wherein at least a portion of the cryogenic fluid provides a vapor within the cooling zone and cools the metal parts passing therethrough at an accelerated cooling rate.
