ABSTRACT:
An apparatus for treating articles by heat and pressure and then cooling by forced circulation may have a pressurized heated chamber for holding such items to be treated, this chamber being positioned within a cooled, pressure sustaining enclosure, a pressure developing mechanism may be positioned at one side of this enclosure and may include a valving function for selectively drawing inert gas into the enclosure and into the heated chamber the heated chamber including a wall having a plurality of openings spaced throughout into the item-holding chamber, a passageway may extend from one end of this item-holding chamber, past the cooled area of the sustaining enclosure and onto the pressure developing mechanism whereby the valving function may be selectively operated allowing the pressure developing mechanism to circulate the gaseous medium within the apparatus more evenly and uniformly over all items held within the chamber, the heating operation of the chamber being selectively disabled during this circulation whereby a rapid and even cooling of the items is effected.
