Vacuum Oven Chamber

      Disclosed is an invention of a chamber which will withstand
temperatures of 500 degrees centigrade and hold a vacuum state of 10
to the -3 tores.

      The materials used must be able to operate under 500 degrees
centigrade temperatures and have non-out gassing properties.  There
are a number of through the wall holes required for thermocouples,
vacuum connections, heater rods and four located in the top of the
chamber for moving pistons which are used to apply vertical pressure
to the product being cured.  All external holes must be sealed and
hold a vacuum state of 10 to the -3 tores.  The thermocouples and
heater rods are sealed off using a swag locking device.  The piston
holes are sealed off by using a metal bellows.  An easy access hinged
door is used along with an O ring sealing device.  The overall
enclosure consists of three quarter inch thick stainless steel which
maintains temperature and provides the required vacuum wall support.
A snake like cooling coil, for chilled water flow, is welded to the
outer surface of the chamber to allow and control quick cool down.
