Autoclave Shelving Fixture

      Disclosed is a uniquely designed five-position shelving fixture
to set material on during the lamination process in an autoclave.

      An autoclave is a large heated and pressurized chamber used to
bond or laminate materials.  In the autoclave process, the material
to be laminated is placed in vacuum bags and then set on the shelving
fixture to allow the heated gaseous nitrogen to provide isostatic
pressure across all faces of the product.

      In the Figure, each material package (1) to be processed is
first placed on a carrier plate (2) and moved to and from the
autoclave shelving fixture with a set of commercially available
overhead forks (3).  The shelving fixture (4) is designed in such a
way to allow these forks to set the carrier plate down on the shelf
(5), with recesses under the shelf to allow the forks to then pull
away from the shelving fixture.  Lightweight removable inserts (6)
provide additional structural support, while allowing easy access for
the overhead forks in and out of the shelving fixture.

      The shelving fixture has been designed to maximize open space
and minimize total mass for optimized heat transfer between the
gaseous nitrogen and the material packages.

      This shelving design allows for full autoclave utilization
(five full shelves of product) while still satisfying all IBM* safety
standards for operator movement of heavy loads.

      The entire shelving fixture can be r...
