    Abstract: The present invention involves the use of a braze preform (28) for sealing and maintaining a vacuum in an insulation vessel (10). The braze preform (28) comprises particles of a braze material that are at least partially sintered together and at least substantially free of a binder. An assembly is provided for use in a method of manufacturing a vacuum insulation vessel (10). The assembly comprises a metal jacket (12) defining an interior space (20) to be evacuated and one or more evacuation ports (24) formed through a wall of the jacket (12). The evacuation ports (24) provide an opening to the interior space (20). The sintered braze preform (28) is located adjacent to the evacuation ports (24) so as to seal the evacuation ports (24) upon the melting of the brazing material. After the interior space (20) of the jacket (12) is evacuated, the preform (28) can be melted and allowed to solidify and seal the evacuation ports (24). In this way a vacuum can be maintained in the interior space (20).

    Abstract: A method and apparatus using pneumatic pressure and reduced, controlled clamping pressure to provide reliable, high speed pneumatic forming of thin foil workpieces at ambient temperatures without lubricants or cull plates. Forming elements are provided which incorporate a combination of surfaces and features which enable the reduced, controlled net clamping pressures for forming thin foil workpieces, and control of material slip during forming. Thin foil workpieces formed therewith have reduced incidence of tearing and wrinkling of the foil material. The method is capable of fast cycle times and produces minimal waste.

    Abstract: An insulation panel comprises an insulation board of glass fibers and a partially evacuated gas-tight envelope encapsulating the board, where, prior to the evacuation of the envelope, the board has been subjected to a heat setting process in which the board is raised to a heat setting temperature above the strain temperature of the glass but below the softening temperature of the glass and to a pressure applied by opposed platens followed by a quick release of the board from the platens prior to substantial cooling of the board.

    Abstract: A vacuum panel includes a jacket having a bottom that is formed into a "pan" shape. A top is welded to the flanges of the bottom to create a hermetic seal therebetween. A dense glass fiber mat fills the jacket. A getter is strategically located in the panel to absorb residual gases in the panel and maintain the vacuum life. To create the vacuum in the panel, the panel is heated to a specified temperature and time, and evacuated through an opening. The opening is sealed with a braze seal that is melted over the opening.

    Abstract: A pair of forming elements incorporate features which restrain a thin foil workpiece without requiring high or excessive clamping pressures. A retaining step is provided in the second forming element having the forming cavity. It has been found that thin foil workpieces bent over and engaged by contact with the retaining step are secured against slippage with reduced clamping pressures. Moreover, the thin foil workpieces exhibit material draw during forming without the excessive lateral pressure between clamping surfaces that causes wrinkles. Substantially wrinkle-free flanges remain in the formed article.
