Patent number: 8020840Abstract: A versatile clamp which consists, at least in part, of at least one extendable arm, one fixed-length arm, pivotable clamping legs on the distal ends of the fixed-length arm and extendable arm, and locking means; wherein clamp adjustments, by the user, to the extendable arm and pivotable legs are retained by a locking action, which, prevents an inadvertent change of the extendable arm's effective length and the clamping legs' angular orientation from their set positions. The combination of a variable-length extendable arm and variable angular positioning of the legs enable a single versatile clamp to be used in a variety of clamping configurations. The versatile clamp may be easily made, without the use of any tools, to clamp onto thick and thin materials, alike, and to perform in applications which require an offset clamping operation. The versatile clamp may also feature one or more interchangeable clamping arm extensions and legs.Type: GrantFiled: September 20, 2007Date of Patent: September 20, 2011Inventors: Herbert L.

Patent number: 5791551Abstract: 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).Type: GrantFiled: July 24, 1996Date of Patent: August 11, 1998Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Jerry M.
