Abstract
Frames for mounting windows within the walls of enclosures for isolating or sealing substances such as radioactive or other hazardous substances from the surrounding environment. In a first embodiment of the present invention, a window assembly includes a two-piece frame that is welded into the wall of an enclosure. In a second embodiment of the present invention, a window assembly includes a three-piece frame that is clamped to the wall of an enclosure. The frame assemblies may also be used to mount structures other than windows to enclosure walls, such as ducts or pipes intended for passing power, gas, vacuum, or other utilities into the interior of an enclosure.
Claims8
A system comprising:
- an enclosure having a non-glass wall, the non-glass wall having an interior surface facing the inside of the enclosure and an exterior surface located on the outside of the enclosure, and having a plurality of aperture surfaces extending from the interior surface to the exterior surface of the non-glass wall and defining an aperture through the non-glass wall;
- a first frame member affixed to the plurality of aperture surfaces, the first frame member having a ledge surrounding the aperture, a raised portion extending perpendicular to and surrounding the ledge, and extending over at least a portion of the exterior surface of the non-glass wall;
- a lip formed in the first frame member around an outer edge of the raised portion, the lip having a first surface abutting an exterior surface of the non-glass wall and a second surface lying within an inside periphery of the aperture passing through the non-glass wall;
- a plurality of threaded holes formed in a mounting surface on the raised portion of the first frame member;
- a second frame member located outwardly from the exterior surface of the non-glass wall and having a clamping surface surrounding the aperture, wherein the clamping surface of the second frame member lies substantially parallel to the ledge of the first frame member;
- and
- a plurality of holes extending through the second frame member, wherein the plurality of holes is spaced for alignment with the plurality of threaded holes in the first frame member and the second frame member is fastened to the mounting surface of the first frame member with a plurality of threaded fasteners.
