Abstract: Disclosed is a window assembly for use in mass transit vehicles which allows the quick and easy removal and replacement of transparent sacrificial glazing panels which protect the glazing of the window from vandalism and wear. The window assembly utilizes a sacrificial protective panel and mounting arrangement which allows quick and easy replacement of protective panels on one or both sides of the window assembly, but inhibits removal by non-maintenance personnel such as vandals. The frame of the window assembly incorporates one or more retainers which fit into slots along the interior sides of the window frame and sandwich the glazing between the frame and the retainers. In turn, the retainers are essentially “locked” into position in the frame by an inner protective panel, which significantly inhibits the removal of the retainers from the window assembly when the protective panel is in its desired position against the windowpane.

Abstract: A structural panel for building structures such as residential houses or the like comprises a honeycomb or other cellular core sandwiched between two metal face sheets and surrounded by a metal frame. Frame members of the frame form mechanical interlocking connections with the face sheets of the panel. Side frame members of the panel define interlocking protrusions and channels for making interlocking joints between panels. A building structure employing the panels for forming floor and roofs includes brackets that extend into a gap between the side frame members of the panel at the panel joints and attach to the side frame members. The brackets are used for attaching the panels to other parts of the structure.

Abstract: The PowerBrace system gives a positive solution to basement wall problems. When the wall cracks and bulges are due to freeze or hydrostatic preasure, PowerBrace can hold it from further movement and in most cases straighten it. By tightening the top bracket the PowerBrace system puts preasure on the top of the beam and straightens the wall. This movement is usually gradual as the system is retightened. Unlike many other wall repair systems the PowerBrace system does not rely on questionable soils outside the wall to hold the wall, nor does it put to much stress on the beam. Any bending of the main beam constitutes a failure in the system. By anchoring to the concrete basement floor and to the solid floor joist system, the PowerBrace system is solid and will not be aloud to shift or fail. the PowerBrace system solves problems relating to the sheering effect at the base of the wall caused by hydrostatic preasure, as well as any other wall movement.
