Abstract: An insulated glass window assembly including a cordless integral shade with level correction, a sliding follower, and an air permeable spacer assembly. Cords are eliminated by confining the window covering movement to one dimension. Level correction is achieved by pivotally connecting the shade bar to the supporting operator or shade support, so that the bar can be re-leveled by raising or lowering the bar against the IG spacer. The follower slides in a track on one side of the IG. The spacer includes an air passageway between the desiccant chamber and the space between IG space, and the hole is covered by an air-permeable patch to prevent unwanted leakage of desiccant into the viewable area.

Abstract: A retractable screen door for drawing a flexible screen panel across an opening, including a flexible screen wound around a spring biased take-up shaft, and guide rails for guiding the screen as it is moved across the opening. A unique latch mechanism is disclosed, said latch mechanism being located in the guide rails. Further, the screen may include an adjustable gear assembly for changing the tension on the spring. The retractable screen is optionally designed to have the appearance of a common door casing.

Abstract: A penetration resistant doorlight including a frame and a laminated window assembly. The window assembly includes a glass panel laminated to a security film such as P.E.T. The security film extends beyond the perimeter edge of the window assembly to overlap the door. The film is secured both to the frame and to the door. In the preferred embodiment, a reinforcing insert is included in the frame and overlaps all of the window, the door, and the film.
