Abstract: An interior storm window comprising an adjustable seal extending about the perimeter of the storm window and being in the form of a strip of extruded, flexible plastic material having an inverted "U" shape with a sealing bead extending upwardly from the bight of the "U" and spaced arrow-shaped portions extending downwardly from each side of the bead. The end portions extend into correspondingly shaped openings in an extruded frame of rigid plastic material which surrounds a pair of glazing sheets whose outer perimeters extend into and are firmly supported by the frame.

Abstract: A safety release closure suitable for use in a mass transit vehicle which can be rapidly and efficiently removed either inwardly or outwardly in case of an emergency. The closure includes a removable sash that is mounted within a frame opening and secured in place by means of inside and outside deformable seals disposed between the frame and the inside and outside margins of the sash. The perimeter walls of the opening that face the sash are contoured so that the opening is wider across both edges than it is along the middepth region whereby the sash can be easily removed in both directions without it becoming wedged or otherwise jammed in the frame. Means for stripping the seals on both sides of the sash are provided for as are handle means which enable a person to pull the sash out of the frame after the seal has been removed.

Abstract: Method and apparatus for relieving an elevated pressure behind a wall. The apparatus includes a rigid frame mountable over an orifice in the wall and a rigid panel sized to fit within the opening in the frame and to cover the orifice. The panel is mounted in the frame by a hinge which permits the panel to pivot with respect to the frame. The panel is also releasably secured to the frame so that when an elevated pressure is not present, the panel and frame are secured against fluid leakage. If an elevated pressure is developed behind the wall, the panel pivots with respect to the frame and thereby releases the elevated pressure.

Abstract: A sealing device comprising a door or gasket of rigid material curved in one direction and straight in another, as in the form of a portion of a cylinder, and having convex and concave surfaces. Either or both such surfaces has a circumferentially continuous groove across the straight and curved portions that contains a molded in place packing of resilient material. The packing has a portion projecting from the groove and has a recess extending into the groove. The sides of the recess are either parallel to a transverse axis whose direction corresponds to the direction of travel of the mold members relative to each other when separating so that there are no undercuts in the packing material into which portions of the mold would project and prevent separation of the mold members after the molding operation without damaging the packing.

Abstract: A device for sealing a steel door of a coke oven, the structure provides a sealing member disposed over the entire periphery of the steel door, said member closing the opening formed in the wall of the body of the coke oven. The sealing member includes a deformable covering material and a spring disposed within said covering material, the combination forming an elastic member, the deformable covering material being biased by the spring against the surface of the body of the coke oven about the periphery of the opening closed by the steel door, the sealing member being carried on the door. The invention further provides a deformable tar-receiving cover which prevents accumulation of tar between the door and the sealing member.

Abstract: A flexible insulating blanket attached to a metal backing with adjustable panels about the backing is used to cover the opening of a carbon anode baking furnace to bring about sealing contact between the cover and the furnace walls so as to minimize thermal requirements and losses from the furnace.

Abstract: A burial vault formed from concrete which includes a hollow chamber having an open end closed by an end plate connected to said chamber by a plurality of bolts. An annular resilient seal is interposed between said end plate and the adjacent chamber end. Said seal is fixedly connected to said end plate and is bindingly retained between said end plate and chamber by said bolts connecting said end plate to said chamber.

Abstract: The fabric end wall of a camper is fastened to the outer side of a frame member by a fastener detachable from inside the camper, to provide an escape opening in an emergency. The fastener comprises a pair of slotted tubular fastener elements on the outer side of the frame receiving a folded edge of the fabric wall and a flexible element in the fold and tubular elements to secure the edge of the fabric wall, the flexible element being accessible at its central portion for withdrawal to release the fabric wall.
