Abstract: An insulated door for refrigerators, freezers or similar cabinets where the inner and outer door surfaces are normally subjected to substantially different temperatures. The main door components, the door face and drum, are interconnected without the use of threaded fasteners such as screws or bolts. Instead a hardened, foamed in situ insulating material forms the main interconnection between the door face and drum, securing them together but yet accommodating thermally induced, relative movement between the two components. In constructing the door S-shaped retainers are used which receive in their oppositely opening loops the edges of the face and drum. Temporary spacers are then interposed between the face and drum edges for the foaming operation.

Abstract: An improved breaker strip for a domestic refrigerating appliance which may be fitted in place prior to the appliance being insulated by an in situ foaming process to prevent foam leakage. First and second mechanical sealing means of a conventional type are provided to seal along the edges of the breaker strip to the appliance walls. An additional flange seal is further provided for each of the first and second sealing means so as to enshroud each means and form a small chamber therebetween and the respective flange seal. Reactive liquid which leaks into the chambers tends to expand to block them prior to any escape of such liquid past the conventional seals, and also to bias the conventional seals into greater sealing contact with the appliance walls.

Abstract: In a domestic two door side by side refrigerator, means for adjusting the curvature of the mullion cover so as to provide thereon a good sealing surface of the doors. The means comprises a spring which biases the mullion cover in a first direction, and a screw element acting upon the mullion cover in opposition to the spring bias.

Abstract: A one piece extruded elastomeric support and retention liner gasket for resiliently and sealingly mounting a plastic sheet food liner to the cabinet in a refrigerator or freezer includes a barbed lower body which is pressed into an upwardly opening J-shaped channel formed adjacent the inner rim of the cabinet, the gasket including an intermediate inwardly projecting arm and a spaced resiliently supported upper head section defining with the arm an inwardly opening peripheral groove for receiving the outer peripheral flange of the food liner, the arrangement being such that as the gasket is pressed into the J-channel the arm engages the short leg of the J-channel so as to be upwardly deflected thereby narrowing the slot and the head section engages the long leg of the J-channel so as to downwardly deflect thereby also narrowing the slot whereby the flange is resiliently compressively gripped in assembly therebetween.

Abstract: A nuclear accident carrier for conveying an injured contaminated person comprising a portable base into which a stretcher supporting the person can be inserted, and a lid for isolating the person in the base from the outside. The lid is made from a transparent material and is provided along an edge with a sealing strip that, when the carrier is closed, is clamped between the edges of the lid and the base.

Abstract: A shelf assembly particularly adapted for use in a household refrigerator comprises a cantilever supported frame and a sliding shelf which may easily be removed from the frame. The frame includes a pair of shelf guides or tracks which, in a preferred embodiment of the invention, are inwardly extending horizontal flanges attached to frame side members. The shelf includes a pair of shelf side members which are slidably supported on the cooperating upper surfaces of the horizontal flanges. Attached near the rear corners of the shelf are outwardly extending projections which ride against the lower surfaces of the flanges to prevent the rear of the shelf from moving upwardly. A stop prevents the shelf from being pulled out farther than the extended position.

Abstract: A gasket assembly for side-by-side doors of a household refrigerator-freezer has first and second cooperating gasket elements. Each gasket element is connected to a respective door of the refrigerator-freezer. Each gasket element has a magnet in a magnet chamber for sealing the doors one to the other and a longitudinally extending insulating chamber for contacting the refrigerator mullion and forming a seal between the respective door and the mullion, as is known in the art.The improved construction of this invention has a pair of elongated flanges, each connected to a respective insulating chamber. The flanges each extend from their respective gasket element toward the other gasket element in the closed position of the doors. Where a mullion is present, the flanges are each urged into contact with the mullion by their associated magnet for forming an improved seal. In the absence of a mullion, the flanges contact one another for sealing one gasket element to the other.
