    Abstract: A DOOR HINGE HAS TWO PORTIONS OR COMPONENTS, ONE AFFIXED TO THE DOOR FRAME AND THE OTHER TO THE DOOR WITH MEANS CONNECTED BETWEEN THE COMPONENTS FOR RESILIENTLY URGING THEM TOGETHER. IF FORCE IS APPLIED TO THE DOOR, FOR EXAMPLE, IF IT IS BANGED, HUNG ON, OR FORCED OPEN TOO FAR, THE TWO HINGE PORTIONS WILL YIELDABLY SEPARATE TO MINIMIZE DAMAGE TO THE DOOR, THE FRAME, THE HINGE, OR ALL THREE. THE HINGE ALSO IS DESIGNED TO URGE THE DOOR SHUT WHEN IT IS PARTLY OPEN AND FURTHER, TO URGE THE DOOR BEYOND THE CLOSED POSITION, WHEN CLOSED, SO THAT NO LATCH IS NEEDED FOR THE DOOR. THE NEW HINGE HAS OTHER ADVANTAGES OVER PREVIOUSLY KNOWN LATCHLESS DOOR HINGES IN THAT THE NEW HINGE IS SELF-ALIGNING, IMPARTS NO RESISTANCE AS THE DOOR IS BEING OPENED, AND CAN URGE THE DOOR TOWARD THE CLOSED POSITION WHEN OPENED AT A WIDER ANGLE THAN HERETOFORE.

    Abstract: A pre-assembled tubing coupling or fitting including a sleeve, a retaining ring, a resilient sealing ring disposed external to said retaining ring, and a cap or plug. The cap is disposed to limit axial movement of the sealing ring and the coupling is preassembled so that upon insertion of a conduit into the coupling, an interference fit is formed between the conduit and the retaining ring and a seal is formed between the sleeve and the conduit, without the necessity of further assembly or tightening of the cap.
