Abstract

1450962 Releasable fastenings BUNKER RAMO CORP 31 Oct 1973 [28 Nov 1972] 50643/73 Heading E2A [Also in Division H2] A two-part coupling comprises a heat-activatable locking member 25 disposed in a cavity 46 formed between the coupling parts when they are coupled, the locking member changing shape in response to the application of a predetermined amount of heat to bear against the cavity surfaces and rigidly lock the parts together. The locking member 25 is a ring of a memory alloy of nickel and titanium of a shape which changes from that shown in Figure 1 to that in Figure 5 when heated, retaining the changed shape when allowed to cool. The coupling parts 12, 14 are held together by a screw ring 16 rotatably mounted by a washer 36 on the part 14, and include an O-ring 31 and one or more contacts 26, 28 mounted in insulating bodies 22, 24 within shells 18, 20, opposed annular surfaces 42, 44 of the shells forming the cavity 46. The ring 25 has serrations (25a, Fig. 2) for engaging the cavity surfaces and tabs 25b to provide visual indication of the shape of the ring. Application of cooling causes a return of the ring shape to that in Figure 1. A further embodiment (Figs. 6-10, not shown) comprises a bayonet action coupling with the locking member having the general form of a wave washer.
