    Abstract: A fuse cutout assembly (21) including a containment housing (22), a fuse (23), amounting assembly (24) mounting the fuse (23) in the housing (22) for electrical connection to an electrical circuit. A plunger assembly (29) is movably mounted at least partially inside the housing (22) and preferably surrounding the fuse (23). An electrical conductor (28) is electrically connected to the fuse (23) and mechanically connected to the plunger assembly (29). The plunger assembly (29) is supported in the housing (22) in a first position and is formed to be propelled inside the housing (22) away from the first position to a second position by the hot gases generated upon rapid melting of the fuse (23). Movement of the plunger assembly (29) is preferably yieldably resisted by the air trapped between the plunger assembly (29) and the housing (22), which may be vented during plunger movement. Additional venting (94) for excessive pressure buildup can be provided in the housing (22), and a method of containing the hot gases and metals generated during fuse melting and retaining the components of the cutout assembly (21) is also provided.

    Abstract: An orthopaedic and orthotic bi-pivotal hinge assembly having a hinge body and a pair of coplanar and independently-pivotal hinge arms. The proximal end portions of the hinge arms are disposed within the hinge body and have planar abutment surfaces that face in the same direction and are disposed immediately adjacent each other when the arms are in full extension. Continuously variable extension control is achieved by an adjuster screw carried by the hinge body that is engageable with both of said planar abutment surfaces of said arms.
