Abstract: The fuseholder includes a current limiting fuse mounted within a fuse body and a lower contact and hinge assembly. The fuse body has contact assemblies mounted on each end thereof. The lower contact assembly on the fuse body is mounted on a hinge which is rotatably supported on an interchangeable cutout mounting. The current limiting fuse includes a fuse element spirally wound around a spider which extends the length of the fuse body. The fuse element includes a high current fusible element and a low current fuse element. The fusible element includes a plurality of spaced reduced areas and is supported on the spider by support surfaces which are located between adjacent reduced areas of the fusible element. An auxiliary wire also extends the length of the fuse body about the spider. The hinge includes a hinge member rotatably mounted on the interchangeable cutout mounting, a connective member supporting the contact assemblies and fuse body with current limiting fuse, and a latch for latching the hinge member to the connective member in a contracted position. The latch is connected to a trigger wire attached to the lower end of the auxiliary wire to maintain the hinge and connective members in their contracted position. Upon the melting of the trigger wire due to a current overload, the trigger wire releases the latch thereby allowing the connective member to move to an extended position with respect to the hinge member such that the current limiting fuse drops out of the interchangeable cutout mounting.

Abstract: A terrain light fixture has a hollow body that is normally sunk within the ground, and a movable member disposed to telescope between a position retracted within the body and substantially flush with the ground surface and a position extended above the ground surface. The moveable member carries a light source, typically a 12 v.d.c. high intensity light bulb, that is energized in the extended position of the moveable member. The motive force to move the member is provided by an electrical lift mechanism, preferably either an electric motor or a shape-memory alloy. The motor-based lift mechanism operates equivalently to the power antenna of an automobile. The shape-memory alloy is typically configured as a spring. The application of electrical energization to both the light source and to the lift mechanism is preferably enabled by a switch that is responsive to sensed ambient light conditions. The energizing power may be external, or may be provided by an internal battery which is rechargeable from a solar array.

Abstract: A catheter or the like is steerable through cavities within a body and aimable toward organ or tissue within the body. The catheter includes an elongated tubular member having a distal end for insertion into the body and a temperature-activated memory element in the distal end of the hollow tubular member. The memory element has an initial shape and moves to assume a predetermined shape when heated to a predetermined temperature. A control system is provided for selectively heating the memory element to the predetermined temperature so that the memory element is moved in a first direction to deflect the distal end of the tubular member and thereby steer or aim the catheter within the body. A spring assembly is provided for yieldably urging the memory element in an opposite second direction to establish the initial shape and also to aid in returning the memory element to its initial shape when the temperature of the memory element is less than the predetermined temperature. The spring assembly includes a core member for supporting the memory element and a resilient member. Both the core member and resilient member are preformed to assume curved shapes and both move to assume a shape other than the preformed curved shapes in response to movements of the memory element in the first direction.

Abstract: A heat exchanger which includes a turbulence promoter interposed between inlet and outlet ports of the heat exchanger and spring means made of a memory alloy for moving the turbulence promoter in a predetermined direction. The area of the heat transfer surface in which the heat transfer coefficient or the unit thermal conductance is increased by the turbulence promoter is changed in accordance with movement of the turbulence promoter. As a result, the heat exchanger effectiveness or temperature effectiveness is intentionally changed and the temperature at the outlet port of the heat exchanger is maintained within a certain range of temperature.

Abstract: The invention generally relates to polymer nanocomposite films that possess shape memory properties at elevated temperatures. Such films can absorb microwaves, are thermally conductive, are electrically conductive and have increased mechanical strength. In addition, the present invention relates to methods of fabricating such films into 3D objects. Due to the improved properties of such films more advanced sensors and microwave shields can be constructed.

Abstract: An adaptable mold includes a thermoform material that is able to manufacture different articles. The thermoform material may be brought to a transition temperature at which it may be formed into a first mold cavity for a first article. After using the thermoform material to mold the first article, the thermoform material may then be formed into a second mold cavity for a second article. The thermoform material may be a shape memory polymer able to return to a learned shape to aid in forming to a new mold cavity. The adaptable mold may use a fill material to provide compressive support to the thermoform material while molding.

Abstract: Shape memory tissue engagement elements (15) are created using shape memory alloys or shape memory (SM) composite sheets (33, 36) with one or more SM material sheets (20, 32). Arrays of the tissue engagement elements may then be inserted or molded into flexible base materials forming pads for tissue engagement. In certain embodiments, the composite sheets incorporate two SM material layers (20, 32) having differing transition temperatures to allow activation of one layer for tissue engagement and activation of the second layer for tissue release. In exemplary embodiments, insertion of interconnected tissue engagement elements (46) into a base layer (19) with slots (48) provides a completed pad array. In alternative exemplary embodiments, vacuum forming of composite sheets (51) with cutting of corrugated sides (53) to form tissue engagement elements allow production of complete arrays of tissue engagement elements. Overmolding the arrays with a flexible base material (19) provides a completed pad.
