A simple and cost-effective method is provided, according to which a positive temperature component (PTC) element directly controls the element made of a shape memory alloy. A simple and cost effective device for performing the method has a PTC element series-connected upstream from the element made of a shape memory alloy, in the electric circuit for the element made of a shape memory alloy.

摘要:
A method for producing a high-Tc superconductor having a strip shape and having at least one superconductive conductor core by forming a conductor initial product and annealing. The forming is in this case intended to include at least two flattening steps. A flattening step which follows a preceding flattening step is intended to result in the percentage thickness reduction in the cross section of the at least one conductor core being greater than that from the preceding flattening step. The strip conductor produced in this way advantageously has a plurality of conductor cores that are embedded in a Ag material and are composed of a bi-cuprate.

A disconnect switch for the load circuit of a vehicle battery, includes a movable contact element (81) and a stationary contact element (64) that are linked with a locking mechanism. For releasing the locking mechanism a shape-memory alloy release element (4) is used that contracts when heated. For closing the locking mechanism a shape-memory alloy spring element (110) is provided that induces closure of the mechanism by expansion.

A switching device includes a strip-shaped actuator element including a shape memory alloy, which is connected to a movable contact part of a switching contact. It is intended that an at least largely extended shape has been impressed into the actuator element at an annealing temperature. It is intended that, in the operating state in which the switching function is not triggered, the element rests on a deflecting element with frictional engagement in such a way that the deflecting element exerts, on the concave inner side of the actuator element, a counterforce partially counteracting the curving of the latter in this state.

A process is disclosed for producing a strip-shaped superconductor with several conductor cores made of a high-Tc superconducting material and surrounded by a normal conducting material. A conductor blank (2a) produced from a fabricated conductor should be rolled flat at least once. For that purpose, the conductor blank is fed into the gap (7) between two rollers (8, 9) of which the rolling surfaces (8a, 9a) describe a concave, at least approximately elliptical contour at least in the rolling region (8a). The strip-shaped multi-core conductor produced in this way advantageously contains superconducting cores made of a bi-cuprate embedded in an Ag matrix.

The assembly element is mechanically connected to two component parts of a device (2) at least once the device is assembled. A shape-memory metal element (6i, 7i), is provided as the assembly element, the metal element having a first form during assembly of the device (2) and a second form, which assures the mechanical connection between the two component parts (3a-3d, 4a-4c) of the device, when the device is assembled. The second form is memorized by the shape-memory metal element before assembly, by its shape-memory properties.
