A reusable connecting device is disclosed which utilizes a heat-recoverable metallic driver connected to a socket having a biasing portion and a sequentially-operating overload portion. When it is desired to make a connection between this device and other objects, the object is placed within the socket and the driver is caused to shrink, thereby overcoming the biasing portion of the socket and causing the socket to contact and hold the object, the overload portion then acting as an overload mechanism for the heat-recoverable metallic driver. |

A device for forming a mechanical and/or electrical connection between a plurality of elongate objects 1, 2, for example bus bars in electrical switchgear, comprises one or more inserts or shell members 9, 10 that can be positioned about the ends of the objects to form a tubular assembly extending between the objects. One or more memory metal drivers in the form of bands or rings 7, 8 may be provided for retaining the tubular assembly in position and forcing the shell portions against the objects 1, 2 so that a good electrical contact is formed. Preferably an annular protuberance or contact surface 12 is provided on the internal surface of the shell members 9, 10 at each end thereof, and are preferably arranged so as to be partly flattened as the bonds or rings 7, 8 contract, thereby increasing the contact area between the shell members and the objects 1, 2. |

A reusable connecting device is disclosed which utilizes a heat recoverable metallic band disposed about a resilient member such as the tines of a forked member. Where the resilient member is a forked member, the forked member has at least two tines which are spaced from one another and which are elastically mounted so that they can be moved inwardly but, when so moved, exert an outward force. When it is desired to make a connection between this device and other objects, the object is placed between adjacent tines and the metallic band is caused to shrink thereby forcing the tines towards one another and causing them to contact and hold the object between them. The device is reusable in that when the temperature of the metallic band is lowered to cause the metal to transform to a martensitic state, it may be easily deformed due to a decrease in yield strength. The elastic nature of the tines or other resilient member causes them to push against the band resulting in a deformation of the band. This deformation permits the tines to move away from one another and releases the object held therebetween. However, once the metallic band is heated to a temperature at which the band reverts to its austenitic state, the band again contracts and moves the tines toward one another permitting a strong electrical or physical connection to be made. |

Described herein is a reusable connector which may, for example, find use in making electrical connections. The connector comprises a heat recoverable metallic band disposed about a non-resilient, deformable member, typically a hollow cylinder that has been slotted to form tines, that has been deformed from an original configuration. When it is desired to make a connection, an object member is inserted into the deformable member and the metallic band is caused to shrink and drive the deformable member towards its original configuration thereby engaging the object member. Preferably the object member has an enlarged portion that is positioned so that when the object member is inserted, the enlarged portion passes through the metallic band. Recovery of the metallic band behind the enlarged portion inhibits withdrawal of the object member from the connector. The connector is reusable in that when the temperature of the band is reduced to cause it to revert to its martensitic state, the object member can be removed from the connector. If the object member has an enlarged portion, it will re-expand the deformable member and the recoverable member during withdrawal. |

The disclosure relates to high gain electrical relays which are operable at very low power levels and which, when arranged in a relay system with impedance matching to an energizing power source, are operable at the low power levels used in energizing integrated circuits. The relays utilize nickel-titanium alloy wires which are conditioned and arranged to display sharp, reversible changes in shape and modulus of elasticity as the wires are heated and cooled through a temperature transition range, the alloy wires being disposed, preferably with impedance matching means between the wires and energizing power sources, to be heated through the noted transition temperature range by directing current from such low power sources through the wires, thereby to initiate relay operation. The relay construction provides unusually high gain so that relay operation from such low power sources is effective for regulating operation of various types of components used in electrical apparatus. |

Method and apparatus is provided in which a deformable inner member is positioned inside a hollow outer member. The inner member receives a force which causes its outward deformation towards an inner surface of the outer member. An object such as one or more electrical conductors is placed between the inner and outer member to achieve a mechanical and/or electrical connection. If an electrical connection is desired, the inner and/or outer member is chosen to be electrically conductive, and the deformation of the inner member towards the outer member also displaces the insulation from the electrical conductors thereby exposing bared portions of the conductors and realizing an electrical connection.
