    摘要: A circuit protection device includes a housing, which includes first and second electrodes. The device includes a conductive slider inside the housing. At a first location within the housing, the slider provides an electrical connection between the first and second electrodes. At a second location within the housing, the slider does not provide the electrical connection. A spring is secured to and stretched between the slider and an inner side of the housing such that the spring is held in tension in an expanded state. The slider is held at the first location by a solder between the slider and the first and second electrodes. After the device is armed, detection of an over-temperature condition causes the solder to begin to melt and the spring to compress and pull the slider to the second location within the housing, thus severing the electrical connection between the first and second electrodes.

    摘要: A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state.

    摘要: A reflowable thermal fuse includes a positive-temperature-coefficient (PTC) device that defines a first end and a second end, a conduction element that defines a first end and a second end in electrical communication with the second end of the PTC device, and a restraining element that defines a first end in electrical communication with the first end of the PTC device and a second end, in electrical communication with a second end of the conduction element. The restraining element is adapted to prevent the conduction element from coming out of electrical communication with the PTC device in an installation state of the thermal fuse. During a fault condition, heat applied to the thermal fuse diverts current flowing between the first end of the PTC device and the second end of the conduction element to the restraining element, causing the restraining element to release the conduction element and activate the fuse.

    摘要: A processing technique and a composition which allow compositions of PBT polymers or copolymers to be formed into blow molded articles, especially medical balloons such as dilatation or stent placement balloons, from extruded tubular parisons. The process includes a longitudinal stretch step run at a temperature below the Tg of the polymeric material and a radial expansion step run at a temperature above the Tg of the polymeric material. During the longitudinal stretch step, the tubing is subjected to high internal pressure. In the composition a small amount of boric acid is added to the polybutylene terephthalate in a melt blend to give a formulation which has reduced crystallinity after extrusion and which can more readily fashioned into high strength blow molded articles than PBT by itself. Articles, which may be formed using the invention include medical device balloon articles in which the polymer consists essentially of PBT optionally blended with boric acid.
