Title: Thermal safety device for automatically blocking pipes
Inventor: SCHULZE KLAUS
IPC: F16K17/38
Filed: 1997-02-24
Abstract: Thermal safety device for automatically blocking pipes.        A thermal safety device should be developed which, in the area of the closing element, has an uninterrupted circular cross section. Furthermore, the axial guiding of the closing element during the closing stroke should be ensured. In the axial continuation of a seat located within the casing there is a guide pin. A closing spring is aligned on this guide pin, and, when taut, the spring is situated as far as possible inside a blind hole, with a throat acting as a control edge, inside the closing element. Under the influence of the closing spring the ram, as part of a detecting element, when the safety device is in the open position, keeps the control edge adjacent to a click-stop edge.      Once the thermal solder melts away, however, the resulting change in position of the ram means that the control edge is no longer adjacent to the click-stop edge, so that the closing element, under the influence of the closing spring, takes up the closed position.      The thermal safety device acts to shut off pipes, especially gas pipes, automatically should an inadmissible rise in temperature occur.

Abstract: In the treatment of distal radial fractures. the involvement of the articular surface of the radius may in some case cause serious problems. Because the anatomic reduction of seriously damaged and displaced fragments of the articular surface can not be always reconstructed. As a result of that, in follow-up, the patient can have progressive degenerative changes all over the wrist joint including articular surfaces of the carpal bones which might have been undamaged after the original trauma. At this point, the treatment alternatives are the fusion of the joint and total replacement arthroplastic. Unfortunately, the current status of the total wrist replacement arthroplastic is not so successful as some other joints. Consequently, total wrist arthroplastic is a kind of option which surgeons usually try to avoid. Here a new conceptual approach to wrist replacement arthroplastics has been brought to the agenda which permits the surgeon the partial and/or hermipartial joint replacement. In case of necessity, this partial arthroplastic can be converted to total joint replacement, and can be used in tumors, traumatic degenerative and rheumatismal conditions of this joint.
