Abstract: An assembly contains a disconnecting device for a surge-arresting device. A first contact and a second contact of the disconnecting device are connected by a first path having a switching element which can be thermally tripped. A second path is disposed electrically in parallel with the first path. An impedance element is disposed in the second path. A spark gap is disposed in the first path.

Abstract: A fuse assembly is formed with a receiving chamber. The receiving chamber is used for receiving a surge arrester indicator. The receiving chamber is a fireproof chamber and the surge arrester indicator is arranged in the fireproof receiving chamber.

Abstract: A conductor assembly includes an electrical conductor, a surge arrester which has a longitudinal direction, an operating state in which the surge arrester is configured to limit an overvoltage occurring in the electrical conductor, and a test state in which the surge arrester is not configured to limit the overvoltage. An electrically insulating support is disposed between the surge arrester and the electrical conductor in the longitudinal direction. The support is supported by the electrical conductor, and the surge arrester is supported by the support.

Abstract: Compositions for implantation into the human and animal body as bone replacement contain inter alia calcium and phosphorus and consist in particular of mixtures of powders and admixing liquids. They are suitable for preparing calcium phosphate cement pastes which cure at room and/or body temperature. The reaction systems contain a powdery base mixture comprising CaKPO4, Ca2NaK(PO4)2 and Ca(H2PO4)2.H2O.
