  • Arrangement for electrically conductively connecting two superconductive conductors
    Patent number: 9177698
    Abstract: An arrangement for electrically conductively connecting two superconductive strip-shaped electrical conductors (1, 2) having at least approximately the same width, where the two conductors (1, 2) rest against each other with their end faces against each other in a connecting point (V). A strip (6) of superconductive material is soldered to the two conductors (1, 2), where the strip extends beyond both conductors so as to cover the connecting point (V). A strip (6) is used which has, only in the area of the connecting point (V) between the two conductors (1, 2), at least approximately the same width as the conductors, and where the strip narrows on both sides of the connecting point (V) and facing away from the connecting point (V).

  • Method of producing metallic composite pipes
    Patent number: 9162322
    Abstract: A method is provided for producing a pipe from a band which has a layer of a first metal and a layer of a second metal, the layers being metallurgically bonded to one another over the entire length of the band. Along the two longitudinal edges of the band, the first metal is removed from the second metal in strips which run over the entire length of the band. The band is formed into the open-seam pipe with the first metal located on the outside, and the abutting edges of the layer of the second metal are welded to one another forming a pipe which is closed all the way round. In the region of the weld seam, a layer of the first metal is then deposited on the second metal to produce a pipe with a layer of the first metal which is closed all the way round.

  • Method of electrically conductively connecting two superconductive cables
    Patent number: 9159473
    Abstract: A method of electrically conductively connecting two superconductive cables includes freeing the conductors and screens of surrounding layers at the ends of the two cables. Subsequently, the ends of the two cables (1, 2) are placed next o each other and parallel to one another in such a way that their free ends point, in the same direction, and the ends are rigidly connected to one another in this position. The conductors and their screens are electrically conductively connected to each other through electrical contact elements (8, 9) extending transversely of the axial direction. and the two cable ends treated in this manner are arranged in a housing (10) of a cryostat when building up the transmission length which, during operation of the transmission length, a flowable cooling agent with insulating properties flows through the housing.
