  • Patent number: 11561358
    Abstract: A method for the continuous production of a thin-walled, perforated metal hollow profile with one or more fibre waveguides mounted therein. The method includes supplying of a flat metal strip at a first supply rate to a deforming device, which continuously deforms the metal strip into a metal hollow profile with a slot running in a longitudinal direction. Two opposite edges of the metal strip deformed into the metal hollow profile that lie flush against one another in a contact region extending in the longitudinal direction of the metal hollow profile are continuously welded to one another, drawn off from the welding region and perforated.

  • Patent number: 11555843
    Abstract: A method for localizing a short circuit between a conductor and an electrically conductive shield of a high-voltage cable comprises providing at least two measuring apparatuses arranged at the high-voltage cable at a known distance from one another and having timers, synchronized with one another, and a measuring device for detecting an electric current flowing in the shield and/or an earthing line connecting the shield and earth. The measuring apparatus transmits pairs of current measurement values and associated values of the timer to an analysis unit, which, upon the occurrence of a current exceeding a threshold value and/or of a current profile over time that satisfies specific stipulations, feeds to a calculation unit the associated values of the timers and also an indication about the location of the measurement, for which first effects of the short circuit occurred.

  • Patent number: 11548095
    Abstract: A process for the continuous production of thin-walled, radially closed hollow profiles which are composed of nonferrous metals and have a small cross section comprises supply of a flat strip of the nonferrous metal to a forming apparatus (212) at a first supply speed, where the thickness of the strip corresponds to the wall thickness of the hollow profile. The forming apparatus (212) is configured for continuous forming of the flat strip supplied into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region. A welding apparatus (216) continuously welds the edges which rest flush against one another by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats a point in a welding region which has a diameter which is less than 20% of the cross-sectional dimension of the hollow profile.

  • Patent number: 11525538
    Abstract: A plug-in coupling for connecting a first double-walled vacuum-insulated cryogenic line to a second. The plug-in coupling has a coupling plug and a coupling socket. The coupling plug can be plugged into the coupling socket, these being retained in a plugged-together state by fixing means. A guide column is arranged on the coupling plug or the coupling socket. The guide column has arranged on it elastic means which, in the assembled state of the plug-in coupling, are subjected to stressing and which subject the coupling plug and/or coupling socket to an elastic force which strives to release the coupling plug and coupling socket from one another as soon as the fixing means no longer hold the coupling plug and coupling socket together. The elastic energy stored in the elastic means ensures that, in the event of an emergency, the coupling plug and coupling socket are quickly released from one another.
