Abstract: A tap changer for uninterrupted switching between winding taps of a tapped transformer has first and second load branches for each phase to be switched. Each load branch has a main vacuum switch and in parallel thereto a series connection of a switch-over resistance and a respective auxiliary vacuum switch. First and second vacuum switching tubes each contain the main vacuum switch of the respective first and second load branches and the auxiliary vacuum switch of the other of the load branches.

Abstract: The invention relates to a tap changer having vacuum interrupters for switching over between winding taps of a tapped transformer without interruption. The tap changer according to the invention having vacuum interrupters is based on the general idea of combining the functionalities of at least one conventional vacuum switching contact which switches under load and a further mechanical switching means according to the prior art in just one single vacuum interrupter with two separately moving contact systems.

Abstract: The invention relates to a tap changer for the interruption-free switchover between winding taps of a tap-changing transformer. Furthermore, the present invention relates to a novel vacuum interrupter which is particularly suitable for such a tap changer. The tap changer according to the invention is based on the general concept of combining in each case one main contact (V1) and one mechanical switching means (U1), connected in series therewith, of a first load branch and an additional resistive contact (V3) of a second load branch in only a single vacuum interrupter (1) with a common housing (5).

Abstract: A method for manufacturing a stripline laser which is composed of a plurality of constituent parts assembled together with at least two of the parts being soldered to one another, characterized by the step of soldering being by a soft solder, subsequently cleaning the interior of the assembled laser by subjecting it to the influence of a plasma treatment, continuing the plasma treatment to passivate the interior surfaces of the assembled parts of the laser, and limiting the temperature of the parts joined together by the soft solder to, at most, 150.degree. during each of the plasma treatments. The method is particularly suitable for utilization to form a CO.sub.2 stripline laser, and includes adding a CO.sub.2 gas during the second or continued plasma treatment for passivating the surfaces by saturating them with CO.sub.2.

Abstract: The invention relates to an electrical overhead cable rope comprising an integrated optical communication lead (13), in which metallic wire elements (14, 15, 16) surround a tube (1) or noble steel, in which at least one optical waveguide (2) is contained. Corrosion of the wire elements of the overhead cable rope is prevented by providing a tube (1) of noble steel having applied to it a water-tight coating which establishes a continuous electrically conducting connection between the tube of noble steel and the wire elements (14, 15, 16) surrounding it.

Abstract: The invention relates to a roll manufactured with a light waveguide conductor (LWG-conductor), in particular for the transmission of optical signals from and to, respectively, a moving body. A perfect winding construction from which the conductor can be unreeled without interference is obtained in that the LWG-conductor (1) is wound to form a self-supporting cross-roll without a winding core.
