    摘要: The PC-boards are contained in sealed enclosures, and serially effective heat pipe systems conduct thermal energy from the respective sources of development (e.g., power transmitters) to the top and from there to a heat pump system. Stacking such units and operating the heat transfer partially in parallel is disclosed.

    摘要: A cable splice, tube joint, or the like, is covered by a fitting constructed as a split hose provided along one edge with a rail made of metal or a strong synthetic; a similar rail element or an integral fastening element is provided on the other edge and secured to the first rail by welding, adhesive bonding, or soldering in order to obtain a joint which resists tension and compression. The hose has been laterally slipped onto and over the cable splice or tube joint and, after the split joint has been sealed (or concurrently therewith), the hose is heat-shrunk. Various rail configurations are shown; a method of making the hose is explained.

    摘要: A system is disclosed, which operates with active units for the line-conducted, digital transmission of communications between the exchange of a telecommunication network and subscribers connected thereto. At least one cross connector, operating with active electrical components, is connected to the exchange by a line containing at least one optical and/or electric transmission element. At least two distribution terminals, operating with active electrical components, are connected to the cross connector by a line containing at least one optical and/or electric transmission element. At least one subscriber is connected by an electrical line to the distribution terminals, which are always installed near a subscriber.
