Abstract: Disclosed is a deicing device for deicing cables. The deicing device includes one pair of conductive wires connected to and helically wound along the cable. The conductive wires are connected at one end to a pulsing device which generates an electromagnetic pulse within the wires, and are connected together at the other end. Upon a passage of the electromagnetic pulse in the wires, a repulsive force is created between the wires, which shakes the wires and shatters the ice that may be attached to the cable.

Abstract: A self-propelled member or carriage runs along a stationary surface-conducting cable formed of alternately disposed conducting and insulating turns. The carriage is provided with a rotor extending around the cable and having contacts in a conductive relation with the conducting turns of the cable. At least two pulleys are rotatably mounted to the carriage with the cable interposed between the pulleys. An electric motor is operatively electrically connected to the contacts of the rotors and is drivingly connected to the pulleys. Electric power is transmitted from the cable by the rotor to the motor whereupon the motor drives the pulleys to propel the carriage along the cable.

Abstract: A contact line for the transmission of data and/or energy for conveyors and obots, or the like, with a pickup that incorporates a wiper head that is connected to the conveyor. The contact line comprises an electrically conductive plastic. As a result, the transmission of data and/or energy is enhanced and made less costly.

Abstract: A composite joint system is disclosed in which a composite structure containing carbon fibers embedded in a copper matrix in any configuration, e.g. in one direction, in random directions, in mesh form, spirally or radially is joined to another structure through a brazing material such as solder, Al brazer or Ag brazer. A film of metal such as Ni, Cr, Mo, W, Ta, Ti, Zr, V, an alloy of one or some of such metals, or the combination of some thereof is interposed between the composite structure and the brazing material. The metal film has a good wettability to both the composite structure material and the brazing material.
