Abstract: In known cables, the cable core is surrounded by a metallic inner layer of a sheath, and the inner layer is enclosed by a corrugated metallic outer layer of the sheath. In these cables, a high resistance against corrosion and high temperatures at a good shielding of the electric conductors is not ensured.The new cable (1) including the inner sheath layer (19) which is made of at least one flexible copper band (11) and defined by an electromagnetic shielding with a shielding attenuation from 80 to 115 dB, with the shield attenuation in this range being dependent from the wall thickness of the inner layer and rising monotonously with increasing wall thickness, and the outer sheath layer (27) which is made of a steel band and increases the high temperature resistance of the cable 1, has the advantages of a good temperature resistance even at high ambient temperatures, like e.g. in case of fire, and a high resistance with regard to corrosion.

Abstract: An environmentally sealed enclosure for encapsulating an in-line splice between cable segments. Cable gripping apparatus in the housing limits movement of the cable relative to the housing to prevent separation of sealant from a cable when a cable is positioned to extend through the entrance into the housing. Walls of top and bottom shell segments are configured to be locked together for forming an enclosure containing encapsulant for protecting the splice.

Abstract: The present invention is a joint assembly for allowing relative rotational movement of a camera relative to a stationary base structure. The assembly has a first flexible member which allows the camera to pan the surrounding are and a second flexible member which allows the camera to tilt. Each flexible member has a first surface facing a first direction and second surface facing a second opposite direction. One end each flexible member is folded over onto itself so that a portion of the second surface faces the first direction. The flexible members are constructed in an essentially radial shape to define a radial path. When an end of a flexible member moves along the arcuate path the member rolls over itself. That is, the portion of the flexible member that is rolled over, has its second surface facing the first direction instead of the second direction.

Abstract: A tape lead wire includes a polymer resin film and conductor films. The conductor films are directly deposited on the surface of the polymer resin film without using any bonding layer. The total thickness of the tape lead wire can be made smaller than that of a conventional lead wire. The tape lead wire has a high flexibility, can be easily bent, can extremely reduce the bending spring rigidity and is suitable for a magnetic head having a reduced size and load, which is imposed by a head supporting device on the magnetic head, and lowered flying height and peripheral speed.

Abstract: A coaxial cable (10) is for use in a power distribution network (N). The cable connects a surge protective device (SPD) in parallel with feeder lines (W1, W2) of the network. The SPD senses voltage surges on the feeder lines and clamps the voltages to a level at which loads (LD) connected downstream of the SPD are protected from excessive voltage levels. An inner conductor (12) and an outer conductor (14) have a dielectric material (16) separating them. The inner conductor is a round conductor, and the outer conductor forms a hollow cylinder in which the inner conductor and insulation material fit. A ratio of the inner diameter (D) of the outer conductor to the diameter (d) of the inner conductor is approximately 1.05. Thus, the diameter of the inner conductor is relatively large compared with the inner diameter of the outer conductor. A relatively large diameter of the inner conductor serves to minimize the dc resistance of the cable. Also, the dielectric material has a permittivity in the range of 2.0-4.0.

A weft yarn is woven with the array of conductor wires and the synthetic yarns to form the body zone. The weft yarn weaves only with the synthetic yarns to form the cut zones which are arranged in spaced manner longitudinally of the cable. The conductor wires weave with the weft yarn in a two up two down twill weave to form the body zones.

The inventive cable has a jacket formed of nonhalogenated polyethylene and nonhalogenated ethylene vinyl acetate and provides a combination of desired mechanical characteristics, improved performance and manufacturing features while eliminating undesirable corrosive products released during a fire.

Abstract: A device (1) for forming an electrical connection at the end of a bundle of wires (2) comprises an electrically insulating, preferably heat-shrinkable, sleeve (3), a metallic connecting element (4) located within the sleeve, and a quantity of solder (8) for forming a permanent electrical connection between the conductors. The connecting element (4) has a tapering internal surface which has a screw thread so that a temporary electrical connection can be formed by screwing the bundle of wires into the connecting element. Preferably the connecting element is formed by winding a wire, e.g. hard tempered copper wire, into a frusto-conical form. Splices in wire bundles may be made by means of a device in which the connecting element has a pair of internally threaded portions into which different cable bundles can be screwed.

The core is preferably filled with lead shot to provide weight to insure stability during use and operation.

Abstract: An electrical overhead transmission conductor cable having a steel reinforcing core which exhibits improved characteristics and unexpected conductivity above about 64% IACS is manufactured of a steel core covered by at least one stranding layer which is formed of round or trapezoidal shaped wire strands subjected to annealing before heat treatment and drawn and stress-relieved/annealed after stranding is completed, to provide a finished cable which includes an aluminum conductive portion which is dead soft, or "O" temper. The steel core of the cable carries substantially the entire tension load of both the core and conductors when suspended between vertical towers. The overhead transmission cable may be formed of trapezoidal cross section conductors wires for improved vibration performance characteristics.

Abstract: An insulating cover for a wire joint has a body which defines a lumen particularly adapted for receiving a crimp sleeve type wire joint. Longitudinal or coaxial ribs adjacent to a closed end of the lumen define an inside diameter which engages a relatively smaller joint, and the ribs are sufficiently flexible and the body stretchable so that the cover can alternatively receive a larger joint. A flexible skirt depends from the body and an elastic strap extends from the skirt with a ring retainer on the strap so that the strap can be extended through the crotch of the joint and secured to the body.

Abstract: A communication cable includes a core comprising at least one transmission medium and a sheath system which is disposed about the core. Means are disposed within the cable for preventing the longitudinal migration of water through the cable core, said means including both a hydrophilic material and a hydrophobic material in cooperative communication with each other. Specifically, a hydrophilic, water-absorptive material is supported by a yarn which is helically wrapped about various sections of the communication core. In a copper cable, the water-absorptive yarn may be wrapped about individual twisted pair conductors or a unit consisting of a plurality of twisted pair conductors or the cable core itself. In addition to the helically-wrapped, water-absorptive yarn, the cable of the present invention includes a hydrophobic, water-blocking material interdisposed to fill all voids and interstices within the communication core.

Abstract: A woven shielded cable in which a plurality of conductor wires and a plurality of spacer cords are alternately arranged to extend longitudinally of the cable. A woven outer cover is formed from metalized warp and weft yarns, to encapsulate the conductor and spacer cords to form a shield therefor. A set of binder yarns weave with the weft yarns on opposite side of the conductor wires and spacer cords to positively lock the warp yarns, the spacer cords and the conductor wires in position relative to each other. The cable may be formed with a hinge arranged longitudinally along an intermediate point. In this instance the warp yarns are divided into two groups which weave on opposed sides of the hinge and on opposite surfaces of the opposite sides. The conductor wires are stacked and shielded from each other when the cable is folded along the hinge.
