  • Patent number: 5089666
    Abstract: A novel cable for computerized monitoring system comprises at least one outer jacket of plastic abrasion resistant material, one inner layer of fiber reinforcing material and another jacket of plastic abrasion resistant material. The end which is intended to be connected to the tool has a clamp to hold the fiber reinforcing material in place and prevent the fiber reinforcing material from being damaged. The clamp is a hollow cylinder about 1 inch in length with a flange, is internally threaded and is provided with at least one, preferably four grooves. When the clamp is snapped over the end of the cable, the threads engage the plastic material of the outer jacket and the reinforcing material is held in the grooves.

  • Patent number: 5010531
    Abstract: A light weight and compact geophone assembly for detecting transient seismic signals along orthogonal axes. The geophone assembly having a plurality of geophones arranged within close proximity of each other within a compact housing. The geophones are interconnected to a conductor cable passing through the housing in a unique water-tight sealing arrangement. At the cable entrance into the housing, the conductor cable is surrounded by a tapered boot compressed about the cable by a sleeve which in turn is fixed in place by a locking nut. The locking nut is received by complementary threads at the cable entrance into the housing. When tightened, the locking nut forces the compression sleeve over the tapered surface of the boot, compressing the boot about the cable. In addition, the locking nut and compression sleeve urge the boot in compression between the cable and the housing. Located atop of the housing is a bubble leveling device.

  • Patent number: 4973370
    Abstract: Braided fine wire cable is prepared for termination by electrical terminals by a coating of dielectric material such as curable varnish which coats and embeds the myriad of fine wires. The coating upon hardening imparts structural integrity to the otherwise very flexible cable, enabling handling. The coating also retains the wire portions many of which may be severed during application of electrical terminals thereto to obtain electrical connection of portions of the terminals with ends or surfaces of many of the wires, thus preventing disintegration of the cable's termination region when the terminals are applied. The hardened coating also enables the cable region to be shaped and formed to some extent, even including cutting or notching the cable, to adapt the cable region to the structure of the terminals, enabling use of existing terminals used for terminating solid flat conductor cable, for example.

At least a portion of the conductors are covered by an adhesive, with the notches extending into the adhesive.

  • Patent number: 4229613
    Abstract: The invention relates to a hose of rubber or rubber-like elastic material adapted to convey pressurized medium and provided with a number of insulated, electrically conductive stranded metal wires embedded in the outer layer of the hose and contributing to its mechanical strength. Use of such a hose is desirable to transmit control signals or other electrical current from one end of the hose to the other by way of the stranded metal wires without obstructing the flexibility of the hose. An end connector means having a metal connector fitting, a shrunk-on sleeve in contact with the metal connector fitting, and a protective cover around the hose itself provides a means for joining the conducting hose to another flexible hose or suitable connecting member.

  • Patent number: 4150247
    Abstract: An electrode for electroslag remelting is provided by combination of an ingot having a toe end with an essentially flat outer annular surface and a central protrusion together with a current-carrying stub bridging across the central protrusion and welded to the flat portion of the ingot toe end on opposite sides of the protrusion such that metal wastage and surface preparation costs for stub-to-ingot welding are avoided.

  • Patent number: 4098663
    Abstract: An anode connector for use in an impressed current cathodic protection system comprising a cup-shaped housing member made from a material which is permanent under anodic conditions with a plug insert member with a central aperture made from conventional current carrying metals which is press fit into the cup-shaped housing. The cup-shaped housing can then be welded to an anode. A cable conductor for the anode which is well insulated except for the end is positioned with the uninsulated end in the central aperture of the plug insert and soldered thereto to provide excellent electrical conductivity between the cable and the plug. The cup is then filled with suitable insulating potting material which covers the plug and the cable conductor to a height above where the insulation begins. This invention provides a rigid, reliable anode connector which is able to withstand anodic conditions in an impressed current cathodic protection system while still providing the current to the anode.

  • Patent number: 4076608
    Abstract: An oxygen sensor comprises an electrolyte which is shaped into a conical tube having a closed end of small diameter and an open end of large diameter. The wall thickness of the electrolyte is gradually decreased toward the closed end from the open end and that of the closed end is 0.3 to 1.0 mm so as to provide a high sensitivity.

  • Patent number: 4056679
    Abstract: A corrugated flexible thin copper tube filled with sodium has a resilient flexible core along the axis thereof so arranged that it will contract and expand to take up the force of thermal expansion and contraction of the sodium. Since the coefficients of expansion of the sodium and copper are different, the absorption of this differential in force by the core prevents rupture of the copper tube and the formation of voids and hot spots within the copper tube.

  • Patent number: 4047783
    Abstract: A special purpose electrical connector. It is for connecting an end of a resistive type of electrical conductor so as to have maximum electrical and mechanical properties.The resistive conductor has a resilient material core of desired resistivity which is surrounded by an insulator. A pair of conductive material wires are applied in a cooperative manner with one wire extending doubled for a substantial distance into the core. The other wire wraps around the outside of the insulator and pierces through to join the first within the resilient core, before extending axially beyond the end of the core and insulation.

  • Patent number: RE31559
    Abstract: The method and apparatus of the present invention are described in which connection (and disconnection) of a plurality of geophones associated with a digital seismic data acquisition system is greatly simplified without sacrificing flexibility as to the number of geophone flyers per station or the interval spacing per station and also without the addition of separate subcabling in the internal linkage of the flyers to the field digitizing equipment. The apparatus includes a multiple-phone flyer-jumper connected to each channel of a remote data acquisition and telemetering circuit (RDATC). Each RDATC acts in combination with a group of geophone flyers, say four, to store, amplify, filter, gain control and digitize analog data from the flyers and then telemeter the data to recording circuitry in the field truck. In accordance with the present invention, each jumper-flyer includes a central multi-conductor cable segment terminating at each of its ends in the central leg of a multi-armed connector.
