An umbilical according to an embodiment of the invention may include a plurality of steel tubes helically wound around a core, and at least one substantially solid steel rod helically wound around the core, the steel rod being arranged in a void between the steel tubes. Thus, the invention avoids the need to apply additional armoring layers to the outside of the umbilical for strength and ballast.

A system and method are provided for displaying electronic devices operable when electrical power is supplied to them at respective operating voltages through respective power connectors. The system has a power supply providing input electrical current at a first voltage and cable structures each connected with the power supply and having a respective power connector electrically connecting with the power receiving structure of one of the electronic devices. The cable structures each include a voltage regulator system that receives the input electrical current, converts it to an output electrical current at an output voltage, and transmits it to the power connector, so as to transmit an operating electrical current to the associated electronic device. The voltage regulator system sets the output voltage of the output electrical current such that the operating electrical current delivered to the associated electronic device has a voltage that corresponds to the operating voltage of that device. This is accomplished by connecting the voltage regulator to a calibrating component with a selected electrical characteristic that sets the output voltage. A security circuit creates an alarm when separation of the electrical device from the system occurs.

A low odor grip is disclosed for a handle of a hand-held implement such as a sports implement or a manual or electric tool which is essentially free of disagreeable odors, which can be installed and quickly shrunk into a tight vapor resistant grip within a matter of a few minutes rather than requiring extended periods of time, and can be installed without the need for any application of heat or use of special tools, equipment or materials.

A substrate including a plurality of monofilaments, or a combination of monofilaments and multi-filament yarns oriented in perpendicular directions, has a tendency to curl around a central space. When all monofilaments are used, the monofilaments along one direction may have a larger diameter than the monofilaments along the other direction. The monofilaments are woven such that the larger diameter monofilaments form floats predominantly on one side of the substrate. For the monofilament-multifilament combination the monofilaments form floats predominantly on one side of the substrate. The substrate curls about an axis parallel to the monofilaments forming the floats. The side having the floats faces outwardly away from the central space. Preferably, the monofilaments are oriented in the warp direction along the substrate. The filaments may be woven in a herringbone twill weave, a double cloth herringbone twill weave or a satin weave to provide the floats.

A connector axial compression tool having a lever end and a cable end, with a body slidably supporting a cradle in a cavity formed in the body. The cradle is slidable via a handle which pivots about the body, linked to the cradle by a lever mechanism. The cradle has a shoulder clamp adapted to mate with a connector body. Operation of the handle moves the cradle towards and away from a cable end of the cavity, against a cable clamp through which the cable may pass but against which a cable clamp sleeve of the connector abuts, axially compressing the connector to couple it to the cable. Because the shoulder clamp holds the connector body rather than pressing against the connector interface, a wide range of different connectors may be used with the same tool, without causing damage to the connector interface of the various connectors.

This invention relates to collet-type splices and collet-type dead ends and methods for splicing together two aluminum conductor composite core reinforced cables (ACCC) or terminating one ACCC cable. The collet-type fittings use a collet inside a collet housing to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet and the composite core. After inserting the composite core into the collet, a compression implement compresses the collet. The collet holds the composite core with frictional forces and the collet further compresses and strengthens the hold on the composite core if the composite core pulls the collet further into the collet housing.

A high-pressure connector for an electrical power cable segment having a central stranded conductor encased in a polymeric insulation jacket with an interstitial void volume in the region of the conductor. The connector confines a fluid within the interstitial void volume at a residual pressure above atmospheric, but below the elastic limit of the insulation jacket. A housing interior chamber receives the conductor in fluid communication with the interstitial void volume. Some embodiments have the chamber sized to receive and overlap a portion of the insulation jacket with a housing end portion swaged thereto. A seal seals the insulation jacket with respect to the housing and a retaining member secures the cable segment to the housing to prevent pushback of the insulation jacket at the residual pressure.
