Abstract: An electrical connection with first and second electrical connectors are adapted to engage each other to form an electrical connection. An electrical wire is connected to each connector. At least one of the connectors has a contact formed of a conductive elastomeric material with conductive particles dispersed in the material, which is shaped to deform when compressed. When the first and second connector elements engage each other contact(s) formed of the elastomeric material will deform to cause electrically conductive particles in the elastomeric material to form an enhanced electrically conductive path through the elastomeric material.

Abstract: The present invention relates to a seal for an electric cable that is connected to a second cable in a confined location, in which a first and second lengths of insulated electrical cable extend into a confined location and a connector connects the first and second lengths of cable, and a method for forming such a seal. A thin layer of conductive material covers a first portion of the first length of insulated electrical cable, with a second portion of the insulated electrical cable projecting beyond the conductive material for connection to the connector and providing an exposed end of the conductive material.

Abstract: A scoring tool and method are described which are useful in removing a portion of an outer lead sheath of an electrical cable conductor. The tool includes a substantially C-shaped tool for straddling the conductor and a scoring wheel supported by the frame. The tool is used to form both longitudinal and circumferential score lines in the outer surface of the sheath. A strip formed between the longitudinal score lines can be gripped, rolled up and removed. The remaining portion of the lead on either side of the score lines can then be removed.

A drain or vent to the atmosphere is also located between the seals.

Abstract: A method for inserting at least one conductor into an elongated length of metal coiled tubing, includes the steps of placing the coiled tubing in a substantially vertical passageway, inserting the conductor into the tubing, the leading end of the conductor including an elongated weight connected to the conductor, which weight is heavy enough to straighten the conductor enough to fall through the tubing, the weight having essentially no stiffness so that it is flexible enough to move through bends or irregularities in the tubing, allowing the conductor and weight to fall by gravity through the tubing, which has a sufficient helical pitch providing a hold-up force due to friction for preventing the conductors from breaking, until the desired length of conductor is inserted in the tubing, and removing the tubing with the conductor inside the tubing from the passageway and winding the tubing on a reel.

Abstract: An automated data transmission system for communicating warning signals and other information directly to law enforcement or security personnel in order to reduce response times. In the disclosed embodiment of the invention, sensing circuitry is added to a standard security system installed at an industrial or residential site. The sensing circuitry detects activation of the security system by sensing an outgoing warning call. Following activation of the security system, an automatic dialer or other automated transmitter circuitry is used to initiate a call to a processing computer at a predetermined phone number. The processing computer utilizes Caller ID.TM. information to determine the phone number assigned to the automatic dialer.
