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.

Abstract: An arrangement to conduct electrical power from a non-hazardous area through plural electrical conductors to the electrical conductor of a power cable which extend through a sealed barrier in a wellhead in a hazardous area including a rigid conduit with a power source electrical conductor therein extending into the hazardous area from an adjacent non-hazardous area for conducting electrical power to a downhole electrical conductor in the hazardous area, said rigid conduit including a seal fitting, splice fitting connected with said seal fitting and positioned adjacent the wellhead for receiving the ends of the power source electrical conductor and the ends of the downhole electrical conductor extend through the sealed barrier in the wellhead for splicing them together.
