Publication number: 20160079685Abstract: A method of cold joining a first cable and a second cable may include providing a connector having both right hand and left hand threads. The first cable may have a right hand threads on its core, while the second cable may have left hand threads along its core. The first and second cables may be simultaneously connected to the first and second cables to the connector by rotating the connector. The connector may then be crimped to permanently, or at least semi-permanently retain the first and second cores within the connector.Type: ApplicationFiled: September 17, 2014Publication date: March 17, 2016Inventors: Scott M.

Patent number: 6288372Abstract: An electrical cable device such as a heating cable includes a braidless ground return layer surrounding an inner jacket. The ground return layer is formed by a conductive polymer and a ground return wire connected to the conductive polymer. The polymer may be made suitably conductive for ground fault detection by addition of a particulate conductive filler such as carbon black, carbon fibers, or a blend thereof.Type: GrantFiled: November 3, 1999Date of Patent: September 11, 2001Assignee: Tyco Electronics CorporationInventors: Chester L. Sandberg, Albert J. Highe, Jose Gamarra, Lawrence J. White, Frank Orecchia, Ted M. Aune

Patent number: 5622642Abstract: An apparatus for sealing the end of an elongate cable such as an electrical heating cable which comprises a clip-shaped insert positioned within a tubular-shaped housing. Gripping members and pre-gripping members project from the interior surfaces of the arms of the insert and act to grip a cable when it is inserted into the device. A locking mechanism on the insert engages locking teeth on the housing and serves to hold the insert in position. A conformable gel component may be present. The apparatus provides high pullout force, as well as environmental sealing, for cables such as electrical heating cables or power cables.Type: GrantFiled: February 6, 1995Date of Patent: April 22, 1997Assignee: Raychem CorporationInventors: Larry M. Edwards, Lawrence J. White, Timothy O. Stixrud, deceased

Patent number: 4912181Abstract: Poly(arylene ether ketones) are prepared by a Friedel-Crafts polymerization wherein a gelled reaction mixture is produced, by permitting the polymerization to proceed in a first reactor until substantial partial polymerization has occurred, but before substantial gelation of the reaction mixture; transferring the partially polymerized reaction mixture into a piston-equipped second reactor; permitting polymerization to continue in the second reactor until a gelled, polymerized reaction mixture has been obtained; and discharging the polymerized reaction mixture from the second reactor by stroking the piston.Type: GrantFiled: May 9, 1988Date of Patent: March 27, 1990Assignee: Raychem CorporationInventors: Paul Becker, Larry M. Edwards, Patrick J. Horner, A. Brian Macknick, Stephen Moore, Ronald J. Mosso, Lawrence J. White

Patent number: 4432824Abstract: The invention is a method and device for providing a protective coating for the inside of pipes, said method utilizing a device which is remotely actuated from outside said pipes. Specifically, the device comprises a memory metal delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.Type: GrantFiled: July 26, 1982Date of Patent: February 21, 1984Assignee: Raychem CorporationInventors: Paul M. Cook, Richard F. Otte, James L. Claypool, Lawrence J. White, Harry C. Broyles, Peter L. Brooks

Patent number: 4424990Abstract: This invention provides novel thermochromic compositions which exhibit distinct color changes at temperatures in the range of about 165.degree. C. to about 240.degree. C. The compositions comprise basic copper carbonate and a sulfur compound. Paint formulations containing these novel thermochromic compositions or complexes of copper and sulfur-containing organic acids are also provided. The compositions are useful with heat-recoverable memory metal couplings to prevent overheating of the couplings during installation.Type: GrantFiled: November 25, 1981Date of Patent: January 10, 1984Assignee: Raychem CorporationInventors: Lawrence J. White, Tamar G. Gen

Patent number: 4386629Abstract: A device for providing a protective coating for the inside of pipes, said device being remotely actuated from outside said pipes. Specifically, the device comprises a high modulus engineering plastic delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.Type: GrantFiled: July 7, 1981Date of Patent: June 7, 1983Assignee: Raychem CorporationInventors: Paul M. Cook, Richard F. Otte, James L. Claypool, Lawrence J. White, Harry C. Broyles, Peter L. Brooks

Patent number: 4344214Abstract: The invention is a remotely thermally activatable device for delivering a payload to a pre-determined location within a pipe comprising a carrier means for supporting the payload, a driver means to axially move the carrier means, and a thermally activatable trigger means connected to the driver means to actuate the driver means. In operation, the device and payload may be placed in a location within a pipe, for example, near the end of a pipe to be welded to an adjoining pipe. Subsequent to such welding, the instant invention may be remotely activated by outside heating of the pipeline in the vicinity of the device, thereby causing the device to move the payload to the pipe weld.Type: GrantFiled: July 31, 1980Date of Patent: August 17, 1982Assignee: Raychem CorporationInventor: Lawrence J.
