US Patent:

20120018421, Jan 26, 2012

Filed:

Apr 2, 2009

Appl. No.:

13/262374

Inventors:

David G. Parman - San Ramon CA, US
Lawrence White - Newark CA, US

Assignee:

TYCO THERMAL CONTROLS LLC - Menlo Park CA

International Classification:

H05B 6/10

US Classification:

219546

Abstract:

A skin-effect heater cable has inorganic ceramic insulation. The heater cable has at least one core conductor wire within a sheath. Electricity is directed through the core conductor in an outward path and returns along a surface “skin” of the sheath in a return path for generating heat.

Assignee:

PENTAIR THERMAL MANAGEMENT LLC - Menlo Park CA

International Classification:

H05B 3/02

US Classification:

219553, 29611

Abstract:

A mineral insulated heating cable for a heat tracing system. The heating cable includes a sheath having at least a first, and optionally a second layer, wherein the thermal conductivity of the second layer is greater than a thermal conductivity of the first layer. In addition, the first and second layers are in intimate thermal contact. The heating cable also includes a least one heating conductor for generating heat and a dielectric layer located within the sheath for electrically insulating the heating, conductor, wherein the sheath, heating conductor and dielectric layer form a heating section. In addition, the heating cable includes a conduit for receiving the heating section. Further, the heating cable includes a cold lead section and a hot-cold joint for connecting the heating and cold lead sections. In addition, a high emissivity coating may be formed on the first layer.

International Classification:

B32B 3100
F16L 914

US Classification:

156165

Abstract:

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.

International Classification:

C08F 200
C08G 8500

US Classification:

526 65

Abstract:

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.

International Classification:

H05B 344

US Classification:

219544

Abstract:

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.
