Patent number: 8563864Abstract: A smooth-bore plastic tubing with an outer helical support bead is resistant to collapse and incorporates plural conductors disposed outside of the tubing bore and insulated both from ambient and from one another. The conductors may have a desired relatively high thermal conductivity to tidal air flow within the tubing, while also having a comparatively high thermal resistance to ambient. The conductors may be electrical conductors, or may include fiber optic conductors as well in the same tubing structure. A method for making the tubing includes extruding a molten thermoplastic ribbon. The plastic ribbon is wrapped to form a tubular body, and a grooved plateau portion is wrapped upon the tubular body. At least one conductor is embedded in the groove of the plateau portion.Type: GrantFiled: April 30, 2011Date of Patent: October 22, 2013Inventor: Eric Carlson

Patent number: 8558115Abstract: Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.Type: GrantFiled: March 1, 2010Date of Patent: October 15, 2013Assignee: Panduit Corp.Inventors: Royal O.

Publication number: 20120211255Abstract: There is disclosed an animal-resistant wiring system. The animal-resistant wiring system may include a cable disposed within a coil shield, the coil shield having a uncompressed length longer than a length of the cable. The coil shield may have an inside diameter larger than an outside diameter of the cable. The entire length of the coil shield may be free to move radially, axially and rotationally about the cable except that first and second terminations coupled to the ends of the cable may prevent first and second ends, respectively, of the coil shield from moving axially beyond the ends of the cable, such that the length of the coil shield is compressed between the first termination and the second termination.Type: ApplicationFiled: April 17, 2012Publication date: August 23, 2012Applicant: Senet Partners LLCInventor: Bradley Senet
