Patent number: 8367933Abstract: A communication cable can comprise twisted pairs of electrical conductors for transmitting electrical signals, such as for digital communication or data transmission. The pairs can be twisted to different lengths, thereby managing interference among the pairs. The electrical conductors of the pairs can be individually insulated with a polymeric material comprising a base polymer that is foamed with a gas such as nitrogen. The respective foaming levels of the electrical conductors in each pair can be selected to balance electrical properties among the pairs.Type: GrantFiled: June 18, 2010Date of Patent: February 5, 2013Assignee: Superior Essex Communications LPInventors: Jeffrey H. Mumm, Justin W. Mintz, Nathaniel Ostrander

Patent number: 8162546Abstract: A connectorized fiber optic communications cable can comprise a section rated for indoor service and a section rated for outdoor service. A continuous optical fiber can extend through the indoor-rated section and the outdoor-rated section, for example from an outdoor-rated connector on the outdoor-rated section to an indoor-rated connector on the indoor-rated section. The cable can be installed via feeding the section rated for indoor service through a hole in a building, such as a home, to a communication or computing device within the building. The section rated for outdoor service can be buried underground and extended to another communication or computing device located outside the building.Type: GrantFiled: March 31, 2009Date of Patent: April 24, 2012Assignee: Superior Essex Communications, LPInventors: Jeffrey H. Mumm, Jeffrey S. Laws, George Bell

Patent number: 7813605Abstract: A data communication cable can comprise multiple pairs of twisted conductors. A jacket that extends along the outside surface of the cable can define a longitudinal core, internal to the cable. The conductor pairs can be disposed in the core of the cable along with a foam matrix or a porous filler, with the matrix and the conductors occupying essentially all of the volume of the core. The foam matrix can hold each conductor pair in a respective location within the cable core to control signal crosstalk on each pair. A co-extrusion process can produce the cable via simultaneously extruding the foam matrix and the jacket. A pulling apparatus can feed the conductor pairs though respective ports of an extrusion head-and-die assembly. As one extruder encases the moving conductor pairs in the foam matrix, another extruder forms the jacket over the matrix and the embedded conductors.Type: GrantFiled: April 7, 2009Date of Patent: October 12, 2010Assignee: Superior Essex Communications, LPInventor: Jeffrey H. Mumm

Patent number: 7018492Abstract: Tufted carpets bonded with thermoplastic binders and having improved resistance to fuzz formation due to removal of pile yarn filaments from tuft bundles comprise one or more backings, face yarn that forms a pile on one side and stitches on an opposite side, a thermoplastic binder that binds stitches and the backing or backings, and an organic polymer that bonds filaments of the stitches. Processes for making carpets comprise applying to a stitched side of a tufted backing a liquid stitch bind composition comprising an organic polymer component, removing a liquid component of the composition to bond filaments of the stitches and bonding stitches and one or more backings with a thermoplastic binder that is melted or applied as a melt in contact with the stitched side and the backing or backings and solidified.Type: GrantFiled: October 25, 2000Date of Patent: March 28, 2006Assignee: Propex Fabrics, Inc.Inventors: Jeffrey H.
