Patent number: 7196271Abstract: Generally, aspects of embodiments of the invention include cable separator spline which comprises a plurality of longitudinally extending walls joined along a central axis of the spline, and a plurality of longitudinally extending channels. Each longitudinally extending channel is defined by a pair of the longitudinally extending walls, where the pair of longitudinally extending walls includes a first wall substantially thicker than a second wall. Other embodiments include a cable separator spline assembly having a plurality of longitudinally extending walls joined along a central axis of the spline, and a plurality of longitudinally extending channels. Each longitudinally extending channel is defined by a pair of the longitudinally extending walls, wherein a pair of opposing longitudinally extending walls have defined through them a common gap defining two separate sub-splines having T-shaped cross-sections.Type: GrantFiled: March 3, 2003Date of Patent: March 27, 2007Assignee: Belden CDT (Canada) Inc.Inventors: Jacques Cornibert, Jorg-Hein Walling, Christian Yameogo

Publication number: 20060113106Abstract: An insulated wire for use in a communications cable, the wire comprising a conductor, at least one inner insulating layer surrounding the conductor, and an outer layer surrounding the insulating layers. At least one of the inner layers is a nano-composite comprising nano-sized platelets and a flame and smoke retardant additive package dispersed in a polyolefin matrix. The outer layer is substantially resistant to flame spread and smoke evolution, substantially impermeable to moisture and moisture absorption and has a dielectric constant lower than about 2.5 and a dissipation coefficient lower than about 0.001 at frequencies up to about 650 MegaHertz.Type: ApplicationFiled: January 11, 2006Publication date: June 1, 2006Applicant: NORDX/CDT, INC.Inventors: Gavriel Vexler, Jacques Cornibert

Patent number: 6365836Abstract: A cross web core in a high performance data cable maintains geometric stability between plural twisted pair transmission media and between each twisted pair and the cable jacket. The cross web core may further isolate twisted pairs from each other by including conductive or magnetically permeable materials. By so doing, loss, impedance and crosstalk performance are improved.Type: GrantFiled: June 30, 1999Date of Patent: April 2, 2002Assignee: Nordx/CDT, Inc.Inventors: Denis Blouin, Jacques Cornibert, Jörg-Hein Walling

Patent number: 5077449Abstract: An electrical cable having a jacket surrounding a metal shield which, in turn, surrounds the cable core. The jacket comprises a polyolefin with a modifier provided by a carboxylic acid or anhydride thereof with the jacket lying in intimate overall contact with an outer surface of the shield and being bonded by the modifier throughout the overall contact areas to the shield.Type: GrantFiled: September 20, 1990Date of Patent: December 31, 1991Assignee: Northern Telecom LimitedInventors: Jacques Cornibert, Jorg-Hein Walling, Ranier A. Minzloff, Marek Kapuscinski, Serge Nadeau

Patent number: 5011880Abstract: Fire retardant and water blocking material for cables having an admixture, in parts by weight, of 100 parts of amorphous polypropylene, which is in a continuous phase throughout the composition, from 10 to 70 parts of hydrated inorganic oxide or hydroxide material, and an organic halogenated material and antimony trioxide, the aggregate of the organic halogenated material and antimony trioxide being from 5 to 30 parts.Type: GrantFiled: May 4, 1989Date of Patent: April 30, 1991Assignee: Northern Telecom LimitedInventors: Jacques Cornibert, Jorg-Hein Walling

Patent number: 4980001Abstract: In a method of applying a jacket to a metal shield of a cable, the jacket comprises a polyolefin having a modifier provided by a carboxylic acid or its anhydride. As the jacket extrudate passes onto the shield, air pressure is lowered at the surface of the shield to provide intimate overall contact between jacket and shield. Heating, additional to that provided by the extrudate, is employed to raise the outside bonding temperature of the shield up to at least the bonding temperature of the modifier so as to provide a bond between the jacket and the shield.Type: GrantFiled: November 13, 1989Date of Patent: December 25, 1990Assignee: Northern Telecom LimitedInventors: Jacques Cornibert, Jorg-Hein Walling, Rainer A. Minzloff, Marek Kapuscinski, Serge Nadeau

Patent number: 4710594Abstract: A telecommunications cable having no metal sheath, but having a plurality of equally pre-tensioned and inextensible tensile members embedded in the cable jacket. These members are spaced apart around the core and extend longitudinally of the cable to apply an axially compressive force upon the jacket. The members may be glass fibers and each member is preferably a roving of fibers. The filaments may be coated with a material which sticks them to the jacket and the core may be filled with a moisture blocking material.Type: GrantFiled: June 23, 1986Date of Patent: December 1, 1987Assignee: Northern Telecom LimitedInventors: Jorg-Hein Walling, Jacques Cornibert, Gordon D.
