Abstract:
L'invention concerne une goulotte (100) comprenant un socle (110) profilé selon un axe longitudinal (X), pourvu d'un fond (111) et de deux ailes latérales (112, 113) qui s'élèvent à partir du fond (111) le long de ses deux bords longitudinaux, le fond (111) comportant sur sa face interne (111A) deux nervures longitudinales (1112, 1113) qui présentent une hauteur faible par rapport à la hauteur des ailes latérales (112, 113) et dont les faces internes définissent entre elles une gorge longitudinale (111E). Selon l'invention, la face interne de chaque nervure longitudinale (1112, 113) est sensiblement plane, et lesdites nervures longitudinales (1112, 1113) sont inclinées l'une vers l'autre.
Abstract:
Described herein are foamable compositions and methods of making foamed compositions. The foamable composition comprises at least one polymer and a foaming agent. The foaming agent comprises a talc or a talc derivative. The polymers described herein comprise a substantially non-halogenated polymer. One or more additives are added to render the compositions flame retardant and/or smoke suppressant. Also described are Power over Ethernet (PoE) cables, having at least one electrical conduit comprising an electrically conductive core, an insulation that at least partially surrounds said electrically conductive core and a polymeric separator extending from a proximal end to a distal end and having at least one channel adapted for receiving the at least one electrical conduit. The PoE cables are capable of carrying about 1 watt to about 200 watts of power.
Abstract:
In various embodiments, a tubular comprises a tubular outer sheath defining an inner void; one or more core elements or assemblies disposed within the inner void; and a substantially solid filler in various embodiments disposed within and substantially filling the inner void, where the filler is adapted to give the tubular hoop strength in a crush situation and comprises a polymer with a density of at least 1.0. In some embodiments, these core assemblies comprise an extruded polymer layer typically extruded about core elements in a single pass, fitting about them without a sharp edge and defining an outer shape. The resulting tubular can comprise multiple regions which, though substantially filled, are filled with differing fillers densities.
Abstract:
A cable trough assembly for housing a cable comprises a cable trough and a cable anchor for anchoring the cable to the cable trough. The cable anchor comprises a stop that guards against the cable anchor being pulled out of the cable trough. Also described is a method of securing a cable in a cable trough, the method comprising laying a cable in the cable trough and attaching the cable to a cable anchor installed in the cable trough.
Abstract:
To provide a structure for mounting a retrofit part to a cladding member that can prevent the retrofit part from causing a turn or positional displacement. A clamp 25 includes a clamp base 26 and a clamp cover 27 continuous to the clamp base 26 by a hinge 26a. The clamp 25 has spike-shaped portions 28. The spike-shaped portions 28 are formed and placed on both a mount surface 31 of the clamp base 26 and a mount surface of the clamp cover 27. The spike-shaped portions 28 are an area that prevents the clamp 25 from causing a turn or positional displacement, and each protrusively formed substantially into a pyramid shape with a pointed end. The spike-shaped portions 28 are formed as an area that bites into an exterior surface of a cladding member and that resists external force, such as vibrations, when the clamp is mounted.
