Abstract:
The present invention is directed to a wire rope having a blackened finish designed for theatrical productions. The wire rope includes a plurality of strands that have a closed spiral arrangement with each other and are compacted. Each strand includes a center wire spirally surrounded by a plurality of inner wires that are spirally surrounded by a plurality of outer wires so that the outer wires completely encompass the inner wires. The center wire and the inner wires are made from a galvanized material and coated with a lubricant. The outer wires are made from a non-coated steel material. Each strand is compacted so the outer wires create a tight mechanical seal to protect the inner wires. The blackened finish on the wire rope is due to a black oxide coating treatment and provides for low visibility of the wire rope during theatrical performances.
Abstract:
A flexible abrasion resistant water shedding omnidirectionally reflective rope has a central low-density polymeric closed cell foam core comprising EPDM, Neoprene, SBR, NBR, EVA, PVC, PVC/NBR foam surrounded by cylindrically braided sleeve of reflective strips composed of narrow width reflective strips that comprise a woven or knitted narrow width strip and a flexible nylon retroreflective sheet sewn thereon and covered with abrasion resistant water shedding coating. The flexible retroreflective sheet is formed by thermally bonding corner cube, microsphere retroreflectors, or wide angle exposed retroreflective lenses to a flexible polymeric sheet. Due to its low-density foam core construction, the reflective rope floats on water and sheds water from the surface preserving omnidirectional reflectivity. The rope reflects light omnidirectionally over a large angle of acceptance and provides accurate illumination of the rope floating in water, location of a rope wound buoy and the like when used during dusk, fog or nighttime hours.

Abstract:
A tether may include a core, a plurality of electrical conductors wound around the core, and a jacket surrounding the plurality of electrical conductors. The plurality of electrical conductors may include at least two groups of electrical conductors. Each group of electrical conductors of the at least two groups of electrical conductors may define a respective electrical path, where the respective electrical path is different from the electrical paths defined by other groups of electrical conductors of the at least two groups of the electrical conductors. Moreover, each group of electrical conductors of the at least two groups of electrical conductors is located around a respective portion of the core, such that a cross-section of each group of electrical conductors of the at least two or more electrical conductors defines a respective arc around the respective portion of the core.
Abstract:
A retroreflective metal wire product (100) is described having a first coating (120) covering the metallic wires (110) wherein retroreflective beads (130) are partly embedded and a protective coating (150) covering said beads (130) and first coating (120). The metal wire product (100) can be made from a metallic strand (102) or wire, the metal being stainless steel, or low carbon steel or high carbon steel. The retroreflective metal wire product can be used for diverse appliances such as spoke wire, signalisation means, bookbinding wire to name just a few.
Abstract:
A flexible omnidirectionally reflective horse lead has a central portion, and mechanical attachment means to accommodate a bridal bit ring. The lead reflects an incoming light beam from a walker or horseback rider back in the direction from which it emanated, preventing dangerous encounters during dusk or nighttime hours. The omnidirectionally reflective elements may be incorporated in a horse harness, or in a halter suitable for horses roaming in a paddock or field. The reflective elements are created by surrounding a central braided rope of nylon or polyethylene fibers with a cylindrically braided reflective sleeve. The braided reflective sleeve is composed of narrow width reflective strips having a show surface with a flexible nylon retroreflective sheet sewn thereto. Reflectivity is achieved by thermally bonding corner cube or microsphere retroreflectors to a flexible polymeric sheet. Due to its braided construction, the reflective elements reflect light omnidirectionally over a large angle of acceptance, illuminating the horse harness or halter. An improved measure of safety is thereby provided for both the horse and the horseback rider.
