Abstract:
A steel cord (10) adapted for the reinforcement of rubber products, the steel cord (10) comprises a core (12) and three or more outer strands (14) twisted around the core (12) in a cord twisting direction. The outer strands (14) comprise outer filaments (16) twisted in a strand twisting direction which is the same as the cord twisting direction. The outer strands (14) have a wavy form which makes spaces between the core (12) and the outer strands. The steel cord (10) has improvements on elongation at break and impact resistance capacity.
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 hybrid layered cable for use in tire reinforcement includes a non-metallic internal layer and an unsaturated external layer including 3-12 strands. Each strand is at least partly metallic and is helically wound around the internal layer. Each strand includes at least 3 filaments wound helically together. The cable has a relative elongation at break, measured in tension in accordance with the standard ISO 6892 of 1984, which is higher than 7%.
Abstract:
A rope comprising a plurality of bundle groups, each of said bundle groups having a periphery and comprising a plurality of high strength fibers, at least one low coefficient of friction fiber disposed around at least a portion of the periphery of at least one of the bundle groups.
Abstract:
A large diameter rope having improved fatigue life on a sheave, pulley, or drum is disclosed. This rope includes a blend of HMPE filaments and liquid crystal polymer filaments selected from the group of lyotropic polymer filaments and thermotropic polymer filaments. The rope may be constructed as a braided rope, a wire-lay rope, or a parallel core rope.
Abstract:
A high strength abrasion resistant surgical suture material with industry standard knot tying characteristics and color marking characteristics includes a core formed of a plurality of twisted fibers of a first material, surrounded by a braided cover including a first material sheathed in or coated by a second material different than the first material. The first material is preferably ultrahigh molecular weight polyethylene and the second material is preferably a polymeric material having good knot-tying characteristics.
Abstract:
A pneumatic tire comprises a cord-reinforced layer such as carcass, belt, bead reinforcing layer which is made of metallic cords, each metallic cord is made up of six to twelve metallic filaments whose diameter is in a range of from 0.15 to 0.45 mm, the metallic filaments include waved filaments and unwaved filaments, each waved filament is two-dimensionally waved at a wave pitch and wave height before twisted, the wave pitch is in a range of from 5.0 to 35.0 times the diameter of the filament, and the wave height is in a range of from 0.2 to 4.0 times the diameter of the filament, and the metallic filaments are twisted together into the cord at a twist pitch of from 10 to 40 mm so that the two-dimensionally waved filaments are each subjected to a certain rotation around its axial.
Abstract:
A light weight cable bead core 30 is described having an inner core 33 made of a metal wire 34 with an outer sheath 35 of steel cord wires 36. Each cord 36 is made of a plurality of filaments 37. The bead core 30 is particularly suited for heavy-duty service conditions in tires 100 for aircraft, off-road equipment, and commercial trucks.
Abstract:
A pneumatic tire comprises a bead core formed by laminating three or more sheath layers of spirally twisted sheath filaments around a thick core wire and making reverse the twisting direction of the sheath filament in these sheath layers every the sheath layer, in which the number of twisting pitches in the sheath filament of a second sheath layer viewed from the outermost side is made smaller than that in sheath filament of a sheath layer located inward from the second sheath layer.
Abstract:
A rope comprising a plurality of wires (2, 3, 4) made of a steel wire being twisted together; at least the wires which are arranged in such a manner as to be disposed on an outer surface of the rope (1) being made of a plated steel wire wherein a corrosion resistance is superior; at least said wires which are located in a center of the rope not being made of the wire wherein the corrosion resistance is superior.
