Abstract:
Disclosed is a method for producing a high strength synthetic strength member (7) containing rope (1) capable of being used with powered blocks where such rope has lighter weight and similar or greater strength than steel wire strength member containing ropes used with powered blocks. Disclosed also is the product resulting from such method. The product includes a synthetic strength member, a first synthetic portion (9) and a second synthetic portion. The first synthetic pillion is enclosed within the strength member and the second synthetic portion is situated external the strength member. At least a portion of the second synthetic portion also is situated internal a sheath (8) formed about the strength member. The second synthetic portion has a minimal of 8% at a temperature of between negative 20 and negative 15° C.
Abstract:
Hybrid rope (1) having a core containing synthetic yarns (5), surrounded by an outer containing steel wire strands (5), the rope being terminated at least at one of its ends by a socket (2) having a conically shaped space (3), which has a conical angle α of between 2 and 8° and a length of between 5D and 20D, D being the smallest diameter of the conically shaped space, the core containing synthetic yarns and the steel wires having been untwisted at said at least one of the ends, the open space (6) around the untwisted wires and fibers in the hollow conical body of the socket being filled with a resin.
Abstract:
An object of the invention is to provide a high strength and light hybrid rope. At the center of the hybrid rope 1, there is arranged a high strength synthetic fiber rope 3 formed by braiding multiple high strength synthetic fiber bundles 30 each composed of multiple high strength synthetic fiber filaments 31. Given that the pitch of braid of the high strength synthetic fiber bundles 30 is represented by “L” and the diameter of the high strength synthetic fiber rope 3 is represented by “d”, the pitch of braid “L” and the diameter “d” are adjusted such that the value L/d is equal to or higher than 6.7.
Abstract:
A method for forming a helix rope for a trawl comprising the steps of: a) situating upon a portion of a rope a bead of a substance being selected from a group consisting of: (i) a liquid substance; and (ii) a semi-liquid substance. A helix rope (35) for forming portions of a pelagic trawl, the helix rope comprising a braided sheath (398) formed of greater than sixteen strands (397), whereby drag is reduced. A method for forming a high strength synthetic rope useful for towing warps, trawler warps, yachting ropes, mooring lines, anchoring lines, oil derrick anchoring lines, seismic lines, paravane lines, and any other uses for rope, cable or chain.
Abstract:
A fast rope, which includes a weighted core, a first braid surrounding the core, a second braid surrounding the first braid, and a third braid surrounding the second braid. The core is constructed from lead wires extruded over a polyester yarn, the first braid is strands of polypropylene, the second braid is strands of composite press material, and the third braid is strands of spun polyester.
Abstract:
There are provided an annular concentric stranded bead cord which can realize a reduction in weight while ensuring its strength, a method for manufacturing the same and a vehicle tire.The manufacturing method is a method for manufacturing an annular concentric stranded bead cord by forming a sheath layer by winding spirally a lateral wire round an annular core. After the sheath layer has been formed, the lateral wire is annealed in a pressure-reduced inactive gaseous atmosphere with an annealing quantity which exceeds a heating quantity (temperature×time) which is necessary for vulcanization of a vehicle tire with the annular concentric stranded bead cord embedded in a rubber of the vehicle tire when building the same and is shaped so that “Diameter shaping ratio (%)=H/D×100” becomes 20% or larger and 105% or smaller.

Abstract:
A rope having an outer jacket made of braided fibers surrounding a PTFE core and a method for making the rope. The rope is useful in high-tension, high-friction applications, such as serving as a stress member in an isolation section of an instrumented ocean-bottom cable. The PTFE core, which may consist of one or more strings of PTFE valve packing material, squeezes through the braided jacket as the rope is deformed in high-stress regions such as around a bollard. The PTFE material squeezed through the outer jacket lubricates the outside of the rope in the high-stress region to lower the friction.
Abstract:
A wire cord for reinforcing rubber items, more particularly pneumatic tires for cars and trucks, comprises at least three wire filaments 2 arranged about a continuous core filament 3. The core filament 3 consists of a non-metallic material capable of longitudinal contraction when the rubber item 5 to be reinforced is vulcanized, this material being more particularly non-drawn nylon. On vulcanization of the rubber item 5 to be reinforced the core filament 3 contracts and expands in diameter.
Abstract:
Disclosed herein is an endoscopic extraction device which retains its operative usefulness for longer periods of time, and therefore need to be replaced less frequently. This extended instrument life is accomplished through the use of a composite wire construction, which includes, an inner monofilament wire of nitinol material surrounded by six stranded stainless steel wires. A wire construction in which a nitinol wire is surrounded by five stranded stainless steel wires is also disclosed. After constructing a wire basket in the normal manner using this material, heat is applied to the formed basket in its pre-formed shape to set the memory characteristics of the inner nitinol core.
Abstract:
A composite fishing line comprising a core and braided jacket the core being made of material which will break under a predetermined tensile loading of the line, said braided jacket being made of a different material which does not break under said predetermined tensile loading and having a braid tightness which permits reoccurrent breaks in the core under the reoccurrence of said tensile loading without affecting the utilization of the line.
