Abstract:
Methods are provided for forming a spliced eye (220) of a sling (222) made from a rope that includes a core rope (37) and includes a braided sheath (398).
Abstract:
A cord material suitable for use in lined textile structures with a gliding component includes a plurality of uniform strands, and a deviant strand. The deviant strand is different from the uniform strands in some characteristic affecting aerodynamic or hydrodynamic properties of the cord, such as size or surface properties. Each uniform strand can have a substantially equal cross section area, while the deviant strand has a cross section area at least five times greater than one of the uniform strands. The strands can be braided or woven together. A major benefit of the material can be that vibration induced drag is significantly reduced or eliminated in lines made with the material. Another advantage is that lines made from the material can have more consistent, predictable line drag, which can improve the quality of handling.
Abstract:
A rope and a method of constructing the rope. The rope may be of 12×12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.
Abstract:
A dynamic stabilization system for stabilizing a vertebral segment of a spine. The system includes a first vertebral anchor, a second vertebral anchor and a cord. The system may also include a spacer positioned between the first and second vertebral anchor through which the cord extends. The first vertebral anchor is configured to be secured to a first vertebra and the second vertebral anchor is configured to be secured to a second vertebra. The cord is extendable from the first vertebral anchor to the second vertebral anchor. The cord has a variable stiffness through a range of displacement, wherein the stiffness of the cord increases as an applied tensile force on the cord is increased.
Abstract:
The abrasion resistance of organic fiber based ropes and cords is increased by a outer woven cover of tapes of high molecular weight and more preferably ultrahigh molecular weight polyethylene
Abstract:
Disclosed is an improved tension member or slickline used in wellbore intervention operations. One exemplary tension member includes a first portion comprising a metallic material and having a distal end, a second portion comprising a non-metallic material and having a proximal end, and a joint coupling the proximal end of the second portion to the distal end of the first portion.
Abstract:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet/greasy conditions.
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 portion 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:
A colored suture includes an elongate woven braid of filaments including one or more ends made of an ultra high molecular weight polyethylene (UHMWPE). The suture also includes second and third ends which can be colorable or dyeable before or after incorporation into the elongate woven braid. This invention provides surgeons with improved recognition of suture ends in surgery by construction of a bi-colored co-braid with at least two ends of different color schemes or patterns braided into a UHMWPE construction. One of the colored ends runs continuously from one end of the suture to the other end. The other colored end can be colored only on one half of the end. This provides a suture with two distinguishable ends, while still maintaining a continuous line of color along the length of the suture.
Abstract:
The invention relates to a paper guide rope (1) braided from a plurality of textile subunits (2, 2′, 2″), wherein each subunit contains a plurality of twisted yarns (3) made from multifilament yarn. The rope according to the invention is characterized in that the titre of at least part of the twisted yarns, preferably of all the twisted yarns, is in each case at most 5000 dtex, and that the twist rate of at least part of the twisted yarns, preferably of all the twisted yarns, is in each case at least 150 T/m.
