Disclosed is a non-steel strength membered high strength cable easily monitored for heat and elongation comprising a length of a core-cable (10), the length of core-cable (10) including at least two fiber-optic conductors (2) that are: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material.
One fiber-optic conductor capable of transmitting at least Raman backscattering and the other fiber-optic conductor capable of transmitting at least Brillouin scattering.

A combination of the cable (10): (i) with an interrogator that can read and interpret Raman backscattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Raman backscattering; and (ii) another interrogator that can read and interpret Brillouin scattering coupled to and communicating with the fiber optic conductor that is capable of transmitting at least Brillouin scattering;
permits ascertaining the elongation of the cable, without using loose tube fiber-opticplacement.

The disclosure provides embodiments of environmentally acceptable fishing lines or fishing nets. Embodiments of the disclosed fishing line or net may comprise a degradable polymer having components derived from i) biomass sources, ii) protein, fatty acid or lipid sources, iii) microbial-based monomers and polymers, iv) agro-based monomers and polymers, v) sugar or starch based monomers and polymers, or combinations thereof, as well as fishing lines and net that further comprise an additive having components derived from i) polyol sources, ii) citrate sources, iii) fatty acid sources, iv) biomass oil sources, or combinations thereof. Some of the embodiments of the disclosed fishing lines or nets may have a suitable fiber core, while other embodiments of the disclosed fishing lines or nets are degradable over a predetermined period of time. The disclosed embodiments are preferred because of the low environmental impact of the disclosed fishing lines or nets when compared to, for example, well known synthetic polymer fishing lines or nets.

A biodegradable seed rope having predetermined positioning of seeds along with nutrients is disclosed. The rope may be made of but is not limited too any organic, biodegradable or water-soluble substantial grass/paper-based composition material. Additionally, the rope is infused with organic fertilizer, nutrients, and minerals to nurture the soil and support the growth of the seeds. The seeds are spaced apart equally along the seed rope. The spacing of the seeds are determined by the type of seed that is placed within the rope.

An exercise rope is disclosed. The exercise rope includes a weighted core. It further includes a first braided layer surrounding the weighted core, the first braided layer having yarns of a first ply. It further includes a second braided layer surrounding the first braided layer, the second braided layer having yarns of a second ply, the second ply being higher than the first ply. It further includes a third braided layer surrounding the second braided layer, the third braided layer having yarns of a third ply, the third ply being higher than the second ply. The second braided layer is coated with an adhesive.

The invention relates to a rope having a length LR of at least 100 m, the rope comprising synthetic filaments with a filament tenacity of at least 1.0 N/tex, characterized in that a weight fraction χ of the total weight of synthetic filaments present in the load bearing core have a length LF of 0.01 m to 0.7*L.sub.R, wherein said weight fraction is at least 50 wt %. The invention further relates to an airborne wind power generation system comprising the rope as well as the use of the rope in an airborne wind power generation system wherein the length of the rope oscillates between a maximum length L.sub.max and a minimum length L.sub.min, wherein L.sub.max is at most 10,000 m and L.sub.min is at least 100 m and wherein the ratio of L.sub.max to L.sub.min is between 10 and 1.5.

The invention relates to a rope made of textile fiber material, comprising a rope core and a sheath surrounding the rope core, wherein the sheath, an intermediate sheath located between the sheath and the rope core and/or a reinforcement located between the sheath and the rope core comprise(s) a twine of excess length, the twine of excess length being formed in that it comprises at least a first yarn and a second yarn which are twisted together, the first yarn having a greater length than the second yarn, measured in an untwisted state of a unit length of the twine. In a further aspect, the invention relates to a method of manufacturing a twine of excess length for the above-mentioned rope.

Methods and systems for braiding sutures and the resulting constructs are disclosed. The sutures can have alternating bifurcated and non-bifurcated lengths. The sutures can have looped-ends, with both ends of the loop having contiguous braiding with the adjacent body or remainder of the suture. Braiding machines can have one or more bifurcating bars that can controllably obstruct or allow passage of the shuttle and carriers of the braiding machine. The controllable bifurcating bars can result in u-turns in the shuttle and carrier paths, such as a path encircling a horngear adjacent to the bifurcating bar, or passage of the shuttle and carrier across the bifurcating bar.

The present invention relates to a mooring rope for use in subsea mooring, or a substantially synthetic rope thereof, said synthetic rope comprising a rope core and a layered shell arranged around the rope core, said the shell having a braided outer shell layer. The shell comprises sub-surface buoyancy elements, suitable for use in a subsea environment, extending in radial direction between the rope core and the outer shell.

A mixed rope used for oceanographic buoy mooring system, comprises mixed core rope of metal and fiber and cover rope, wherein, the mixed core rope of metal and fiber comprises metal coil spring and fiber supporting core inside the metal coil spring; the cover rope is woven of several number of twisted strand; the mass content of the mixed core rope of metal and fiber is not greater than 20% of the mass of mixed rope, the mass content of the cover rope is not less than 80% of the mass of the mixed rope. Mixed rope used for oceanographic mooring system disclosed in present embodiments has small linear density and high fracture strength, may be used as data communication channel from under-water sensor to the over-water receiver, being soft, light and easy to deploy, the mixed rope can be used as the upper part of the oceanographic buoy mooring system with prospective application.

The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume.
