Abstract:
A lace line for forming structures including netting, such as codends, trawl nets, seines and fish pens, The lace line includes at least several distinct loop tails that are interlaced and/or interconnected with one another so as to form several lacing loops, In other aspects, the present disclosure teaches a codend including at least four hung-in riblines having at least four netting panels formed mainly and preferably entirely of T90 mesh, where the T90 mesh mainly and preferably entirely includes a mesh size of between one hundred sixty and one hundred ninety five millimeters, in combination with a hang percentage of between ten and twenty four percent.
Abstract:
Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope that has greater resilience to high heat temperatures resultant of use with powered blocks and/or sheaves and has a longer service life in comparison to known synthetic rope constructions. The rope of the present disclosure has multiple distinct synthetic substances each forming distinct components that work together to, surprisingly, increase tolerance to bending fatigue of the rope and especially to high heat temperatures resultant of use with powered blocks and/or sheaves in comparison to known synthetic ropes.
Abstract:
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.
Abstract:
Disclosed is a blended rope having an outer sheath (8) enclosing at least a strength member (7), the strength member (7) having high-strength synthetic fibers, the strength member (7) being a blended strength member (7) formed with a combination of ARAMID fibers and HMPE fibers, the blended strength member comprising a non-homogeneous distribution of the ARAMID and HMPE fibers, wherein the weight ratio of ARAMID to HMPE in the strength member (7) is preferably a minimum of 80:20.

Abstract:
Disclosed is a non-steel headline sonar cable having a strength member [5] and a core [1], the headline sonar cable comprising a length of a core-cable [10], the length of core-cable (10] comprising core [1] as well as comprising at least one fiber-optic conductor [2] that is: [i] disposed in a helical shape; and [ii] completely encased in a solid, flexible material. Also disclosed is a process for making a headline sonar cable. The headline sonar cable is capable of being wound on a winch under tensions and surging shocks experienced by a fishing trawler and provides high quality data signal transmission and resolution so as to permit use for transmitting data from high resolution sonars used to monitor fish caught in a fish trawl during operation.
Abstract:
A production method for a headline sonar cable characterized by steps of: a. providing a first strength member (14); b. coupling to strength member (14) a conductor (122); c. forming a layer of polymeric material about the combination of strength member (14) and conductor (122) while ensuring that the conductor remains slack; d. forming a flow shield around the layer of polymeric material, thus forming an elongatable internally located conductive structure; and e. braiding a strength-member jacket layer (52) of polymeric material around the elongatable internally located conductive structure while ensuring that the conductor is slack when surrounded by the jacket layer (52). For another embodiment, an optical fibre is wrapped around the exterior of the layer of polymeric material within which is enclosed a braided conductor formed about the first strength member (14). Other embodiments employ further thermo-plastic layers and further sheaths and further conductors.
Abstract:
A signal buoy (1) for retrieval of submerged objects, the signal buoy line's cross section has an aspect ratio greater than two and two tenths to one and preferably greater than four to one. In some aspect the signal buoy line includes conductors so as to permit communicating with submerged objects. In other aspects, the present disclosure teaches a combination of a signal buoy and a buoyant fiber mooring rope storage structure for storing submerged in a body of water and above a seabed or other bottom of the body of water a fiber mooring rope for future retrieval.

Abstract:
A rope has a braided sheath that includes a spiraling strand having a greater pitch in comparison with a pitch exhibited by other strands of a coverbraid that encloses that rope's strength member core. The rope is useful for forming pelagic trawl mesh, and is stronger for a given amount of material, has less drag, and exhibits the same or bettered lift when towed through water at trawl mesh angles of attack. The rope also is less costly to manufacture in comparison to known helix rope costructions.
