The structure (34, 134) of the cable (20, 120) retains conductivity upon stretching of the jacket layer (52) surrounding the structure (34, 134) that lengthens the cable (20, 120). For one embodiment of the method a conductor (20) wrapped around a rod (24) and enclosed within a sheath layer (32) forms the structure (34, 134). For another embodiment of the method a braided conductor (122) enclosed within a braided sheath (124) and a polymeric layer (132) forms the structure (34, 134).
Disclosed is a tow warp construction and a process for forming such tow warp construction where such tow warp construction has a longer life span, that is retains its useful dimensions and characteristics longer than known tow warp constructions and consequently has a longer useful life span than known tow warp constructions. Most broadly the construction of the tow warp construction of the present disclosure and process for forming such includes gradually and progressively introducing fibers from a second group of fibers (or “second group of linear elements”) into an otherwise conventional stranding process where fibers from a first group of fibers (or “first group of linear elements”) are being stranded to form strands (or “third group of linear elements”), so as to either or both increase the diameter of the strands and/or substitute the first group of fibers by fibers from the second group of fibers, so as to: a) in the first instance, increase the diameter of the formed strands and subsequently of a strength member formed of the strands, especially for increasing the diameter and strength of the tow warp's strength member in and about the splice braid zone where it connects to a towed object such as a paravane; and b) in the second instance, substitute in a predetermined region on the long dimension of the strands and subsequently in a predetermined region on a long dimension of a strength member formed of the strands fibers of higher creep and/or lower melting points by fibers of lower creep and/or higher melting points, especially for increasing the resistance of the tow warps strength member to bending fatigue.

Producing the headline sonar cable (20, 120) is characterized by the steps of: a. providing an elongatable internally-located conductive structure (34, 134) that is adapted for data signal transmission; and b. braiding a strength-member jacket layer (52) of polymeric material around the structure (34, 134) while ensuring that the structure (34, 134) is slack when surrounded by the jacket layer (52).
An improved trawl door (10) is adapted for being towed through water both at shallower and at larger angles of attack. The trawl door (10) includes at least one main deflector (24, 25) having a profile (46) formed by an inner surface (48) and an outer surface (47). The profile (46) spans a chord length 'C' that extends along a Chord Direction Line (83) between leading and trailing edges (12, 14) of the main deflector (24, 25). The trawl door also includes at least one leading edge slat (20, 22) at least a portion of which is located in front of the outer surface (47) of the main deflector. The trawl door (10) in one aspect is characterized by an acute angle of inclination (91, 92) between a chord line (81, 82) of the leading edge slat (20, 22) and the Chord Direction Line (83) that is at least thirty-five degrees (35°). The trawl door (10) in another aspect is characterized by having an aspect ratio of at least two to one (2.0 : 1.0).
A trawl door (20, 60) or a paravane (120, 140) having at least one main deflector (22, 22U, 22L) includes a permeable structure disposed adjacent to and separated from an outer surface (34) of the main deflector (22, 22U, 22L).
