Ribbon termination member

Claim 2

A strength member arrangement for a towed sonar array comprising: an elongated flexible strength member extending within and along the length of a sonar array module for carrying the tensile load of said module from one end thereof to the other, the ends of said elongated flexible strength member being joined together to form one continuous loop comprising a first end disposed towards one end of said module, and a second end disposed towards said other end of the module, ; and rigid termination members coupled to each end of said loop.

Claim 3

The strength member arrangement of claim 1 in which the ends of said elongated flexible strength member are joined together by splicing.

Claim 4

The strength member arrangement of claim 2 in which said flexible strength member is looped around smooth, large diameter pin-surfaces provided in said rigid terminations.

Claim 5

The strength member arrangement of claim 3 in which said flexible strength member forms a double loop passing through inner and outer pin-surfaces provided in said rigid terminations.

Claim 6

The strength member arrangement of claim 4 in which said flexible strength member forms a double loop defining four flat ribbon legs, and means provided to space said legs apart and in an orthogonal relationship to each other.

Claim 7

The strength member arrangement of claim 5 in which said elongated flexible strength member is made of a synthetic aramid fiber.

Claim 8

The strength member arrangement of claim 6 in which said rigid termination is made of titanium.

Claim 9

A termination member to receive a ribbon in tension and transfer the tension load on the ribbon to the strength member, said strength member comprising; tensile connection means on said body for connecting said body to provide tensile stress on said body; first and second side legs on said body, said side legs being spaced from each other, the outer surface of said said body and the outer surface of said side legs being shaped to fit within a cylindrically tubular opening; first and second cross pins extending between said side legs, first and second cross pins having both having curved surfaces thereon facing said tension means on said body, at least a portion of said curved surfaces on first and second cross pins each being curved about a separate axis, said axis substantially lying in the same plane, said first pin being closer to said tension means and having a curved surface thereon which extends around said axis substantially 180 degrees and said second pin having a curved surface thereon about said axis which extends for more than 180 degrees so that when a tension ribbon is engaged upon said first and second pins, the ribbon on said second pin engages the same radius even when it is not pulling directly in alignment.

Claim 10

A termination member to receive a ribbon in tension and transfer the tension load on the ribbon to the strength member, said strength member comprising; tensile connection means on said body for connecting said body to provide tensile stress on said body; first and second side legs on said body, said side legs being spaced from each other, the outer surface of said said body and the outer surface of said side legs being shaped to fit within a cylindrically tubular opening; first and second cross pins extending between said side legs, first and second cross pins having both having curved surfaces thereon facing said tension means on said body, at least a portion of said curved surfaces on first and second cross pins each being curved about a separate axis, said axis substantially lying in the same plane, said first pin being closer to said tension means and having a curved surface thereon which extends around said axis substantially 180 degrees and said second pin having a curved surface thereon about said axis which extends for more than 180 degrees so that when a tension ribbon is engaged upon said first and second pins, the ribbon on said second pin engages the same radius even when it is not pulling directly in alignment.

Claim 11

The member of claim 8 wherein the outer surface of said body and said outer surface of said legs are concentric about a body axis and said body axis lies in said plane.

Claim 12

The member of claim 9 wherein said curved surface of second pin on the side of said axis of curvature of said second pin away from said tension means extends outward beyond the inner surface of said legs so that said curved surface lies on the ends of said legs.

Claim 13

The member of claim 8 wherein said curved surface of second pin on the side of said axis of curvature of said second pin away from said tension means extends outward beyond the inner surface of said legs so that said curved surface lies on the ends of said legs.

Claim 14

The member of claim 10 wherein said curved surfaces of said first and second pins are both right circular cylindrical surfaces and said surfaces have the same radi.

Claim 15

The member of claim 12 wherein said curved surfaces of said first and second pins have a diameter equal to the thickness of said legs in the diametrical direction of said first pin.

Claim 16

The member of claim 13 wherein said tension means is threaded for connection of said member to another similar member.
