  • Patent number: 4965411
    Abstract: A splice for joining the armoring of two wire-armored cables (1, 2). The armoring is clamped between conical parts (5, 9; 6, 10) at each cable end. Each inner conical part (5, 6) is integral with a flange (7, 8) bolted to one of two similar flanges (13, 14) fixed to opposite ends of a generally tubular flexible assembly itself constituted by three layers of metal wires. The innermost first layer (22) is wound helically. The other two layers (19, 20) are wound with substantially equal and opposite pitches. The inside diameters of the first layer and of the circular openings in each of the two flanges (13, 14) fixed thereto are such that the flexible assembly is capable of sliding at one of its ends over at least one of the cables to be connected after its armoring layers have been removed, and at its other end over the splice (21) between the cables themselves. The invention also provides a method of making the splice.

  • Patent number: 4523724
    Abstract: A coiling-down tank (1) comprises a circular outer wall (3) delimiting a coiling-down zone, and cable (4) to be coiled down (e.g. heavy electric cable) is delivered to the machine (10) from a point (80) vertically above the center of the tank. The machine comprises an upper support bracket (70) mounted to rotate about the vertical axis of the tank, a sloping coiling-down arm (20) connected at its upper end to said bracket and supported at its lower end by running means disposed to run along the said wall (3) of the tank (1). The arm is fitted with a carriage (30) that is longitudinally displaceable along the arm, and an inlet chute (60) receives cable from the point (80). The inlet chute guides the cable into the carriage, and the lower end of the carriage serves to dispense the cable into the tank for coiling down.

  • Patent number: 4412878
    Abstract: A method of joining together optical fibre undersea cables. In a first step, a given length of a carrier vault (1, 2) which surrounds the optical-fibre containing core (3, 4) of the cable end is cut off so as to clear a sufficient length of optical fibre (5, 6), a part (9, 10) with at least one opening (11, 12) in which said optical fibre (5, 6) is inserted is placed in each said cable ends between the strands of the carrier vault, the ends of said carrier vaults (1, 2) are brought together and fixed substantially in contact each with another, said optical fibre ends (5, 6) of each of said cables are connected together then the excess length of fibre thus formed is stretched and helically wound around a sleeve (14).

  • Patent number: 4388800
    Abstract: An optical fibre cable comprises a support structure having helical grooves around its periphery. Optical fibres are laid in the grooves. Said fibre-containing grooves (2) are then partially untwisted in the direction of the arrow (4), thereby lengthening the pitch of the grooves and hence lengthening the fibres relative to the grooves.

  • Patent number: 4341440
    Abstract: An undersea optical fiber cable with a protective metal casing around the optical fibers 1. The casing includes a stranded assembly 3 of high-tensile metal wires of polygonal cross-section 3A forming an arch structure. The side (4) which is turned towards the axis of the cable is shorter than the outwardly-turned side 5, and intermediate sides 6 touch or interlock. A metal outer tube 7 is formed by skelping a tape to produce a cylinder and then welding the longitudinal edges thereof. The metal casing is filled with a liquid 4A whose density is close to that of water and whose viscosity is close to that of glycerine. The overall density of the cable is slightly higher than that of water.

  • Patent number: 4218417
    Abstract: The device includes a moving mould 2 which defines a cylindrical mould cavity 12 closed on one side and open on the other. The repair material 10 is brought through an annular orifice, the pressure of the material drives the slidable mould towards the right (closed side) and the hardening material completes the closing of the mould which, while moving, can cover any distance and the length of the packing to be effected is therefore not limited, while the volume of the tooling is small. A fixed sleeve 3 is used to prime the operation.
