UNIT FOR PRODUCING AN ASSEMBLY
An apparatus for producing an assembly of filamentary elements that are wound together in a helix includes a twisting device, a preforming device, and an assembling device. The twisting device is structured to twist at least first and second filamentary elements individually, such that each filamentary element is twisted separately from another filamentary element, to produce at least first and second twisted filamentary elements. The preforming device, which is arranged downstream of the twisting device, is structured to preform each of the twisted filamentary elements individually into separate preformed helixes, to produce at least first and second preformed helixes. The assembling device, which is arranged downstream of the preforming device, is structured to assemble the preformed helixes into an assembly.
Hybrid rope
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.

METHOD FOR FABRICATING STEEL WIRE CABLE COMPRISING ZINC- ALUMINIUM ALLOY PLATING
A method for fabricating a steel wire cable having a ZnAl alloy plating, the method including: arranging steel wires according to an arrangement rule at a cross section of the steel wire cable; controlling a length of the overall cable by a length of a central standard wire; twisting a bunch of the steel wires comprising a zinc-aluminum alloy plating with a torsion angle of between 2 and 4; wrapping the steel wire bunch with a polyester wrapping bandage and covering a resulting product with a double-layered protective polyethylene sheath; anchoring the two ends of the steel wire cable by anchors using fillers; and coiling the finished-product of the steel wire cables.
CABLE STRANDING APPARATUS EMPLOYING A HOLLOW-SHAFT GUIDE MEMBER DRIVER
A cable-stranding apparatus includes a stationary guide, a motor, a driven guide, and a controller electrically coupled to the motor. The stationary guide is configured to guide strand elements in a spaced-apart configuration and to pass a core member. The motor is operatively associated with a guide driver. The driven guide is disposed at least partially within the guide driver so as to rotate therewith. The driven guide is configured to receive the strand elements from the stationary guide, individually guide the strand elements received from the stationary guide, and to further pass the core member. The controller is electrically coupled to the motor and configured to control the rotational speed and direction of the motor.
METHOD OF SZ STRANDING FLEXIBLE MICROMODULES
The invention concerns a method of SZ stranding into one strand a bundle of two or more flexible micromodules, each micromodule comprising one or more optical fibers. A first pulley is located with its winding surface adjacent to a longitudinal axis of a cabling line. The bundle of micromodules is guided over the winding surface of the first pulley, the first pulley being rotating around the longitudinal axis of the cabling line. The rotational speed, or the rotational direction of the first pulley, is alternating.
Method for producing an underwater pipe
A method for producing a tubular underwater pipe including: assembling a structure of peripheral metal elements (3A, 3B, 3C) wound in an S-Z configuration about a central flexible core (1) as the core is driven in movement along its longitudinal axis; providing an inductive sensor (12) arranged for rotation about the central flexible core (1) in a manner synchronized with the longitudinal movement of the core so that the sensor scans the periphery of the structure opposite and in the immediate proximity of peripheral elements wound about the core and during the assembly step; using the sensor (12) to acquire measurement signals (S) of which the amplitude varies according to whether or not the sensor (12) is located opposite a peripheral element during the rotation of the sensor (12); and using the measurement signals to control the positioning of the assembled peripheral elements.
Reinforced adhesive complex coacervates and methods of making and using thereof
Described herein is the synthesis of reinforced adhesive complex coacervates and their use thereof. The reinforced adhesive complex coacervates are composed of (a) at least one polycation, (b) at least one polyanion, and (c) a reinforcing component. The adhesive complex coacervates described herein can be subsequently cured to produce strong, cohesive adhesives. The reinforced adhesive complex coacervates have several desirable features when compared to conventional adhesives. The reinforced adhesive complex coacervates are effective in wet or underwater applications. The reinforced adhesive complex coacervates described herein, being phase separated from water, can be applied underwater without dissolving or dispersing into the water. The reinforced adhesive complex coacervates have numerous biological applications as bioadhesives and bioactive delivery devices. In particular, the reinforced adhesive complex coacervates described herein are particularly useful in underwater applications and situations where water is present such as, for example, wet tissues in physiological conditions.
TENSIONING APPARATUS FOR SYNTHETIC SLING MANUFACTURING APPARATUS AND METHOD
A sling manufacturing apparatus for constructing a synthetic sling having a cover and a core, includes a frame defining a longitudinal frame axis, a yarn feeder assembly associated with the frame, a drive roller connected to the frame, a tailstock movably mounted to the frame, an idler roller movably mounted to the tailstock, and an idler actuator secured to the tailstock. The drive roller is drivable to draw yarn from the yarn feeder assembly and the tailstock is movable relative to the frame substantially parallel to the longitudinal frame axis. The idler roller is movable relative to the tailstock parallel to the longitudinal frame axis. The idler actuator is configured to move the idler roller from a loading position spaced a first distance from the tailstock to a tensioned position spaced a second distance from the tailstock, wherein the first distance is greater than the second distance.
Hybrid rope or hybrid strand
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
