A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

The present disclosure relates to a cable comprising a cable core and an armor, the armor being formed by a plurality of consecutive sections of non-metallic tensile elements wound around the cable core, each section including a first non-metallic tensile element connected to a second non-metallic tensile element of the consecutive sections by a joint comprising a first socket and a second socket, each of said sockets comprising a flat body extending longitudinally along a longitudinal axis (S) between a proximal end and a distal end and comprising an inner through bore between a proximal aperture at the proximal end and a distal aperture at the distal end, the first and second non-metallic tensile elements having an end portion being housed in the inner through bore of respectively the first and second socket by the proximal aperture and secured therein by a bonding material, and each inner through bore being shaped to translationally and rotationally lock the bonding material; an interconnecting device translationally and rotationally locked in the distal apertures of the first and the second sockets and allowing the sockets to relatively rotate exclusively around at least one rotation axis (R) perpendicular to a plane where the socket body longitudinal axes (S) of the first and the second sockets lie.

A novel cable construction provided an armored covering over a cable containing high-strength synthetic filaments. The synthetic cable is provided with a strong and tough termination where it attaches to the prior art dragline or power shovel digging equipment. An external armoring is then provided from the termination for a specified distance up the cable. The armoring ceases prior to the point where the cable passes over a pulley. At that point the cable just carries a conventional encapsulating jacket. A collar is preferably provided to seal the end of the armoring portion to the jacket.

A method for terminating a cable (6) having at least one strength member (7). The method includes the steps of providing a cable termination comprising at least one termination chamber (2) for accommodating an end section of the strength member (7) and arranging and fastening an anchoring sleeve (12) around at least parts of the end section. The method further includes introducing the end section into the termination chamber (2) and fastening the end section by curing a polymer resin in the termination chamber (2) as well as a termination suitable for the method.

A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a composite cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

A sucker rod terminus assembly is provided for use in downhole wells. The sucker rod terminus assembly includes a plurality of parallel composite strands forming an elongate rod and a metallic terminus fitting. The terminus fitting has a cavity with a proximal opening to receive the rod end. The cavity includes a plurality of frustum shaped chambers. Preferably, the frustum shaped chambers have different sizes or shapes wherein at least a frustum chamber's proximal end diameter, distal end diameter, or length is different than an adjacent frustum chamber's proximal end diameter, distal end diameter, or length. Even more preferably, each frustum chamber is diametrically larger than the frustum chamber positioned proximally to it. Preferably, the sucker rod assembly further includes a spreader plate, preferably made up of a plurality of pieces and a hardened material to affix the rod to the terminus fitting.

Various embodiments of the present disclosure provide a hollow-braided rope having a new and improved rope termination formed therein and a new and improved rope termination system for forming the rope termination. Generally, the rope termination of the present disclosure is formed using a double-braided portion of hollow-braided rope in conjunction with a set of mechanical components of the rope termination forming system. The use of both the double-braided portion of the hollow-braided rope and the set of mechanical components causes any applied tensile forces to be distributed between the double-braided portion and the mechanical components. The distribution of part of any applied tensile forces away from the mechanical components and to the double-braided portion of the hollow-braided rope itself enables the mechanical components to be relatively small and lightweight and reduces the size and weight of the rope termination without compromising strength.

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.

A coupler may be provided. The coupler may comprise a first cylindrical cavity, a first truncated conical cavity, and a second truncated conical cavity. The first truncated conical cavity may be adjacent to and concentric with the first cylindrical cavity. The first truncated conical cavity may have a first angle. The second truncated conical cavity may be adjacent to and concentric with the first truncated conical cavity. The second truncated conical cavity may have a second angle less than the first angle.

A synthetic rope arrangement is disclosed for use with a construction machine. The synthetic rope arrangement may have a synthetic rope with an end, and an anchor having an opening formed therein to receive the end of the synthetic rope. The anchor may be removably connectable to the construction machine. The synthetic rope arrangement may also have a stop coupled to the end of the synthetic rope and configured to inhibit the end of the synthetic rope from passing through the anchor.
