A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

A cable bending limiting arrangement is provided for an anchoring unit including an anchorage, a cable including a plurality of wires and/or strands extending in a tensioned manner from the anchorage, a compacting clamp unit adapted for compacting the wires and/or strands to a side-by-side arrangement and located at a predetermined distance from the anchorage, and a recess pipe surrounding the cable in at least a portion of the predetermined distance. The cable bending limiting arrangement includes a cable bending limiting device adapted for being located axially inside the recess pipe and radially between an outer surface of the cable and an inner surface of the recess pipe leaving an annular gap of a predetermined radial width if the longitudinal axis of the cable extends substantially parallel to the longitudinal axis of the anchorage.

A fastener that holds two portions of a cord-like material, which has ends, in a temporarily locked position until a prescribed force is applied to these ends to cause the material to slide though the fastener, includes (a) a rear enclosure having a cavity with two holes and two openings that each have a centerline, (b) a front enclosure having two apertures, each with a centerline, (c) a pair of movable posts, each having a centerline, and wherein the enclosures and posts are configured so that their respective centerlines can temporarily be brought into alignment so as to allow an end of the material to pass through the fastener, and (d) a pair of springs, each in contact with the bottom of a post. Wherein, the spring has a spring constant (k) and the post has a coefficient of friction (c.sub.f) with respect to the material, and k and c.sub.f are chosen to yield a prescribed force in the range of 2 to 25 pounds.

In an example, a lacing engine apparatus can include a housing and a drivetrain. The housing can be securable within a footwear article. The drivetrain can include a motor, a sun gear, a planet gear, a rotating ring gear, and a spool. The spool can be secured to the ring gear and can be rotatable therewith. The spool can be configured to control a lace of the footwear article and can be configured to wind the lace as the ring gear rotates in a first direction.

An article of footwear, lacing engine, and method includes a motor, a transmission operatively coupled to the motor, and a lace spool. The lace spool is operatively coupled to the transmission and includes a top lace groove in a top surface of the lace spool and a circumferential channel, wherein the lace is configured to be inserted in the top lace groove and be taken up around the circumferential channel based on a turning of the lace spool from action by the motor and transmission. A fastener is configured to couple the lace spool to the transmission and is inserted into the lace spool via the top surface, the fastener having a head having a head width sufficient to partially cover the top lace groove, leaving a top gap having a gap width less than a thickness of the lace.

A hoisting system for hoisting a load includes: i) a main winch system having a main rope with an end connector mounted to an end of the main rope, ii) an auxiliary winch system having an auxiliary rope having at least one rope connector of which at least one is a splitable rope connector, the auxiliary rope comprising a first section and a second section connected to the first section via the splitable rope connector, wherein the splitable rope connector comprises at least two connector parts that are releasably connected with each other for allowing quick disconnection and reconnection between the second section and the first section, wherein the connector parts (are configured for releasably connecting with the end connector of the main rope, and iii) a hang-off point placed and configured for at least temporarily holding a respective rope connector of the auxiliary rope for transferring the load to the hang-off point. The system may include two auxiliary winch systems.

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 to 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.
