An anti-rotational locking apparatus for locking an elongate rotatable element in a particular rotational position with respect to a housing include: a sleeve having an internal profile for slidably receiving therethrough a rotatable elongate element having a portion with an external profile configured to positively engage with the internal profile of the sleeve; a housing; and a locking pin. The sleeve has a flange with a first opening therein and the housing has a second opening therein, the locking pin being insertable in the openings. The flange is arranged for slidable alignment with the second opening in the housing such that when the openings are aligned, the locking pin may be inserted in the openings to lock the flange to the housing and thereby prevent rotation of the flange and of an elongate element extending therethrough and engaged therewith with respect to the housing.

Systems and methods of deploying seismic data acquisition units from a marine vessel are disclosed. The system can include a spindle coupled to a tether. A robotic arm can couple the spindle to a tether via one or more tumblers. The tether can connect to a seismic data acquisition unit via a connection block having a mechanical force device. The assembled spindle, tether and seismic data acquisition unit can be deployed from the deck via a deployment block.

A device and method for holding an electrical cord, such as a cellular phone charging cord, so that the electrical cord is easily restrained, located and retrieved. The device may be constructed of a flexible body that may be in any desirable shape. The body is provided with a slit that extends some distance, and in some embodiments, approximately halfway through the body. An electrical cord can be inserted through the slit. At the center of the body, the slit is enlarged to form a channel for receiving the cord. With the cord thus secured within the channel, the body makes the cord easier to find and less likely to slip or fall off of a surface where the cord is to be placed.

A cable securing device facilitates secure connection to a cabling end, and employs a retaining cap, a barrel and a cable receiving component.

A connector (10) is provided. The connector (10) is for connecting to a downhole longitudinal member (12). The connector (10) comprises a gripping sleeve (14) defining an internal bore (16) for receiving the longitudinal member (12) therewithin, wherein the gripping sleeve (14) is configured to grip or to increase grip on the longitudinal member (12) by lengthening the gripping sleeve (14). Also provided area system in which the connector (10) is used, and a method of connecting a connector (10) to a downhole longitudinal member (12).

A system for tensioning a rope of a play structure includes a collar coupled to the play structure. The system includes a tensioner coupled to the rope. The tensioner is coupled to the collar through a threaded connection and where a rotation of the tensioner in relation to the collar adjusts a tension in the rope.

In accordance with one aspect of the present disclosure, a fastener is provided for securing to an end of a conveyor belt having cables. The fastener comprises a crimp configured to be fixed to a conveyor belt cable and a connector. The connector has a unitary, one-piece fastener body with an upper portion for being disposed adjacent an upper surface of the conveyor belt end and a lower portion for being disposed adjacent a lower surface of the conveyor belt end. The upper and lower portions are spaced apart to receive the crimp therebetween and permit the conveyor belt cable to extend in an outboard direction between the upper and lower portions. The connector includes a stop arranged to block inboard movement of the crimp and the conveyor belt cable fixed thereto.
