A power cleat system having a cleat assembly, a cleat base assembly, a backer plate assembly, a cylinder assembly, and a guide support assembly. The cleat assembly has a top end, a base, and guide shafts. The cleat base assembly has a drain groove, a base, threaded sections protruding from the base, and linear bearings. The backer plate assembly has a backer plate, backer plate holes, and a backer plate housing hole. The cylinder assembly has a cylinder, exterior and interior threading, a fitting, a spring, a piston, a piston rod, a piston cylinder cap, and a piston screw. The guide support assembly has mounting flanges, a base with a hole, and a base screw. The power cleat system further has a bezel gasket assembly, and an electrical assembly that has a light source to illuminate the cleat assembly and/or the cleat base assembly.

A hand-held rope tie is operable to releasably hold two side-by-side portions of a rope. Pivotally connected arm members accommodate and hold the rope portions with a selected clamping pressure. The clamping pressure can be adjusted to create drag or resistance on the rope pulled through the arm members during horse pull-backs to relieve horse panic. Rope tie is also adjustable to tightly grip the rope without slippage of the rope through the arms when desired.

An unmanned seismic vessel system can include a hull system configured to provide buoyancy and a storage apparatus configured for storing one or more seismic nodes, each seismic node having at least one seismic sensor configured to acquire seismic data. A deployment system can be configured for deploying the seismic nodes from the storage apparatus to the water column, where the seismic data are responsive to a seismic wavefield, with a controller configured to operate the deployment system so that the seismic nodes are automatically deployed in a seismic array.

The present invention provides a device (1) for locking and unlocking an elongate tubular element (2), the device comprising: a. A braided or knitted tubular locking sleeve (3) that has a first end (3a) and a second end (3b), and that has an inlet orifice (4) for allowing said elongate tubular element (2) into it, and an outlet orifice (5) for allowing said elongate tubular element (2) out of it; b. Fastener means (6) for fastening said locking sleeve (3) to a support (7); and c. Tensioner means (8) for tensioning said locking sleeve (3) along a substantially rectilinear path (L) making it possible to lock said elongate tubular element (2) inside said locking sleeve (3) between said inlet orifice (4) and said outlet orifice (5), said tensioner means (8) being deactivatable manually, and/or by using deactivation means (9), for unlocking said elongate tubular element (2) to enable it to slide inside the internal volume of the locking sleeve (3) and through said inlet orifice (4) and said outlet orifice (5).
