Abstract: An affordable tension device for maintaining tension on a wire rope of a cable-based lifting system is provided. The tension device has an elongated casting weight adapted to govern the casting weight as it rides along a predetermined wire rope for maintaining tension thereon. The tension device provides a clevis with a sheave for operatively associating with the tension wire rope.

Abstract: A removable rack pulley system is provided. The removable rack pulley system is detachably connected to a rack and is employed to adjust cables that are associated with equipment stored in shelves of the rack. The rack pulley system includes a cable-run assembly and a locking mechanism. The locking mechanism includes a pressure-actuated locking pin to adhere and release calipers that attach the rack pulley system to the rack. The cable-run assembly uses a multi-length shaft that is integrally connected to the locking mechanism. The multi-length shaft is configured to receive multiple spools of cable to allow various types and sizes of cables to be simultaneously pulled through the rack pulley system while retaining separation of the cables during adjustment of cables. The spools are secured in the cable-run assembly by a holding wire that detachably connects to an end of the multi-length shaft.

Abstract: A wire guide module for guiding and changing the direction of wire in a wire dispensing system. The wire guide module having an inner passageway with rollers. The rollers adjacent the inner passageway assist the wire in moving smoothly through the wire guide module as the shape of the inner passageway changing the direction of movement of the wire. A wire dispensing system having wire guide modules with rollers which change the direction of the wire while reducing damage to the wire.

Abstract: The traction system comprises a plurality of substantially parallel tendons (2) movable for pulling a load, the tendons being disposed according to a pattern in a plane perpendicular to the tendons; and at least one deviator (3) for guiding the tendons, the deviator accommodating an angular deflection of the plurality of tendons. The deviator includes a support structure (4) and a plurality of segments (5) each having an inner surface facing a convex surface of the support structure, front and rear surfaces and a plurality of channels extending from the front surface to the rear surface. The channels are disposed according to said pattern in the front and rear surfaces of each segment, each tendon being received in a respective one of the channels. At least some of the segments (5) have their inner surfaces bearing on the convex surface of the support structure (4) in response to tensile forces applied to the tendons.

Abstract: A removably-positionable ratline for modern sailboats comprising an adjustable belt and two shroud vice clamps with a base member and a jaw comprising mating faces with arcs that, when aligned with one another, allow a fastener to be engaged through them so as to hold both components together and form a central opening to grip a shroud cable.

Abstract: A system for adjusting spreaders and diamonds on sailing boats, the system being adapted to provide spreaders or diamonds which are adjustable on the water thus allowing the craft's crew greater control of the sailing rig. The system has a pair of spreader arms pivotally connected to a pair of control arms attached to a mast. The spreader arms are adjustable by means of a halyard which runs via the control arms to distal ends of the spreader arms. The spreader arms have a number or holes or slots proximate their distal ends to receive respective port and starboard stays of the sailing craft. Depending on prevailing wind conditions, the spreader arms may be selectively pivoted forward towards the control arms by a pulling force applied to the halyard. In this way, the shape and bend characteristics of the mast may be altered by the crew so as to control the amount of draft in the sails and to affect the amount of power generated by the sailing rig.

Abstract: Surf board has multiple functions to serve as the sail boat, surf board, wind surf board, canoe and the rest seat on water. It comprises a foldable revolving sail, water wings, single sided pedals, water turbine, water jet nozzle, the foldable reclining seat and board with removable canoe cover. The revolving sail drives the horizontal water turbine to generate the water jet. The water jet may swivel to propel the surf board in different direction. The revolving sail also serves as the sunshade umbrella. The foldable revolving sail adopts the flexible parafoil sail. If the wind is weak, the rider steps on the single sided pedals to rotate the water turbine to propel the board. Furthermore, the revolving sail and water wings lift the board to glide in the air and land softly.

Abstract: A mast collar system for securement to a surface at the location where the mast extends down through the surface includes a rigid collar which loosely encircles the mast. Positioned in the gap between the mast and the collar is a resilient ring. An annular groove extends down into the ring and a spline is pressed down into the groove so that a fluid-tight gasket is formed between the mast and the collar. The ring or spline also includes a fin which resiliently engages the mast directly above the annular line of sealing engagement between the mast and the ring per se.

Abstract: The subject of the invention is a sheet cleat, especially for sailboats, whose essential elements are movable gripping jaws which form a gripping gap between them, and whose surface parts cooperating with the sheet consist of rollers having a serration and having a rotation-symmetrical envelope surface. The rollers are freely rotatable about axes which are parallel to the plane of movement of the gripping jaws. The sheet is pressed into the gripping gap with rotation and spreading apart of the rollers, and there it is held fast positively and frictionally, but is easily releasable. In the direction of the tension on the sheet under the usual stress, a locking action takes place; in the opposite direction the sheet can be easily retightened. Reduction of wear and tear on the sheet is the additional effect. A plurality of roller pairs can also be present. An adjustable bearing surface and a likewise adjustable guiding means are provided for the sheet as possible accessory devices.

Abstract: A jib sheet apparatus for sailboats which will permit a jib sheet, and thus a head sail of any size, to be trimmed from one side of a sailboat to the other, as in tacking or jibbing, by use of a continuous, closed traveller-track and fairlead apparatus system which requires simply a single, unskilled crewperson of but average strength and manual dexterity to operate, and which can be operated from a single position in the cockpit with minimum effort, or in an alternative mode, by electricity.
