The look Each arm is supported by at least one cross-arm, which rides on wheels for a land site, or on at least one double-ended float for water sites. Arm A is supported by at least one cross-arm CA and float F per arm A, as in FIGS. The radius of arm A from load LD to cross-arm CA need not be equal to the radius of arm A from load LD to pivot point O for beam BM. 13, showing a rigging modification applicable not only to the embodiment of FIG. Since anchor cables ANC and optional underwater vanes UV prevent rotation of buoy BU, a load output cable (not shown) from load LD to load output destination may then be direct, with no slip ring mechanism required on the bottom.

abstract colorful background 1-4 indicates the position of this optional control mechanism for disabling operation of the SDWM during periods of high wind. 8-10 could be used to disable operation of the sailboat during high wind, by applying the beam line BL, beam pulley BP, and beam spring BSP combination in FIG. The bearing unit must be sealed as well as possible to keep out water (especially salt water–this mechanism may also be used for the shallow and deep water sites which are disclosed with regard to FIGS. 1, as modified for use on water as disclosed with reference to FIGS. FIG. 18 is a fragmentary schematic top plan view of an arm of the modified device of FIG. Because it can be modified to some extent without departing from the principles thereof as they have been outlined and explained in this specification, the present invention should be understood as encompassing all such modifications as are within the spirit and scope of the following claims.

Any of the features which have been described above with reference to any of FIGS. 18-20. Dolor de espalda despues de la epidural . The remainder of the structure of this embodiment may be as has been described above with reference to FIGS. 21 may be as has been described above in regard to any of FIGS. In FIG. 16, a double-ended SDWM is shown, one which is similar in all respects to the embodiment which has been described above with respect to FIGS. 12, for all three types of sites, or at least the land and shallow water sites. For all three types of sites, the sail drag must be transferred to the ground, while the sail lift must be transferred to the load via the arm. Of course, the land-based embodiments described above will be provided with arm support means appropriate for supporting the arm or arms from the ground, e.g.

Then a load support required for a deep water site (FIG. In FIG. 21, a load support for a deep water site is shown. SDWMs for three types of sites are described: land, shallow water, and deep water. The simplest SDWM will be described first, with one arm, one cross-arm, one beam, one mast, and one sail, for a land site. If neither mechanism described above in relation to FIGS.

FIGS. 1-12 variations are described. FIGS. 22-24 show an apparatus similar to FIG. An economic analysis will probably show that a configuration with two arms is more economically feasible (lower cost per unit of power produced) than the similar configuration with one arm, and that increasing the number of sails per arm increase the economic feasibility. A probably worst case start-up situation from a `no wind` condition for a double-ended SDWM would be wind from a direction perpendicular to arm A. Fajas para aliviar el dolor de espalda . In that case, any imbalance of sail drag moments about load LD would cause the apparatus to rotate about load LD.

For the configuration with two masts M per beam BM, masts M are located on beam BM such that moments of drag of sails S about pivot point O approximately balance when wind W engages sails S. One mast M is mounted near the end of beam BM that is constrained to remain upwind of pivot point O. The other mast M is mounted on the other end of beam BM, nearer to pivot point O than the upwind mast M. Since drag moments of sails S about pivot point O approximately balance, a much smaller and less costly control mechanism for positioning beam BM (i.e. S. Moments of lift of sails S about load LD are additive. Then a double-ended SDWM for a land site will be described, with two arms, two cross-arms per arm, two beams per arm, and two masts and sails per beam (FIG. Sail S then drives arm A in the opposite direction across wind W and the cycle repeats.

11 and 12 for transferring sail drag to ground is used or is insufficient, then circular track TR (FIG. Spring-driven windup reels WR or beam windup reels BWR could be used in lieu of coil spings SP and BSP, as shown in FIGS. 10 to be positioned at point D. Alternatively, a beam windup reel BWR could be used in lieu of beam spring BSP, e.g. 15. Dolor al estirar la pierna detras de la rodilla . Beam pulley BP1 is attached to the end of beam spring BSP, and beam pulley BP2 is attached to arm A. Beam pulley BP3 serves the same function as beam pulley BP in FIGS. Any wind exceeding the threshold velocity would cause an angular disposition of beam BM relative to arm A about pivot point O which increases with wind velocity, up to some angle limited by stretching of beam spring BSP. The rotor is mounted for rotation relative to the stator about the axis of the drive shaft DS.

A bearing mechanism surrounds drive shaft DS, consisting of rotating bearing ring housing RB riding inside of fixed bearing ring housing FB. When wind W engages sail S, spring SP applies tension on line L, holding boom B in position to cause sail S to sail crosswind, which transmits energy extracted from wind W to load LD by rotating arm A about load LD. In this condition, spring SP applies sufficient tension on line L to return boom B to a position parallel to beam BM, and beam spring BSP applies sufficient tension on beam line BL to return beam BM to a position parallel to arm A. Spring SP and beam spring BSP must supply sufficient tension to lines L and BL, respectively, in the `no wind` condition to prevent slack, which could cause the lines to foul the pulleys. LS and LR are, respectively, the stator and rotor of a load.

Load stator LS rests on structure STR, which rests on the bottom. The structure at the upper end of FIGS. At the radially outer end of the arm A, a beam BM is shown pivotally mounted to the arm at pivot point O intermediate the ends of the beam BM, for pivoting about a generally vertical axis. CA which is mounted to the arm A so as to extend generally horizontally-transversally (tangentially). 11. Load stator LS is mounted in buoy BU, which is moored to ground by at least two anchor cables ANC. This mechanism transfers the static load of the upwind end of arm A to ground via load stator LS, transfers the sail drag load from arm A to ground via load stator LS, and transfers the sail torque from arm A to load rotor LR.

1, the bow of a conventional fore-and-aft-rigged sailboat SB could be connected to the downwind end of arm A by a flexible connection FC such as a chain, as shown in FIGS. Drive a three-phase AC generator, the output of which could be rectified (and filtered if necessary) to drive a DC load, such as a rechargeable battery. Load LD is fixed in buoy BU with a waterproof cover and a water-tight drive shaft DS. 21. Buoy BU may also be fitted with underwater vertical vanes UV to decrease rotation. The bearings between FB and RB may be either ball- or roller-type, and tilted if required to minimize wear. Cam CM is biased by weight WT bearing against cam frame CF and/or cam spring CSP to keep the space between cam CM and anvil ANV open during low wind conditions. 8-10 for preventing the above-described sailing operation during periods of excessive wind velocity.
