4) similar to the vertically disposed hydraulic cylinder 46, is so disposed for being pumped in response to the tilting movements of the cylinder. Because the column tilting can occur in any direction, the cylinder 46a is mounted for accommodating such movements. In Fig. 2, a tank 80 is shown (one half thereof being cut away for illustrative purposes) at the top of the tube 10, and an in-line series of separate tanks 82 are shown surrounding the column 24 inside the tube 10. A purpose of buoyancy tanks 80 and 82 is that, when surface storms are excessively severe, the buoyancy tanks are flooded to cause sinking of the tube and the float. 2, the securing ring 38 and the bearing 34 are shown broken away with only a single spoke 36 being shown. According to another aspect of the invention, there is provided an apparatus for use in a body of water for capturing energy from surface waves on said water body within a range of amplitudes up to a preselected maximum amplitude, the apparatus comprising a first member being reciprocally movable as a function of and in response to overpassing waves, relative to a second member and along a path the length of which is a function of the amplitudes of said overpassing waves; and said second member including buoyancy varying means for decreasing the buoyancy of said second member for causing said second member to tilt away from the vertical in response to the overpassage of surface waves having a preselected amplitude in excess of said preselected maximum amplitude and including a base member for anchoring the apparatus to the floor of the body of water, and said second member being pivotally mounted on said base member for allowing said second member to extend vertically upward from said base member when said second member is positively buoyant, and for allowing tilting of said second member when said second member is negatively buoyant.
In a preferred embodiment of the invention, an elongated, neutrally or slightly buoyant member is disposed in generally upright orientation at a selected depth beneath the mean water level of a body of water. During operation, pressure variations between the top and bottom ends of the vertically elongated, submerged member caused by over-passing surface waves cause relative movements of a piston (e.g., the member itself or a piston disposed within a hollow space within the member) for driving an energy converting transducer. The tube movement relative to the fixed float is the mechanism for converting wave energy (the force driving the tube) to useful energy. How the vertical oscillations are converted to useful energy is now described. Como quitar dolor de hombro . While energy is thus lost in the buffering system, damage to the system is avoided and, most importantly, energy is still being provided by the system.
With still further larger waves, the pressure relief valves pop open for reducing pressure differentials driving the tube 10. Eventually, should the wave energy become so great that the energy dissipation means are no longer adequate to protect the system, water ballast is taken into the buoyancy tanks for submerging the tube to a depth safely below the surface waves. With excessively high waves, the pressure differentials can drive the tube 10 with such high forces as to damage the system. An advantage of the system herein used is that it is based upon the use of buffer elements, e.g., the elastic blocks 66 which are commercially available in a wide range of sizes and with known stress-strain characteristics and which have been specifically developed for similar energy absorbing functions. When the pressure differential, either plus or minus, between the water within the tube 10 and the surrounding water exceeds, across the top closed end of the tube 10, a pre-selected level, the respective spring biased flaps are forced open for immediately reducing the pressure differential and thus immediately reducing the otherwise excessive forces of acceleration on the tube 10. Pressure relief means, e.g., spring poppet valves and the like, are well known.

Although movements of the skid base can occur, as described, the water above and beneath the anchor base tends to buffer movements thereof for partially reducing excessive acceleration and shocks. The anchor base 20, along with its anchoring chains 21, is of sufficient mass to gravity-anchor the system firmly in place during normal usage, i.e., in connection with surface waves up to maximum amplitude with which the system is designed to safely work. Such support can be a rigid structure mounted on the water bed, but is preferably a float 16 secured to an anchor base 20 anchored to the water body floor by the weight of the anchor base 20 plus that of anchoring chains 21, as hereinafter described. With further increases of wave amplitude and further forces on the tube 10, the violent impact of the tube top end 12 with the upper buffer system overcomes the weight of the anchor base 20 thereby lifting it off the ocean floor (but not freeing it from its anchors 60). Lifting the anchor base 20 is also an energy absorbing means , thereby further protecting the system.
