Profundo dolor en el estudiantado universitario y en la.. 2, the load release and re-establish means presented at 202c is a hydraulic valving system which is just one of several possible load release and re-establish means configurations. 10. At a point between where the lever arm 107 is attached to the trunnion block 302 and to the wave follower 20 at trunnion pin 108, said lever arm 107 is also pivotally attached by yet another trunnion pin 109 or similar device to the inner floatation unit 100. These trunnion pins 109 are located in each of the slots 121 in the inner floatation unit 100 where the lever arm 107 passes through said inner floatation unit 100. The trunnion pins serve as immovable fulcrums about which the lever arms 107 may operate and are located at a point in the lever arms 107 such that a mechanical advantage can be achieved due to there being a greater distance between the trunnion pins 108 and 109 than between the trunnion block 302 and trunnion pin 109. The mechanical advantage gained by this leverage allows the force of the rising and falling wave follower 20 to be increased on the reciprocating drive shaft 174 in order that a greater pressure may be achieved in the hydraulic pumping cylinder 28/FIG. 10. In this embodiment as seen at 211 in FIG.

Further embodiments of a Wave Energy Converter being solidly attached to ground or another immovable body are not shown as they do not differ significantly in operation from those pictured in the included figures other than they do not require the use of reaction plates or damper plates and their means of attachment to any fixed body are much varied and of well known technology. Thirdly, it prevents water from pooling on top of the wave follower 20, thereby causing reduced efficiency and fourthly, it serves as a safety barrier for service personnel who may be atop the apparatus 210. An openable porthole 98 is installed in the domed enclosure 97 to allow for convenient access and egress. As the wave follower 20 rises and falls, thus rotating back and forth on an arc about it’s fulcrum 24, the lever arm extensions 172 rock back and forth as was the case for previously described units in FIGS.

FIG. 16. describes a mechanical load release and re-establish means wherein a solenoid switch 195 momentarily withdraws and then reapplies a solid pin 199 or other such member into a slot or keyway 200 in an extension 301 of the rack 81 such that the rack 81 is freed to slide laterally a given distance before the pin 199 is forced back into a second keyway 201 by the solenoid switch 195. Dolor en mitad de la espalda . The extension 301 of the rack 81 is mounted in bearings 202 which are in turn fixedly mounted inside a sleeve 300. These bearings 202 allow the extension 301 of the rack 81 to travel back and forth in the sleeve 300 when the solenoid pin 199 is withdrawn, thus releasing the load (as was the case described in FIG.

A floatation collar 58, being fixedly attached to the side panels 49, the rear panel 48 and optionally to the funnelling panels 50 but not across the open front 53, provides this floatation. The apparatus 201 floats in a body of fluid such as an ocean, with an upper portion being above the height of the significant waves on the surface 52 of the fluid. First, it, along with the side panels 49 and the rear panel 48 enclose and focus much of the potential wave energy onto the wave follower 20 making this a wave termination apparatus. At 214a is seen a set of three reaction plates 60 which are fixedly and immovably attached at 61 to the support member 59 of a floating wave energy converter. 2,081,381-4 (Vowles) wherein all rights previously held by Bruce Vowles of Kitchener, Ontario, Canada have now been assigned to co-inventors Alan K. Vowles of Flin Flon, Manitoba, Canada and Gerald J. Vowles of Belleville, Ontario, Canada.

A more detailed view of the pump assembly 202a and more particularly the load release and re-establish means 202c have previously been explained in FIG. While FIG. Dolor lumbar al hacer abdominales . 10 goes on to explain the further workings of the wave energy converter apparatus as seen at 210, it should be noted that FIG. SUMMARY OF THE INVENTION The present invention seeks to provide a more efficient apparatus for the extraction of energy from waves on a body of fluid on both the rise and fall of said waves. Also a more detailed view of one of the integrated sensor/switch/valves 45 has previously been explained at 203a in FIG. FIG. 5 is a detailed modified perspective view of a device similar to that in FIG.

This is done in a manner which allows any linked driven component or device to accomplish more work than would a similar apparatus without this novel feature. 1. is replaced with an inner floatation unit 100 which protrudes through the centre of the wave follower 20. Both the floatation collar 58/FIG. 1 and the inner floatation unit 100/FIG. 10 serve the same function in terms of the operating principles of the devices in that they both eliminate the need for the wave followers 20 to use up otherwise convertible energy by holding the complete apparatus afloat. A load release and re-establish means may be any hydraulic, pneumatic, mechanical, electromechanical or other means whose function is to momentarily release the wave follower 20 from the driven and systemic loads of the apparatus 202 such that the wave follower 20 is allowed to find it’s own level without the influence of these load resistances.

10 and showing the linkage setup for the lever arms as well as the wave follower being assembled from sections. As fluid is pushed ahead of the falling piston 27 in the lower part 192b of cylinder 28, thereby reducing the volumetric capacity in that lower part 192b of the cylinder 28, that same fluid is pressurized to a predictable and measurable pressure range which is hydraulically transmitted through pressure tube 46 to sensor/solenoid valve 43. As long as the wave follower continues to fall while tracking the descending wave, the sensor/solenoid valve 43 remains closed, hence allowing the piston to force fluid out of the lower cylinder 192b, through the check valve 40 and on through the outlet tube 41. As the trough of the wave reaches it’s lowest point and then begins to rise, the gravitational force which had been exerted on the wave follower by the falling wave suddenly begins to decrease.
