2º Foro Del Colegio Nacional De Neurocirugía A.C. En La Cámara De Diputados 11 de Diciembre del 2018 Fallis discloses a buoyant sealed tank having a pair of racks upstanding therefrom, which is vertically guided and allowed to rest in and on a body of water. U.S. Pat. No. 3,894,241 issued July 8, 1975 to S. Kaplan discloses a power source which is powered by the energy in water waves that has a frame which supports a shaft above the waves. However, any attempt to move the improved tank upwardly relative to the surface of the water contained within the tank will be resisted by the product of the negative pressure times the surface area of the cross section of the interior tank at the intersection of the surface of the water therein and the vacuumized interior thereover. The negative pressure within the tank, causes water to enter the tank in the lowermost regions thereof across the open mouth portion and to be maintained therein so as to effectively “clamp” the tank to the water.

Dolor de la mano foto de archivo. Imagen de fuerza, pecho.. Alternatively, collar 64 may be sealed off, containing air therein for floatation purposes. If desired, any and all of the floatation compartments or the floatation collar may be coupled to a source of compressed air which is used to maintain such collars full of air, providing buoyancy for the tank. Alternatively, a flexible chain, rope or the like may be employed, having the lowermost regions thereof secured to an eye-bolt-like device, fastened to the exterior surface of the cap portion of the tank. 1 showing a floatation tank 10 shown guided by vertical posts 12 and 14. Such vertical posts are secured to platform 16. Racks 18 and 20 engage gears 22 and 24 respectively.

Such vertical posts are required because the Fallis tank is susceptible to horizontal motion of the water about the tank which tends not only to displace the tank laterally but tends, more importantly, to shift the line of motion of the tank away from the vertical. Hollow pipe 56 is secured to cap end 46 and has end 58 thereof communicating to the interior of tank 36. Hollow flexible pipe 60 is shown having end 62 thereof engaging collar 38, and communicates to the interior thereof. Calmar dolor de rodilla . A floatation collar or compartment may be secured to the tank. 1. Tab ears 50, secured to collar 38, utilize bolts 52 to secure collar 38 to surface 40. Bulbous portion 54 of tank 36, is shown located adjacent end 44 thereof. A rigid post, rod or other member may be secured to the exterior of the tank for purposes of transmitting the forces exerted on the tank by the body of water supporting same, when such tank moves upwardly and downwardly.

A floatation collar or sealed chamber of any desired type is secured to, or made integral with, the container at a location adjacent the uppermost regions thereof. This is accomplished by utilizing an inverted open mount container, of any convenient size or shape, having a rigid or flexible member affixed to the uppermost regions thereof for use in communicating the force generated by the tank motion in an upward and downward position. Another advantage of the present invention is an improved tank for use in wave motors which tends to maintain itself in an upright position at all times. Such device includes hydraulic pumps which in turn operate hydraulic motors driving electric generators, rotating shafts which in turn drive electric generators and the like. Such tanks frequently require vertical guidance and utilize cables, chains or rigid members, which when coupled to the tank, transmit a force therealong due to the displacement of such tank when the tank shifts its position in response to wave motion and the tides.

Alternatively, a permanently sealed floatation collar may be employed.

Another object of the present invention is to provide an improved tank for use in wave motors which tends to maintain itself in an upright position at all times. Another object of the present invention is to provide a floatation tank for wave motors which increases the efficiency of converting water motion to a suitable form of energy derived therefrom over existing floatation tanks. SUMMARY OF THE INVENTION A primary object of the present invention is to provide an improved wave motor tank which is effectively locked to a body of water regardless of the size of the tank employed. Alternatively, a permanently sealed floatation collar may be employed. Prior art floatation tanks, of any size, had to be constructed such that the tank possesses sufficient strength to maintain the tank in floatable condition whilst allowing the tank to be buffeted by the action of waves and tides of the water supporting same.

The floatation collar or buoyancy void or compartment must be of sufficient size so as to provide a buoyant force to the improved tank, maintaining same in a floating condition. Vertical columns 32 provide vertical support to platform 16, when positioned over a body of water 34. Dolor de hombro al moverlo . Such prior art apparatus is disclosed in U.S.

This invention relates to improvements in wave motor tanks and more particularly to that class of wave motor tank which is useful at extracting energy from tidal and wave motion of large bodies of water due to the rise and fall thereof. Thus, there is disclosed in the above description and in the drawings, an embodiment of the invention which fully and effectively accomplishes the objects thereof. 1. Dotted lines 74 simulate the uppermost level of water contained in region 76, in the interior of tank 36 when region 78 thereof experiences negative pressure.

As long a such buoyant force is slightly greater than the weight of the improved tank and the force exerted by the negative pressure or vacuum therewithin, the improved tank will float. Thus, the tank may be adjusted so as to move upwardly and downwardly, expressing moderate forces on the shaft or cable coupled thereto, or, if desired, may communicate great forces upon increasing the negative pressure so as to exert a great downward force, much greater than the actual weight of the tank, when the water level descends. Since the force of the negative pressure is exerted on a broad area, equivalent to the open mouth portion of say, a cylindrical tank, such downward force may be massive indeed.

A negative pressure is caused to be experienced in the upper closed end region of the tank, utilizing a flexible hose coupled to a vacuum pump, if desired therefor. On each float there is mounted a second pulley which engages the other end of the chain, the second pulley having a second releasable ratchet. The columns pass through openings in the platform and each engage a pair of pinion gears, carried on a common shaft, each pinion is mounted on a separate one-way clutch such that the shaft is caused to rotate in one direction at all times, responsive to the buoyant forces directing the tank in an upward direction as the tide comes in, for example, and responsive to the weight of the tank when the tide goes out.

Similarly, swells and wave motion further cause the output shaft to rotate in the same direction due to the waves’ effect upon the tank. A further object of the present invention is to provide an improved floatation tank which may be easily and effectively transported from place to place, possessing a low weight. Since the improved tank is “clamped” to a given body of water and since the improved tank experiences the effective weight of a much heavier tank, the improved tank tends to require less vertical guidance than prior art tanks. Yet another object of the present invention is to provide an improved wave motor tank which has an effective specific gravity of zero when disposed in a “floating” position in a body of water. Yet another advantage of the present invention is an improved wave motor tank which has an effective specific gravity of zero when disposed in a “floating” position in a body of water.

Since it is presumed that the tank is always in contact with the water, the buoyant forces are always at work. A further advantage of the present invention is an improved floatation tank which may be easily and effectively transported from place to place, possessing a low weight. Friction, induced by the vertical posts providing vertical guidance for the tank, further diminishes the efficiency of the system. The output shaft is provided with a pulley for purposes of coupling such shaft to an electric generator or the like. Typical of such a wave motor, is the apparatus taught in U.S. The rigid member or the flexible rope-like member is coupled to any wave motor device useful in translating reciprocal motion into convenient forms of energy, well known in the art. Therefor, this invention is to be limited, not by the specific disclosure herein, but only by the appending claims. Como calmar un dolor muscular . Each of the gears utilize a one-way clutch, typified by clutch 26, in driving output shaft 28. Pulley 30 is utilized in providing output power to a belt, not shown.
