Thus, flood valves 28 enable the piston 10 to be drained when the surface of tidal water is below or level with the valves, and to be filled with water when the water surface is at least level with the top of the air chamber of piston 10. The valve may be remotely controlled for electric, hydraulic, or pneumatic operation in any manner known in existing valve control technology.
The above described embodiment is exemplary only and it is not intended to limit the scope of the invention beyond what is claimed below. The ram pistons 20 are disposed in ram cylinders 22 normally filled with hydraulic fluid and forming part of the hydro-electric power generating systems to be described below.
The design parameters of the auxiliary piston are calculated so that the piston will slowly rise when it is released so that the water chamber 54 will surface by a predetermined amount at high tide. 4 about when the surface of water is at level H corresponding to its high tide level. When the primary piston 10 reaches its upper end of stroke (shown in phantom lines in FIG. When the surface of water rises approximately to level WL in FIG.

Since a large quantity of water is contained within the chamber of the primary piston, a substantial amount of energy is available to produce work during the downward stroke of the piston. The described cycle is repeated so that useful work is produced on both the upward and downward stroke of the primary piston. The size of the hydraulic ram unit would be carefully selected to enable the generation of a suitable pressure in the hydraulic fluid that can be utilized to drive an electromotive generator or alternator 32 through hydraulic motor 34. A pressure accumulator 36 can be charged while the ram piston 20 is moving so that the motor 34 can be continuously driven even when the piston 20 is stopped at its stroke ends. The chamber is cyclically filled with air or water at its lower and upper positions, respectively and is connected to an hydraulic ram that converts the reciprocating motion of the tidal piston to hydraulic pressure that in turn is used to drive a motor connected to an electrical generator.

Accordingly, one or more primary pistons arranged to produce useful work is each provided with a large hollow chamber that can selectively be filled with water or air and sealed against the ambient. The auxiliary piston is supported so that it can rise to a sufficient level so that the bottom of the water chamber is approximately level with the upper end of the chamber in the primary piston to insure that the primary piston will be filled with water.

Cuando se activa la vía clásica (como en el lupus eritematoso sistémico), el consumo empieza en los primeros componentes, que por ende estarán disminuidos. Dado que la proteinuria y la hematuria son hallazgos típicos, en la primera evaluación clínica habrá que determinar si hay proteinuria y, si la hay, cuál es su magnitud, la presencia de hematuria asociada, el desarrollo de insuficiencia renal y la existencia o no de hipertensión arterial.
