For normal operations the buoyancy tanks primarily keep the mouth of the Inlet sufficiently above the Still Water Level and make the system either sink or float completely above the waves as and when required. In another example, say, if a thin and flexible sheet of impermeable material is spread out on a wave train and some water is poured on it, the water will immediately get collected in the troughs and start flowing along with the waves.
Pressure in the Pipe is developed when some resistance is applied at the outlet; say for pumping the water up into a reservoir. If some resistance is applied at the outlet, the water in the troughs will get pushed up the inclines of the previous crests, consequently increasing the pressure in the pipe. The segments get pushed by the waves as they propagate from one end of it to the other. The pressure and flow can be directly converted into other forms of energy, such as electricity, through conventional turbines-generators or pump ocean water into reservoirs, etc. The major challenges with the state of the art WEC’s have been their complexity and survivability, mainly due to the vagaries and harshness of the ocean. Pat. No. 4,672,222 which provides an apparatus for producing electricity from wave motion on a body of water comprising of self stabilized and modularly expandable system of independently operative point absorbers with respective drive transmission and electrical generators.
In another embodiment which is illustrated by FIG. The force which the waves exert in moving each segment relative to its neighbors is captured by hydraulic rams that press fluid into accumulators, which, in turn, power a number of generators. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope. In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. The FFWEC of the present invention comprises essentially of a normally buoyant “Flexible Pipe” of adequate length, or plurality thereof, that floats on the ocean surface and adapts to the wave form, suitably moored so as to maintain the fore and aft axis generally perpendicular to the waves direction. Further, ocean waves posses two types of energy-kinetic and potential. FIELD OF THE INVENTION This invention relates to ocean energy and more particularly wave energy converters (WEC).
This property is valid for waves in water with depths greater than λ/2. Dolor de espalda solo por la noche . This invention exploits this characteristic of the wave motion. Whereas, under operating load the water slugs get pushed up the crest of the preceding wave all along the Flexible Pipe. The device could work without any controlling devices, under fair wave climatic conditions, with average efficiency and reliability.

The required control devices could be located on shore. Whatever control devices required are preferably located on shore. The devices might be highly sophisticated, even more energy efficient, but perhaps, not as cost effective-in terms of cost/kW. Highly cost competitive-Design & Development, Capital, O&M and Production, etc. With the rest of the conditions remaining constant, an increase in the number of Pipes and length would enhance the flow volume and pressure respectively. If resorted to it could cause severe damage to the Pipes. Que causa el dolor en las articulaciones . The inflatable variable buoyancy tanks could be in the shape of doughnuts, as shown in the diagram, spherical or of any other suitable shape as in FIG. At near-shore locations, where reflective waves are expected, additional lengths of ‘rigid pipes’ may be attached to the ‘flexible pipe’ for conveying the fluid flow to the generator housing/turbine or any other energy converter or to a reservoir. The water Slugs get pushed by the waves as they propagate from one end of the Pipe to the other.

Consequently, the flow will stop after all the water slugs flow out. The total pressure in a pipe will be the function of the cumulative differential pressure of all the water segments in that pipe-less losses. Surge/Stall. However, if the backpressure (pressure-head) exceeds the total pressure that is being developed by the Flexible Pipe at any given time, the system surges or stalls. If the backpressure exceeds the total pressure head, the system stalls.

Thus, energy is extracted by virtue of the propagation of waves. El procedimiento usa una aguja bien fina y delgada para inyectar una solución esclerosante estéril en las venas pequeñas. Con uso de una aguja bien fina, el radiólogo de intervención inyecta la solución disolvente de venas en las venas varicosas y de araña.
Las venas varicosas grandes no responden tan bien como las pequeñas a la escleroterapia. Las venas varicosas más grandes que han sido inyectadas pueden ponerse abultadas y/o duras por varios meses antes de resolverse. Se le podría recomendar que deje de tomar aspirina, medicamentos antiinflamatorios no esteroideos (NSAIDs, por sus siglas en inglés), suplementos de hierro, o desespesadores de la sangre por varios días antes de su procedimiento. Debido a que se le podría pedir que se ponga una bata, le convendría traer un pantalón corto para usar durante el procedimiento. Posiblemente le proporcionen una bata para que use durante el procedimiento. Hay que esperar por lo menos tres meses después de dar a luz antes de poder ser considerada para este procedimiento. En la mayoría de los casos desaparecen dentro de tres a seis meses, pero sí pueden ser permanentes en un cinco por ciento de los casos. Cada tratamiento generalmente resulta en la eliminación del 50 al 80 por ciento de las venas inyectadas.
