A flow conduit is provided having an inlet and an outlet with an impeller located in the flow conduit; and a generator connected to the impeller. As a general rule, the minimum distance by which the first and second areas are spaced apart is the shortest distance measured along a straight line extending between these first and second areas when they are separated from each other with the separation limiting means limiting this separation between the first and second areas. As can be seen in Figures 1 to 5, 7, 8, 10, and 13 to 16, at least some of the separation limiting means 18a, 18b are connected, respectively, to a plurality of intermediate points 17a, 17b of attachment to the membrane, separated from each other and located between the first and second areas 6, 8 of the membrane.
Each series of intermediate points of the membrane is connected to a corresponding series of springs. Figure 1 shows a series of SMEC tubes 1 , which may have open or closed tops, set across a tidal flow. This induces a secondary flow 9 out through the slots 11. This small pressure drop across a very large number of venturi orifices induces a large volume, high cross- sectional area, low velocity secondary flow 13 through the manifold piping 15. This large body of slow moving water is fed by water flowing past the impeller via a shroud 17 of significantly less cross-sectional area to provide a local flow velocity that is higher than that of the manifold. Conversely, if the velocity of movement of the second area of the membrane along the axis Z-Z perpendicular to the fluid flow 2 becomes too great with respect to a predetermined high velocity of movement, the value of the resistive force is made to increase and the velocity of the membrane then decreases.

The bending elasticity of the membrane is therefore chosen as follows: – as a function of the type of fluid flow in which it is to be immersed (density of the fluid and velocity of flow); and – as a function of the separation of the first and second areas 6, 8 from each other; and – as a function of the mass of the membrane and the mass of the converter or converters, notably if this converter is carried by the membrane, the forces due to the stiffness being required to compensate the inertial forces due to the masses; and – as a function of the amount of energy which it is desired to recover from this fluid flow. Offshore tidal barrages have been proposed to concentrate the incidental energy of a large cross-section of water flow by trapping the flow behind a containing wall and funnelling it through turbines of much smaller cross- sectional area, as in a conventional dam.
The volume of the induced secondary flow in a SMEC barrage can be made as large as desirable by increasing the size of the SMEC which is infinitely scaleable. Thus there is a reduced risk of unwanted bending of the membrane which might cause the membrane to twist along the fluid flow, which might damage it and lead to a reduction of the amount of energy extracted from the flow.
The head deflector 19 which is placed at the start of the membrane (in other words, at its first area 6, along the upstream edge 4c) facilitates the initiation of the wave, because, when it is subjected to a flow, it pivots about an axis perpendicular to the longitudinal sectional plane P of the membrane and forces the membrane to pivot and undulate in the flow. Thus the membrane is forced to curve between the first and second areas 6, 8, and is forced to undulate when immersed in a fluid flow.
This device of Figure 12 also includes means for limiting the separation of the first and second areas of the two membranes 4a, 4b. For example, these separation limiting means may consist of a stop which sets the distance D of the downstream bar 13b of the transmission means with respect to the upstream bar 13a of the attachment system in such a way that it is less than the length L of each of the membranes (these membranes 4a and 4b being identical to each other, in other words having the same dimensions of length, width and thickness, and being formed from the same material).
For example, Figure 15 shows that the head deflector 19 and tail deflector 20 are molded directly with the membrane in its first and second areas 6, 8 respectively. The length of the pipes or tubes of each SMEC module 12 are selected to suit the depth of the prepared foundation below the water level with the objective of maintaining the upper parts of the modules at essentially the same height. The module is lowered into place between the pre-dhven sheet-piled revetments 16. Once seated in the foundation, any gaps around or underneath of the SMEC barrage modules are sealed with grout 40. The modules 12 need only be joined to one another at road or railway level. Each SMEC barrage module 12 is fabricated from concrete and/or steel in a temporary or local dock, so as to be able to take advantage of slip- forming and other cost saving fabrication techniques.

Figure 5 shows a cross section of a SMEC barrage module 12 installed on its foundation terrace 10. Each terrace is formed by sheet-piling a linear revetment 16 into the river or sea bed to suit the width of the base section 18. La gastritis provoca dolor de espalda . The river or sea bed is profiled by dredging and/or gravel dumping 20 to protect the river bed from erosion and guide flow through the SMEC module. Furthermore, the membrane perturbs a fluid stream having a cross section greater than the cross section representing the width of the membrane multiplied by the amplitude of the wave, and therefore it captures energy from the fluid in a space considerably larger than its overall dimensions.

Owing to this longitudinal reinforcer 23 which increases the longitudinal stiffness of the membrane, the mechanical coupling of the membrane to the force transmission means 12 and consequently to the energy converter 14 is improved. As shown in Figures 1, 25a, 25b and 26, resilient stiffeners R can be installed to oppose resiliently the movement of the first area 6 of the membrane 4 on either side of a position (for example, a central position of this first area which is assumed when the membrane is at rest). These first and second orientation axes 32, 33 are arranged in planes which are perpendicular to each other, such that the first orientation axis 32 can be placed in a horizontal plane while the second orientation axis 33 is placed in a vertical plane.

Preferably, each rotary generator of the group is arranged in such a way that its arms 16b1 are attached to the membrane 4 and its natural generator axis 16b2 is perpendicular to the longitudinal sectional plane P of the membrane. The nozzle array can be disposed in the projection of the plate surface of the piezoelectric flexural transducer in its direction of motion or in the extension of the piezoelectric flexural element or in another suitable pattern. Gaps are formed between the edges lateral to the direction of overhang an the free end of the piezoelectric flexural transducer ad adjacent section of the housing wall. In a pump chamber connected to a liquid supply, an overlapping piezoelectric flexural transducer is disposed so that when voltage pulses are applied to produce an excursion, a number of droplets can be expelled from a nozzle array in the housing wall of the pump chamber using a plurality of nozzles.
As part of a combustion device the droplet mist generator is excellent for producing a combustible fuel-oxidant mixture. Further aspects of the invention will be apparent from the following description. Dolor muscular por tos . Figure 14 shows a second embodiment of a module according to the invention. Thus, under the effect of the fluid stream, the membrane undulates in an alternating, quasi-sinusoidal shape. These longitudinal ridges 22 also enable the longitudinal stiffness of the membrane to be increased. Vf, where Z is a differential coefficient between the velocities Vm and Vf.

De hecho, si el riesgo de consumo excesivo no afecta a todos los oligoelementos y sales minerales, si está presente en el caso del magnesio. Es principalmente por estas razones que se nos recomienda consumir magnesio en caso de fatiga e irritabilidad. Debe saber que el magnesio es un oligoelemento que no debe consumirse en exceso. Debido a sus efectos sobre la relajación muscular, este oligoelemento también sería beneficioso contra la tensión, el estrés y la ansiedad. Este oligoelemento permite una contracción muscular normal. Este efecto sería aún más importante con una combinación de magnesio / vitamina B6, como lo demuestra un estudio sobre el tema. No intente automedicarse en este contexto, ya que existe el riesgo de un consumo excesivo. A medida que aumenta la solubilidad del calcio y especialmente en la orina, el magnesio podría tener un efecto preventivo sobre los cálculos renales.
