Síndrome SAPHO - Wikipedia, la enciclopedia libre Background of the Invention Kinetic energy in flowing fluids, such as water and wind, is a known alternative to energy sources such as bio-fuels and fossil fuels for generating power. 2 Summary of the Invention In one aspect, the present invention provides an electrical power generator assembly for using kinetic energy from a flowing fluid to generate electrical power, the electrical power generator assembly including: a blade assembly having a head end for facing incoming flowing fluid, a tail end spaced from the head end for facing in the direction of the flowing fluid, and a rotational axis extending between the head end and the tail end, the blade assembly including a blade arrangement which is arranged in a generally helical fashion about the rotational axis, and at least one mounting formation connected to the blade arrangement, the at least one mounting formation being adapted to permit rotation of the blade assembly about the rotational axis when the flowing fluid interacts with the blade arrangement to rotate the blade assembly; at least one primary coil connected to the blade assembly for rotation with the blade arrangement, the at least one primary coil being energizable and being arranged to interact with at least one stationary secondary coil to generate electrical power in response to rotation of the blade assembly; an elongated open-ended shroud extending between the head end and the tail end, the shroud having a head end section through which the flowing fluid can enter the shroud, a tail end section through which the flowing fluid can exit the shroud, and an elongated intermediate section extending between the head end section and the tail end section, the shroud being connected to and surrounding the blade assembly so that the shroud rotates with the blade assembly; and a stator disposed adjacent the shroud, wherein the at least one primary coil is integrated into the head end section of the shroud and the at least one stationary secondary coil is integrated into the stator.

In one form, the slotted ejector arrangement is connected to, and rotates with, the shroud. In another form, the slotted ejector arrangement is not connected to, and does not rotate with, the shroud. A series of secondary coils 54a and secondary power coils 54b are integrated into the stator 100. In, use, the blade assembly 14 is mounted within the fluid flow 12 which imparts its energy to the blades 44. As the fluid flow 12 applies a force to the blades 44, the 30 blades 44 react by imparting a rotational force or torque to the shaft 24. When a small excitation current 55 is applied to the secondary coils 54a, a magnetic field 56 is created which induces a current in the primary coils 52. The primary WO 2009/062261 PCT/AU2008/001704 9 coils 52 then create a magnetic field 57 which, together with the rotational motion of the primary coils 52, induces a large current inside the secondary power coils 54b that is connected for electricity generation 58. Alternatively, the primary coils 52 can be replaced with permanent magnets that 5 create the magnetic field 57 and induce a current in the secondary power coils 54b for electricity generation 58. In this configuration, the secondary coils 54a and the excitation current 55 are not required.

In the assembly 10f, the shaft 24 is hollow and includes therein tapered roller 30 bearings 70 around a solid structural beam 72, which is bonded to the stator 100 (or other stationary structure). The stator preferably includes one or more blades of adjustable pitch. The electrical power generator, preferably, includes a plurality of said secondary coils. Likewise, in the embodiment where the blade arrangement includes a plurality of beams and said webs or skins, a tip of each web or skin is, preferably, also connected to the shroud. A hydraulic cylinder 82 is connected to one end of the ram 80 and used to extend or contract the ram 80. The other end of the ram 80 is connected to the most outwardly ejector ring 25 108, via supports 84 and a pivot 86. As the ram 80 extends, it applies a force on the pivot 86, the supports 84 and the (end) ring 108, such that the ejector arrangement 102 increases in length (and reduces in diameter).

ALMOHADA POSTOPERATORIO OCULAR - Ubiotex® 24 supported by head end bearings 26 and tail end bearings 28. Stay cables 36 and 38 are attached to the bearings 26 and 28 respectively, which locate the assembly 1Oa and resist movement of the assembly 1Oa in the fluid flow 12. Cremas para dolor lumbar . 30 The blade assembly 14 also has a blade arrangement, in the form of a plurality, in this case, a pair, of equiangularly spaced helical blades 44, and a generally frusto conical shroud 50. Other numbers of the equiangularly spaced helical blades (eg.

Similarly, a reverse force on the ram 80 only contracts the ejector arrangement 102. Although the invention has been described with reference to preferred embodiments, it would be appreciated by persons skilled in the art that the invention may be embodied in many other forms. The helical slotted ejector arrangement 102 can also be constructed from an elastic material such as WO 2009/062261 PCT/AU2008/001704 16 aluminium so it can vary its shape depending on the force applied to it from the strength of the water flow. The shroud head end section 50a, being shaped as a venturi, produces an area of low pressure behind the blade assembly 14 which advantageously results in a much freer flow of fluid through and exiting the shroud 50. Further, as the shroud 50 is bonded to the blades 44, the shroud 50 rotates in conjunction with the blades 44 and the rotational motion of the shroud 50 20 induces a swirl or vortex in front of the shroud 50. This vortex is advantageous as it models a whirlpool (as found in nature) and sucks additional fluid into the blade assembly 14 than would otherwise pass through it. The shroud 50 can also be of unitary moulded construction, for increased strength.

1. 5 In use, the blade assembly 14 is mounted within the fluid flow 12 which imparts its energy to the skin 40 and beams 22. Dolor lumbar tratamiento farmacologico . As the fluid flow 12 applies a force to the beams 22, the beams 22 react by imparting a rotational force or torque to the shaft 24. The beams 22 can also be configured to direct the fluid flow 12 radially inwards towards the shaft 24 in order to minimise fluid escaping the boundary of the shroud 50. io To do this, the beams 22, when viewed in the direction of the axis 20, are twisted and significantly curved inwards (in their direction of rotation) at their ends to act like ‘cups’ and direct the fluid flow towards the axis 20. As the fluid flow 12 continues to flow through the blade assembly 14, the cross sectional area of the flow decreases and its pressure decreases.
