| 20100126502 | SELF-SEALING T-PIECE AND VALVED T-PIECE - Apparatus ( | 05-27-2010 |
| 20100172698 | SYSTEM AND METHOD FOR THE DEPLOYMENT OF A HYDROELECTRIC TURBINE - The present invention is concerned with a system and method for the deployment of a hydroelectric turbine, and comprises a base and vessel beneath which the base can be secured, and to which base, from above deck, a hydroelectric turbine can be secured to the base and subsequently released with the base from the vessel. | 07-08-2010 |
| 20100232885 | METHOD OF INSTALLING A HYDROELECTRIC TURBINE - The present invention provides a method for installing a hydroelectric turbine at a deployment site on the seabed which involves lowering the turbine and associated base onto the seabed from a vessel using a number of lines, and once on the seabed using these lines to tether the vessel to the base/turbine while telemetry from the base/turbine is analysed. | 09-16-2010 |
| 20100295388 | HYDROELECTRIC TURBINE GENERATOR COMPONENT - The present invention is concerned with a hydroelectric generator component forming part of an electromagnetic circuit for generating electricity from tidal flows, the component including a wire wound coil or a magnet housed within a casing and secured therein by means of a filler material, such as to provide structural integrity and impact protection to the coil or magnet. | 11-25-2010 |
| 20110018274 | HYDROELECTRIC TURBINE WITH FLOATING ROTOR - The present invention is concerned with a hydroelectric turbine which includes a stator and a shaftless rotor housed for rotation within the stator, the stator defining an opening or channel in which the rotor is retained and which channel is dimension to permit the rotor to undergo both axial rotation and displacement along the circumference of the opening, whereby during operation the rotor assumes substantially hypocycloidal motion relative to the stator. | 01-27-2011 |
| 20110088253 | TURBINE INSTALLATION METHOD - The present invention provides a method of installing a hydroelectric turbine onto the seabed or the like while ensuring that a pre-laid electrical cable connected to the turbine prior to lowering to the seabed is not damaged during installation of the turbine, the method involving lowering the turbine towards the seabed while simultaneously displacing the turbine in order to maintain tension in the electrical cable. | 04-21-2011 |
| 20110110770 | HYDROELECTRIC TURBINE HAVING A MAGNETIC BEARING - The present invention provides an open centred hydroelectric turbine having an annular stator and a rotor mounted for rotation within the stator, the turbine comprising a magnetic bearing which is adapted, by having opposing sets of rotor and stator magnets which are offset at a top and bottom of the stator, to provide both axial and radial support to the rotor. | 05-12-2011 |
| 20110291419 | HYDROELECTRIC TURBINE WITH ALIGNING MEANS - The present invention is concerned with a hydroelectric turbine system with aligning means which enables a hydroelectric turbine system, comprising a base and a turbine mounted thereon, to be lowered to the seabed in a running tide while effecting and maintaining stability and a desired orientation of the system. | 12-01-2011 |
| 20110293399 | HYDROELECTRIC TURBINE WITH PASSIVE BRAKING - This present invention relates to a hydroelectric turbine having a stator and a rotor within the stator on at least one set of bearings, the turbine having a brake which becomes operational following a predetermined level of bearing wear in order to avoid damage to the turbine. | 12-01-2011 |
