Abstract: A waterwheel assembly for a river or similar body of flowing water includes a waterwheel mounted on a support structure, and one or more buoyant members, wherein waterwheel can move up and down, and the buyout members support part of the weight of the waterwheel so that the waterwheel is able to rise and fall with any change to the river level, and the support structure is secured on land by the river or body of water by means of one or more cantilevered beams. The waterwheel has an axle secured between two vertical posts by means of salable bearings that permit the waterwheel to move up and down.

Abstract: An energy generating device having a drum and at least one vane that is movable between a deployed state and a stowed state as the drum rotates to capture energy potential from flowing water and converting it to usable electrical and/or mechanical energy. The movable vanes can automatically retract when not in the flow of water and re-deploy when entering the flow of water over the drum. The present system can generate usable electricity or mechanical energy from slow but steadily flowing bodies of water without the need to dam, restrict, or alter the path of the water flow.

Abstract: An artificial reef to be anchored to the seabed comprises two or more juxtaposed conduits which are positioned in parallel with the direction of wave propagation. Both conduits include directrices. The upper conduit includes directrices which drive the flow of the wave's crest, and the lower conduit includes directrices which drive the water diverging from the apertures in the area under the wave's trough. The upper and lower conduits are hydraulically connected, each connection comprising a shut-down valve associated with a useful energy-generating unit.

Abstract: This invention relates to an artificial reef to be anchored to the seabed, basically comprised of two or more juxtaposed conduits (1) and (2) which are positioned in parallel with the direction of waves propagation, both conduits being provided with directrices (3) and (6), the upper conduit having directrices (3) which drive the flow of the wave's crest (4) converging to the entries (5), the lower conduit also having directrices (6) which drive the water diverging from the exits (8) in the area under the wave's trough (7), all of these apertures being provided with flexible filters made from fabric, which will smoothly control the abrupt reflux of flow. The said conduits are hydraulically connected, each connection comprising a shut-down valve associated to a useful energy-generating unit (9).In case the main components of the device shall not be in direct contact with seawater, the device also comprises pads (11), (12) and (13), which are made from a thin flexible material, such as rubber, and cover all the existing entries (5) and exits (8) in the said conduits, each pad being simultaneously connected to entries and exits in the same vertical line of the same segment of the device, with the conduits and pads being internally filled with a fixed amount of fluid which thus remains fully isolated from the seawater.

Abstract: An exemplary axial flow steam turbine is disclosed which includes a motor, a turbine casing and at least first and second turbine stages, with the second turbine stage being located adjacent to and downstream from the first turbine stage. A radially outer static diaphragm ring of the second turbine stage includes an annular axial extension extending in an upstream axial direction and carrying a circumferential tip sealing device which cooperates with shrouds of a circumferential row of moving blades of the first turbine stage. An upstream end of the annular axial extension is axially spaced from a radially outer static diaphragm ring of the first turbine stage such that a circumferential passage is defined between the upstream end of the annular axial extension and the radially outer static diaphragm ring of the first turbine stage. Solid particles are diverted from steam flow by a circumferential passage during operation.
