Abstract: A tidal station includes a plurality of turbine/generator sets removably insertable along the central axis of a caisson to provide a symmetrical installation. Fixedly disposed basin side and sea side diffusers include inlets alternately juxtaposed opposite ends of the turbine/generator sets as the sets are rotatably displaced 180 degrees between ebb and flood tides. Ballasting/deballasting structure contained in the caisson permits self-portability of the caisson to its site and subsequent positioning thereat.

Abstract: A hydrodynamically transformable dam with a fluid path through its main body includes a hydromotive body containing one or more hydromotive assemblies each having a fluid conduit provided with an energy transformation unit. The function of the dam is selectively transformed by controllably displacing the hydromotive body to alternately position its respective conduits relative the main dam body and fluid path whereby either a sluicing action or an energetic transformation is achieved by fluid flowing through the dam. The alternate functions are obtained by fluid flows operating in either a pure hydroelectric mode, a combined reversible pumped-storage manner or a tidal powered mode.

Abstract: A hydromotive assembly for installation adjacent the water passage through a damming structure includes a main body component having an internal draft tube and provided with external guide and support elements allowing displacement of the assembly alternately in a vertical direction or angularly about a vertical axis. One sub-component body includes a water flow conduit containing a turbine generator set having a fixed-vane distributor and is insertable within the main body component in axial alignment with one end of the draft tube while another sub-component body includes a shiftable flow-controlling gate and is insertable adjacent another end of the draft tube. Water-tight chambers in the main body component as well as the sub-component bodies are selectively filled with air or fluid to controllably float, sink or tilt the assembly and allow the installation or removal of the sub-components from the main body component.

Abstract: A hydropowered bulkhead assembly is provided for association with damming or analogous structure defining a water passageway through either non-navigable dams, movable-type dams, chambers at locks defined for navigation procedures, canal drops or auxiliary locks and includes a selectively displaceable body to achieve asynchronous electric generation when disposed in an operative position relative the damming structure. Flow controlling means, such as tainter gates, chanoine wicket gates, miter gates, and the like are included and operable to permit overhauling of the assembly or when in an idle status. Alternatively, a plurality of asynchronous generators may be spliced together in any one bulkhead assembly to enhance the generation quality, dependent upon the requirements imposed by extreme, highly variable hydraulic heads.

Abstract: Self Commanded Hydrostation arrangement for a fluidic storing dam or gated engineered structure, includes a siphon layout conduit with a movable ascending branch having a hydromotive set and a fixed descending branch embodied with said damming structure inducing a fluidic flow therethrough said hydromotive set to produce actuation thereof. Said movable branch being relatively displaceable said fixed damming structure to stop or to start the hydromotive power generation set.Movable gated means are alternatively included helping in both starting and stopping procedures sequences.

Abstract: Transformable hydroenergetic arrangement for a fluid storing dam having a conduit for directing passage of fluid flows therethrough, said fluid directing conduit being dually shaped as a frustum spatial geometrical configuration flaring from the center line of the dam to both of the dam's opposing faces with gated fluid flow controlling means provided along the center line and passing coincidently through the smaller transverse cross-sectional area of the conduit. A hydromotive assembly is alternatively positioned in combination with either flared portion of the dually-flared conduit. The hydromotive assembly includes a turbine runner disposed within a diffuser tube of a body having a flared extension surrounding the diffuser tube and terminating in an open end allowing evacuation of fluid flows.

Abstract: A reversible pump-turbine associated with a fluidic flow directing means defined as a water passageway includes shiftable body component selective displaceable to achieve alternatively, either an energy generation or an energy accumulation mode. One or more fluidic flow directing means are provided each having a, movably engineered or a fixed engineered diffuser body. Selection of energy mode is achieved by rotating the reversible pump-turbine about a verticalized axis, or a horizontalized axis, to position a selected end of its venturi adjacent the end of said fluidic flow conveying means and the other end adjacent said diffuser open end defined in said fluidic flow directing means. If only one conduit is provided, said diffusers are movably engineered into said fluidic flow directing means.
