Abstract: An apparatus for generating electric power from water currents comprises a housing having at least one pair of channel, at least one pair of turbine assemblies and at least one pair of generator assemblies. Each channel of the pair has an axial intake, an axial discharge opening and a side intake. Each side intake extends along a length of the channel and faces in an upstream direction to receive a side inflow of water and directs the side inflow up against an interior surface of the channel to create a vortical flow structure having a low pressure core. The vortical flow structures are produced downstream of the turbine assemblies to effect an increase in a pressure drop across each of the turbine assemblies. The apparatus also has partition extending between the channels near said axial intakes.

Title: In situ heavy oil and bitumen recovery process
Inventor: GATES IAN DONALD
IPC: E21B43/16
Filed: 2007-07-13
Granted: 2012-10-02
Abstract: The present invention is directed to an in situ reservoir recovery process that uses a horizontal well located near the top of a reservoir and an inclined production well to extract bitumen or heavy oil from a reservoir. The process may consist of a first stage in which the top well is used for cold production of reservoir fluids to the surface. In cold production, reservoir fluids are pumped to the surface in the absence of stimulation by steam or other thermal and/or solvent injection. In the present invention, a lower production well is drilled into the formation below the top well. The top well is converted to an injection well or, if no cold production then a top well is drilled as an injector well. A portion of the bottom well is inclined so that one end of the incline is closer to the injector well than the other end of the incline. Alternatively, the new bottom well is inclined at an angle so that the interwell distance between the toes of both wells is less than the interwell distance between the heels of both wells. In the process, steam circulation creates a heated zone at the point of the two wells that are closest together in the reservoir. For example, for an inclined bottom well, this is at the toes of the wells. After thermal communication between the two wells is established, then the wells are switched to a SAGD-like mode: steam or other injectants are injected into the top well and reservoir fluids are produced from the bottom well. The process preferentially produces the relatively lower viscosity oil from the upper portions of the reservoir in the early stages of the process. Later, as the steam chamber expands downwards into the reservoir along the wells, the produced oil contains higher amounts of the heavier, higher viscosity oil found nearer the bottom of the reservoir. The process is particularly useful in the recovery of heavy oil or bitumen from a reservoir that exhibits vertical and lateral areal oil phase viscosity variations. The method is also very useful in reservoirs with bottom water.

Abstract: A battery pack is provided for use when charging of a dedicated secondary battery in a portable terminal device is difficult. The battery pack is mounted in a battery mounting section in a portable cellular phone. In the battery pack, alkaline accumulators are connected in series. Alkaline accumulators generate electromotive forces having a voltage (3V) being lower than that of the dedicated secondary battery. A power source circuit has a boosting--type DC/DC converter which boosts a voltage of the alkaline accumulators being connected in series at a level same as that of the dedicated secondary battery (for example, 4.5V), and outputs the boosted voltage. An electrical double layer capacitor has a capacity to feed stable power to an internal circuit in which power consumption increases or decreases in a burst manner and is charged by application of an output of the power source circuit and stores the power.
