Title: Wind power plant and wind-power-plant control method
Inventor: YASUGI AKIRA
IPC: F03D7/00
Filed: 2011-02-10
Abstract: A wind power plant (50) includes a wind turbine generator (10) and an electrical storage device (54) that supply electric power to a utility grid. A wind-turbine controller (52) performs for the wind turbine generator (10) an acoustic--noise suppression operation in which the rotational speed of blades is controlled in order to suppress acoustic noise generated through rotation of the blades, and also calculates a reduction in output power that is the difference in output power between the normal output power obtained when a normal operation is performed and the acoustic-noise-suppression output power obtained when the acoustic-noise suppression operation is performed. An electrical-storage-device controller (58) causes the electrical storage device (54) to be charged or discharged, based on the reduction in output power, the acoustic-noise-suppression output power, and the grid-demanded output power demanded from the utility grid.  Therefore, the wind power plant (50) can supply, to the utility grid, the electric power demanded from the utility grid even when the operation of suppressing the occurrence of acoustic noise is performed for the wind turbine generator (10).

Title: Process for the production of chlorinated and/or fluorinated propenes
Inventor: KRUPER WILLIAM J JR
IPC: C07C21/067
Filed: 2009-10-09
Abstract: The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures relative to conventional processes, so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts may provide enhancements to conversion rates and selectivity over those seen in conventional processes, as may adjustments to the molar ratio of the reactants.

Abstract: A protective sleeve having an external sound-amplifying member is configured to cover a portable electronic product having an audio port, and it includes a covering element covering the portable electronic product and a sound-amplifying member. A surface of the covering element is provided with a connecting hole in communication with the audio port. The sound-amplifying member is hollow and connected to the outside of the covering element. One end of the sound-amplifying member is formed into an insertion section inserted into the connecting hole, and the other end thereof is formed into a sound-amplifying section. The sound of the portable electronic product is emitted from the audio port and amplified through the sound-amplifying member and the sound-amplifying section. By this structure, an external loud speaker is unnecessary, and the protective sleeve itself can generate a sufficient sound-amplifying effect, thereby increasing the functionality and practicability of the protective sleeve.

IPC: A61K9/28
Filed: 2009-12-16
Abstract: Disclosed is a misuse preventative, controlled release composition in the form of a multilayered oral dosage form.  A first layer contains a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed therein. The second layer, which can be adjacent the first layer comprises a pharmaceutically active agent that can be the same or different from the pharmaceutically active agent in the microparticles in the first layer. The composition further comprises a superabsorbent material (for example, polycarbophil) disposed within the first layer, the second layer, or both the first layer and the second layer. When intact, the pharmaceutically active agent is released from the second layer faster than the pharmaceutically active agent in the first layer. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material present swells to encapsulate the micioparticles, which remain substantially intact thereby retarding the release of the pharmaceutically active agent from the composition. Also disclosed is a method of using the misuse preventative, controlled release composition to deliver at least one pharmaceutically active agent to a mammal, for example, a human, in need thereof.

Filed: 2009-12-17
Abstract: Processes produce a lithium vanadium fluorophosphate or a carbon-containing lithium vanadium fluorophosphate. Such processes include forming a solution-suspension of precursors having V" that is to be reduced to V". The solution-suspension is heated in an inert environment to drive synthesis of LiVPO4F such that carbon residue forming material is also oxidized to precipitate in and on the LiVPO4F forming carbon-containing LiVPO4F or CLVPF. Liquids are separated from solids and a resulting dry powder is heated to a second higher temperature to drive crystallization of a product. The product includes carbon for conductivity, is created with low cost precursors, and retains a small particle size without need for milling or other processing to reduce the product to a particle size suitable for use in batteries.    Furthermore, the process does not rely on addition of carbon black, graphite or other form of carbon to provide the conductivity required for use in batteries.

Abstract: A baby/infant seat, through which the child's legs pass and which secures the child up to his or her chest, is situated within a circular void found in the centre of a flat, rigid larger circular surface/play space, supported by wooden legs extending downward and outward. The seat is attached to the play space by means of a turntable bearing, which allows a baby or infant seated therein to turnabout by means of either hand or foot action. The play space is occupied by any number of baby or infant toys or implements attached thereto by means of suction cups, allowing for variation in the location and type of toys or implements selected. Located between the play space and lower surface is another flat plane, the height of which may be adjusted by means of inserting attachment members for the flat plane into any of three alternate attachment holes prepared into the supporting wooden legs, which serves as an adjustable surface reached by the legs of the child. The entire design is capable of being inverted thereby causing the lower space to become a tabletop. In so doing, the previous play space is detached by means of disengaging a custom bracket system. The result is an infant's table with three styled legs.  The in between space may be kept in place and used as a shelf.
