| 20080223684 | SYSTEM FOR GENERATING CONSTANT SPEED OUTPUT FROM VARIABLE SPEED INPUT - An input shaft rotates at variable rotation rates and is driven by a variable source of energy or power such as by the propeller of a wind-driven electrical generator. The input shaft is connected to a clutch which is connected to an output shaft and which is operable to rotate the output shaft at a preselected or constant rotation rate. The clutch has a first rotor which electromagnetically interacts with a second rotor to create a torque to cause the second rotor to rotate. The interaction of the first rotor and the second rotor may be varied electrically or mechanically to vary the torque and in turn the rotation rate of the second shaft. The shaft is preferably connected to a synchronous generator; and the rotation rate of the output shaft is controlled so that the generator supplies power at an essentially constant rotation rate. | 09-18-2008 |
| 20090315329 | Variable Speed Synchronous Generator - An input shaft rotates at variable rotation rates and is driven by a variable speed source of energy or power such as by the propeller of a wind-driven electrical generator. The input shaft is connected to a first rotor which electromagnetically interacts with a second rotor to create a torque to cause the second rotor to rotate. The interaction of the first rotor and the second rotor may be varied electrically to vary the torque and in turn the rotation rate of the second rotor. The second rotor interacts with a stator to produce AC electrical power. The rotation rate of the second rotor is controlled so that the generator supplies AC power at an essentially constant frequency. | 12-24-2009 |

| 20110015419 | SYSTEMS AND METHODS FOR REMOVING CATALYST AND RECOVERING FREE CARBOXYLIC ACIDS AFTER TRANSESTERIFICATION REACTION - Systems and methods for using carbon dioxide to remove an alkali catalyst and to recover free carboxylic acids after a transesterification reaction are disclosed. Generally, the methods include first providing a mixture resulting from the transesterification of an ester, wherein the mixture includes substances selected from the alkali catalyst, an alcohol, and a transesterification reaction product such as biodiesel. Second, the methods generally include adding carbon dioxide to the mixture. In some cases, adding the carbon dioxide to the mixture causes the alkali catalyst to convert into an alkali carbonate and/or an alkali bicarbonate. In other cases, adding the carbon dioxide to the mixture causes the carboxylic acid alkali salt to convert into a free carboxylic acid. In either case, the alkali carbonate, the alkali bicarbonate, and/or the free carboxylic acid can be separated from the mixture in any suitable manner. | 01-20-2011 |
