20110295437 | WIND POWER CONVERTER SYSTEM WITH GRID SIDE REACTIVE POWER CONTROL - The present techniques include methods and systems for operating a wind power system to maintain a lifespan of the rotor side converter. In some embodiments, the current of the rotor side converter may be minimized to reduce the stress and/or junction temperature variation in the switching transistors and bond wires of the converter. More specifically, embodiments involve using a minimal current in the rotor side converter based on the rotor side and grid side reactive powers. If the grid side reactive power is greater than a maximum grid side reactive power, the grid side reactive power may be reduced. Further, if the total reactive power does not meet the grid reactive power requirements, the minimal current in the rotor side converter may be adjusted such that the system may sufficiently power the grid. | 12-01-2011 |

20150090673 | APPARATUS AND METHOD FOR PURIFYING LIQUID - The invention relates to an apparatus and a method for purifying liquid. The apparatus comprises an air-tight container (301) and a heater (305). The air-tight container is configured to store the liquid, wherein at least a portion of the container consists of a filter membrane (303). The heater is configured to heat the liquid such that the liquid is driven out of the container through the filter membrane. The heater can actively increase the pressure in the container by heating the liquid and/or gas in the container. Sometimes, a portion of the liquid stored in the air-tight container may be vaporized, which increases the pressure in the container as well. Under the increased pressure, the liquid can be easily driven out of the container while being purified via the filter membrane. Since the filtration is actively driven by heating, the filtration efficiency of the apparatus can be controlled and improved according to various applications. | 04-02-2015 |

20150336102 | MAGNETIC TUBE RACK - A system for holding sample tubes used in immunoprecipitation and similar laboratory techniques. A rack comprises top and bottom plates spaced apart from each other and defining rows of holes to receive the sample tubes and hold the sample tubes in a pair of spaced-apart rows. A magnet holder is configured to slide between the top and bottom plates and between the two parallel rows of sample tubes such that when the magnet holder is fully inserted between the rows of sample tubes, magnets held by the magnet holder align with the sample tubes in the two parallel rows. | 11-26-2015 |
