Title: Power converters
Inventor: JONES RODNEY
IPC: H02J3/38
Filed: 2006-11-13
Granted: 2011-02-16
Abstract: The present invention provides a method of operating a wind turbine including a generator (4) that provides variable voltage at variable frequency and has a stator and a rotor. The wind turbine includes a turbine assembly (2) having at least one blade for rotating the rotor of the generator (4), and a power converter that interfaces the generator (4) to a supply network (NETWORK) operating at nominally fixed voltage and nominally fixed frequency. The power converter includes a generator bridge (10) electrically connected to the stator of the generator (4) and a network bridge (14). A dc link (12) is connected between the generator bridge (10) and the network bridge (14). A filter (16) having network terminals is connected between the network bridge (14) and the supply network. A first controller (18) is provided for controlling the operation of the semiconductor power switching devices of the generator bridge (14). Similarly, a second controller (46) is provided for controlling the operation of the semiconductor power switching devices of the network bridge (14). In response to a change in wind speed (e.g. an increasing or decreasing wind speed) the method comprises the steps of: (i) controlling the second active rectifier/inverter (14) to change the level of power exported out of the dc link (12) such that the dc link voltage changes from a desired level, and (ii) controlling the first active rectifier/inverter (10) to import sufficient current into the dc link (12) through the generator bridge (10) from the generator (4) to restore the dc link voltage to the desired level.

Title: Method for quantitation of microorganism contamination of liquids and apparatus therefor
Inventor: KANE JEFFREY F
IPC: C12M1/34
Filed: 1997-07-25
Granted: 2000-11-22
Abstract: Use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and the like. The capsule allows a severe reduction in the water sample size tested, substantially minimizes risks of cross-contamination, and provides a leak-proof vessel for shipment. Risk of infection of laboratory personnel and time of analysis are both reduced. Costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.
