Filed:

May 14, 2010

Appl. No.:

12/662983

Inventors:

Richard Stone - Teaneck NJ, US

Assignee:

Challenger Design, LLC - Hasbrouk Heights NJ

International Classification:

F03D 9/00
H02P 9/04
F01C 13/00
F01D 15/10

US Classification:

290 55, 290 4 R, 290 44

Abstract:

An auxiliary drive/brake system for a wind turbine includes an impulse, high torque motor, a gearbox transmission, a drive shaft, and a transfer gearbox that connects to either the wind turbine low-speed shaft or to the wind turbine gearbox. Control of the auxiliary drive/brake system is performed by a programmable computer-based motor drive control system in combination with instrumentation and sensors fitted to the rotating wind turbine components. Torque and horsepower created by the present auxiliary drive/brake system is transferred into the wind turbine low-speed shaft where it combines with the torque and horsepower created by the wind acting on the wind turbine rotor blades, the combined torque and horsepower is transferred from the wind turbine low-speed shaft into the wind turbine gearbox and the wind turbine generator, causing the wind turbine generator to operate and produce electricity which is supplied to the power company.

Richard Brian Stone - Teaneck NJ, US

Assignee:

ALSTOM Technology Ltd - Baden

International Classification:

B02C 15/00

US Classification:

241121

Abstract:

A pulverizer includes a journal assembly with a grinding roller that grinds solids in a grinding table. The oscillations of the journal assembly are monitored by an angular displacement transducer (ADT) that creates a composite signal. A controller receives the composite signal from the ADT and compares it with known information of the pulverizer. It then identifies abnormal situations such as damage to a grinding roll , the grinding table , the spring assembly and other parts of the pulverizer before they cause major damage.

Abstract:

An auxiliary drive/brake system for a wind turbine. The auxiliary drive/brake system includes an impulse, high torque electric motor connected to a motor drive control system which controls the impulse high torque electric motor. The auxiliary drive/brake system further includes a gearbox transmission, a drive shaft, and a transfer gearbox that connects to either the wind turbine low-speed shaft or to the wind turbine gearbox. The drive system provides impulse operation of the wind turbine. Control of the auxiliary drive/brake system is performed by an electronic speed control in combination with either a motor drive control system or an electronic variable speed drive. Torque and horsepower created by the present auxiliary drive/brake system is transferred into the wind turbine low-speed shaft where it combines with the torque and horsepower created by the wind acting on the wind turbine rotor blades, the combined torque and horsepower is transferred from the wind turbine low-speed shaft into the wind turbine gearbox and the wind turbine generator, causing the wind turbine generator to operate and produce electricity which is supplied to the power company.

Inventors:

Richard B. Stone - Teaneck NJ

Assignee:

Combustion Engineering, Inc. - Windsor CT

International Classification:

G01F 1110

US Classification:

222368

Abstract:

A suction type coal feeder provided with a rear cleanout opening normally closed by a pivotally mounted cleanout door. A quick release mechanism normally clamps the door in its closed position with this mechanism including a pair of brackets mounted on each side of the housing of the feeder. These brackets are secured in place by the mounting bolts for the feed roll plugs that form a part of the feeder and are located at each end of the feed roll that is mounted at this rear portion of the feeder. Studs extend from these brackets in a rearward direction and a clamp bar is pivotally mounted on one of these studs and extends to the other stud which is received in an upwardly extending slot in the clamp bar. The position of the clamp bar is such that it extends across the upper region of the cleanout door and is effective to clamp the door closed by means of handle nuts threaded onto the studs. Loosening of the nuts permits the pivotal removal of the clamp bar and opening of the cleanout door.
