| 20080224349 | Methods for Manufacturing Multi-Layer Rotationally Molded Parts - This invention relates generally to methods of rotationally molding multi-layer parts. More particularly, in certain embodiments, the invention relates to methods of manufacturing a part having an interior layer of polymerized macrocyclic polyester oligomer and an exterior layer of a substantially non-oligomeric polymer. The invention also relates to methods of manufacturing a part with a scratch resistant surface. | 09-18-2008 |
| 20090192253 | RECYCLABLE TOOLING COMPOSITIONS AND METHODS OF THEIR MANUFACTURE AND USE - This invention relates generally to compositions of macrocyclic polyester oligomer (MPO), polycaprolactone, and a thermoplastic elastomer (TPE). More particularly, in certain embodiments, the invention relates to recyclable tooling compositions made from MPO, polycaprolactone, and a thermoplastic copolyester elastomer. | 07-30-2009 |
| 20100098541 | METHOD AND SYSTEM FOR OPERATING A WIND TURBINE GENERATOR - A method of operating a wind turbine generator having at least one wind turbine blade includes increasing a pitch angle of the at least one wind turbine blade as the at least one wind turbine blade rotates through a first range of blade azimuth values. Such increasing of the pitch angle reduces acoustic emissions generated by the wind turbine generator. The method also includes decreasing the pitch angle of the at least one wind turbine blade as the at least one wind turbine blade rotates through a second range of blade azimuth values. Such decreasing of the pitch angle increases electric power generated by the wind turbine generator. | 04-22-2010 |
| 20110135485 | SPAR FOR A WIND TURBINE ROTOR BLADE AND METHOD FOR FABRICATING THE SAME - A spar for a wind turbine rotor blade is provided. The spar includes a support member and a spar cap coupled to the support member. The spar cap includes a plurality of pultruded profile segments. | 06-09-2011 |
| 20110142623 | SYSTEM AND METHOD OF DISTRIBUTING AIR WITHIN A WIND TURBINE - An air distribution system for use with a wind turbine. The wind turbine includes a nacelle that is coupled to a tower and a rotor that is rotatably coupled to the nacelle with a rotor shaft. The rotor includes at least one rotor blade that is coupled to a hub. The air distribution system includes a conduit that is defined within the rotor shaft. The conduit provides flow communication between the nacelle and the rotor. An air-flow control assembly is coupled in flow communication with the conduit. The air-flow control assembly is configured to selectively channel air from the nacelle to the rotor and from the nacelle to ambient air. | 06-16-2011 |
| 20110142638 | WIND TURBINE ROTOR BLADE WITH ACTUATABLE AIRFOIL PASSAGES - A wind turbine rotor blade includes a pressure side and a suction side. At least one airfoil passage is defined through the blade between the pressure side and suction side. A respective cover is configured over the airfoil passage at each of the pressure and suction sides. The covers are actuatable between a closed position wherein the cover is flush with the respective pressure or suction side and an open position wherein the cover moves to open the airfoil passage. | 06-16-2011 |
| 20110142642 | WIND TURBINE ROTOR BLADE WITH AERODYNAMIC WINGLET - A wind turbine includes a plurality of rotor blades, with each blade having a root portion connected to a rotor hub and an airfoil portion extending radially outward from the rotor hub. The airfoil portion further includes a main foil section and a winglet pivotally connected to the main foil section so as to pivot from an in-line position wherein the rotor blade has a first sweep length to an articulated position wherein the rotor blade has a second sweep length. In the articulated position, the winglet may pivot to not more than 90 degrees relative to a longitudinal axis of the main foil section. A deployable sleeve may be connected to the winglet so as to extend between the winglet and the main foil section in the articulated position of the winglet. The sleeve is stowable within either or both of the main foil section or the winglet in the in-line position of the winglet. | 06-16-2011 |
| 20110142677 | WINGLET FOR WIND TURBINE ROTOR BLADE - A rotor blade for a wind turbine is disclosed. The rotor blade includes a root, a tip, and a body extending from the root, the body including a pressure side and a suction side extending between a leading edge and a trailing edge. The rotor blade further includes a winglet extending between the body and the tip, the winglet including a pressure side and a suction side extending between a leading edge and a trailing edge. The winglet further includes a transition section and defines a height, a sweep angle, an outboard cant angle, and a twist angle. The sweep angle, the outboard cant angle, and the twist angle change continuously throughout the transition section. | 06-16-2011 |
