| 416246000 | Selectively adjustable impeller mount | 10 |
| 20100226787 | FAN ASSEMBLY - A fan assembly for creating an air current includes an air outlet mounted on a stand. The stand includes a base and a body tiltable relative to the base. Each of the base and the body has an outer surface shaped so that adjoining portions of the outer surfaces are substantially flush when the body is in the untilted position. | 09-09-2010 |
| 20100232977 | Height Adjustable Wind Turbine Nacelle - A nacelle for a wind turbine, which nacelle has a height in its installed position, comprising a bottom part having a bottom face and two opposite side faces defining a space between the bottom and side faces and the bottom part width and a top part having a top face. Together, the faces define a nacelle cover within which wind turbine components can be housed. The nacelle cover has two intermediate parts intermediate the side faces and the top face. The invention also relates to a replacement kit and a replacement method. | 09-16-2010 |
| 20100278658 | ELECTRIC FAN - An electric fan has a driving assembly, a stand and an impeller assembly being connected to and being driven by the driving assembly. The driving assembly has a positioning panel having multiple indentations and two connectors being formed on the positioning panel. The stand is mounted into the driving assembly and around the connector of the driving assembly and has at least two resilient positioning protrusions engage two of the indentations of the driving assembly. With the at least two positioning protrusions engaging different indentations, the driving assembly and the impeller assembly are pivoted and are held in different angles. Therefore, the angle of the impeller assembly is easily adjusted. | 11-04-2010 |
| 20100316501 | OMNI-DIRECTIONAL FAN DEVICE - An omni-directional air flow device, for example, a fan or a vent associated with a fan, comprises a swivel control point providing almost a spherical range of motion of the air flow device so that air may flow in any direction. The omni-directional air flow device may comprise a user input device for receiving a program for controlling movement of the air flow device through a pre-determined path within the spherical range of motion and for controlling air flow velocity as the air flow device follows the pre-determined path. Moreover, the device may further comprise a controller and memory for storing data representing the pre-determined path and varying air flow velocities along the path. When provided with temperature and humidity sensors coupled to the processor, the processor may calculate a comfort index and adjust the pre-determined path or air flow velocity accordingly. Links between the sensors and the processor, the swivel point and the processor and the user input device and the processor may be wireless. | 12-16-2010 |
| 20110020136 | BLADE PITCH-ANGLE CONTROL APPARATUS AND WIND TURBINE GENERATOR - A blade pitch-angle control apparatus is provided which can reduce the number of machining processes required for manufacturing a hub and which improves the maintainability due to a reduction in weight of each of hydraulic cylinders. The blade pitch-angle control apparatus, which is used in a wind turbine generator having a plurality of blades and which individually operates the pitch angle of each of the blades, uses the two hydraulic cylinders to operate each of the blades. | 01-27-2011 |
| 20110229342 | STOW ABORT MECHANISM FOR A RAM AIR TURBINE - A disclosed ram air turbine assembly includes a movable support structure that is prevented from moving to a stowed position by a stow abort mechanism that prevents movement to the stowed position when the turbine is not in a desired orientation. | 09-22-2011 |
| 20110236218 | HYBRID RAM AIR TURBINE - An example a ram air turbine assembly (RAT) is mounted to an airframe and provides both electric power and hydraulic pressure. A turbine drives a drive shaft about an axis transverse to rotation of the turbine. The drive shaft in turn drives both a generator and a hydraulic pump at a common speed. | 09-29-2011 |
| 20110299998 | HORIZONTAL AXIS WIND TURBINE - This horizontal axis wind turbine comprises a plurality of yaw motors that are provided on one of either a nacelle or a tower, and a gear | 12-08-2011 |
| 20140294596 | WIND TURBINE DEFENSE - Embodiments of the invention provide a number of passive and active defense designs and methods that enable a wind turbine to escape high wind events. The disclosure includes descriptions of multiple designs and methods for lowering the elevated portion of a wind turbine. Other embodiments of the invention concern ways to connect the elevated portion of a wind turbine to the tower. Numerous counterweight systems are also disclosed which enable the lowering of the elevated portion of the wind turbine. | 10-02-2014 |
| 20150017017 | Ceiling Fan Tilt Bracket - An apparatus that is used to tilt a ceiling fan such that the air flow of the ceiling fan is redirected. The apparatus mainly consists of a first mounting piece, a second mounting piece, and an adjustment bolt. The first mounting piece and the second mounting piece surround the down tube extending downward from a ceiling fan canopy bracket. The first mounting piece and the second mounting piece are attached together with a pair of patterned bolts. When in use, a user pushes the ceiling fan in a desired direction and tightens the adjustment bolt such that it makes contact with the ceiling fan canopy bracket. In another version, the apparatus can be controlled remotely. In doing so, servos or any other comparable means can be incorporated to control the adjustment bolt. The servos can be controlled by a smart phone or similar means. | 01-15-2015 |
