416003000 | ACTUATION DIRECTLY RESPONSIVE TO MAGNETIC OR ELECTRICAL EFFECT | 9 |
20110064575 | CEILING SWEEP FAN - A ceiling sweep fan comprising a rotor supported for axial rotation about upper and lower housings, the rotor supporting a plurality of radially extending fan blades, the upper housing and rotor enclosing an electric motor that drives the rotor; wherein the fan includes stop means to cause the rotor to stop at a fixed position relative to the upper and lower housings. | 03-17-2011 |
20110200434 | MAGNETIC MICROPARTICLE AND METHOD FOR MANUFACTURING SUCH A MICROPARTICLE - A microparticle includes an oblong flexible tail able to propel the microparticle in a solution along a trajectory using beats transverse to the trajectory, the tail including at least one magnetic element such that the magnetic element causes beats of the tail under the action of an external alternating magnetic field non-collinear with the trajectory and a head mechanically connected to a proximal end of the tail. The microparticle includes at least one layer of material formed from one piece and including the tail and the head, the dimensions and/or shape of the head being selected such that the beats of the proximal end of the tail are limited with respect to the beats of the distal end of the tail and such that the head does not perform a complete revolution around an axis parallel to the trajectory under the effect of the external alternating magnetic field. | 08-18-2011 |
20120070282 | High torque vertical axis windmill - A high torque vertical axis windmill that has blades with curved parts secured together. The second part of each blade is movable to deploy the maximum surface of the blade to the wind for maximum torque during a portion of the cycle of the blades. The second part of each blade is movable to a second position to deploy the minimum surface of the blade to the wind for minimum drag during another portion of the cycle of the blades. | 03-22-2012 |
20130039761 | VERTICAL WIND TURBINE WITH ARTICULATED BLADES - A vertical wind turbine to catch the wind force characterized by its system of aerodynamic panels are provided with blades fixed into horizontal axis that open and close simultaneously and symmetrically upward and downward due the gears like the butterfly wings rotated by 90° of its normal position, it is like opens an umbrella horizontally to receive on one side the wind buoyancy or pressure and in the other side close by the action of the wind. The top and bottom blades works as counterweight one to another both to open and close (flatness) which makes your weight null in relation to the effort of wind to open or close them independent of the self-weight of the blades what propitiate the maximum use of the wind force in the traction side without loss to the return of the blades to the traction position driving a vertical axis. | 02-14-2013 |
20130170985 | ELECTRICAL POWERED TAIL ROTOR OF A HELICOPTER - The invention is related to an electrical powered tail rotor ( | 07-04-2013 |
20140169966 | MAGNET CASE AND ROTOR INCORPORATING THE SAME - A magnet case for a rotor includes a hollow cylindrical supporting body for accommodating two magnetic bands, an annular flange extending outwardly from a top end of the supporting body, and a positioning plate extending inwardly from a bottom end of the supporting body. The annular flange of the magnet case has two spaced notches defined in an outer periphery thereof, and the two spaced notches are configured to reduce vibration of a cooling fan associated with the rotor during operation of the cooling fan. A rotor incorporating the magnet case is also provided. | 06-19-2014 |
20140193256 | WIND POWER GENERATION APPARATUS - There is provided a wind power generation apparatus capable of suppressing power consumption in an airflow generation device, and securely suppressing flow separation on a blade surface, thereby improving efficiency. A wind power generation apparatus | 07-10-2014 |
20140271190 | Wind Turbine Blade having a Conductive Root Bushing - A wind turbine blade is described having a lightning protection system wherein a lightning down conductor is conductively coupled to at least one blade root bushing provided at the root end of the blade. The use of the blade root bushing as part of the conductive path of the lightning protection system allows for a structurally sound and reliable connection of an internal down conductor to an external lightning protection system and/or to a suitable ground connection at the blade root end. | 09-18-2014 |
20160186570 | SUPERCONDUCTING POWER SHAFT CORE - A gas turbine turbine rotor(s) having a combination there of proximal embedded permanent magnets in the blended turbine(s) trunion structure to which blades are integral to and through these distal trunion channels attach, to which turbine blades are integral to as a single component, thereof exist permanent magnet) or in another embodiment warm conducting coils, or cold superconducting coils) levitating fields, rotating around a superconducting power shaft core (SPSC), running axially in relation to said turbine blade magnets and embedded distal trunion rings. | 06-30-2016 |
