20110138949 | Linear Actuator with Ball Bearing Spline - A linear actuator includes a ball screw, the ball screw configured to rotate; a nut engaged with the ball screw, the nut configured to translate linearly in response to the rotation of the ball screw; and a ball bearing spline integrated into the nut, the ball bearing spline comprising a plurality of ball bearings, wherein the ball bearing spline is configured to react a torque from the rotation of the ball screw. A ball bearing spline is integrated into a translating nut of a linear actuator, the ball bearing spline comprising a plurality of ball bearings, wherein the ball bearing spline is configured to react a torque from a rotation of a ball screw engaged with the translating nut. | 06-16-2011 |

20130156596 | Airfoil Design for Wakeless Wind Turbine Tower Structures - A novel wind turbine is provided that reduces or eliminates aerodynamic wake downwind of the tower to allow for the wind turbine to face away from the direction of the wind. The wind turbine comprises a tower and a rotor rotatably mounted to a nacelle which is mounted to the tower in stationary relationship therewith. The tower has a yaw bearing at its base so that it is rotatable about a vertical axis. In one embodiment the tower comprises a single airfoil symmetric about its major chord. In another embodiment the tower comprises a pair of spaced apart asymmetric airfoils defining a nozzle-like space there between through which a relatively high speed jet of air can travel to fill the aerodynamic wake zone behind the tower. | 06-20-2013 |

20120308386 | Chain Drive Train for a Wind Turbine - A distributed chain drive train for a wind turbine is disclosed. The chain drive train may include a first stage chain drive adapted to receive mechanical energy from a main shaft of a wind turbine and a second stage chain drive adapted to receive rotational energy from the first stage chain drive and transmitting the rotational energy to one or more generators of the wind turbine. The chain drives are resilient to structural deflections that may misalign the sprockets and chains, resulting in a long lasting system. | 12-06-2012 |
