  • Patent number: 11441538
    Abstract: A wind turbine includes a tower, an aerodynamic rotor operable at a variable rotor speed and having a plurality of rotor blades each having an adjustable rotor blade setting angle and a generator for generating an electrical output power. An operating characteristic curve is prespecified for operating the wind turbine. The operating characteristic curve indicates a relationship between the rotor speed and the output power. A controller is provided, which sets the output power in accordance with the operating characteristic curve depending on the rotor speed. The the operating characteristic curve has a starting rotation speed to which the rotor speed increases as soon as the wind turbine starts when a sufficient wind speed is reached. The starting rotation speed is defined depending on a tower natural frequency of the wind turbine and/or depending on a detected turbulence measure of the prevailing wind.

  • Publication number: 20070023606
    Abstract: A clamp actuator engages a moving jaw at one end of a sliding bar. A fixed jaw is immovably mounted in opposition to the moving jaw. A lever presses a drive gate against the bar to move it forward with each stroke of the lever. Clamping surfaces are vertically staggered and engage a tree trunk or similar workpiece to clamp it in place. The action is horizontal so as to avoid interference with workpiece elements above the clamp. The clamp may be established within a basin or bowl containing water so as to accommodate a Christmas tree.
