WIND MOTORS [2013‑01]
NOTE

  • In this subclass, the following words are used with the meanings indicated:
    • "Wind motor" means a mechanism for converting the energy of natural wind into useful mechanical power, and the transmission of such power to its point of use;
    • "Rotor" means the wind-engaging parts of the wind motor and the rotary member carrying them;
    • "Rotations axis" means the axis of rotation of the rotor.
