    Abstract: A permanent magnetic top is arranged to rotate on one or more surfaces, of a toy induction turret, which are in close proximity to a coil. An electric circuit is arranged to switch the coil in such a manner so as to accelerate the top. A handle is connected to the turret so that the top may be skillfully transferred from one surface to another.

  • Patent number: 4525124
    Abstract: Curved airfoils are mounted on members attached to a vertical shaft. The ends of the airfoils point outward from the shaft. The members are attached to the upper and lower sections of the airfoils and converge as they approach the shaft. This minimizes the shaft length above the turbines upper most bearing and provides a balanced condition that distributes forces in such a manner which reduces airfoil stress.
