Abstract: A wind turbine rotor speed control for ensuring a constant rotational speed within tight tolerances includes a self-sufficient rotor (16) incorporating aerodynamic and mechanical devices to provide the control. There is a fixed turbine blade (26) adapted to be mounted on a shaft (14) for rotation therewith, the fixed blade (26) having pivotal blade tips (28) at its respective ends. The pitch control of the blade tips regulates the rotor speed. Aerodynamic tabs (180) are pivotally secured adjacent each of the ends of the respective trailing edges (34, 36) of the fixed blade. The relative wind acts on each tab which is connected to a series of links (188-168) and pitch cams (86) to regulate the pitch of the blade tips from a feathered position (210), to a cut-in position (212), to a rated wind position, and vice-versa.

Abstract: What follows is a description of a mechanism for displacing structurally related component parts of a larger assembly of parts relative to each other. The component parts are typically locked together into the larger assembly and the mechanism is designed to first unlock the component parts and thereafter produce the relative displacement of the component parts. The mechanism is also designed to reverse the noted procedure and first produce the relative displacement followed by locking of the component parts. The procedure is effected using a single actuator and a continuous operation.
