<p>An apparatus and method for imparting an angularly rotational movement. The apparatus includes a cylinder having an internal portion, a rod operatively positioned within the internal portion of the cylinder, a first bearing operatively positioned about rod; a second unidirectional bearing operatively positioned about the rod and a motion program for selectively inputting incremental radial motion to the rod. The apparatus may also include a force generator for linearly moving the rod in a linear axial motion along an axis of the cylinder.</p> |
