Abstract:
1. An apparatus comprising: a frame; a shuttle carried by the frame; a rotatable permanent magnet carried by the frame and having a north pole and an opposing south pole aligned with a plane, the rotatable permanent magnet rotatable about an axis within the plane and between the opposing poles; means confining the shuttle to a linear reciprocating movement generally parallel to the axis; first and second fixed permanent magnets fitted to the shuttle with the rotatable permanent magnet positioned between the first and second fixed permanent magnets, and with each of the first and second fixed permanent magnets having a north pole and an opposing south pole with an axis extending therebetween; and wherein the fixed permanent magnets are positioned on the shuttle such that rotation of the rotatable permanent magnet is coincident with a repelling force and an attracting force of the first and second fixed permanent magnets to effectuate the linear reciprocating movement of the shuttle.
