ABSTRACT:
Two phases of weight or mass of equal value are interconnected at a fixed distance which rotate and interact with a force retainer having a circular path. Both phases move equally but in opposite direction from the center of rotation on a guide. The guide is connected at its linear mid point to a shaft that is supported in rotation by sleeves or bearings that are firmly attached to a frame. The force retainer is also attached to the frame. The combination allows the shaft to be rotated at a frequency that causes a centrifugal force to act upon the phases. The phases interact with the circular path through rollers forcing the phase radius to change from a normal orbit of equal radius. This causes an imbalance of centrifugal forces acting on the phases. The difference between the two centrifugal forces is transmitted to the frame through the phase rollers interacting with the circular path of the force retainer. The magnitude of centrifugal force of the phases are dependent upon frequency. The force applied to the frame is a vector equal to the greater of two centrifugal forces. Multiple guides with interconnected phase pairs can be used on a single shaft to produce more uniform resultant force vectors. Multiple shafts with one or more guides and phase pairs can be used on a single frame to increase the magnitude of the resultant force.
