Abstract
1. Apparatus for deriving an electrical signal comprising, means for initially positioning a body along an axis including means for supporting said body so that said body is free to tilt and thereby depart from a position along said axis, means for rotating said body about said axis at a constant rotational velocity, thereby causing the body to exert a centrifugal force in a rotating radial line normal to said axis, and means responsive to variations in the force of said body along the said radial line of centrifugal force resulting from departure of said body from said position on said axis to provide an electrical signal with a periodicity equal to that of said rotation and variable in accordance with said force variations.
