Abstract
Conventional mechanical positioning in which an input member is moved in a position field which is an enlarged representation of the output position field and conventional motorized positioning in which distance is represented by time of travel are modified and combined. The result is a method, and apparatus, in which movement but not position are represented mechanically on a field which represents any portion of the output field at which the output element is positioned. Input motion and direction are converted to digital or time duration signals. The result is apparent motion of the output element along whatever line is traversed mechanically by an input element. Input motion may be introduced at variable velocity. The input is introduced much as it is in a pantograph system but, unlike the pantograph system, the field of input motion is not a reproduction of the output motion field but represents, instead, any portion of the output field. That makes it possible to alter the ratio of input to output motion with ease.
