Abstract
The relative positions between a pair of moving objects and the velocity of one of such objects is controlled so as to synchronize the movements of the objects. Synchronization is achieved through the use of a novel sensor mechanism and a control circuit associated therewith. The sensor mechanism, which may be mounted on a molten metal pouring machine, includes a moving beam which carries a probe which describes the same circular arc regardless of where positioned on the beam. The probe contacts an object on a conveyor, for example a mold to be poured, and a signal generator mechanically coupled to the moving beam will provide an output signal commensurate with the relative position and velocity of the tool and workpiece.
