ABSTRACT:
The movement of a template past a stylus is controlled by furnishing desi velocity signals to first and second motors driving the template along two mutually perpendicular axes. Two wheatstone bridge strain gauge arrangements, one for each axis, and energized by quadrature voltages furnish signals which are combined in a summing amplifier to yield a signal having an amplitude and angular deflection corresponding to that of the stylus. The signal is rectified yielding a signal corresponding to the amplitude of stylus deflection and is further used to synchronize a sawtooth wave generator in accordance with the angle of deflection. The sawtooth wave output and the amplitude signal output are compared and when equal set a monostable multivibrator which closes two switches each sampling the output of one of the quadrature voltage generators energizing the strain gauges. Each of the so sampled voltages is applied to a potentiometer the output of which controls a corresponding one of the drive motors for the template.
