A Height Data Smoothing Mechanism

Abstract : A description is given of a height data smoothing mechanism, illustrated by a schematic diagram. The discontinuous height data is fed into the input shaft at intervals. This drives a differential, connected also to the ball carriage and roller of an integrator whose disk is turned by a constant speed motor. A correcting handwheel and the integrator feed another differential whose output of the device. The output and the input of the machine are compared through a differential feeding dial, and the operator is supposed to turn the handwheel in such a way that the positive and negative oscillations of the dial about zero are equal.
