Abstract

Abstract This disclosure relates to a computer for determining the length of material required in order to arrest a moving strip of material in a preselected deceleration time, the material being payed out from a reel in a mill operated at a predetermined mill speed. An analog signal, which is a function of the mill speed and deceleration time, is applied to a voltage comparator. Another input to the voltage comparator is a ramp signal. A train of pulses, synchronized with the ramp signal, is generated as a function of the payed out length of the strip material, the pulses being counted by a stop length counter. When the voltage comparator has inputs which are equal in magnitude, an inhibit signal is developed which is applied to inactivate the stop length counter, the cumulative counts of which will then be a function of the length of material required to stop the mill for the mill speed and deceleration time selected by the mill operator.
