Description:

In 1964 Fairbanks, Morse Inc. changed its name to Colt Industries.

Abstract:

The electronic measuring system includes a novel power supply which converts D.C. from a D.C. source to voltage pulses to drive a transducer. During intervals between transducer power pulses, an automatic drift compensation system stores an indication of system drift for use during a subsequent power pulse period. The system includes stability sensing means which render the system inoperative for measurement purposes when the signal from the measuring transducer is unstable. A plurality of sample measurement signals are taken and stored, and then passed through a programmable low pulse filter to accomplish a measurement. Thus each measurement is the result of a plurality of measurement cycles.
