Abstract: Disclosed herein is a radiation gauge equipped with a strip chart recorder for measuring the properties of moving materials. The recorder has a multiplicity of scales with selectively illuminated scale numerals, a measuring pen and pointer, and a specification target marking pen and pointer. The gauge includes a digital setup arrangement which receives decimal input numbers, indicative of the specification target value for the material to be measured and its composition, either from decimally numbered dials on the operator''s control panel, or from some other input device. Digital logic circuits responsive to the input numbers automatically select the proper scale to be used and illuminate the proper scale numbers. The logic circuits use both the specification target numbers and the composition numbers to automatically and digitally select the center scale and span settings which properly calibrate the gauge for the material to be measured. The logic circuits further use these input numbers to control a digital to analog converter servomechanism which drives the specification target pen and pointer. The operation of this converter is automatically sequenced to mark successively on the moving recorder chart lines whose positions identify the scale used, the material composition measured and the specification target value. The final position of the target pen and pointer determines the set point for an automatic controller for the process machine which produces the measured material.

Abstract: A system for computing total conditioned weight of a fiber sheet during manufacture responds to signals derived from moisture and basis weight gauges, a well as indications of suppressed zero value for basis weight and a conditioned weight factor. The signals and indications are combined in accordance with: Delta CW Kcw(BWs+ Delta BW) (1- M) - (BWs+ Delta BW)M+ Delta BW (a), WHERE: Delta CW the total conditioned weight deviation from a suppressed zero basis weight value; Kcw conditioned weight factor; BWs suppressed basis weight value; Delta BW basis weight gauge output, as a deviation of basis weight from suppressed zero basis weight value; and M moisture percentage of total weight as derived from a moisture gauge.
