A STUDY AND EVALUATION OF LIQUID-LEVEL AND LIQUID-VOLUME CONTROLS FOR SHELL-, ROCKET-, AND BOMB-FILLING MACHINES

Abstract

The latest improvements added to the weigh filler are described. These involve a rate circuit, and also a device which positions leaf springs so that they engage the shadograph lever arm as it moves away from balance. Tests of the filling system made f llowing the addition of these improvements showed that its accuracy was better than one per cent for 500gram fill and also for 1000-gram fill. Results of these checks are included. Drawings of the redesigned chamber release valve are presented.
