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

Abstract

The sequencing control equipment was constructed and installed in the constant-vol me munitionfilling device. This circuit provides automatic c ntrol of the entire filling- peration cycle. T e ervo otor drive that operates the Annin valve was modified, and its performance improved. The servomotor, gearbox, and rate generator have been mounted into a c mpact unit, providing precision operation and sturdy construction. Late delivery of Annin valve seats and plugs have delayed further tests of the entire munition-filling system. A preliminary model of the release valve for the weigh chamber was built; however, certain design improvements are necessary on this device.
