Use of a Servo System for Automatic Operation of the Fibrograph

Abstract

A simple method, which requires virtually no change in the Fibrograph, is described for converting the instrument to automatic operation by the use of a servo system. The accessories required are rugged and are commercially available. Smoother fibrogram curves are obtained by this method, and less time is required because the operator is free to comb the next test sample while a fibrogram curve is being drawn.
