DEFINITION

Classification: 318/580

(under subclass 560) Subject matter in which the servomechanism guides a vehicle about a single axis, wherein the novelty is chiefly in the servomechanism and not in the guidance system.

(1) Note. The systems classified hereunder specifically exclude multiple axes vehicle guidance systems, which systems are classified in Class 244, Aeronautics, subclass 77, which subclass is the generic place for steering of dirigible craft in two or three dimensions by electrical means. See particularly (2) Note of Class 244, subclass 77, as to the line between subclass 77 and the other motor and vehicle classes.
