DEFINITION

Classification: 322/95

(under subclass 89) Subject matter wherein the generator armature control is by means of impedance in circuit with the armature.

(1) Note. See the class definition, especially sections I, D, for a statement as to other classes which provide for a generator supplied load circuit where the load circuit is controlled by an impedance.
