DEFINITION

Classification: 361/230

ELECTRIC CHARGE GENERATING OR CONDUCTING MEANS (E.G., CHARGING OF GASES):

(under the class definition) Subject matter relating to corona or ion generators which utilize air or other gases as the charge generating medium to be placed in contact with the charge generating electrodes or with the specific electrodes which project the electric field generated.

(1) Note. This subclass also provides for other electric charge generating or conducting means not elsewhere provided for.
