DEFINITION

Classification: 361/225

ELECTRIC CHARGING OF OBJECTS OR MATERIALS:

(under the class definition) Subject matter wherein a means or method is provided for imparting an electrical charge to a

material or object.

(1) Note. Where the charging of objects or materials is combined with the specific features of an art environment, the search should be made in the class which relates to the art environment.
