DEFINITION

Classification: 425/174

(under the class definition) Apparatus including means subjecting work to the influence of electrical, wave, or radiant energy by (1) means passing such energy through the work, (2) means establishing an energy field and positioning work therein or (3) means directing such energy against the work.

(1) Note. To be included herein under part (3) of the definition the type of radiant or wave energy employed must be specified either by wave length or specific type, e.g.., sonic ultra violet, corona discharge, etc.. Generic terms such as heat, light, wave, etc.., are not considered specified types within the scope of this subclass.

(2) Note. In all cases, the energy form employed must be applied directly to the work. Means converting energy into heat, for example, then applying the heat to the work is not included herein but found in appropriate subclasses below.
