DEFINITION

Classification: 264/405

DIRECT APPLICATION OF ELECTRICAL OR WAVE ENERGY TO WORK (E.G., ELECTROMAGNETIC WAVE, PARTICULATE, MAGNETIC, INDUCTION HEAT, SONIC, ELECTROSTATIC ENERGY, ETC.):

(under the class definition) Processes directed to applying electrical, electromagnetic, magnetic, wave, or particulate energy directly to the work.

(1) Note. Some examples of wave energy found in this subclass are electromagnetic, particulate, light, sonic, supersonic, ultrasonic, gamma rays, X-rays, and magnetic energy. Particulate energy includes charged particles and atomic emissions, such as alpha rays, beta rays, and neutrons. Mere use of magnetic force employed to maintain a preform in a selected position is not provided for here, rather see subclasses 275+.

(2) Note. The energy must be applied as such to the work, the work precursor or the coating material used in a combined coating and shaping operation. Processes utilizing wave energy (e.g., plasma, etc.) to apply a coating combined with

a shaping operation are properly classified in this subclass and indented subclasses. Conversion of electrical energy to heat and the application of the heat to the work is excluded from this subclass and is provided for in appropriate subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

275+, for processes of molding wherein magnetic or electrostatic force is utilized to maintain a preform in a selected position during molding and see (1) Note, above.

SEE OR SEARCH CLASS

204, Chemistry: Electrical and Wave Energy, appropriate subclasses for a process of effecting a chemical reaction by utilizing electrical or wave energy, especially 157.15+, for a process of preparing a specific compound utilizing electrical or eave energy. The line stated in the Class 204 definition for claims defining a Class 204 operation combined with an operation for another class is to be followed for classification of claims defining both Class 204 and Class 264 operations.

522, Synthetic Resins or Natural Rubbers,

1+, for processes of preparing or treating a synthetic resin or natural rubber involving a chemical reaction brought about by the application of wave energy.
