DEFINITION

Classification: 264/1.36

Utilizing plasma, electric, electromagnetic, particulate, or wave energy:

(under subclass 1.1) Processes wherein plasma, electric, electromagnetic, particulate, or wave energy is used to treat or shape the optical article.

(1) Note. The energy used may be light, sonic, supersonic, ultrasonic, gamma rays, infrared rays, X-rays, etc. Particulate energy includes charged particles and atomic

emissions, such as alpha rays, beta rays, and neutrons. The mere use of magnetic force employed to maintain a preform in a selected position is not provided for here, for which see subclasses 275+ below.

(2) Note. The energy must be applied as such directly to the work. 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 below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

10, for processes of comminuting a liquid by electrical energy.

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

405+, for process including the application of electrical or wave energy to work in general. SEE OR SEARCH CLASS

156, Adhesive Bonding and Miscellaneous Chemical Manufacture,

272.2+, for a laminating process including direct application of electrical or radiant energy to the work, and see the SEARCH CLASS notes thereunder.

201, Distillation: Processes, Thermolytic,

5+, for a thermolytic distillation process combined with a shaping operation in which electrical energy is applied to the work; and subclass 19 for a thermolytic distillation process in which electrical energy is applied to the work.

204, Chemistry: Electrical and Wave Energy, appropriate subclasses for processes effecting a chemical reaction by utilizing electrical or wave 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.

520, Synthetic Resins or Natural Rubbers, particularly Class 522 for a process of preparing or treating a synthetic resin or natural rubber involving a chemical reaction brought about by application of wave energy.
