300.~.~ Utilizing direct application of magnetic, electrical, or wave energy

DEFINITION

Classification: 523/300

Utilizing direct application of magnetic, electrical, or wave energy:

(under subclass 1) Process wherein a desired or intentional composition is prepared utilizing a step of directly applying magnetic, electrical, or other wave energy, including wave energy produced by the decay of radioactive isotopes or by impact of a beam of highly energetic particles or the impact of a laser beam.

(1) Note. The energy employed must be applied directly to the intentional composition or to an ingredient of said composition.

(2) Note. When the energy is not applied directly but is used to generate heat or other kinetic energy which is transferred to the desired composition or its ingredients, then search the appropriate subclasses hereinbelow.

(3) Note. Sonic and ultrasonic wave energy are included herein.
