DEFINITION

Classification: 164/48

(under subclass 47) Process wherein an energy quantity is applied directly to the work material as (1) an electromagnetic wave which is included in the frequency spectrum including and above audio frequency range (i.e., 50 cps), (2) an electric field or force or (3) an explosive force.

(1) Note. Included are such electromagnetic waves as radio, infrared, light, ultraviolet and gamma rays.

(2) Note. Application of sonic and supersonic wave energy are included herein. The mere application of vibratory or oscillatory forces without effecting transmission of wave energy, e.g, subsonic, are provided for below on other features.

(3) Note. For radiant energy to be included herein, it must be specifically claimed.
