DEFINITION

Classification: 156/272.2

With direct application of electrical, magnetic, or radiant energy to work:

(under subclass 60) Processes which include the step of (a) passing an electric current directly through the work, (b) subjecting the work to a changing electric field, or (c) directly applying magnetic or radiant energy to the work.

(1) Note. Work is the object or material which results from, or is intended to be subjected to, an adhesive bonding.

(2) Note. The electrical energy or wave energy must act directly on the work and not, for example, by connection or conduction of heat from an element not constituting part of the work.

(3) Note. The wave energy applied to the work may be light, ultraviolet rays, infrared rays, X-rays, cathode rays and emanations of radioactive material by particle emission, electron bombardment, electromagnetic fields, and like sources.
