DEFINITION

Classification: 156/273.9

Work constitutes conductor or electrical circuit:

(under subclass 272.2) Processes wherein at least a portion of the work after final assembly is a conductor which is to be used as a component of an electric circuit to which an electric current is to be directly applied.

(1) Note. This subclass includes subjecting metal work to an electric field which causes a current to be developed within the work, thereby resulting in heating of the metal work.

47+, for processes of making running or indefinite length electrical conductors.

272.2, and 275.1 - 275.7, and other appropriate subclasses for a process of adhesive bonding which includes subjecting metal work to a radiant or magnetic field.
