DEFINITION

Classification: 219/647

With workpiece support:

(under subclass 600) Subject matter wherein a material or an object is contained in, held in place by, or set to rest upon an arrangement during inductive heating.

(1) Note. The meaning of "workpiece" is any object or material that work (in the form of heat) is applied to.

(2) Note. An inductor of the heating device may constitute the support.
