DEFINITION

Classification: 156/379.6

With means applying wave energy or electrical energy directly to work:

(under subclass 349) Apparatus including mechanism to treat the work with electrical or electrostatic wave energy.

(1) Note. The energy must directly contact and treat the

work in the form of waves, rather than be converted to some other form of energy and then be directed against the work. Thus, resistance heating of work by including it as part of an electric circuit and passing current therethrough is here, but using a separate resistance heater and applying the generated heat to the work by conduction is excluded.

(2) Note. Mere heating of work by conduction or convection is not wave energy for the purpose of this subclass.

(3) Note. The energy may be applied to the work, for example, in the form of infrared rays, X-rays, a magnetic field, etc..

(4) Note. Except for those patents included in subclasses 379.7 and 379.8, the apparatus included herein is structurally of general utility for heating, pressing, molding, etc.., but is intended for use in laminating. For a complete search, the classes and subclasses which provide for the proximate function of the claimed structure need to be consulted.
