(under subclass 774) Subject matter wherein the workpiece support applies a force on the workpiece to keep the workpiece from moving about.
(1) Note. This subclass does not include heating apparatus wherein the heater and the work are brought into proper
relationship, the heat applied, and the heater and work then separated. In this subclass, the work must be moved with respect to the heater during the heating operation.
(2) Note. Means for molding, shaping, or metal working are excluded from this subclass. For such excluded subject matter see SEARCH THIS CLASS, SUBCLASS and SEARCH CLASS below.
