(under the class definition) Processes which include removing material from the work, which removal comprises melting the material to be removed while it is on the work.
(1) Note. This subclass does not have the emptying of receptacles by melting of the contents, for which see the appropriate other classes as set forth in the notes below. It does, however, have the removal of solid residues adhering to the walls of containers, or adhering to other surfaces by processes including melting.
