.~ Including means to establish an electric space discharge
DEFINITION
Classification: 445/72
Including means to establish an electric space discharge:
(under subclass 60) Apparatus including means to set up or have an electric current flow between two spaced parts or electrodes, at least part of the path followed by the current flow being within a vacuum or a fluent media.
(1) Note. Means for establishing a space discharge solely to evacuate the space will be found in subclasses 70 and 73.
(2) Note. The discharge may be between electrodes other than the discharge electrodes, or between any other electrodes or parts capable of being used to establish an electric space discharge.

148, Metal Treatment, appropriate subclasses for processes of treating metal to modify or maintain the internal physical structure (i.e., microstructure) or chemical properties of metal. If metal casting, fusion bonding, machining, or
working is involved, there is a requirement of significant heat treatment as described in section III, A, of the Class 148 definition. Use of electric heating including space discharge does not negate placement in Class 148 if the other criteria for Class 148 are met. 204, Chemistry: Electrical and Wave Energy,
