(under subclass 326) Electrodes which are composed at one end of an unbaked material, the unbaked material being designed to be baked by heat applied to the electrode during the use of the electrode.
(1) Note. The heat to bake the electrode may be generated by a space discharge, or by the heat generated by the resistance to the passage of the current which flows from the end of the electrode to the lead-in conductor for the electrode.
(2) Note. With respect to the subject matter of this subclass, there is little distinction between the process of making the article and the process of using the article. Therefore, any claims relating to processes of making self-baking electrodes will be deemed to be directed to a process of using the same where the process includes the baking in the use of the electrode article. For classes which relate to processes of using self-baking electrodes, see the search notes below. Processes of using the electrodes are classified with the art to which the process relates.

204, Chemistry: Electrical and Wave Energy,
280+, for self-baking or Soederberg electrodes limited to use in electrolytic apparatus. Where the disclosure is that the electrode can be used in an electrolytic device and the claimed structure does not necessarily so limit the electrode to such use, the patent is classified in Class 313 and cross referenced to Class 204. 264, Plastic and Nonmetallic Article Shaping or Treating: Processes, appropriate subclasses, for processes within the class definition, for molding or shaping plastic materials, particularly
104+, and 614+ pertaining specifically to molding of electrical articles.
373, Industrial Electric Heating Furnaces,
89, and 97 for self-baking electrodes in electric furnaces.
445, Electric Lamp or Space Discharge Component or Device Manufacturing,
1+, and 60+ for Methods and Apparatus for the miscellaneous manufacture of electric light and space discharge devices and the electrodes therefor.
