110, Furnaces,

235+, for incinerators for refuse.

126, Stoves and Furnaces, 452, for the process of general heating using solar heat.

243+, particularly subclasses 292+ for treating a solid article or material with a "chemical" in a liquid, gaseous, or vapor state (e.g., steam sterilizers, steam is considered a "chemical" also when it disinfects, sterilizes, deodorizes, or preserves, since steam so used appears to have a function more than mere heating) wherein the article or material is recovered essentially unchanged from the treatment (a "chemical" is defined as a substance which has a function beyond that of another class, per se, e.g., drying, heating, cleaning, etc.; a recitation that a substance disinfects, sterilizes, deodorizes, or preserves will cause the substance to be considered a "chemical" unless accompanied by positive disclosure that the disinfecting, sterilizing, deodorizing, or preserving is done only by a function provided for elsewhere; e.g., heating, etc.), and subclasses 307+ for heat treating vessel with heating means, not elsewhere provided for.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

5, for means of encapsulating normally liquid material, subclasses 6+ for means of making particulate material directly from liquid or molten material, and subclasses 130+ for means of feeding fluent stock from plural sources to common shaping means to form composite product and the rest of the class for shaping of articles.
