SEE OR SEARCH CLASS

110, Furnaces, for solid fuel burners, per se, and particularly

260+, for torches which burn both solid and liquid fuels.

148, Metal Treatment, appropriate subclasses for processes of chemical-heat removing (e.g., flame cutting, etc.) or burning (i.e., oxidizing) of a metal workpiece.

175, Boring or Penetrating the Earth,

11+, for a process or means for forming a hole in the earth by directly applying heat to fluidize or comminute the material forming the earth, and particularly subclass 14 for such process or apparatus in which the heat is produced by combustion in a confined chamber having a restricted orifice. 228, Metal Fusion Bonding, appropriate subclass, for welding apparatus which apply heat to the members to be bonded together.

239, Fluid Sprinkling, Spraying, and Diffusing, appropriate subclass, for tips or nozzles which dispense combustibles where no feature or structure is recited which specializes the tip for cutting or burning.

431, Combustion, appropriate subclass, for a residual fuel burner, per se.
