DEFINITION

Classification: 392/386

Vaporizer:

(under subclass 200) Subject matter under Class 219, ... wherein the heating device is disclosed for use in converting a substance from a solid or liquid to a gaseous state.

38, Textiles: Ironing or Smoothing,

77.1+, for moistening means. 43, Fishing, Trapping, and Vermin Destroying,

125+, for vaporizers in fumigating apparatus.

62, Refrigeration,

50.1+, for liquified gas transferred as liquid.

68, Textiles: Fluid Treating Apparatus,

222, for steamers.

118, Coating Apparatus,

726+, for crucible.

122, Liquid Heaters and Vaporizers, appropriate subclasses for apparatus for generating vapors from liquids and further utilizing the vapors thus generated, e.g., steam generator. The structure found in this class is very similar to those found in Class 219, especially the so-called flashers in

40+, and wicks in subclass 366 which do not disclose an electrical heating means.

123, Internal-Combustion Engines,

543+, for charge forming devices involving vaporizers. 126, Stoves and Furnaces,

20, for steam or hot water; subclass 113 for air moisteners; and subclasses 369+ for steaming apparatus.

128, Surgery,

203.12+, for vaporizers for medicaments.

132, Toilet,

227+, for heater, fluid supply, or surrounding fluid housing and subclasses 272+ for vapor reservoir.

159, Concentrating Evaporators, appropriate subclasses for devices for the concentration of solids held in solution or suspension by evaporation.

196, Mineral Oils: Apparatus,

104+, for apparatus, for the distillation of mineral oils and, especially, subclass 121 for electric heating.

202, Distillation: Apparatus, appropriate subclasses for distillation apparatus in general.

203, Distillation: Processes, Separatory, appropriate subclasses for a process of distilling a liquid. 208, Mineral Oils: Processes and Products,

313, and 347+ for a process of distilling mineral oil.

210, Liquid Purification or Separation,

175+, for heater or heat exchange.

219, Electric Heating,

401, for ovens with steam generating means.

223, Apparel Apparatus,

51, for heating and steaming.

236, Automatic Temperature and Humidity Regulation,

44, for humidity control.

237, Heating Systems,

9, for steam and subclasses 16+ for combined radiator and boiler. 239, Fluid Sprinkling, Spraying, and Diffusing,

34+, for diffusers; subclasses 128+ for sprayers with means to generate a water vapor or steam; and subclasses 136+ for vapor generator.

252, Compositions,

67+, for specific compositions useful for vaporization purposes.

261, Gas and Liquid Contact Apparatus,

127+, for external supply or removal of heat and subclass 141 for electric heater.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing,

305, for fume generating apparatus and 292+ for sterilizers using steam.

431, Combustion,

13+, 208, and 258 for a fuel burner having an electrically heated fuel vaporizer.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, 1+, for continuous gas or vapor phase colloid system (e.g., smoke, fog, aerosol, cloud, mist) or agents for such systems or making or stabilizing such systems or agents, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.

607, Surgery: Light, Thermal, and Electrical Application,

81+, for bathing apparatus and subclasses 96+ for thermal applicators.
