DEFINITION

Classification: 422/129

CHEMICAL REACTOR:

(under the class definition) Apparatus for the formation of a product by chemical reaction not otherwise provided for.

SEE OR SEARCH THIS CLASS, SUBCLASS:

105+, for apparatus having means for automatically modifying an operation of the system in response to a means sensing an operating condition or change of the same; e.g., automatic shutdown of the reactor responsive to excessive temperature, pressure, etc.

SEE OR SEARCH CLASS

156, Adhesive Bonding and Miscellaneous Chemical Manufacture, appropriate subclasses for chemical manufacturing apparatus not elsewhere provided for producing articles of manufacture, and see especially

345, for differential etching apparatus.

196, Mineral Oils: Apparatus, appropriate subclasses for apparatus for treating mineral oils. Catalytic apparatus, even though employed for carrying out a catalytic-cracking process provided for in Class 208, Mineral Oils: Processes and Products, is classified in this class (422).

204, Chemistry: Electrical and Wave Energy, 193+, for apparatus employed in carrying out a process provided for in that class, which apparatus is not provided for in any other class.

250, Radiant Energy,

255, for apparatus for testing earth material samples involving, and in name only, chemical or physical separation and an invisible radiation test of the separated material; subclass 281 for ionic separation or analysis apparatus; subclasses 306+ for the inspection of solids or liquids by charged particles and the detection of the particles modified by the solids or liquids; subclasses 336.1+ for apparatus for

analyzing material.

260, Chemistry of Carbon Compounds, for organic compounds and process of manufacturing the same.

401, Coating Implements With Material Supply,

40+, and 44+ (particularly subclass 47) for a coating implement by means of which diverse materials are applied to a work surface.

423, Chemistry of Inorganic Compounds, for inorganic compound and nonmetallic elements and processes for their manufacture involving chemical reaction.

435, Chemistry: Molecular Biology and Microbiology,

283.1+, for apparatus for propagating, treating, or containing living organisms or for fermenting.
