(under the class definition) Apparatus and corresponding methods wherein the agitation is effected by the introduction of a gas under pressure into contact with the material in the mixing chamber.
(1) Note. The injection of gas into a liquid must be primarily for agitating the liquid. If the primary purpose is to mix the gas with the liquid, placement will be in Class 261, and see note to that class below.
