DEFINITION

Classification: 239/398

(under the class definition) Apparatus having means for plural fluids to commingle upstream of, downstream of, or at the terminus.

SEE OR SEARCH THIS CLASS, SUBCLASS:

8+, for a method of distributing fluid including mixing with air, gas or steam.

77+, for fluid sprayed into a gaseous conveying current.

137+, for plural fluid supply means for mixing or entraining involving a heating means.

265.17, for a reaction motor discharge nozzle having means to add a secondary fluid to the main discharge stream upstream of the nozzle outlet.

290+, for apparatus involving supplemental gas shaping or shielding jets. 302+, appropriate subclasses for supply holding or containing means which additionally involve the combining of several fluids for purposes of blending, dissolving, or entraining one in another.
