DEFINITION

Classification: 239/310

(under subclass 302) Apparatus in which the holder contains material to be picked up in, to be commingled with, or to pass into solution with, a flowing nongaseous fluid stream.

(1) Note. This subclass provides the locus for patents claiming dissolving or mixing apparatus with a flow conductor attached spraying or sprinkling means (nozzle) disclosed for this class however claimed (by name only or specifically) and not provided for in the indented subclasses.

47, Plant Husbandry,

1.01, for apparatus adding fertilizer and the like to an irrigation stream. 137, Fluid Handling,

88+, for fluid handling involving mixture condition sensing and maintaining, subclass 268 for holders for solid, flaky or pulverized material to be dissolved or entrained, and subclasses 888+ and 896+ for multiple inlet and single outlet means for mixing, diffusing or injecting arrangements.

220, Receptacles, appropriate subclasses for shaving cups.

222, Dispensing,

630+, for fluid flow discharge means particularly for dry

powder having air current conveying means.

401, Coating Implements With Material Supply,

40+, and 44+, particularly subclass 47, wherein the implement includes means whereby material is picked up, commingled with, or dissolved by a liquid stream before being fed to the tool or applied directly to a work surface for treatment by a spreading tool.

406, Conveyors: Fluid Current,

108+, for feeders or intakes to fluid current conveyors, no scattering or spraying means being claimed subsequent to the conveyor.

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

261+, for apparatus for holding solids to be mixed or dissolved, which holding means as disclosed is incapable of retaining liquids, and claiming only so much fluid handling as is essential to the function of this operation.
