DEFINITION

Classification: 239/654

(under subclass 650) Apparatus comprising a device which develops a gas flow or acts as a source of supply of gas, to mix with the material.

(1) Note. The current of gas may be applied to the material after it has been introduced into the ambient, may mingle with the material in the strewing means before it reaches the ambient, or may act as a fluid to entrain and transport the material to the ambient.

(2) Note. If the current of gas is applied to the material in the ambient, this is considered to be the strewing means required for this definition (see subclass 650); otherwise the strewing means must meet the requirement set out in (2) Note of subclass 650 in regard to either the rotary or nozzle type scatterer.

(3) Note. Included under this definition is a device comprising a single gas stream developing or source means discharging to a plurality of strewing means.

SEE OR SEARCH THIS CLASS, SUBCLASS:

77+, for an orchard type mobile duster comprising means to discharge a material into a stream of generated gaseous conveying current which carried the material onto a tree or trees.

SEE OR SEARCH CLASS 222, Dispensing,

617, and 630+ for a dispenser with fluid flow discharge and subclass 394 for a dispenser in which a fluid (i.e., discharge assistant) contacts the material to be dispensed and moves it toward the outlet.

366, Agitating,

101+, for gas effected mixing, per se.

406, Conveyors: Fluid Current, appropriate subclasses for fluid current conveyors, particularly

154+, for fluid current conveyor outlets. Generally, any structure recited in a claim that accomplishes scattering or spraying (e.g., specific nozzle structure or relative orientation of spaced outlets) should be considered for Class 239 rather than Class 406.

414, Material or Article Handling,

524, for a self-loading or unloading vehicle having a load handling means of the fluid current conveyor type.
