DEFINITION

Classification: 239/461

(under the class definition) Apparatus comprising means for (1) imparting a swirling or spinning (rotary or spiraling) motion to a flowing fluid in a fluid conductor prior to egress thereof, (2) smoothing out or quieting a turbulent or rotating flowing stream in a fluid conductor, or (3) redirecting and dispersing a flowing stream by some surface means positioned beyond the egress port or last point of fluid confinement and in a direct line therewith to accomplish an abrupt change in the direction of flow of the fluid.

(1) Note. Apparatus which is disclosed as a burner and which has a fluid redirecting or dispersing means disclosed as made of incandescent or radiant material to reignite a flame is excluded from Class 239 and will be found in Class 431, Combustion, if such redirecting or dispersing means is claimed, whether or not the flame is claimed; see (1) Note under subclass 128 and Lines With Other Classes of the class definition of this class (239) in reference to Class 431, Combustion.

(2) Note. Included under this definition is a deflector device, per se, which is disclosed as attachable to the outlet end of a flow pipe to redirect or disperse the fluid impinging thereon.

SEE OR SEARCH THIS CLASS, SUBCLASS:

150, for deflecting or dispersing means combined with vehicular means mounting a fluid supply.

399+, for whirler devices in combination with means combining separately supplied fluid streams.

439, for deflector and outlet forming means combined there classified.

552, for inserts placed at the terminus of a flow line to divide the effluent into a plurality of streams.

553+, 590+, for interior guides in terminal members which are similar in structure to those appearing herein but which are not disclosed as fluid rotation controlling or anti-turbulence devices.
