DEFINITION

Classification: 73/863.43

Having precapture flow guide or homogenizer:

(under subclass 863.41) Subject matter including means for contacting the moving source material upstream from the capture element, the contacting means either rendering the flow pattern more uniform or changing the flow direction with respect to the capture element.

(1) Note. The contacting means can be a fluid current (e.g., compressed air).

(2) Note. Mere contact with a conduit or flow confining means through which the source flows in an undisturbed manner is not sufficient for classification herein.
