DEFINITION

Classification: 209/719

Tangential:

(under subclass 717) Methods and apparatus provided with a connection tangent to the separation device for directing the gaseous suspension into the separation device.

(1) Note. A nominal recitation of tangential infeed is sufficient for classification in this subclass.
