DEFINITION

Classification: 96/265

Including means to control contact liquid return flow to supply or sump:

(under subclass 243) Apparatus having (1) manual or power operated means (e.g., pump, etc.) located at some point in a contact liquid recirculation system for recirculating at least a portion of the contact liquid back to the point of initial use, or (2) means to drain, control the flow of, or send back the contact liquid to a liquid bath or reservoir spaced apart from the contact zone.

(1) Note. Mere mention of a recirculation line without positive recitation of control by pumping or restriction in the line is insufficient to cause a patent to be placed here.
