Class Information
Number: 366/262
Name: Agitating > Stirrer within stationary mixing chamber > Pump type
Description: Subject matter wherein a confined flow path within the mixing chamber forms part of the course through which material is caused to pass by means of a pump within the chamber which (a) directly forces or induces material through the flow path, or (b) causes the material to move to and fro in said path, thereby producing turbulence and agitation of the material in the chamber.
