DEFINITION

Classification: 366/169.1

Fed through stirrer or stirrer drive shaft:

(under subclass 168.1) Subject matter wherein the passage-forming element is an integral part of the stirrer.

(1) Note. A drive shaft integral with a stirrer is considered a part of the stirrer.

(2) Note. Typical of patents in this subclass is a stirrer having a drive shaft and having a passage in the shaft through which liquid is fed into the mixing chamber.

(3) Note. Substantially all of the material that flows through the passage-forming element must be from outside the mixing chamber rather than from the agitated contents of the mixing chamber.

164.2+, for apparatus in which material is fed into a mixing chamber through a stirrer or a conduit integral therewith by suction generated by the stirrer.
