DEFINITION

Classification: 366/76.1

With specified feed means:

(under subclass 69) Subject matter including a particularly described means for conveying or admitting material into said mixing chamber.

(1) Note. Mere recitation of an opening, inlet port, or feed conduit for the material will not be considered specified feed means. However, any of the following claimed particulars will be considered specified means for this subclass: (a) Means applying positive or negative pressure on material to move it into the chamber (e.g., pump). (b) Conveyor means (e.g., belt, screw, chute). (c) Feed control means (e.g., valve, gate). (d) Structure determining the proportions of different material fed to the chamber. (e) A feed conduit extending into the mixing chamber or in tangential relation to the chamber. (f) A plurality of feeders (conduits, chutes, hoppers, etc.) in a particular relation to each other and/or to the mixing chamber. (g) A supply reservoir and means to feed material from the reservoir into the chamber.
