DEFINITION

Classification: 222/282

(under subclass 251) Dispensers having means to vary the output (discharge volume) from the discharge assistant for a given cycle of operation.

SEE OR SEARCH THIS CLASS, SUBCLASS:

14+, especially subclass 21, for preset means for selective dispensing of different volumes from a dispenser.

134, for dispenser involving plural sources and having interconnected discharge volume varying means.

163, for supply receptacles mounted for motion for discharge volume varying purposes.

250, for dispensers having a floating piston with plural or alternate discharge paths and discharge volume varying means.

266, where there are plural discharge assistants arranged in sets and discharge volume is varied by selecting less than all for discharge. 267+, where there are plural discharge assistants arranged in sets with common discharge volume varying means.

278, for plural alternatively usable discharge assistants which may discharge different volumes.

434+, for trap chamber cutoff combinations with discharge volume varying means, the trap chamber not being movable.
