.~ Constant weight, volume or pressure control by output
DEFINITION
Classification: 222/55
(under subclass 52) Dispensers having means which responds to the volume, weight, or pressure of material already discharged without restraint on such material and correspondingly affects the discharge means employed, usually to secure uniformity of discharge regardless of varying conditions of the material as to specific gravity, etc., thus giving a constant feed from the source regardless of rate of use.
SEE OR SEARCH THIS CLASS, SUBCLASS:
56, for dispensers having a source delivering to a receiver which is also discharging, there being means responsive to the quantity of material in the receiver to control discharge from the source thus containing a variable feed from the source due to the rate of use.
57, for dispensers controlled by the volume, weight, pressure or rate of flow of a second material.
353, 437, 457, and 479, for barometric or angle of repose devices in various combinations.
