DEFINITION

Classification: 96/155

DEGASIFYING MEANS FOR LIQUID:

(under the class definition) Apparatus which is provided with means to eliminate or drive out a gas from a liquid.

(1) Note. In order to distinguish the apparatus of this subclass from that used for distillation as found in Class 202, which is used to separate a liquid constituent by volatilization from a plurality of liquids, only degasifying means providing for the removal of a normally gaseous constituent at STP (i.e., standard temperature of 0 deg.C and pressure of 760 mm Hg) from a liquid will be classified in this subclass. If, however, a constituent is at a temperature above its boiling temperature for a particular pressure, then the constituent is presumed to be a gas, and a patent to apparatus for removing the constituent will be placed here. See search class notes below.

(2) Note. The apparatus of this subclass may be used to degasify a liquid which was formed as a result of a prior system treatment (e.g., regeneration of a liquid that was used to remove a gas from a plurality of gases, etc.).
