DEFINITION

Classification: 141/4

(under subclass 1) Processes which include steps relating to the presence, absence or manipulation of gas in connection with the receiver.

(1) Note. Processes of treating the contents of the receiver while in the receiver, and also processes of pretreating the receiver with gaseous fluid are included.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5+, for processes of filling receivers with gas and

nongaseous fluent materials.

8, for processes for evacuating receivers and subsequently filling with gas.

37+, for apparatus pertaining to the filling of receivers under conditions involving gas and contents material other than gas in a confined system, and see the search notes to subclass 37 for other apparatus in this and other classes for filling apparatus involving gaseous modification or application.
