DEFINITION

Classification: 141/54

(under subclass 37) Apparatus in which the filling head comprises plural diverse gas passages.

(1) Note. The diverse passages are provided for incoming or outgoing gases or for gases supplied at different times or for different purposes.

(2) Note. The gas passages may be either branched or noncommunicating.

SEE OR SEARCH THIS CLASS, SUBCLASS:

285+, for filling means or heads having multiple passages, one of which usually comprises a vent which provides for the passage of gaseous material to or from a receiver being filled under atmospheric pressure conditions or conditions indistinguishable from such. Sequential operation of the valves for gas and nongas materials is not considered significant except in lateral travel filling assemblies.
