DEFINITION

Classification: 141/47

(under subclass 37) Apparatus in which plural gas flows to or from the receiver occur other than or in addition to the displacement of gas from the receiver by the nongas material, or the control of a single gas flow to or from the receiver is operated during the cycle of filling the receiver in some way other than by merely turning it on and/or off. The special operation may involve repeating any gas control operation, changing pressure or quantity, shifting the gas supply to another use, or changing sources during the filling operation.

(1) Note. Manual operation of the gas control apparatus is not included even though the sole disclosure is that repeated operations for the same receiver occur.

(2) Note. Apparatus which during the cycle changes the gas condition to change the equilibrium requirements of the system is included.
