DEFINITION

Classification: 264/37.14

Of gaseous process material (e.g., cooling gas, blowing gas, etc.):

(under subclass 37.1) Processes wherein the reclaimed or process material is a gas, (e.g., vapor, cloud, fog, haze, or mist, etc.) under standard conditions.

(1) Note. A gas is considered to have a very low density and viscosity, relatively great expansion and contraction with changes in pressure and temperature, to be readily diffusive, with a tendency to expand indefinitely, with molecules in free movement.
