DEFINITION

Classification: 264/37.11

Vaporizing to recycle liquid:

(under subclass 37.1) Processes wherein a liquid process material is recycled or recovered by changing to a gaseous state and back to a reusable liquid state.

(1) Note. A liquid is considered to be a state of matter which exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.

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

(3) Note. Liquid process materials found here are vaporized, condensed, and reused in a molding process.
