DEFINITION

Classification: 96/243

WITH GAS AND LIQUID CONTACT APPARATUS:

(under the class definition) Apparatus having means to cause separation of a gaseous fluid mixture combined with means to bring the gaseous fluid mixture or a separated gaseous constituent into (1) intimate confluent, countercurrent, or generally mingling relationship with a contact liquid or (2) into contact with the surface of a reservoir or supply tank of a contact liquid.

(1) Note. The means for contacting the gaseous fluid mixture with a liquid generally results in separation of a gas, solid particles, or liquid particles from the gaseous fluid mixture (e.g., sorption, scrubbing, etc.). However, the means for contacting the gaseous fluid mixture with a liquid does not have to cause separation of the gaseous fluid mixture, but may be used for other reasons (e.g., to humidify a gas, etc.). In order for a patent to be placed in this subclass, there must be means to cause separation of the gaseous fluid mixture by some apparatus of this class combined with the means to cause gas and liquid contact (e.g., a liquid bath combined with a filter or deflector for mist elimination, a filter combined with a liquid sprayer for humidification, etc.). Gas and liquid contact apparatus, per se, for gas separation or for other reasons is classified

elsewhere (see the SEARCH CLASS note below).

(2) Note. In order to qualify under portion (1) of this definition, the gas and liquid contact apparatus must be of the type described as classified, per se, elsewhere (see the SEARCH CLASS note below).
