  • Patent number: 4879027
    Abstract: A binary fluid system, and components thereof for producing an impregnated metered fluid stream. Broadly, a container is included in the system and contains upper and lower, first and second fluid phases, i.e., liquids, gases or a combination of the same, which fluid phases meet at a common, unobstructed horizontal boundary or junction, extending the cross sectional width of the container. The fluid phases are of differing density, molecular weight, or specific gravity with the lighter phase being on top. Plural means are coupled to the container for replenishing both of the phases and also for drawing off, at a metered flow rate, the first or upper phase as impregnated by said second phase through diffusion processes across the common phase boundary, the withdrawal being from the container at the volumetric position of the first phase and proximate and above such phase boundary. The invention has special application to recirculating systems as may accommodate swimming pools, by way of example.
