摘要： Method and apparatus are disclosed for removing a first immiscible liquid from a liquid mixture comprising at least two immiscible liquids. A material preferentially sorptive of the first immiscible liquid and capable of sorbing the first immiscible liquid therein and therealong is positioned as a siphon with a first or intake end contacting the first immiscible liquid and a second or discharge end placed below at least the first immiscible liquid level, and outside of the liquid mixture. The first immiscible liquid is sorbed by the material and rises therein and/or along. The first immiscible liquid is removed or "siphoned" from the mixture and discharged outside thereof when sorbing has progressed sufficiently to prime the material, which removes or "siphons" the first immiscible liquid out of the mixture. The material may also be primed independently by saturating the sorbent material. The invention is especially suitable for the removal of oil from an aqueous mixture.

摘要： Oily hydrocarbons which pollute the surface of water are removed therefrom by scattering over the polluted surface solid particles of nutrient salt containing nitrogen and phosphorous in a form that is readily assimilable by aqueous microorganisms capable of metabolizing hydrocarbons. The particles of nutrient salt are given a surface pretreatment with paraffine so that they are buoyant and only slowly soluble in water and lipophilic.

摘要： THIS PROCESS RELATES TO SEPARATING MULTIPHASE LIQUIDLIQUID MIXTURES SUCH AS EMULSIONS AND INVOLVES DISPERSING THEREIN A FERROFLUID PREFERENTIALLY SOLUBLE IN ONE PHASE OF THE MIXTURE AND THEREAFTER PASSING THE MIXTURE THROUGH A STRONG MAGNETIC FIELD GRADIENT. THE MAGNETIC FIELD SERVES TO AT LEASY CONCENTRATE, OFTEN TO SEPARATE OUT, THE PHASE CONTAINING THE MAGNETIC PARTICLES THEREIN. AS LITTLE AS 0.0001% BY VOLUME OF MAGNETIC PARTICLES IN ONE PHASE IS ADEQUATE FOR SIGNIFICANT PHASE SEPARATION BY A STRONG MAGNETIC FIELD GRADIENT.

摘要： Apparatus for extracting oil or the like from the surface of the sea. A centrally disposed ballast chamber is surrounded by a sump compartment which is sufficiently large so as to obtain deceleration of flow of the liquids which pass over an articulated weir member. The latter is connected to arm members which are provided with a substantially universal connection to the ballast chamber. A flexible skirt member forms an exterior wall portion of the sump compartment and is connected to the lips which constitutes an upper edge of the outer weir member. In this manner a pressure differential across the skirt member is communicated to an individual weir segment member in order to vary its elevation in a self-compensating manner. In a preferred form of the invention, the float members form vanes so arranged as to impart a vortex or circular swirl to the fluids passing over the outer weir. An inner weir means is used to collect oil floating on the surface within the sump which has accumulated adjacent the wall of the centrally disposed ballast chamber.
