| 321 | GRAVIMETRIC SEPARATION SYSTEM AND METHOD | PCT/US2007004526 | 2007-02-21 | WO2007098211A2 | 2007-08-30 | SMYTHE R J |
| A method for separating components of a material includes assaying the material to determine the components and the specific gravity of at least one component. The material is ground into a heterogeneous gangue of predetermined particle size. Optionally, the particle size is determined according to Stokes' law. The gangue is delivered to a fluidizing bed having a gas permeable floor and a gas source delivering gas through the gas permeable floor at a predetermined gas flow rate, optionally corresponding to the terminal velocity of a component to be separated from the gangue. The gangue separates according to specific gravity and particles are extracted at a predetermined distance from the fluidizing bed. | ||||||

| Systems and methods for collecting data pertaining to glass, plastic and/or paper composition within an input stream that includes recyclable material. The data collected can pertain, for example, to the weight and/or volume of the glass, plastic and/or paper within the input stream. The data can be certified for use a third party. | ||||||
| 323 | SEPARATION OF FINE GRANULAR MATERIALS | PCT/GB0204463 | 2002-10-03 | WO03028877B1 | 2003-06-19 | KING PETER JOHN; SWIFT MICHAEL ROBERT; BURTALLY NASREEN |
| This application concerns the separation of fine granular mixtures that may occur when the grains are suitably vibrated within fluid. In particular, the present invention provides a method of separating a particulate mixture comprising different particle types, comprising subjecting a supported particle bed comprising a fluid and said particulate mixture to a vibration thereby to effect separation of the particulate mixture into strata each of which is preferentially rich in substantially one particle type. Apparatus for effecting the above method also provided. | ||||||
| 324 | DUAL-CELL MECHANICAL FLOTATION SYSTEM | PCT/US0118336 | 2001-06-07 | WO0196026A3 | 2002-06-13 | STACY MELVIN; TOLMIE KENNETH C; CHEN JAMES C T |
| It has been discovered that a mechanical flotation system having only two cells can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation (10) system has, in sequential order, an inlet chamber (16) and two gasification chambers or cells (18, 20), each with at least one gas ingestion and mixing mechanism (32), and a discharge chamber (24). A common primary skim collection channel (40) atop the partition (44) dividing the gasification chambers (18, 20) efficiently channels away the bulk of the floating collected matter. At least one baffle (60) depending from the top of the vessel (12) near the primary skim collection channel (40) helps dampen the action of the fluid containing the suspended matter when the vessel (12) is affected by wave motion against the floating oil production platform. | ||||||
