20140190882 | Fluid Cleaning Medium and a Fluid Cleaning Device - A fluid cleaning device is disclosed for cleaning pond water and the like. The device comprises a flow path for conveying a fluid flow between a device inlet and a device outlet, the path comprising a cleaning chamber having an inlet for receiving fluid into the chamber and an outlet for passing fluid from the chamber. The chamber comprises a cleaning medium which is arranged to clean the fluid as it passes along the path between the chamber inlet and the chamber outlet. The medium comprises a plurality of discrete cleaning units which separately comprise a body having a surface comprising a plurality of protuberances disposed thereon, which are arranged to maintain a separation of the body surfaces of adjacent units of the medium to enable fluid to pass between the units. The device further comprises dispersing means disposed within the duct upstream of the cleaning chamber for dispersing the fluid flow across the cleaning medium to encourage the interaction of the water with the cleaning medium. | 07-10-2014 |

20100279887 | NONLINEAR MAGNETOPHORETIC SEPARATION OF BIOLOGICAL SUBSTANCES - A method of separating a target biological analyte from a mixture of substances in a fluid sample employs nonlinear magnetophoresis. Magnetic particles having the capacity to bind to the target analyte are contacted with the fluid sample so that the analyte is immobilized on the surface of at least some of the particles. The magnetic particles are provided adjacent an array of micromagnets patterned on a substrate so that the particles are attracted the micromagnets. The magnetic particles are then subjected to a traveling magnetic field operating at or above a frequency effective to sweep those particles not bound to analyte to an adjacent micromagnet. Those magnetic particles bound to analyte have a larger size or smaller magnetic moment that prevents them from being moved to adjacent micromagnets, thereby affording separation of the analyte. | 11-04-2010 |
