    摘要: One aspect of the invention provides a device for sorting non-magnetic particles. The device includes: (a) a fluid holding chamber comprising an inner and outer surface; (b) a fluid in contact with the inner surface of the fluid holding chamber, said fluid containing a dispersion of magnetic particles and at least two sets of non-magnetic particles; and (c) at least two sources of magnetic fields positioned in close proximity to, or inside of, the fluid holding chamber. The at least two sources of magnetic fields produce a changeable pattern of magnetic field minima and maxima regions thereby causing said non-magnetic particles in the fluid to be transported towards the magnetic field minima regions by magnetic force. At least one of said sources of magnetic fields comprises an array of magnetizable features on a micrometer or nanometer length scale.

    摘要: Apparatus for, and method of, containing, transferring and electromagnetically stirring an electrically conductive fluid is provided. A vessel is formed from spaced-apart annular structural elements, or hoops, that are bound together by a high-temperature electrical insulating material, which also forms the interior surface of the vessel. Reinforcing members are embedded in the high-temperature electrical insulating material and passed through the hoops. The vessel is disposed within an electrical stator having multiple electrical poles. Each pole is wound with a separate coil. Current can be supplied to each coil winding, with a suitable phase shift between currents to all coil windings, to achieve an electromagnetically induced stirring and heating of the electrically conductive fluid. The vessel may be removably disposed in the electrical stator so that the vessel can be transported to and from the electrical stator for induced stirring.
