20160108957 | MAGNETIC BEARING HAVING PERMANENT MAGNET ASSEMBLIES WITH REPULSIVE BEARING SURFACES - The magnetic bearings make use of magnet assemblies with a high magnetic field gradient. The magnet assemblies use two permanent magnets with opposite polarisation in a Kittel open domain structure. The basic factor of magnetic separation is the magnetic force, which acts on a particle of the substance and which is proportional to the magnetic susceptibility of the substance, the value of the magnetic induction B and the value of the gradient ∇B of the applied magnetic field. Therefore, increasing the sensitivity and selectivity of magnetic separation will require use of the highest possible values of magnetic induction B and magnetic field gradient ∇B, or their united factor—the product B∇B. The magnetic assembly have repulsive magnetic systems each having two juxtaposed permanent magnets | 04-21-2016 |

20150266030 | METHOD FOR FORMING A HIGH-GRADIENT MAGNETIC FIELD AND A SUBSTANCE SEPARATION DEVICE BASED THEREON - A method of creating a zone of high-gradient magnetic field in a Kittel open domain structure is disclosed. The method is based on a magnetic system of an open domain structure type and is embodied in the form of two substantially rectangular constant magnets which are mated by the side faces thereof, whose magnetic field polarities are oppositely directed and the magnetic anisotropy is greater than the magnetic induction of the materials thereof. The magnets are mounted on a common base comprising a plate which is made of a non-retentive material and mates with the lower faces of the magnets, thin plates which are made of a non-retentive material, are placed on the top faces of the magnets and forms a gap arranged above the top edges of the magnets mated faces. A nonmagnetic substrate for separated material is located above the gap. | 09-24-2015 |
