    摘要: The invention relates to a magnetofluid-supported electromagnetic drive for a blood pump for supporting or partially to totally replacing the heart whereby the blood pump in its weight as well as its energy density nearly corresponds to the natural heart and is especially suitable for an implantation whereby a reduction of the total system in comparison with known systems is to be made possible and the efficiency is improved at the same time. This task is solved by the blood pump having a magnetofluid-supported electromagnetic drive consisting of one or several electromagnets and force-transforming facilities and with the space of at least one electromagnetic circuit being completely or partially filled with magnetofluid, whereby the poles show permanent-magnetic properties. Thereby, a magnetofluid with a saturation magnetization of 150 to 450 mT has been used with an initial permeability of 5 to 25.

    摘要: The invention provides a device for the axial delivery of fluidal mediums, which outer diameter is not or only insignificantly larger than the diameter of the fluid carrying pipe, which reduces to a large extent a shearing and vortexing of the fluid. A device for the axial delivery of fluidal mediums, having a tubular hollow body arrangement, in which delivery area, an impeller (9) with a blading, which can be rotated, is arranged and also has a fluid directional means. A motor (2), at least one impeller (9) which can be rotated, and at least one motor mounting (14) are arranged in a tubular hollow body (1) of the hollow body arrangement. The impeller (9) is connected axially force-fittingly and/or form-fittingly to the motor (2).

    摘要: The invention describes a process and an appliance for separating non-magnetic materials and objects with the use of magnetic fluids. With this invention a restoration of the magnetic fluid adhering to the separated material is made possible, by removing the magnetic liquid still adhering to the separated product both through magnets as well as through water. The magnetic fluid in the separating chambers is constantly monitored as regards volume and concentration via a monitoring installation. An appropriate area of use for the invention is the separation of fragmented materials, the separation of capacitors in capacitators containing polychlorinated biphenylenes (PCB) and PCB-free capacitors. The invention described, moreover, the composition, manufacture and use of environment-friendly diluted magneto-fluids, which can be especially suitable in employment in the separation of non-magnetic materials using the sink-float process in the magnetic field gradient.
