Abstract: A device for the magnetic separation of a fluid including first particles to be separated of magnetic or magnetizable material and second particles of non-magnetic or non-magnetizable material may include at least two magnet arrangements for generating a magnetic induction B, which are arranged in line with one another with regard to a center axis M, wherein neighboring magnet arrangements have an opposing pole arrangement and are arranged at a distance d from each other for the generation of a cusp field. The device may also include at least one conveying line for transporting the fluid, the line having a longitudinal axis extending, at least in the region of the magnet arrangements, on a plane aligned perpendicularly in relation to the center axis M between neighboring magnet arrangements. The conveying line(s) may have at least one branch downstream of the center axis M, along the transporting direction of the fluid.

Abstract: A device separates ferromagnetic particles from a suspension. The device has a tubular reactor through which the suspension can flow and which has a first region and a second region in the passage direction. The device also has a device for generating a magnetic field along an inside reactor wall. In the second region the tubular reactor has a tailings discharge pipe and a concentrate separation channel surrounding said pipe. The cross-sectional area of the tubular reactor in the second region is larger than that in the first region.

Abstract: In devices for producing strong current high power impulses, the electronic components, which include passive components including capacitors and/or switch elements, including semi-conductor switches, diodes or similar elements, need to be protected against overcurrents in the event of an error function. Generally, serial resistance and serial inductance are used. The serial resistance and the serial inductance are combined together in such a manner that a coil having necessary resistance and inductance values is produced.

Abstract: In devices for producing strong current high power impulses, the electronic components, for example, passive components such as capacitors and/or switch elements, such as semi-conductor switches, diodes or similar elements, need to be protected against overcurrents in the event of an error function. Generally, serial resistance and serial inductance are used. The serial resistance and the serial inductance are preferably combined together in such a manner that a coil comprising necessary resistance and inductance values is produced.

Abstract: A switching contact is disclosed for vacuum interrupters, having a radial or axial magnetic field. In at least one embodiment, the switching contact includes a switching contact carrier and a contact plate. The switching contact carrier contains a coil for generating a magnetic field, said coil being formed by slitting the wall of a pot-like contact carrier. The outer diameter of the slitted wall of the pot-like carrier is smaller than the diameter of the contact plate located thereon. The switching contact is also provided with an annular supporting body which is inserted between the contact plate and the base of the contact carrier and surrounds the contact carrier at least in the slitted region. A vacuum gap is provided between the outer supporting body and the slitted wall.

Abstract: A high-voltage pulse generator includes a storage capacitor which is connected to a voltage source via leads. One of the leads is connected to a reference potential via a node point. A switching device is connected in parallel with the storage capacitor on the voltage source side. An output inductance is connected to the one lead via a further node point arranged between the storage capacitor and the first node point. A diode lies between the node points.

Abstract: At least main electrodes for a low pressure gas discharge arranged at a distance from each other are present in such switches, the main electrodes forming a cathode and an anode of a discharge path in an interrupter chamber for the gas discharge which is fired by increasing electron density in a cathode cavity. For this purpose, at least the cathodes have at least one opening, preferably the cathode and anode, having opposite aligned openings for triggering the discharge. In such an arrangement, an arrangement for the generation of a magnetic field superimposed on the discharge may be present. At least one slot is present in at least one of the main planar electrodes for generating a radial magnetic field. A single slot maybe provided which runs in the form of a spiral from the area of the electrode center to the area of the electrode edge.

Abstract: In automobiles, for example, the exhaust fumes must pass through a plasma reactor operating by the principle of dielectrically inhibited ("silent") discharge, consisting of an arrangement of flat plates with alternating metallic and dielectric layers, whereby a plurality of adjacent discharge paths in parallel in the flow direction are formed. According to the invention, the discharge paths border on a single metallic electrode surface or layer (62, 72) and the electric power is supplied (58, 59) from two different sides with the metallic layers (62, 72) having alternating polarities.
