摘要： The invention relates to a switching contact for vacuum interrupters, having a radial or axial magnetic field and comprising a switching contact carrier and a contact plate. Said 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. According to the invention, the outer diameter (DS) of the slit wall (23) of the pot-like carrier is smaller than the diameter (DK) of the contact plate (25) located thereon. The inventive switching contact is also provided with an annular supporting body (20) which is inserted between the contact plate (25) and the base (22a) of the contact carrier (22) and surrounds the contact carrier (22) at least in the slit region. A vacuum gap (30) is provided between the outer supporting body (20) and the slit wall (23).

摘要： Disclosed are switches comprising main electrodes separated by a certain distance for gas discharge at a low pressure and forming, inside a circuit-breaking case, the cathode and the anode with the spacing required for said gas discharge, which is triggered by increasing the electron density in a hollow cathode space. It is also necessary for the cathode to have at least one opening, and preferably that both the cathode and the anode have aligned openings facing each other. Such a system allows for elements to be provided to create a radial magnetic field above the discharge. According to the invention, the elements concerned can be at least one slot (100, 200; 200', 100'') in at least one of the planar main electrodes (1, 2). A preferred embodiment has only one slot (100, 200, 200', 200'') extending like a spiral from the central area (15, 25) to the peripheral area (16, 26) of said electrodes.

摘要： The invention relates to a method for reducing impurities which are formed by organic dyestuffs, biocatalytic substances and/or microorganisms and/or other biological material in a water system (90) during the production of flat structures from fibrous material in aqueous suspension. A method is provided for reducing the use of chemicals and/or complementary dyestuffs in order to reduce the impurities formed in the water system by a gas discharge and/or a plasma being generated by application of a voltage (U) to electrodes (50, 51) in the water (23) or in the suspension, wherein a voltage profile (60) of the voltage (U) has voltage pulses (66, 67) having a pulse duration of less than 10 μs, wherein a streamer discharge (53) is generated. A papermaking plant (1) can thus be operated in a more environmentally friendly manner.

摘要： 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.

摘要： The invention relates to a method for improving the quality of a pulp slurry (39) that is produced in a stock preparation process and is to be used for producing planar structures from fibrous materials. In order to improve the quality of the pulp slurry, e.g. obtain a bleaching effect of the fibrous materials, dilution water (24) is treated with a cold plasma or a gas discharge before being added to the pulp slurry (39).
