    摘要： The process for producing granular sodium percarbonate by fluidized bed buildup granulation comprises the spraying of an aqueous solution of hydrogen peroxide and of an aqueous solution of sodium carbonate with at least one multisubstance nozzle with external mixing into a fluidized bed comprising sodium percarbonate particles and simultaneously evaporating water, and is characterized in that the solution of sodium carbonate additionally comprises sodium carbonate and/or sodium percarbonate in suspended form and is passed through a dispersing apparatus for dispersion of solids before being fed to the multisubstance nozzle.The process allows the blockage of the multisubstance nozzle to be avoided and sodium percarbonate dust to be recycled from the offgas stream of the fluidized bed into the granulation.

      摘要： In a process and an apparatus for determining the coercive field strength and the maximum pitch of the hysteresis cure in set-up techniques a test body is magnetized in a magnetic field of an exciter coil fed with an alternating current, as the hysteresis curve of the test body is traversed a number of times with the frequency of the alternating current and the tangential field strength on the test body surface generated by the exciter coil is detected continuously with the aid of a magnetic field strength sensor during the traversing of the hysteresis curve. From a harmonic analysis of the time course of the tangential field strength within one period there is calculated a distortion factor for the determination of the maximum pitch of the hysteresis curve. The coercive field strength is ascertained by the means that the point of time of the first zero passage of the harmonic signal after the zero passage of the tangential field strength signal is sought and the amplitude of the tangential field strength signal present at this point of time is regarded as measure for the coercive field strength.
