The invention relates to a deviation ring for paste comprising an annular rebound wall () for a self-distributing centrifuge (). The invention also relates to a corresponding self-distributing centrifuge (). In the deviation ring, the angle of incidence ? of the tangents of the rebound wall () of the deviation ring (), opposite the distribution slit () of the centrifuge (), in relation to the horizontal, is between 3 and 60&#xb0; over the entire opening width of the distribution slit ().

Method for separating blood plasma particles from a blood plasma suspension in a self-discharging centrifuge having two or more discharge slits and axially stacked baffle plates, in which the blood plasma particles are separated from the liquid phase by centrifuging and removal of the liquid phase, suctioning off liquid remaining in the drum after separation of the blood plasma particles and discharging the sediment of solid blood plasma particles from the drum by centrifugal force into a collecting container underneath the drum, the drum and the blood plasma sediment being cooled during one or more of the process steps.

The invention provides an improved process for the preparation of double metal cyanide (DMC) catalysts for the preparation of polyether polyols by polyaddition of alkylene oxides on to starter compounds containing active hydrogen atoms, in which aqueous solutions of a metal salt and a metal cyanide salt are first reacted in the presence of an organic complexing ligand and optionally one or more further complex-forming components to form a DMC catalyst dispersion, this dispersion is then filtered, the filter cake is subsequently washed with one or more aqueous or non-aqueous solutions of the organic complexing ligand and optionally one or more further complex-forming components by a filter cake washing and the washed filter cake is finally dried, after an optional pressing out or mechanical removal of moisture.
