criteria of the device application_number US 55445483 A description each figure is a graph which plots against time t the path of the rotation rate n of the drum of a centrifuging device and the imbalance u occurring on the drum on acceleration imbalance can be understood here to be the geometric displacement of the centre of gravity in the drum or its product with the rotating mass or the oscillating force occurring on rotation as a result of the displacement of the centre of gravity this may be measured for example with a suitable power sensor on the bearing of the centrifuging device whereby the variation signal is indicative of the imbalance and with a horizontal drum axis the equisignal for the mass i e for the residual moisture of the washing expediently particularly for large and heavy centrifuging devices a hydrostatic bearing with movable support pistons and dynamic characteristic property is used as is described for example in u s pat no 4 113 325 here the imbalance force can be directly determined through a measurement of the deflection of the support piston it may also be expedient to combine the measured imbalance with the rotational rate which is also measured by means of a suitable circuit arrangement or with a microprocessor and to convert to the theoretical imbalance which is to be expected in operation with the operation rotation rate provided and to use the projected imbalance as standard amount fig1 shows an acceleration method for a centrifuging device specifically a washing centrifuging device with horizontal axis in which rotation speed n first of all.
