Abstract: The disclosure concerns a radial bearing arrangement for a large diameter rotor wherein the rotor carries an annular surface in a peripheral region spaced radially from the axis which cooperates with a series of bearing devices mounted in a foundation. The bearing devices provide reactions in a limited number of main supporting directions and act collectively to restrain the rotor against movement in all radial directions. Not more than two of the bearing devices provide positive, non-yielding restraint in those main directions, whereas the other bearing devices have radially displaceable bearing shoes and furnish yielding holding forces. The arrangement may include one type of yielding bearing device which furnishes a reaction which varies with displacement and affords a centering action, and/or a second type which furnishes a constant reaction during slow displacements and an increased reaction during rapid displacement, and thus affords damping action.

Abstract: In a peeling centrifuge comprising a rotatable centrifuging drum which is surrounded by a stationary filtrate collection chamber having an outlet, and wherein the drum perforations communicate directly with that chamber, regeneration of the filter bed is effected while the drum rotates by throttling said outlet and introducing liquid to the chamber, so that liquid accumulates in the chamber and penetrates, at any instant, at least a portion of the filter bed. In one embodiment, wherein the drum axis is horizontal, only a sector of the bed in the lower region of the drum is penetrated at any time, and regeneration of the entire bed is accomplished sequentially as the drum rotates. In other embodiments, the chamber is allowed to fill with regenerating liquid to such extent that the entire bed is penetrated simultaneously. The regeneration technique may be carried out either in the terminal phase of a centrifuging operation, or after completion of centrifuging and peeling of the accumulated solids cake.

Abstract: Rolling mill for the pressure treatment of a web of material having two press gaps in each of which a different application pressure can be adjusted independently of the other gap. The two press gaps are formed between three rolls whose axes are situated parallel to one another and lie in two planes. The roll which adjoins the two other counter-rolls to form the press gaps is constructed as a pressure equalization roll with a stationary axial supporting member about which a shell is capable of rotating and in which hydrostatic supporting elements are arranged in rows extending parallel to the press gaps. The application pressure in the press gaps is produced exclusively by means of the hydrostatic supporting elements. The shell of the pressure roll shell is capable of moving in all radial directions relatively to the supporting member. The two counter-rolls are guided radially and axially.
