Abstract: A separating device which utilizes a centrifuge which is driven by a motor for processing liquids enriched with solids by forcing the solids out of the liquid against a peripheral centrifuge wall as a consequence of centrifugal force characterized that a collecting vessel is the centrifuged container. The collecting vessel or centrifuge chamber has a plurality of axially spaced partitions with concentrically arranged openings to form axially spaced chambers which will collect the solids separated from the liquid as the liquid is discharged from the device. In one embodiment, the collecting vessel and centrifuge chamber are a single molded member. In another embodiment, there are two parts, with one being a container-like part receiving an insert having the parititons.

Abstract: This invention relates to coating compositions based on aqueous polyurethane dispersions and to the use of these coating compositions for the production of top coats or finishes on PVC. The coating compositions according to the invention contain a mixture of two aqueous polyurethane dispersions which have particular chemico-physical properties.

Abstract: An emergency run guide assembly for the axles of a bogie frame for rail cars which have axle boxes and wich have spring leaf guide rods for the axle guidance of bogies which are secured at their one ends on the bogie frame and at their other ends on the axle boxes, and which guide rods are subjected to breakage, comprises a secondary guide system including bushings secured vertically on the bogie frame and having a central bushing wall. An axle box housing on the axle of the bogies is provided with a bore for the vertical mounting of a bolt thereon. A cylindrical sleeve member has an open bottom end and an opposite top closed end with a bore therethrough and it is mounted on the bolt with its open end downwardly. The walls of the sleeve member are spaced radially outwardly of the bolt and radially inwardly of the cylindrical bushing wall and the sleeve member is secured to the bolt by means of a locking screw which extends through the opening of the sleeve member and is threaded into the bolt.
