Abstract: A plain bearing includes a base body having a substantially cylindrical bore bounded by a bore surface, and the bore surface has a longitudinal recess in a load-zone region that is open radially inward and has curved ends connected by axially extending sides. A cylindrical shaft extends through the bore and over the load zone and has an outer diameter less than an inner diameter of the bore. A fluid channel has an opening in the recess and provides fluid to the recess at a pressure that is maintained at a level to offset no more than about 40 percent of a force produced by the shaft in the direction of the load zone.

Abstract: An evaporating system for separating at least two liquids mixed with one another includes a reactor vessel for receiving the mixture from an inlet, the mixture having a mixture level in the reactor vessel, a blowing-in device for blowing a gaseous aerating agent into the mixture and absorbing the first liquid, a heating device for heating the mixture, an outlet for discharging the aerating agent and the absorbed first liquid, and an inlet for introducing a gaseous fluid above the mixture level to generate a gaseous transport stream to the outlet.

Abstract: A thrust bearing configured to support axial loads that act on a rotating body includes a thrust shaft rotatably supportable in a bearing housing, a thrust collar, and a retainer connected to the thrust shaft and configured to support a plurality of thrust pieces. The thrust pieces each have a front sliding surface in sliding contact with the thrust collar, and the retainer includes a disk having a central opening and an outer circumference and a plurality of radial incisions extending radially inwardly from the outer circumference which incisions have inner ends radially spaced from the central opening. The radial incisions define circumferentially adjacent spring sections each of the which is individually axially flexible against and away from the bearing housing to open and close a spring gap between each of the spring sections and the bearing housing.

Abstract: A protective device for a stern tube seal of a propeller-driven vessel, wherein an intermediate space is left open between a stern tube and a propeller hub, which intermediate space is covered by a tubular protective cover concentric with the propeller hub, which protective cover is fixedly anchored to the stern tube and axially overlies the propeller hub leaving an annular gap, wherein a ring concentric with the propeller hub and U-shaped in radial section is disposed inside the protective cover in the intermediate space between the stern tube and the propeller hub, the U-opening of which ring is directed radially outward, and wherein the ring is at least partially formed of a material that has a pourable consistency at 20° C.

Abstract: The present invention relates to a textile machine for producing/processing yarns, in which the empty tubes and full yarn packages are transported by a product transport system which includes a guideway for the product conveying devices, and a separate overhead rail which supports a tractor drive unit. The tractor drive unit may be coupled to either end of the product conveying devices by an elongate chain, which permits the product conveying devices to be moved onto and from said tracks which extend along an aisle along the front of the textile machine.
