Abstract: A marine vessel propulsion assembly has an elastically suspended gearbox with an output drive shaft guided in an axial bearing with a rigidly suspended bearing housing. Free space is provided in the axial bearing for allowing movement of the output drive shaft in the radial direction, wherein the output drive shaft is freely movable radially within the free space. A supporting ring with sliding elements for axial guidance of the output drive shaft is arranged in the axial bearing. The supporting ring is hydraulically supported by a large number of pistons so that the supporting ring can match itself to angular displacements of the output drive shaft and can always completely and uniformly support the sliding elements on the bearing circumference.

Abstract: A compound needle for a knitting machine has a machine shank of substantially rectangular cross section, in which a substantially U-shaped longitudinal groove open at the top is formed. A closing slider adapted to fit the cross section of the groove is guided in the groove in a longitudinally slidable manner, and the groove has at least one slit leading to the outside, which extends parallel to the longitudinal axis of the groove.In order to attain satisfactory removal of fluff or lint from the longitudinal groove, on the one hand, and to assure sufficient stability and resistance to transverse bending of the needle on the other, the longitudinal groove is closed on its top, at least partially, in the vicinity of the recess by means of a rib which also forms a guide for the slider.
