Abstract: Constant-velocity fixed joints may comprise an outer joint part with outer ball tracks, an inner joint part with inner ball tracks, torque transmitting balls which are guided in pairs of tracks each formed of an outer and an inner ball track, and a ball cage with circumferentially distributed cage windows in which the balls are received. Here, the balls are held in a common central plane and are guided onto the bisecting plane when the joint is deflected. Constant-velocity rotary joints of this type are known as Rzeppa fixed joints (RF) or as undercut-free fixed joints (UF).

Abstract: An assembly having a shaft (11) with external splining (23) of a limited length at a shaft end (27), and a hub (41) with a corresponding internal splining (43) that extends essentially the length of the hub. A first axial securing mechanism functions between the shaft and hub, prevents the hub from sliding further onto the shaft, and includes a stop surface (44, 46) on the hub and a counterpart surface (28, 59) on the shaft. A second axial securing mechanism functions between the shaft and hub, prevents the hub from being pulled off from the shaft, and includes a securing ring (51) that is situated at the end of the shaft and the end of the hub oriented toward the shaft end and that engages in radial recesses (48, 54) in the shaft and hub. The recesses form contact surfaces for the securing ring on the shaft and hub.

Abstract: A filter plate having defects that may cause image artefacts is moved during an exposure. The movement distributes the defects of the plate in the image to a point where they can no longer be seen in the image. Preferably, the shifting of the plate is done in the plane of the plate, in a direction perpendicular to the axes of the rollers used for in the manufacture of the plate.
