Abstract: The invention relates to a signal inducing device (1, 9, 11, 12, 18, 19, 20), comprising a first material (2, 3, 13, 14) and a second material (4, 16). The first material (2, 3, 13, 14) and the second material (4, 16) show a different magnetic behaviour. The first material (2, 3, 13, 14) and the second material (4, 16) are arranged in a way that the resulting magnetic behaviour of the signal inducing device (1, 9, 11, 12, 18, 19, 20) varies over a magnetic interaction surface (5, 10) of the signal inducing device (1, 9, 11, 12, 18, 19, 20). The signal inducing device (1, 9, 11, 12, 18, 19, 20) is designed in a way that the magnetic interaction surface (5, 10) shows an essentially smooth surface, in particular with respect to the standard moving direction of the magnetic interaction surface (5, 10).

Abstract: The invention relates to a hydrostatic bent axis power unit having a synchronizing joint for the angularly adjustable drive-connection of a cylinder block, which has pistons, to a driveshaft. The synchronizing joint has a shank which is rotatable about its longitudinal axis and thereby defines the joint axis, on the ends of which shank at the drive input and drive output side are provided in each case laterally projecting roller carriers which define a roller axis, which is aligned approximately at right angles to the joint axis, for rollers which are provided on the roller carriers, and against the two ends of which shank bears in each case one connecting pin which is aligned in the direction approximately of the joint axis. In each case one securing element is provided at the two ends of the shank, which securing element both holds the connecting pin in the region of the joint axis in contact against the shank and also prevents the rollers from sliding off the roller carriers.
