Abstract: A piston, which has a piston rod, is guided with freedom of axial movement in a cylindrical pressure tube. At one end of the pressure tube, the piston rod passes through an opening in an end wall, which closes off the end of the pressure tube. The pressure tube is surrounded by a heat-shrink sleeve, which, at the exit end of the piston rod, extends more-or-less radially inward and has a pass-through opening through which the piston rod extends. The ring-shaped end surface at the piston rod exit end of the pressure tube is enclosed by the heat-shrink sleeve.

Abstract: A clutch sleeve assembly for an automotive clutch system includes a polymer sleeve having a snap ring groove and a metal bushing disposed within the polymer sleeve having a flange that acts as a reinforcement for the snap ring groove. There are two configurations of the snap ring groove on the polymer sleeve. In the first configuration, the polymer sleeve has a notch around an outer circumference along its edge adjacent the bushing flange. In this configuration, the bushing flange extends beyond the polymer sleeve edge to form a snap ring groove in conjunction with the notch. In the second configuration, the polymer sleeve has a snap ring groove around its outer circumference spaced apart from its edge that is adjacent the bushing flange.

Abstract: The invention relates to a method and to an arrangement for the synchronization of the image recording of monochrome recordings and color recordings with photosensitive line sensors. A line-scanning pattern is generated by a programmable counter arrangement, wherein the timer measures the phase position of the line-scanning pattern, generated by the counter arrangement, with the aid of the computer and the programmable counter arrangement at the point in time of the impinging of a pulse of the incremental transmitter, wherein the timer compares these with a coordinated calculated or tabulated reference value, and wherein the timer employs the thus obtained phase difference in order to influence a counter, preconnected to the line counter CT2, in its count volume (FIGS. 1 and 2).
