    • A pressure control arrangement for controlling pressure between a printing roller and an offset roller by measuring a force exerted in a bearing of the printing roller when the latter rotates with an angle .psi.. The arrangement includes a piezoelectric pickup positioned on the internal surface of the bearing of the printing roller, a measured pressure value processor for receiving a signal from the piezoelectric pickup, an indicator generating a signal corresponding to a desired pressure value and means to compare the first abovementioned signal with the second mentioned signal. The arrangement also includes a positioner circuit which receives the compared signal and applies the same to a drive member which adjusts the position of the bearing of the offset roller thereby adjusting printing pressure between two contacting rollers for printing on sheets of paper.
    • 一种用于通过测量当印刷辊以角度psi旋转时施加在印刷辊的轴承中的力来控制印刷辊和胶印辊之间的压力的压力控制装置。 该装置包括位于印刷辊的轴承的内表面上的压电拾取器,用于接收来自压电拾取器的信号的测量压力值处理器,产生对应于期望压力值的信号的指示器,以及将第一 上述信号与第二个提到的信号。 该装置还包括定位器电路,其接收比较的信号并将其施加到调节偏移辊的轴承的位置的驱动构件,从而调节用于在纸张上打印的两个接触辊之间的印刷压力。

    • A shaft-hub connection between one shaft segment comprises one central toothed segment, the same as adjacent centering segments and one stepped hole in a hub, in which the shaft and the hub are jointed in axial direction and by the toothed shaft segment a positive fit is formed with the hub, in which the front centering segment, lying in joint direction, has a diameter d1 and the toothed shaft segment, the same as the rear centering segment lying in joint direction, has a diameter d2 larger than d1. It is proposed that the hole has only two adjacent segments I, II of different diameters D1 and D2, that the diameter d1 in the centering segment with the diameter D1, the same as the diameter d1 in the centering segment with the diameter D2, form a respective joint fit and the diameter d2 in the area with the diameter D1 forms the positive fit.

    • A direct drive for a drill bit in a drill string has a fluid-operated motor within a drive section connected by a gear section to a bearing section whose inner tube is coupled to the drill bit to accommodate axial displacement of the drill bit within the outer tube, spring elements are braced against a radial bearing for the inner tube which has at least one axially defined race. The coupling between the inner tube and the gearing also accommodates such axial displacement and a reservoir for oil is located between the drive and gear sections so that oil can be fed to the gearing, the bearings and to an axial bearing in an annular oil-filled space between the drive and gear sections.
