    摘要: A pressure controlled cutter bit or drill bit retainer in the form of a revolving drill head with hydraulic precision adjustment of the drill bit arranged at a central extension, which is displaceable from its original position by small amounts around a pivot axis by a pressure motor, wherein this displacement occurs without any parts mechanically rubbing against each other and the dimensioning of the pressure motor and extension defining the transmission ratio conditions are selected in such a way that the travel of the drill bit guided along a curved path is greater than the travel of the pressure motor output produced by volume change, and wherein the overall volume of the pressure motor is selected to be slightly greater than the volume required for moving the pressure motor output.

    摘要: A printer includes a printhead, a driven platen to advance the paper, which simultaneously provides counter-pressure to the printhead, and a paper-cutting bar which includes a cutting edge on which the paper can be cut. A paper compartment holds a paper supply, through which the platen is accessible for paper insertion. A cover plate or lid covers the paper compartment. In order to assure safe operation, the cutting edge of the paper-cutting bar is mounted outside of the most constricted space between the platen axle and the paper-cutting bar. The end of the paper-cutting bar includes the cutting edge thus covering the platen so that the end of the cover plate penetrates beneath or overlaps the specified end of the paper-cutting bar in the closed position. When moving from the closed position to the open position, a motion device causes the cover plate to be initially moved in a linear direction to clear the cutting bar and thereafter rotate around a rotary axle which is substantially parallel to the platen axle.
