Abstract: Instead of a conventional slide arrangement Z/X/Y and a B-axis that is pivotable thereon, a more compact and less complex configuration is achieved in that a tool support that is pivotable about the B-axis is directly placed onto the X-slide and only a single rotationally drivable tool spindle is additionally movable in Y-direction in this pivotable tool support, whereas all other tool receivers for stationary tools are fixated at the support.

Abstract: According to one aspect of the invention, an apparatus and process are provided for transporting sheet-shaped print material. A first transport element and a first contact element are actuated to transport a sheet-shaped print material with alignment against an alignment stop. A second transport element and a second contact element are actuated to transport sheet-shaped print material past the alignment stop without alignment against the alignment stop.

Abstract: The invention relates to a power supply unit with an inverter which cooperates with a resonant circuit (L, C) and can be controlled so as to adjust the output power by means of a control unit (6).

Abstract: The invention relates to a series resonant converter (1) comprising a control circuit (8) for controlling the output voltage of the converter. To improve the behavior of the converter, it is proposed that the control circuit (8) is provided for processing a first actual value (Uout), which depends on the respective converter output voltage (uout(t)) and for processing a second actual value (UC), which depends on the respective current (ires(t)) flowing through the series resonant circuit elements (C, L, R) of the converter (1), and that the control circuit (8) is provided for delivering a correcting variable (u) determining the scanning ratio of a pulse-width modulated voltage (upwm(t)) delivered to the series resonant circuit of the converter.
