Abstract: A ventilation system for a cabinet, such as a cabinet containing heat-producing components of a data processing system, those components being arranged stacked in the cabinet in tower fashion, has four identical fan units for drawing air over the components and discharging the air from the cabinet. The fan units are disposed at mid-height in the cabinet, and are divided into two pairs. The fan units in each pair have their respective air intake directions facing toward each other. The fan units of one pair are disposed directly one above the other, and the fan units of the other pair are disposed a distance apart, forming a horizontal air duct therebetween. Partitions are disposed in the cabinet for causing the fan units in the first pair to discharge air into the duct formed between the fan units of the other pair, the duct conducting the air to an exterior of the cabinet. The partitions cause the fan units of the other pair to discharge air in a direction out of the cabinet.

Abstract: A printer for selectively printing on one or both sides of a web-shaped recording medium includes a paper turn-over apparatus in the paper conveying channel. The turn-over apparatus is a removable unit and can be changed from a turn-over operation for two sided printing to a parallel conveyance for one sided printing of two recording mediums. A conveyor that moves the recording medium through the printer has an adjustable width to adapt to different recording medium widths. The conveyor includes a return which returns the recording medium to the turn-over apparatus after being printed on one side. The return includes a traction roller pair and a lever to swivel one of the rollers in and out. A connecting channel leads from the traction rollers and includes guide baffles. Conveyor rollers are arranged along the connecting channel at less than the spacing of the folds in the folded recording medium.

Abstract: An electrographic printer device is designed for printing tape-shaped recording media (10) with different tape widths in different operating modes such as single-color and multi-color simplex printing, single-color and multi-color duplex printing and for simultaneous printing of two recording medium webs in parallel operation. It comprises a module-like device structure with a printer module having a means for generating toner images arranged therein. A single fixing station (18) is arranged above this means. Via a deflection means (28), the recording medium (10) is supplied in single-color or multi-color duplex mode to a return channel (38) that contains a turn-over station (30).

Abstract: In order to control an energy-saving state of a cathode screen (M) by a control device (PC) connected thereto via a standard interface (SS) for its operation without the individual devices' being restricted to use in an arrangement with instruments tuned to one another relatively to the control of the energy-saving state, there are means for transmission, independent of the function of the standard interface (SS), of information (SB) controlling the energy-saving state of the cathode screen (M) in coded form between the control device and the cathode screen (PC and M).

Abstract: A threaded rod is fitted to a plug-in assembly which can be inserted into a mounting rack, which threaded rod is aligned in the insertion direction and becomes operatively connected to a motor-driven threaded nut during insertion. The first thread pitches are designed such that the rod and nut latch on one another.

Abstract: The invention relates to a dispensing unit for banknotes (42), comprising a banknote container (12) and a receiving module (14) which is in the form of the frame into which the banknote container (12) can be pushed. The unit includes an extracting and separating device for extracting banknotes (42) through an opening of the banknote container. The opening can be closed by a flap (26) and a closure plate (30). A retracting element (34) presses the banknotes against the extracting device by a force (P), before the flap is closed. The banknotes which are located in the banknote container are thereby forced away from the opening, back into the container interior. The retracting device is displaced in the direction of the extracting device (34) until the banknotes (42) come into the extracting position.
