摘要： Single sheet feeding from a stack is provided by placing the stack onto flat bars defining a stack bottom and being part of a pivotable frame. That frame includes holddown fingers engaging the top sheet at its front edges, and, two separating rollers are provided laterally offset and at a higher level; the rollers are reversibly driven to pull the top sheet out from under the fingers, and upon reversing the rollers slide that sheet towards a platen drum being selectively drivingly coupled to the separating rollers.

摘要： A feeder for a printer serves for guiding and/or advancing the record carrier. Tractors (1a and 1b) placed in a pair are provided. The tractors (1a and 1b) have hinged parts which can be adjusted in different hinged positions by pivoting bearings (11). To provide hinged part on printers, particularly dot matrix printers, with simple pivoting bearings that can be produced economically and to eliminate a special fastener for the pivoted positions, a spring steel wire piece (18) cut to length serves as a pivot pin (17) and for fixing of the closed and open end positions of the hinged part (10). The spring steel wire piece (18) is put under tension by bending.

摘要： It is proposed that a pneumatic suspension leveling system for vehicles with a compressor which can be turned on and off by a control device in function of demand, which compressor only needs to operate intermittently, with predetermined on-time duration, during normal operation, be improved with respect to its functional capacity. This problem is solved in accordance with the invention in that the control device of the pneumatic suspension leveling system varies the on-time duration of the compressor in function of the heat transfer conditions which prevail between the compressor and the air enveloping the latter.

摘要： A printer with a print-head distance-setting device for adjusting the distance (1) between print head (2) and print-material counter support (3) for recording-material carriers (4) of unequal thickness, resting on the print-material counter support (3), including a mechanical sensing member (5) for controlling a print head (2), adjustable in a direction perpendicular relative to the longitudinal direction of the slider carriage motion, where the print head (2) is disposed on a longitudinally movable print-head slider carriage (7), which print-head slider carriage (7) in turn is guided with a pair of parallel guide axles (9), of which one guide axle (9) is supported by way of a pair of eccentric-disposed pins (10) and of which the second guide axle (9) is cross-movably supported in the printer side walls (32). In order to achieve a simpler and more easily constructed print-head distance-setting device, which can in addition be controlled more accurately, an electrical analog signal, generatable by the setting motions of the sensing member (5), serves in a converted configuration of an electronic digital signal in an electronic circuit (11) for the control of a step motor (12), supported at a printer frame, where the step motor (12) forms a servo drive (13) for the pair of eccentric-disposed pins (10) of the guide axle (9).

摘要： A linear or annular optical grating cooperates with a detector unit having two detectors on the front face of a carrier member of rotational symmetry and being either directly rotatable through a rear-face screwdriver slot, or via a cam-operated lever, the cam being rotatable by screwdriver action. The two detectors are aligned along a diameter line of the carrier member and will produce two phase-shifted pulse trains upon relative movement between the detection unit and the grating. The preferred field of application is matrix printers, the grating defining print position.
