摘要:
In a sheet feeding apparatus for separating individual sheets (1b, 1c) of different stiffness from stacks (1d) thereof, the stack is pressed under the urgency of a spring force against separating rollers (9) and the sheet supply container (1) has an inclined front wall surface (10) on its front wall (4) upon which the stacked sheets are supported. A pair of arms (12) carrying separating elements (3) on their lower ends are carried on the supply container side wall (1a) for substantially parallel movement therealong. The arms (12) are implemented as linearly-movable switch sides (13) which are reciprocally displaceable between a lowered position in which the separating element end surfaces (15) rest against the supply container front wall surface (10) or the front region (11) thereof, and an upper or raised position in spaced apart relation to and providing a well-defined clearance (16) relative to the topmost sheet in the stack (1d).

A paper stacking apparatus is for an office machine, wherein the office machine has a forward end and a rear end and includes rollers for sequentially supplying sheets of paper upwardly along a generally vertical path. The sheets extend transversely of the office machine. The path is located between the front end and the rear end. The paper stacking apparatus includes a support frame located above the rollers for sequentially supplying said sheets. A paper guide element is mounted within the support frame in alignment with the path. A forward stacker is mounted on the support frame forwardly of the paper guide element. A rear stacker is mounted on the support frame rearwardly of the paper guide element. The paper guide element is selectively movable to a forward position and to a rear position. The paper guide element at the forward position directs the sheets to the forward stacker for forward to rear stacking of the sheets thereon. The paper guide element at the rear position directs the sheets to the rear stacker for rear to forward stacking of the sheets thereon.

A ribbon cassette having a casing with a releasable cover, includes a pulley mounted for rotation in the casing, key-means project beyond the casing of the cassette for engagement with an external drive, a pressure roller is rotatably mounted in the case, a slide movably mounts the pressure roller to obtain a first position of engagement with the pulley and a second retracted position, a projection on the slide is externally accessible through an opening in the casing for shifting the slide from the first to the second position and vice versa; an additional projection on said slide runs in another opening in the casing for guiding movement of the slide along a long wall of the cassette casing; a brake is also disposed in the cassette which holds a removable endless ink ribbon that is insertible and inserted in the casing and fills the casing essentially in its entirety, the ribbon runs through a gap between the pulley and the pressure roller on one hand and the brake on the other.

A structure is disclosed primarily but not exclusively as a supplement to an existing printer or typewriter or the like, which structure includes a clamping shaft, either for clamping endless sheet stock against the traction device for the stock, or against an added on anvil bar or both.
摘要:
In a method for monitoring the functioning of a compressor, which charges a gas-filled accumulator chamber with a working pressure, the actual pressure prevailing in the accumulator chamber is measured and compared to a setpoint pressure. In response to a deviation in the actual pressure from the setpoint pressure, an error signal is produced. The comparison of the actual pressure and the setpoint pressure is carried out during the charging operation when the accumulator chamber is charged.

It is proposed that a pneumatic suspension leveling system for vehicles with pneumatic suspension leveling elements assigned to the vehicle axles and/or vehicle wheels, with a compressor and a central pressure accumulator fed by it for the compressed air supply of the pneumatic suspension leveling elements, with an accumulator pressure sensor which detects the air pressure in the central pressure accumulator and generates a signal value correlating thereto, and with an electronic control device which processes the signal values of the central pressure accumulator and induces a pressure charging of the central pressure accumulator by the compressor, when the signal value of the accumulator pressure sensor reaches a predetermined lower threshold signal value and terminates this pressure charging when the signal value of the accumulator pressure sensor reaches a preset upper threshold signal value be improved with respect to its functional capacity. This is achieved by providing an ambient pressure sensor which detects the air pressure in the atmosphere surrounding the vehicle and generates a signal value correlating thereto, whereby the control device processes the signal values of the ambient pressure sensor and varies the upper threshold signal value in function thereof.
摘要:
A device for feeding of individual sheets to a plate (4) of an office machine, in particular of a matrix printer (1), is provided with several storage bins (5, 6). In each case a separating roller (7, 8) is coordinated to the storage bins (5, 6) and the separating roller (7, 8) is connected to a drive motor (9) via a gear train. In order to create a reliably operating storage bin selection, which can be employed for larger distances and for larger-volume storage bins, it is disclosed that the drive motor (9) can be left-hand or right-hand rotatably controlled, that the drive motor pinion (10) engages a first gear wheel (11), that an eccentrically supported cam (12) is carried by the first gear wheel (11), that the cam (12) engages into a switching rocker (13), and that at least a second gear wheel (15) is rotatably supported at the switching rocker (13) supported around a horizontal axle (14), where the second gear wheel ( 15) is tilted, depending on the rotary direction of the drive motor (9), into engagement with the respective gear wheel (16, 17) of one of the separating rollers (7, 8).
摘要:
A printed sheet delivery device (3) for a printing station (1) includes a collection tray (7) reciprocatable by a transverse-displacement drive (6) for receiving and sorting sheets (2) in stacked, printed-side-down relation in transversely staggered groups (4a). A housing (9) separate from and releasably securable to the printing station (1) is formed of a lower housing part (9a) within which the transverse-displacement drive (6) is mounted and an upper housing part (9b) that is contoured to define the collection tray (7). Slide guides (14a, 14b) carried on the bottom (13) of the upper housing part (9b) on both sides transverse to the direction (5) of sheet delivery cooperate with guide ledges (25, 26) on the lower housing part (9a) for guided transverse reciprocation of the upper housing part relative to the lower housing part.
