Abstract: A staple wire cutting element (4) is mounted displaceably on a stapling device (1) in which staple wire segments are shaped into a staple and driven into a sheet stack. A control lever (8) that is in engagement with a radial cam unit (6) engages the cutting element (4). The radial cam unit (6) is driven via an overrunning clutch (10), one end of which has a gear (11) which is fixed to the radial cam unit (6) and engages into a gear (5b) of a stepping motor (5). The other end of the overrunning clutch (10) has a gear (12) which is fixed to a transport wheel (13) for staple wire transport. A gear (27), which is mounted displaceably along its rotation axis and is mounted rotatably about the same rotation axis as the gear (5a), engages into the gear (12). The gears (5b, 27) are equipped at their sides facing one another with tooth sets (28).

Abstract: A staple wire supply roll is positioned on a threading-in device that can be moved out of a stapling apparatus, and the leading end of the wire is transported by means of a thread-in transport device, through a flexible guide tube, to a stapling device. A sensor positioned on the stapling device signals the end of the threading-in operation when the leading end of the staple wire passes by. By pushing the threading-in device into the apparatus, the staple wire transport device of the stapling device is set in motion, as a result of which the leading end of the staple wire is transported to a location which positions the leading end of the wire in device. The staple wire is transported, in accordance with the thickness of the sheet stack measured by a sensor, by a stepping motor, which at the same time drives a radial cam unit.

Abstract: A delivery unit (1) of a copying apparatus is equipped with a paper delivery tray (2), provided in a top cover (4). The paper delivery tray (2) consists of at least one inclined delivery surface (2a, 2b) for a sheet stack, an output slot (10) formed by paper output rollers (8), and a paper contact surface (6) arranged after the output slot (10). A bar (12), which fits around the output slot (10) and can be pivoted onto the sheet stack (5) located on the delivery surface on the basis of a signal form the copying apparatus, is provided in a wall (7) of the paper delivery tray.

Abstract: A device for electrolytically recovering metal, in particular silver, from a photographic processing solution, said device having an anode located in a recovery chamber and a movably arranged cathode as well as a scraper for removing metal, in particular silver, deposited on said cathode. For the purpose of electrolytically depositing metal (17), cathode (12, 32, 42) is held stationary in its operating position within the solution (16). For removal of the metal, the metal-loaded cathode (12,32, 42) is moved out of its operating position within the solution (16) and is brought into engagement with the scraper (14, 20, 34, 44) arranged outside the solution (16). Subsequently, the cathode (12,32, 42) freed from metal (17) returns to its operating position within the solution (16) for a repeated electrolytic deposition of metal (17).

Abstract: In a film loading device, a plurality of supply magazines of different sizes are arranged horizontally one above the other. The removal sides of the supply magazines are staggered such that the largest supply magazine is arranged at the top of the device and each following, smaller supply magazine is staggered backwardly below. An endless conveyor belt with projections is arranged opposite to the removal sides of the supply magazines, said belt being in an inclined position corresponding to the inclination of the staggered arrangement of the magazines. The conveyor belt extends from the upper most supply magazine down to a cassette unloading and reloading station disposed below the supply magazines. At the side of the conveyor belt which faces away from the supply magazines, a drive and control device of the film-loading device is positioned.

Abstract: In a guiding device for aligning sheets of paper (13) being stacked in a stacking tray (11) to which the sheets (13) are fed by means of a feeding mechanism (3, 5), deflectable fenders (25 and 26) are provided which are suspended from a mounting element (27) located above the path of the sheets and which extend into the path of each sheet (13), and are contacted and deflected by such sheet. The deflected fenders (25, 26) exert pressure on the contacting surface of the sheet so that the sheet when released by the feeding mechanism (3, 5) enters the stacking tray (11) from above in a controlled manner. At least one (26) of the fenders (25, 26) takes the form of a loop consisting of a flexible web (28) whose two ends are united and suspended from the mounting element (27). As suspended, the flexible loop makes and maintains large area contact with the sheet until stacked resulting in sheets aligned laterally with respect to one another in the stack.

Abstract: An apparatus for facilitating depositing copy sheets in a collecting bin (6, 15) which, in the sheet entry direction, is arranged in a downwardly inclined position and is provided with a stop member (14) associated with the leading portion of the sheets. The trailing portion of the sheets is associated with guide element (19, 30) directing the incoming sheets onto the top of the sheet stack already deposited. Above the sheet stack (23, 23a) rollers (22, 26) are arranged which are driven in sheet entry direction and associated with the trailing portion of the sheet and whose surface area facing the sheet stack (23, 23a) lines beneath the entry plane of the sheets defined by the guide elements (19, 30) to the extent that also in the case of curled sheets it confines the top of the sheet stack (23, 23a) in a position beneath the sheet entry plane keeping the feed path open.
