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 bearing part (7 or 20) is arranged on a continuously driven drive shaft (4) arranged parallel to the transport plane of a sheet (6) to be aligned and at right angles to the sheet transport direction (A), on which bearing part an aligning roller (5 or 15 or 16 or 18 or 21) at an oblique angle (.alpha.) to said sheet transport direction (A) is rotatably mounted. The bearing part (7 or 20) is stationarily secured against turning and moving, and is freely passed through by the drive shaft (4). The aligning roller (5 or 15 or 16 or 18 or 21) is mounted rotationally symmetrical to said drive shaft (4).The drive shaft (4) and the rotatably and obliquely mounted aligning roller (5 or 15 or 16 or 18 or 21) are connected to one another by a positive coupling (5a, 8 or 14, 15a, or 17 or 19).Several bearing parts (7 or 20) with aligning rollers (5 or 15 or 16 or 18 or 21) can be arranged on the drive shaft (4) and be driven by one and the same drive shaft (4).

Abstract: At the free end of a pivotable arm (1) of an aligning device, two wheels (4, 6) of identical diameters are mounted for independent rotary movement, such wheels being driven by a shaft (2). The wheels (4, 6) are each eccentrically offset from the axis of rotation (2a) of shaft (2) by the same amount (26, 27)and are uniformly spaced about said axis. With respect to a plane running perpendicularly to the axis of rotation (2a) of shaft (2), each wheel (4, 6) is mounted at an acute angle (.alpha.) such that adjacent wheels (4, 6) are arranged in a V-shaped configuration. The eccentrically (26, 27) and the angular position (.alpha.) of the wheels (4, 6) are related such that the contact surface (4b and 6b) of each wheel (4 and 6, respectively) resting on the sheet to be aligned carries out a movement transversely to the sheet-entrance direction (A) and towards the lateral limiting wall (18).

Abstract: In a collecting tray (1) having a lateral limiting member (6) and an end-side abutment (3), a driven aligning wheel (16) is arranged on a pivotally mounted, spring-biased tube (9 and 10 respectively). The abutment (3) is pivotally mounted on an arm (3a) and connected with a lever (4) which includes a pin (4a) adapted to support tube (9). When abutment (3) is pivoted to its opening position, aligning wheel (16) is lifted off sheet stack (24) so that the stack can be removed unimpededly. The aligning wheel (16) is conically shaped and pivotable from a position in which it is spring-biased towards the lateral limiting member (6) to a position directed at the front abutment (3) such that when a sheet has been laterally aligned, aligning wheel (16) is caused by the increasing friction to pivot in opposition to its spring bias to the position direction at the front abutment (3).

Abstract: A device for limiting rotary movement in two directions comprising a housing (18) having a wall (17). A first stationary component (10) is attached to the wall (17) of the housing (18), the first stationary component having an arcuate segment (11) defined by lateral surfaces (11a, 11b) limiting the arc length thereof. A shaft (14) is rotatably mounted in the first component (10). A second component (20), also having an arcuate segment (21) defined by lateral surfaces (21a, 21b) limiting the arc length therof, is attached to the shaft. The first and second components (10, 20), respectively, have the same shapes and sizes and each of them is provided with a bearing (12, 22) which defines a bore (12a, 22a) and is molded on the arcuate segment (11, 21). Pins (11c, 21c) are positioned, respectively, to extend from oppositely directed faces of the arcuate segments (11, 21). The lateral surfaces ( 11a, 11b; 21a, 21b) of the first and second components (10,20) form abutments acting on both sides.

The catheter is also coated with an external protective layer composed of a hydrogel.

Abstract: An apparatus for infusion of liquids into human or animal bodies which comprises a liquid reservoir having a reduced-pressure generating means associated therewith and an active delivery-dosing means, such as a roller pump, operationally coupled with the reservoir and with an outflow catheter having outflow opening within the body being infused. The reduced-pressure generating means, such as a volatile fluid, for example, a halogenated hydrocarbon, maintains a pressure at the point of connection between the reservoir and the active delivery-dosing means at a reference value which is lower than the pressure prevailing at the outflow opening of the outflow catheter.

Abstract: To provide for extended true running of the distributor shaft and prevent wear on relatively movable mechanical components within the distributor, such as a shaft and bearings, a centrifugal spark advance/retard mechanism, or the like, the relatively movable parts are included in the lubricating circuit of the engine, for example by being connected to the pressure lubrication system of the engine or located to be exposed to oil mist in the engine compartment and arising upon operation of the engine, so that the relatively movable parts are constantly lubricated by the engine lubricating system.
