Patent DE-3901966-A1 (DE)
Title: Valve drive for a reciprocating valve with mechanical compensation of the valve play
Inventor: VOIGT DIETER DIPL ING
IPC: F01L1/22
Filed: 1989-01-24
Abstract: A roller drag lever (4) is equipped with means for mechanically compensating valve play, which means contains as an essential component at least one roller pin (8, 9) which is eccentrically mounted by means of a disc (7), for a roller (10, 11) which rests on a rotating cam (12), the disc (7) being received in a frictionally engaging manner in a recess (5) of the roller drag lever (4); the frictional engagement is ensured to a limited degree by a pivoting bush (6) which is rigidly connected to a fork lever (15) whose stops (16, 17) enclose the free end (1) of the valve shaft (2) in the pivot plane of the drag lever (4). By suitably selecting the eccentricity (e) of the roller pins (8, 9) and of the direction of rotation of the cam (12) with respect to the eccentricity (e) it is ensured that during the opening stroke of the valve the stroke length of the valve is shortened; on the other hand, the rotating roller (10, 11) brings about elimination of the play after the closing stroke by means of post-pivoting of the roller pin (8, 9) so that the roller (10, 11) always rests on the cam (12) (Fig. 1). <IMAGE>

Title: Pin-setting machine for connecting two cables to a common fitting
Inventor: BRANDENBERGER WERNER
IPC: H01R43/052
Filed: 1989-04-04
Abstract: Two cable ends (1, 2), which are arranged parallel to one another and side by side in a horizontal plane, are pivoted in this plane to such an extent that that cable (2) which is located at the front in the pivoting direction rests against an insertion curve (10), which falls away downwards, of an alignment bracket (11). The cables (1, 2) are subsequently lowered downwards, the movement of that cable (2) which rests against the insertion curve (10) being delayed by friction, and said cable (2) moving above the cable (1), which is initially lowered without any friction, during the movement, as a result of the insertion curve. A vertical directing edge (10) which is adjacent to the insertion curve (10) then ensures that the two cables (1, 2) are located exactly one above the other, in which position the stripped ends of said cables can be inserted from above into a clamping holder (terminal holder) of a fitting (7). <IMAGE>
Patent DE-3911887-A1 (DE)
Inventor: BUSCHMANN ULRICH DIPL ING
IPC: B41J33/22
Filed: 1989-04-07
Abstract: In a printer, a drive motor, a drive roller arranged on the shaft of the motor, a reversal roller in spaced relation to the drive roller, and an elongated drive belt trained about the drive and reversal rollers form a tensioning device, the belt being fastened at its ends to a print-head carriage for selectively displacing the carriage in the forward and reverse directions along and relative to a printable substrate support roller or base. The reversal roller is carried in a carrier housing which movably and cooperatively engages a spring-loaded tensioning wedge for maintaining the elongated drive belt in a predetermined tensioned or stretched relation. In order to avoid the need for a separate or specialized drive motor and an additional drive belt for advancing an inked printing ribbon, the drive force for the inked-ribbon drive shaft is derived from the reversal roller which, in the normal operation of the printer, is rotatable in opposite directions for selectively positioning the print-head carriage along the printable substrate support. For this purpose, a clutch member is interposed between the reversal roller and a gearwheel associated with the inked-ribbon drive shaft, the clutch member being longitudinally movable into coupled and uncoupled relations with the inked-ribbon gearwheel as a function of the direction of rotation of the reversal roller.

Title: Uretero-renoscope and endoscope
Inventor: VILMAR WOLFGANG DR
IPC: A61B1/313
Filed: 1989-05-19
Abstract: A known uretero-renoscope comprises a tubular catheter body having a number of channels, one of which serves as optics channel (fibre optics), and further channels which serve as working channels for passing through, in particular, surgical instruments or as rinsing channels for passing through irrigation liquids. Disadvantages: in particular, not enough channels, relatively large channel diameter, insufficient flexibility of the catheter body. In the novel uretero-renoscope the catheter headpiece (2) and the catheter body (3) are designed with at least four channels. For formation of the channels (20-23) the catheter body (3) has an essentially round cross-section and is provided in its interior with two partition walls (17, 18) which cross each other essentially at right angles. In addition to the optics channel, there are at least three free channels which can selectively be used as separate rinsing channels and/or as working channels. A corresponding design is also provided for a catheter in the general sense. Advantages: flexible renoscope or flexible catheter with multi-channel design, sufficient stiffness of the catheter body, free choice of the use of at least three free channels, small channel diameters, many options for surgery and diagnosis. <IMAGE>
