Patent DE-3527675-A1 (DE)
Title: Damping circuit for overvoltages (snubber)
Inventor: FLECK MICHAEL DIPL ING
IPC: H03K17/732
Filed: 1985-08-01
Abstract: To damp switching overvoltages during the turning-off of a controllable semiconductor switch (for example a GTO), the usual damping circuit of a capacitor in series with a diode, with which a resistor is connected in parallel, which is connected in parallel with the semiconductor switch, is supplemented by the series circuit of a further diode - and possibly a resistor - with a further capacitor which is charged up to a limiting potential for the overvoltages via a resistor. If overvoltage peaks still occur across the first-mentioned capacitor, these flow away via the additional diode into the additional capacitor which is dimensioned in such a manner that, as a result, the limiting voltage to which it is charged up via the resistor does not significantly increase and the peak voltage occurring at the switch is thus limited to this value (Figure 1a). <IMAGE>

Title: Dividing-up installation for plate-like workpieces
Inventor: MARXGUT BERNDT
IPC: B27B31/00
Filed: 1986-03-07
Abstract: In a dividing-up installation for plate-like workpieces having a longitudinal saw (10), the supporting table (9) arranged in front of the latter is equipped with two groups of rollers (3, 6) which are in each case freely rotatably mounted. One group is mounted freely rotatably about fixed axes of rotation, these axes of rotation lying parallel to the cutting plane (11) of the longitudinal saw (10). The rollers (6) forming a second roller group are mounted such that they can be lifted and lowered relative to the rollers (3) and, moreover, are arranged between the latter in such a way that the imaginary extension of their axis of rotation intersect at a point. This point lies in the lateral region of the supporting table (9) and on the part thereof facing away from the longitudinal saw (10). A lever arm (7) is mounted horizontally pivotably above the supporting table (9) and the pivot axis (8) of this lever arm (7) contains the intersecting point of the imaginary extensions of the axes of rotation of the liftable and lowerable rotors (6). Charging devices and transporting carriages (18) complete the installation. By alternate lifting and lowering of the rollers (6) and by alternate actuation of the pivotable lever arm (7), it is possible to pivot the plate-like workpieces (4) in each case through 90 DEG  on the supporting table, as a result of which the working sequence during the dividing-up of a plate-like workpiece is simplified, when one or more head cuts have to be made in the workpiece. <IMAGE>

Patent DE-3709798-A1 (DE)
Title: Multipart screw
Inventor: KROKSNES FINN DIPL ING
IPC: B29C48/64
Filed: 1987-03-25
Abstract: Multipart screws, in particular extruder screws for the processing of rubber compounds, plastics or the like are occasionally designed such that a part of the screw, specifically the discharge part, is exchangeable. To achieve the advantages of exchangeability of screw parts, in particular the possibility of varying the geometric design and increasing the transmissible torques with respect to a solid screw, also in the feed region, the internal shaft (10) of the screw (2) is to be designed in its part lying behind the feed zone (6) of the extruder, as a screw shank (3) with a larger shaft diameter than the feed zone (6). From the feed zone (6) forwards, the internal shaft (10) only picks up the torque from the screw sections (16, 21) disposed downstream. The screw section (11) allocated to the feed-zone region is connected in a rotationally fixed manner only to the screw shank (3). The total torque is thus subdivided into two portions which are brought together only in the region upstream of the feed zone (6) which is unweakened by screw flights (14). <IMAGE>
Patent DE-3710858-A1 (DE)
Title: Ball valve
Inventor: MATEJA ERNST DIPL ING
IPC: F16K39/06
Filed: 1987-04-01
Abstract: In a ball valve for hydraulic systems, the plug (9) is mounted in the two sealing washers (16) not by its seating, but by an additional axle (7) or shaft (8). This renders ineffective that sealing washer (16) remote from the pressure side when it is in the closed position. All the force resulting from the fluid pressure is absorbed by the axle (7) or the shaft (8). Adhesion requiring a "tear-off force" no longer occurs between the plug and the sealing washer. The two sealing washers (16) are preferably in the form of plungers arranged in cylindrical (15) housing components (14). The latter are screwed advantageously into a main housing (1). <IMAGE>
