Patent DE-3720380-A1 (DE)
Title: Regulating valve
Inventor: YASUI KATSUAKI
IPC: F16K1/22
Filed: 1987-06-19
Abstract: A throttle valve comprises a valve housing (1), which forms a flow path and in which a plate-like valve element (3) is held rotatably by means of a valve shank and, on the circumferential edge of the outflow side of the section of the valve element on the outflow side there is provided a deflecting surface (4) in such a way that the angle (alpha) formed between the outer surface of the central section of the deflecting surface and the inner side of the valve housing (1) is equal to 0@ to 15@ when the flow path is fully closed by the valve element. Since the fluid flow passing through between the valve element (3) and the inner surface of the valve housing (1) does not widen abruptly but is widened gradually between the deflecting surface and the inner surface of the valve housing, the flow velocity between the deflecting surface and the inner surface of the valve housing is reduced, so that the pressure is recovered. Subsequently, turbulence on the outflow side of the valve element is suppressed, thereby reducing the noise of the throttle valve. <IMAGE>

Patent DE-3738241-A1 (DE)
Title: Electrohydraulic device for the load-independent control of a volume flow in a manner proportional to an input signal
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F15B13/16
Filed: 1987-11-11
Abstract: An electrohydraulic device (10) for load-pressure-independent flow control with a directional function is proposed, in which the functions of the measuring throttle, the control throttle and the directional control are realised in a space-saving manner on one axis. A volume flow sensor (47), which undertakes the function of measuring throttle, with a piston (52) loaded by a measuring spring (51) is arranged in a hollow longitudinal plunger (26), which undertakes the directional control. The difference signal from two travel pick ups (45, 46) fastened to the housing and coupled to the longitudinal plunger (26) and the piston (52) yields the effective piston stroke and thus a measure of the quantity of the respective volume flow, which is used as control variable in the electrohydraulic control loop (63), the longitudinal plunger (26) automatically carrying out the function of the control throttle. <IMAGE>

Title: Method for error detection in video signals
Inventor: WENGER HEINZ
IPC: H04N17/06
Filed: 1987-12-15
Abstract: A method for the fully automatic measurement and analysis of envelope-curve fluctuations of the carrier frequency of video signals which are stored on a magnetic recording carrier in the form of a tape, is achieved by the fact that the rectified amplified carrier frequency signal charges up a capacitor C1 via a timer controlled by a 25-Hz field switching signal, and, at the same time, a capacitor C2 via a voltage divider, then the values stored in C1 and C2 are continuously recharged when the envelope curve changes, whereupon, after the measuring time has elapsed, the attenuated maximum value stored in C2 exceeds the minimum value stored in C1, this is evaluated by a comparator (3) and measured as error in a recording device (Figure 2). <IMAGE>

Patent DE-3800193-A1 (DE)
Title: Reversing valve which can be used as a resetting valve
Inventor: VOSS RICHARD
IPC: E21D23/16
Filed: 1988-01-07
Abstract: A resetting valve provided for underground mining works continuously and quickly and has really favourable overall dimensions when a reversing valve sealing on two sides via two sectional pistons and serving as a valve piston is allocated to the pump connection and an adjustable pressure-relief valve is allocated to the connection for the piston area. The spring space of the pressure-relief valve is connected to a valve space in which a double-acting piston acting on the sectional piston of the reversing valve and having a plunger is displaceably arranged. This double-acting piston has different pressure areas so that it is ensured that it is moved in each case against the sectional piston so as to open the latter when the pressure in the pressure space is equal, so that the pump line is then continuously connected to the piston area of the support prop to be set or the set support prop. The pressure space of this piston can be connected via an additional control piston to a bore which is formed in the housing wall so that, during the withdrawal of the support prop, the increased pressure behind the double-acting piston can be removed safely and simply. In the process, only so much pressure as necessary is removed each time so that pressure fluid always remains in the system and the resetting valve can operate correspondingly quickly and for a short time. <IMAGE>

Title: Device for adjusting the inclination of a keyboard for typewriters or office machines of similar design
Inventor: KITTEL ARTHUR DIPL ING
IPC: B41J5/10
Filed: 1988-07-15
Abstract: To adapt the keyboard to the ergonomic conditions of an operator or of the workplace, it is already known to adjust the inclination of the keyboard. The known devices for adjusting the inclination of the keyboard are still comparatively expensive and are not simple to handle for every operator. These disadvantages are eliminated according to the invention in that the keyboard (2), mounted at one longitudinal edge (3) so as to be pivotable about an axis of rotation (4), has a push button (36) by means of which a drive motor (6) can be activated in order, via a reducing gear, to actuate adjusting means for infinitely variable pivoting and thus for adjusting the inclination of the keyboard (2). By actuating the pressure switch (36), the electric circuit to the drive motor (6) can be closed for the continuous drive thereof, the adjusting movement being interrupted when contact is broken in the electric circuit. As a result, infinitely variable adjustment of the inclination of the keyboard (2) can be achieved in a very simple manner. <IMAGE>

Patent DE-3835521-A1 (DE)
Title: Apparatus for comminuting a residual film grid
Inventor: KIEFER GUENTHER
IPC: B29B13/10
Filed: 1988-10-19
Abstract: The invention relates to an apparatus by which a residual film grid of a thermoforming or packing machine is comminuted by successive longitudinal and transverse cuts. In this case, the apparatus is constructed in such a way that the longitudinal and transverse cutting knives are simple to produce and to regrind, without transporting problems arising with respect to guiding the longitudinally cut regions to the transverse cutting point. This is achieved by the two transverse cutting knives being designed with a straight cutting edge, and by individual longitudinal cutting knives, projecting beyond the cutting edge and in the form of a narrow blade, being arranged in the region of the movable transverse cutting knife. The fixed transverse cutting knife has corresponding grooves at these points. The longitudinally cut piece of the residual film grid in this way lies directly before the transverse cutting line and if individual parts are already produced by the longitudinal cutting, these are pushed over the transverse cutting line or even fall over the latter if the residual film grid slopes downwards in the cutting region. <IMAGE>
