Title: Method and device for determining the pull-in and release time of the tappet of a solenoid injection valve
Inventor: HUETTEN HEINRICH
IPC: F02M65/00
Filed: 1988-02-05
Abstract: In a method and device for determining the pull-in and release time of the tappet of an injection valve of an internal combustion engine, the acceleration peaks caused by the tappet striking on stroke limit stops in the upper and lower limit position are absorbed without interference in the valve and fed as acceleration signals to an actual/set point comparator, by means of which set-time deviations between a signal, produced by a voltage pulse triggering the tappet lift, and the acceleration signal produced by the upper and the lower acceleration peak are determined.

Title: Wheel flange-guided transport system
Inventor: PIRAGS SIEGFRIED
IPC: B61D11/00
Filed: 1988-03-29
Abstract: The transport system has a wheel flange-guided transport vehicle 1 which can be moved on two travel rails 4 of a track element 5. In the region of steep sections of track, two guide rails 6 are arranged on the track element 5 parallel to the travel rails 4, guide arms 9 which are attached to the transport vehicle 1 by means of brackets 10 engaging in the said guide rails 6. At the ends of the guide arms 9, guide rollers 8 which engage in the guide rails 6 and thus positively guide the transport vehicle 1 on the track element 5 are rotatably mounted. By means of this protection against derailing, even steep sections of track can be travelled over and braking forces which exceed the transport vehicle's own weight can be applied without the risk of derailing. For use in level sections of track where the transport vehicle 1 runs exclusively in a wheel flange-guided fashion, the guide arms 9 can be pivoted upwards. <IMAGE>
Patent DE-3817156-A1 (DE)
Inventor: ECCLESTON LARRY EDWARD
IPC: G01R15/12
Filed: 1988-05-19
Abstract: Calibrating errors of a variable gain amplifier (12) used in an AC calibrator or AC meter are determined for a gamut of frequencies by adjusting a variable resistor (13, 14) in discrete steps and applying (16, 21, 27) a variable amplitude signal to the amplifier so that the amplifier produces a gamut of output signals of predetermined nominal values. These signals are detected (24, 23) and the actual values are compared (17) with the nominal values to derive a calibrating error for each resistor value. A gamut of variable frequency, constant amplitude signals is then applied (22, 27) to the amplifier while the gain is constant and the amplifier output for each frequency is compared with the output at a reference frequency at which the output is unaffected by reactive components in the circuit. The amplitude versus frequency response indication of the amplifier is then modified by the derived calibrating error signal. The calibrated amplifier is used in a voltmeter or AC calibrator so that the amplifier output is modified as a function of input frequency and gain setting. <IMAGE>

Title: Device for producing a measuring force for a length measuring instrument
Inventor: SIEPMANN ULRICH DIPL ING
IPC: G01B3/00
Filed: 1988-05-28
Abstract: A device for producing a measuring force for a length measuring instrument is provided. It can be applied both in height-measuring instruments and measuring machines as well as in digital hand-held measuring instruments. The aim is a simple and small design of the device. Precisely reproducible measurement forces can be set without thereby causing an uneven movement of the carriage or influencing the measurement force.   Two fixed stops (9, 10) project on a measuring head (1). Located between these two stops (9, 10) is a stop (13) which is connected to a driven, rotating traction means (4). A stop (12) surrounds the stop (13) and a biased spring (11). A spring (14) is biased over the stop (12) between the two stops (9, 10). <IMAGE>

Title: Motor car with manual gearshift transmission
Inventor: MANNES WERNER
IPC: B60W30/18
Filed: 1988-07-14
Abstract: Motor vehicle with manual gearshift transmission. In order to avoid a rigid coupling of the engine of the motor vehicle to its driven wheels by way of the manual shift transmission and hence unfavourable reactions in braking of the motor vehicle and in load reversals, a shiftable and controllable clutch is inserted into the input shaft of the shift transmission, disengagement of which can be controlled in the gearshift sequences and which is adjustable in its transmission torque as a function of the output speed of the manual shift transmission or the speed of a vehicle part driven thereby. If, for example for design reasons, the drive torque of the manual shift transmission cannot be introduced by way of the shiftable and controllable clutch, the shiftable and controllable clutch can be bypassed by a freewheel mechanism locking in the drive direction of the input shaft.

Title: Suction-cleaning tool for floor coverings and the like
Inventor: WOERWAG PETER
IPC: A47L9/04
Filed: 1989-02-14
Abstract: Known suction-cleaning tools are operated together with a suction-cleaning apparatus, and a suction air flow courses through them, simultaneously driving an air turbine for the rotating drive of a cleaning brush. The dirt load which flows through the air turbine with the suction air flow leads to considerable deposits, disruption and functional impairment in the air turbine. According to the invention, provision is made for the air turbine to be drivable by the exhaust air flow, so that even in the case of long periods of use functional impairment of the air turbine does not occur. Suction-cleaning apparatuses.

Title: Polycentric above-knee prosthesis
Inventor: KRIEG BERND
IPC: A61F2/60
Filed: 1989-03-07
Abstract: The new polycentric above-knee prosthesis having a closed kinematic four-bar mechanism avoids advancement of the knee relative to the lower leg on bending forward, has an improved cosmetic appearance in the bent state, manages without clamping sleeves and adjustment adapters despite being fully adjustable in the sagittal plane, is produced with relatively small construction costs, is lighter than polycentric solutions, can be controlled more easily by the stump forces that are still present, lifts the tip of the foot in the swing-through phase and can be produced in shell design or skeleton design with foam lining (48). These properties are achieved in that the upper coupling is formed, as previously, by the knee member (1), whereas the lower coupling is formed by the foot moulding itself, so that the upper two axes (2, 3) are allocated to the knee member (1) and the lower two axes (5, 7) are allocated to the foot moulding (6). The front link (8, 45) forms the lower leg and receives the rear link (4) in a cavity (8b). The rear link extends between the rear hinge point (3) of the knee member (1) and the rear hinge point (5) of the foot, and the upper rear hinge point (3) is arranged on a straight line extending obliquely downwards by 40 to 50 degrees from the front upper hinge point (2). <IMAGE>

Title: Bend setting method for workpiece shape
Inventor: WAKAHARA TAKASHI
IPC: B21D5/02
Filed: 1989-08-04
Abstract: Successive impact places and bending points are determined using the previously given workpiece shape data. Determines the bending points at which prebending is necessary and assigns identification codes and smaller bending angles for the prebending at the preceding determined bending points. An obstruction test unit (205) simulates the bending process of the workpiece (W) based on the input data from the bending process setting unit (203) and carries out a monitoring operation with regard to any hindrance between the workpiece (W) and the top and bottom press parts (7,9) taking place.  If a hindrance to the bending operation is established, a prebending setting unit (207) determines the bending point (P', P") where the prebending is necessary to prevent the obstruction and gives a prebending identification code and sets the required bending angle.
