Inventor: NAGEL PETER
IPC: B24B33/02
Filed: 1987-11-10
Abstract: In a honing tool (12) which machines a workpiece bore (16) in only one metal-removing stroke, the honing tool length, in particular the length in front of the calibrating zone (41) determining the finished size of the bore, is to be shortened. For this purpose, a guide element (13) is attached to the workpiece (14) in an aligned manner, which guide element (13) assumes the initail guidance so that the tool can be designed without a front guide zone and can start with the cutting zone (40) right at its lower end. <IMAGE>

Title: Diesel injection by electro-hydraulically operated cylindrical slide valves
IPC: F01N13/08
Filed: 1988-01-26
Abstract: An injection method for diesel engines is proposed, the electro-hydraulically controlled injection valves of which allow the rate of injection to be constantly optimised during operation, the corresponding engine parameters being continuously determined by means of sensors and the rate of injection being, as a result, constantly adjusted to an optimum degree. The injection system is fed from a high stationary pressure, nevertheless varying with the engine parameters. The injection quantity is thereby determined every second and controlled by a central electronics unit. In addition, it is decided here whether fuel is injected by single or multiple injection. The achievement of minimum combustion noise or minimum soot formation are in particular described here as possible control systems.

Title: Axial-rotary piston engine with sinusoidal stroke path
IPC: F01B9/06
Filed: 1988-03-15
Abstract: Axial-rotary piston engine with sinusoidal stroke path. The stroke path is sinusoidal (10) and has the function: stroke = H/2<*> sine (alpha> Where H is equal to the overall stroke and alpha extends from 0 to 720 degrees over 2 full sine periods.

Title: Window-washing system of a vehicle and method of washing the windscreen of a vehicle
Inventor: HOFFMANN HEINRICH
IPC: B60S1/48
Filed: 1988-07-06
Abstract: The invention proposes a window-washing system of a vehicle, with a pump (9) which can be brought alternately into connection with spray nozzles (4a, 4b), which system is characterised in that two spray nozzles (4a, 4b) are provided which are both directed onto the windscreen (1) of the vehicle. The method of washing the windscreen of a vehicle, in which two spray nozzles are directed onto the windscreen, is characterised in that the spray nozzles are operated alternately. The invention does not need a high pump pressure for cleaning the windscreen and as a result of the lower power required the overall size of the pump can hence be reduced. Due to the continuous increase and decrease in the jet a larger wetting area of the windscreen is furthermore obtained; since in each case only one spray nozzle is operated the quality of the jet is, moreover, better. <IMAGE>

Title: Temperature compensation circuit for a Hall generator
Inventor: PRETZLAFF VOLKER
IPC: H01L43/04
Filed: 1988-08-13
Abstract: A temperature compensation circuit for a Hall generator having a permanent magnet, in which a constant current source is controlled by a temperature-dependent resistor and the output voltage of the Hall generator can be varied by a temperature-dependent addition voltage. The technical problem is to construct the temperature compensation circuit in such a way that it is possible to adapt to different types of Hall generators and to adapt to manufacturing tolerances. The constant current source is constructed as an operational amplifier (OP2) whose input is connected to a divider cap of the temperature-dependent resistor (R5). A regulated input voltage is connected to earth (frame) via the temperature-dependent resistor (R5). The temperature-dependent residual (relevant) voltage of a diode (D2) is tapped as the addition voltage and added to the output voltage of the Hall generator (4). <IMAGE>

Title: Transport securing device for objects sitting on supports
Inventor: JANSSEN WERNER
IPC: B25B5/04
Filed: 1988-10-28
Abstract: In the case of a transport securing device designed according to the invention for objects (1) sitting on supports (3, 4), at least one support (4) is coupled to a securing lever (13) which is pivotably mounted at a pivot (M) and in its securing position engages over the region (6), lying on the support, of the object (1) to be secured against unintentional lifting/tilting. In this arrangement, an engaging part (15) of the securing lever (13) and its pivot (M) are assigned to one another in such a way that, by means of a force (F) acting on the securing lever (13) as a result of the lifting/ tilting object (1), a torque is generated which holds the securing lever in its securing position. By virtue of this particularly advantageous utilization of the force acting on the securing lever (13) in the event of tilting, the transport securing device can be of simple constructive design and nevertheless have an operationally reliable method of functioning. <IMAGE>

Title: Infrasound detector
Inventor: WEILAND HEINZ-PETER
IPC: G08B13/20
Filed: 1989-04-03
Abstract: Infrasound detector for monitoring a space with a sensor for converting pressure fluctuations which occur in the space into an electrical sensor signal which consists of a DC signal and an AC signal which is superposed on this DC signal and is a function of the pressure fluctuations, having an amplifier device for frequency-selectively amplifying the sensor signal and having an output stage for outputting a switching signal when the amplified AC signal exceeds a preselected switching threshold. To avoid unwieldy capacitors, which have large capacitances, and rectifier circuits, the amplifier device is constructed from amplifier stages, which are only DC-coupled in such a manner that in its output (E) a first signal appears which is derived from the sensor signal and consists of a first DC component and a first AC signal superimposed on said DC component. The switching threshold is defined by the first signal and a second signal which, in comparison to the first signal, has a second DC component of different size. The output stage is constructed in such a manner that the switching signal appears only when the amplitude of the first AC signal becomes larger than the value which corresponds to the second signal (Fig. 1). <IMAGE>

Title: 2 and 4-stroke internal combustion engine for hydrocarbons with internal mixture formation and subsequent laser ignition, free of pollutant emissions
Inventor: BACKHAUSS ROLF
IPC: F02P23/04
Filed: 1989-04-05
Abstract: The said 2 and 4-stroke internal combustion engines are simple in the construction of the fuel-air mixture formation with subsequent ignition and are necessary for our environment. To recapitulate and to add to what has been said I would like to state the following here.     1. Icing cannot occur in the intake manifold. 2. The internal mixture formation is a necessary prerequisite for efficient combustion. 3. The injector through which coolant flows and the pressurised fuel with constant flushing of the fuel chamber, apart from the injection itself, form the prerequisite for the introduction of volatile fuels into the combustion chamber without prior carburation. 4. With its linear beam into the fuel jet, the laser ignition always allows ignition to be initiated, even with the leanest fuel-air mixture delivered to the overall combustion chamber. 5. Monitoring for too rich a fuel-air mixture is provided by the air mass flow sensor and the lambda probe on the control module, so that the internal combustion engine is independent of atmospheric air pressures. The said internal combustion engine is therefore efficient even at altitudes of 5000 metres.   It should also be mentioned that the said internal combustion engines will have a significantly improved fuel consumption.

Patent DE-3941473-A1 (DE)
Inventor: HAUSSECKER WALTER DIPL ING
IPC: G01R33/06
Filed: 1989-12-15
Abstract: The proposal is for a process for testing a sensor system consisting of a Hall sensor with a digital signal output (20) and a control magnet movable in relation thereto and a Hall sensor as a device for implementing the process. To this end, the magnetic flux density is detected and assessed via an additional analog signal output (19) of the Hall sensor. Besides the digital position signals it is thereby possible by means of a single sensor to achieve self-checking on whether the distance between the Hall sensor and the control magnet is correct and whether digital position signals can still be expected to be reliably generated.
