Patent DE-4210564-A1 (DE)
Title: Distributor pump of fuel injection system for IC engine esp. for motor vehicle - has piston with stroke and rotational movement synchronised with engine having at least one control bore leading to its circumference
Inventor: DAHLMANN GERD-UWE DIPL ING
IPC: F02M41/12
Filed: 1992-03-31
Abstract: The pump piston carries a regulating slide valve (6) making contact with a power adjusting element, such as an accelerator pedal, which is movable between a first axial position taken up during the injection operations, in which it covers the control bore, and a second axial position, in which it frees the control bore to the ending of the injection operations across a controlling edge (12). A control unit operates a slider on the pump piston (1) as well as a unit contg. a drive for the slider, with sensors for at least one engine parameter, for automatically influencing the injection operations depending on the engine parameters. The regulating slide valve (6) at the same time forms the slider, allowing its slide connection (7-10) for the power adjusting element rotary movements of the regulating slide valve (6). A drive (14, 15, 16) allows the sliding movements of the regulating slide valve (6). The control edge (12) of the regulating slide valve runs inclined to the circumferential direction. ADVANTAGE - Type distribution pump, which influences amount of injection by corresp. adjusting of end of individual fuel injection operations, esp. dependent on engine r.p.m. but also on any other engine parameter.  Permits low building cost.

Patent DE-4312631-A1 (DE)
Title: Method for digital communication
Inventor: STUHRMANN DIRK
IPC: H04M11/06
Filed: 1993-04-19
Abstract: A method is indicated for digital communication between two stations in which transmission units for sending and receiving digital signals are disposed. Before the start of the signal transmission, the transmission units of the two stations are first switched to different operating modes in which two defined identifiers which differ according to the operating mode are transmitted by the two transmission units. Only then is the transmission path switched to a transmission-capable condition. For the automatic definition of different operating modes for the two transmission units, the latter are first switched with any operating mode to standby mode by connecting them to a power source. Each transmission unit then checks which of the two defined identifiers is being transmitted by the respective other transmission unit. If both transmission units are set to the same operating mode, one of the transmission units is automatically switched over to operating mode after a randomly activated timeout period which is supplied by a timer which can be activated according to the random principle and which has at least two different timeout periods. The identifier received from the respective other transmission unit is again checked at least before the switchover.

Title: Arrangement for controlling hydraulic drives for power-regulated screw compressors
Inventor: KNODEL OTTO DIPL ING
IPC: F04C18/16
Filed: 1993-07-20
Abstract: The object of the invention is to remove the technical disadvantages and the expensive solutions for controlling hydraulic drives, preferably for power-regulated screw compressors, and to realise an arrangement for controlling a double-acting hydraulic drive with little technical outlay in a compact type of construction, preferably for direct attachment or fitting. The object is achieved in that, for the two connections of the double-acting hydraulic drive to be controlled, in each case only one seat valve, preferably operable with auxiliary power, is allocated, if required also with a different admissible operating pressure per connection. In the open state, the seat valve produces a connection from the connections of the hydraulic drive to the point of low pressure potential.

Title: Throttle valve control
Inventor: KAMEI SADAAKI
IPC: F02D9/00
Filed: 1994-02-24
Abstract: A throttle valve control is disclosed which is capable of reliably ensuring and maintaining minimum functioning of the continued locomotion of a vehicle under the power of the engine. A device (13) for sensing incorrect functioning detects a correct functioning of at least a first and second accelerator pedal sensor (20, 21) and an accelerator pedal switch (22) on the basis of first and second accelerator pedal actuation signals and an accelerator pedal output signal. A throttle valve opening control (14) forms a throttle valve control signal as a function of the first accelerator pedal actuation signal when the accelerator pedal sensors (20, 21) are operating normally and forms a throttle valve control signal on the basis of the output signal of the accelerator pedal switch when incorrect functioning of the first or second accelerator pedal sensor (20, 21) is sensed. <IMAGE>

Patent DE-4407002-A1 (DE)
Title: Catalytic converter heating device for internal combustion engines with a burner system
IPC: F01N3/20
Filed: 1994-03-03
Abstract: In heating devices of this type it can occur that the heating in a functionally impaired catalytic converter has no effect on the rate of conversion for the reduction of pollutants, so that virtually untreated emissions are discharged. The new heating device, on the other hand, has the characteristic feature that the catalytic converter is formed from two sets of catalysts, between which a catalytic converter chamber exists, that the burner exhaust gases flow into the catalytic converter chamber, mix there with the internal combustion engine exhaust gas and heat the second catalytic converter insert in the direction of flow. With the measures according to the invention a high pollutant conversion rate and a lower exhaust gas emission after engine cold starting are achieved, even in an already aged catalytic converter.

Title: Magnetooptical disc and disc drive for such a disc
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/10
Filed: 1994-04-15
Abstract: A magnetoopical disc system comprises a magnetooptical disc (101) and a disc drive. The magnetooptical disc drive provides a function of setting the form of a recording area using a short-wavelength laser beam, a test-recording function and a function of recording with a multiple pulse. The magnetooptical disc has a laminate layer structure, by which a high signal-to-noise ratio can be achieved and by which the heat conduction can be stabilised. The magnetooptical disc drive with setting function for the form of the recording area using a short-wavelength laser beam and a test recording and also with the multi-pulse recording function is organically coupled to the magnetooptical disc with laminate layer structure and stabilised heat conduction, in order that the disc and the disc drive are one unit, thereby producing a magnetooptical disc whose recording capacity is four times that of a disc in a magnetooptical disc system of the first generation. <IMAGE>

Patent DE-4418895-A1 (DE)
Title: Stirling machine
Inventor: NAKHMANSON RAOUL DR
IPC: F02G1/043
Filed: 1994-05-31
Abstract: Existing Stirling machines (engines and heat pumps) have a high efficiency, a low noise level, a wide range of fuels and continuous, i.e. complete and clean, combustion. Its disadvantage is its relatively high weight. In order to eliminate this disadvantage and also achieve a higher efficiency, a new Stirling machine has been constructed, as shown in Fig. 3. Here, 1 and 2 are the "QuadroRhomb" ("QR") positive-displacement machines in accordance with European Patent 0334302. These machines are lighter than currently employed designs with cylinders and pistons and furthermore have separate inlets and outlets. 5, 6 and 3, 4 act as inlet and outlet pipes for QR1 and QR2. A countercurrent heat exchanger 7 is inserted between the QuadroRhombs 1 and 2. This heat exchanger can, for example, be a thick tube through which there pass a large number of thin tubes with thin walls made of material of good thermal conductivity (e.g. copper). The gas flows passing through the countercurrent heat exchanger do not mix but merely exchange heat. The cold gas emerging from QR1 does not pass through a cooler, as in current practice, but is immediately heated in heat exchanger 7 and to a higher temperature in tube 6 and QR2. The hot gas coming from QR2 does not pass through a heater, as in current practice, but is cooled immediately in the heat exchanger 7 and to a lower temperature in tube 5 and QR1. This leads to an increase in the overall efficiency of the Stirling machine. QR1 and QR2 ... Original abstract incomplete. <IMAGE>
