Patent DE-4316759-A1 (DE)
Title: Directional valve with a proportional function
Inventor: NIKOLAUS HEINRICH WOLFGANG PRO
IPC: G05D7/06
Filed: 1993-05-19
Abstract: The invention relates to a digital controller structure with whose aid standard directional valves having pulse magnets can be used as proportional valves. By means of suitable dimensioning of the correction factors used in the control loop, in the case of a defined desired value preset by the electronics, the flow in the directional valve can be kept constant over large pressure ranges, that is to say this arrangement corresponds to a proportional valve with an integrated pressure balance.

Title: Method for operating a compression-ignition internal combustion engine
Inventor: FRAENKLE GERHARD DR ING
IPC: F02B21/00
Filed: 1993-05-21
Abstract: In a method for operating a compression-ignition internal combustion engine with a combustion chamber and an accumulator which is connected to the combustion chamber by way of an opening which can be closed by a control valve, air which is forced into the accumulator during the compression stroke is used to modify the compression ratio. To improve the utilisation of the air enclosed in the accumulator, this air is blown into the combustion chamber during the power stroke by opening the control valve and increases the turbulence in the combustion chamber towards the end of combustion. As a control valve use can be made of an additional throttle valve used in the braking mode of the internal combustion engine.

Title: Set arrangement for the switched feeding of an electromagnetic load
Inventor: VOGEL WOLFGANG DIPL ING
IPC: G05D16/20
Filed: 1993-09-04
Abstract: In this load, a regulator unit is provided by means of which a pulse-width-modulated control signal is formed in dependence on the difference between an instantaneous-value signal (actual value) at the load and a predeterminable guide signal (nominal value). This pulse-width-modulated control signal is used for driving a power switch by means of which an electric current is applied to the electromagnetic load. The core of the invention is the design of a detection device for detecting an instantaneous quantity present at the power switch, which, for example, represents the electric current present at the electromagnetic load. For this purpose, the detection device is designed in such a manner that it detects the instantaneous quantity present at the power switch in dependence on the pulse-width-modulated control signal. <IMAGE>

Title: Fitted-together covering lid and its attachment on food containers
Inventor: ZIMMERMANN JOHANN DIPL ING
IPC: B65D43/10
Filed: 1994-05-20
Abstract: The fitted-together covering lid and its attachment on food containers serves to close vessels with the aid of the negative pressure in the vessel (3), said negative pressure being produced by the covering lid consisting of a lid (1) and the label (2). When the pressure increases in the vessel (3), the lid (1) returns, together with the label connected to it, into its starting position before the negative pressure is produced in the vessel and indicates that opening has taken place or the pressure has changed due to non-tightness of the package or due to perishing of the food contained in the package. Furthermore, the lid (1) and the label (2) are designed and fitted together in such a way that they support each other and thus allow less material to be used. The design of the lid (1) and label (2) allows the exchange of gases which can be determined beforehand through the fitted-together covering lid from the vessel side to the outside and vice versa. <IMAGE>

Title: Measuring system for measuring level of liquid or flowable media in container
Inventor: KUEBLER HEINRICH DR
IPC: G01F23/76
Filed: 1994-08-04
Abstract: The level measuring system includes two float units (12.1,12.2) each containing a magnet and movable along slide pipes (18.1,18.2). At least one float can change in relation to its specific wt., by having a screw cap (20) for the addition or removal of a ballast material e.g. sand. This enables the determination of different levels of media having different specific weights. Each slide pipe contains a series of chips along its length, each containing a reed switch activated by the float magnet, and a resistor. An evaluation unit determines the level from the resistances along the slide pipes. An indicating unit is connected to the evaluation unit and converts the signal of the evaluation unit into optically readable information which is then indicated.

Title: Contactless detection of motion
Inventor: PROBST GREGOR DIPL ING
IPC: G01P3/42
Filed: 1994-08-10
Abstract: A pulsed light beam (8) is directed towards a measurement position (7) at which markings (5) of defined lengths on the machine part (2) pass by successively in the direction of motion (1). The light reflected from the markings is detected and evaluated. The light beam is focused so that it produces a light spot (9) when incident upon the markings.  The light beam is pulsed at a defined frequency and the light spots produced at each individual marking, and detected when reflected from it, are counted.

Patent DE-4443169-A1 (DE)
Title: Valve with variable electronic control for high-speed heat engine
Inventor: DENS JUERGEN DIPL ING
IPC: F01L9/14
Filed: 1994-12-05
Abstract: Delayed closure of the valve (6) is effected by electroviscous liq. pumped through an inlet (1) into the working space (2) of a cylinder (9) in which a cup-shaped piston (4) is driven by the rotation of a cam (5), against the opposition of a return spring (8).When no voltage is applied to the annular electrode (7) in the cylinder head, the liq. flows straight through an outlet (3) to a cooler for recirculation. At max. valve opening, a voltage on the electrode increases the viscosity of the liq. so that the valve is held open independently of the cam until the desired closure time, whereupon the voltage is removed.
