    Patent number: 5784882
    Abstract: An exhaust manifold for conducting exhaust gas from an internal combustion engine including a collection pipe structure having branches with engine flanges at their ends for mounting to cylinder outlet ports of the engine and an outlet flange at the downstream end of the pipe structure for connection to an exhaust pipe. The collection pipe structure has in the area of the branches a cross-section with different diameters for first and second cross-sectional directions which are normal to each other so as to form a drop-like or oval cross-sectional area which, in a downstream direction, continuously changes until the two diameters are equal providing for a circular shape at the end of the collection pipe structure adjacent the outlet flange.

    Abstract: A layer construction with an organic layer and a transparent cover layer which covers the organic layer and which is harder than the organic layer, and a process for producing such a layer construction in which the cover layer is deposited on the surface of the organic layer from a precursor material present in the gas phase. In order to improve the optical quality of the layer construction, the cover layer, at least in a transition region between the organic layer and the cover layer, is deposited with an index of refraction which differs by a maximum of 20%, in particular by a maximum of 10%, from the index of refraction of the underlying organic layer.

  • Digital method for detecting pulses of short duration and arrangement for implementing the method
    Patent number: 5781591
    Abstract: A digital method for detecting pulses of short duration. During this process, a threshold value is formed using FIR filters with the assistance of a detection method similar to one in radar technology, by means of which threshold value short pulses to be detected can be distinguished from, in contrast, long pulses. The cut-off length of the pulses to be detected can be set in further ranges by way of simple parameter changes in the circuit. An arrangement for implementing the method is also disclosed.

  • Process for dynamically adjusting the power for a vehicle having a fuel cell
    Patent number: 5780981
    Abstract: The invention provides a process for dynamically adjusting the power of an electric driving unit of a vehicle which is supplied with electric energy by a fuel cell, the power of the fuel cell or the provided fuel cell current being controlled by means of the supplied air volume flow. The air volume flow is adjusted by the rotational speed of a compressor, a desired rotational speed value being predetermined for the compressor based on an accelerator pedal demand. Simultaneously, based on the measured air flow volume, the actually available fuel cell current is determined and therefrom a corrected accelerator pedal demand is determined. During the starting operation, the accelerator pedal demand is supplied directly to the driving unit, whereas, at higher rotational speeds, it is limited by the corrected accelerator pedal demand.

  • Process and apparatus for methanol reforming
    Patent number: 5772707
    Abstract: Process and apparatus for methanol reforming in producing hydrogen gas for electric vehicle fuel cells in which the gas mixture to be reformed is passed through a catalyst-containing reaction compartment. The active length and/or the active inlet cross-section of an intake-side reaction compartment section which is temperature-controlled for high methanol conversion can be set as a function of the throughput of gas mixture to be reformed. Thereby, an essentially constant residence period of the gas mixture to be reformed results in the reaction compartment section which is temperature-controlled for high methanol conversion. The methanol reforming may thus be carried out even in the case of markedly fluctuating throughputs of gas mixture to be reformed with a constant level of methanol conversion rate and constantly low formation of undesirable carbon monoxide.

  • Network for influencing signal fields
    Patent number: 5771319
    Abstract: The invention relates to analog circuits which are constructed as fed-back amplifier networks. The networking is implemented such that the output values of the individual amplifier elements are fed back to the input values of the respective adjacent amplifier elements. The degree of feedback can be statically and dynamically adjusted according to the specific application. Two-dimensional networks with such an architecture can be used, for example, in image processing for the interference reduction under real-time conditions.

  • Process for cooling engine walls and wall structure for carrying out the process
    Patent number: 5765360
    Abstract: Cooling of engine walls with fuel, wherein the walls have a structure which has an inner wall, to which hot gas is admitted during the operation, a colder outer wall, as well as a plurality of webs which connect the walls and divide the hollow space present there into a plurality of cooling ducts.The fuel is introduced in the cold state into the wall structure, is delivered through the cooling ducts while absorbing heat via the inner wall, and is subsequently used to generate thrust.A hot fluid flow taken from the engine is admitted during the operation from the outside to the "cold" outer wall of the wall structure, through which fuel flows, and this "cold" outer wall thermally expands as a result, or its thermal contraction is reduced.

  • Method and system for metered supply of methanol and/or water to a fuel-cell system
    Patent number: 5766786
    Abstract: A method and a system meters a supply of methanol and/or water out of a storage reservoir to a fuel-cell system by way of a conveying conduit with a metering valve. A constant mass flow is conveyed out of the storage reservoir into the conveying conduit via a conveying pump. The differential pressure between the conveying conduit and fuel-cell system is set at a predetermined value via a differential-pressure controller which is arranged in a return conduit provided between the conveying conduit and storage reservoir. The methanol and/or water supplied can be set, for example, by varying the opening and closing times of a solenoid valve. A second metering stage can be provided in the return conduit downstream of the first metering stage. When two separate metering systems are used, a common pump motor can be employed.
