Patent DE-19627626-A1 (DE)
Title: Dewatering process for brown coal for use in a power station boiler
Inventor: STRAUSS KARL PROF DR
IPC: F01K17/06
Filed: 1996-07-09
Abstract: In a process to reduce its water content, a bed of granulated brown coal (22) is subjected to a surface pressure below the maximum pressure used in the process, and is heated by condensing steam. The steam flow is then turned off, and the pressure is raised to a surface pressure of at least 20 MPa, and high enough to express water from the coal. The expressed water is used to preheat incoming brown coal prior to the first stage of the process. The steam used is obtained as a side stream of the steam fed to a power station turbine (1), and is fed either to the brown coal (22) or to a vessel containing expressed water to heat it further.

Patent DE-19652951-A1 (DE)
Inventor: MAHLER GEROLD DR
IPC: B27K5/00
Filed: 1996-12-19
Abstract: The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of mushrooms, bacteria and wood cells that are still alive, thereby forming CO2 and H2O. Fermentation processes also lead to the decomposition of hemicelluloses and saccharides which are converted to organic acids and CO2. The oxygen content in the cover is less than 0.1 vol. % after an adjustment time of 3 to 10 days of total stocking, while said CO2 content rises to more than 21 to 40 vol. % . This method enables green round wood and sawn timber to be stocked over long periods without wastage or environmental damage.

Patent DE-19654358-A1 (DE)
Title: Interior illumination for vehicle
IPC: F21V8/00
Filed: 1996-12-24
Abstract: The point-source lamps e.g. filament bulbs, LEDs etc. project light into one end of the light guide (5). The output face of the light guide has a larger area then the input face and a light diffusing cover (15) to further even out the light intensity to a comfortable background level. The back face of the light guide, opposite to the output face, has a light scattering surface to direct light to the output face. The degree of light scattering of the back face of the light guide increases away from the input face, to compensate for the reducing light intensity away from the input face. This provides an even light output over the output face. The rear face of the light guide has a surface texture of grooves and ridges with the texture pattern varying away from the input face.

Patent DE-19733221-A1 (DE)
Inventor: MUELLER WOLFGANG
IPC: H02P9/30
Filed: 1997-08-01
Abstract: The invention concerns a method for regulating a generator, whereby the rectified output voltage supplied by a generator is converted, in predetermined conditions, by means of a direct voltage converter. Said generator can operate in free mode or in regulated mode. If the generator voltage supplied in each mode does not correspond to the on-board power system, the generator voltage is increased or decreased by means of a voltage converter. The operating mode is selected on the basis of the rotation speed or the voltage, such that the available generator power or the energy conversion efficiency is the highest possible.

Patent DE-19804327-A1 (DE)
Title: Method for exact rpm determination of IC engine
Inventor: OTT KARL
IPC: G01M15/11
Filed: 1998-02-04
Abstract: The method involves using an eccentric transmitter disc attached to the crankshaft, and measuring the eccentricity to provide compensation factors to obtain exact rpm. An eccentric transmitter disc (1) rotating with the crankshaft has a number of approximately equidistant markings (2), which are scanned by a sensor (3). After an identification step, a detection step is carried out from a reference time, to detect the beginning or end of each marking through the evaluation of the sensor signal. A compensation step provides dynamic compensation of each single marking time point for a rotation of the shaft, and forms a compensation factor for each marking time. An average value is formed from all the factors compensation factors. A first extraction step determines the maximum eccentricity error by extracting the compensation factors that correspond exactly to the average value. A second extraction step extracts, which is not for correcting marking lines which have no deviation, caused by the disc eccentricity, involves halving a time interval or angular distance between the factors extracted in the first extraction step. A correction step corrects the deviating time points to obtain the exact rpm.
