Patent DE-19649628-A1 (DE)
Title: Mineral seal construction, manufacturing processes and geosynthetic sealing strip
Inventor: HEERTEN GEORG DR ING
IPC: E02D31/00
Filed: 1996-12-01
Abstract: A mineral seal construction, especially for sealing waste tips, stagnant industrial land or similar areas, includes two or more clay layers(2a,2b) separated from each other by intermediate layers(4) which ensure that the water content in each clay layer is independently controlled in both wet and dry conditions to maintain the clay in a soft, effective sealing condition. An alternative construction comprises at least one clay layer(2) and water storage layers(5) above and/or below it which ensure that the water content of the clay layer remains constant and gives a soft clay consistency for effective sealing. A claimed water and/or oil permeable, geosynthetic clay sealing strip comprises a carrier(1) and a cover(3) layer a swellable clay layer between them and the outer layers(1,3) are connected so that during swelling they remain together and transfer shear force from the cover into the carrier layer. The clay layer may comprise two clay layers(2a,2b) or two fleece and /or open cell foam layers containing clay separated by an anti-capillary layer(4). A process for continuous manufacture of the geosynthetic clay sealing strip involves covering a carrier layer(1) with powdered and/or granulated swellable clay(2a), covering with an anti-capillary layer(4), applying a further layer of clay(2b) and an outer cover layer(3). All layers(1,2a,4,2b,3) are then needled, sewn, knitted or welded together. An alternative geosynthetic clay sealing strip comprises a carrier and a cover layer with a swellable clay layer between swellable clay between them. One or more water storage layers are located above and below the clay layer, above, in or under the cover layer and/or under, in or above the carrier layer and all layers are connected together to retain integrity during swelling and transfer shear stress. In a process for manufacturing this alternative geosynthetic sealing strip a water storage layer is placed on a carrier layer, followed by a swellable clay layer, a second water storage layer and finally a cover layer. All layers are then connected as described. In a variation of this process a first water storage layer is placed on the carrier, followed by two layers of powdered or granular clay separated by an anti-capillary preventing layer, a further water storage layer and cover layer.

Patent DE-19722761-A1 (DE)
Inventor: WEIDLICH ERNST-RUDOLF GOTTFRIE
IPC: H04N1/409
Filed: 1997-06-02
Abstract: The invention relates to a method for correcting the sharpness of image values. According to the inventive method, the image values are presented in an original range of values, said image values being produced pixel by pixel. The image signals presented in the original range of values are compressed into an intermediate range of values before the sharpness is corrected. Said intermediate range of values is measured in such a way that the signal exaggerations produced when the sharpness of the compressed image values is corrected fall within the original range of values. The sharpness of the image values is then corrected as follows: surround field values are obtained for the individual pixels by means of evaluating each of the surround fields of said individual pixels, difference values are produced from the image values and surround field values and said image values are then overlaid with difference values of a chosen strength, said difference values serving as a signal for correcting sharpness. The image values with corrected sharpness are then decompressed to the original range of values.

Title: Frequency synchronisation method for oscillator
Inventor: WEINHOLD MICHAEL DR ING
IPC: H03L7/085
Filed: 1997-07-17
Abstract: The method involves synchronising the frequency of an oscillator on a measured, periodical system value. A complex Fourier coefficient is determined for each basic oscillation period of a Fourier series of the system value for its basic oscillation frequency.  A phase value of the complex Fourier coefficient is calculated, and a phase difference value is determined from two timewise consecutive phase values. A correction pulse period,which is added to a nominal pulse period, is determined from the phase difference value, in such way that the phase difference value becomes zero.
