Patent DE-19626223-A1 (DE)
Title: Kelly string with latching assemblies
Inventor: LOESER GOTTFRIED
IPC: E21B17/07
Filed: 1996-06-29
Abstract: The kelly string unit for drilling boreholes includes hollow telescopic rods (10, 11, 12) with latches (20, 30). The latter lock the sections of the Kelly string together, when they are extended. In novel design, the latches (20, 30) are moved out radially from the rods (10, 11), by a control section (32, 22) which can be moved axially along the rod. Each successive inner rod (12, 11), is so constructed, that it moves the control section (32, 22) into a latch-releasing position, when the rods are telescoped together.

Patent DE-19630656-A1 (DE)
Inventor: JONES GARETH MARK
IPC: F16F9/43
Filed: 1996-07-29
Abstract: A damper 10 is filled with pressurized gas by forming a flow passage 96 between the dust lip 66 of the oil seal 50 and the piston rod 14. The flow passage 96 is formed by locally deforming the dust lip under the action of the jaw members 88 of a distortion clamp 86. A source of pressurized gas is then placed in communication with the flow passage, the pressure causing the oil seal to be displaced away from the piston rod, the gas entering the damper between the oil seal and the piston rod. When the gas within the damper has attained the desired pressure, the distortion clamp is released allowing the dust lip to return to normal circumferential contact with the piston rod, and the source of pressurized gas is removed.

Title: Document or picture reading device
Inventor: YAMAKAWA SHINJI
IPC: H04N1/053
Filed: 1997-01-24
Abstract: The reference pattern has oblique lines provided outside the read zone and they are read by separate picture sensors. A sensor detects an edge of one of the oblique lines, to provide a reference position for the picture data. Two delay units have a number of line memories for picture data from the original picture. The two units determine picture data and place image data in each of the colour values as imaginary points, using interpolation. A selector unit chooses one of the imaginary points with picture data having the minimum difference in colour values. The positions of the picture elements are now corrected, using interpolation and correction factors. The image is then printed. The process is directed by the system control (4).

Title: Automatic image recognition technique for comparison of tissue structures and cells, especially in medical diagnosis
Inventor: VORBRUEGGEN JAN DR
IPC: G06K9/64
Filed: 1997-06-22
Abstract: This automatic recognition technique detects structures in biological sections, especially for medical diagnosis. In the new method, reference graphs formed by digitisation of sectional images each comprise a net structure defined by allocation of nodes to specific image data, which are interconnected by links in predetermined manner. Each node is also allocated a jet (mathematical concept). This is evaluated with the image data of the corresponding reference section at the defined nodes, through convolution of a class of filter functions of diverse magnitude and orientation. The image of the section including each of the structures to be recognised, is digitised. Now an optimal sectional graph is evaluated for each reference graph, on the basis of optimal fit.

Patent DE-19749389-A1 (DE)
Inventor: HAARDT MARTIN DR ING
IPC: H04B7/26
Filed: 1997-11-07
Abstract: In a data transmission process between radio stations in a radio communication system, first signalling data are superimposed on additional data at the transmitter side to form a sum signal. The data are transmitted simultaneously. The sum signal is then transmitted in a frequency channel and the different data can be distinguished on the basis of individual fine structures. A reception signal is evaluated at the receptor side and any influence of the first signalling data on the additional data is removed by an equalising calculation. Finally, the additional data are detected. The process can be used in particular with TD/CDMA transmission processes.
