Patent DE-19627142-A1 (DE)
Title: Grinder and cutter for metal
Inventor: HILKER ANDREAS
IPC: B24D7/18
Filed: 1996-07-05
Abstract: The grinder/cutter has tools, e.g. hard metal plates of automatically resetting material of limited deformability, arranged on tool carriers which can be deformed by operating integral piezoelectric elements. Thus the position of the tools can be changed to processing or non-processing position. One or more mutually independent tool carriers have tools mounted on them and can be interchanged with each other. Structures and reliefs can be removed from or introduced into the material depending on the program and based on the measurement values of the sensors.

Patent DE-19722760-A1 (DE)
Inventor: HOEVELING AXEL VON
IPC: B41C1/045
Filed: 1997-06-02
Abstract: The invention relates to a method for processing signals in an electronic graving machine for engraving printing forms. Engraving control signals (GS) for guiding the burin of a graving element are obtained from engraving data (GD) representing predetermined tone values between "light" (white) and "dark" (black). The burin engraves a series of cups in the printing form. The cup depths determine the tone values actually engraved. Before engraving, the engraving control signals (GSL; GST) corresponding to "light" and "dark" are calibrated by adjustment variables (EPL; EPT) so that the engraved "light" and "dark" tone values correspond to the predetermined "light" and "dark" tone values. So that the "light" engraved tone value remains constant when the "dark" tone value changes, the difference ( DELTA EPT) between the old "dark" adjustment variable (EPTalt) and a new "dark" adjustment variable (EPTneu) is formed before engraving. A new "light" adjustment variable (EPLneu) is then calculated on the basis of this difference ( DELTA EPT), and used to automatically recalibrate the engraving control signals (GSL) for "light", so that the "light" tone value remains constant.
Patent DE-19723953-A1 (DE)
Inventor: REITER FERDINAND
IPC: F02M61/16
Filed: 1997-06-06
Abstract: The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines, characterised in that the individual component parts are easy and economical to produce. The valve needle (18), which can be moved along the longitudinal valve axis (10), consists essentially of a thin wire (51). Said wire forms the extended downstream continuation of a spiral return spring (20). The valve needle (18) engages in a sealing element (52), said sealing element interacting with a valve seat body (23). Said valve seat body has a fixed valve seat. The valve needle (18) and the sealing element (52) are arranged in relation to the valve seat (23) in such a way that the wire transmits pressure forces onto the sealing element (52) and the valve seat (23) when the valve is in the closed position. The inventive fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compression, spark-ignition internal combustion engines.
Patent DE-19725656-A1 (DE)
Title: Assisting method for safe overtaking in road traffic for vehicle
Inventor: RAAV STEFAN
IPC: G08G1/16
Filed: 1997-06-18
Abstract: The method involves detecting a first distance and a first relative speed of the vehicle relative to an object to be overtaken.  A second distance and a second speed of the vehicle, relative to an object on the overtaking course, are also detected.  The method then involves calculating an overtaking route and/or an overtaking time of the vehicle, from the known first distance and the first relative speed. A first final distance between the vehicle and object on the course is calculated, from the second distance and second relative speed for the future instant when the vehicle is at the end of the overtaking path and/or when the overtaking time has elapsed.  The first final distance is compared with a predetermined value.  A warning signal is output when the first final distance is less than the predetermined value, or if the comparison is negative.
