Abstract: A sole structure for a sports shoe includes a wavy corrugated plate that is disposed at a heel region of the sole structure and that has corrugations around the heel circumferential portion. The amplitude or height of each corrugation becomes gradually greater toward the heel circumferential edge. The sole structure further includes pillar members formed of rubber and disposed around the heel circumferential portion on the bottom surface of the wavy corrugated plate. The top surfaces of the pillar members include inclined surfaces that slope downwardly as they progress outwardly from the heel central portion toward the heel circumferential edge.

Abstract: In a frequency-modulated radar system and method for detecting the surroundings, a compensation of interfering effects is achieved by varying one of the following values: a) a time spacing or temporal distance between the transmitted frequency ramps or the time gap between the frequency ramps, b) a time from the start of the respective transmitted frequency ramp to the beginning of the scanning of the received signal, c) a frequency at the start of the transmitted frequency ramp, and d) a sign of the slope of the transmitted frequency ramps.

Abstract: The invention relates to a method for controlling the operating mode of an internal combustion engine (1) comprising several cylinders (3) and an injection system (4) with one injection unit (5) per cylinder (3). According to said method: a digital measuring signal, which characterizes the combustion of fuel (6) in the internal combustion engine (1), is first determined; said digital measuring signal is then transformed into a frequency range; a misfiring of the ignition is detected using the amplitude information of the transformed measuring signal and if a misfiring has occurred, the injection of the individual cylinders (3) is deactivated sequentially for a predefined period and for each cylinder the corresponding digital measuring signal that characterizes said cylinder is determined and transformed into the frequency range and a misfiring cylinder (3) is identified during the evaluation of the transformed measuring signal using the amplitude information.

Abstract: An apparatus for producing a molded product from a sheet-form raw material blank has first and second mold tools that each respectively include a respective inner core mold and a respective outer edge mold laterally adjacent thereto. Drive elements drive the outer edge molds relative to a machine frame, and drive the inner core molds relative to the outer edge molds. A molding process involves closing the outer edge molds to hold an edge rim of the material blank while allowing slippage thereof, and then closing the inner core molds to three-dimensionally deform and mold a central portion of the material blank while pulling required additional material by slippage through the outer edge molds. A separate slip frame is not used. The edge rim held by the outer edge molds remains as a permanent mounting rim or flange of the finished molded product. Edge waste is minimized.

Abstract: In a method of repairing a structural component, especially a stator-side structural component such as a housing or a guide vane ring of a gas turbine, a damaged section is separated-out along a separating line and removed from the structural component, and a new section that replaces the removed damaged section is connected with the structural component by welding along the separating line to produce a weld seam. The damaged section is separated-out from the structural component so as to minimize the length of the separating line and thus the weld seam. Depending on the material thickness distribution of the component along the separating line, material is removed from the structural component to provide the most uniform possible material thickness along the weld seam. After connecting the new section with the structural component by welding, at least the removed material is renewed by laser powder deposit welding.

Abstract: A processing area of a structural component, such as a gas turbine component, is heated by irradiation with several laser sources prior to and/or during and/or after carrying out a processing such as a deposit welding or machining of the component on the processing area. For the heating, each laser source directs a respective energy beam onto the processing area, which respectively produces an energy spot on the processing area. The respective positions of the energy spots are static or quasi-static on the processing area. The energy spots jointly heat the processing area.
