Abstract: A device (12) supplies energy to a rapid cycling and/or rapidly cycled integrated circuit (13, 52) which includes a circuit load (17) and an internal capacity (15) connected parallel to the circuit load (17). The integrated circuit (13, 52) has a high cycle frequency (f1) especially at least in the MHz range. A supply unit (14) especially designed as a current source is directly connected to the internal capacity (15). The supply unit (14) has an internal resistance, the impedance level of which is so high at the cycle frequency (f1) that a current (ID2) supplying the circuit load (17) originates to a greater degree from the internal capacity (15) than from the supply unit (14). At least one auxiliary load, current sink or load controller is provided as an integral component of the integrated circuit and is connected to the circuit load to smooth load fluctuations.

Abstract: A floor care machine such as a floor polisher includes a machine frame carrying a motor coupled through a drive arrangement to a rotationally driven head on which a floor care disc such as a polishing pad is mounted. The drive arrangement includes a drive element rotationally driven by the motor, and a driven element that is connected to the driven head and is automatically height adjustable. The drive element includes a bearing hub, an outer ring and four uniformly rotationally offset spokes that carry first rolling guides extending along helical paths about the rotation axis. The driven element includes upper and lower partial elements that receive the spokes therebetween and carry second rolling guides arranged facing the first rolling guides along the helical paths, and roller bodies are interposed therebetween. Relative rotation between the drive element and the driven element causes an axial height adjustment of the driven head.

Abstract: For a motor vehicle control device, a housing lid and a base plate form a hollow area that contains an interconnect device arranged on the inner side of the housing lid. The housing lid has at least one opening surrounding the interconnect device, adjacent to an electronic component and/or an electrical contact area on the interconnect device. On or in the opening, a flexible foil conductor strip is arranged with an end section thereof covering the opening. A lid plate covers the opening completely, and the interposed foil conductor strip is thus connected in an oil-tight manner with the housing lid. Electrical connection lines between the components and/or the contact areas on the interconnect device and an electrical contact area on the end section of the foil conductor strip create the electrical connection between the control electronics on the interconnect device and the surrounding area outside of the control device.

Abstract: An upper structure for a shoe improves a fit of the heel portion during heel contact with the ground to the push off motion of a foot. The upper structure includes an upper body 30, and an outside upper member 31 that overlaps the lateral side of the upper body 30 to cover the talus T of the foot, and that has a bottom edge portion 31a fixedly attached to the bottom surface of the upper body 30. The rear end portion A of the bottom edge portion 31a is located rearwardly of the load centerline C of the calcaneus. A rear edge portion 31c of the outside upper member 31 is provided separately from the upper body 30 rearwardly of the talus T of the foot. An instep edge portion 31b of the outside upper member 31 is connected to the shoelace 4. On the lateral side of the heel portion of the upper body 30, there is a region 10 that is expandable and contractible in the longitudinal direction.

Abstract: A tank arrangement includes a tank for storing a liquid such as fuel or oxidizer for operation of a spacecraft and a pressurized driving gas for conveying the liquid out of the tank, and a gas supply and extraction device. The device includes a housing shell and plural outwardly expanding passage bodies providing openings that communicate the interior space of the tank to the inner reservoir space of the device. A baffle plate shields the outer opening of each passage body. Deflector plates are arranged in each passage body. Capillary plates extend longitudinally along the inner wall of the housing shell. By a capillary effect, the plates separate liquid from gas entering the device, so that the gas can be extracted while the liquid is stored in a reservoir of the device until it is drained back into the tank during an accelerated operation phase of the spacecraft.
