Abstract:
The invention relates to a base or a mounting frame for an electrical enclosure or a rack, comprising mounting pieces which are arranged, as corner pieces, in the corner regions of a rectangle or square that extends in an x-y plane, said mounting pieces being produced in a respective shaping process and comprising first and second mounting faces which lie outside with respect to the rectangle or square, which extend in the x direction and in the y direction at a right angle thereto and which extend in a space direction z at a right angle to the x-y plane, wherein sections of a system of covers are brought into contact with the mounting faces, said covers having lateral covers with cover walls that are flat on the exterior and that have reinforcing ribs extending longitudinally on the interior, and being fastened to receiving structures of the mounting pieces by connecting means. Benefits in the installation process are achieved in that the lateral covers have cover fastening elements formed onto the interior of the lateral covers and are fastened directly or indirectly to the receiving structures of the mounting pieces by means of said cover fastening elements.
Abstract:
A method for assembling motor vehicles, in particular personal motor vehicles having a self-supporting shell involves equipping the respective shell of the motor vehicle with a corresponding chassis and equipping the chassis with vehicle wheels at least before an end of a main assembly line has been reached.
Abstract:
A method for tracking a surface representation includes providing an initial mesh representing a surface, the initial mesh comprising a plurality of mesh faces. A grid is constructed, the grid having a plurality of grid edges, whereby each grid edge is connected between two grid nodes, and each grid node has a predefined value associated therewith. The grid overlaps the initial mesh, such that at least one mesh face intersects at least one grid edge. A new value for a grid node connected to the intersected grid edge is computed based upon its intersection by the mesh face, and the initial mesh is modified based upon the new value of the grid node to produce a modified mesh, the modified mesh providing an updated representation of the surface.
Abstract:
The invention relates to a method for controlling a hydrostatic drive having at least one first hydraulic consumer and one second hydraulic consumer. The two hydraulic consumers are driven by a common drive machine. First of all, a first power requirement of the first hydraulic consumer is determined (20). Proceeding from the determined first power requirement, the free power which is available as a result of the common drive machine is determined (21). This available free power of the common drive machine is scaled onto a possible actuating path of a control transmitter for the working hydraulics (22). A position of the control transmitter for actuating the second hydraulic consumer is determined (23) and a power requirement is assigned on the basis of the scaled available free power. An operating point of the common drive machine is fixed from the first power requirement and the second power requirement (24).
Abstract:
A method for detecting cavitation in a hydrostatic system includes capturing an oscillation typical for the cavitation from a pressure captured over time. Furthermore, the method includes establishing an evaluation variable for cavitation on the basis of the captured oscillation. Additionally, the method includes comparing the evaluation variable to a comparison value.

Abstract:
A hydrostatic fan drive for internal combustion engines is disclosed, having a primary unit that can be driven by the internal combustion engine, and having a fan motor by means of which a blower fan can be driven. A hydraulic reservoir is disposed at a high-pressure line connecting the primary unit to the fan motor. A hybrid fan drive for internal combustion engines is thus provided, allowing fan operation even if the internal combustion engine is switched off. An increased maximal available power of the internal combustion engine is available in transition, despite the fan operation, because the fan motor can be supplied with pressurized media by the hydraulic reservoir in such cases (in transition).
Abstract:
A method of controlling a hydrostatic drive is provided. The hydrostatic drive has a hydraulic pump and a hydraulic engine. The hydrostatic drive further has a first and a second hydraulic reservoir for storing and recuperating energy. Pressure energy is stored in the first reservoir. For the purpose of recuperating the pressure energy stored in the first reservoir, the first reservoir is connected to a suction side of the hydraulic pump. A downstream working line of the hydraulic engine is connected to the second reservoir. In addition, the downstream working-line connection of the hydraulic engine is disconnected from the suction side of the hydraulic pump.

Abstract:
The present invention relates to the use of a GPR4 inhibitor for the manufacture of a medicament for the inhibition of angiogenesis, for instance for the inhibition of tumour growth in the treatment of cancer. In a preferred embodiment, said inhibitor is a siRNA, preferably double-stranded.In addition, the present invention further encompasses non-human animals wherein the GPR4 has been inactivated, for instance a knock-out mouse lacking GPR4, and the use of said animals as an experimental model for angiogenesis and for screening for compounds modulating angiogenesis.
