| 20090278019 | MACHINE HAVING A MACHINE ELEMENT THAT CAN BE MOVED ALONG A CROSSBEAM - The invention relates to a machine provided with a machine element ( | 11-12-2009 |
| 20090309454 | PIEZOELECTRIC ACTUATOR - A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus. | 12-17-2009 |
| 20090310752 | Control method for guided movement of an x-ray examination system - According to the invention, an X-ray examination may be simply and rapidly carried out and hence produce a sharp X-ray image with an X-ray source ( | 12-17-2009 |
| 20100032879 | MACHINE TOOL - The invention relates to a machine tool, wherein the machine tool has a workpiece clamping device ( | 02-11-2010 |
| 20100052450 | DRIVE ARRANGEMENT FOR MOLDING MACHINES AND EXTRUDER HAVING TWO DRIVES - A drive arrangement with a first motor and a second motor is described, the first and second motor being coupled via a first coupling unit. The first motor is provided to generate uniform low-frequency movements and the second motor performs a higher frequency alternating movement to be overlapped. The total movement is transmitted from the second motor to a machine component coupled via a second coupling unit. The first coupling unit is configured to transfer the uniform low-frequency movement of the first motor to the second motor, wherein a transmission of the higher frequency alternating movement of the second motor to the first motor is suppressed. | 03-04-2010 |
| 20100092262 | MACHINE TOOL, AND METHOD FOR THE DAMPING OF OSCILLATORY MOVEMENTS OF A MACHINE ELEMENT OF A MACHINE TOOL - A machine tool includes a first motor, a gear, and a machine element which is movable in a direction of movement by the first motor via the gear. A second motor is provided to apply a force directly upon the machine element in the direction of movement of the machine element in the absence of an interposed gear between the second motor and the machine element. The second motor is constructed to operate in such a way that the applied force counteracts an oscillatory movement of the machine element in the direction of movement of the machine element. | 04-15-2010 |
| 20100247261 | METHOD FOR REDUCING VIBRATIONS, WHICH OCCUR DURING A MACHINING PROCESS, OF A MACHINE ELEMENT AND/OR OF A WORKPIECE - The invention relates to a method of reducing vibrations, occurring during a machining operation, of a machine element ( | 09-30-2010 |
| 20110234125 | ARRANGEMENT FOR SUPPLYING POWER TO A COUPLED SYSTEM OF MACHINES - An arrangement for supplying power to a system includes a first electric drive unit constructed to supply mechanical power to or receive mechanical power from a first coupled system of machines and a second electric drive unit constructed to supply mechanical power to or receive mechanical power from a second coupled system of machines. The first and second coupled system of machines are constructed to receive mechanical power or mechanical energy or to supply mechanical power or mechanical energy. The arrangement further includes a first kinetic energy storage device having a first electrical energy exchange machine which is electrically connected to the first electric drive unit, and a second kinetic energy storage device having a second electrical energy exchange machine which is electrically connected to the second electric drive unit. The first kinetic energy storage device is coupled to the second kinetic energy storage device. | 09-29-2011 |
