20140050425 | INTEGRAL METHOD FOR VIBRATION COMPENSATION AND MISALIGNMENT PREVENTION IN ROTOR DYNAMIC SYSTEMS - A method for suppressing vibrations, the method having the steps of providing a first device having a first rotating shaft, and a second device having a second rotating shaft. The orbits of the first rotating shaft are measured are analyzed, and the misalignment and unbalance is determined. The first rotating shaft and the bearings are then displaced to eliminate vibrations. | 02-20-2014 |

20130076467 | GUIDE HAVING PASSIVE GRAVITY COMPENSATION AND A VERTICALLY MOVABLY MOUNTED PLATFORM - A guide having passive gravity compensation via a magnet assembly for guiding a first body relative to a second body in a vertical direction has a spring guide which allows movements between a first and second body in the vertical direction and blocks the same in all other directions. The first body is connected to a first magnet and the second body to a second magnet. The second magnet has an opening within which the first magnet is configured, at least in part, so that a repulsion force, which counteracts the gravity of the first body, acts between the first and the second magnet that are each magnetized parallel to the vertical direction, but oppositely, the positive mechanical stiffness of the spring guide being at least partially compensated by a negative stiffness of the magnetic spring formed by the first and second magnets, and the first and second magnets being shaped such that a horizontal distance between the first and second magnet inside of the opening of the second magnet varies in the vertical direction. A platform supported by such guides is provided. | 03-28-2013 |

20150378266 | XY-TABLE - An XY-table includes a separate drive for reversing the direction of movement of the table. A ferromagnetic rib projects at one edge of the table and extends perpendicular to the direction of movement of the table to be reversed. The drive has a magnetic yoke for receiving the rib when the table is near a reversal point, the free ends of the magnetic yoke having pole shoes which concentrate a magnetic flux in the yoke, switchable with the aid of a reversal coil, in an air gap through which the rib extends into the interior of the yoke. | 12-31-2015 |
20150381023 | DRIVE FOR AN XY-TABLE AND XY-TABLE - A drive for an XY-table includes a stationary, ferromagnetic and U-shaped yoke including a first limb and a second limb which are located together in one plane, and having a movable ferromagnetic bar, the yoke and the bar carrying a magnetic circuit with a flux that takes a path across air gaps between the limbs and the bar, and causes vertical reluctance forces there which counteract the gravitational force of the bar. Bar is parallel to and below the plane defined by the limbs. | 12-31-2015 |
