Patent number: 7871070Abstract: A conveyor conveys sheets and deposits the sheets at a location to be stacked. The conveyor includes a sensor for determining the presence of a sheet before the sheet arrives at the location. A controller is coupled to the sensor and responsive to sensor inputs for controlling a movable support for projecting into a projected orientation to receive the sheets as the sheets exit the conveyor. The movable support moves to a retracted orientation to assist a stack to be withdrawn therefrom.Type: GrantFiled: March 9, 2005Date of Patent: January 18, 2011Assignee: Padana AGInventors: Arlington D. Ruff, Clifford A. Ruff, Jürgen F. Trost

Patent number: 4245869Abstract: An electromagnetic bearing system for a movable (usually rotatable) member on a stationary member has bearing coils wound on a core for producing a magnetic field for supporting the movable member. High frequency sensor currents are applied to the bearing coils or to separate sensor coils on the same core or core portion as the bearing coils. The sensor currents produce signals responsive to deviation of the movable member from a desired position in which it is to be supported. These signals are amplified to provide bearing currents which are fed to the bearing coils.Type: GrantFiled: August 7, 1978Date of Patent: January 20, 1981Assignee: Padana AGInventors: Dietrich Scheffer, Rolf Guse

Patent number: 4080012Abstract: A contactless magnetic bearing system comprises a passive axial bearing element which serves to exert axial stabilizing forces on the rotor and at the same time exerts radial destablizing forces thereon, a controlled or active radial bearing element for counteracting these radial destabilizing forces and a passive radial bearing element which supports and journals the rotor at a position axially spaced from the two first-mentioned bearing elements. The axial destabilizing forces produced by the passive radial bearing are counteracted by the much stronger axial forces exerted by the passive axial bearing element.Type: GrantFiled: April 29, 1975Date of Patent: March 21, 1978Assignee: Padana AGInventors: Karl Boden, Werner Geweke

Patent number: 4037886Abstract: A contactless magnetic bearing between two members, not necessarily relatively rotatable, comprises at least one magnet on one member cooperating with two ferromagnetic parts on the other member to exert a stabilizing effect in the direction of one degree of freedom due to oppositely directed mgnetic fluxes in the two parts parallel to the direction of the degree of freedom. The destabilizing effect in a direction transverse to the direction of the one degree of freedom can be countered by a lateral bearing, preferably an active bearing whose coil is arranged in the magnetic field of the magnet or magnets.Type: GrantFiled: April 29, 1975Date of Patent: July 26, 1977Assignee: Padana AGInventors: Karl Boden, Werner Geweke
