  • Publication number: 20020057957
    Abstract: A method for loading an aircraft (R) with shipping containers (3), the latter being passed on conveyor members (13) into the interior of the aircraft (R) and rotated there in a loading area (8), the position of the shipping container (3) in the loading area (8) is determined and the conveyor members (13) are operated via a control system in accordance with the determined position to rotate the shipping container (3).

  • Patent number: 6279730
    Abstract: An arrangement for conveying material to be conveyed along a conveying plane, in particular for freight-loading systems in freight compartments, preferably of aircraft is disclosed. The arrangement provides that driving material to be conveyed along a conveying plane, with which safe, reliable transport of the material to be conveyed is ensured with low wear of the conveying roller under widely varying operating conditions. This is achieved in that, in a drive unit, the conveying roller is connected to a first drive and an associated first activating unit for producing a requisite traction force for moving the material to be conveyed along the conveying plane.

  • Patent number: 6218829
    Abstract: A device for registering the displacement travel and/or the displaced position of a sliding component, which is moved free of torsion, of a linear drive is intended to be implemented on a small scale and with display precision. For this purpose, the device is equipped with at least two magneto-resistive sensors which act within a separate magnetic field, respectively assigned to the displacement component in different regions located one behind the other.

  • Patent number: 6189391
    Abstract: A linear drive having a device for sensing and evaluating an operational force acting on the linear drive is to be of simple design and is to be constructed so as to be functionally effective with a high degree of accuracy. For this purpose, the operational force on the bearing part supporting the displaceable part of the linear drive in a housing is sensed and electronically evaluated by a magnetostrictive force sensor.

  • Patent number: 5791191
    Abstract: In a gear which can be flanged onto an electric motor, especially a low-clearance planetary gear, with a hollow shaft to make a positive connection with the electric motor output shaft, an easily manufactured and reliable centering system is to be provided between the gear and the electric motor (6). To this end, the section of the hollow shaft (9) accepting the output shaft (10) of the electric motor is centrically secured on roller bearings (11) and the face of the drive flange is radially freely centerable (7, 8) in relation to the mating surface of the electric motor. To enable a drive with as uniform a basic structure as possible to be connected to electric motors with different connecting geometries, the gear has an interchangeable mating plate (2) forming its connecting flange and a hollow shaft into which compensating sleeves (12) can be inserted to accept electric motor output shafts of different diameters.
