  • Insulation element with artificial fibres for electrical insulation in the high voltage range
    Patent number: 11075023
    Abstract: The invention relates to an insulation element (1) with low electrical conductivity for the electrical insulation of an electrotechnical component in the high voltage range. The insulation element (1) comprises artificial fibres (2) and electrically conductive particles (3) having an electrically non-conductive core (5) and an electrically conductive or semi-conductive cladding (6) surrounding the core (5). Moreover, the insulation element (1) comprises a cationic polymer (4).
    Type: Grant

  • Mobile x-ray apparatus
    Patent number: 5506883
    Abstract: A mobile x-ray apparatus has a support stand for an x-ray radiator which is mounted together with a control panel to form a unit. This unit is connected to a wheeled carriage so as to be pivotable around a vertical axis as a unit. This results in approximately the same weight distribution being present regardless of the angle at which the x-ray radiator is pivoted with respect to the supporting stand.

  • Driveshaft
    Patent number: 5243880
    Abstract: A driveshaft for a motor vehicle has an approximately constant wall thickness and a changing outer diameter which extends analogously to the amplitude of the second basic vibration of the natural bending frequency. In this way it is possible to achieve a distribution of cross-sectional area which is functionally optimized and meets the respective strength requirements. At the same time, torsional stiffness values may be set as required and natural resonance frequency values may be varied. With help of this design it is possible to move the natural resonance frequency of the tubular shaft into a speed range of minimum external excitation energy.
