  • Patent number: 4210976
    Abstract: The device for removing incrustations from the inner wall of a cylindrical vessel comprises a driven shaft supported for rotation in the vessel about its central axis and for a vertical movement along this axis. Impact tools, preferably in the form of prismatic blocks defining a straight edge, are attached respectively to the shaft by a pair of chains in such a manner that the abrading edge of each tool extends parallel to the central axis when the chains are straightened by the centrifugal force.

  • Patent number: 4106709
    Abstract: A helical induction coil of large diameter which is to be served with a protective band is suspended from a driving roller having a substantially horizontal axis of rotation so that the coil axis is substantially horizontal. A serving device is supported on the respective convolution to be served and also on immediately adjacent convolutions at the lowermost region of the coil for advancement in the longitudinal direction of the convolutions. Spreading rollers spread the immediately adjacent convolutions from the respective convolution to permit the serving device to advance. The driving roller frictionally entrains the coil and thus rotates the same about the coil axis and the spreading device is advanced at the same speed as but in the opposite direction than the respective convolution so that the position of the serving device diametrally opposite to the driving roller relative to the coil is maintained.
