    Assignee: Udo Dolezych
    Inventors: Udo Dolezych, Rupprecht Graf
  • Patent number: 4915434
    Abstract: An apparatus is provided to shorten and/or fasten flat belts or straps for wrapping and hoisting a load. The apparatus includes a vertical base plate having a crane lug located in its upper portion. Also, at least three deflectors with free ends are mounted in spaced apart relation on the plate so as to project generally perpendicularly therefrom. The free ends of the straps or belts are inserted into the apparatus and pulled between and looped about the deflectors in a meandering fashion to affix the belts to the apparatus before hoisting the load.

  • Patent number: 4309215
    Abstract: A method for the cementation of a metal from a solution containing metallic ions by the addition of a finely divided cementation medium, wherein the cementation reaction is carried out in a reaction chamber located in an oscillating reactor which is at least partially filled with agitation bodies inert with respect to the reaction, the agitation bodies having a maximum dimension in the range from 2 to 150 mm and being sufficiently large to transmit the oscillations of the reactor into the reaction chamber, the specific gravity of the bodies being appreciably greater than the specific gravity of the solids in the reactor. The method is particularly applicable to the cementation of copper.

    Inventors: Reinhard Nissen, Rupprecht Graf
  • Patent number: 4283938
    Abstract: In the dynamic concentration of a suspension, in which the suspension is fed into a filter which has a driven stirring device, and in which the suspension forms a filter cake which is continually remixed by stirring with the suspension being dehydrated and maintained in a liquid state up to a desired degree of concentration, the power consumption of the stirring device is measured, in particular the torque is measured, and the intensity of the stirring motion is controlled in accordance with the measured torque by causing a change in the number of revolutions per minute of the stirring device in response to the torque transgressing an upper limit or a lower limit.

    Inventors: Wolfgang Epper, Rupprecht Graf
  • Patent number: 4270466
    Abstract: Method and apparatus for operating a process in which combustible solid particles are mixed during processing with air and circulated through a plurality of stages, thereby tending to build up an oxygen enriched combustible mixture during shutdown, the invention involving adding additional fuel to the oxygen enriched combustible mixture during such shutdown in a closed burner system, burning the resulting mixture in the closed burner system, and recirculating the flue gas from such combustion back into the plurality of stages to thereby function as an inert gas to prevent accidental combustion or explosion.

    Assignee: Klockner-Humboltd-Deutz AG
    Inventors: Jakob Ansen, Helmut Duill, Heinz Fasbender, Rupprecht Graf
  • Patent number: 4266982
    Abstract: A method and apparatus are disclosed for cleansing a matrix of a magnetic separator and more particularly a wet-magnetic separator having adherent magnetic material. The matrix is cleansed both with a liquid medium and an additional gaseous compressible medium. The introduction of the compressible medium is controlled in accordance with a measure of the adherent magnetic material present.
