  • Patent number: 10792670
    Abstract: A method for fragmenting and/or weakening of pourable material by means of high-voltage discharges is disclosed. Thereby, a material flow of the pourable material is, immersed in a process liquid, guided past a high-voltage electrode assembly with one or more high-voltage electrodes, while high-voltage punctures through the material are produced by means of charging of the high-voltage electrodes with high-voltage pulses. The zone of the material flow in which the high-voltage punctures through the material are produced is delimited laterally by substantially unmoved zones of the same material as viewed in a guiding-past direction. With the disclosed method, it becomes possible to fragment and/or weaken pourable material in a continuous process by means of high-voltage punctures in a low-wear and low-contamination manner.

  • Patent number: 10780474
    Abstract: A metal band is first rolled in a front and then in a rear (downstream) roll stand of a multi-stand rolling train. A looper between the roll stands may detect a band tension in the metal band. The band tension is supplied to a first and a second tension controller to determine an application additional target value and a speed additional target value. The second tension controller may only determine a value less than or greater than 0, as the speed additional target value, if the band tension is above or below an upper or lower band tension limit. Otherwise, the speed additional target value may be 0. The first tension controller is also supplied with a target tension that falls between the band tension limits. The application additional target value may be used to act on the rear roll stand.
