  • Patent number: 6446490
    Abstract: Device and method for determining a wheel braking pressure and/or an admission pressure in a braking system in which pressure medium is introduced from a reservoir for the pressure medium having an admission pressure into a wheel brake through at least one shutoff device for inlet and/or outlet and/or passage of a pressure medium, it being possible to remove pressure medium from the wheel brake through at least one means delivering the pressure medium. In so doing, a pressure quantity representing the admission pressure is estimated, at least one operating state of at least one actuator in the braking system is detected and the wheel braking pressure is estimated as a function of the estimated admission pressure and the detected operating states.

  • Patent number: 6228222
    Abstract: A method for the treatment of a material web and a press arrangement with a plurality of press gaps. A roll has a flexible press jacket supported from an inside, and forms a respective press gap with each of at least two further driven rolls. The drive power, or speed of one of the driven rolls, is regulated in accordance with a predetermined desired value, to ensure a common speed of the driven roll. A maximum line force and/or drive power of a front press gap, considered in a web running direction, is controlled and/or regulated, at least within a certain range, in accordance with a maximum line force, or drive power, of a rear press gap, considered in the web running direction.
