摘要： The invention relates to a method for optimizing the energy balance of a forming section in a machine for producing fibrous webs, in which a fiber suspension, which is fed to the forming section by way of a material ramp after the immobility point is reached, is passed through at least two dewatering units within a compression zone and to a subsequent functional unit. The invention is characterized in that a setpoint value for a target dryness to be set is predefined based on the existing dewatering elements as a function of a theoretical maximum achievable dryness under plant conditions in the area of the transition zone, said setpoint being selected such that it is less than the theoretical maximum achievable dryness but is equal to or greater than a required minimum dryness in the area of the transition zone, and that the target dryness is controlled by lowering the inlet dryness at one of the last dewatering units disposed in the direction of passage of the fiber suspension within the compression zone.

摘要： This invention relates to a dewatering apparatus, in particular a paper machine or a paperboard machine, for the adjustable, and controllable dewatering of a fibrous material, which is conveyed as a fibrous web that can be divided into at least two zones arranged side by side in a cross direction (CD). The dewatering apparatus is characterized in that the dewatering of the fibrous material is adaptable to a dewatering curve defined in a machine direction on the basis of measurements of the water weight of the fibrous material taken by at least two water weight sensors, in particular a one-dimensional or multi-dimensional sensor arrangement of water weight sensors, which are assigned to a zone and arranged preferably in pairs in mutually offset position in the CD direction.

摘要： The invention provides a fault tolerant output stage for a digital two-conductor bus data communication system of the type having a transmission module and a reception stage which contains a bus signal intermediate processing module and a reception module connected downstream that conditions incoming bus signals for a data processing unit which is connected downstream. A state detection module is connected to the bus lines to detect a short-circuit between the bus lines, in which case the transmission module can be switched over between a difference mode of operation and a single-wire mode of operation under the control of the state detection module. The intermediate processing module is configured to condition the bus signals for the reception module automatically or under the control of the state detection module, both in the case of fault free bus lines and in the case of an interruption or short-circuit to the high or low supply voltage of one of the two bus lines and in the case of a short-circuit of the two bus lines to one another.
