摘要： A method for continuous overall regulation of a former of a paper or board machine or equivalent in which a physical fluid flow model of the drainage and the flow state of the pulp suspension flow is formed. The model is solved by making use of the data on the geometry of the former and initial and boundary conditions necessary for a solution to the model. The difference between the simulated state, which has been obtained as the solution of the physical flow model, and the state adopted as the target is determined as the cost function, wherein the target state is determined by means of the quality requirements of the paper and possibly by means of the costs of operation and the runnability of the paper machine. The cost function is optimized and, thus, optimal regulation values and set values are obtained for the regulation devices and/or actuators of the former in view of the given cost function. After the optimization has been carried out in the preceding stage, the former's regulation devices and/or actuators are given new optimal regulation and set values.

摘要： A multi-layer headbox for a paper or board machine including stock inlet headers each providing one stock and coupled to a tube bank which in turn is coupled to a respective intermediate chamber. The stock flows from the intermediate chambers into a turbulence generator and through pipes in the turbulence generator into a slice cone to be discharged therefrom onto a forming wire. The multi-layer headbox includes distribution valves for regulating the flow of dilution water across the width of the headbox. Each distribution valve communicates with a distribution plate placed in connection with the tube bank. From each valve, the dilution liquid is distributed at the same time to all the stocks that form the different layers of the web in the multi-layer headbox at a specific position of width of the multi-layer headbox.

摘要： A multi-layer headbox including at least two inlet headers for stock through which separate stocks are passed into a system of distributor pipes and further through a turbulence generator into a slice cone narrowing in the stock flow direction. Flaps are placed in the slice cone and one end of the flaps is attached to the turbulence generator. The flaps have at least two flap faces between which a step is formed. The step is arranged on the flap in an area in which the flap, and the flow duct, is curved and its the function is to dissipate any secondary vortices that might form on the curved flap face.

摘要： A method and device for the regulation of a pulp suspension flow in a multi-layer headbox and a multi-layer headbox for a paper machine/board machine. For the formation of different layers in the web, at least two pulp suspensions having different pulp concepts flow through the multi-layer headbox. The flow of a pulp suspension that forms one of the layers in the web is regulated by regulating the component flows that constitute this flow and regulating the concentration of the component flows independently from one another. In this manner, i.e., by regulating only this the particular layer, the total flow of the pulp suspension leaving the headbox is regulated.

摘要： A method for the continuous overall regulation of a single-layer or multi-layer headbox of a paper, board or pulp-draining machine. A physical fluid flow model of a pulp suspension flow discharged from the headbox to be regulated is formed and solved to obtain a simulated flow state based, e.g., on data on the geometry of the headbox and initial and boundary conditions related to the headbox. A target flow state based on the quality requirements of the paper produced from the pulp suspension flow and the costs of operation and runnability of the machine is obtained and a difference between the simulated flow state obtained as the solution of the flow model and the target flow state is determined. This difference constitutes a cost function which is optimized to determine optimal regulation values and set values for instrumentation devices and actuators of the headbox which affect the pulp suspension flow. The optimal regulation and set values are provided to the devices and actuators of the headbox such that the devices and actuators of the headbox may operate at the optimal regulation and set values.

摘要： An attenuator for radio frequency applications includes variable shunt elements and series transmission elements. The impedances of the variable shunt elements and the series transmission elements are selected so that the impedance of the attenuator at the input terminal remains at a nominal value for all attenuation levels, thereby producing low loss at high frequencies. The use of the attenuator as a switch yields a non-reflective switch at radio frequencies.
