  • DOSING PUMP FOR DOSING ANTISCALANT INTO A MEMBRANE-BASED WATER TREATMENT SYSTEM
    Publication number: 20220127163
    Abstract: A dosing pump (19) doses antiscalant into a membrane-based water treatment system (1). The dosing pump (19) includes a displacement body for pumping antiscalant into the membrane-based water treatment system (1) in doses. A motor drives the displacement body. A control module controls the motor. The control module is configured to vary the dosage of antiscalant pumped into the water treatment system (1) based on a temperature corrected system variable (SVTc) being based on a plurality of operating variables of the water treatment system (1).

  • Display device and lenticular screen
    Patent number: 6667786
    Abstract: The invention relates to a display device comprising LC panels arranged next to each other. To reduce the visibility of a seam between two adjacent LC panels and to avoid grey scale inversion, collimated light is applied. A lenticular foil is used to enlarge the viewing angle in the horizontal direction. If the seam is only present in a vertical direction, the widest viewing angle in the vertical direction should be chosen. This choice leads to an asymmetric viewing angle in a horizontal direction. To reduce the asymmetry in the horizontal viewing angle, the lenticulars of the screen have a trapezoidal shape. The apex angle depends on the desired spread and viewing angle symmetry in the horizontal direction.
