  • Patent number: 10604425
    Abstract: The invention relates to a method for treating a liquid. A feed stream is separated into a permeate stream and a retentate stream by means of a member arrangement. At least a portion of the retentate stream is discharged from the member arrangement via a displacer arrangement as a defined displacer volume. The feed stream is divided into a portion that is fed into the membrane arrangement via a displacer arrangement as a defined displacer volume and into a portion that is fed to the membrane arrangement by means of a conveying unit. The yield is varied by changing the ratio of the speed of the conveying unit to the speed of the displacer arrangement.

  • Patent number: 6878358
    Abstract: Process for removing mercury from flue gases of high-temperature plants, in particular power stations and waste incineration plants in which a bromine compound is fed to the multistage furnace and/or the flue gas in a plant section downstream of the furnace, the temperature during contact of the bromine compound with the flue gas being at least 500° C., preferably at least 800° C. The combustion is carried out in the presence of a sulphur compound, in particular sulphur dioxide. Subsequently to the furnace, the flue gas is subjected to an optional multistage cleanup for removing mercury from the flue gas, which cleanup comprises a wet scrubber and/or a dry cleanup.

  • Patent number: 5407258
    Abstract: A circuit configuration for a vehicle with electronic anti-lock control having circuits for individual control of the braking pressure variation in the wheel brakes of the wheels of one vehicle axle and for limiting the yawing moment owing to braking pressure differences. Circuits (6) detect the pressure reduction signals (PA1, PA2) individually per wheel and determine the pressure difference (DA12) from these signals. In the case of different friction values (.mu.-split situation), the mean pressure build-up gradient at the high-value wheel is varied as a function of the pressure difference (DA12) and the vehicle deceleration. At the time of the appearance of the peak yawing moment, namely directly before the low-value wheel will reenter the stable range, the braking pressure at the high-value wheel will be reduced by a value dependent on the vehicle deceleration and on the pressure difference.
