Abstract: The invention relates to a method and a device for controlling the cornering speed of a vehicle, with determination of the lateral acceleration and of the speed of the vehicle. In order to achieve a simple but effective capability of adjusting the vehicle speed to an optimum value, the yaw angular velocity is additionally determined, and a body slip angle is determined from the lateral acceleration, yaw angular velocity and vehicle speed. The body slip angle is compared with a threshold value. If the body slip angle exceeds this threshold, the set speed of the vehicle is reduced from the instantaneous actual speed, in a manner proportional to the body slip angle. If the body slip angle is below the threshold, the speed is released once again, or in other words the set speed is carried to the actual value of the speed; the driver can then accelerate once again. Adjustment of the set speed is achieved via adaptation of the engine torque.

Abstract: The invention relates to a permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material contains essentially a porous, permeable support, another constituent having been solidified on and in or on or in said support. Said other constituent essentially contains metallic compounds with elements of the 3rd to the 6th main group. The constituent is solidified to, on or in the support by heating a suspension of the constituent suspended in a metal oxide sol applied on and in or on or in the support. The invention hereby provides a means of producing a permeable composite material in very mild conditions, either by heating strongly for a short period or by heating more moderately for a longer period.

Abstract: Nitrosylsulphuric acid is mixed in a mixing reactor with sulphuric acid saturated with SO2. The acid mixture is led into a saturating reactor into the bottom region of which water and an SO2-containing gas are introduced. The gas partially serves as stripping gas inside the saturating reactor. SO2-saturated, Nox-free sulphuric acid with 5 to 60 wt % H2SO4 is removed from the bottom region of the saturating reactor and part thereof is mixed with nitrosylsulphuric acid in the mixing reactor.

Abstract: A process is provided for manufacturing sulfuric acid from a gas containing sulfur dioxide and steam. The sulfur dioxide and steam containing gas is subjected to a catalytic oxidation to convert the sulfur dioxide into sulfur trioxide so as to produce a gas having a sulfur trioxide to steam mole ratio of at least 1:1 at a temperature of 400 to 600.degree. C. This sulfur trioxide and steam containing gas is injected into an indirect heat exchanger where it is indirectly cooled with a cooling fluid so that at least 80 percent of the theoretically possible sulfuric acid is formed and condensed in this heat exchanger. The cooling fluid exiting the heat exchanger is fed into a turbine for the generation of electricity. The gas mixture exiting the heat exchanger is contacted with sulfuric acid in a separate contact vessel to form additional, concentrated sulfuric acid. The sulfuric acid formed in the heat exchanger is discharged.
