    Abstract: The present invention refers to a process for the preparation of supported catalysts for the polymerization of olefins comprising at least a late transition metal complex, wherein the process comprises two steps. In the first step a catalytically active component comprising at least one late transition metal complex, optionally in the presence of one or more cocatalysts is mixed with a support; and in the second step the obtained mixture is treated at a reduced pressure under a flow of inert gas at a temperature equal to or below 40° C. to obtain a supported catalyst. The method is especially useful for the preparation of dual supported catalysts, useful in the gas-phase polymerization of olefins.

    Abstract: A method of controlling a clutch in a motor vehicle and a motor vehicle adapted to perform this method are suggested, in particular resulting in a good starting phase action for supercharged diesel motors. The method comprises the method steps of: setting a clutch torque that is transmitted by a clutch by a plurality of clutch characteristics; determining by a respective clutch characteristic the clutch torque for a particular motor load depending on the rotational speed of the motor; dividing the clutch characteristics into a low speed range and into a full load range; increasing within the low speed range at a constant rotational speed of the motor the transmitted clutch torque with increasing the motor load; and transmitting in the full load range in comparison to the low speed range lower clutch torques at the same rotational speed of the motor.

    Abstract: A method for shifting gears in a dual clutch transmission within a motor vehicle and a motor vehicle implementing said method are suggested providing a smooth transition between gears particularly in the starting phase. The dual clutch transmission comprises a first clutch and a second clutch as well as a first partial transmission having a first and other gears and a second partial transmission having a second and other gears. The clutches are controlled to a) decrease a torque transmitting capacity of the first clutch; b) increase a torque transmitting capacity of the second clutch; c) adapt the rotational speed of the motor in direction of a rotational speed of an input shaft of the second partial transmission via increasing the torque transmitting capacity of the second clutch; and d) control the torque transmitting capacity of the second clutch to a final torque value.
