Abstract: A method for mounting a flap (3) on a workpiece (1) in a precisely positioned fashion, in particular for mounting a vehicle door on a vehicle body. A robot guided gripping tool (5) has a securing device (14) for holding the flap (3) and a sensor system (18) permanently connected to the gripping tool (5). In a first step, the gripping tool (5) is moved, within the scope of a positioning phase (A-2), from a proximity position (37), which is independent of the position of the workpiece (1) in the working space (27) of the robot (7), into a mounting position (29) in which the flap (3) which is held in the securing device (14) is oriented with respect to the workpiece (1) in a precisely positioned fashion. To move into the mounting position (29), an iterative closed-loop control process is run through, in the course of which firstly an (actual) measured value of the sensor system (18) is generated, which value is compared with a (setpoint) measured value which is generated within the scope of a setup phase.

Abstract: A method for processing a moving workpiece (1), in particular a vehicle body (1) which is moved using of a conveyor belt (10). A processing tool (5) is used which is attached to the hand (12) of a robot (7) and comprises a sensor system (18) which is permanently connected to the processing tool (5) and has at least one sensor (19). During the processing, the processing tool (5) follows the moving workpiece. This following movement is based on a closed-loop control process in which the processing tool (5) is oriented periodically towards reference areas (9) of the moving workpiece (1) using measured data of the sensor system (18).

Particularly advantageous in this case is the use of 5-formylthiazole which has been obtained by reaction of a 2-halomalonaldehyde compound with thioformamide in the presence of less than 5% by weight of water (based on the reaction mixture).

Abstract: An anti-theft device for a motor vehicle includes a key having a transponder. A lock has a keyhole for receiving the key. An antenna is in the vicinity of the lock. A control unit for controlling the antenna sends starting signals to the transponder and receives answer signals from the transponder. An assembly is turned on or off if the answer signals correspond to set-point signals. The antenna has a lighting device being controlled by the control unit for illuminating a region around the keyhole, at least before the key is inserted.
