In a method for preventing a collision of a vehicle with an obstacle located on its front (such as preferably another vehicle traveling in front of the vehicle), the headway between the vehicle and the obstacle and the difference in speeds of the vehicle and of the obstacle (relative speed) and also the speed and acceleration/deceleration of the vehicle are detected and a collision message and/or a braking operation is triggered as a function thereof. The driver's activity, the state of the road, the loading state and the degree of overlap of the vehicle relative to the obstacle are detected, and from this information, a first headway (D_brake) between the vehicle and the obstacle is calculated, which is the least necessary to avoid a collision of a vehicle with the obstacle by steering the vehicle past the obstacle. In addition, a second headway (D_steer) is calculated, which is the least necessary to avoid a collision by steering the vehicle past the obstacle. Automatic braking is initiated only when the detected headway is smaller than both the first and second calculated headway values, and when the degree of overlap

Polymers essentially comprising units of the formula I ##STR1## in which R.sup.1 and R.sup.2 are hydrogen or methyl andR.sup.3 is hydrogen, C.sub.1 -C.sub.18 -alkyl, C.sub.5 -C.sub.12 -cycloalkyl, C.sub.6 -C.sub.10 -aryl or C.sub.6 -C.sub.10 -aryl-C.sub.1 -C.sub.4 -alkyl, it being possible for these radicals, with the exception of the C.sub.1 -C.sub.18 -alkyl radicals, to be up to trisubstituted by radicals selected from the group consisting of C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy and halogen, are prepared by reacting a polymer based on C.sub.1 -C.sub.20 -alkyl esters of acrylic acid, methacrylic acid or mixtures thereof with ammonia or a primary amine in an extruder, by mixing the ammonia or the primary amine by mixing intensively with a melt of the polymer to be reacted, at at most 250.degree. C., before the imidation is carried out, and are used for producing thermoplastic moldings, films or fibers.
摘要:
The present invention relates to a discharge apparatus for a plant protection product with a container (1) which encloses an interior (7) for accommodating the plant protection product and which comprises a discharge orifice (9). The discharge apparatus according to the invention is characterized by a suction tube (3) which comprises a first orifice (10) in the interior (7) of the container (1), a second orifice (5) at the discharge orifice (9) of the container (1) and a third orifice (4) in the interior (7) of the container (1), which third orifice (4) is arranged at a distance from the first orifice (10), and a pump (2), which is in particular arranged in the interior (7) of the container (1) and is in operative connection with the suction tube (3), such that plant protection product located in the container (1) may be delivered by means of the pump through the suction tube (3) from the first orifice (10) of the suction tube to the second and the third orifices (5, 4) of the suction tube (3). The invention further relates to the use of such a discharge apparatus for discharging a plant protection product which is located in the interior (7) of the container (1).
