摘要:
A process for pretreating cellulosic textile, which comprises the steps of: (a) treating cellulosic textile with a solution of polymer or copolymer obtainable by (a1) polymerization or copolymerization of N-vinylamide of the general formula I where R is selected from hydrogen and C1-C10-alkyl, and (a2) partial hydrolysis if appropriate, (b) optionally drying the treated textile, and (c) optionally saponifying all or some of the amide groups, wherein at least one of the steps (a2) and (c) is carried out.

摘要:
A device for a motor vehicle includes at least one laser sensor. The laser sensor includes a device configured to sweep a scanning area with at least one laser beam emitted by the laser sensor and a power supply device for the laser sensor. In a method for operating a laser sensor in a scanning area with at least one laser beam, the power of the laser beam emitted by the laser sensor is varied in accordance with its direction of radiation.
摘要:
A method and arrangement for controlling vehicle spacing produces driver-specific characteristic diagrams for vehicle speed and following time from which a mean target following time is determined. The characteristic diagrams are used to control the spacing of the vehicle from a vehicle in front of it.
