Abstract: A method/device for controlling a traction vehicle-trailer brake device, a trailer with an unactivated service brake is detected, and when a predetermined pushing effect is reached/exceeded a trailer brake system is activated to generate a braking force when the service brake is unactivated, in which the first parameter is a) consumption of an operating medium, and/or b) torque generated by a drive machine/driven wheel, and/or c) signal representing the traction vehicle/trailer's longitudinal deceleration, and/or d) the speed/acceleration at which an activation element is activated toward lower velocities, and/or e) a difference/quotient of a target traction vehicle speed, and an actual traction vehicle speed is used if the traction vehicle having an infinitely variable transmission, and provides infinitely variable adjustment of the transmission ratio, and f) the control device detects that the predetermined pushing effect of the trailer is reached/exceeded if a first parameter predetermined limiting value i

Abstract: A method and device for controlling a brake device in a traction vehicle-trailer, wherein a trailer which pushes onto the traction vehicle is detected by a control device in a driving state with an unactivated service brake, and when a predetermined pushing effect of the trailer is reached or exceeded a brake system of the trailer is automatically activated by the control device to generate a braking force when the service brake of the traction vehicle is not activated, in which the first parameter that the control device uses for detecting the pushing of the trailer onto the traction vehicle or to form this first parameter is a) the consumption of an operating medium for operating a drive machine of the traction vehicle and/or b) the driving torque generated by a drive machine of the traction vehicle and/or the output torque at at least one driven wheel of the traction vehicle, and/or c) a signal representing the longitudinal deceleration of the traction vehicle and/or a signal representing the longitudinal

Abstract: A process for the production of aromatic carbodiimides by carbodiimidization of aromatic monoisocyanates in the presence of distillable organic phosphorus compounds as catalyst at 120.degree. to 220.degree. C. up to a maximum degree of carbodiimidization of 80% and subsequent removal by distillation of the unreacted starting isocyanate together with the catalyst from the reaction mixture, optionally together with subsequent preparation by distillation, together with the carbodiimides obtainable in accordance with this process.
