摘要:
A method for color regulation of reproduction copies of a printing press prints a substrate, which appears dark in a standardized color measurement, with at least one printing ink which is lighter than the substrate. At least one color value of the printing ink is determined from a measured variable, and the color value of the at least one printing ink is regulated with the aid of a fixed reference value of a color locus in the color space which is lighter than the printing ink.
摘要:
The invention is directed to a method and an arrangement for controlling an internal combustion engine wherein a signal representing engine load is compared to a maximum value pregiven for at least one driver command range. Fault and emergency reactions are initiated when the measured signal value reaches or exceeds the maximum value.

An apparatus comprising a control device of a driving engine which can be actuated purely mechanically, for varying the operation of engine as well as via a control motor as needed, independently of the mechanical operation in a direction of reduced output of the driving engine. The apparatus includes a restoring spring which acts upon a first driver element connected to the operating element. Since the coupling spring is not subject to tension exerted by the restoring spring, the coupling spring can be embodied as relatively weak. The apparatus is particularly well-suited to motor vehicles equipped with traction control.

摘要:
A method for color control in printing presses having at least one first color measuring instrument and at least one second color measuring instrument, includes registering at least one first inking zone on a printing material with the first color measuring instrument and registering at least one other, second inking zone on the printing material with the second color measuring instrument. In a first step, a color difference between actual colorations of the first and second inking zones is calculated, in a second step, a color difference between an actual coloration of the first inking zone and a desired coloration of the second inking zone is calculated and, in a further step, the calculated color differences are added and supplied to a color control for the second inking zone.
