Patent DE-4039818-A1 (DE)
Inventor: MUELLER JOACHIM
IPC: B41F33/00
Filed: 1990-12-13
Abstract: The invention relates to a method for controlling inking of printed products which are produced on a printing machine operating by autotypy, in particular a sheet-fed offset printing machine. Also printed on the print sheet is a print control strip, which contains a measuring field of specific halftone value for each ink to be printed in each ink metering zone and, additionally, a full-tone measuring field in at least one ink metering zone. If the inking is to be tuned to a prescribed desired area coverage (FDSoll), the Murray-Davies formula is used to calculate desired halftone ink densities (DRN1Soll, DRM1Soll) from the full-tone ink densities (DVN1, DVM1) measured on the full-tone measuring fields. If more than one full-tone measuring field is present in the print control strip, it is possible, on the one hand, to average over these desired halftone ink densities (DRN1Soll, DRM1Soll) calculated in this way, the mean value then being used as desired halftone ink density for all ink metering zones to be controlled. On the other hand, it is possible if more than one full-tone measuring field is present in the pressure control strip to average over the measured full-tone densities (DV), and then to use the Murray-Davies formula to calculate a new desired halftone ink density value. Thus, in each control operation new desired halftone ink densities are calculated, and the ink metering zones are controlled accordingly.

Title: Method for extinguishing burning oil well - involving prodn. of fire wall and use of guided introduction of fluid inert gas into centre of fire and withdrawal of oxygen@ from air
Inventor: MUELLER HEINZ
IPC: A62C3/02
Filed: 1991-04-04
Abstract: Appts. is used to produce a fire wall surrounding the burning oil source. The combustible material for the wall can be gas-form or liq., and is applied with pressure. Varying local conditions of burning oil sources can require several ring-shaped devices of varying dias. at various heights. Also used is a device for the targeted introduction of a fluid inert gas into the centre of the fire, e.g. in the form of a rollable and extendable pipe conduit. The fire wall causes a withdrawal of air oxygen required for the oil to burn, thereby extinguishing the flame. The liq. inert gas adheres to surfaces in the region of the extinguished flame, thereby having a cooling effect and preventing a recurrence of the fire. ADVANTAGE - For extinguishing burning oil wells.
