Abstract: An item to be exposed to flue gas, especially a heat exchanger (10) to recover additional heat and in which condensation will form, is given a protective coating of thermosetting synthetic resin to prevent attack by acid in the condensation. The coating is preferably applied by dipping into a heat-curable paint, drying the paint under moderate heat while rotating about two axes to prevent "solvent wash" and to ensure that no localised thinning of the coating can occur, then stoving, preferably also under rotation, to produce a finished hard coating of synthetic resin.

Abstract: A system for presetting register and color zone adjusting devices in a multi-color rotary printing machine uses digitally-driven optical scanners axially traversing the plate cylinders under control of at least one numerical computer. Machine-specific characteristics are programmed in non-volatile memory as referenced values. Data processing is not required to be conducted external to the printing machine. The system is compact and requires practically no re-adjustment or entry of desired values from the machine operator. The machine operator, however, may enter coordinates for printing areas on the printing plate in order to speed up the scanning process for determining the initial color zone preset. The scanner multi-functionally scans the printing plate for both register adjustment and for integrating the ratio of printing to non-printing area for each inking zone. The system is easily reprogrammed and the optical scanner is interchangeable with a densitometer in order to provide alternative control functions during printing, such as the regulation of inking and dampening.
