Title: Registering and controlling quality of printed product - evaluating over spectral range of 400 to 700 nanometres and evaluating individual colours upon detection of fault
Inventor: MORGENSTERN BERND
IPC: B41F33/00
Filed: 1990-07-21
Abstract: In a prim. phase a faulty sheet is detected by a first spectral channel operating over the complete spectral range of 400 to 700 nm for uniform evaluation.  When a fault (4) is detected by a rise in signal level (A"), the three other spectral channels are applied for evaluation of the separatee colours. The coordinates of the fault location are delivered to an image analysing and expert system computer.  After a set number of fault examples in a sec. phase, the actual images are transferred to the image analysing computer in pixel format.  The fault type and preventive measures to be taken are derived from the expert system computer. USE/ADVANTAGE - Rapid measuring for ascertaining cause of printing faults and simple associated correction.

Patent DE-4112356-A1 (DE)
Inventor: KANITZ JUERGEN
IPC: G01N21/3518
Filed: 1991-04-16
Abstract: The present invention relates to a method and an apparatus for determining the concentration of substances in gases. The method employs electromagnetic irradiation and measurement of the transmitted radiation intensity at a wavelength characteristic of the substance to be determined, the gas containing the substance being measured at not less than two different gas pressure values. In order to overcome the disadvantages of conventional methods, which without exception employ reference gases which have to be specially prepared and stocked, and in order, nevertheless, to be able to determine very rapidly and simply the concentration of a substance in a gas with a relatively high precision, the invention proposes that an initial measurement is carried out at an essentially constant first pressure of the gas to be analysed, then the gas pressure is altered and a second measurement is carried out at a second constant gas pressure with an otherwise identical measurement system, and that the concentration of said substance in the gas is determined by calculation or graphically from the ratio of, or the difference between, the intensities measured in these two measurements on the basis of a theoretical relationship between the absorbance and the concentration by volume of the substance concerned. <IMAGE>
