Abstract: The invention relates to a process for controlling the addition of an auxiliary fuel to combustion of at least one combustible material in a combustion chamber. In addition, the invention relates to the use of the process, in which the concentration is measured in the flue gas of at least one pollutant formed by incomplete combustion. In a second step, the rate of the auxiliary fuel fed to the combustion is increased when the concentration of the at least one pollutant in the flue gas exceeds a predetermined upper limiting value, or is decreased when the concentration measured of the at least one pollutant falls below a predetermined lower limiting value. Measurement of the concentration and setting the rate of the auxiliary fuel is repeated until the measured concentration of the at least one pollutant in the flue gas is in a range between the lower and upper limiting values.

Abstract: A method is provided for detecting not fully set coatings and liquid or smearing impurities on a surface, in which in a first step a film is pressed onto a surface of a coating using a predefined press-on pressure, the film having a relative motion with respect to the surface of the coating, thereafter the film is pulled off the surface of the coating and finally it is determined whether impurities are adhering to the film. A device is also provided for performing the method, including at least one film, which may be pressed against a surface to be tested, at least one press-on roller having a surface by which the film is pressed against the coating, and at least one device for determining whether there are impurities adhering to the film.

Abstract: In a method for evaluating mechanical tests of a coating on a substrate, in a first step a mechanical stress is applied onto the coating, in a second step the substrate having the coating is isothermally clamped, in a third step an infrared photograph is generated of the region in which the mechanical stress is applied onto the coating in the first step, and in a fourth step the infrared photograph is evaluated. A device is arranged for carrying out the method.

Abstract: A method and a system for context-based real-time advertising are provided. In example embodiments, a document content that is displayed to a user may be analyzed and keywords may be identified. Selected listings from a publication system may be received; the selected listings may be selected using the keywords. The system may detect user events associated with the keywords and, in response to the detection of the user events, display information related to the listings while maintaining the displaying of the document content.

Abstract: A device for testing material properties with regard to combined tensile and shear loads, in particular for testing adhesives, includes a device for applying the force, a measuring device, a test piece receptacle, and a test piece having a bonding surface. The test piece is dimensionally stable within the intended limits of the force to be applied. This measure ensures that the shear forces acting on the joint act approximately at a right angle to the bonding surface over the entire test period, so that realistic conclusions may be drawn with regard to the material properties of the tested adhesive.
