Abstract: A method for determining changes of a site, wherein the site is treated with an aqueous dispersion having at least one binder, at least one substance emitting visible light on UV exposure, at least one binder and, optionally, a dispersant and the site thus treated and/or untreated adjacent sites are exposed to UV light and the deviation of the light intensity of the emitted light of a partial area of the site from the mean light intensity of the emitted light of the site area and/or the light intensity of the emitted light of a part of the adjacent, untreated area from the mean light intensity of the emitted light of the adjacent untreated areas and/or the light intensity of the emitted light of the site immediately after the treatment with the composition from the light intensity of the emitted light at a later time and/or the light intensity of the emitted light of the adjacent untreated area immediately after the treatment of the site with the composition from the light intensity of the emitted light of th

Abstract: A composition and a method for determining changes of a site. The composition includes an aqueous dispersion including at least one binder, at least one substance emitting visible light on UV exposure and optionally a dispersant. The method includes treating the site with a composition, exposing the treated site and/or the untreated areas adjacent thereto to UV light, and determining the deviation of the light intensity of the emitted light of the site Immediately after the treatment with the composition from the light intensity of the emitted light at a later time.

Abstract: A method for determining changes of a site, which is characterized in that a) the site is treated with a composition and b) the site thus treated and/or the untreated areas adjacent thereto are exposed to UV light and the deviation b1) of the light intensity of the emitted light of a partial area of the site from the mean light intensity of the emitted light of the site area and/or b2) the light intensity of the emitted light of a part of the adjacent, untreated area from the mean light intensity of the emitted light of the adjacent untreated areas and/or b3) the light intensity of the emitted light of the site immediately after the treatment with the composition from the light intensity of the emitted light at a later time and/or b4) the light intensity of the emitted light of the adjacent untreated area immediately after the treatment of the site with the composition from the light intensity of the emitted light of the adjacent, untreated area at a later time are determined, the composition being an aqueous

Abstract: A harvester has a thresher for receiving at an intake a mixture of straw and grain and for separating the mixture into grain, straw, and tailings comprised of mixed grain and straw and a conveyor recirculates a stream of the tailings along a path back to the intake. A sensor is positioned in the path and intercepts at least a portion of the stream for counting a number of grains in the portion of the stream passing the sensor. The conveyor includes an elevator for raising the tailings stream to a location above the sensor and for dropping the tailings stream on the sensor. The thresher includes a main threshing drum and a cleaning unit downstream therefrom.

Abstract: Water-soluble homo- and/or copolymers containing alkali metal and/or alkaline earth metal carboxylate groups and based on acrylic or methacrylic derivatives, and corresponding water-soluble homo- and/or copolymers containing carboxyl groups and homo- and/or copolymers containing ammonium carboxylate groups are provided, which homo- and/or copolymers possess excellent suitability for increasing the viscosity of aqueous systems, in particular of print pastes for textile treatment.
