Das Düsenstrahlverfahren (DSV) ist eine Form der Baugrundinjektion zum Erstellen von Zement-Bodengemisch-Körpern im Erdreich. Bei den Düsenstrahlarbeiten im Düsenstrahlverfahren ergibt sich verfahrensbedingt ein Rücklauf, welcher einen hohen Zementanteil aufweist. Dieser Rücklauf wird üblicherweise praktisch ungenutzt entsorgt. Es ist Aufgabe der Erfindung, einen Messaufbau für eine Rücklaufzementsuspension, eine Baustellenanordnung mit einem oder dem Messaufbau und ein Verfahren vorzuschlagen, welcher/welche/welches kostengünstig, zuverlässig und einfach ausführbar ist. Insbesondere wird ein Messaufbau 13 für eine Rücklaufzementsuspension vorgeschlagen, mit einer Messmischeinrichtung 20 zur Vermischung einer Rücklaufzementsuspension mit einem Zusatzmittel zu einer Testsuspension, mit einem Messstreckenabschnitt 22, mit einer Messvorrichtung 26 zur Messung von mindestens einer Hauptmessgröße, wobei die Hauptmessgröße abhängig von den rheologischen Eigenschaften der Testsuspension ist, und mit einer Auswerteeinrichtung 29, wobei die Auswerteeinrichtung 29 ausgebildet ist, in Abhängigkeit der Hauptmessgröße mindestens eine Qualitätskennzahl für die Rücklaufzementsuspension zu schätzen und/oder zu bestimmen.

The present invention relates to a coating device (9) comprising a coating head (D) or application chamber, which applies a water-based coating to a workpiece, wherein an air flow (10) is fed into said coating head (D) or said application chamber, wherein said air flow regulates the layer thickness of the coating layer on the workpiece. The present invention further relates to a method for coating and a means for determining the state of a water-based coating.
摘要:
A sensor device (10) and a method for measuring a viscosity of a sample of a liquid. The sensor features a chamber (12) for receiving the sample of the liquid, two electrodes (18) disposed either on the surfaces of the chamber, but possibly isolated from contacting the sample, or electrodes located externally to the chamber, and a capacitance measuring circuit (25). The sensor is used by connecting to a measurer for determining a capacitance on the electrodes, such that the capacitance directly reflects a volume occupied by the sample of the liquid. Preferably, the liquid is blood and the capacitance is used to determine the clotting time of the blood. Also preferably, a cover for the chamber is provided with at least one aperture, which more preferably is a mesh. Alternatively, an electrical property such as the amplitude of current passed through the sample is used to determine clotting time. Also preferably, the time period required for the maximum capacitance to be reached could be measured. Alternatively, the capacitance could be measured after a fixed time period (34) had elapsed. Also alternatively, the time period required for the maximum current to be reached could be measured, or the amount of current could be measured after a fixed time period had elapsed. In preferred embodiments of the present invention, a kit for measuring the clotting time of blood is provided. In other preferred embodiments of the present invention, methods are provided for using the kit and device of the present invention.
