Abstract: The invention relates to a device serving for the combined measurement of the width and thickness of a flat object, in particular a plate, a belt, or a web. The device comprises a measurement apparatus which has at least one contactless sensor, which is for width measurement on the object and which is movable crosswise to the longitudinal direction or conveying direction of the object. According to the invention, on the opposite side of the object, there is a second sensor opposite the first sensor which, together with the first sensor, serves for thickness measurement on the object, wherein the two sensors can travel above and below the object, that is, on opposite sides of the object.

Abstract: The invention relates to an apparatus for the inline trace analysis of a liquid, preferably of an aqueous process solution, comprising: a housing (1); a micro-channel (2) through which the liquid to be examined is allowed to flow and into which light of a light source (3) is coupled; a detector (4) for light emerging from the micro-channel (2); and a user interface (5) for monitoring and/or operating the apparatus. The micro-channel (2), the detector (4) and/or the user interface (5) are arranged in the housing (1) and/or are integrated into the housing (1), and the housing (1) has a connection (6) for feeding the liquid in the micro-channel (2) and a connection (7) for power supply of the apparatus.

Abstract: An apparatus for measuring the thickness of a measurement object, preferably a measurement object in the form of a web or piece goods, in a measuring gap, with a measuring mechanism which is fitted to a machine frame, wherein the measuring mechanism for measuring the thickness comprises one or more travel measurement sensor(s) aimed at the measurement object, is characterized in that a compensation sensor which is coupled to a travel measurement sensor measures the distance to a reference rule in order to detect and compensate for a change in the measuring gap, in that the reference rule is in the form of a side of a frame-shaped reference device integrated in the measuring mechanism, and in that the reference device is configured in such a manner that the distance between the reference rule and that side of the reference device which is opposite the reference rule is known during the thickness measurement. A corresponding method for measuring the thickness is also stated.

Abstract: A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.
