Abstract: The invention relates to a method for determining the quality of an imaging plate, comprising the steps of carrying out an exposure of the imaging plate, carrying out a scan of the imaging plate in order to determine an image, determining a signal-to-noise ratio of the image or/and carrying out edge recognition on the image and calculating a quality value of the imaging plate on the basis of the signal-to-noise ratio of the image or/and on the basis of the recognized edge structure. Furthermore, the invention relates to an imaging plate scanner for carrying out such a method.

Abstract: A method for producing components from a duplex steel, and a component formed by the method, are provided. A powder-type duplex steel starting material including an austenitic phase and a ferritic phase is laser melted in successive layers to form a component. The melted and re-solidified component is then subjected to heat treatment to obtain solution annealing of the austenitic phase at a temperature range of between 850° C. and 1,100° C. for a predetermined dwell time, after which the component is cooled and the component has a grain size and grain size number G of at least 9 according to ASTM. The grain size and the grain size number G of the austenitic phase are influenced by the selection of the respective maximum temperature and/or the dwell time of the maximum temperature.

Abstract: A fluid conducting system with cathodic corrosion protection is provided for at least one device that influences and/or acts upon a flow rate, such as a pump and/or valve. The device includes at least one connection device such as a device connection flange. At least one flow rate guiding device such as a pipe includes a connection means such as a pipe connection flange. The system includes annular anodes arranged between the connection devices and connection means, where anodes are electrically connected by electrical conducting lines to a monitoring device. The internal diameter of the anodes is preferably equal to the internal diameter of the flow rate guiding device and/or the inner diameter of the inlet and/or outlet of flow influencing device.

Abstract: A device and a method for monitoring rotating components in centrifugal pumps or systems which comprise centrifugal pumps is provided. The device includes a first unit which is located on or in the component to be monitored having at least one component property sensor, a sensor signal evaluation unit, a transmitting unit for transmitting analysis results to a receiver arranged spatially separate from the monitored component, and a source for supplying power. The device further includes a second unit having a receiver unit, a transmitted signal evaluation unit, and a sensed component property display and/or information communication element. The analysis result transmission from the first unit to the second unit is acoustic.
