Abstract: An example system for analyzing a component includes a radiation source configured to transmit an input radiation beam towards a component, at least a portion of the input radiation beam passing through the component as an output beam pattern; a radiation detector configured to detect the output beam pattern; and a beam adjustment device disposed between the radiation source and the component and configured to modify a radiation intensity profile of the input radiation beam, wherein the beam adjustment device has an adjustable radiation transparency. A method of analyzing a component is also disclosed, which includes transmitting an input radiation beam from a radiation source towards a component, at least a portion of the input radiation beam passing through the component as an output beam pattern; modifying a radiation intensity profile of the input radiation beam by passing the input radiation beam through a beam adjustment device disposed between the radiation source and the component, wherein the beam adjustment has an adjustable radiation transparency; and detecting the output beam pattern at a radiation detector.

Abstract: A device and method for the radioscopic examination of a continuous strip-shaped material of rubber which runs continuously in particular. During the movement, the strip-shaped material is x-rayed by a radioscopic measurer and the entire cross-sectional surface is detected so that foreign bodies or defects present in the material are detected according to their position and orientation. An elimination device removes the previously identified foreign body during the feed movement of the material in that a tool, configured as a punching tool, of the elimination device is moved synchronously with the material.

Abstract: Nuclear-based basis weight sensors are passline-sensitive. Error in measurement is induced when the sheet moves up and down in the gap between the radiation source and detector. A passline-insensitive basis weight sensor includes a triangulation sensor to measure the position of the sheet within the gap. The sensor and gap is characterized in the laboratory for its passline behavior over a range of basis weights. The curves are either parameterized or a lookup table is created for each weight and passline position and the data added to the sensor's processor. The basis weight measured can be automatically corrected to account for deviations from the passline or nominal path through the sensor.

Abstract: A method of determining the density profile of a plate-shaped material M, the density of which varies discretely or continuously across the plate thickness, whereas the density at a specific depth of the plate M is preferably assumed to be constant. The inventive method employs X-rays or .gamma.-rays from a source K. The latter source K is placed on one side of the plate M, whereas at least two detectors T, F are arranged on the opposite side of the endless plate being advanced during the measuring in the longitudinal direction. A first detector T is preferably placed in the radiating direction of the source and measures the transmittent radiation through the plate M, and the second detector F is placed outside the radiating direction of the source K and measures the scattered radiation on partial volumes along the radiating direction of the source. Based on the signals measured by the detectors it is possible to measure the density in each individual partial volume. According to the invention a compensation has furthermore been carried out for multiple scattered radiation by the measured radiation being deducted from the multiple scattered radiation.

Abstract: A nuclear gauge (7) for making measurements of traveling webs (11) in continuous sheet-making processes includes an enclosure (20), an encapsulated nuclear source (28), and a wheel-like member (10) mounted in the enclosure means for carrying the encapsulated nuclear source between two angularly-displaced positions. The first of the angularly-displaced positions is the position whereat the encapsulated nuclear source makes measurements of a web that travels past the gauge, and the second position is the location whereat the encapsulated nuclear source faces a sidewall of the enclosure means at a location remote from the first position. The nuclear gauge also has an aperture (16) which is formed through the enclosure for providing a window through which the encapsuled nuclear source, when located in the first position, can emit radiation onto a web that travels past the window.
