Abstract: An X-ray CT examination installation, having an X-ray tube including a focus, that creates a fan beam or a conical beam which X-rays the whole of a detector at a fixed distance from the focus, and an examination carriage, for supporting an object to be examined, the carriage having an axis of rotation perpendicular to the fan beam, wherein the examination carriage can be fixed inside the fan beam close to an edge axis which meets the detector at the edge, and can be moved on a measuring line that centrally runs at an angle to a central axis which meets the detector. The invention also relates to a CT method of examining objects, in particular of various sizes, by means of an X-ray CT examination installation generally identified above.

Abstract: A method for automatic defect recognition in testpieces by means of an X-ray examination unit having a mechanical manipulator for positioning the testpiece in a beam path of the X-ray examination unit, wherein a positioning image of the testpiece is compared with an ideal reference image. An axis of rotation, an angle of rotation and a displacement vector are calculated in order to arrive at an exact congruence of the positioning image of the testpiece with the ideal reference image. The values of the axis of rotation, angle of rotation and displacement vector are then relayed to the mechanical manipulator and the latter then transfers the testpiece into the position corresponding to these values.

Abstract: The invention relates to a clamping device for power cables with an essentially tubular bell housing in which a tubular holding element for a power cable is arranged mobile along the central longitudinal axis of the bell housing, and with a spring which is arranged between a stop in the bell housing and the holding element and pushes the holding element away from the stop along the central longitudinal axis, a display element being arranged at the holding element, so that the tension of the spring can be learned from outside, and the spring surrounds the power cable.

Abstract: The invention relates to an X-ray CT examination installation, with an X-ray tube with a focus, which creates a fan beam or a conical beam which X-rays the whole of a detector located at a defined distance from the focus, and with an examination carriage, for receiving an object to be examined, which has an axis of rotation rotatable perpendicular to the plane of the fan beam or to the central axis of the conical beam. It is provided according to the invention that the examination carriage can be fixed on at least one measuring point, wherein each of these measuring points is arranged such that the axis of rotation is on a measuring line which emanates from the focus and includes a tilt angle ? with the central axis of the fan beam or the conical beam. The invention also relates to a CT method of examining objects, in particular of different sizes, by means of an X-ray CT examination installation according to the invention.

Abstract: A baggage inspection device based on coherent x-ray scatter has an x-ray source on one side of the scanning area and detectors on the other side of the scanning area. The detectors measure the energy of the scattered x-ray quanta. A primary ray collimator is arranged between scanning area and x-ray source. A secondary ray collimator for scattered rays is arranged between scanning area and detectors. The detectors are positioned on a Z axis forming an axis of symmetry for the secondary ray collimator. A point 0 on the Z axis forms the origin of a Cartesian coordinate system. The primary ray collimator allows passage only of x-ray beams impinging on the point 0. The x-ray source has an extended anode with a focus position controlled electronically about the anode length. Primary ray collimator and x-ray source extend cylindrically symmetrically about the symmetry axis or parallel to the Y axis in the X-Y plane.

Abstract: The present invention relates to a method and an apparatus for the testing or inspection of objects, particularly for detecting defects or irregularities therein, by means of X-radiation, where the object to be inspected is brought into different spatial positions and stays there during image detection. For mechanical positioning of the objects, known methods and apparatuses require a relatively long time with limited inspection precision, while having a considerable space requirement. Accompanied by a small size, the invention obviates this problem in that the X-ray components, comprising X-ray tube and X-ray detector, are only moved in translatory manner and the inspection object or part in a gimbal suspension is only moved in rotary manner in at least one axis and a maximum of three axes x, y and z.

Abstract: An apparatus for measuring the pulse transmission spectrum of elastically scattered quantities includes at least one diaphragm displaceable in a y-direction for switching between fine and coarse local resolution of the examined partial volumes of an examination object, wherein the diaphragm narrows the effective ray width transversely of a scanning direction, and a diaphragm system displaceable in a x-direction for limiting and extension of the partial volume in a z-direction, wherein the diaphragm system includes at least two circular ring diaphragms arranged one above the other and identical with respect to their circular ring structure, and wherein the circular ring diaphragms are arranged at a relative offset for reducing an effective imaging slot width or a detector slot width.

Abstract: A method and an apparatus for examining luggage by X-ray scanning, wherein the pieces of luggage to be examined are moved on a conveyor belt into a scanner which contains the X-ray components, i.e., an X-ray unit and a detector unit. The scanner together with the X-ray unit and the detector unit is moved over the piece of luggage which stands still. After each scanning process, the piece of luggage is moved on the conveyor belt in a timed manner and the step of scanning the piece of luggage is repeated.
