摘要： Apparatus for measurement of the stress birefringence of an optical sensor that is influenced by a quantity to be measured. An optical emitting device sends light of two adjacent wavelengths .lambda..sub.1 and .lambda..sub.2 through an emitting light guide and via a polariser and a retarder plate to the sensor. An analyser conducts mutually parallel polarization components of the light emerging from the sensor on a common path to a receiving and evaluating device which derives from the measured-value-dependent intensities of such polarization components information concerning the magnitude of the quantity to be measured. The thickness of the retarder plate is dimensioned to provide a path length w of the light through the retarder plate such that the two light components .lambda..sub.1 and .lambda..sub.2 that leave the analyzer are influenced in mutually opposite senses by the measured quantity via the sensor, so that they do not need to be separated by optical filters and combined again by a coupler.

摘要： The yarn tension at each of a plurality of yarn processing stations is continuously monitored, while continuously determining the mean value of the monitored tension at each station, and while also continuously determining the differential between the monitored value and the mean value. Also, an alarm signal is generated whenever the mean value leaves a predetermined tolerance range, and whenever the differential value leaves a second predetermined tolerance range. An alarm signal may serve to actuate a visual error indicator, or to shut down the associated processing station.

摘要： An inductively heated godet is mounted on a supporting frame which carries a rotatable drive shaft. A stationary primary winding is mounted about a magnetic core carried by a body which is fastened to the frame. A rotatable hollow shell which concentrically surrounds the primary winding is removably secured to the rotatable drive shaft.The magnetic core and rotatable hollow shell have in their longitudinal section essentially opposing L-shaped profiles with the flank portions thereof being concentric to the godet turning axis and the foot portion of each L-shaped profile extending substantially radially with respect to the godet turning axis toward the opposing flank portion of the other L-shaped profile such that the flank and foot portions of the shell and magnetic core form radially spaced annular gaps therebetween which are concentric to the godet turning axis. In addition, the axially directed gaps necessarily formed between the magnetic core and rotatable hollow shell are relatively large with respect to the annular gaps so that magnetic flux created by the primary winding will flow almost entirely over the smaller annular gaps. In one embodiment, the foot portion of the L-shaped profile of the shell has a recess formed therein which may be filled with an electrically conductive material which helps direct the magnetic flux and increase the heating effect in that zone of the shell. In another embodiment, the primary winding is formed of multiple electrically interconnected partial coils which are slidable on to the magnetic core.

摘要： The invention relates to a detection values processing apparatus. Energy-dependent detection values are provided, which are indicative of polychromatic radiation (4) after having traversed an examination zone (5). The radiation is filtered by a filter (15) which comprises K-edge filter material. A component decomposition technique is applied to the detection values for determining K-edge attenuation values being first component attenuation values, which are indicative of an attenuation caused by the K-edge filter material, and additional component attenuation values, which are indicative of an attenuation caused by additional components of the examination zone, wherein an image of the examination zone is reconstructed from the additional component attenuation values. An image can therefore be reconstructed, which is not adversely affected by the filter, because the K-edge attenuation values are not used for reconstructing the image. This can improve the quality of the reconstructed image.

摘要： The invention relates to a method and a device for determining the distribution of an X-ray fluorescence (XRF) marker (16) in a body volume (14). The body volume (14) is irradiated with a beam of rays (12) from an X-ray source (10) with a first ray component with a quantum energy just above and a second ray component with a quantum energy just below the K-edge of the XRF marker (16). Secondary radiation emitted from the body volume (14) is detected in a location-resolved way by a detector (30). To separate the X-ray fluorescence components in the secondary radiation from background radiation, the body volume is irradiated for a second time with a beam of rays from which the first ray component has been substantially removed by a filter (22) made from the material of the XRF marker.

摘要： An X-ray apparatus comprises a polychromatic X-ray source for generating a primary beam of small cross-section, an energy-sensitive detector arrangement for detecting the scattered radiation produced by elastic scattering processes in the primary beam, which detector arrangement comprises a plurality of detector elements which are arranged on rings concentric with the primary beam, and a collimator arrangement which is arranged between the X-ray source and the detector arrangement and which encloses the primary beam. In order to enable accurate determination of the pulse transfer spectrum while using a low dose, the collimator arrangement is constructed so that the scattered radiation from the same section of the primary beam is incident on a plurality of detector elements.

摘要： An optical sensor (1) is connected to an electro-optical transducer unit (35) and a measuring circuit (36) via an optical delay line (14) and an optical path (15). Error-free measurement values which are independent of the attenuation characteristics of the optical delay line (14) are obtained if the optical sensor (1) comprises a polarization splitter (3) which receives light pulses from the optical path (15) and from the optical delay line (14) and which is followed by a sensor body (2) which is traversed by the light pulses. A mirror (4) arranged on the side of the sensor body (2) on which the light is not incident reflects the light pulses back into the polarization splitter (3), which couples the light pulses back into the optical path (15) and the optical delay line (14).

摘要： A method and apparatus to centrally collect measured values of a variable parameter from each of a plurality of work stations, and so as to facilitate quality control. Each work stations includes a sensor for generating an output signal which is a function of the variable parameter, and the output signal is converted to digital signals, which represent discrete increments within the measuring range of the variable parameter. The digital signals are stored during a predetermined period of time in a memory unit so as to be available for periodic scanning by the central computer, after which the stored signals are cleared so that the memory unit is free to record the values during the next period of time. Also, circuitry is provided whereby only the extreme values of the output signalsd ar stored, together with the mean value, which are adequate to provide a complete statement of the quality of the process and product being monitored.
