摘要： To determine the thickness profile of rolled metal sheets by measuring the absorption of X-rays a slit diaphragm is used which is rotatable about the imaginary center axis of the X-ray tube, the rotation consisting of a reciprocating movement lying in a range of less than 36.degree.. Between the reversal points of the rotation the rotational movement takes place in steps with rest intervals lying therebetween.

摘要： A tubular part wall thickness measuring device includes a radiation source having a plurality of radiation sources disposed in a line. The radiation passes through a collimator to provide parallel radiation beams which pass transversely through a tubular part to a radiation detector. The length of the radiation source and the radiation detector are greater than the diameter of the tubular part to be measured so that the radiation passes through an entire section of the tubular part so that the average wall thickness of the tubular part can be determined from the amount of attenuation of radiation which is detected by the detector.

摘要： The invention relates to a non-destructive, dimensional control process and apparatus with respect to a hollow member.The apparatus comprises means making it possible to hold and position the member, a source which can be introduced into the member so as to emit gamma radiation in the direction of the inner surface of the wall of said member. A detector can be positioned outside the member, so as to detect the gamma radiation traversing the wall of said member. In addition, means are provided making it possible to effect a relative displacement between the assembly, constituted by the source and the detector, and the member in such a way that the wall profile of the latter is followed.

摘要： A method of steering a mineral mining machine so as to remain in the mineral seam. Natural radiation from rock strata adjacent to the mineral seam is sensed and the machine is steered from the intensity of radiation so that a residual layer of mineral left by the machine which attenuates the radiation has a thickness which is constrained to fall within preselected limits.

摘要： A method is disclosed for detecting the formation of or presence of light-interacting domains, e.g. particles or clumps of particles, in a supporting medium which comprises: disposing the supporting medium between a source of multipoint ilumination and a scintillation detector, illuminating the supporting medium with a multiplicity of discrete light beams directed through the medium toward the scintillation detector; and causing relative motion between the light beams and the supporting medium. If light-interacting domains of critical size are present in the medium scintillation is detected. A viewer and test card for carrying out the method are also disclosed.

摘要： Disclosed are a system for and method of dividing or partitioning the total variance properties of a moving sheet into the components of: cross direction; long-term machine direction; short-term machine direction; total machine direction; cross direction; and profile. A single detector for the property is scanned at right angles to the sheet edges a plurality of times. During each scan the property is sampled a plurality of times to derive a profile contour. A computer responds to the sampled values to derive the variance components.
