Abstract: Disclosed techniques relate to ray intersection processing for ray tracing. In some embodiments, ray intersection circuitry traverses a spatially organized acceleration data structure and includes bounding region circuitry configured to test, in parallel, whether a ray intersects multiple different bounding regions indicated by a node of the data structure. Shader circuitry may execute a ray intersect instruction to invoke traversal by the ray intersect circuitry and the traversal may generate intersection results. The shader circuitry may shade intersected primitives based on the intersection results. Disclosed techniques that share processing between intersection circuitry and shader processors may improve performance, reduce power consumption, or both, relative to traditional techniques.

Abstract: Ferromagnetic workpieces such as steel bars are tested for cracks or inclusions by means of the magnetic powder method with the additional application of a visual check by means of a flying light spot. The magnetic powder contains a fluorescent dye additive which, when scanned with the flying light spot, emits a fluorescent light which is received by a photoelectric transducer, transformed into pulses and supplied to an evaluating stage. The flying light spot is generated as an ellipsoidally extended light spot which, referred to its ellipse axis, is conducted at a constant angle over the workpiece to be tested. This angle is set to a different value in a dark phase before each scanning cycle, each area of the workpiece being scanned once in each angular position. The analog signals emitted by the photoelectric transducer are mathematically investigated in the evaluating stage, digitised, entered in a memory and evaluated. <IMAGE>

Abstract: A process of producing a fibre-reinforced composition comprising drawing a plurality of continuous filaments through a melt comprising a mixture of a thermoplastic polymer and a plasticiser for the polymer in the weight ratio between 1:4 and 99:1 of polymer to plasticiser, preferably in the weight ratio 1:1 to 19:1, the plasticiser being thermally stable at least up to the temperature of the melt and having volatility characteristics such that the plasticiser is not substantially volatilised from the composition below the melt temperature of the thermoplastic polymer but has a sufficiently low volatility at the temperature of the melt to plasticise the polymer in the melt and give a melt of reduced viscosity compared with the melt viscosity of the polymer alone. The process enables improved fibre wetting and/or easier processing to be achieved in comparison with a process in which no plasticiser is used. Higher molecular weight polymer may also be used than when plasticiser is absent.

Abstract: X-ray apparatus for tomography and other procedures. For tomography, a column is translated longitudinally parallel to the patient supporting table top. An x-ray tube is supported on the column above the table top for angulating about a laterally extending axis at a constant elevation on the column. A bucky carriage for containing a film is mounted under the top for moving longitudinally. A fulcrum arm is pivotally connected at one end directly to the bucky carriage for pivoting on a laterally extending axis lying on the film plane. The other or upper end of the arm is connected to the x-ray tube for angulating it so the central ray of the x-ray beam is always directed to the center of the film during column translation. The upper end of the fulcrum arm is slidable relative to the x-ray tube angulation axis. An extensible and contractible link means below the bucky carriage pivotally connects at its upper end to the carriage and at its lower end to the column for swinging about a lateral axis that is vertically aligned with the x-ray tube axis. The link means pivots about a lateral axis on a support member whose elevation is adjustable relative to the film plane. The elevation of the link means pivot determines the height above the table top of a fixed vertical axis about which the fulcrum arm swings and, hence, it determines the height of the plane in a body lying on the table top that will be imaged without blurring on the film.
