Abstract: La section transversale d'un collecteur d'energie solaire presente le profil d'un ensemble de cuves emboitees, tronquees et renversees formant une rangee (12) de troncs de cones annulaires concentriques. La rangee s'eleve depuis une base, definie par le tronc le plus a l'exterieur, jusqu'a un sommet defini par le tronc le plus a l'interieur. Le collecteur est dispose entre le soleil et un absorbeur (42) d'energie solaire. Le collecteur est connecte a un dispositif (26) d'alignement avec le soleil permettant un mouvement dans une direction predeterminee et sur une distance predeterminee relative au centre de l'absorbeur eloigne. Les troncs de cones (12) possedent des surfaces interieures reflectrices, dont chacune est definie par une parabole singuliere et unique. La lumiere incidente sur les surfaces est transmise par une seule reflexion au travers des ouvertures a la base de la cuve, sur un point de focalisation commun situe sur l'absorbeur (42) pour une concentration optimale de la radiation captee qui peut etre utilisee sous forme d'energie thermique ou etre convertie en d'autres formes utiles d'energie.

Abstract: n an automatic chemical analyzer, a plurality of reaction tubes (8) are arranged at regular intervals on a circular line along the peripheral edge of a discoid reaction tube holder (5). The lower-half portions of the reaction tubes are immersed in water in a thermostatic bath (1) kept at a fixed temperature. One or more reagents and samples are contained in the reaction tubes. A suction body (9) and a sampling body (10) are supported for vertical motion, extending parallel to each other right over the circular line. Plunger pumps (21a), (25a) are coupled to the suction and sampling bodies. An absorbancy measuring device (17, 18, 19) is interposed between the suction body (9) and its corresponding plunger pump (21a). The reagent is sucked through a sampling nozzle (10a) at the lower end of the sampling body (10) by its correspoding plunger pump (25a), and is dispensed by a given amount at a time to the samples in the reaction tubes through the sampling nozzle as the reaction tube holder rotates. After biochemical reactions between the samples and the reagent are ended or in the middle of the reactions, reaction mixtures are sucked through a suction nozzle (9a) at the lower end of the suction body (9) by its corresponding plunger pump (21a), and are supplied to the absorbancy measuring device for measurement of the quantity of light transmitted through the reaction mixtures.

Abstract: A foamable ink composition which comprises a water-based printing ink, a foaming agent and a pseudoplastic additive. The ink, foaming agent and pseudoplastic additive are foamed with a compressed gas. The pseudoplastic additive aids in the mixing of the ink with the gas and enhances the stability of the foam. Th foam is especially adapted for application to a gravure cylinder where it is doctored to convert the foam bubbles into thin discrete membranes spanning the gravure cells. These membranes then are transferred, either directly or indirectly to a moving web.

Abstract: Equipement convolutionneur micrologique destiné essentiellement à effectuer la phase de filtration unidimensionnelle discrète de l'algorithme à rétroprojection filtrée appliqué dans des systèmes tomographiques commandés par ordinateur. La convolution est effectuée dans le domaine spatial sur la base d'une convolution par projection. Le convolutionneur est en interface d'une part avec le canal DMA d'un mini ordinateur, et d'autre part il est connecté à un rétroprojecteur pouvant fonctionner avec le convolutionneur suivant un mode en pipeline. Pour utiliser de manière efficace le système ordinateur-convolutionneur-rétroprojecteur, l'équipement est d'une conception du type pipeline. Le convolutionneur est supporté par un interpolateur produisant une sortie directement applicable pour une rétroprojection basée sur une interpolation linéaire. La simplicité de l'équipement est obtenue grâce à des circuits logiques d'adressage (4, 31, 40) conçus sur le principe de la convolution discrète.

Abstract: Swingable front and back plates (72, 74) are supported by a hinge. Cushion members (84,86) are pasted individually on the inner surfaces of the front and back plates (72,74). The cushion members (84,86) individually have two-dimensional curved surfaces with the same radius of curvature, and are arranged so that the directions of curvature of their curved surfaces cross substantially at right angles. Intensifying screens (92, 94) curved to match the surfaces of the cushion members are pasted thereon. An X-ray film is sandwiched between the intensifying screens (92, 94), and the front and back plates (72, 74) are joined together. Thereupon, the region of each cushion member (84, 86), pressing the X-ray film through its corresponding intensifying screens (92, 94), extends gradually, moving its center from the hinge side to the free-end side. When the front and-back plates (72, 74) are joined together, the X-ray film recieves a-maximum pressing force from the center of each cushion member (84, 86). The pressing force decreases with radial distance from the center.
