IPC: B22D11/06
Filed: 1983-04-26
Granted: 1987-01-28
Abstract: Methods and apparatus for feeding and continuously casting molten metal (1) are described in which inert gas is applied to the moving mold surfaces and to the entering metal for the protection or shrouding of the molten metal surface within the mold cavity from oxygen and other detrimental atmospheric gases. The shrouding is by means of inert gas injected into the mold through a semi-sealing nosepiece (7), or directed at the mold cavity and passing through the necessary slight gaps around the nosepiece. At the same time, such inert gas is further circulated by channeling or shielding the circulated gas for blanketing and diffusing of the inert gas along the moving mold surfaces (9, 10) for cleansing them of undesired accompanying gases, such as atmospheric oxygen, water vapor, sulphur dioxide, carbonic acid gas, etc. as the mold surfaces approach the nosepiece before entering the mold region. In installations where the inert gas is directed at the mold cavity from above and/or below the nosepiece, the gas is ejected at a relatively slow flow rate so as to be noiselessly ejected, i.e. without audible disturbance, the objective being to avoid entrainment of air. Heavier-than-air inert gas may advantageously be used above the nosepiece, while lighter-than-air inert gas is simultaneously used below it.

Granted: 1989-01-11
Abstract: Cet appareil de production d'azote gazeux de grande pureté peut être utilisé dans des domaines tels que, par exemple, l'industrie électronique, pour la fabrication de semiconducteurs au silicium. Les appareil cryogènes conventionnels de liquéfaction et de production d'azote gazeux PSA présentent de nombreuses défaillances, et l'azote obtenu par ces appareils conventionnels a un prix élevé, tout en étant d'une pureté médiocre. Dans l'appareil de la présente invention, une tour de fractionnement (15) est reliée à un réservoir de stockage d'azote liquide (23) par l'intermédiaire d'un chemin d'admission (24). De l'air comprimé à une température ultra-basse, qui est pompé dans la tour de fractionnement (15) au travers d'un compresseur d'air (9), d'un organe d'élimination (12) et d'échangeurs thermiques (13), (14), est refroidi encore plus par la chaleur d'évaporation de l'azote liquide, de sorte que l'azote peut être extrait à l'état gazeux, en laissant l'oxygène à l'état liquide, à cause de la différence entre leurs points d'ébullition respectifs. L'azote ainsi obtenu est mélangé à de l'azote liquide pulvérisé provenant du réservoir de stockage d'azote liquide (23), de manière à obtenir l'azote final à l'état gazeux. Il est ainsi possible de produire de l'azote gazeux d'une grande pureté d'une manière économique, pratiquement sans défaillances mécaniques.

Abstract: An image generator for generating two-dimensional images of three-dimensional solid objects at a high speed defines a scene to be displayed within a cuboid three-dimensional universe which has been hierarchically subdivided into a plurality of discrete volumes of uniform size and similar orientation. The three-dimensional universe is represented by a tree structure having a plurality of nodes, one for each volume in the three-dimensional universe which is at least partially occupied by objects in the scene. A user may select a point of view for viewing the object. Nodes in the tree structure representing the three-dimensional universe are visited in a sequence determined by the point of view selected by the user so that nodes corresponding to volumes which are unobstructed by other volumes are visited first. Each visited node which is enclosed by the object is projected onto a subdivided view plane organized into a hierarchy of a plurality of discrete areas. Areas of the view plane which are completely enclosed by the projection are painted onto a display screen. Areas which intersect but are not enclosed by the projection are further subdivided to locate those areas which are enclosed. A representation of the hierarchically-subdivided view plane arranged in a tree structure is stored in a store. Each time an area of the view plane is painted, an entry in the representation of the view plane corresponding to that area is marked. The corresponding entry in the representation of the view plane is checked before an area is painted, to ensure that no area is painted more than once so that hidden surfaces are not displayed. To create sectional views, a user may define a region of the three-dimensional universe, and volumes outside of that region are not projected. Due to the hierarchical structure of the three-dimensional universe and the two-dimensional view plane, the symmetry of subdivisions, and the resulting simplicity of the calculations necessary to create an image, real time image generation wherein calculations necessary to create the image are performed by hard-wired digital logic elements to increase speed performance is possible.

Abstract: A cloudy liquid to be clarified is inserted, after twice receiving flocculation additive, into the bottom of a belt of sludge (4a) in a clarification chamber (4) via a plurality of injectors (22) distributed over the area of said chamber. Uniform distribution of overall flow between these injectors is ensured by internal head loss. The clarified liquid is removed via an upper overflow (4b). Each injector is constituted by a flat cyclone and forms a jet which is highly diverting from its vertical axis in such a manner that the injected flowrate spreads out over an expansion zone belonging to said injector and meeting the expansion zones of adjacent injectors. Further, these jets set up swirling motion which prevents the formation of a layer of sludge having insufficient permeability. The sludge formed in the chamber (4) is directed via a central well (7) towards a secondary clarification sludge (3) situated beneath said chamber and supplying both clarified liquid and dense sludge.
