Abstract: An apparatus for removing solids from flowing liquids has a screw conveyor (2, 3, 3a), which rotates freely on the inlet side in a tube (1) having through-holes (1a). This enables, for example when the apparatus is installed at an angle, the unhindered entry of a dirt load (S), its dewatering, compression and transport away. A method of operation is based on monitoring the level at the inlet of the tube (1) for a maximum (N') and, when this is reached, turning on the drive (7, 7a) of the screw conveyor (2, 3, 3a) and, after the level falls, that is after the removal of the dirt portions (S, S'), the drive continuing to run for a further delay time and cleaning the tube (1). A preferred application of the subject-matter of the invention is its use in the inlet channel (11) of a sewage treatment plant for mechanical purification of the sewage. <IMAGE>

Abstract: In a fuel bundle (B) for a boiling water reactor having one or more part length rods (22) in the two phase region, a steam vent tube (T1) is introduced overlying the part length rods (22). This steam vent tube has openings (44,46) and devices distributed along its length to encourage steam flow interior of the tube and remove liquid flow from the interior of the tube. The steam flow within the vent tube (T1) eliminates the interface drag between the steam interior of the tube and the surrounding water steam mixture. The presence of the steam vent tube as a high velocity steam escape path enables remaining portions of the fuel bundle to contain a higher liquid moderator fraction with flatter axial voids and power distributions during the operating state of the fuel bundle. The presence of high velocity escaping steam combined with distributed apertures along the length of the steam vent tube promotes resistance to fluid oscillations within the fuel bundles. Variations of the steam vent tubes are disclosed including steam vent tubes overlying multible clustered part lenght rods. There results a fuel bundle design in which the entire upper cross section of the fuel bundle is devoted to steam generation and coolant outflow.

Abstract: A temperature sensor has a flexible nylon tube (6) connected by a fluid-tight coupling (30,40,50) to a metal bellows (19) within a metal housing. The interior of the tube (6) and bellows (19) is filled with a pressurised liquid whose critical temperature corresponds to a threshold temperature to be sensed. The pressurised liquid holds the bellows (19) extended, holding an actuating piston (17) back against the action of a spring (21). When the threshold temperature is reached, the liquid in the tube (6) must boil and ruptures the tube, causing the bellows to collapse and the actuating piston (17) to move. A projecting actuator (11) then mechanically initiates a response such as the closing of a damper in an air-conditioning duct.

Abstract: The method consists in:   extracting (10), from a picture shot, two images (1, 2) of an illuminated scene containing foreground areas and background areas, the depth of field seen by the picture-taking device being greater for the first image (1) than for the second image (2), extracting (16), from each image, high-frequency components (165) characteristic of the sharpness of the images, so as to obtain two high-frequency signals, comparing (166) the two high-frequency signals to obtain, by differencing, a depth signal.   This method thus makes it possible to decide whether a point of the image belongs to the foreground or to the background and hence avoids the use of a background of uniform colour in special effects devices working in accordance with the "chromakey" technique. <IMAGE>

Title: Injection molding apparatus and process.
Inventor: GIANNI RICHARD F
IPC: B29C48/48
Filed: 1991-10-29
Abstract: Foam thermoplastic injection molding apparatus and method produces structurally superior foam injection molded products. The process includes plasticating solid polymer to a polymer melt; accumulating the melt in an accumulator having a telescoping inlet, which allows the first melt which enters to be the first to leave the accumulator; combining a preselected amount of melt with a preselected amount of gas in bubble form to form homogenized polymer foam; shearing the homogenized polymer foam to reduce the size of gas bubbles; and injecting the polymer foam through a special gate assembly into a mold. The gate assembly has a removable nose which remains with the mold, allowing the foam to expand within the mold but not allowing the foam to escape the mold. The process and apparatus allow low molded-in stress products to be produced, and can process recyclable thermoplastics, either single materials or mixtures. Thus, no segregation of materials is required.

Abstract: Dans un appareil de traitement photographique, il est nécessaire de régénérer les solutions de traitement au fur et à mesure de leur épuisement. La technique connue consiste à régénérer les produits chimiques dans un processeur de papier en déterminant la quantité d'exposition que subit le papier pendant l'étape d'impression de l'appareil, lors de la copie sur papier photographique d'une image sur une bande de pellicule, et en utilisant cette valeur pour calculer la quantité d'agent de régénération requis pour compenser exactement les produits chimiques épuisés lors du traitement de ladite image. On décrit un procédé d'utilisation des données relatives au facteur de transmission optique mesuré d'une image sur une bande de pellicule pendant l'étape d'impression pour réguler aussi bien la régénération des solutions de traitement pendant l'étape de traitement de la pellicule dans l'appareil, que l'élimination de produits dérivés dépendants de l'image formés pendant le traitement de ladite bande de pellicule.
