Abstract: L'invention a pour objet une méthode pour le nettoyage d'une fosse septique du type comportant au moins deux cuves de fermentation-décantation raccordées entreelles par un conduit latéral, chacune des cuves contenant un milieu bactériologique et des boues déposées et consolidées ou non sur leurs fonds, la première de ces cuves contenant en outre une phase d'huiles, graisses et/ou solides légers flottant à la surface dudit milieu bactériologique. Cette méthode est caractérisée en ce que dans une première étape, on pompe la phase d'huiles, graisses et/ou solides légers flottant à la surface de la première cuve vers un réservoir de vidange puis pompe, à basse vitesse, le milieu bactériologique contenu dans chacune des cuves vers un réservoir de stockage. Alternativement, on peut pomper à basse vitesse, le milieu bactériologique contenu dans la dernière cuve vers un réservoir de stockage, le pompage dudit milieu étant stoppé lorsque la phase d'huiles, graisses et/ou solides légers s'engage dans le conduit latéral raccordant les cuves entre-elles. Dans une deuxième étape, on pompe les boues et les éventuels huiles, graisses et solides légers se trouvant dans le fond des cuves vers le réservoir de vidange, après avoir préalablement remanié ces boues, huiles ou solides sous une forme semi-liquide par injection d'eau sous haute pression et à faible débit ou les avoir liquifiés par action d'un élément vibrateur. Enfin dans une troisième étape, on réintroduit le milieu bactériologique stocké dans le réservoir de stockage, dans les cuves de la fosse nettoyée. Cette méthode présente l'avantage de conserver intact le milieu bactériologique des fosses septiques et de diminuer le volume des déchets retirés desdites fosses. L'invention concerne également une citerne spécialement adaptée pour mettre en oeuvre la méthode ci-dessus mentionnée.

Abstract: MACHINE FOR MANUFACTURING FOAM BUILDING BLOCKS                 Astract of the Disclosure A machine for manufacturing foam building blocks (39) and the like wherein a plurality of two-piece forming molds (21) are continuously moved by a conveyor mechanism along a closed path- of-travel (22) is disclosed. Filling, curing and injection stations (31, 32 and 33) are located along the path-of-travel (22). As a mold (21) enters the filling station (31), the nozzle (37) of a foam gun (35) enters a hole (34) in the top of the mold (21) and moves with the mold (21) as that mold continues to move along the path-of-travel (22). At the end of the filling station (31), after the foam gun (35) has injected a suitable amount of resin, curing and foaming agent materials into the mold (21), the nozzle (37) rises from the hole (34). Thereafter, a cap-latch (36) is moved into a hole closed position. In addition to closing the hole (34), the cap-latch (36) forms one of two latches that latch the two mold pieces (21a and 21b) together. The other latch (38) is located on the opposite side of the forming molds (21). After leaving the filling station (31), the forming molds pass through the curing station (32) where they are heated to a suitable temperature. After leaving the curing station (32), the forming molds (21) enter the ejection station (33) where the latches (36, 38) are opened, the forming mold pieces (21a and 21b) are split apart and the finished foam block (39) is ejected. Then, the forming mold pieces (21a and 21b)are brought back together and the latch (38) is closed. Thereafter, the forming molds (21) are moved to the filling station (31) and the cycle is repeated.

Abstract: PROCESS AND APPARATUS FOR HANDLING WASTE FROM                OIL WELL OPERATIONS                                      ABSTRACT   A process and apparatus are disclosed for separating drilling mud and waste materials into pure water and a concentrated solid waste phase which is easily handled and disposed of. The process and apparatus provide for adjusting the pH of the drilling mud and waste materials to be separated, mixing the thus pH adjusted mud and waste materials with a flocculating agent and allowing the solids to settle out. The solids are then removed and further dewatered to produce a relatively dry concentrated solid waste phase. If desired, the clarified water is mixed with finely divided activated charcoal to remove various impurities from the clarified water. The mixture of clarified water and charcoal are then filtered to produce a filtrate stream which is further separated to produce pure water and a liquid phase containing dissolved solids. The pure water can then be reused in the drilling process or safely discarged into the environment.

Abstract: ADAPTIVE CONTROLLER FOR ELECTRIC POWER STEERING            Abstract of the Disclosure A torque transducer senses the operator exerted steering torque and provides an output signal which varies in magnitude from a low value representative of a large operator exerted steering torque in one direction through a mean value repre-sentative of no operator exerted steering torque to an upper limit value representative of a large operator exerted steering torque in the opposite direction.  The controller develops a zero torque reference which has an initial value substantially corresponding to the mean value of the torque transducer output signal, and steering torque assist is developed in relation to the difference between the zero torque reference and the trans-ducer output signal.  In operation, the zero torque reference is shifted according to a predetermined time response characteristic in a direction to reduce the difference between it and the transducer output signal.  Over a period of time, the shifting of the zero torque difference due to operator exerted steering torque tends to cancel out and the remaining shifting adaptively compensates the zero torque reference for drift and other like sources of error affecting the magnitude of the transducer output signal.

Abstract: ABSTRACT OF THE DISCLOSURE                    METHOD FOR DESALTING CRUDE OIL      The salt content of crude oil is reduced by washing crude oil containing residual salt water with wash water of lower salinity than the water present in the crude oil and allowing the resulting mixture to settle into a layer of crude oil of reduced salt water content and a layer of saline water.  The quantity of wash water employed is greater than 7.5% by volume of the crude oil.    The saline water may be recycled and a proportion removed from the recycle stream and a corresponding quantity of water of lower salinity added.     Washing with relatively large quantities of water results in the formation of a less stable emulsion.  Consequently, less severe conditions are required to break it to recover the desalted crude oil.

Abstract: ABSTRACT OF THE DISCLOSURE            "A METHOD OF AND DEVICE FOR CODING WORKPIECE CARRIERS                   IN A PRODUCTION PLANT"     Workpiece carriers are fed to successive work stations along conveyor tracks at which stations work operations are performed on individual parts on the carrier and in which a defect signal is allocated when appropriate.  After a work operation has been performed a coding member is left in a normal switching position corresponding to a defect coding or displaced into a switching position corresponding to an accept coding if the work operations performed were satisfactory.   In a coding device displaceable coding elements are supported by a workpiece carrier and traverse a detector device at the work processing station and a switching element for displacing the coding element from a reject coding switch position to an accept coding switch position.     Advantageously an accept coding is only secured by a deliberate action when satisfactory work processing has been completed and thus subsequent processing of defective parts is avoided simply and with great reliability.

Abstract: FIBER OPTIC CONNECTOR Abstract Disclosed is an electro-optical component package, arranged as a dual in-line pin (DIP) package, and a socket therefor.  Connector pins extending from the package establish electrical and optical contact to the package with mating connector receptacles of the socket. Each pin and receptacle has a metallic body for establishing electrical connection between the pin and receptacle when the two are mated.  Each body defines a passageway through which extends an optical fiber .   When the bodies of a pin and receptacle are mated, the optical fibers extending therethrough are optically coupled.  The receptacle includes a cup member that is positioned loosely and movably in its passageway.  The cup member defines a passageway by which it mounts around the end of the receptacle's fiber.  When the pin and receptacle are mated, the cup member receives and mates the end portion of the pin, thereby aligning the ends of the receptacle's and pin's fibers.  A coiled spring positioned in the receptacle's passageway around the receptacle's fiber urges the cup member against the end portion of the pin.
