Title: Systeme de commande sensible au minimum aux forces hydrostatiques d'une ligne de commande
Inventor: ANDERSON DAVID Z
IPC: E21B34/10
Filed: 2007-11-13
Granted: 2012-10-23
Abstract: Un système de commande d'un outil de fond de trou, tel qu'une vanne de sécurité de subsurface, comprend un piston moteur qui est insensible à la pression des tiges de production dans la vanne. Les forces hydrostatiques provenant de la ligne de commande unique de la surface sont considérablement réduites avec une ligne en dérivation vers un fond de piston de taille légèrement inférieure à la tête de piston. Un volume variable entre les joints de piston est relié à un réservoir de fluide compressible à faible pression pour permettre le mouvement du piston. Le piston peut être modulaire pour faciliter les décalages d'assemblage ou de forage[1] dans le corps de vanne. Une fermeture de sécurité en cas de défaillance du joint est envisagée.

Abstract: L'invention concerne des procédés et un appareil permettant de fabriquer un longeron de pale de rotor en matériau composite, une matrice à multiples composants étant utilisée pour former le longeron composite. La matrice est fabriquée en utilisant un certain nombre de composants qui sont assemblés pour donner une structure qui est suffisamment forte pour maintenir la forme de longeron pendant l'assemblage de précuisson, le compactage et la cuisson du matériau composite. Les multiples composants utilisés pour former la matrice peuvent être séparés les uns des autres et facilement retirés du longeron avant ou après la cuisson du matériau composite. Les composants de la matrice peuvent alors être réassemblés et réutilisés pour former d'autres longerons composites.

Title: Method for treatment of oil and/or gas field waste and by product materials
Inventor: HEPBURN MAUREEN BEATRICE
IPC: C05F17/00
Filed: 2007-06-11
Granted: 2014-08-19
Abstract: A method for the treatment of oil and/or gas field waste and by product materials, the method comprising composting the waste material. The present invention is typically suited to the treatment of waste and by product materials from oil and gas wells that are contaminated by organic compounds, such as hydrocarbon residues, either from oil based drilling muds, or from hydrocarbons produced from the well. The composting is typically accomplished by an endogenous microbial population on the composted mixture, and optionally a feeder material to provide N and C sources for the microbes. The composting operation is typically carried out in a composting chamber, and typically an auger or some other tilling device is used to mix the material within the composting chamber.

Abstract: The present invention relates to bituminous compositions suitable for use in paving applications containing bitumen emulsion of performance-grade bitumen that is substantially free of volatile solvents and made by controlling temperature-dependent interfacial rheology through the use of selected emulsifiers. The invention bituminous paving compositions are suitable for the construction of load-bearing pavements with improved compaction to densities similar or superior to those achieved in the conventional hot mix bituminous paving compositions. Cure rate of the invention bituminous compositions is higher than those of cold mix bitumen emulsion-based paving compositions, and at least equal to those of hot mix bituminous paving compositions. Additionally, the invention bituminous compositions develop adhesive strength and load-bearing strength properties at rates comparable to those of hot mix bituminous paving compositions, and at rates faster than those of cold mix bituminous paving compositions.

Title: Produit plat en materiau metallique, en particulier en materiau d'acier, utilisation de ce produit plat ainsi que cylindre et procede de fabrication de ces produits plats
Inventor: HESSE BODO
IPC: B21B27/00

Abstract: L'invention permet de former un produit métallique plat qui présente une structure stochastique ou quasi-stochastique de surface en éléments fins, de telle sorte qu'après une application de peinture typique de l'automobile, cette structure ne puisse être détectée visuellement que faiblement ou même ne puisse pas être détectée. En même temps, dans une topographie de surface formée selon l'invention, le passage entre les plateaux en relief et les creux est formé de flancs accusés. De cette manière, on obtient le résultat que la morphologie de la surface de la tôle fine soit en pratique indépendante de la profondeur effective des creux. Le résultat en est que la morphologie de la surface de la tôle fine d'un produit métallique plat selon l'invention est indépendante du degré de dressage appliqué lors de la formation de la texture fine de la tôle par un cylindre de dressage.

Abstract: A transplanting apparatus which can plant virtually 100% of the seedlings from a nursery tray, while avoid skips when planting which may happen when seeds in a tray row fail to grow into seedlings. This is accomplished by picking up an entire row of seedlings from a tray, transferring the seedlings to a mechanism which eliminates gaps between seedlings, and then discharging the seedlings one at a time to the ground with a desired spacing between the seedlings while having full physical control of the seedlings. A root ball compressor is provided to provide better control of the seedlings as the compressed root balls are less likely to tip over.  and the compressed root balls are easier to be grabbed by the pinch disks.

Abstract: There is provided an ultrasonic inspection apparatus which detects various deviations with respect to an ideal scanning position and achieves, with high accuracy, an ultrasound flaw inspection by autonomously adjusting the deviations. The ultrasonic inspection apparatus according to the present invention is provided with an integrated type ultrasound transducer including an ultrasonic transducer, an integral type ultrasound transducer control unit, an actuator for distance adjustment, an actuator for tilt control, and a distance measuring sensor. The integrated type ultrasound transducer calculates a deviation between a scanning position based on a preliminarily generated scanning path information and an ideal scanning position, and performs a deviation correction processing by autonomously controlling a distance and a tilt between an opening surface of the ultrasound transducer and an inspection region of an object to be inspected in accordance with this deviation.

Abstract: An intraocular lens (30) is disclosed, with an adjustable optic (150) that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic (90) supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may include a cap (93) on the anterior and/or posterior surfaces of the lens. The lens may include a force transfer member (160), such as a hinge, that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The haptic and optic may be refractive index-matched. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.

Abstract: The invention is a process and apparatus for separating liquid mixtures. The process of the invention comprises passing the liquid mixture over a permeable non-porous selective membrane, whereby at least part of the liquid stream passes through said membrane leaving the other side as a vapor, with the remainder of the liquid stream forming a retentate stream.  The vapor is condensed on a condenser surface to give a distillate stream, said condenser surface forming a non-permeable heat conducting separation wall between said distillate stream and a cooling stream which is the feed or retentate stream. The distance between said membrane and said condenser surface is smaller than 10 mm. The vapor pressure of said distillate stream is lower than that of the compounds in the liquid stream for which the membrane is selective, resulting in sufficient driving force for the separation to occur.
