Title: Methods and compositions for acidization in a wellbore
Inventor: MOOREHEAD ALAN W
IPC: C09K8/52
Filed: 2007-01-19
Granted: 2012-06-05
Abstract: Improved acidization methods and compositions are provided wherein the compositions comprise an aqueous solution comprising one or more esters or polyesters of hydroxy acid or of glycerol. The solution may be placed in a well where the esters or polyesters undergo hydrolysis. The hydrolysis of the esters or polyesters occurs at a slower reaction rate than that of several other known acidization esters, such as diethyleneglycol diformate, at temperatures higher than 600C or even higher than 1000C. Thus, the acidization solution may be distributed substantially throughout a region in a well where acidization is required before hydrolysis is completed, despite being exposed to relatively high temperatures. The hydrolysis may result in the slow release of an acid that is capable of consuming all or most of an undesirable substance in the well, e.g., a filter cake.

Abstract: A drip shield includes cover members that define a protective canopy over sample receptacles to prevent unwanted material from being deposited into the receptacles. The cover members cooperate to define at least one access hole through the drip shield to permit access to a sample receptacle by a pipette tip through the access hole. One of the cover members is moveable with respect to another cover member between a closed stated defining the access hole and an open state permitting a pipette tip extending through the access hole to be laterally conveyed relative to the drip shield and out of the access hole. In a preferred embodiment, a system control feature automatically determines if a pipette tip might have been left in a sample receptacle and extending through the access hole of the drip shield and thereby cause the sample receptacle and pipette tip to be conveyed laterally relative to the drip shield while the one cover member moves from the closed to the open state to permit the pipette tip to be conveyed out of the access hole.

Title: Double spread-head carousel winder
Inventor: BAUMHOFF ALFONS
IPC: B65H18/10
Filed: 2007-07-31
Granted: 2011-03-29
Abstract: A carousel coiler with two coilers, which are mounted in a rotatable rotor, are rotatably driven independently of each other, are intended for the successive, continuous winding of metal strip and each have spray heads, which comprise a number of segments that can be moved in a spreading manner, are supported on axially displaceable wedge-shaped directing surfaces and on which the coilers can be cyclically moved in each case from a starting position into a strip-coil transfer position by turning of the rotor, is to be developed in such a way that a pivot-into-place outside bearing becomes superfluous, that the coil or the coil to be wound is always supported on both sides in every position, and that the carousel coiler can be used both for winding up and unwinding coils. For this purpose, it is proposed that the rotor comprises two rotor discs (2, 2'), which are opposite each other and connected to each other by at least one hollow cross-member (3) and that the rotor carries at least two double spray-head coilers.

Abstract: L'invention concerne des séquences d'ADN, en particulier des éléments augmentant la transcription et respectivement, l'expression (éléments TE) ainsi que leur mise en AEuvre dans un vecteur d'expression en association avec un amplificateur, un promoteur, un gène de produit et un marqueur de sélection. L'invention décrit la séquence N°1 ainsi que les éléments TE-01, -02, -03, -04, -06, -07, -08, -10, -11 ou -12. Par leur faible taille, on préfère en particulier TE-06, -07 ou TE-08. La séquence N°1 dérive d'une région de séquence, qui se trouve en amont de la région codante du gène Ub/S27a de cellules CHO. Les éléments TE effectuent une augmentation de l'expression du gène de produit lors d'une intégration stable dans le génome eucaryote, de préférence dans le génome CHO-DG44. Les effets de position chromosomique sont ainsi maîtrisés, masqués ou annulés. Ainsi, non seulement la quantité de hauts producteurs d'une charge de transfection, mais encore le taux absolu d'expression sont augmentés de jusqu'à quinze fois.

Abstract: A hydrogen-resistant optical fiber particularly well-suitable for downhole applications comprises a relatively thick pure silica core and a depressed-index cladding layer. Interposed between the depressed-index cladding layer and the core is a relatively thin germanium-doped interface. By maintaining a proper relationship between the pure silica core diameter and the thickness of the germanium-doped interface, a majority (preferably, more than 65%) of the propagating signal can be confined within the pure silica core and, therefore, be protected from hydrogen-induced attenuation problems associated with the presence of germanium (as is common in downhole fiber applications). The hydrogen-resistant fiber of the present invention can be formed to include one or more Bragg gratings within the germanium-doped interface, useful for sensing applications.

Abstract: Une méthode est présentée pour la détection de la configuration d'un réseau ayant une ligne secondaire dotée d'une pluralité de compteurs d'alimentation et de compteur de transformateur de distribution qui y sont couplés et un ou plusieurs compteurs clients et/ou des modules de configuration client couplés aux transformateurs de distribution. La méthode comprend les étapes où chacun des compteurs d'alimentation transmet un signal unique sur la ligne secondaire. Les compteurs de transformateur de distribution déterminent alors la phase de chacun des signaux uniques et transmettent la phase de chacun des signaux uniques à un collecteur de données en les accompagnant d'un identifiant unique de compteur de transformateur de distribution. La relation de connectivité entre les compteurs d'alimentation et les compteurs de transformateur de distribution est ensuite extrapolée en comparant l'information de phase transmise par les compteurs de transformateur de distribution. La relation entre les compteurs clients et les compteurs de transformateur de distribution peut également être déterminée en faisant en sorte que chaque compteur de transformateur de distribution transmette l'identificateur du compteur de transformateur de distribution à tous de leurs compteurs clients respectifs, qui le transmet au collecteur de données en l'accompagnant de leur identificateur de compteur client. La méthode permet également de déterminer la phase dans laquelle le compteur de transformateur de distribution est connecté en analysant l'angle de phase d'un signal de compteur de distribution démodulé.
