Inventor: RAINE FLORENT
IPC: F01D17/16
Filed: 2004-06-18
Abstract: Le mécanisme de commande de calage (position angulaire) d'aube de stator dans un turboréacteur peut être réglé séparément pour deux étages d'aube voisins commandés par un moyen actionneur 10 commun. Pour cela, la barre de synchronisation 9 entre les mécanismes menant aux deux étages prend une inclinaison déterminée par une liaison à ergot 22 et rainure 23 avec le carter, tandis qu'une autre liaison à ergot 26 et rainure 27 est ménagée entre la barre de synchronisation 9 et un des mécanismes. Des lois de déplacement fortement non linéaires entre les deux mécanismes peuvent ainsi être commandées d'après les formes et les directions des rainures. Figure 2.

Abstract: A transceiver apparatus (110) for creating a wireless personal local area network between a computer terminal (7) and one or more peripheral devices (9, 13, 23). A separate transceiver (110) is connected to the computer terminal (7) and to each peripheral device (9. 13, 23). The transceivers (110) can be connected to the terminal (7) or the peripheral devices (9, 13, 23) either internally or externally. A low power radio (112) is used to communicate information between the computer terminal (7) and the peripheral devices (9, 13, 23). Different transceivers (110) can be used for modifying the carrier frequency and power of the local area network. A microprocessor (120) is located inside each transceiver (110) and controls the information flow of the transceiver including the communication protocol which allows each device (7, 9, 13. 23) to know if other devices (7, 9, 13, 23) are communicating, which devices (7, 9, 13, 23) are being communicated to, and selectively address the peripheral devices (9, 13, 23).

Abstract: The current invention concerns new bioadhesive polymers incorporated with biodegradable components. The bioadhesive components used are polycarboxylic acids, while the biodegradable components can be any synthetic degradable polymers, particularly biodegradable polyesters whose degradation products are small molecular esters. The two polymer components may be covalently bound to each forming graft, block or random copolymers, examples of which include poly(acrylic acid)-graft-poly(lactic acid) (PAA-g-PLA) and pol(lactic-co-glycolic acid)-g-poly(acrylic acid) (PLGA-g-PAA). The two components may also be incorporated into one material by forming non-covalent interpolymer complex via, for examples, hydrogen bonding, ionic bonding or hydrophobic bonding.  Typical examples in this category include the hydrogen bonding interpolymer complex formed between poly(methacrylic acid) and poly(lactic acid)-b-poly(ethylene glycol)-b-poly(lactic acid) tri-block copolymers. The new materials may be used without a treatment agent to provide a lasting acidic pH  environment or used with a treatment agent as a delivery system.

Filed: 2003-08-01
Abstract: Various grinding machine components are made of superhard materials, including certain machine grade ceramics, including such materials as carbides, nitrides, borides, oxides, oxynitrides, or any other ceramic component. The component may either be a solid piece of ceramic or wear resistant material, or may have an insert or a piece of the wear resistant material adhered to a metallic substrate base for use within the machine. Graded materials may also be used with a gradient from a 100% concentration of ceramic at one surface, and gradually changing into a 100% metal at the other surface, would be advantageous. These superhard materials overcome some of the previously experienced problems as they will hold closer tolerances and resist wear better than other materials.

Abstract: A process for modification of ad content to be displayed in a particular geographic location is "localized" to include content modified to fit the particular locale. A remote Ad Player is linked through wired or wireless connection or network (LAN, MAN or WAN) to a central Ad Server that knows the location of each device. A plurality of ads created as a combination of digital files are stored in a database associated with the Ad Server. Each ad includes a control file and a list of components, and for each component, a localization table identifies location specific modifications of at least some of the components. Since the Ad Server knows the location of each Ad player, it can localize an ad before it is sent to a particular Ad player, or alternatively, the Ad Server can send the ad file package and the appropriate component files to the remote Ad Player and allow the Ad Player to perform the localization function as it assembles the Ad.

IPC: C12N15/11
Filed: 2003-09-30
Abstract: La présente invention concerne une méthode de synthèse de microréseaux renfermant des oligonucléotides différents dans une seul et même zone caractéristique du réseau. La méthodes repose sur l'emploi de techniques communes à la synthèse de microréseaux, mais limite la durée de dosage initial à la lumière des zones caractéristiques sélectionnées de manière à ne déprotéger qu'une proportion calculée des composés formant la couche de liaison du réseau. Les composés déprotégés initialement sont recouverts d'un groupe de protection non photosensible, tel que du di-méthoxy-trityle, afin d'inhiber leur implication dans la synthèse d'un premier groupe de brins d'ADN créés sur ce réseau. Une fois synthétisé ce premier groupe de brins d'ADN, le traitement du groupe d'origine déprotégé peut se poursuivre avec la création d'un ou plusieurs autres groupes de brins d'ADN dans la même zone de caractéristiques que le premier groupe de brins d'ADN. La présente invention concerne également des microréseaux obtenus par cette méthode.

Title: Method of reducing toxicity of retinoids
Inventor: HIGHLAND MARGARET A
IPC: C07C51/43
Filed: 2004-01-16
Abstract: A method of minimizing or reducing the toxicity of a retinoid having a free carboxyl group is described. The method comprises the step of esterifying the carboxyl group of the retinoid with a highly sterically hindered alcohol. The resulting retinoid esters are rendered much less toxic than the starting or parent retinoid. This process provides a retinoid ester analog of reduced toxicity so that it may be administered orally with minimal side effects and with a much greater therapeutic window.
