Patent CA-2379433-C (CA)
Title: Sanitary absorbent article having a tear-resistant flange seal
Inventor: SIMARD JEAN-SEBASTIEN
IPC: A61F13/15
Filed: 2002-03-27
Granted: 2010-09-28
Abstract: A sanitary absorbent article such as a sanitary napkin, or incontinence pad having a cover layer that is fluid permeable, an absorbent system and a liquid--impervious barrier layer under the absorbent system to prevent collected liquid to escape therefrom. The fluid-permeable cover layer is attached to the liquid--impervious barrier layer to form a flange seal enclosing the absorbent system. The flange seal includes two zones, namely a first zone and a second zone separated by a common boundary, each zone manifesting different mechanical properties. The first zone that resides closer to the outer edge of the flange seal is more resistant to shear stresses than the second zone residing near the inner edge of the flange seal. This arrangement reduces the likelihood of the flange seal being torn during use of the sanitary absorbent article.

Abstract: Preferably a turbofan engine includes a fan blade (22), rotatably mounted within a generally cylindrical casing (18) for rotation about a lengthwise extending central axis. An annular lining (24, 26) is mounted within the casing between a tip of the fan blade (22) and the casing (18). The lining (24, 26) seals the tip of the fan blade (22) within the casing (18). The lining (24, 26) includes a brush seal (34) that extends around an inner circumference of the casing (18), and has a plurality of bristles (38) that extend radially inward from the seal (34). A retaining membrane (36) extends around the brush seal (34), preventing the bristles (38) from extending substantially in a radial direction from the brush seal (34). The retaining membrane (36) is adapted to release the bristles to extend radially inward to occupy a region between the tip of the fan blade (22) and the casing (18) upon a radial excursion of the fan blade (22). The bristles (38), once released, at least partially seal the tip of the fan blade (22) and the casing (18) reducing air recirculation at the blade tip.

Abstract: Les procédés connus permettant de produire de grandes quantités d'extraits concentrés à partir de matériaux bruts solides tels que du café moulu et torréfié ne sont pas tout à fait adaptés à la production d'extraits de café de haute qualité dégageant un arôme et un parfum riches et conservant le caractère variétal du café torréfié dont ils proviennent. La présente invention concerne des procédés de filtrage permettant de produire lesdits extraits concentrés de café de haute qualité à partir d'extraits plus dilués au moyen de l'élimination du solvant. L'invention concerne également des procédés suffisamment flexibles et échelonnables pour être utilisés dans une large gamme d'applications, y compris pour produire des quantités industrielles d'extraits pour l'industrie des boissons et des aliments. L'invention concerne également des procédés et un appareil qui peuvent produire des quantités élevées d'extraits hautement concentrés de "qualité gourmet", destinés à être utilisés comme aromatisants, comme concentrés de boissons et comme fragrances. Les extraits concentrés à solvant réduit obtenus au moyen des procédés d'élimination de solvant selon l'invention peuvent être utilisés avantageusement pour des applications requérant des extraits de café de haute qualité ayant une concentration élevée de solides solubles de café, par exemple comprise entre au moins environ 6 % en poids et 40 % en poids, et un taux élevé de rétention de caractère variétal d'arôme et de fragrance.

Abstract: IP server W and gateway server GWS transmit data in HTML format in response to a request from mobile unit MS. At this stage, in the HTML data, the personal identification information request data string is added to a URL of the page corresponding to a service, which requires user authentication. As the HTML data is received by mobile unit MS, the user carries out an inputting operation to designate the URL while the image corresponding to the HTML is displayed on the liquid crystal display unit. Then, mobile unit MS reads out personal identification information from ROM, and transmits to mobile packet communication network MPN. IP server W carries out user authentication on the basis of personal identification information transmitted from mobile unit MS in this manner.

Granted: 2009-05-19
Abstract: The invention concerns a suction substructure (2) for the setting of one or more conductor casing strings (14) in connection with drilling of at least one underwater well, preferably a petroleum well, and where the use of a suction substructre (2) renders possible the installation of conductor casing by means of known piling technique and by means of a suitable surface vessel, e.g. a suitable boat. The suction substructure (2) consists of a substructure body, which is joined in a pressure sealing manner, and which is shaped with a downwards open end part (8), which is set some way down in the seabed sediments (22). Thereupon water is pumped out of the suction substructure (2), which causes a negative pressure in the suction substructure (2), and where the suction substructure (2) thereby is pressed further down into the seabed sediments (22). The suction substructure (2) is in addition in its upper end fitted with at least one guide opening (10) and possibly an appurtenant guide funnel (12), and an appurtenant releasable and pressure sealing lid (32), and where the guide funnel (12) will be able to guide and give lateral support to a conductor casing string (14) during its subsequent installation.

Abstract: L'invention concerne un procédé de construction d'un modèle géologique tridimensionnel de volume terrestre de sous-surface dans lequel les échelles de résolution de types de données diverses multiples (102, 104, 106, 108, 110), comprenant des données sismiques (106), sont prises en compte en générant des modèles de bande passante à fréquence multiple (111) et les combinant ensemble afin de former le modèle géologique complet (120). Le modèle sera de préférence généré pour chacune des bandes passantes à basse fréquence, une bande passante de moyenne fréquence et une bande passante à haute fréquence. Lorsque les données sismiques sont intégrées au procédé de réalisation du modèle, la bande passante de fréquence sismique constitue le modèle de bande passante de moyenne fréquence. Le procédé consiste également à mettre à jour (112) des modèles de bande passante de fréquence tentative par l'optimisation de valeurs de propriété de roc attribuées pour chaque modèle tentatif, conformément aux critères géologiques spécifiés. On obtient une telle optimisation grâce à la perturbation (118) des valeurs de propriété de roc, de manière à ce que le contenu de la fréquence de chaque modèle soit maintenu.

Granted: 2010-05-04
Abstract: A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. The piston channel provides a passage for communication of infusion medium to an outlet chamber located at one end of the piston channel. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. In the retracted position of the piston, a piston chamber is formed between the piston and a valve member and is filled with infusion medium. As the piston is moved to its forward position, the piston chamber volume is reduced and pressure within the piston chamber increases to a point where the pressure moves the valve member into an open position. When the valve member is in the open position, medium from the piston chamber is discharged into an outlet chamber located on the opposite side of the coil relative to the armature. An outlet is provided in flow communication with the outlet chamber, for discharging infusion medium from the outlet chamber.
