Abstract: In certain example embodiments of this invention, a window unit may include a vacuum IG (VIG) unit as an inboard lite and a monolithic lite (e.g., with an optional low-E coating thereon) as an outboard lite. A dead air space may separate the inboard and outboard lites.  A highly insulated frame may be used to support the inner and outer lites. The VIG  unit may be partially embedded or supported in the insulative frame, so that the insulating frame separates the VIG unit inboard lite from the outboard lite thereby reducing conductivity around the edges of the window unit so that R- value can be increased (and U-value decreased). In certain example embodiments, the total R-value of the window unit is at least about R-8, and more preferably at least about R-IO (compared to the much lower R-values of conventional IG  units).

IPC: B07C5/36
Filed: 2008-08-29
Abstract: Systems and methods for accumulating articles on transport conveyors, for efficiently merging articles, and for automatically controlling sortation speed are disclosed. Transport conveyor beds upstream of an accumulation conveyor bed may be controlled to more densely pack articles, as well as to more timely deliver articles to the downstream subsystem when accumulation terminates.

Filed: 2007-05-21
Abstract: La présente invention concerne des compositions contenant des mélanges de polysaccharides polyanioniques et de polysaccharides polycationiques composés de dérivés oligosaccharides de chitosane. Dans les compositions de cette invention, ces mélanges se révèlent être solubles dans des environnements aqueux malgré la formation de complexes ioniques entre les polysaccharides acides et les dérivés de chitosane. Ces compositions présentent également un comportement rhéologique marqué avec une augmentation inattendue de la viscosité et de la viscoélasticité, malgré les poids moléculaires moyens relativement faibles des polysaccharides utilisés. Cette solubilité et ce comportement rhéologique rendent les compositions de cette invention particulièrement intéressantes pour des applications biomédicales, plus précisément pour la viscosupplémentation, en particulier dans le domaine des pathologies articulaires et de la chirurgie ophtalmique.

Abstract: Automated make-up and break-up methods and apparatus for rotary oil well drilling are presented. The apparatus includes a drilling database storing tubular type records, a torque wrench having a spinner, and a controller. During make-up, the controller looks- up tubular type records stored in the drilling database in order to configure the torque wrench and/or the spinner to connect an additional tubular section to a tubular string or to disconnect a connection between tubulars in accordance with tubular type parameters. Sensors are employed on various drill rig components and reported sensor values are monitored. Timers are started concurrent with the initiation of various make-up and break-out steps. Exceptions are thrown when sensor values are out-of-range or when steps take too long to complete. Advantages are derived from speeding-up drill rig operations.
