Title: Procede et appareil polyvalent pour la regulation de fluide dans un tubage de trou de forage
Inventor: LATIOLAIS BURNEY J JR
IPC: E21B33/14
Filed: 2000-04-26
Granted: 2008-06-17
Abstract: L'invention concerne un appareil de fond de trou doté d'un mandrin supérieur (320) accouplé par cisaillement à un mandrin inférieur (360). Un manchon (300) est raccordé par cisaillement dans le mandrin inférieur (360). Le fonctionnement de l'appareil est déclenché par la chute d'une balle d'un premier diamètre (70) de la surface de la terre. La balle (70) passe dans le mandrin supérieur (320) et s'enfonce dans le manchon (300). Sous l'effet de l'augmentation de la pression de pompage au niveau de la surface de la terre, le mandrin inférieur (360) est séparé du mandrin supérieur (320) par cisaillement. Sous l'effet de l'augmentation de la pression de pompage, le mandrin inférieur (360) peut être envoyé dans le fond du train de tiges tubulaires, contre un collier flottant ou une autre surface de réception formant bouchon. Lorsque l'on veut séparer le mandrin supérieur (320) du train de tiges, on fait tomber une deuxième balle plus grosse (68) depuis la surface de la terre, de sorte qu'elle se loge dans le mandrin supérieur (320). Sous l'effet d'une augmentation de la pression de pompage supérieure, le mandrin supérieur (320) est séparé du train de tiges tubulaires.

Abstract: A collaborative Web browsing session may take place over a network, allowing the presenter on a first computer to direct the audio and visual components of a browser on one or more second computers. The second computer is instructed to log into a control site that downloads an active control, such as an applet, to the second computer. The present invention allows a collaborative Web browsing session ("session"), as created by the presenter and witnessed by one or more users on second computers, to be recorded and archived by the control site. When a user of a computer is connected to the control site through a communication network such as the World Wide Web, that user may log into the control site and request to view an archived session. The session will then be replayed by the control site on the user's computer, directing the audio and visual components of the browser on the user's computer as if the user was attending the live session. The recorded session replays the events of the live session in real time such that the playback experience contains the same audio and visual events that took place when the session was originally being recorded.

Abstract: A laundry appliance can be selectively operated in either manual or automatic modes of operation. In the automatic mode, a laundering operation is initiated upon receiving a single cycle input parameter from the user, preferably through an LCD touch screen display, while relying on additional operating cycle parameters established by factory preset settings or prior consumer established preferences. In accordance with a preferred embodiment of the invention, a consumer need merely select a single cycle parameter and the appliance will start based on temperature and other setting parameters taken from memory. However, even with the automatic start feature activated, the user will still be able to adjust pre-established cycle parameters by changing default values after the cycle has started.

Abstract: L'invention concerne des procédés de commande d'un support de transmission à perte avec une onde d'énergie définie par une fonction de forme d'onde exponentielle. Le temps de propagation et l'atténuation de l'onde est fonction d'un coefficient exponentiel, et sa vitesse de propagation est essentiellement constante et indépendante du déplacement. L'utilisation de relations entre la vitesse de propagation, le coefficient exponentiel, l'atténuation ainsi que les paramètres de ligne de transmission permet de modéliser efficacement divers supports de transmission. On peut également déterminer des paramètres de ligne de transmission, des coefficients exponentiels de forme d'onde, une atténuation et/ou des vitesses de propagation inconnus par utilisation de ces relations. Par modulation du coefficient exponentiel, des informations peuvent être codées sur une forme d'onde.

Granted: 2009-09-29
Abstract: A vial adapter having a needle-free valve, a sharpened cannula used to perforate a vial's rubber stopper, and a circular array of claws of different lengths to engage vial closures of different diameters. The array of claws includes a first set of claws each having a first length extending inwardly from the periphery of the housing of the adapter and a second set of claws alternating with the first set of claws and each having a longer length. The second set of claws are mounted so that they deflect and plastically deform out of the way in the case where the adapter is engaged with a vial that exceeds a predetermined size. The housing includes a shroud that is at least as long as the sharpened cannula to protect medical personnel who use the adapter from inadvertent punctures. The needle~free valve includes a resiliently deformable piston element with a naturally open bore. The interior of the piston provides a fluid flow path through the adapter. In one embodiment, the first set of claws of the adapter may be used with a vial closure of at approximately 20 mm in diameter and the second set of claws may be used with a vial closure of approximately 13 to 17 mm in diameter.

Abstract: In the LAPDm a short message service is implemented by pre-emption of every second signalling message when there is a short message to be sent. Same pre-emption mechanism is also needed when the RLC/MAC protocol is used on the data link layer instead of the LAPDm. The mechanism is provided by defining at least two different identities to be used with frames transmitted on the signalling channel; and pre-empting frames on the MAC at least on the basis of the identity relating to a frame. The identities are preferably identified on the basis of the signalling radio bearer of the frame.
