Abstract: La présente invention concerne une méthode permettant d'obtenir un procédé plus efficace et plus économique d'alimentation de ruminants au moyen d'un régime faible en protéines brutes tout en réalisant le même taux de rendement laitier et de composants laitiers que pour des ruminants bénéficiant d'un régime protéique normal. Plus particulièrement, le procédé implique d'alimenter des ruminants avec un supplément de nourriture animale comprenant au moins une protéine soustraite à la dégradation ruminale en combinaison avec un régime plus faible en protéines brutes. Ce procédé permet d'obtenir une approche unique de formulation nutritionnelle en ce qu'il permet jusqu'à 50 % de réduction d'ingestion protéique brute tout en maintenant l'alimentation protéique intestinale et le taux de rendement en composants laitiers. Il en résulte alors une réduction des pertes azotées dans les urines animales et une réduction des coûts d'alimentation.

Granted: 2007-07-31
Abstract: A traffic source emits packet-based traffic (ATM) carrying a plurality of variable bit rate calls. The traffic is managed by: measuring a parameter of the current traffic output from the source, using the measured parameter in a comparison with a parameter which is indicative of available capacity on the link; and providing a control signal for varying the operational state of the traffic source according to the comparison. The operational state can be varied by choosing a combination of a coding rate, selected from a range of coding rates, and selective use of silence suppression. A cell policing algorithm can be used, such as the GCRA. The system lowers transmission quality of voice traffic before lowering transmission quality of the data traffic, and uses silence suppression for voice traffic before using lower coding rates for the traffic source.

Title: Implantable delivery device with self adjustable exit port
Inventor: DIONNE KEITH E
IPC: A61K9/52
Filed: 1998-03-10
Granted: 2006-12-19
Abstract: A delivery device having a first chamber containing an osmotic agent, 'a membrane forming a wall of the first chamber through which fluid is imbibed by osmosis, a second chamber containing a beneficial agent to be delivered, and a moveable piston separating the two chambers. In fluid communiation with the second chamber is an orifice which comprises a slit valve. In the presence of pressure, the beneficial agent pushes through the slit, opening up a channel for delivery of the beneficial agent and creating flow. Because the slit remains closed in the absence of flow (or when the pressure is below the pressure required to open the slit), back diffusion of external fluids is eliminated when the slit is closed, which prevents contamination of the beneficial agent in the second chamber by external fluids. In addition, forward diffusion of the beneficial agent out of the capsule is prevented when the slit is closed. The slit valve opens only to the minimum dimension required to allow the flow generated by the osmostic pumping rate. The slit valve also allows a flow path to open around any obstruction in the slit valve to prevent clogging.

Abstract: An apparatus and a method for controlling oilfield production to improve efficiency includes a remote sensing unit that is placed within a subsurface formation, an antenna structure for communicating with the remote sensing unit, a casing joint having nonconductive "windows" for allowing a internally located antenna to communicate with the remote sensing unit, and a system for obtaining subsurface formation data and for producing the formation data to a central location for subsequent analysis. The remote sensing unit is placed sufficiently far from the wellbore to reduce or eliminate effects that the wellbore might have on formation data samples taken by the remote sensing unit. The remote sensing unit is an active device with the capability of responding to control commands by determining certain subsurface formation characteristics such as pressure or temperature, and transmitting corresponding data values to a wellbore tool. The inventive system includes an antenna structure that is for delivering power and communication signals to the remote sensing unit. In one embodiment, the antenna structure is formed on an external surface of a wellbore casing. In another embodiment, the antenna structure is formed on a downhole tool such as a drilling collar or a cased hole wireline tool. For those embodiments in which the antenna structure is formed on a cased holed wireline tool, a casing joint is provided that includes nonconductive windows for allowing RF  signals to be transmitted from within the casing to the remote sensing unit and from the remote sensing unit to the wireline tool. An inventive method therefore includes providing RF power through the inventive antenna system to the remote sensing unit to wake it up and to place it into an operational mode. The method further includes receiving modulated data values from the remote sensing unit through the antenna system that are then transmitted to the surface where operational decisions for the well may be made.

Abstract: The present invention is directed to, in a general aspect, a nudger for a mixed mail feeder and, in particular, to an apparatus and method of providing and detecting proper position in a stack of mixed mail. The apparatus, generally, comprises a nudger arm for detecting proper positioning of the mailpiece and a lean detection arm for detecting proper lean of the mailpiece with respect to the nudger. The method comprises generally, a determination that when the lean detection arm and the nudger arm are in a position indicating that the lead mailpiece is in the proper position, the stack of mixed mail is decelerated and fed to, for example, a separator, for further processing. The deceleration is performed at a slow rate and provides for a predetermined amount of over travel by the stack of mixed mail. This ensures proper contact of the lead mailpiece with the nudger rollers for feeding the mailpieces for further processing. The nudger rollers continue to feed the lead mailpieces until one or both of the lean detection arm and the nudger arm move out of the position(s) for proper mailpiece feeding.
