Inventor: MARTIN DAVID G
IPC: A61B5/308
Filed: 1999-01-28
Granted: 2006-03-28
Abstract: A connector is disclosed to facilitate the testing of a control line or lines adjacent a bottomhole assembly. A running tool is connected to a lower portion of the connector which is, in turn, connected to the bottomhole assembly. The running tool allows testing of the control line adjacent the bottomhole assembly and there-after, the operation of components of the bottomhole assembly. me running tool is removed and the upper portion of the string, including the mating portion of the connector at its lower end, is inserted into the wellbore. The connector components are self-aligning and lock to each other downhole to complete the production tubing and the control line tubing to the surface. Multipile control lines are envisioned between the surface and the bottomhole assembly. Multiple connectors can be used in a given production string, and provisions can be made for operation of a multiplicity of downhole components from the control line system which extends along the production tubing.

Abstract: A fuel refilling assembly for receiving a filling nozzle to open and close a filler neck of a fuel tank. The refilling assembly has a housing attached to the filler neck to receive the filling nozzle. A pressure valve and a vacuum valve are mounted to the housing. The valves move between seated and unseated positions to automatically equalize the pressure within the filler neck, a filler pipe and the fuel tank. The refilling assembly is characterized by a first flap pivotally mounted to the housing and engaging the vacuum valve for automatically moving the vacuum valve from the seated position to the unseated position. The first flap is pivoted when the filling nozzle is partially inserted within the filler neck. Once the vacuum valve is disengaged, any pressurized fuel vapors within the filler neck, filler pipe and fuel tank are vented to the atmosphere. The venting occurs before the filling nozzle opens the filler neck which ensures a safe filling operation.

Title: High speed weighted fair queuing system for atm switches
Inventor: HE LINHAI
IPC: H04L12/56
Filed: 1999-09-02
Granted: 2005-11-08
Abstract: Methods and apparatus for an ATM network for implementing a fair servicing of all connections during a back-logged condition through the use of a weighted fair queuing technique. The system is particularly suited for systems where the packets/cells ere of a fixed size. Although some important approximations are made in the proposed implementation, all of the properties of an ideal weighted fair queuing algorithm are preserved. The sorting methods and apparatus are advantageous in that it is possible to maintain appropriate servicing of connections without sorting all of the individual connections. This may be accomplished by pro-sorting each of the individual virtual circuit connections into a finite number of predetermined bins according to a weight associated with the connection. Thereafter, only the bins need be sorted without having to sort each of the individual connections. Further aspects of the invention include storing the bins in a matrix with an offset value dependent upon the current potential of the bin. In this manner, the overall sorting required to determine the next connection to service is substantially reduced. Accordingly, the invention is suitable for implementations having transmission speeds of multiple gigabits-per-second.

Granted: 2009-07-21
Abstract: Multiple digital watermarks, each of which has different characteristics, are embedded in a document. The characteristics of the various watermarks are chosen so that each of the watermarks will be affected in a different manner if the document is subsequently copied and reproduced. The detection process or mechanism reads each of the watermarks and compares their characteristics. While wear and handling may change the characteristics of the digital watermarks in a document, the relationship between the characteristic of multiple digital watermarks in a document will nevertheless give an indication as to whether a document is an original or a copy of an original.

Abstract: Cette invention se rapporte à un procédé permettant de préparer une résine naturelle en liquéfiant du bois, de l'écorce, des résidus forestiers, des résidus de l'industrie du bois ou toute autre biomasse, à l'aide d'une pyrolyse rapide, afin de former des vapeurs de produits et du charbon de bois. Après retrait du charbon de bois des vapeurs de produits, un premier groupe de composés est retiré des vapeurs de produits, par refroidissement rapide, afin de créer une vapeur de produit sélectionnée restante, d'où est tirée une résine naturelle. Cette résine naturelle présente une teneur phénolique totale comprise entre environ 30 % et environ 80 % (en poids) et elle se caractérise en outre par une odeur de fumée agréable. Il a été surprenant de découvrir que cette résine naturelle se prête à une utilisation dans des formulations d'adhésifs, sans qu'il soit nécessaire de recourir à tout autre technique d'extraction ou de fractionnement. Des adhésifs contenant jusqu'à 60 % de résine naturelle ont été préparés et testés dans la production de planches, et on a découvert qu'ils possèdent des propriétés similaires associées aux résines disponibles dans le commerce. Cette résine naturelle peut remplacer le phénol, ou à la fois le phénol et le formaldéhyde dans les résines contenant du phénol. De même, cette résine naturelle peut remplacer une partie essentielle des constituants des résines contenant de l'urée.

Title: Processes and intermediates for preparing 2-substituted piperidine stereoisomers

IPC: C07D211/02
Filed: 1998-05-26
Granted: 2008-10-14
Abstract: Processes and intermediates for preparing 2-substituted piperidines such as 2- substituted d-threo piperidines are provided. In preferred embodiments, the processes of the invention comprise the steps of reacting a 2- substituted pyridine with hydrogen in the presence of a catalyst in an alkanoic acid, and adding an alkyl alkanoate to the resulting mixture of threo and erythro 2-piperidine stereoisomers to precipitate alkanoate salts of the erythro stereoisomers preferentially with respect to alkanoate salts of the threo stereoisomers. The erythro salts thenare reacted with aqueous base to form the corresponding mixture of erythro amide free bases, which are reacted with a suitable organic acid resolving agent in an alkyl alcohol solvent to form acid salts of the l-erythro stereoisomers preferentially with respect to the d-erythro stereoisomers. The l-erythro acid salts are then reacted with aqueous base to form the l-erythro piperidine amide free base which, in turn, is epimerized to produce the desired d-threo product by treating it in an organic solvent with an alkali metal alkoxide.
