Title: Device and procedure to generate steady compound jets of immiscible liquids and micro/nanometric sized capsules
Inventor: BARRERO RIPOLL ANTONIO
IPC: A23L27/00
Filed: 2002-01-31
Abstract: The invention relates to a device and method for generating liquid capillary streams of multi-component immiscible liquids, the diameter of which may range from tens of nanometers to hundreds of microns and to a relatively monodispersed aerosol of electrically charged multi-component droplets generated by rupture of the streams due to capillary instabilities. Said immiscible liquids flow at appropriate volumes through metal needles that are connected to a high voltage source in such a way that all the needles are contained inside one needle. The needles may or may not be placed concentrically relative to one another. The electric forces extrude the streams thereby resulting in diameters ranging from 100 microns to a few nanometers. The device and method disclosed in the invention can be used in fields such as materials science and food technology, wherever generation and controlled handling of structured micrometric and nanometric sized streams is an essential part of the process.

The diver can also select and display standard messages that are factory preset, or custom messages stored by the diver before the dive. A second embodiment is used to communicate text messages by data communication over a wire between divers and a ship, a submarine, an ocean rig or other divers at a distance. Two units of the text communication device are used, each unit connected to one end of the wire, and they function as data communication terminals. It is also possible to connect multiple units to the wire, forming a network. This embodiment also includes a data communication interface such as an ethernet interface, a serial interface or a telephone modem.

Title: Ink divider and associated application program interface
Inventor: DRESEVIC BODIN
IPC: G06F40/00
Filed: 2003-11-13
Abstract: Methods for communicating between an application and an ink divider object (which stores ink strokes to be divided into groups) may include: (a) issuing a divide request to the ink divider object, optionally by the application; (b) in response to the divide request, calling a divide method, which groups the stored ink strokes into one or more groupings of strokes having a first predetermined granularity (e.g., words, lines, paragraphs, sentences, drawings, etc.); and (c) making information regarding the one or more groupings of strokes available to the application. This "information" made available to the application may include, for example, the actual groupings of the strokes, the number of stroke groupings having the first predetermined granularity, machine generated text corresponding to the stroke groupings, or the like. The results of the divide method may be stored in an ink division result object. In some examples, the ink division result object may include the originally divided strokes and allow retrieval of groupings of strokes of various different granularities. This invention also relates to systems for performing the above methods and various data structures used in performing these methods.

Patent CA-2457426-A1 (CA)
Inventor: HAMMOND BLAKE THOMAS
IPC: E21B47/00
Filed: 2004-02-12
Abstract: Method, apparatus and article of manufacture for monitoring and characterizing the operation of a transducer (i.e., motor or pump) downhole. In particular, transducer RPMs are determined by analysis of acoustic information. An acoustical source (signal generator) located on a downhole tool (e.g., a drill string) creates acoustic energy which is received and processed by a receiving unit, which may be located at the surface of a wellbore. The acoustical source is operably connected to the transducer, so that the frequency of the signal produced by the acoustical source corresponds to the speed of the transducer. The acoustic signal of the acoustical source may then be isolated from other acoustical energy produce by downhole equipment, such as a drill bit. Having determined transducer speed by isolation of the acoustic signal, other operating parameters may be determined. illustrative operating parameters include torque, flow, pressure, horsepower, and weight-on-bit.

Abstract: - Méthode et dispositif pour évaluer dans le même temps et avec le même appareillage, des paramètres physiques tels que la perméabilité absolue et la porosité, de fragments extraits d'un milieu poreux naturel ou artificiel fragmenté. - On mesure la porosité des fragments au moyen de tests de pression à l'hélium ou tout autre gaz, suivant un protocole connu en soi. L'enceinte qui les contient, est mise en communication avec un réservoir de volume connu également, contenant de l'hélium sous une pression connue. A l'équilibre des pressions, on peut déduire la valeur du volume solide. On mesure également le volume enveloppe de roche et la masse en fragments. En combinant ces mesures, on détermine la porosité des échantillons ainsi que la densité de la roche. On mesure ensuite leur perméabilité en les immergeant dans un liquide et en mettant l'enceinte en communication avec du liquide initialement sous une pression définie contenu dans un accumulateur de manière à comprimer le gaz piégé dans les pores de la roche. Par le biais d'une modélisation de l'évolution du volume de liquide injecté dans l'enceinte, et d'un ajustement itératif, on détermine les valeurs des paramètres physiques. - Applications par exemple à des mesures pétrophysiques à partir de déblais de forage ou de carottes concassées.

Abstract: Cette invention concerne un procédé permettant d'extraire du pétrole dans une formation souterraine pétrolifère. Ce procédé consiste à insérer une ou plusieurs paires d'électrodes dans le sol à proximité d'une formation pétrolifère. On crée ensuite une tension entre les électrodes de manière à produire un champ électrique dans la formation pétrolifère. Pendant l'application de la tension, on manipule le courant pour induire des réactions d'oxydation et de réduction dans les composants de pétrole. Ces réactions d'oxydo-réduction ont pour effet d'abaisser la viscosité du pétrole et, par là même la résistance capillaire à l'écoulement du pétrole, lequel peut être extrait par un puits d'extraction.
