Abstract: An open-pored porous body (11), in particular a carbon component of an aluminium production cell, which is to be exposed to oxidising conditions or chemical attack at high temperatures is treated to protect the body against oxidation or corrosion at high temperatures by impregnating the surface of the body at about ambient temperature with a hot non-saturated liquid (10). This liquid contains a treating agent at a temperature above the temperature of the body. The concentration of treating agent in the hot liquid is such that when the liquid is cooled, before it reaches the temperature of the body, the liquid saturates and treating agent precipitates. A pressure differential is applied to cause the liquid to impregnate into the surface pores of the body (11) and precipitate a layer of the treating agent from the liquid inside the body by cooling as it impregnates the pores of the body. The treating solution preferably comprises soluble boron compounds and, when the body is exposed to high temperature oxidising conditions, the precipitated layer of the treating agent inside the body forms a protective, vitreous layer in the surface pores which protects the body against oxidation.

Granted: 2003-09-30
Abstract: In recent years, the telecommunications industry has witnessed the proliferation of a variety of digital vocoders in order to meet bandwidth demands of different wireline and wireless communication systems. The rapid growth in the diversity of networks and the number of users of such networks is increasing the number of instances where two vocoders are placed in tandem to serve a single connection. Such arrangements of low bit-rate codecs can degrade the quality of the transmitted speech. To overcome this problem in the specific situation involving store-and-forward systems (e.g. voicemail), the invention provides a novel method and apparatus including a plurality of different vocoders that can be selectively invoked to process the voice signal so as to reduce signal degradation. Also, the apparatus has the capability to bypass the vocoder bank when exchanging data with a remote signal processor capable of accepting data frames in compressed format.

Abstract: A problem with mobile radio systems is the potentially harmful interference they may cause to other electronic equipment. Such interference can be dangerous and even life-threatening in hospitals and aircraft. Interference to automobile electronic braking systems, air bag actuators, or train system controls are examples of other areas where radio system interference must be prevented to preserve the safety of operators and passengers. The present invention provides a system whereby mobile radios, e.g. cellular phones, can be operated safely in regions where interference could cause serious problems or can be prevented from operating. The mobile radios are provided with a low power mode of operation and are commanded, via their signalling channels, to operate in the low power mode when within range of a low power signal from a base station within a protected area. In some areas where it may be undesirable for the mobile radio to operate, even at low power levels, the ease station may broadcast an inhibiting signal which will instruct the mobile radio not to operate its transmitter while in the area.

Abstract: Lorsqu'un puits de pétrole est achevé, il est nécessaire de surveiller en fond de trou le débit auquel les produits provenant du puits s'écoulent dans le trou de forage jusqu'à la surface. Un type de procédé et d'appareil précédemment employé à cet effet dans les puits comportant une partie de trou de forage horizontale dans laquelle le fluide est stratifié en couches distinctes de constituants, consiste à utiliser des substances de détection ou de marquage. A l'aide d'un outil injecteur/détecteur, une substance appropriée est injectée dans le fluide et le temps qu'elle met pour arriver à une station de détection en aval est relevé, ce qui donne la vitesse d'écoulement sur la base d'un calcul de distance divisée par le temps. Toutefois, le problème est de faire parvenir la substance de détection ou de marquage, sous forme d'une composition à solubilité (ou à miscibilité) appropriée, dans le fluide du puits de manière à ce qu'elle parvienne dans la couche de constituant désiré. Malheureusement, la simple introduction de la composition au hasard dans le fluide en un endroit quelconque du trou de forage n'est pas satisfaisante, car si ladite composition de marquage est injectée dans la "mauvaise" couche, il lui sera difficile en pratique de migrer vers la cible désirée. Pour résoudre ce problème, il est proposé, selon la présente invention, d'utiliser un appareil d'injection qui comporte une pluralité d'orifices d'éjection (22lp, 22r) espacés (par lesquels la composition de marquage en question peut être éjectée de manière à être injectée directement dans la couche de constituant pertinente choisie), combiné à un dispositif d'orientation (15) qui permet, à l'utilisation, de régler l'orientation de l'outil de manière à ce que les orifices soient chacun placés simultanément dans la couche appropriée. Chaque orifice peut être relié à une source de la composition de marquage adéquate. De préférence, la source est constituée par la combinaison d'un réservoir (13l, 13r) et d'un dispositif de type seringue (12l, 12r) qui peut prélever une certaine quantité de la composition dans le réservoir et ensuite l'acheminer vers l'orifice associé et l'éjecter dans la couche choisie.

Abstract: A plasma ignitor, or plasma source, for igniting a combustible mixture in an internal combustion engine. The ignitor includes at least two spaced apart electrodes dimensioned and arranged such that an outwardly moving plasma is formed when a voltage is applied across the electrodes. The present invention is characterized by its efficient use of input electrical energy for driving the plasma ignitor and by an ignition plasma kernel which is several orders of magnitude larger than that produced by conventional spark plugs. Outward motion and expansion of the plasma kernel is produced by a Lorentz force thereon, arising from interaction between the applied voltage and current between the electrodes, through the mixture, after initial plasma generation in the mixture. Use of very lean combustible mixtures, in which the dilution of the mixture is achieved by use of exhaust gas recirculation, is made possible by the present ignition system. Improvement in engine efficiency, and a major reduction in NO X exhaust gas pollutants are obtained.

Granted: 2010-12-07
Abstract: A new method to capture, purify and expand antigen-specific T lymphocites has been developed using magnetic beads coated with recombinant MHC class I molecules. This method was optimized using homogenous populations of naive T cells purified from mice transgenic for the 2C T cell receptor (TCR). These T cells were captured on beads coated with MHC class I molecules and the relevant antigenic peptides. MHC and peptide specificity was confirmed by the usage of irrelevant MHC peptide combinations. An enrichment of 800 to 1600 fold was measured, using 2C T cells mixed with irrelevant T cells, starting from a 2C T cell frequency of 1/3000. The same approach was used to purify antigen-specific CD8+ T cells from total CD8+ T  cells from naive mice. The recovered cells could be expanded and specifically kill target cells in vitro; they had a significant effect in vivo as well. We expect this procedure to be suitable to purify and expand in vitro tumor- and virus-specific killer T cells for use in cell therapy.

Abstract: The invention is an applicator and process used to fill in the edges of composite panels with resin or emulsions. The applicator is attached to a pressurized canister filled with resin that forces the resin through the applicator's channel, into a space between the applicator's spatula and the panel's edge. The sidewalls of the applicator guide the applicator along the edge of the panel as it is drawn along to fill the edge and also to prevent spill over. The aft-end of the applicator body is a spatula that tapers toward the panel's edge and acts to smooth the resin flush with the panel's sidewalls. A finger guide allows the applicator to work using finger pressure. The applicator is drawn along with the hands, and where the leading edge of the applicator body rests on the panel there is a rounded lip to allow the applicator to traverse smoothly over roughness and imperfections on the panel's edge. The rounded lip feature also functions as a pivot that allows the applicator to be pivoted in such a way that the sidewalls will rise above the panel's edge so that the applicator can clear obstacles like adjoining panels without having to be removed from the panel being filled. Ribbing on the underside of the spatula facilitates the flow of resin over the entire edge of the panel. The applicator may be fashioned to accommodate varying panel thickness or edge profile, such as straight, angled, or bullnosed. The applicator may also be used to apply adhesives to the edges of solid panels.      The invention can alternatively be fashioned for automation.
