Title: Apparatus and methods for the production of powders
Inventor: BALLARD STEPHEN G
IPC: C01F7/424
Filed: 2000-09-01
Abstract: Metallic powders are formed by the electrically exploded wire (EEW) process.  An apparatus (20) for manufacturing such powders includes a closed loop recirculating gas path between a reaction chamber (100) and an extractor (32).  A wire (31) is delivered from a source (400) along a wire path from ambient conditions outside the chamber to within the chamber. Within the chamber, a first electrode (200) has an aperture circumscribing the wire path and a second electrode (203) is located proximate to a terminal end of the wire path. A source (26) of electrical energy applies a discharge voltage between the electrodes to explode the length of wire therebetween to form an initial particulate. The initial particulate may be selectively extracted and processed to produce desired powders, in particular, energetic powders which are passivated for stability under ambient conditions.

Abstract: La présente invention concerne un raccord à vis à partie femelle et partie mâle. Il est conçu pour réunir par vissage les tubes de puits de pétrole, tout en évitant que les contraintes s'exerçant sur l'extérieur de la partie femelle dépassent la limite élastique propre au métal de base du raccord. On cherche ainsi à se prémunir d'une corrosion sous contrainte attaquant le raccord. De fait, on veille à ce que le facteur de gène (T) s'appliquant au filet reste dans des limites définies calculées sous la forme d'une fonction. Les paramètres pris en compte pour cette fonction sont le diamètre intérieur (D¿1?) de la partie mâle, le diamètre (D¿2?) du pas de vis au niveau du diamètre de base, le diamètre extérieur (D¿3?) de la partie femelle, la pression interne de charge (Pi), la limite élastique (.sigma.y) du métal de base, et le module élastique (E) de Young. Cela permet la réalisation d'un raccord à vis convenant au montage des tubes de puits de pétrole.

Title: A method and an apparatus for a quick retransmission of signals in a communication system
Inventor: ESTEVES EDUARDO A S
IPC: H04W92/10
Filed: 2001-04-13
Abstract: A transmitting terminal, transmits signals in a form of packets to a receivi ng terminal, if the packet was intended for the receiving terminal, if so, the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics  match, the packet is forwarded for further processing. If the quality metric s fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. If delivery of the packet in accordance with the aforementioned description fails, retransmissi on in accordance with conventional sequence-number-based schemes, e.g., radio link protocol, is attempted.

Inventor: GAN HONG
IPC: H01M4/66
Filed: 2002-12-05
Abstract: A new sandwich positive electrode design for a secondary cell is provided comprising a "sacrificial" alkali metal along with a cathode active material. In the case of silver vanadium oxide, the sacrificial alkali metal is preferably lithium. Upon activating the cells, the lithium metal automatically intercalates into the silver vanadium oxide. That way, the sacrificial lithium is consumed and essentially lithiates the silver vanadium oxide. This means that cathode active materials, such as silver vanadium oxide, which before now were generally only used in primary cells, are now useful in secondary cells. In some use applications, silver vanadium oxide is more desirable than typically used lithiated cathode active materials.

Title: Second order complementary global positioning system/inertial navigation system blending filter
Inventor: MILLER RONALD J
IPC: G08G5/00
Filed: 2001-07-24
Abstract: A second-order filter that blends accurate position information from a one source, and velocity information from another source, both suitably scaled, in a second-order complementary filter. The filter is arranged such that an internal integrator (106) maintains a value that represents the difference in the rate of change of the accurate position information, and the velocity input of the other source. This velocity difference is applied to another integrator (114) outside the filter, whose initial condition is the position error between the two sources to the second order filter. The output of this latter integrator (114) is a correction signal that grows at a rate equal and opposite to the rate of error built-up of position data from the source whose velocity is used in the second order filter. This correction signal is summed (120) with the original position signal. In addition, the output of the second order filter may be used as a highly accurate position signal.

Abstract: L'invention concerne un appareil et un procédé de réflectométrie de cohérence, en particulier destinés à une tomographie par cohérence optique. Elle concerne en particulier le chemin du champ lumineux dans le bras échantillon. Le champ lumineux réfléchi dans le bras échantillon est amplifié avant d'être reçu sur des moyens de combinaison, ces moyens permettant de recevoir le champ lumineux réfléchi provenant du bras échantillon aussi bien que le second champ lumineux réfléchi provenant du bras de référence. Il est ainsi possible de diriger sensiblement toute l'énergie lumineuse du bras échantillon vers les moyens de combinaison et d'obtenir complètement l'utilisation de l'amplification du champ lumineux réfléchi puisque, de préférence, seul le champ lumineux réfléchi est amplifié par l'amplificateur optique. On obtient ainsi un rapport signal sur bruit amélioré en même temps qu'une augmentation de la profondeur maximale de pénétration. L'appareil est ainsi utile pour l'obtention de biopsies optiques de tissus transparents et non transparents, ainsi que dans d'autres domaines techniques dans lesquels le rapport signal sur bruit amélioré permet l'utilisation de cet appareil.
