Title: Procede et systeme de fabrication d'un rembourrage absorbant pour articles absorbants
Inventor: WERNER EDWARD ERICH
IPC: D04H1/70
Filed: 1997-11-25
Abstract: La présente invention concerne des procédés et des systèmes destinés à fabriquer un rembourrage absorbant pour un article absorbant. Ils comportent un appareil de façonnage qui donne forme au matériau du noyau absorbant, un dispositif qui applique une couche de rétention sur la première surface du noyau absorbant, et enfin, un appareil pulvérisant pour vaporiser les fibres de la résine fondue sur la seconde surface du noyau absorbant. Les fibres forment une couche de stabilisation sur le noyau absorbant augmentant ainsi son intégrité. L'appareil pulvérisant comprend une buse dotée d'une ouverture qui permet à la résine de s'écouler et d'autres ouvertuers pour évacuer les différents gaz et donner un motif aléatoire aux fibres de la résine fondue au moment où les fibres sont pulvérisées sur la seconde surface. On peut également vaporiser la résine sur les première et seconde parties de la couche de rétention s'étendant des bords du noyau absorbant vers l'extérieur, de sorte que les couches de rétention et de stabilisation enveloppent le noyau abosrbant. Dans un autre mode de réalisation, on peut placer une seconde couche de rétention sur la seconde surface du noyau absorbant et espacer les première et seconde couches de stabilisation vers l'extérieur et les déposer sur le noyau absorbant.

Abstract: A device and method for shutting off the flow of gas to a structure, such as a residence, when a fire is detected in the structure. The device has a fire detector for providing a status signal to indicate the presence of fire in a structure, an actuator in communication with the fire detector, and a shut-off valve located on a gas line and connected to the actuator. When the status signal is received by the actuator, the actuator causes the valve to close, thereby shutting off the flow of gas to the structure. The device also includes one or more of the following: a secondary electric power source, disturbance prevention circuitry, a shut-off valve position indicator, a manually operated means of closing the shut-off valve, and an alarm indicator for indicating the presence of fire in the structure. The method involves detecting a fire and providing a status signal to an actuator. Then the actuator moves the shut-off valve from an open position to a closed position. The method also involves providing an indication of the shut-off valve position.

Abstract: La présente invention concerne un transistor à effet de champ en carbure de silicium. Le TEC est formé sur un substrat monocristallin en carbure de silicium. Une grille en matériau isolant présentant une paire de parois latérales espacées est formée sur le substrat. Le matériau isolant comprend un premier matériau d'isolation recouvert d'une couche électroconductrice. Le substrat se compose de régions de base légèrement dopées placées partiellement sous les parois latérales de la grille et s'étendant jusque dans le substrat exposé. Des régions de source fortement dopées associées aux régions de base légèrement dopées sont alignées avec le substrat exposé. Sur le côté sus-jacent des substrats se trouve une région de drain permettant de former le TEC. L'invention concerne également un procédé de fabrication d'un transistor à effet de champ. Le transistor est formé dans un substrat monocristallin en carbure de silicium. La formation d'un transistor sur le substrat en carbure de silicium consiste à déposer une première couche électro-isolante sur le substrat. Ensuite, une couche électroconductrice est déposée sur la première couche isolante puis une seconde couche électro-isolante est déposée sur la couche conductrice. Les étapes suivantes consistent à retirer partiellement la seconde couche isolante et à exposer une partie de la première couche conductrice afin d'obtenir deux régions espacées du substrat en carbure de silicium pour la formation des régions de base légèrement dopées. Ensuite, le substrat aligné avec la partie exposée de la première couche conductrice reçoit une légère implantation d'un dopant afin de former des régions de base légèrement dopées. Alors, on forme une couche d'un troisième matériau isolant sur les parois latérales du second matériau isolant. Les étapes suivantes consistent à retirer la couche conductrice exposée non alignée avec le second matériau isolant et un troisième matériau isolant.

Abstract: A method and apparatus for enhancing the cell error ratio and the cell misinsertion rate for a given cell loss ratio is provided. A predetermined number, C, of ATM cells (150, 250) are packed together and encoded using a strong t-error correcting BCH block code, such as a Reed-Solomon code to produce an encoded block (162, 262). After transmission, the received data segment (156, 256) may include s errors. The data segment (156, 256) is decoded, and if s > t, decoder failure occurs with very high probability and the data segment is discarded. The CER obtained is superior to present ATM systems. The decoded block is unpacked into C ATM cells (160, 260). Optionally, the header fields (164, 264) of the C ATM cells may be decoded. In most cases where errors are present in the header, nonzero syndrome occurs with high probability, and the C ATM cells (160, 260) are discarded. The CMR obtained is superior to present ATM systems. The delivered ATM cells (160, 260) are virtually error free with very high certainty.

Title: A method for obtaining leak-off test and formation integrity test profiles from limited downhole pressure measurements
Inventor: HACHE JEAN-MICHEL
IPC: E21B49/00
Filed: 2000-02-08
Abstract: The present invention presents a method that effectively restores the real-time advantage of annular pressure while drilling (APWD) measurements taken during certain drilling operations that require the mud circulation pumps to be turned off (a "pumps-off" condition). APWD data, such as pressure measurements, is obtained from instruments and related electronics within the BHA. APWD data can be measured, stored and even processed in the BHA during a pumps-off condition for subsequent processing or communication of a reduced amount of data to the driller at the surface.

Title: Method & apparatus for forming features in cans
Inventor: KNIGHT PHILIP JOHN
IPC: B21D15/02
Filed: 1998-10-05
Abstract: A method and apparatus for mechanically reshaping and/or forming textured features in the side wall of metal can bodies (5) in which a can body is mounted on a profiled mandrel (15) and rolled along a second madrel or rail (25), which is also profiled. The tools are made from hard material but either the mandrel carrying the can or the second mandrel or rail is resiliently mounted. This mounting has been found to facilitate control of the depth of the profiled features formed in the can body. In particular, the problem of depth variability which will arise due to expansion of the machine and tooling in normal running conditions, or variability in thicknesses in the can body is avoided. Typically, the can body is clamped between complementary unformed regions on the tools during forming so as to prevent wrinkling or localised thinning of the can side wall.

Title: Three dimensional graphical manipulator
Inventor: GOLIBRODSKI OLIVIER
IPC: G06F3/033
Filed: 2000-04-11
Abstract: A method and apparatus for manipulating a computer generated model and visualizing a change in projection plane before entering a projection creation command. After selection of a projection plane on the 3-D model, a generative drafting document can be created wherein the projection plane becomes the plane of the screen. The system can display a visualization of the projection of the model in plane with the screen, without generating a fully computed projection. Display of the visualization can provide increased efficiency in processing time as compared to a fully computed projection. The system can also display a graphical manipulator including a circular central region with a button in the middle, wherein clicking on the button can be used as a command to the system requesting creation of the projection. The graphical manipulator software tool can also include quadrants, wherein each quadrant is associated with a direction in relation to an orthogonal axis. The four quadrants can be defined as left, right, up and down: Clicking on a quadrant can cause the projection plane to rotate by 90 degrees, or other predetermined amount, around two orthogonal axes of the model in the projection plane. The direction of rotation will correlate with the quadrant selected. In addition, the manipulator tool can include a pin tracking the circumference of a circle displayed on a computer,screen. Selection of the pin and rotation can cause the projection plane of a computer generated model to rotate about an axis which is perpendicular to the projection screen.
