Abstract: La présente invention porte sur un système de filtre de lavage continu à contre-courant, par gravité, à double étage, permettant de filtrer les contaminants de l'eau. Ce système de filtrage comporte un premier filtre composé de sable (10a) et chargé d'un influent. Le système de filtrage comporte des points d'injection pour la coagulation et la désinfection aux produits chimiques. Le filtre composé de sable (10a) est raccordé en série à un second filtre composé de sable (10b) de configuration similaire. Le premier filtre (10a) est constitué de sable à gros grains (23) et le second (10b) de sable à grains fins (28). L'influent du second filtre (10b) provient du déversoir (24) du premier filtre (10a). L'eau évacuée du second filtre (10b) est réintroduite dans l'influent qui est acheminé dans le premier filtre (10a). Les matières rejetées du premier filtre sont acheminées vers un point résiduaire.

Abstract: L'invention porte sur un procédé et un appareil servant à contrôler le fonctionnement d'une source génératrice d'impulsions sismiques en mer dans des conditions de mer forte en surface, ladite source étant composée de plusieurs éléments. Le procédé consiste dans un premier temps à déterminer la forme du trajet suivi par les éléments à un point qui se situe, dans le temps, juste avant que chaque élément de la source ne soit amorcé. Une fois que la forme du trajet est connue, on détermine la position verticale relative de chaque élément par rapport à un point de référence fixe. On peut alors régler les temps d'amorçage de chaque élément, pour faire en sorte que les crêtes de pression des impulsions primaires s'interfèrent de façon constructive les unes avec les autres. Dans une forme d'exécution préférée, une pluralité d'inclinomètres reliés au harnais sur lequel les dispositifs sont suspendus permettent de mesurer l'angle d'inclination à partir duquel on peut déterminer la forme du trajet et régler en conséquence les temps d'amorçage.

Title: Rectangular cathodic arc source and method of steering an arc spot
Inventor: GOROKHOVSKY VLADIMIR I
IPC: C23C14/35
Filed: 1999-04-12
Granted: 2008-12-30
Abstract: The invention provides an arc coating apparatus having a steering magnetic field source comprising a plurality of electrically independent closed-loop steering conductors disposed in the vicinity of the target surface, each steering conductor being controlled independently of the other steering conductors. Increasing the current through one steering conductor increases the strength of the magnetic field generated by that conductor relative to the steering conductor along the opposite side of the cathode plate, shifting the magnetic field on the opposite side of the cathode plate transversely. Selective unbalancing of the steering conductor currents thus increases the effective breadth of the erosion zone to provide more uniform erosion of the target surface. The steering conductors may be disposed in front of or behind the target surface of the cathode plate. In a further embodiment, groups of steering conductors are disposed along opposite sides of the cathode plate. By selectively applying a current through one conductor in each group, the path of the arc spot shifts to an erosion corridor defined by the active steering conductor. The invention also provides a plurality of internal anodes disposed within the plasma duct, for deflecting the plasma flow and preserving a high ionization level of the plasma. The invention also provides a magnetic focusing system which confines the flow of plasma between magnetic fields generated on opposite sides of the coating chamber. The plasma focusing system can be used to deflect the plasma flow off of the working axis of the cathode, to remove the neutral component of the plasma which otherwise constitutes a contaminant, by disposing the plasma focusing coils in progressively asymmetric relation to the working axis of the cathode, to deflect the flow of plasma along a curvate path toward a substrate holder. The invention also provides a shield at floating potential, restricting the cathode spot from migrating into selected regions of the target evaporation surface outside of the desired erosion zone. The shield may be positioned immediately above the region of the target surface in the vicinity of the anode, protecting the anode from deposition of cathodic evaporate and providing better distribution of cathodic evaporate over the substrates to be coated.

Title: Telephony and data network services at a telephone
Inventor: ALLAN WILLIAM
IPC: H04L12/66
Filed: 1999-06-07
Granted: 2010-09-21
Abstract: A packetised data network includes IP telephones (ITs) and a network intelligence (NI). All of the keys of each IT are "soft" keys (i.e., they have no fixed function). The NI associates a configuration data structure with the IT which correlates the keys with functions, and, based on this, may control the display of the IT to indicate the current function of certain of the soft keys. Some of the functions are requests for data services at the telephone (e.g., video or programmed audio over the internet). When a user requests such a service with a key press, the NI sets up the service between the data source and the telephone. This may require associating a new configuration data structure with the keys of the IT. The IT user may activate multiple data services through the NI.

Labels printed with fixed information are provided on a master roll. The endmost label is printed with variable information, separated from the master roll, and then assembled into the decal assembly.     For use, the releasable web is peeled back to reveal the adhesive web, the label, and the backing web. The decal (i.e., the label and the adhesive web covering label) can then be separated from the surrounding adhesive web and the backing web and applied to a surface.

Abstract: An edge protector for a fenestration product is integrally formed of a single sheet of corrugated paperboard that has been perforated, slit, scored, glued, and folded in a particular manner so as to be generally flat in overall configuration prior to being placed in use. At the time of installation, the protector is partially unfolded out of its flat plane to assume an overall generally transversely L-shaped configuration, having a pair of legs intersecting one another at right angles to form a receiving corner for the face and side margins of the product. One leg of the protector forms a flap that covers a marginal portion of the face of the product when the protector is fitted onto the product, while the other leg forms a second flap that covers a marginal portion of the sides of the product. A stiff, relatively short spacer flange comprising a double layer of the material glued together projects edgewise from the outside of the corner in the opposite lateral direction from the side flap to keep the face of the product spaced away from foreign objects. Wrapping of the protector around an outside corner of the product is facilitated by the provision of tear-out tabs embodied in the face flap so that the appropriate tab aligned with the corner of the product may be torn out to leave an empty notch in the flap at that location. The absence of material at the corner of the product eliminates the structural rigidity otherwise afforded by the face flap at that location to enable the protector to more readily bend around the corner.
