Abstract: Cette invention se rapporte à un alliage à base de cuivre qui comprend, en poids, 2,8 à 5,0 % de Sn, 0,4 à 3,0 % de Bi, plus de 0 et moins de 0,35 % de Se et qui se caractérise en ce qu'il possède des propriétés mécaniques améliorées, tout en assurant un degré spécifié d'usinabilité et la bonne qualité d'un produit de fonte utilisant cet alliage; à un lingot de fonte produit au moyen de cet alliage; et à des pièces conçues pour être mises en contact avec des liquides et fabriquées par formation de cet alliage. Cet alliage de cuivre contient des quantités réduites d'éléments rares (Bi, Se et similaire) comme éléments de remplacement du Pb, ce qui permet de baisser son coût de production, et il possède également des propriétés mécaniques comparables ou supérieures à celle d'un alliage de bronze classique (CAC406) disponible sur le marché, tout en assurant une usinabilité comparable à celle de l'alliage CAC406. Ces avantages ont été obtenus par une prise en considération correcte des vraies propriétés des éléments rares (Bi, Se et similaire) comme éléments de remplacement du Pb et par la suppression des défauts structurels grâces à l'élucidation de l'effet qu'exerce la réduction des éléments de remplacement du Pb sur la bonne qualité d'un produit de fonte.

Granted: 2005-11-29
Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of tree cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells, abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.

Granted: 2011-02-08
Abstract: A wellbore evaluation system evaluates mechanical wear and corrosion to components of a well system including a production tubing string positionable in a well and a sucker rod string movable within the production tubing string. A deviation sensor determines a deviation profile of the well, a rod sensor senses and measures wear and corrosion to the sucker rod string as it is removed from the well to determine a rod profile, and a tubing sensor senses and measures wear and corrosion to the production tubing string as it is removed from the well to determine a tubing profile. A data acquisition computer is in communication with the sensors for computing and comparing two or more of the respective deviation profile, rod profile, and tubing profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.

Title: Fluid flow measurement using optical fibres
Inventor: RAMOS ROGERIO T
IPC: E21B47/09
Filed: 2004-03-22
Granted: 2012-07-17
Abstract: A method of monitoring fluid flow uses an optical fibre having a heatable coating. The fibre is disposed within flowing fluid, and the heatable coating heated so that heat is transferred from the coating to the fluid. Optical measurements of the temperature of the heatable coating are made, where the temperature of the heatable coating depends on the flow velocity of the flowing fluid, and the temperature measurement is used to derive information about the flow. The coating may be an electrically resistive layer on the outer surface of the fibre, that is heated by passing electric current through it. This allows distributed flow measurements to be made. Alternatively, discrete measurements can be made if the coating is provided as a thin film layer on an end facet of the fibre. The coating is heated by directing light at a wavelength absorbed by the thin film material along the fibre.

Abstract: The method involves determining resources previously allocated to a wireless link for each traffic station of information data representative of occupation rate, based on traffic type. A primary allocation of the resources between different links including marginal allocations is determined. A secondary allocation between different types of traffic of the resources allocated to the links by the primary allocation is determined. The primary allocation of the resources between different links is determined based on the occupation rates as per the traffic type. The secondary allocation is determined by taking into account the occupation rates as per traffic type. An independent claim is also included for a traffic station for point to multipoint type communication network.

Abstract: A non-compression vessel, such as a digester, is employed for the chemical preconditioning of the chips followed by a fiberizing device to break the preconditioned chips down to fiber bundles, which are then washed before a high consistency chemical treatment. The digester may be one such as used in conventional chemical pulping of wood with or without screens for the extraction of chemical. If extracted this chemical could be recirculated to the digester with treatment in the circulation loop such as heating or the addition of dilution or other chemicals. This digester may be hydraulic or vapor phase (that is contain a vapor space within the digester), and operate in either a continuous or batch fashion. This digester allows for the discharge of material without the use of a screw mechanism. The digester treated material is then defiberized to convert the chips into course fiber bundles, which then is washed and dewatered. The washed and dewatered pulp is then treated with alkali peroxide chemicals to develop brightness and other pulp properties.
