Patent WO-9720954-A1 (WO)
Title: Procede duplex simplifie de traitement de minerais et/ou concentres de nickel en vue de la production de ferronickels, de fers au nickel et d'aciers inoxydables
Inventor: BLANDY CHARLES WILLIAM DOUGLAS
IPC: C21B11/08
Filed: 1996-11-29
Abstract: Traditionnellement, les procédés de production de ferronickel, de fer au nickel et d'acier inoxydable comportent un nombre d'étapes excessivement élevé et consomment énormément d'énergie; ces procédés présentent des difficultés de raffinage et ils aboutissent à la formation d'une scorie qui ne peut être pleinement exploitée en tant qu'agrégat dans les matériaux de chaussées et dans les bétons. Tous ces inconvénients entraînent des coûts de production élevés. Il est possible de remédier à ces inconvénients en procédant à une fusion directe, suivie d'une étape de raffinage. Le matériau de départ, qui est composé d'un minerai et/ou d'un concentré contenant du nickel, associé à une source en fer constituant le matériau d'appoint, est chargé à l'intérieur d'un four de fusion en bain (50) fonctionnant en mode réduction/oxydation, en continu ou par intermittence. Une scorie réductrice (57), contenant une matière charbonneuse, est formée au dessus d'un alliage de métal fondu (55), et de l'oxygène (60, 61) est soufflé à travers des tuyères (58, 59) à l'intérieur de la scorie charbonneuse (57) pour produire un gaz réducteur et dans l'espace au dessus de la scorie (57) pour oxyder tout monoxyde de carbone excédentaire, de façon à ce qu'une couche (56) de scorie au repos existe entre la couche de scorie turbulente (57) et la couche de métal fondu (55). La réduction en gouttelettes de métal se produit dans la couche supérieure (57) de la scorie et ces gouttelettes s'infiltrent à travers la couche de scorie au repos (56) dans la couche de métal (55), ces deux couches étant siphonnées ou soutirées, lorsque la capacité de remplissage est atteinte. La charge minérale peut être constituée de minerais et/ou de concentrés séchés et/ou calcinés de sulfure de nickel et/ou de latérite de nickel avec ou sans minerai de fer et éventuellement de chromite de fer en tant que source de chrome. On ajoute des flux du type oxyde de calcium de façon à conserver une scorie basique, qui est maintenue fluide à une température élevée comprise entre 1700 °C et 2000 °C. La seconde étape de raffinage et de finition est effectuée dans un équipement de décarburation suivant le procédé AOD et/ou dans un convertisseur.

Filed: 1989-07-21
Abstract: This director is designed for robot technology useful in vocational training and for production purposes. It is distinct with a simplified technological construction, which ensures the attainment of a geometric similarity between the kinematic chain of the director with the prime operating kinematic chain, and the enhanced operational abilities and functional ease of the operator and the response options. The device (1) itself includes two functionally detached parts: I and II. Part I consists of a stationary base, to which a kinematic chain, designed on a module principle, together with a handle, is mounted via the first single-axis hinge joint. Part II consists of a second handle with two stages of mobility, supported by two single-axis hinge joints, which are intercepted at 90 degree axis. The joints of both parts are equipped with co-axial sensors recording angle displacements and permissible limitations, which determine the end-joint spin positions. The director is connected to a remote control system, which also includes: executive Study Joint Robot 2 ("Robco 1"); a control unit (3) (personal computer); a multi-channel interface connected via an AD transformation module (4), which makes an electric connection between the potential readers (5) of the director (1) and the control unit (3).

IPC: E21B29/06
Filed: 2000-10-20
Abstract: L'invention concerne un système à sifflet déviateur une passe, qui comprend une fraise combinée associée à un sifflet déviateur. La fraise combinée une passe comprend une lame supérieure et une lame inférieure réunies par un cône qui s'élargit vers la lame supérieure. Un sifflet déviateur est fixé à la réduction de tiges de forage par des boulons de cisaillement. Un tenon-guide situé sur le sifflet déviateur est affronté à la réduction de tiges de forage, entre les lames supérieure et inférieure, pour chevaucher le cône lorsque la réduction de tiges avance le long du sifflet déviateur. De préférence, les boulons de cisaillement se fixent à la lame inférieure, dont le calibre est inférieur à celui de la lame supérieure, si bien que la taille relative du calibre des lames permet à la lame supérieure de sortir du tubage de revêtement avant la lame inférieure, pendant le forage. Une fraise de type 'watermelon' et une fraise de colonne peuvent être installées au-dessus de la lame supérieure. La lame supérieure présente un bord d'attaque carré, ce qui diminue l'usure sur son diamètre extérieur.

Title: Systeme sans fil multifaisceau reparti
Inventor: SMITH ADRIAN
IPC: H04L12/56
Filed: 2003-11-21
Abstract: L'invention concerne un réseau sans fil comprenant des noeuds auxquels peuvent accéder des terminaux sans fil par l'intermédiaire de liaisons d'accès sans fil, couplés par l'intermédiaire de liaisons de transit sans fil utilisant plusieurs faisceaux d'antennes directionnelles. Ces noeuds s'organisent et s'adaptent automatiquement lorsque des noeuds sont ajoutés et d'autres changements se produisent. Les nouveaux noeuds utilisent une technique de balayage du faisceau pour écouter les signaux provenant de noeuds existants et répondent en conséquence pour entrer dans un réseau. Les noeuds déjà établis transmettent chacun de manière récurrente un message de bienvenue sur les faisceaux non utilisés qui sera reçu par un nouveau noeud. Les incidents de transmission dus, par exemple, à une interférence sur une fréquence de voie de transmission, sont détectés et traités automatiquement par transmission sur une autre fréquence. Le balayage du faisceau peut être amélioré à l'aide de techniques faisant intervenir des faisceaux qui se chevauchent et la diversité.

Abstract: TELECOMMUNICATIONS SWITCHING SYSTEM     Abstract A switching system is described in which routing information, which may be associated with packets originating in cellular calls, is divided into information which does not change as the subscriber crosses a cell boundary, and information which does change as the subscriber crosses a cell boundary. Routing procedures associated with the information which does not change as the subscriber crosses a cell boundary are established and stored in the memory of the switch at the beginning of the call. However, routing procedures associated with the information which does change as the subscriber crosses a cell boundary may be derived from the header information of each packet as it arrives at the appropriate portion of the switch.

Patent CA-2007167-A1 (CA)
IPC: G06F12/08
Filed: 1990-01-04
Abstract: ABSTRACT OF THE DISCLOSURE           In a data processing system in which each of the data processing units is implemented using pipeline techniques and has a cache memory unit employing a store through strategy, the time required to prepare a write instruction operand address can be substantially shorter than the time required by the execution unit to prepare the associated write instruction operand.  In order to utilize time difference, apparatus is included in the execution (E-)cache unit for storing the write instruction operand address during the preparation of the associated write instruction operand.  After storing the write instruction operand address, a next address is entered in an input register of the E-cache unit. When the newly entered address is associated with a read instruction, does not conflict with the write instruction operand address, and produces a "hit" signal when applied to the E-cache unit tag directory, the read instruction is processed by the E-cache unit.  When a second write instruction operand address is entered in the input register, the read instruction operand address conflicts with the stored write instruction operand address or the read instruction operand address results in a "miss" when applied to the E-cache tag directory unit, the address is stored in the input register until the write instruction operand has been determined and the associated  write  instruction  has been processed by the E-cache unit.

In a closed condition of the closure, aligned aper-tures of the two closure members may receive the locking member to hold the assembly closed.  A part of one of the closure members having the aperture is flexible and tensile and has a flexure position such that, when an opening force is applied to the assembly with the locking member extend-ing through the apertures, the flexible part is flexed under tension and is urged against an opposing surface of the other closure member formed with the corresponding aperture.  This flexing action places the locking member mainly in shear while minimizing any bending forces upon the locking member.    - i -

IPC: H04N21/434
Filed: 1990-08-07
Abstract: ABSTRACT         The disclosed asynchronous transfer mode (ATM) switching network evenly scatters individual cells of an ATM data stream in the first half of the network and routes them to their intended destination in the second half of the network.  The network is constructed from interchangeable switching modules each preferably containing only two stages of switching elements, with each switching element having a common memory, thus reducing the component count by one third compared to Clos' 3-stage non-blocking modules.  Each individual module provides a switched path from any selected one of its module inputs to any selected one of its module outputs, with the common memory acting as a buffer until a path becomes available to the desired module output.          Since the additional stages between the module's input stage and the module's output stage typically used to provide a non-blocking module are dispensed with, not only the component count, but also the transmission delay through the switching network may be reduced.
