Title: Procede de recuperation de phenols a faible poids moleculaire, de furfural, d'alcool furfurylique et/ou de cellulose ou de residus a forte teneur en cellulose
Inventor: HERMESCEC BRANKO
IPC: C10B53/02
Filed: 1999-11-24
Abstract: L'invention concerne un procédé de récupération de furfural, d'alcool furfurylique, de phénols à faible poids moléculaire et/ou de cellulose ou de matières à forte teneur en cellulose, à partir d'une matière lignocellulosique. Le procédé consiste à introduire un gaz vecteur à l'intérieur d'une chambre de réaction pour faciliter un effet de lit fluidisé et acheminer des produits de réaction et des résidus hors du réacteur par entraînement; à placer dans la chambre de réaction une charge d'alimentation comprenant une matière lignocellulosique particulaire présentant une dimension granulométrique déterminée; à dégrader la charge d'alimentation dans la chambre de réaction dans une atmosphère oxygénée et à une température comprise entre 250 °C et 320 °C; et à refroidir la charge d'alimentation dégradée et le gaz vecteur afin de déposer des résidus solides entraînés dans le gaz vecteur et de condenser un produit liquide.

Title: Viscometre rotatif en ligne et procede de mesure associe
Inventor: LAHAUT HUGHUES
IPC: G01N3/00
Filed: 2002-05-17
Abstract: L'invention concerne un viscomètre rotatif équipé d'un moteur (2) qui commande un ensemble rotatif (3) passant par une ouverture (4) pour pénétrer dans un liquide (1) soumis à essai afin de mesurer les forces de cisaillement exercées par ce liquide (1) sur l'ensemble rotatif (3). Pour empêcher que le liquide (1) ne s'échappe par l'ouverture (4) du fait d'une pression du liquide (p1) au niveau de cette ouverture (4), le viscomètre comprend un moyen qui crée une contre-pression (p2) au niveau d'un vide situé entre l'ensemble rotatif (3) et l'ouverture (4). Grâce à cette contre-pression (p2), aucun dispositif d'étanchéité solide n'est nécessaire, ce qui améliore la durabilité et la robustesse du viscomètre, et le simplifie par l'élimination de contre-mesures autrement nécessaires pour prendre en compte les forces de frottement parasites exercées sur l'ensemble rotatif (3) lorsque de tels dispositifs d'étanchéité solides sont présents.

Title: Segment de concentricite
Inventor: SWIDERSKI JOSEPH J
IPC: F01D25/00
Filed: 2000-06-07
Abstract: L'invention concerne une méthode d'assemblage d'une turbine à gaz employant un segment de concentricité (1) pour compenser les tolérances d'assemblage. Lors de la rotation, les extrémités (8) des pales de la turbine à gaz (3) décrivent une surface de rotation concentrique à l'axe (5) de l'arbre. En raison des tolérances cumulées lors de la fabrication et de l'assemblage des pièces, l'axe de l'arbre est, de façon invariable, radialement excentrique à l'axe du moteur dans la position axiale de la turbine. L'excentricité d'assemblage se situe dans une gamme entre zéro et une tolérance d'assemblage admissible prédéterminée. L'invention concerne également le positionnement d'un segment de concentricité (1) avec ; une surface cylindrique externe (18) engageant la surface cylindrique interne (19) du boîtier moteur ; et une surface cylindrique interne engageant la surface cylindrique externe de l'enveloppe de turbine. L'excentricité des surfaces cylindriques externe et interne du segment de concentricité (1) se situe dans une gamme entre zéro et une tolérance d'assemblage admissible prédéterminée, afin de corriger l'excentricité d'assemblage des pièces fixes et mobiles d'une manière simple et rapide.

Title: Complexes d'hydrocarbyl phosphinimine/cyclopentadienyl du groupe 4 et leur utilisation dans la polymerisation des olefines
Inventor: SPENCE RUPERT EDWARD VON HAKEN
IPC: B01J31/18
Filed: 2000-08-24
Abstract: L'invention concerne de nouveaux complexes organométalliques du Groupe 4, caractérisés en ce qu'ils comprennent un ligand de phosphinimine et au moins un ligand de cyclopentadiényle. Certains de ces complexes présentent un comportement inhabituel lorsqu'on les examine à l'aide de techniques de résonance magnétique nucléaire (NMR). On a isolé des cristaux de complexes bien définis, et on les a analysé par radiocristallographie. On a découvert que ces complexes pouvaient être des catalyseurs de polymérisation, qui de manière étonnante sont plus actifs que leurs analogues de métallocène simples.

Title: Plan de decodage de ligne pour echantillonnage double dans des reseaux de pixels a 3 transistors
Inventor: PEARSON MICHAEL
IPC: H04N5/357
Filed: 2001-12-12
Abstract: La présente invention concerne un procédé et un appareil autorisant une séquence de lecture de type « volet roulant » dans un réseau de pixels qui est lu par mise en oeuvre d'une technique d'échantillonnage double, les lignes de pixels étant réinitialisées une seconde fois dans chacun de leurs cycles pour un second échantillonnage lors de l'accès aux lignes pour une lecture. Chaque pixel est ainsi échantillonné afin de comparer son niveau de tension après intégration à son niveau de tension lorsqu'il est réinitialisé.

Title: Rotary drill bit for drilling through sticky formations
Inventor: ZIJSLING DJURRE H
IPC: E21B10/43
Filed: 1989-10-20
Abstract: A drill bit for drilling through sticky formations, such as chalk or marl, comprises a plurality of waterways (4) for transporting drilling fluid and rock flour to the gauge of the bit. These waterways have in downstream direction gradually increasing cross-sectional areas A, the increase of size of said areas along the length of a waterway being at least substantially proportional to the squared radius r thereof from the central axis (10). In this manner the rock flour velocity remains equal or decreases in downstream direction in the waterways so that the risk of rock flour accumulation and compaction is reduced.
Patent CA-2001487-A1 (CA)
IPC: B24D3/34
Filed: 1989-10-25
Abstract: ABSTRACT OF THE DISCLOSURE    A surfacing pad is produced by dispersing abrasive particles in a flexible, water absorbent matrix that is secured on a flexible, fabric substrate, which functions as a reservoir for a liquid. By applying to the pad a small quantity of liquid sufficient to wet the matrix and to saturate the substrate, it is possible by rubbing the surfaces of a workpiece and the wetted matrix to create an abrasive surfacing gel between the workpiece and the pad substrate, thus eliminating the need for directing a slurry or other liquid onto the workpiece during a surfacing operation.

Title: Method of tapering end of capillary tube bore
Inventor: CHRISTOFF WILLIAM R
IPC: C03C25/10
Filed: 1989-10-26
Abstract: Abstract of the Disclosure A device for connecting optical fibers is formed by inserting one or more fibers into at least one end of a capillary tube.  The bore is tapered to facilitate fiber insertion.  To taper the end of a bore, the tube is rotated about its longitudinal axis while a first narrow stream of abrasive particles is directed onto the tube end.  The axis of the first stream is located off the axis of the tube bore, thereby forming a taper that is spherical rather than conical.  A second stream, the axis of which is coaxial with the bore, is then directed onto the tube end to remove that portion of the tapered aperture adjacent the bore, thereby forming a more funnel-shaped aperture.

Patent CA-2010117-A1 (CA)
Inventor: FORNEY G DAVID JR
IPC: H04L27/34
Filed: 1990-02-15
Abstract: In a so-called trellis shaping modulation system, instead of mapping a digital data sequence into a sequence of signal points drawn from a finite-dimensional signal point constellation as in typical coded modulation, the data sequence is mapped into a sequence of signal points drawn from a so-called trellis constellation of available infinite-dimensional sequences so that there is no single N-dimensional constellation used repeatedly in each N dimensions. The region occupied by the available sequences in sequence space is shaped to minimize the required power; i.e., preferably the region is an approximation to the Voronoi region of the trellis code (where the trellis code is not just a repeated lattice code).
