Patent CA-2246841-A1 (CA)
Title: Cycloseparator for removal of coarse solids from conditioned oil sand slurries
Inventor: CYMERMAN GEORGE
IPC: B04C3/06
Filed: 1998-09-08
Abstract: A large capacity cyclonic separator is used for desanding a conditioned aqueous oil sand slurry comprising aerated bitumen, water and sand to produce pumpable, pipelineable lean froth and sand tailings. The cyclone separator is a vessel which forms an elongated cylindrical separation chamber and has a tangential slurry inlet at one end and, at the opposite end, a peripheral sand removal outlet and a centrally positioned vortex finder. Oil sand slurry is continually tangentially introduced into the cyclone separator to form a rotating vortex, which generates a centrifugal force. The lean froth migrates to the center of the vortex to form an inner core and is removed via the vortex finder. The sand tailings migrate to the outer reaches of the vortex and are co-currently removed via the sand removal outlet.

Abstract: The present invention is related to a light transmission type powder and granular measuring apparatus. The apparatus is comprised of two pieces of piping connected in such a manner to so as to branch the powder and granular material flowing line into two directions at a divergence point and to join again at a confluence point. A valve is installed at the divergence point. The valve is adapted to be switched to allow the powder and granular material to selectively flow in either one of the two pieces of piping. A light transmission type cell is mounted in at least either one of said two pieces of piping, wherein both the condition in which the powder and granular material is allowed to flow in the cell and the condition in which the powder and granular material is not allowed to flow in the cell can be accomplished by switching the valve without stopping the flow of the powder and granular material.

Title: Fluid extraction of metals or metalloids
Inventor: LIN YUEHE
IPC: B09B3/00
Filed: 1997-07-25
Abstract: Methods for extracting metalloid and metal species from a solid or liquid material by exposing the material to a fluid solvent, particularly supercritical CO2, and a chelating agent is described. The chelating agent forms a chelate with the species, the chelate being soluble in the fluid to allow removal of the species from the material. In preferred embodiments the extraction solvent is supercritical CO2 and the chelating agent comprises an organophosphorous chelating agent, particularly sulfur-containing organophosphorous chelating agents, including mixtures of chelating agents. Examples of chelating agents include monothiophosphinic acid, dithiophosphinic acid, phosphine sulfite, phosphorothioic acid, and mixtures thereof. The method provides an environmentally benign process for removing metal and metalloids from industrial waste solutions, particularly acidic solutions. Both the chelate and the supercritical fluid can be regenerated and the contaminant species recovered to provide an economic, efficient process.

Inventor: SANKEY JOHN PHILLIP
IPC: C07C409/24
Filed: 1997-12-16
Abstract: L'invention concerne des solutions acides aqueuses dont la stabilité est maintenue pendant le stockage. Ces solutions présentent souvent une valeur de pH pouvant atteindre 1, et contiennent un peracide d'ester et/ou un peracide d'acide. Elles peuvent être obtenues en faisant réagir un diester correspondant à la formule générale R<1>-O-CO-R<2>-CO-O-R<3>. Dans cette formule, R<1> et R<3> représentent chacun un groupe alkyle contenant 1 à 4 atomes de carbone qui peuvent être les mêmes ou différents, et R<2> représente un groupe alkylène aliphatique éventuellement non saturé qui peut être linéaire ou ramifié, contenant 2 à 6 atomes de carbone avec du péroxyde d'hydrogène aqueux en présence d'un acide, tel que de l'acide sulfurique, et permettant à ces compositions de progresser vers des concentrations d'équilibre. En commençant avec un diester, la perhydrolyse génère un peracide d'ester qui est un peracide particulièrement efficace. Ce procédé peut être contrôlé pour produire des solutions dont la teneur en peracide est élevée et qui présentent une large plage de rapports de peracide d'ester sur peracide d'acide.
Patent CA-2280861-A1 (CA)
Title: Valve mechanism for damping system
Inventor: TURNER PAUL H
IPC: F16F9/44
Filed: 1998-12-16
Abstract: A suspension system (12), particularly for a pedal-driven vehicle, comprising a telescoping strut having first and second telescopingly and coaxially engaged members (16, 18), and having a damping system (10) comprising a damping fluid (52), a damping piston (40) connected to a piston rod (30), an inertia-activated compression fluid flow control mechanism (79) and a pressureactivated compression fluid flow control mechanism (70) disposed in the first telescoping strut. The inertia-activated compression fluid flow control mechanism comprises a valve body biased by a valve spring (86) into a first position over a radial groove (94) formed on the piston so that the valve body prevents fluid flow through an inertia-activated compression fluid flow circuit in response to force inputs imparted to the vehicle frame. The valve spring (86) and valve body are connected to the piston rod (30) which extends into the first telescoping member (16) and is attached to the vehicle wheel, such that the valve body may be moved into a second position permitting fluid flow through the inertia-activated compression fluid flow circuit by force inputs imparted to the vehicle wheel. Because the inertia-activated fluid flow control mechanism is inertia-activated and not pressure-activated, a force impact imparted to the vehicle wheel results with fluid flow through both the pressure-activated and inertia-activated flow circuits, whereas force inputs such as from pedalling, weight shifting and acceleration or deceleration forces do not result in flow through the inertia-activated circuit. The suspension system therefore resists the absorption of pedal drive energy, provides a ride-leveling effect, and provides a broad range over which the damping system may be adjusted.

Abstract: An improved catalyst for the production of tube oil blending components, and lobe oils, from waxy, paraffinic feeds, a process for producing such catalyst, and a process utilizing this catalyst in the production of lobes. The catalyst is a unitized mixed powder pellet catalyst constituted of a dehydrogenation component, or components, suitably a catalytically active Group VIB, VIIB, or VIII metal, or metals, an isomerization component, suitably an amorphous acidic solid support, and a small pore molecular sieve dewaxing component. The dewaxing component is characterized as a small pore molecular sieve wherein the pore windows are formed by 8 oxide atoms which form the limiting edge of the pore window, each of the oxide atoms constituting one of the four oxide atoms of a tetrahedrally coordinated cluster around a silicon or aluminum framework ion, or atom, each oxide ion is coordinated to two framework ions in these structures, and the pore size of the sieve ranges between about 6.3 .ANG. and 2.3 .ANG..  In preparation of the catalysts, the isomerization component, or the dewaxing component or both, may provide the dehydrogenation function due to the presence of a catalytic metal, or metals, deposited thereon, in which case the components are powdered, the powders mixed together, compressed and formed into solids catalyst shapes comprised of these components. Alternatively, the dehydrogenation function can be added to preformed solids shapes made from powdered dewaxing and isomerization components.

IPC: G06T7/60
Filed: 1998-03-30
Abstract: Ce système vidéo est capable de tracer et d'extraire des objets dans les bords de sélection d'une image de l'objet à tracer sur la base d'un calcul de coûts de bord et de la quantité de rotation du bord. Le procédé de calcul des coûts de bord module l'ampleur en gradient du pixel par rapport au sens du gradient d'un bord de façon à réduire l'ambiguïté que l'on rencontre fréquemment pendant le tracé, sous forme de résultat, du bruit de fond de l'image. L'invention concerne également un procédé d'édition et d'amélioration du tracé consistant à introduire des points de contrôle entre des points préalablement générés dans le tracés. Etant donné que ses critères de sélection présentent une cohérence de bords pour une quantité de rotation d'un bord, on conserve au bord ses caractéristiques antérieures, et il n'y a plus besoin de traitement d'édition par itération. Du fait que les critères de sélection sont basés sur une rotation du trajet, on peut conserver une rotation du trajet qui ne nécessite qu'un minimum de surcroît de calcul.
