Patent CA-2275749-A1 (CA)
Inventor: LAJOIE GILLES M
IPC: B01F7/00
Filed: 1999-06-15
Abstract: Dans l'industrie de l'agitation d'un fluide, il existe quelques mécanismes pour assurer l'étanchéité d'un fluide à l'intérieur d'un réservoir muni d'un agitateur Cette étanchéité est nécessaire pour les opérations de maintenance sur le joint d'étanchiété mécanique ou la bourrure (ce qui assure l'étanchéité lorsque l'agitateur est en marche). Pricipalement on retrouve un system à sac gonflable qui, lorsque gonflé retient le fluide à l'intérieur. Un autre mécanisme utilisé est le "Jack Shaft". Ce mécanisme est actioné par un mouvement latéral de l'arbre de l'agitateur. Ce mouvement referme une plaque contre l'intérieur du réservoir et empêche le fluide de s'échaper. Dans la présente invention, le mécanisme consiste simplement d'une pair de mâchoires (en section de cercle) contenu dans un boîtier d'acier inoxydable en forme de disque. Le boîtier est conçu pour permettre un mouvement de translation des mâchoires. Ces mâchoires, faites d'un matériau de type "teflon" et usinées aux dimensions requises, s'accotent sur l'arbre de l'agitateur et empêchent le fluide dand le réservoir de s'échaper le long de l'arbre. De plus, le boîtier est muni de joints d'étanchéité statiques ("O-Rings") pour empêcher que le fluide s'écoule de par et d'autre des mâchoire (ceci quand tes mâchoires sont "engagées" (contre l'arbre) ou "déengagées"  (retirées)). Ce mécanisme fait appel à des concepts mécaniques communs, une géométrie simple (compacte) et des matériaux standards (acier inoxidable) et avancés (teflon). Un tel mécanisme permet une installation et un fonctionnement facile dû à ça géométrie simple, en plus d'un entretient peu couteux grave aux matériaux utilisés.

IPC: G01N27/90
Filed: 1999-08-03
Abstract: A signal processing apparatus includes a 2-dimensional conversion processing section, a 2-dimensional emphasis and attenuation processing section and a 2-dimensional smoothing processing section. The 2-dimensional conversion processing section maps an observation signal in a first coordinate system into a second coordinate system to output a 2-dimensional converted signal. The observation signal includes a detection object component and a noise component to be attenuated, and the noise component is composed of a first noise component and a second noise component. The 2-dimensional emphasis and attenuation processing section attenuates the first noise component to emphasize the detection object component and outputs a 2-dimensional filtered signal in which the detection object component is emphasized. The 2-dimensional smoothing processing section attenuates the second noise component contained in the 2-dimensional filtered signal, and outputs a 2-dimensional smoothing signal, whereby a detection object can be detected based on the 2-dimensional smoothed signal.

Title: Minimization of malodorous gas release for a cellulose pulp mill feed system
Inventor: LEBEL DAVID J
IPC: D21C/
Filed: 2000-01-26
Abstract: The release of malodorous TRS-containing gases from a comminuted cellulosic fibrous material feed system for a digester is minimized utilizing a particular arrangement associated with a pressure isolation device. Material is fed through the pressure isolation device and the pressure of the material increases from the inlet to the outlet, and the material is discharged from the pressure isolation device into a treatment vessel, such as a horizontal steaming vessel. Malodorous gases from the pressure isolation device are discharged substantially independently of the material discharged from the isolation device, and at least some of the malodorous gases discharged from the pressure isolation device are pressurized (e.g. in an eductor or thermocompressor) and reintroduced into the flow of cellulosic material downstream of the pressure isolation device (for example into the horizontal steaming vessel or a vessel downstream of it). In the horizontal steaming vessel the gases can be removed from a top portion thereof and fed to an NCG  system associated with the pulp mill.

Title: Process for removing nox and sox from exhaust gas
Inventor: SKELLEY ARTHUR P
IPC: B01D53/60
Filed: 2000-03-13
Abstract: An exhaust gas stream containing oxides of nitrogen and sulfur from a fossil fuel fired boiler, a fired process heater, or a chemical process are diverted from a stack prior to emission to the atmosphere through a duct system to a mixer where an oxidant, such as ozone, is added to the exhaust gas at a preselected molar ratio for a preselected residence time to transform the oxides to higher order nitrogen oxides. The oxidized contaminants are treated with a reagent solution. The reagent solution absorbs the oxidized contaminants and unreacted oxidant in the exhaust gas stream. Nitrogen and sulfur oxides in the gas steam are transformed to dilute acids which are neutralized to form salts suitable for discharge to a municipal waste water treatment plant or landfill disposal. The salt solution is also useful as a fertilizer or in the manufacture of fertilizers. The treated exhaust gas is then emitted from an exhaust stack containing NO x and SO x contaminants at a ppm level meeting required air quality standards.
