Title: Machine de coulee en bande pour la production d'une bande metallique
Inventor: MARTI HEINRICH
IPC: B22D11/06
Filed: 2001-09-19
Abstract: L'invention concerne une machine de coulée en bande pour la production d'une bande métallique. Cette machine présente deux rouleaux de coulée (22, 24) juxtaposés, formant un intervalle de coulée (15'), présentant chacun une largeur de couverture et sur lesquels sont agencées des étanchéités latérales (25) côté frontal. Ces rouleaux de coulée sont montés rotatifs sur un montant de machine (32). Entre ces rouleaux et les étanchéités latérales (25), le métal liquide, pouvant être versé par au moins une busette de coulée (13) ou analogue, est protégé par au moins un milieu gazeux. Les rouleaux de coulée (22, 24) sont entourés par une enveloppe (30, 60, 80) de préférence à plusieurs compartiments, au moins le long de leur largeur de couverture, de leurs faces frontales ainsi que des étanchéités latérales (25). On obtient ainsi de manière simple une étanchéité optimale des rouleaux de coulée, tout comme du bain de métal et de la bande métallique sortant desdits rouleaux.

Title: Central vacuum with acoustical damping
Inventor: LAURITSEN STEVEN D
IPC: A47L9/00
Filed: 1996-11-22
Abstract: A central vacuum unit having an acoustic damping system is provided. The central vacuum unit includes a canister having a sidewall forming a hollow interior and a lid closing an end of the sidewall, a vacuum motor within the canister which emits noise during operation, at least one cooling air inlet for admitting cooling air into the hollow interior, and at least one cooling air outlet in the sidewall for exhausting the cooling air from the hollow interior. Additionally, the sidewall has an exhaust port and the motor has an exhaust pipe extending through the exhaust port. The acoustic damping system includes an acoustic damping tunnel, an acoustic damping canopy, and an exhaust port seal. The acoustic damping tunnel is within the hollow interior and forms a pathway between the hollow interior and the cooling air outlet. The pathway is lined with a sound absorbing material so that the tunnel reduces noise emitted from the hollow interior through the cooling outlet. The acoustic damping canopy is attached to the canopy over the cooling air inlet. The canopy has an inlet and forms a serpentine pathway between the canister cooling air inlet and said canopy inlet to reduce noise emitted from the hollow interior through the canister cooling air inlet. The exhaust port seal covers the exhaust port to reduce noise emitted from the hollow interior through the exhaust port. The exhaust port seal preferably includes flexible foam bonded to the canister sidewall.

Title: Hypertext-based system and method for knowledge editing
Inventor: BEDJANIAN GENNADI
IPC: G06F17/24
Filed: 2003-12-19
Abstract: A system, which is a bona fide knowledge editor, provides a tool for projecting knowledge into hypertext, modifying it, and returning it to human memory, with an option of storing projections on data carriers. Hypertextual knowledge representation is created and manipulated via a knowledge model in a hypertext editing window. Knowledge elements are created directly in the hypertext editing window or dragged into it as words and phrases from an optional text window. Properties are assigned automatically to graphical elements and their respective nodes or links in the internal model of hypertext. Ease of use and background XML encoding make the system accessible to any computer user. The system and method facilitate thinking and learning, allow to create simple and sophisticated ontologies, concept maps, domain knowledge models, other semantic artifacts, and also to merge models produced by many authors into averaged semantic representations ready for further use in Semantic Web.
Patent CA-2452689-A1 (CA)
Inventor: PRIDE THOMAS E
IPC: B65D85/48
Filed: 2003-12-09
Abstract: A clamping cartridge is provided which comprises a plurality of clamping mechanisms spaced apart on a frame or chassis. The clamping mechanisms are generally oriented perpendicular to their direction of spacing. The clamping mechanisms are of the type which comprise a pair of relatively movable jaws which are biased together. An actuator operable in association with the clamping mechanisms serves to open and close the jaws of the clamping mechanisms in unison. While the clamps are closeable in unison, they are individually self-adjusting so the extent of closure for each clamp is dependent on the thickness or presence of an inserted article. The clamping cartridges are useful in a variety of applications requiring clamping of one or more articles in a side-by-side relationship. One such application is a transportation/storage rack which includes a plurality of aligned horizontal and vertical clamping cartridges for clamping the edges of glass panels.

Patent CA-2462609-A1 (CA)
Inventor: JOHNSON KENNETH G
IPC: F04D25/04
Filed: 2002-10-09
Abstract: Pompe et système de pompage conçus pour extraire des liquides, du gaz, du sable ou des particules de charbon de puits de forage de gaz ou de pétrole depuis la proximité de la roche, à savoir, la zone de production. Cette pompe et ce système peuvent augmenter également l'utilisation d'installations de surface disponibles ou connues (compresseur ou séparateur ou ensemble compresseur et séparateur de surface). Il est nécessaire que l'industrie pétrolière développe une pompe présentant une efficacité accrue et capable de fonctionner dans des puits dont la pression en fond de puits n'est pas suffisante pour faire monter les liquides à la surface, ce qui rend difficile l'exploitation du puits et, en cas de manque de rentabilité, provoque son obturation potentielle prématurée. Cette pompe permettra aux producteurs de dépasser les possibilités actuelles d'extraction artificielle, par exemple, pompage, extraction hydraulique, extraction gazeuse ou piston. Cette pompe possède un fonctionnement sécurisé, économique et peut empêcher toute détérioration potentielle du puits de forage. Elle permettra, de plus, d'entretenir le puits de forage par lavage à l'acide afin de nettoyer les perforations et de traiter en continu la sédimentation. Ceci est du à l'absence de liquides, ce qui permet d'optimiser le contact des produits chimiques avec le rocher sans risque de dilution, et de presse-étoupe mécanique ou autres équipements placés à l'intérieur du puits (entre le tubage et les canalisations de production), entre la surface et le rocher, ce qui empêcherait les produits chimiques d'atteindre la surface rocheuse. On peut pomper ces produits chimiques afin de les introduire dans l'espace annulaire au moyen d'un camion-pompe et aucune autre opération ou aucun autre équipement n'est nécessaire pour les supprimer qu'un ensemble de nettoyage à grande eau. Ceci permet d'éliminer les coûts associés à un équipement mécanique servant à extraire le presse-étoupe ou à la suppression des liquides présents dans le puits de forage. Cette nouvelle pompe met en application l'énergie motrice du compresseur de gaz naturel en surface, qui introduit une quantité réglable de volume de gaz naturel (équivalente à la pression ou Psig) dans une turbine axiale ou une série de turbines afin de créer un couple correct et/ou obtenir le nombre de révolutions à la minute (RPM) nécessaire pour créer une aspiration au niveau de l'entrée de la pompe ou pour inverser le déplacement de la turbine axiale. Ce procédé permet à la pompe d'extraire des liquides, du sable, des particules de charbon ou du gaz hors du puits de forage sous l'effet d'un vide crée par la rotation de la turbine axiale inversée.
