Filed: 2001-01-08
Abstract: L'invention concerne un réservoir intermédiaire doublé d'aluminium ou de plastique contenant 50 à 1250 barils et destiné au mélange d'hydrocarbures avec du peroxyde d'hydrogène. La plate-forme supérieure de ce réservoir comporte un système de distribution du peroxyde d'hydrogène vers l'hydrocarbure qui se trouve dans le réservoir, comprenant un mélangeur à surface non réactive monté sur cette plate-forme pour mélanger le produit pétrochimique avec le peroxyde d'hydrogène. Une réaction d'oxydation entre le combustible et le peroxyde d'hydrogène a lieu dans ledit réservoir, qui comprend les éléments suivants : une couverture intégrale et des parois partiellement ouvertes au-dessus du niveau du combustible pour l'aération et l'accès du personnel ; un fond incliné où le produit après réaction (matière résiduelle) séparé du combustible peut se déposer ; une alimentation en eau sous forme d'une ouverture ou d'un tuyau de 2 à 4 pouces traversant la couverture ou un côté. Sur un côté à l'intérieur et au fond du réservoir se trouve un robinet qui peut être ouvert de l'extérieur, le sous-produit de l'oxydation étant lavé dans des fûts ou passant dans une colonne de stripping H2S standard et dans un appareil de piégeage du méthane, et ce, en faisant appel soit à un flux d'eau existant à l'intérieur du réservoir, soit à un nettoyage par ventilation pendant le traitement du combustible. Ce dispositif comprend également un procédé pour séparer les substances toxiques que sont l'azote, le soufre, le méthane, les métaux fins et les particules de carbone du combustible avant son utilisation à des fins commerciales au stade final, procédé selon lequel un lit de traitement au permanganate se trouve en aval du réservoir. Les combustibles pouvant être traités dans ce réservoir intermédiaire sont l'essence ordinaire, tous les types de gazoles, le kérosène, le carburéacteur et le carburéacteur liquide.

Title: Systeme et un procede de mesure du pied
Inventor: DOWDELL MARK
IPC: A43D1/02
Filed: 2002-04-30
Abstract: L'invention porte sur un système et un procédé de mesure du pied permettant de choisir des chaussures adaptées. Ledit système utilise un ordinateur qui comporte un programme d'adaptation recevant les mesures du pied ainsi que les caractéristiques de chaussures provenant d'une base de données ad hoc, et qui les compare afin de déterminer un indicateur d'adaptation pour chacune des propriétés comparées. Les données relatives au pied et à la chaussure comprennent: la longueur, la longueur du métatarse, la largeur, et la largeur du talon. La longueur utile de la chaussure se calcule au moyen du programme en partant de la longueur, retouchée par plusieurs facteurs dont la hauteur du talon, l'épaisseur du collier, et la forme et la hauteur de la coquille. Le programme comporte également un indicateur du type de chaussette à porter avec la chaussure sélectionnée compte tenu de son épaisseur. Le système permet à un utilisateur de choisir une chaussure sans avoir à l'essayer. Les mesures du pied fournies au programme s'obtiennent à l'aide d'un abaque téléchargeables et imprimable via Internet ou à l'aide d'un scanneur. Si l'impression se fait à une mauvaise échelle le programme peut y remédier en indiquant les facteurs d'échelle horizontal et vertical utilisés pour l'impression.

Patent CA-2005865-A1 (CA)
Inventor: BROADBENT RONALD W
IPC: B05D7/14
Filed: 1989-12-18
Abstract: An autodeposition bath for coating steel and similar metals is operated initially with a low content of dissolved iron and at a high oxidizing potential. After the iron content has increased beyond a specific level, such as 1.5 g/l, the oxidizing potential is reduced. This permits continued satisfactory operation of the bath with lower rates of iron accumulation in the bath, so that the need for bath stabilization by removing dissolved iron is deferred.

Title: Method for applying a conductive trace pattern to a substrate
Inventor: CLOUTIER FRANK L
IPC: H05K3/10
Filed: 1990-04-18
Abstract: ABSTRACT     A fabrication method for applying electrically conductive circuit traces to a substrate is described. The method uses an ink composition which is applied to a selected substrate by an ink jet delivery system. The ink includes an adhesive in combination with other additives, including one or more solvents.  The ink is delivered by the ink jet system in a selected pattern, followed by the application of a powdered metal to the pattern which adheres to the adhesive in the ink. After the removal of excess powder, the substrate, pattern and powder are heated in an amount sufficient to melt the powder on the substrate.  This produces a pattern of conductive traces geometrically corresponding to the ink pattern initially applied to the substrate.

Title: Sedimentation control process
Inventor: GILCHRIST IAN C R
IPC: B01D21/00
Filed: 1990-06-19
Abstract: ABSTRACT            Sedimentation in an inherently colloidally stable mixture comprising a suspension of solids in a liquid is controlled by a five-step process. In the first step a mathematical model representing a relationship between certain parameters, namely area product, viscosity and a parameter related to zeta-potential, is created. In the second step, zones in the model  in which there  is undesirably high viscosity are identified. In the third step, a model sedimentation path which skirts the high viscosity zones is superimposed on the model.  In  the  fourth  step,  the  actual  mixture  under consideration is monitored during a sedimentation process to obtain actual measured values of any or all of the critical parameters. In the final step, the parameters are adjusted as necessary to fit actual measured values to values on the model sedimentation path.

Patent CA-2028001-A1 (CA)
Title: Tool chuck
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/173
Filed: 1990-10-18
Abstract: A tool chuck according to this invention com-prises a locking device disposed between a chuck body and chuck claws slidable by screw feeding.  The lock-ing device presses and locks to the chuck body by a reaction force occurring when the chuck claws clamp a tool.  The tool chuck further comprises a torque amplifying device disposed between the locking device and a control ring rotatably mounted on the chuck body.  When the locking device is locked to the chuck body, the torque amplifying device reduces rotation of the control ring to output an amplified torque to a screw ring which screw-feeds the chuck claws.  The chuck claws are slidable fast until the chuck claws clamp a tool inserted in position to realize a quick clamping action.  When the chuck claws contact and hold the tool, the chuck claws are slidable with an increased torque, thereby holding the tool with a strong clamping force.

Title: Method to improve well performance in gravel packed wells
Inventor: JENNINGS ALFRED R JR
IPC: E21B43/04
Filed: 1990-11-29
Abstract: ABSTRACT        A method to improve well performance in gravel packed wells.  In this method a wellbore is perforated with four to twelve shots per foot.  Thereafter, hydraulic fracturing is conducted in the formation via a viscous fracturing fluid, having a 20/40 mesh proppant therein, which creates and props a fracture.  Hydraulic fracturing is ceased and a gravel pack is placed in the wellbore.  The gravel pack contains gravel of a mesh smaller than the fracturing fluid proppant, e.g. 40/60 mesh. The larger mesh proppant in the fracture forms a screen which prevents entry of most fines or sand into the fracture while the smaller mesh proppant removes fines or sand escaping the fracture screen.  Therefore, this combination removes substantially all fines or sand from hydrocarbonaceous fluids produced to the surface.

Title: Containers
Inventor: ANDREW REX
IPC: B65D77/04
Filed: 1991-01-28
Abstract: Containers have an outline in underneath plan view which is wedge shaped.  The wedge has a length greater than its width at the thicker end.          The containers are packed on a rectangular floor area, which may be the base of a box, with at least some containers in pairs side by side touching each other but with their wedge shapes oriented oppositely so that the thinner end of each wedge shape is adjacent the thicker end of the wedge shape of the other container of the said pair, but with a gap between the thinner end of each wedge shape and a notional rectangle whose sides are parallel to or coincide with sides of the rectangular boundary, and which fits around the wedge shapes with one pair of sides contacting the non-touching sides of the wedge shapes and the other pair of sides contacting the thicker ends of the wedge shapes.          This gives flexibility in fitting the containers onto a floor area, and in turn gives greater freedom of choice when designing packaging for a product.
