Title: Procede de lixiviation de chalcopyrite
Inventor: VAN DER MERWE CHARMAINE
IPC: C22B15/00
Filed: 1997-03-03
Granted: 2005-04-05
Abstract: L'invention concerne un procédé de lixiviation du cuivre contenu dans la chalcopyrite au moyen d'un sulfate ferrique. Des taux acceptables de lixiviation sont obtenus par la régulation des conditions permettant de maintenir le potentiel de la surface de la chalcopyrite dans une plage comprise entre 350 et 450 mV en fonction d'une "fenêtre" de variation empiriquement déterminée. L'efficacité du procédé dépend de la sélection dudit potentiel de surface; de la température de lixiviation; du pH de la solution de lixiviation et du degré de mouture de la chalcopyrite. L'invention peut être utilisée lors de procédés de lixiviation par cuve et lixiviation par tas.

Title: Durcisseurs a base d'oxazolidine destines au durcissement de resines resorcinoliques pour le collage d'articles en bois
Inventor: WU GAOMING
IPC: C08G14/02
Filed: 1998-03-25
Granted: 2004-08-03
Abstract: L'invention concerne un durcisseur à base d'oxazolidine amélioré, destiné à s'utiliser avec une résine résorcinolique ou une résine à base de tanin comme adhésif utilisé dans le collage d'articles en bois. De préférence, une oxazolidine est combinée à une base telle que NaOH et à un absorbant en poudre tel que de la farine de blé. L'adhésif à base de durcisseur amélioré peut s'utiliser pour coller des particules de bois afin de répondre aux exigences de résistance à l'état humide, après durcissement de la colle à une température ambiante pendant moins de 24 heures. La composition de durcissement améliorée est stable au stockage et peut être préparée à n'importe quel moment avant son utilisation, ce qui élimine la nécessité de préparer un durcisseur immédiatement avant l'utilisation de la colle. Puisqu'il est exempt de formaldéhyde, le durcisseur élimine les problèmes de sécurité liés à la manipulation de formaldéhyde ou de paraformaldéhyde. De même, le durcisseur possède un temps de gélification et une durée d'emploi flexibles. Puisque les résines peuvent durcir à température ambiante, le chauffage dans un four n'est pas nécessaire mais on peut y avoir recours pour réduire le temps de durcissement. L'utilisation de radiofréquences pour durcir les résines permet de réduire le temps d'exposition.

Title: Appareil de chauffage portable a element de chauffage catalytique dote d'un systeme d'allumage ameliore
Inventor: BONNEMA JAMES V
IPC: A45D1/02
Filed: 1998-03-17
Granted: 2004-11-09
Abstract: La présente invention concerne un dispositif de chauffage catalytique portable. Le dispositif comprend une structure de support de catalyseur, destinée à brûler un combustible gazeux ou liquide sans flamme, et à fournir, ainsi, une source de chaleur à une température inférieure à celle d'une source de chaleur qui brûle du combustible à l'aide d'une flamme. Le combustible est enflammé à l'intérieur la structure de support catalytique par une électrode à étincelle. L'allumage du combustible à l'intérieur de la structure évite d'avoir à recourir à des moyens pare-flammes séparés. Le système d'allumage comprend un dispositif piézo-électrique qui provoque la formation d'un potentiel de tension entre l'électrode et la structure de support catalytique. Une étincelle jaillit de l'électrode vers une surface intérieure de la structure et enflamme le combustible à l'intérieur de ladite structure, amenant une flamme à se propager. La flamme chauffe la structure catalytique à une température d'activation, puis le combustible est brûlé sans flamme sur la surface de la structure catalytique.

Title: Satellite communication routing arbitration techniques
Inventor: WONG ROLAND Y
IPC: H04Q3/66
Filed: 2000-01-12
Granted: 2002-09-17
Abstract: A satellite communication system which performs switching on data cells. A switch (80) receives the data cells at a set of input ports (IP1-IP128) and directs them to a set of output ports (OP1 - OP128). In order to arbitrate input data cells contending for the same output port, decision factor codes and routing codes are serially conducted to input registers (210), and a pseudo-random sequence code is appended.    The combined codes are ordered by routing code in a decoder (220). The code with the highest decision factor code is selected in one or more determinators (230 and 240). The selected code is identified by a bit in a result register (250).

Abstract: A system for producing prints of a professional motion picture film by dye transfer, including a roll tank (42), a pin belt (70), and a transfer cabinet (48). A dye imbibed matrix film (14) and blank film (12) are superimposed together in a predetermined registration by rollers (56-64) in the roll tank, creating a two-film sandwich (16), which is directed onto the pin belt (70). The pin belt (70} includes a plurality of pins (71) traveling in an orbital path (72), which detachably engage the two-film sandwich (16), thereby directing the two-film sandwich (16) along a portion of the orbital path (72). The transfer cabinet (48) includes a plurality of relatively large diameter rollers (86-92) in a predetermined relationship to one another, and an elevator mechanism for adjusting the predetermined relationship. The rollers (86-92) define a substantially rectilinear film path along which the two-film sandwich (16) from the pin belt (70) is directed. The film path (94) has a length sufficient to allow complete dye transfer to occur at high drive speeds within the transfer cabinet (48). The two-film sandwich (16) is then stripped apart. The blank film (12) may be directed through three dye transfer systems in a continuous path, a single color dye being applied by each system to produce a three color finished print.

Abstract: A combined sliding and pivot window assembly including a plurality of sashes separately pivotally mounted on substantially C-shaped sash support frames that are slidably fixed on rails provided on an outer window frame. The window assembly includes combined sliding and locking mechanisms that allow the C-shaped sash support frames to slide on the rails when the sashes are pivotally closed, or to be locked on the rails when the sashes are pivotally opened, or to be pushed to one side in the outer window frame while allowing all the sashes to be pivotally opened; pivot mechanisms that allow the sashes to be pivotally opened and stay at any desired open position relative to the sash support frames; and elastic two-end locking mechanisms that are mounted in a vertical member of the sashes to lock the sashes at upper and lower ends to the sash support frames simply by laterally shifting an external adjusting key of the two-end locking mechanism. The combined sliding and pivot window assembly is therefore safer and more convenient for use.

Abstract: A customer data capture system integrated with a dealership data management system allows customer and vehicle maintenance data to be exchanged between a kiosk on the floor of the dealership and the data management system. The customer inserts a customized card into a kiosk, and interacts with the pre-programmed software on the kiosk. The software recommends scheduled maintenance services and suggests potential coupon savings, based on the information received from the customer's card and the information stored in the data management system. A service order is generated and routed to the service department. As a result, the accuracy and speed of entering customer data are enhanced, while the dealership is able to offer value-added services at the point of sale, thus enhancing the dealership's business relationship with the customer.

Granted: 2004-11-09
Abstract: Door system for a transit vehicle having a vehicle body with a full height door opening, which is for alternatively boarding from ground level and boarding from a platform.      The transit vehicle has a floor, a stairway for ground level boarding and a trap door positionable in a deployed position for covering the stairway for platform boarding. The trap door is also positionable in a stowed position not covering the stairway for ground level boarding. The door system has a full height sliding door for covering and uncovering the door opening, and a threshold which is disposed within the sliding door when the sliding door is closed. The threshold is positioned at substantially the elevation of the floor.      A retention mechanism is attached to the threshold, the retention mechanism is activated when the trap door is in the deployed position to engage the trap door and release the sliding door so that when the sliding door is opened, the threshold is retained to fill a gap between the trap door and the platform. When the trap door is in the stowed position, the retention mechanism disengages the trap door and engages the sliding door so that the threshold moves with the sliding door and does not interfere with street level street level boarding.
