Title: Object oriented method and system to draw 2d and 3d shapes onto a projection plane
Inventor: JAIN RAJIV
IPC: G06T19/20
Filed: 1997-06-18
Abstract: A computer method (500-570) draws overlapped two-dimensional shapes (A, B) and two-dimensional projections of three-dimensional shapes (C') onto a projection plane (102) in a system of world coordinates (X, Y, Z). The method instantiates a plurality of two-dimensional geometry class objects (320', 320"), each of which includes an order attribute (ORDER) specifying an overlapped position for depicting a corresponding two-dimensional shape (A, B) on the projection plane (102) positioned orthogonally to the Z coordinate of the world coordinate system. The method (500-570) instantiates a three-dimensional geometry class object (330', 330") including a Z-value (Z-value) for a position along the Z world coordinate of the three-dimensional shape (C'). The method sons the plurality of two-dimensional geometry class objects by their respective order attributes in a sorting table in the memory (510). The method sorts the three-dimensional geometry class object by its Z-value in the sorting table and orders it in a composite order with the two-dimensional class objects in the sorting table (520). The method then draws the two-dimensional shapes (A, B) and two-dimensional projections of the three-dimensional shapes (C') onto the projection plane (102) in the composite table (400) order, to depict an overlapped appearance of the shapes.

Title: Process for ethyl acetate production
Inventor: CHUANG KARL T
IPC: B01J31/08
Filed: 1997-11-07
Abstract: Oxidation of liquid ethanol in the presence of excess liquid ethanol and a supported oxidation catalyst provides a one step process for production of ethyl acetate. The acetic acid produced in the oxidation is absorbed by the excess liquid ethanol, which esterifies to ethyl acetate. Ethyl acetate and water is removed from the process for separation of the ethyl acetate. The oxidation portion of process is preferred with a metallic oxidation catalyst on a hydrophobic support and the esterification portion with an acidic solid ion exchange resin to promote the esterification. The process can be performed in series in separate steps, or preferably, in parallel in a single vessel, preferably a trickle bed reactor. The process is easily controlled and enables the use of a wide range of ethanol concentration as feed material.

IPC: A61K36/9066

Abstract: Jusqu'à ce jour tout le corps médical offciel mondial sait bien que la cause du cancer restait inconnue. Dans son Brevet Américain No 5,665,751 du 9 Sept. 1997 M.Camden a confirmé:"La cause exacte du cancer est inconnue". On a cherché à traiter le cancer par plusieurs moyens: Les produits chimiques anticancéreux très forts appelé chimiothérapie. Mais malheureusement cette thérapie est trop toxique pour le corps humain d'une part, d'autre les cellules cancéreuses deviennent très viterésistantes à cette chimiothérapie. Ainsi pour réduire ou inhiber la résistance des cellules cancéreuses et des microbes à l'égard de cette chimiothérapie et des antibiotiques, pour augmenter l'effet cytotoxique de cette chimiothérapie anticancéreuse et pour activer des macrophages, on a inventé des catalyseurs comme le "glucan phosphorulé solubre" (Brevet US No 4,761,402 de M. Williams et al) et le bloc copolymère polyéther (Brevet US No 5,817,321 de Alakhov, Valery Yu et al.). Pour inhiber la croissance des cancers, la prolifération des cellules cancéreuses et plus pratiquement pour inhiber l'angiogénèse dans l'anormale néovascularisation cancéreuse, on a inventé une classe d'antifongiques inhibiteurs Imidazoles ((Brevet US No 5,512,591 de Mr Halperin et al.), et d'autres antifongiques inhibiteurs comme 1,3-bis-triazolyl-2-propanol (Brevet No 5,665,751 of auteur Camden). Tous ces traitements pourraient prolonger plus ou moins la vie des cancéreux. En dehors de ces traitements, les interventions chirurgicales et la radiothérapie existent depuis longtemps. De plus on a fait une grande progrès dans la détection précoce et dans la prévention adéquate pour les cancers. Identifier exactement l'origine ou la cause ou la nature du cancer est sans doute un geste primordial, bien nécessaire et le plus utile pour une thérapeutique étiologique, radicale et rationnelle du cancer. Ma demande de Brevet d'invention est basée sur la découverte de l'identification du cancer et du virus (dans les maladies virales), c'est à dire basée sur leur nature ou leur origine. Car une fois la nature ou l'origine du virus et du cancer est connue, le traitement du cancer et des infections virales ne sera qu'une routine et la guérison définitive est sûre. Ainsi mon invention est une découverte originale. THIS PAGE DOES NOT BELONG IN THIS SECTION

Patent CA-2280072-A1 (CA)
Inventor: MA WEIJIAN
IPC: F16K17/00
Filed: 1999-08-11
Abstract: Apparatus for rapidly changing the state of a device from an active state to an inactive state. The apparatus includes an inner member slidably contained in an outer member. The member is connected to an actuator and the other to a control for changing the state of a device. A latch mechanism normally holds the two members locked together so that the control means responds to the actuator. When a potentially dangerous situation is sensed, the latch mechanism is opened and the two members are rapidly forced apart by a heavy release spring thus rapidly changing the state of the device from an active state to an inactive state.

Title: Ablation de la couche cornee au moyen d'une source de lumiere
Inventor: BOJAN PETER M
IPC: A61F9/007
Filed: 1998-03-20
Abstract: L'invention concerne un procédé pour améliorer la perméabilité de la couche cornée au moyen d'une source de lumière, de préférence, au moyen d'un laser, si possible d'un laser pulsé. En augmentant la perméabilité de la couche cornée, on ouvre l'accès au liquide interstitiel, ce qui permet de mesurer les analysats contenus dans le liquide interstitiel. Dans l'un des aspects, le procédé comprend les étapes qui consistent: a) à fournir une source de lumière possédant une longueur d'onde comprise entre environ 930 nm et environ 1040 nm; et b) à exposer une région de la couche cornée du patient à ladite source de lumière pendant une durée suffisante pour la formation d'une ouverture dans la couche cornée. De préférence, on fait cesser l'exposition de la région de la couche cornée à la source de lumière lorsqu'une quantité de liquide interstitiel remplit l'ouverture dans la couche cornée, ladite quantité étant suffisante pour faire en sorte que l'intensité de diffusion de la lumière réfléchie par la surface du liquide interstitiel, qui occupe l'ouverture dans la couche cornée, diffère de l'intensité de diffusion de la lumière réfléchie par une région de la couche cornée sensiblement exempte de liquide interstitiel. L'invention concerne également un appareil permettant la mise en oeuvre du procédé décrit.

Title: Drive and steer vehicle
Inventor: TEAL RICHARD DONALD
IPC: B62D11/18
Filed: 1999-09-29
Abstract: A vehicle such as a lawn and garden tractor is adapted to utilize conventional steering and propel controls with a drive and steer type transmission. The transmission permits the vehicle to be driven and steered through its rear drive wheels, thereby permitting it to turn about one wheel and/or about an axis between its wheels. Front castered wheels enable the vehicle to be easily steered by the drive wheels. A conventional type steering wheel is provided with a mechanical linkage extending between it and the transmission. Conventional type foot control pedals are also provided to propel or power the vehicle in a forward or rearward direction and within a range of speeds. With conventional type steering and propel controls adapted to be utilized with the drive and steer type transmission, operation of spin-turn vehicles is made simple and more efficient as well as reducing the time required to learn to operate and maneuver the vehicle.
