Filed: 2003-05-12
Abstract: New triterpenoid derivatives with various substituents at the C-17 position of 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO) were synthesized.  Among them, 2-cyano-3,12-dioxooleana-1,9(11)-dien-28-onitrile (CNDDO), 1-(2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl) imidazole, 1-(2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl)-2-methylimidazole, 1-(2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl)-4-methylimidazole show extremely high inhibitory activity (IC50 = 0.01-1 pM level) against production of nitric oxide induced by interferon-.gamma. in mouse macrophages. These compounds can be used in the prevention or treatment of diseases such as cancer, Alzheimer's disease, Parkinson's disease, multiple sclerosis, rheumatoid arthritis, and other inflammatory diseases.

Title: Systeme de neutralisation de l'eau de lavage d'une chaine de production de verre
Inventor: MAGER MICHAEL V
IPC: C03C25/14
Filed: 2003-05-12
Abstract: L'invention porte sur un système de neutralisation régulant le pH de l'eau de lavage servant au nettoyage et à l'entretien des équipements de production d'éléments de verre liés par des résines polyacryliques. Ledit système (62) de neutralisation introduit une solution basique (64) dans la solution d'eau de lavage circulant dans un système (12) de récupération d'eau de lavage en circuit fermé lorsque son pH tombe au-dessous de la plage d'environ 8,0 à 8,5. Il en résulte une réduction notable de la corrosion des pièces des équipements en contact avec les liants (18) acides d'acide polyacrylique. On peut également ajouter facultativement un co-liant d'acide maléïque ou d'anhydride maléïque à la solution de lavage. On peut en outre prévoir un système (100) de récupération à trémie en plus du système en boucle fermée permettant de récupérer et réutiliser le liant d'acide polyacrylique et le co-liant d'acide maléïque ou d'anhydride maléïque avec une quantité minimale de solution basique ce qui réduit la dégradation des propriétés isolantes des produits de fibres de verre liées par de l'acide polyacrylique.

Title: Methods and apparatus for polarization control
Inventor: ZHANG HONGBIN
IPC: G02B26/00
Filed: 2005-03-10
Abstract: Methods and apparatus of performing polarization control for optical transmissions are provided. The methods and apparatus enable polarization control devices to achieve a desired output state of polarization regardless of the input state of polarization. The desires state of polarization can be achieved by rotating waveplates in a polarization controller in a sequential fashion. Each waveplate may be continually adjusted or dithered so long as the feedback signal satisfies a feedback condition. Once the feedback signal exceeds the feedback condition, the next waveplate in the polarization controller is adjusted. This enables the methods and apparatus to rapidly adjust the state of polarization away from dead spots and minimize loss control problems.

Patent CA-2516715-A1 (CA)
Inventor: FULTON JOHN ROBERT LEWIS
IPC: F04D29/56
Filed: 2003-12-30
Abstract: An impeller pump with thermostatically adjustable swirl-vanes, in use as an automotive engine-driven coolant pump. Flow variation is controlled by varying the orientation of the swirl-vanes. A change in orientation is effected by a thermal driver, e.g a wax-type thermostat, which senses coolant temperature.  The swirl-vanes boost the flowrate when the coolant is hot, and decrease it when the coolant cools. The swirl-vanes are mounted for pivoting, and are located just upstream from the pump impeller. The traditional engine-thermostat function is provided inside the pumping-chamber, in that the swirl-vanes can be operated to close off a port to the engine radiator. The thermal driver opens the radiator-port as the coolant goes from Cold to Warm; as the coolant goes from Warm to Hot, the thermal driver operates the swirl-vanes from flow-reduce to flow-boost.

IPC: G01T1/169
Filed: 2005-08-19
Abstract: A portable survey instrument and methodology yield intensity of neutron radiation, intensity of gamma radiation, and a direction of impinging gamma radiation. The instrument uses a neutron detector surrounded by an essentially rectangular moderator with preferably four gamma ray detectors disposed symmetrically about the neutron detector and within the moderator. Material and dimensions of the moderator are selected so that the neutron measurement is equally sensitive to fast and thermal neutrons. The moderator also induces angular responses to the gamma ray detectors. Responses of the gamma ray detectors are combined to yield a parameter indicative of the angular position of a source. The survey instrument is portable and suited for hand held use.
