Title: Treatment of water containing organic wastes with ammonium nitrate
Inventor: SAWICKI JOHN EDWARD
IPC: C02F1/74
Filed: 2001-07-03
Abstract: A single step wet oxidation process for treating wastewaters containing organic species, with or without heteroatoms, and anions of strong acids, e.g. sulfate or phosphate ion, or cations of strong bases, e.g., sodium, potassium or calcium ions, and which may contain ammonium ion and/or nitrate ion in addition to added ammonium ion and/or nitrate ion was developed which on thermal treatment near the critical temperature of water removes substantially all the COD and nitrogen through conversion to water, carbon dioxide or carbonate species, nitrogen gas and small amounts of nitrous oxide. Key to the success of the process is the balancing of all reducing species with an equivalent amount of oxidizing species and the balancing of all strong acid anions with strong base cations. The former ensures good removal of organic species, ammonium ion and nitrate ion. The latter ensures maintaining the pH in the range of from 1.5 to 8 thus avoiding severe corrosion problems and regions of pH where rate of reaction of the oxidizing species with reducing species is slow.

Patent CA-2356279-A1 (CA)
Inventor: LECHNER MORITZ
IPC: G01F1/696
Filed: 1999-12-08
Abstract: Selon l'invention, pour la mesure du flux massique d'un liquide ou d'un gaz, un élément chauffant (4) est disposé entre deux capteurs de température (5, 6). Le flux massique est déterminé à partir de la différence de température des capteurs de température (5, 6). Pour que la consommation en courant de l'appareil soit réduite, l'élément chauffant (4) est activé de façon impulsionnelle. On obtient une autre réduction de la consommation de courant grâce à un circuit de surveillance (12) qui ne met en circuit la partie de mesure (11) proprement dite que lorsque les signaux des capteurs de température (5, 6) remplissent une condition de seuil.

Patent CA-2364276-A1 (CA)
Inventor: KOTRE STEPHEN JOHN
IPC: B60K6/445
Filed: 2001-12-05
Abstract: The present invention provides a method and system for determining "engine on" status in a Hybrid Electric Vehicle.  A controller determines that the engine is necessary and then checks the current "engine on" status. If the engine is not currently running, the controller proceeds to start the engine by commanding the generator to spin or "motor" the engine.  The controller then starts fuel and spark within the engine to create combustion. Measuring devices are then used to determine the ion current/breakdown voltage across a spark gap in the engine. The controller receives this measurement and determines whether the measured ion current/breakdown voltage exceeds a calibratable threshold. If the calibratable threshold is exceeded, combustion is occurring and the engine is on. The controller then turns on the "engine on" status flag.

Title: Recombinant adenoviral vectors and their utilization in the treatment of various types of hepatic, renal and pulmonary fibrosis and hypertrophic scars
Inventor: ARMENDARIZ BORUNDA JUAN
IPC: C12N15/09
Filed: 2000-09-14
Abstract: The use of gene therapy for the treatment of different kinds of fibrosis in human beings is disclosed. The purpose is the use of "therapeutic"genes specifically directed to target organs to revert and/or prevent the development of the fibrosis process.   The potential application of gene therapy to patients with fibrosis and/or cirrhosis will depend to a large extent on the successful delivery of genes which encode for therapeutic proteins to livers with severe fibrosis and that these genes which encode for proteins human MMP-8 active and latent, MMP-1, MMP-2, MMP-9 and MMP-13; human uPA wild type and/or modified (or its truncated version), the truncated receptor for TGF-.beta. type II and Smad-7 can be-directed by adenovirus and/or other recombinant vectors that cannot transduce (infect) others organs.  The recombinant adenoviruses (AdR) are vectors highly efficient for the transduction of therapeutic genes to diverse target cells. We have proved that they can carry genes to cirrhotic livers.  The delivery of therapeutic genes through such adenoviral vectors and other recombinant vectors could also be performed using cationic and anionic liposomes (DOTMA).   Therefore, we propose the use of this patent to be applied in the same manner to: *Renal fibrosis *Pulmonary fibrosis *Hypertrophic and keloid scars (skin fibrosis), and *Other kinds of fibrosis.
