Jason Weiss, Edmonton CA

Patent application numberDescriptionPublished
20100037697PRESSURE SENSOR - An apparatus for sensing pressure is provided comprising a housing, electronics, a pressure sensor and a secondary seal. The housing comprises an interior bore and a first end, with the interior bore forming an opening at the first end. The electronics may be disposed in the interior bore. The pressure sensor is mounted at the first end of the interior bore. The pressure sensor may be operatively connected to send signals to the electronics in response to external fluid pressure. The pressure sensor may, at least in part, form a primary seal at the first end of the interior bore. The secondary seal may be disposed in the interior bore in between the pressure sensor and the electronics. The secondary seal may be configured to act as a backup seal to the primary seal. The secondary seal provides an added degree of safety from high pressure pipeline contents. The secondary seal also ensures that the important interior electrical components of the apparatus are not damaged upon failure of any component located at the first end. If the pressure sensor or primary seal is damaged, for example, a new pressure sensor or primary seal may be installed without having to replace the entire apparatus. The secondary seal also prevents fluid from a high pressure pipeline that has compromised the primary seal from being ejected from the pipeline. The secondary seal also prevents pipeline media from migrating through the electrical cable to a non-hazardous location.02-18-2010

Patent application numberDescriptionPublished
20120175315Process for Flocculating and Dewatering Oil Sand Mature Fine Tailings - A process for dewatering oil sand fine tailings is provided and comprises a dispersion and floc build-up stage comprising in-line addition of a flocculent solution comprising an effective amount of flocculation reagent into a flow of the oil sand fine tailings; a gel stage wherein flocculated oil sand fine tailings is transported in-line and subjected to shear conditioning; a floc breakdown and water release stage wherein the flocculated oil sand fine tailings releases water and decreases in yield shear stress, while avoiding an oversheared zone; depositing the flocculated oil sand fine tailings onto a deposition area to form a deposit and to enable the release water to flow away from the deposit, preferably done in a pipeline reactor and managing shear according to yield stress and CST information and achieves enhanced dewatering.07-12-2012

20120189575Oligodendrocyte Production from Multipotent Neural Stem Cells - This invention relates to methods of producing oligodendrocytes from multipotent neural stem cells by using at least one oligodendrocyte promoting factor, particularly granulocyte-macrophage colony stimulating factor, granulocyte colony stimulating factor, interleukin 3 or interleukin 5. The neural stem cells may optionally be expanded prior to being subjected to the oligodendrocyte promoting factor.07-26-2012

20090081205CONTINUOUS DOSING REGIMENS FOR NEURAL STEM CELL PROLIFERATING AGENTS AND NEURAL STEM CELL DIFFERENTIATING AGENTS - The present invention provides effective dosing regimes for neural stem cell proliferating agents, kits containing effective dosing regimes for neural stem cell proliferating agents, and uses thereof. In particular, neural stem cell proliferating agents, such as hCG, prolactin and EPO are delivered to mammalian subjects at low doses in a continuous fashion over several days, as opposed to delivery of high doses in a short period of time.03-26-2009
20090274668Combined Regulation of Neural Cell Production - This invention relates to a method of selectively producing neural cells, including neurons or glial cells, in vitro or in vivo. Also provided are methods of treating or ameliorating neurodegenerative disease or medical conditions by producing neural cells. Thus, a combination of factors is used to achieve two steps: increasing the number of neural stem cells and instructing the neural stem cells to selectively become neurons or glial cells.11-05-2009
20100113357Platelet-derived growth factor-responsive neural precursor cells and progeny thereof - This invention provides platelet-derived growth factor-responsive neural precursor (PRP) cells and methods of producing such cells in vivo or in vitro. These cells can further be used to generate neurons, oligodendrocytes and/or astrocytes.05-06-2010
20100135968Oligodendrocyte Production From Multipotent Neural Stem Cells - This invention relates to methods of producing oligodendrocytes from multipotent neural stem cells by using at least one oligodendrocyte promoting factor, particularly granulocyte-macrophage colony stimulating factor, granulocyte colony stimulating factor, interleukin 3 or interleukin 5. The neural stem cells may optionally be expanded prior to being subjected to the oligodendrocyte promoting factor.06-03-2010
20100239528Treating or Ameliorating a Neuroinflammatory or Demyelinating Disorder with Prolactin and Interferon-Beta - Methods, compositions and kits for treating or ameliorating a disorder associated with neuroinflammation or de-myelination in a mammal are disclosed. Said methods, compositions and kits comprise prolactin, a prolactin-inducing agent, or a variant, analog or functional fragment of prolactin in combination with interferon-β.09-23-2010
20110178009Pheromones and the Luteinizing Hormone for Inducing Proliferation of Neural Stem Cells and Neurogenesis - The present invention provides a method of increasing neural stem cell numbers or neurogenesis by using a pheromone, a luteinizing hormone (LH) and/or a human chorionic gonadotrophin (hCG). The method can be practiced in vivo to obtain more neural stem cells in situ, which can in turn produce more neurons or glial cells to compensate for lost or dysfunctional neural cells. The method can also be practiced in vitro to produce a large number of neural stem cells in culture. The cultured stem cells can be used, for example, for transplantation treatment of patients or animals suffering from or suspected of having neurodegenerative diseases or conditions.07-21-2011
20110182853PLATELET DERIVED GROWTH FACTOR (PDGF)-DERIVED NEUROSPHERES DEFINE A NOVEL CLASS OF PROGENITOR CELLS - The present invention is related to the discovery of a novel class of neural progenitor cells, which proliferate in response to platelet derived growth factor (PDGF) and differentiate into neurons and oligodendrocytes but not astrocytes. Progeny of the progenitor cells can be obtained by culturing brain tissue in PDGF without serum, epidermal growth factor (EGF), fibroblast growth factor 2, or transforming growth factor alpha. Upon subculturing into EGF-containing media, these progeny cells can proliferate and form neurospheres, whereas PDGF has no such effect.07-28-2011
20110269681Prolactin Induced Increase in Neural Stem Cell Numbers - The present invention provides a method of increasing neural stem cell numbers or neurogenesis by using prolactin. The method can be practiced in vivo to obtain more neural stem cells in situ, which can in turn produce more neurons or glial cells to compensate for lost or dysfunctional neural cells. The method can also be practiced in vitro to produce a large number of neural stem cells in culture. The cultured stem cells can be used, for example, for transplantation treatment of patients or animals suffering from neurodegenerative diseases or conditions. In addition, since neural stem cells are a source for olfactory neurons, the present invention also provides methods of increasing olfactory neurons and enhancing olfactory functions.11-03-2011
