Patent CA-2250911-A1 (CA)
Inventor: WEIRICH ERICA E
IPC: C12Q1/02
Filed: 1997-05-07
Abstract: A rapid assay for infection in immunodeficient patients such as neonates (newborn infants) or immunocompromised patients (e.g. HIV or transplant patients) is used in diagnosis at initial evaluation, such that antibiotic treatment and confinement to an intensive care unit are avoided for uninfected patients. The assay can be used for detecting bacterial, viral, or fungal colonization of the blood stream, cerebrospinal fluid (CSF), or urinary tract.  The method is particularly suited for sepsis diagnosis. Polymorphonuclear leukocyte (PMN, neutrophil) CD11b (Mac-1, CR3) levels are measured by flow cytometry or laser scanning microscopy in low volume (0.1 ml) whole blood samples. A dual-laser FACS identifies neutrophils by FITC-conjugated anti-CD15 fluorescent antibodies, and identifies surface neutrophil CD11b marked with PE-conjugated anti-CD11b antibodies. Spontaneous upregulation of CD11b is prevented by handling samples at 4 ~C or adding a stabilizing compound such as anti-CD14 antibody or adenosine to the samples. A kit comprises calibration markers such as CD11b-coated microspheres for calibrating the device used for analysis according to diagnosis threshold(s), as well as fluorescent anti-CD11b and anti-CD15 antibodies.
Patent CA-2255287-A1 (CA)
Inventor: AHMED SHAMSUDDIN
IPC: C04B28/00
Filed: 1998-12-11
Abstract: A novel process of capturing and utilization of carbon dioxide from flue gases as a method of reducing the level of carbon dioxide emissions into the atmosphere is disclosed. The carbon dioxide is first chemically captured directly from the emission stream and then transformed into valuable commercial commodities. The capturing process comprises in passing the stream of flue gas through a reactor packed with a bed of capturing agent selected from the group consisting of calcium hydroxide, magnesium hydroxide, iron hydroxide and combinations thereof, at a temperature from about 200° C to about 400° C, a pressure of about 1 atmosphere to about 10 atmosphere and gas hourly space velocity from about 1000 h-1 to about 10,000 h-1. If desired, CO2 from the flue gas stream can first be separated by a membrane separator and then reacted with capturing agent. The said calcium hydroxide and magnesium hydroxide as capturing agents are synthesized from the group of abundantly available materials consisting of chloride salts of calcium and magnesium of sea water, fluorite/fluorspar (CaF2) mineral and apatite/rock phosphate (impure Ca3(PO4)2) mineral. Iron hydroxide in ferrous form as capturing agent is synthesized from haematite ore of iron present in abundance in earth's crust. The process of transforming the chemically captured carbon dioxide to valuable products is carried out by mixing the said chemically captured CO2 material with a suitable binding agent to form a plastic-like substance which is then compression molded in a pellet press or in an extruder to form mechanically strong, thermally stable and environmentally friendly articles of desired shapes and sizes having numerous potential domestic and engineering applications, enabling a permanent fixation of carbon dioxide.

Abstract: A method of making a multi-layer laminated shingle, in which a sheet of roofing material is cut into four strips, namely a shim strip, a first narrow tooth strip, a wide tooth strip, and a second narrow tooth strip, all dovetailing with each other. The shim is then laminated below the wide tooth strip to produce a first lamination. The first lamination is slit lengthwise along its centre to produce two half first lamination strips.      Each half first lamination strip is then laminated below a narrow tooth strip to produce two three layer lamination strips which are cross-cut into shingles. This enables production of a three layer laminated shingle simply and efficiently. In a modified method, two shim strips are used, one at each side of the sheet of roofing material, each being laminated below the wide tooth strip to produce a first lamination as before.

Abstract: Similar linear or dotted line-like grooves and/or heat-affected layers that remain even after stress-relief annealing are formed on both surfaces of a grain-oriented electrical steel sheet at the exact same positions or slight deviate positions by laser irradiation. Deviation of the formation positions on both surfaces is smaller than the width of the grooves and/or the heat-affected layers in a rolling direction, and the groove depth of the grooves on both surfaces is not greater than 5% of the sheet thickness. The steel sheet can be applied to both a wound core and a stacked core, and has excellent magnetic properties capable of reducing the load on production setups.
