Patent CA-2217093-A1 (CA)
Inventor: WERNER JEAN-JACQUES
IPC: H04L27/38
Filed: 1997-09-30
Abstract: A blind equalization technique uses both the "constant modulus algorithm" (CMA) and the "multimodulus algorithm" (MMA) during blind start-up.  This approach provides the basis for a "transition algorithm."  One example of a transition algorithm is the CMA-MMA transition algorithm in which an adaptive filter simply switches from CMA to MMA.  Other examples are variations of the CMA-MMA transition algorithm and are illustrated by the "Constant Rotation CMA-MMA" transition algorithm and the "Dynamic Rotation CMA-MMA" transition algorithm.

Patent CA-2228202-A1 (CA)
Inventor: NELSON WILLIAM ERNEST
IPC: B09B1/00
Filed: 1998-04-02
Abstract: Although we tend to envision the air we breathe to be clean, the industrial progress of our era has produced an array of invisible but highly hazardous pollutants that endanger our environment and jeopardize our health. ~ Mining and industrial operations involving large scale excavation and movement of soil, ash, dust and waste material unavoidably lead to significant impacts on the surrounding natural environment. ~ The most damaging impact of many mining operations is the exposure of minerals to the open air where they may become vulnerable to acidification and release harmful contaminants. This is commonly termed "acid mine drainage," which is the creation of acidic conditions through the exposure and oxidation of sulfide minerals at a mine site. Sulfide minerals and associated acidity can be found in many mine tailing components and industrial site wastes and tailings from mill processing. Acid mine drainage is also reported at many types of precious-metal, base-metal and uranium mines. ~ Fossil fueled industrial sites emit Fly and Bottom ash containing PAHs (poly-nuclear-aeromatic-hydrcarbons) that are radioactive. These are commonly disposed of being spread on the surface of fields, only to become airborne and leached into the ground water. Most of these sites are found near large cities. These particles have been identified as causing cancer, emphysema, and other related diseases when inhaled into the lungs. ~ Another example of air-soil-and water contamination is the results of the Chernobyl explosion. The radionuclides radioisotopes released rained down on the earth and will remain there for thousands of years to come. The soil is contaminated with deadly radioactive hot spots. If untreated they will transmigrate through the eco system and cause mass mutation to all forms of life. Radiotoxic elements like cesium-137, plutonium 239, americium 241, just to name a few of the many that spewed forth from the stricken reactor. They lay loosely on the land surface for miles surrounding Chernobyl. These radiotoxic materials are the most dangerous of the radioactive group. Soluble plutonium forms are deposited in the bones and americium is deposited in the bones and kidneys.  Acute damage is the result and short life duration is expected. These hot spots can be treated and stabilized and be prevented from leaching deep into the water table and from becoming airborne. ~ The dust of minerals, such as coal, being transported in open rail cars or trucks, which can prove harmful if allowed to become airborne and escape into the air and surrounding environs. This invention provides a reliable, durable method for stabilizing fly ash, crushed ore, mine tailings radioactive hot spots and industrial waste effectively preventing them from invading Earth's biosphere. The development and implementation of reliable environmental protection techniques will enhance industrial activity and environmental maintenance.:

Title: Molten metal admission control in casting
Inventor: SALEE DAVID ALAN
IPC: B22D11/103
Filed: 1996-08-16
Abstract: A method and apparatus to control the rate at which molten metal is initially fed to a plurality of continuous casting molds (20). Elevation sensors (102, 190) are suspended from beams (68) which in tum are suspended from an elongated rack (56). The sensors generate a signal used to control valve mechanisms (86). During the initial filling phase of the mold (20), the sensors (102, 190) are locked into an initial position in which molten metal is fed to the molds at a specific rate. When the molten metal in the individual molds reaches a specific intermediate level, triggers (66) are activated which allows the elevation sensors (102, 190) to assume control of the rates at which molten metal is fed to the molds. The elevation sensors (102, 190) control the height of the metal columns in the molds at a constant height with respect to the position of the elongated rack (56). After a period of time in which the height of molten metal in the individual molds (20) have established equilibrium, the elongated rack (56) is elevated at a controlled rate to an operating position. In turn, the molten metal in the respective molds is raised to an operating position at a controlled rate.

Filed: 1996-11-21
Abstract: Cette invention concerne des matériaux ferroélectriques utilisés en qualité de supports d'enregistrement holographique réversibles (25) dans des systèmes d'enregistrement à deux photons. Ces matériaux ferroélectriques permettent d'obtenir des états conducteurs électroniques de longue durée qui se situent entre les bandes de valence et de conduction du matériau ferroélectrique. Ces états intermédiaires possèdent une durée de vie suffisamment longue (de l'ordre de 1 à 100 millisecondes) pour pouvoir utiliser des lasers à onde entretenue et de faible puissance (1) afin d'y enregistrer des diagrammes d'interférence. Cette invention concerne également des systèmes d'enregistrement holographiques à deux photons qui ne nécessitent pas de recours à des lasers de grande puissance, à courte longueur d'impulsion, à modes bloqués, ou encore à des lasers déclenchés. Les systèmes d'enregistrement holographiques décrits dans la présente invention font plutôt appel à des lasers à onde entretenue visibles et proches de l'infrarouge, tel que des lasers à diode. Les systèmes d'enregistrement holographiques décrits dans la présente invention absorbent un premier photon qui va exciter les électrons des supports d'enregistrement holographique jusqu'à ce que l'on atteigne un état conducteur intermédiaire. Ensuite, après l'absorption d'un second photon, les électrons sont envoyés dans la bande de conduction des supports où ils sont disposés en fonction du diagramme d'interférences fourni par le système d'enregistrement.

Inventor: GRYAZNOV SERGEI M
IPC: C07H19/20
Filed: 1996-06-14
Abstract: The invention provides a method of synthesizing oligonucleotide N3'P5' phosphoramidates using an amine-exchange reaction of phosphoramidites in which a deprotected 3'-amino group of a solid phase supported oligonucleotide chain is exchanged for the amino portion of a 5'-phosphoramidite of an incoming monomer which has a protected 3'-amino group. The resulting internucleotide phosphoramidite linkage is then oxidized to form a stable protected phosphoramidate linkage. The method of the invention greatly improves product yields and reduces reagent usage over currently available methods for synthesizing the above class of compound.
