Abstract: Cette invention a trait à une technique de contrôle de la présence d'une séquence nucléotidique cible dans un prélèvement. Cette technique consiste, (a), à ajouter au prélèvement, suspecté de contenir cette séquence nucléotidique cible, une sonde fluorescente marquée spécifique de la séquence, un agent de fixation d'ADN double hélice, capable d'absorber l'énergie fluorescente émanant de la sonde, mais n'émettant pas de lumière visible, (b), à soumettre le mélange ainsi constitué aux effets d'une réaction d'amplification dans laquelle la séquence cible est amplifiée, (c), à soumettre ce prélèvement à des conditions dans lesquelles la sonde s'hybride à la séquence cible et, (d), à contrôler la fluorescence émanant du prélèvement. Il est possible, notamment, d'utiliser cette technique pour contrôler des réactions d'amplification comme la PCR, de sorte qu'il est possible de déterminer l'importance de la séquence cible présente dans le prélèvement. Il est possible, en sus ou en alternance, d'utiliser cette technique pour produire des données de déstabilisation duplex, notamment une information d'hystérésis de fusion aux fins du contrôle de l'amplification ou pour la détection et la quantification de polymorphismes ou de variation allélique, ce qui la rend des plus utile, s'agissant de diagnostic génétique.

Filed: 2003-11-14
Abstract: A method for removing metal contaminants from acidic mine wastewater using lignin derivatives, such as lignosulfonates and kraft lignin, an alkali coagulant, such as a lime compound, and an alkaline composition for increasi ng the pH. The lignin derivatives are dispersed in the wastewater and the coagulant is added, increasing the pH to about 4.5 - 8.5 and causing the formation of a floc. The alkaline composition is then added to bring the pH to about 9 to 10, causing the further formation of a floc. Optionally, air oxidation is carried out, reducing the pH to about 8.1 - 8.6. Optionally, a ferric or ferrous salt may also be added. The flocs comprise metal-lignin colloids, metal hydroxides and metal salts. The flocs coagulate to form a sludge. Optionally, fly ash or diatomaceous earth may be added to increase t he density and stability of the sludge. The sludge that is formed contains the metals and is separated from the treated water by filtration.

Patent CA-2509534-A1 (CA)
Inventor: PETROVIC JOHN E
IPC: B05B1/18
Filed: 2000-04-07
Abstract: The showerhead engine assemblies provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns.  The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns. Spinner rotation starts or stops depending upon the position of the spinner relative to the stator, since the stator includes a pair of stop flanges that engage and disengage with the spinner. When the spinner is disengaged and free to rotate, water flow through passages in the spinner cause spinner rotation, creating a vortex and pulsating spray patterns. The series of showerhead engine assemblies include component parts that are interchangeable, the number of component parts being minimal, the interchangeability reducing the number of spare parts necessary to repair the series of showerhead engine assemblies.

Title: Property correcting system of automatic transmission
Inventor: MIYAKE YASUYUKI
IPC: F16H61/02
Filed: 2004-03-17
Abstract: In a property correcting system of an automatic transmission according to the present invention, a difference of revolutions between input revolutions Nin of a torque converter and turbine revolutions Nt is compared with target rotational difference .DELTA.N, and is increased/reduced by the feedback operation (S6 and S7). It is checked to see if the difference of revolutions is converged to the target rotational difference .DELTA.N (S8). When a driving duty duty which is converged to the target rotational difference .DELTA.N is within a shipping determining standard, the value is stored (S10). A differential value between the stored driving duties duty of the respective automatic transmissions and the reference value is written to a TCU, as the amount of correction of the respective automatic transmissions, thereby correcting the variation in properties of the individual automatic transmissions, starting from the initial shipping timing. A preferable shift quality is obtained without prompting the learning based on the actual driving.
