Abstract: Dans une analyse dépendant des lipides permettant d'établir un diagnostic, on utilise une suspension aqueuse stable d'un phospholipide qui présente normalement une structure hexagonale (HII) lorsqu'il se trouve en dispersion dans un milieu aqueux sans détergent, ladite suspension renfermant le phospholipide, un détergent, et une phase aqueuse. Dans la suspension stable, le phospholipide reste en suspension dans des conditions de température égales à 25 C pendant au moins une heure. Ladite suspension est adaptée pour utiliser le phospholipide dans une analyse recherchant des anticoagulants lupiques, ladite analyse comprenant l'étape de pré-inscription d'un échantillon d'essai avec le phospholipide. Dans un autre aspect de l'invention, une analyse est utilisée pour déterminer si un patient possède un anticoagulant lupique, cette analyse s'effectuant comme suit: a) on recueille des premier et deuxième échantillons du plasma du patient; b) on fait incuber le premier échantillon avec la suspension de phospholipide stable et aqueuse de cette invention; c) on effectue une analyse dépendant des lipides permettant d'établir le diagnostic sur les premier et deuxième échantillons, cette analyse fournissant une indication positive lorsq'on l'utilise pour analyser un échantillon renfermant des anticoagulants lupiques; et d) on compare les résultats des analyses effectuées sur les premier et deuxième échantillons, la présence d'un résultat normal pour le premier échantillon et d'un résultat positif pour le deuxième échantillon indiquant que le patient possède un anticoagulant lupique.

Abstract: Reducing corrosion and lime deposits caused by water impurities on surfaces exposed to water is performed by the presence of magnetically treated water. It is found that the reduction of corrosion or encrustation is much more effective if water from a magnetically treatment unit (1) is passed over the affected surfaces to flush them as directly as practically possible and at as high a flow speed of practically possible. Water that has been used to flush these surfaces is recycled through the magnetic treatment apparatus (1) by means of a pump (8) and used to flush the affected surface again. Deflecting devices of the magnetically treated water are useful for flushing the affected surfaces effectively. A helical heat deflector inside a pipe can produce a spiral flow in a pipe for bringing as much of the treated water into contact with the walls of a pipe. A system of nozzles (10) is useful for directing flows of treated water along the walls of a tank. A spiral loop (12) with perforations facing a heating element or a cluster (11) of heating elements is useful for directing magnetically treated water at surfaces of heating elements. Magnetically treated water can similarly be used in cooling towers and air treating installations.

Abstract: The continuous generation of chlorine dioxide by reduction of sodium chlorate with sulphur dioxide, sodium chloride, methanol or some other suitable reluctant requires acid reaction conditions. According to the invention, the acidity is maintained, completely or partially, with acid produced by the electrolysis of a solution of sodium sulphate (Na2SO4 or Na3H[SO4]2). This sulphate is obtained by crystallization and redissolution of sodium sulphate formed in the chlorine dioxide generating process. The electrolysis of the sodium sulphate is limited for reasons of efficiency, such that only a part of the sulphate is decomposed to acid, whereas the remainder is recycled together with the acid to the reactor, where chlorine dioxide is generated. Sodium hydroxide, oxygen gas and hydrogen gas are also formed during the process of electrolysis and are utilized within the pulp manufacturing process.

Abstract: Des nanosols permettent de stabiliser des solutions à dispersion colloïdale de substances actives peu solubles dans l'eau avec de la gélatine ou ses dérivés, par régulation du point iso-ionique (PII, équivalent à une charge neutre) de la gélatine et des particules de la substance active superficiellement chargées de sorte qu'ils coïncident partiellement ou entièrement. Afin de neutraliser la charge du système constituée de particules de substance active et de gélatine, on compense la charge superficielle des particules en conférant une charge contraire correspondante aux molécules de gélatine. A cet effet, on ajuste une charge déterminée des molécules de gélatine en relation avec leur point isoélectrique (PIE) et la valeur de pH de la solution. En stabilisant ainsi l'état presque monodispersé généré, on réduit fortement la maturation d'Ostwald des particules colloïdales de la substance active peu soluble. On peut ainsi obtenir une forme utilisable en pharmacie présentant des propriétés nouvelles, contenant des composés inorganiques et organiques de manière générale peu solubles dans l'eau, notamment des substances médicamenteuses à biodisponibilité problématique. Parmi les médicaments préférés on compte le glibenclamide et les dérivés d'acide 3-indolylacétique, par exemple l'indométacine ou acémétacine. L'invention concerne également des procédés de préparation de ces nanosols.
Patent CA-2125791-C (CA)

Abstract: The present invention features a method and an apparatus for preventing lift chains from becoming slack in a lift truck with a "man-up" feature installed.  Lift trucks are generally those vehicles that feature hydraulically controlled lift masts with a chain supported fork carriage.          Operators of these lift vehicles with the remote lift and lower feature are generally lifted and lowered by these masts, known in the trade as a "man-up" condition.  It is quite desirable to prevent a slack chain condition in the man-up mast position.  The invention features a pressure transducer for monitoring a drop in hydraulic fluid pressure established by the flow control valve that regulates the lowering speed of the mast during the remote mode, i.e., when the fork carriage is being lowered by the operator in the platform attached to the fork carriage.  The invention turns off the normally closed load-holding valve when the hydraulic pressure drops below a predetermined value, which stops the flow of hydraulic fluid back into the reservoir.          This, in turn, stops the cylinder(s) from lowering and keeps the fork carriage lift chains from becoming slack.

Title: Voice actuated switching system
Inventor: BOWEN DONALD JOHN
IPC: H04R3/00
Filed: 1995-03-28
Granted: 1998-10-13
Abstract: A voice-actuated switching system connects one or more microphones to an audio line in accordance with the output signal levels from each of the microphones. To reduce the effects of degradation of speech signals due to reverberation and noise pickup, the switching system uses directional microphones housed in a circular enclosure and arranged in a conference array configuration with response patterns aimed outwardly from the center of the enclosure. The switching system also uses a voting algorithm to select for activation the appropriate microphones indicative of the position of one or more people speaking and a variable weighting factor for gradually turning on or off the signal from each activated microphone that is coupled to the audio line. Typically one microphone will be selected to monitor a person speaking. Since its response pattern is normally pointed in the direction of the person speaking, it is less sensitive to speaker echo due to reverberation. If two people are simultaneously speaking on opposite sides of the array of directional microphones, however, two generally opposed microphones areselected, and the amount of reverberation increases only slightly over the amount of reverberation  that would be present if just a single microphone were employed.
