Abstract: A method and system for displacing water from a porous geological formation are provided. The zone to be displaced is defined by the injection of water into one or more barrier wells around the zone. One or more gas injection wells and water production wells are located within the zone.  During pressurized gas injection within the zone, the barrier wells are operated to achieve a hydraulic pressure barrier surrounding the zone that is sufficient to prevent penetration therethrough by the injected gas.  The well system is operated to concurrently limit gas entry into the water production well. Accordingly, the gas displaces water downward within the zone such that water is produced at the water production wells.

Abstract: The invention relates to the field of vacuum cleaning and in particular the collection of air-entrained debris, for example in a filter bag. The invention is a filter for use in vacuum cleaning apparatus, which comprises fine planar filtration means and coarse planar filtration means both being adapted to be placed in a suction- induced air stream with the coarse filtration means disposed upstream of the fine filtration means, wherein the fine filtration means serves to provide a fine filter for retaining dust particles and wherein the coarse filtration means comprises a relatively coarse filter material having a thickness of at least 4mm which provides a matrix volume in which dust may be collected. The fine planar filtration means may be a filter web arranged in the form of a collection bag. The volume occupied by the coarse filtration means comprises at least 2 %, preferably at least 5 %, most preferably at least 10 % of the maximum internal volume defined by the collection bag. The filter provides significantly enhanced fine dust collection capability, particularly for the grinding of brick or plasterwork where large amounts of fine ceramic dust are continuously generated and which tends to foul and degrade conventional filters.

Abstract: Aspects of the present invention provide a lens comprising a non- rotationally symmetric aspheric optical element, surface or feature and a rotationally symmetric aspheric optical element, surface or feature. The non- rotationally symmetric aspheric optical feature can be a progressive power region. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can be in optical communication when located on different surfaces of a lens or can be collapsed to occupy a single surface of a lens. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can each contribute to the add power of a lens. Distortion (e.g., astigmatism) of a lens of the present invention can be reduced (e.g., globally and/or locally) by optically combing the non-rotationally symmetric aspheric optical feature with the rotationally symmetric aspheric optical feature. Accordingly, the effective or useable vision zones of a lens of the present invention can be increased.

A plural-ity of samples is analyzed and a plurality of measured variables is obtained from a spectrometer. A processor executes a number of steps. The plurality of measured variables is divided into a plurality of measured variable subsets. Principal component analysis followed by variable grouping (PCVG) is performed on each measured variable subset, producing one or more group representa-tions for each measured variable subset and a plurality of group representations for the plurality of measured variable subsets.  While the total number of the plurality of group representations is greater than a maximum number, the plurality of group repre-sentations is divided into a plurality of representative subsets and PCVG is performed on each subset. PCVG is performed on the remaining the plurality of group representations, producing a plurality of groups of correlated representations of variables.

Il peut évoluer sur terre, dans la boue, dans les marécages, sur la neige, sur la mer dans les fonds marins ou en suspension dans l'eau. Éventuellement la puissance des moteurs/cylindres jumelée avec la coque de condensation pourra permettre au véhicule de prendre un envol. Son étanchéité lui permet également d'évoluer sans difficulté dans des environnements inhospitaliers tels que poussières, fumée, humidité extrêmes, absence d'atmosphère ou autres. Le véhicule est supporté et dirigé par des moteurs/cylindres étanches, de forme oblongue avec bossèlement apparenté à une vis sans fin. Chacun des moteurs/cylindres est totalement autonome en terme d'unité de force, d'accumulation d'énergie, de télé-contrôle et de radiobalisage (en instance de brevet). Le véhicule peut servir au transport de marchandises et de personnes ambulantes ou handicapées. A partir de pièces détachées, le véhicule peut être assemblé en moins de 5 minutes sans utilisation d'outil. Tous les accessoires qui peuvent y être rattachés s'installent également rapidement sans outils. Le véhicule est commandé par le biais d'un système électronique avec ou sans fil et permettant d'induire au véhicule tout type de déplacements avec ou sans mouvement de lacet. Un ordinateur de bord permet de programmer des contrôles de sécurité, des radiorepérages, des arrêts ou mouvements préenregistrés, etc. Le véhicule comporte l'ensemble des composantes nécessaire à un fonctionnement autonome et sécuritaire. Il peut ainsi, sans s'y limiter, évoluer de façon autonome entre les obstacles ; les éviter, décider du chemin alternatif, aviser le conducteur/utilisateur de la présence d'un obstacle

Abstract: A process for recovering solvent from spent oil sands solids is provided, comprising drying the solids using superheated steam to vaporize solvent and water;  compressing and condensing the vapors in a first heat exchanger (hot side) to produce condensates, comprising primarily condensed hot water, end uncondensed vapors; separating condensed hot water and solvent from the uncondensed vapors in a first separator; flowing the hot water through the first heat exchanger (cold side) to produce near-saturated steam; and superheating the near-saturated steam in a second heat exchanger to produce the superheated steam for drying the solids.  Uncondensed vapors from the first separator can be further condensed in a third heat exchanger to produce warm water, recovered solvent and uncondensed off gas, which can be separated in a second separator. Some of the warm water is combined with the hot water to produce the near-saturated steam for superheating. The off gas is oil scrubbed or combusted prior to release to the atmosphere.
