Title: Stable recombinant yeasts for fermenting xylose to ethanol
Inventor: HO NANCY W Y
IPC: C12N15/90
Filed: 1997-05-06
Abstract: Described are recombinant yeast which ferment xylose to ethanol and which maintain their ability to do so when cultured for numerous generations in nonselective media. The preferred yeast contain multiple copies of integrated genes encoding xylose reductase, xylitol dehydrogenase, and xylulokinase fused to promoters which are non-glucose inhibited and which do not require xylose for induction. Also described are preferred methods for integrating multiple copies of exogenous DNA into host cells by transforming cells with replicative/integrative vectors, and then replicating the cells a number of times under selective pressure to promote retention of the vector in subsequent generations. The replicated vectors thus serve to integrate multiple copies of the exogenous DNA into the host cells throughout the replication/selection phase. Thereafter the selective pressure can be removed to promote loss of the vector in subsequent generations, leaving stable integrants of the exogenous DNA.

Patent CA-2265908-A1 (CA)
Inventor: NELSON MARK
IPC: A61M5/28
Filed: 1997-10-23
Abstract: L'invention concerne un procédé et un appareil associés à une rétraction sûre d'aiguilles médicales (140, 140', 540, 1140, 2070, 2320) après usage. Des modes de réalisation de systèmes d'aiguilles autorétractables sont décrits, qui sont destinés à la fois à des prélèvements de sang (10, 610, 820, 2010, 2400), à des systèmes d'insertion de seringue (510, 900, 1010) et de cathéter (400, 800, 2300). La fabrication de cet appareil requiert seulement un nombre minimal et une complexité minimale d'éléments, de sorte que qu'un coût projeté de fabrication est potentiellement assez faible pour permettre à l'appareil d'être compétitif sur le plan du coût, par rapport à des systèmes d'aiguilles non autorétractables existants. Des procédés de fabrication et d'assemblage de chaque mode de réalisation sont également décrits. Dans un mode de réalisation pour prélèvement de sang (2400), ledit appareil peut être fabriqué avec seulement trois éléments moulés. Des mécanismes d'aiguille rétractable, accumulateurs d'énergie, comprennent un tubage élastique (180, 570, 1180) et des éléments de piston (416, 2351) produisant du vide. Dans un mode de réalisation de tubage élastique (10, 510, 610, 800, 820, 900, 1010, 2010, 2400), une régulation sélective, constrictive des volumes de tubage (180, 570, 1180) en extension permet d'inhiber de façon efficace un flux de régurgitation provenant de l'aiguille (140, 140', 540, 1140, 2070, 2320). Dans tous les modes de réalisation (10, 400, 510, 610, 800, 820, 900, 1010, 2010, 2300, 2400), la rétraction de l'aiguille constitue une opération réalisable avec une seule main, permettant au technicien d'utiliser son autre main pour traiter la plaie. Une combinaison d'éléments comprenant le logement (20, 30, 80', 500, 520, 620, 630, 752, 802, 842, 902, 904, 1020, 2020, 2200, 2302, 2402) de l'appareil et un capuchon d'aiguille (120, 120', 268, 524, 720, 720', 804, 1190, 2350), est utilisée comme conteneur de transport, lequel permet d'éviter une contamination accidentelle par une aiguille médicale (140, 140', 540, 1140, 2070, 2320) sans avoir recours à un emballage spécial, ce qui réduit encore les coûts de fabrication de l'appareil.

Finally, it is determined which parts of the original images can be reproduced based on information recalled from the memory and if there is confusion or interchange with other images.
Patent CA-2273607-A1 (CA)
Inventor: TUCKER JAMES C
IPC: E21B17/06
Filed: 1999-06-01
Abstract: A coiled tubing drilling hydraulic disconnect for use in disconnecting a tool from a length of tubing or other tool string. The apparatus has an upper housing and a lower housing with a splined ring threadingly engaged with the lower housing.      A spline in the splined ring engages a spline on the upper housing so that torque may be transmitted therebetween. Lugs are disposed through windows in the lower housing below the splines, and a bushing is disposed between the splined ring and the lugs. Relative rotation between the upper and lower housings causes the splined ring to tighten against the bushing and lugs, thereby eliminating play therebetween. A lug prop disposed in the upper housing may be hydraulically actuated so that the lugs may move to a disconnect position, thereby releasing the upper housing from the lower housing. Because the windows are disposed below the splines, no torque or bending are applied to the windows, and the windows and lugs are shaped to minimize stress concentrations.

Patent CA-2280218-A1 (CA)
Title: Weatherproof outlet cover
Inventor: HAYDUKE NICHOLAS P
IPC: G06F9/45
Filed: 1999-08-10
Abstract: A weatherproof outlet cover for protecting an outdoors electrical outlet is disclosed. The cover includes a housing which is hinged at one corner so that the cover can be used for either a horizontally or vertically oriented electrical receptacle. With the corner hinge, the cover closes due to gravity in either position, thus ensuring that the cover will always remain closed unless it is purposely held open. The hinge preferably includes a baffle which directs water down and away from the mating surfaces of the housing and back body. The back body may have a recessed and key shaped opening so that existing screws in a receptacle need only be backed partially out, rather than being completely removed. A wall plate may be snapped into place within the back body using a unique tab and tooth rack combination. To keep the housing closed relative to the back body, a snap may be actuated in the closed position, and a pair of aligned lock holes allows for a combination or key lock to prevent unauthorized access to the hidden receptacle. Cords of plugs inserted into the outlets may exit through an opening at a corner opposite the corner where the hinge is located. Thus, the exit opening faces in a generally downward direction whether the cover is placed horizontally or vertically. A pair of rubber flaps prevents rain water from back-splashing into the enclosure.
