Patent CA-2337099-A1 (CA)
Title: Enzymes for biopolymer production
Inventor: MADISON LARA
IPC: C07K19/00
Filed: 1999-07-30
Abstract: In order to optimize the flux or flow of carbon intermediates from normal cellular metabolism into PHAs it is desirable to optimize the expression of the enzymes of the PHA biosynthetic pathway. Gene fusions are genetic constructs where two open reading frames have been fused into one and encode hybrid proteins and in some cases bifunctional hybrid enzymes. Linkers may be added to spatially separate the two domains of the hybrid protein. In the case of enzymes which catalyse successive reactions in a pathway, the fusion of two genes results in bringing two enzymatic activities into close proximity to each other. When the product of the first reaction is a substrate for the second one, this new configuration of active sites may result in a faster transfer of the product of the first reaction to the second active site with a potential for increasing the flux through the pathway.

A machine operator utilizes the data to optimize the operation of the band saw (10) as it proceeds through a series of cutting operations.
Patent CA-2341140-A1 (CA)
Title: Method for activating solid polymer electrolyte fuel cells
Inventor: KNIGHTS SHANNA
IPC: H01M8/10
Filed: 2001-03-19
Abstract: Solid polymer electrolyte fuel cells are typically assembled in a dry state and need to be activated before normal power producing operation can begin. In the activation process, the solid polymer electrolyte and catalyst layers are :hydrated. Activation is often accomplished by operating the fuel cell under controlled conditions as part of the assembly process, thereby generating water for hydration in-situ. However, the fuel cell can essentially be activated prior to its operation in a rapid, simpler manner by directing water vapor, in particular steam, over the fuel and/or oxidant electrodes.

Title: Oscillating assembly for pivoting a blanking die
Inventor: GENSEBERGER ERICH
IPC: B23D15/00
Filed: 1999-10-26
Abstract: The present invention relates to an oscillating assembly for pivoting a blanking die that is constructed and arranged to cut blanks from sheet material. The oscillating assembly comprises a die supporting structure that pivots about a pivot axis. The die supporting structure receives and supports the die such that the sheet material can be fed into the die in a feeding direction and such that the pivoting of the die supporting structure pivots the die relative to the sheet material.      A reversible rotary driving assembly rotates a rotatable output shaft in opposing first an second rotational directions.      A linearly movable die driver is operatively connected to the output shaft such that (a) rotating the shaft in the first rotational direction thereof moves the die driver generally linearly in a first die driving direction and (b) rotating the shaft in the second rotational direction thereof moves the die driver generally linearly in a second die driving direction opposite the first die driving direction. The die driver is operatively connected to the die supporting structure such that (a) moving the die driver in the first die driving direction thereof as aforesaid pivots the die supporting structure to a first cutting position wherein the blanking die can cut a first blank from the sheet material fed therein and (b) after cutting the first blank and advancing the sheet material relative to the die in the feeding direction, moving the die driver in the second die driving direction thereof as aforesaid pivots the die supporting structure to a second cutting position wherein the blanking die can cut a second blank from the sheet material.

Title: Fuel cell assembly unit for promoting fluid service and design flexibility
Inventor: CARLSTROM CHARLES M JR
IPC: H01M8/24
Filed: 1999-10-06
Abstract: A first flow field plate (200) of a fuel cell assembly (100) includes a first flow channel (204) thereon. Fluid is conducted to the flow channel through an opening (858) extending through the first plate. An adjacent second plate (510) cooperates in providing a surface (508) for a flow path (501) between a manifold (854) and the opening (858). Additional surface(s) (506, 512) may cooperate in providing the flow path (501) and/or structural support therefor.  A formation (862) on the first plate (200) impedes fluid communication from the manifold (854) on a plate face (202) including the first flow channel (204). The formation may provide structural support in a (e.g., PEM-type) fuel cell assembly (100), and/or a clamping and/or gasketing function for a membrane electrode assembly (310). A second flow path may similarly be provided for humidification of the (e.g., reactant) fluid. The second flow path may include flow regulator(s) and/or metering orifice(s) (860). The second plate (510) may include a second flow channel thereon (1204). Flow path(s) for the second plate may be configured to provide the aforementioned surface (508) or the flow path for the first plate without interference among fluid service for each plate. A multiplication of manifolds for a fluid may allow a manifold to omit service for a plate, where a different manifold provides the omitted service.

Title: Blood processing systems and methods with sensors to detect contamination
Inventor: MULLER MATTHEW R
IPC: G01N33/483
Filed: 2000-08-29
Abstract: Blood processing systems and methods employ two sensors (334, 336), one (334) to detect a condition of plasma exiting a separation device (18) and another sensor (336) to detect a condition of a cellular component exiting the separation device (18). The first sensor (334) detects, e.g., contamination of the plasma due to the presence of unwanted cellular components. The second sensor (336) detects, e.g., dilution of the cellular component due to presence of plasma. Blood processing parameters are carried out based, at least in part, by conditions detected by one or both of the sensors (334, 336).

Patent CA-2362440-A1 (CA)
Inventor: DIXON RICHARD A
IPC: C12N15/53
Filed: 2000-03-08
Abstract: L'invention concerne les gènes CYP93C du soja et de Medicago truncatula isolés, ces gènes codant pour un cytochrome P-450 capable de catalyser la migration aryle d'une flavanone pour produire un produit intermédiaire d'isoflavanone ou une isoflavone. Il est maintenant possible de modifier génétiquement des végétaux pour produire des isoflavones susceptibles d'être bénéfiques pour l'homme et d'améliorer la résistance aux maladies chez les végétaux. On peut donc produire des isoflavones dans des espèces végétales transgéniques ne contenant pas naturellement d'isoflavones, autrement dans des espèces autres que les légumineuses. Dans une variante, on peut provoquer une biosynthèse d'isoflavonoïdes, induite par une infection, dans des espèces non légumineuses, ce qui vient compléter avec avantage la défense de la phytoalexine contre les agents pathogènes microbiens, une surexpression de la voie des isoflavonoïdes dans les légumineuses permettant par ailleurs une amélioration qualitative de cette réaction de défense. Enfin, on peut transformer positivement l'efficacité de nodulation, et donc le rendement végétal, en modifiant l'importance de la production d'isoflavonoïdes dans les racines des légumineuses.

Title: Method and apparatus for producing a data stream of code words of variable lengths and method and apparatus for reading a data stream of code words of variable lengths
Inventor: SCHUG MICHAEL
IPC: H03M7/40
Filed: 2000-01-17
Abstract: In a method for producing a data stream of code words of variable lengths which are divided up into a plurality of sets of code words, wherein a raster having segments is specified for the data stream, wherein two adjacent raster points define a segment, code words of the first sets are written into the data stream starting at raster points.      Subsequently, code words of the second set are written into the data stream pursuant to a predetermined assignment rule, wherein each code word of the second set is assigned to a different segment. Entire code words or parts of code words which cannot be written according to their assignment, are stored and entered into the data stream in further attempts, wherein the assignment by a predetermined regulation is changed from attempt to attempt. This procedure is analogously repeated for any further set which may be present. Thus, the ends of code words of the second set are decoupled from the starts of following code words of the second set, since the corresponding code words of a set are written segment by segment, which results in a reduction of error propagation.
