Inventor: FRANK DAVID
IPC: H01M8/24
Filed: 2000-08-04
Abstract: In a fuel cell, at least one humidification cell stack is provided as an extension of the fuel cell. The cells of the humidification cell stack can be structurally similar to and include the same membrane as the individual cells of the fuel cell stack.  Flows of fuel and oxygen are then arranged to pass through the humidification cell stack for exchange of moisture. Preferably, there are humidification sections at either end of the fuel cell stack, to enable moisture exchange between incoming fuel and discharged oxygen to one end and incoming oxygen and discharged fuel at the other end. The arrangement is expected to enhance uniform operating conditions within the fuel cell stack itself, so as to ensure optimum operating conditions throughout the fuel cell stack.

Title: Capteur optique et procede de fonctionnement
Inventor: SULLIVAN KEVIN J
IPC: G01N21/78
Filed: 1999-01-18
Abstract: Cette invention concerne un capteur optique à usage unique multiple comprenant une série de bandes de détection continues qui sont disposées sur un réseau servant de substrat. Au moins une chambre pour échantillon est disposée en travers d'une partie discrète de la série de bandes de détection, ceci de manière à faciliter l'analyse d'un échantillon qui y est déposé. La chambre pour échantillon est capable de se déplacer ou, dans une autre variante, des chambres d'échantillon supplémentaires peuvent être utilisées afin de mesurer par la suite des échantillons additionnels en des parties discrètes non utilisées des bandes de détection. La continuité des bandes de détection permet d'obtenir un certaine consistance sur toute leur longueur, ce qui permet d'utiliser les données d'étalonnage obtenues d'une partie discrète des bandes de détection afin de tester un échantillon nouveau en une autre partie discrète desdites bandes. Ce système permet avantageusement d'éviter que toute partie discrète particulière des bandes de détection n'entre en contact avec plus d'un échantillon, ce qui a pour effet d'améliorer les performances du capteur.

Title: Feed-forward amplifier and controller of the same
Inventor: SAKAMOTO HIRONORI
IPC: H03F1/32
Filed: 2000-12-04
Abstract: A feed-forward amplifier and a controller thereof. Two types of second pilot signals, sum frequency and difference frequency of a base pilot signal and a local oscillation signal, are generated by an injection-side mixer and injected into a distortion detection loop. Part of a signal appearing at an output terminal is branched, converted in frequency by a detection-side mixer using the local oscillation signal, filtered by a narrow-band filter, input to a synchronizing detector with the filtered output of the filter as error signals, and synchronizing detected with reference to the base pilot signal so as to generate control signals for a distortion rejection loop. The spectrums of the second pilot signals may be spread. A process to cancel the input signal component at the detection side may be performed. A simple circuit configuration enhances the distortion component rejection and suppression effect and shortens the time required until an optimum control state is established.
Patent CA-2327591-A1 (CA)
Title: Desulfurization of exhaust gases using activated carbon catalyst
Inventor: SONEHARA NAONORI
IPC: B01J31/06
Filed: 1999-04-06
Abstract: Intended is to improve the activity and stability of an activated carbon catalyst for use in recovering and removing sulfur oxides contained in exhaust gases as sulfuric acid using a catalytic oxidation. An activated carbon is mixed with a fluororesin and the resultant mixture is kneaded with application of a shearing force, and is molded into a given shape such as a granule, a plate or a cylinder, to thereby impart water repellency to the surface of the wall of a gap formed between activated carbon particles. When exhaust gases are flowed through a tower packed with this catalyst, it is preferred that the gases are flowed downwards, and that use is made of an activated carbon catalyst formed into a honeycomb shape which is composed of planes parallel to the direction of a gas flow mentioned above. Introduction of dilute sulfuric acid or water from the top of the tower to wash the surface of the activated carbon catalyst is effective for maintaining high activity and allows a catalyst layer to avoid closing or being contaminated even when exhaust gases contain dust.
Patent CA-2329515-A1 (CA)
Title: Silica-guanidiniumthiocyanate dna isolation using casein
Inventor: GOUDSMIT JAAP
IPC: C12N15/10
Filed: 1999-05-26
Abstract: DNA purified by the guanidiniumthiocyanate-silica procedure (Boom et al, J.  Clin. Microbiol. 28:495-503, 1990) from some sources (e.g. cerebrospinal fluid and urine) has appeared to contain inhibitors of DNA processing enzymes (Taq DNA polymerase, restriction enzymes and DNA ligase). These inhibitors were, at least in part, introduced by the purification procedure itself. The inhibition of DNA processing enzymes could be relieved by the inclusion of alpha casein into the guanidiniumthiocyanate (GuSCN) containing lysisbuffer. Alpha casein is copurified with DNA by simultaneous binding to the silica particles and is subsequently eluted together with the DNA in the last step of the purification procedure after which it exerts its beneficial effects for DNA processing enzymes.
