Title: Cellule d'echantillon utilisee en spectroscopie optique
Inventor: EPPES WILLIAM R
IPC: G01N33/49
Filed: 1999-05-12
Abstract: L'invention porte sur une cellule (100) d'échantillon destiné à être utilisée en spectroscopie et comprenant deux parties (48, 52) réglables pour mettre à l'utilisateur de varier la géométrie de la section transversale de la voie (16) d'écoulement de la cellule entre au moins deux configurations distinctes. Dans une première position, la voie d'écoulement présente une petite surface transversale de sorte que le parcours le long de cette voie soit court et que puisse y être généré un écoulement de fluide à haute vitesse. Ceci permet d'utiliser de petites quantités d'échantillons et facilite la mesure optique des échantillons tels que le sang présentant une turbidité. Dans une seconde position, la voie d'écoulement a une section transversale plus large pour permettre le passage des caillots et faciliter son nettoyage. Le réglage de cette voie d'écoulement s'effectue par le déplacement coulissant des parties de la cellule les unes par rapport aux autres. Selon une réalisation, des surfaces (49, 53) d'accouplement planes coulissent les unes par rapport aux autres. Et selon une autre réalisation, les surfaces d'accouplement (249, 253) sont superposées et espacées, la distance les séparant pouvant être modifiée.

Title: Method of determining the nucleotide sequence of oligonucleotides and dna molecules
Inventor: HAYES MARK A
IPC: C12Q1/6869
Filed: 1999-04-30
Abstract: The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA  polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetric detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

Abstract: A scalable hub (200) divided into a plurality of internal hubs (202, 204, 206 and 208). Each internal hub is connected to a subsequent internal hub in a loop topology. The connection point for each internal hub to the interhub loop is a port (218, 236, 246 or 256) which either bypasses that internal hub, isolating the disconnected internal hub, or connects that internal hub to the interhub loop, such that data flows between that internal hub and the interhub loop. In addition the preferred embodiment provides graceful degradation when an internal hub connected to the interhub loop fails.

Title: Method and apparatus for regulating flow of a pumpable substance
Inventor: TREMOULET OLIVIER L JR
IPC: B30B5/00
Filed: 1999-06-17
Abstract: An apparatus and method for pressure processing a pumpable substance. In one embodiment, the apparatus includes a pressure vessel having an inlet port to receive the pumpable substance and an outlet port to remove the pumpable substance.

Title: Liquid dispenser
Inventor: GENTRY SHAWN
IPC: B67D1/04
Filed: 2001-04-03
Abstract: A liquid dispenser is provided for dispensing a desired amount of liquid from a bottle, without leakage or dripping.      The bottle is mounted in a fixture attached to a wall. The bottle includes an inlet and an outlet, with one-way valves operatively sealed in the inlet and outlet ports.

Patent CA-2345981-A1 (CA)
Title: Mixing impeller system
Inventor: WEETMAN RONALD J
IPC: B01F27/91
Filed: 1999-09-22
Abstract: An axial flow mixing impeller system (10) for efficient mass transfer by control of size of the bubbles of the fluid which is being dispersed is obtained by creating passageways (5) through the impeller blades for flow between the suction (48) and pressure (46) sides of the blades which disrupts the flow over the suction sides of the blades thereby reducing the tendency for bubbles to grow into large bubbles which instead of being dispersed, rise to the surface without effective mass transfer to the liquid. The blades (24, 26, 28) may be slotted inwardly from the tips (52) to provide the passageways or may be formed from segments (114, 116, 118), gaps between which provide the flow passageways. The segments may be in edge-to-edge abutment. Gas-to-liquid dispersion may be improved by sparging below the impeller at the bottom of the tank and between the impellers in the tank, enabling gas supply as different pressures.

IPC: C08F220/56
Filed: 1999-09-06
Abstract: A composition which is photopolymerizable in the presence of water comprises:  (a) a first monomer having olefinic unsaturation and a flexible hydrophillic chain and which may be polyethylene glycol ethyl ether methacrylate or methoxypolyethylene glycol methacrylate;  (b) a second monomer having olefinic unsaturation, high free radical polymerization efficiency and which imparts tackiness on curing, and which may be N,N-dimethylacrylamide or 2-hydroxyethylacrylate; (c) a cross-linking agent; and (d) a photoinitiator. The composition may be formed into a thin layer containing 2-40 wt.% of water before it is cured so that the product is a film. The cured film is transparent, adheres selectively to dry skin, and can be used as a wound dressing. Where the second monomer provides conductivity-imparting groups it may also be used as an electrode (e.g. as a grounding plate). If desired, 2-20 wt.% of a low molecular weight polyol e.g. propylene glycol may be added to increase the adhesiveness of the cured film and/or a water-soluble natural or synthetic polymer may be added to increase its adhesiveness, tackiness and improve the casting process.

Title: Reducing waiting time jitter
Inventor: RUDE MICHAEL J
IPC: H04J3/07
Filed: 1999-11-02
Abstract: Circuits and methods are described which reduce waiting time jitter at a synchronizer/multiplexer by using a "sub-bit" comparison of a clock associated with an unsynchronized data stream and a clock associated with a synchronized data stream to generate a threshold level for use in determining when to stuff bits into the synchronized data stream. The term "sub-bit" means that the phase difference, as measured by, for example, the location of pointers associated with the two clocks, is precise to a fraction of a bit.
