Patent CA-2473553-C (CA)
Title: Fuel cell oxygen removal and pre-conditioning system
Inventor: MITCHELL PHILIP JOHN
IPC: B60R9/04
Filed: 2003-01-15
Granted: 2011-03-15
Abstract: A fuel cell having an anode, a cathode and an ion exchange membrane is supplied by hydrogen fuel through an anode fuel delivery conduit. A  recirculation loop is provided to recycle gases in the fuel delivery conduit to a mixing point where a controlled flow rate of fuel is supplied and mixed therewith. Any oxidant species remaining in the fuel delivery conduit are thereby combusted in a controlled manner to avoid damage to the fuel cell membrane-electrode assembly. Small quantities of oxidant may be deliberately introduced into the fuel delivery conduit to generate water vapour and heat to pre-condition the fuel delivered to the anode. Such preconditioning assists in hydration control of the membrane, and temperature control of the membrane-electrode assembly for optimum fuel cell performance.

Title: Fall protection restraint apparatus
Inventor: FRANKE GARY J
IPC: A62B35/00
Filed: 2002-10-09
Granted: 2010-08-31
Abstract: A fall protection restraint apparatus that is utilized during building construction comprising a base (20) that rests on the lowest floor surface of a building during construction. A number of poles (36) are connected to the base sequentially, as construction height requires, to form a structurally sound column. Support cables (40) are connected between the poles and the building under construction to horizontally support the column by forming a guyed matrix. A retractable lifeline lanyard (48) is attached to D-rings on the end cap (54) on the uppermost pole (36b), thereby allowing the lanyard to expand and retract freely until a sudden tug impedes and secures the lanyard's movement. A construction worker (50) wears a fall arrest harness (52) that is connected to the lanyard, thus providing protection. In the event of a fall, the lanyard limits and maintains the minimal distance between the worker and the column, thereby precluding a fall to the surface below.

Title: Routing system and method for synchronizing
Inventor: WARD DAVID DELANO
IPC: G06F11/14
Filed: 2003-11-12
Granted: 2008-07-22
Abstract: A routing system provides for transparent routing system failover by checkpointing route prefixes during normal operation by maintaining a route prefix table. After failure of a primary routing processor, routing with peer routing systems is synchronized through the use of this prefix table. The prefix table is managed by the primary routing processor and is accessible by a backup routing processor at least after failure of the primary routing processor. Upon the detection of a failure, a backup routing processor solicits routes from peer routing systems in response to the failure and generates a backup routing database from the routes received from peer routing systems. The backup routing processor also compares prefixes of routes in the backup routing database with prefixes in the prefix table, and sends route withdraw messages to the peer routing systems for routes having prefixes listed in the prefix table and not identified in the backup routing database.

Title: A milk conveyer device
Inventor: JOHANNESSON LEIJ BOERJE
IPC: A01J7/02
Filed: 2003-12-19
Granted: 2011-11-22
Abstract: The invention relates to a milk conveyer device (100) for an animal. The milk conveyer device is to be implemented in a milking arrangement which comprises a milk storage reservoir (101) coupled to a milking attachment for attaching to an animal to be milked through a main milk conduit (103, 105). A sample element (109, 111) extracts milk, which is collected in a sample reservoir (115, 117) is connected to an analysis element (129) through an analysis conduit (123, 125). During the flow of the milk from the sample reservoir to the analysis element (129), the milk itself provides a cleaning effect. The flow is initially at a high flow rate and later at a reduced flow rate. A plurality of analysis conduits (123, 125) are connected to the analysis element (129), which comprises a selector unit (127), which couples milk from one of the analysis conduits (123, 125) to the analysis element (129). The device provides a self-cleaning effect and a low carry-over of milk between the two successive milking operations, i.e. between the milk of two different animals.

Filed: 2004-04-17
Granted: 2013-01-29
Abstract: L'invention concerne un dispositif de déclenchement/d'allumage dans un générateur de Marx comportant n condensateurs à cascade - n étant un entier naturel supérieur à 1 et autant de commutateurs/éclateurs, ainsi que 2(n-1) voies de charge, les éclateurs fonctionnant en auto-décharge. Ce dispositif de déclenchement/d'allumage est doté d'au moins un transmetteur d'impulsions relié à un générateur d'impulsions. Dans au moins une des voies de charge du générateur de Marx, une surtension est générée de manière chronologique et à court terme sur l'éclateur adjacent, cette surtension étant suffisante pour une auto-décharge. La voie de charge court-circuite l'éclateur au moyen du condensateur à cascade associé, mis à part le côté sortie. L'enroulement de sortie du transmetteur d'impulsion agit pendant la charge comme bobine de charge/inductance de charge, l'enroulement d'entrée étant relié au générateur d'impulsions. L'impulsion de tension générée par le transmetteur d'impulsions lors de l'allumage/du déclenchement du générateur d'impulsions s'ajoute à la tension de charge du condensateur à cascade associé et produit ainsi à court terme la surtension nécessaire à l'auto-décharge de l'éclateur adjacent.

Title: Corrosion reduction with amine scavengers
Inventor: STARK JOSEPH L
IPC: C07C7/148
Filed: 2004-05-19
Granted: 2010-08-03
Abstract: Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides.  The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCI) to form corrosive amine salts.
