Title: An electric motor having an improved airflow cooling system
Inventor: COX KARMEN D
IPC: H02K9/06
Filed: 1998-04-02
Abstract: An improved design for a switched reluctance motor is disclosed that keeps the motor cool during operation and thereby improves the performance and reliability of the motor. The improved design employs three centrifugal fans mounted to the motor shaft, which are used to create two independent airflow paths, one of which cools the electronic components of the motor. The improved design also divides the functions performed by a single printed circuit board into two circuit boards, an upper circuit board and a lower circuit board. Another feature of the improved design includes locating the position/speed sensing encoder immediately below one of the centrifugal cooling fans. The disclosed construction provides for increased dissipation of heat that is generated by the motor and its electronic components. In this configuration, the printed circuit boards and other electronic components are located in such a manner that air can be circulated in a path to remove heat from these components.
Patent CA-2234286-A1 (CA)
Inventor: WARDLE DAVID G
IPC: F17C13/00
Filed: 1998-04-07
Abstract: An apparatus is provided for storing a multi-component cryogenic mixture as a liquid. The multi-component cryogenic mixture of interest contains at least first and second components. The first component is more volatile than the second component and the second component has a bubble point temperature atmosphere pressure, lower than that of the first component at an above atmosphere pressure. A container isprovided in the apparatus for storing the cryogenic mixture. An inevitable heat leakage causes a cryogenic mixture to vaporize so that the vapor phase of the mixture isenriched in the first component and the liquid phase in the mixture is enriched in the second component. A conduit communicates between locations of the container situated above and below the head space region of the container so that vapor phase stream flows into the reservoir, opened to the atmosphere is provided in communication with the container such that a liquid phase stream, made up of the liquid phase flows into the reservoir and develops an ever increasing second component concentration. As such, the liquid phase of the mixture is able to condense the vapor phase of the mixture within the conduit. The resulting liquid will fall back into the container under influence of gravity to stabilize the concentration of the first and second components within the container.

Title: Breathable nonwoven liquid barrier fabric and method
Inventor: ZUCKER JERRY
IPC: D04H1/58
Filed: 1998-04-30
Abstract: A porous, nonwoven fabric made from bonded fibers and/or filaments is provided, and a continuous film or layer of a liquid radiation curable resin is applied to the fabric surface. The liquid film is subjected to radiation to cure the liquid into a solid film bonded to the surface of the fabric. The film renders the fabric impervious to liquids but allows passage of liquid vapor, and the technique provides an alternative to more expensive ways to achieve the same barrier properties.

IPC: B24B9/04
Filed: 1999-02-01
Abstract: A device is disclosed which facilitates vertical aligning between an ice skate clamping jig (20) and a grinding disc (35) or roller (39). The grinding tool is spaced above a planar top (31 a) of a table (31 ) of the sharpening device.  It may be a single grinding tool such as a grinding disc (35) rotated about a vertical axis, or there can provided one disc (35) as described and a grinding roller (39) rotated about a horizontal axis on the same table (31) of the skate sharpening machine.

IPC: A61N5/06
Filed: 1997-08-29
Abstract: Wrinkles are comestically removed from a superficial area of mammalian skin tissue having an epidermal layer, a basal layer, and a dermal layer, by irradiating the dermal layer through the basal layer by means of visible or infrared radiation (such as a laser), the irradiation being selected to be absorbed by a chromophore in the dermal layer such that collagen present in the dermal layer is heated, while the basal layer remains intact so as to substantially inhibit contact of the dermal layer with ambient air.
Patent CA-2268398-A1 (CA)
Title: Liquid distribution system
Inventor: KNOEDLER CHRISTINA MARIE
IPC: B01L3/00
Filed: 1997-10-10
Abstract: The liquid distribution system of the invention will be formed of at least three plates, a feedthrough plate (300), a distribution substrate (310) and a reaction cell plate (320). The feedthrough plate (300) is typically bonded to the distribution substrate (310). The reaction cell plate (320) is typically removably fitted to the underside of the distribution substrate (310), or the underside of intermediate plate interposed between the distribution substrate (310) and the reaction cell plate (320). The capillary barriers (370) and sluices created by the second openings (362) or third openings act as a combined valve and pump. The capillary barriers (370) prevent flow to the reaction cell, which flow would be favored by capillary forces, until the first pumps (360) or second pumps (361) provide the extra pressure needed to overcome the capillary barriers (370). Narrowing the sluices can increase the capillary forces favoring flow, thereby reducing the amount of added pressure needed to overcome the capillary barriers (370). The use of the capillary barriers (370) allows flow control to be governed by the first pumps (360) or second pumps (361), which are typically controlled by controller.

Abstract: In the case of the present method for identifying a gas leak (32) between the anode and cathode gas areas (4 and 6, respectively) of a PEM fuel cell (2), a cell voltage is detected, and the anode and cathode gas areas (4 and 6, respectively) are purged with nitrogen (N2) in a first time period, the cathode gas area (6) is filled with oxygen (O2) and the anode gas area (4) is filled with hydrogen (H2) in a second time period, and the drop in the cell voltage below a limit value as a function of time is then measured and evaluated. This measure ensures reliable identification of the gas leak (32).
