Patent CA-2311877-A1 (CA)
Title: Air-conditioning system for below-deck areas of a passenger aircraft
Inventor: MARKWART MICHAEL
IPC: B64C13/08
Filed: 2000-06-16
Abstract: An aircraft air-conditioning system provides ventilation, air--conditioning and fire protection for a below-deck stairwell and cargo hold that may be equipped with passenger sleeping compartment containers. An air mixing unit mixes fresh air and recycled air to supply mixed air through a first supply air main line and a supply air unit into the freight hold, and through a second supply air main line into the stairwell. A trimming air unit provides hot bleed air from the aircraft engines into the mixed air supplied through the first and second supply air main lines. An exhaust air line extracts exhaust air from the freight hold, while an exhaust air supplemental line extracts exhaust air from the stairwell, both of which are connected to an exhaust air main line with an exhaust air ventilator that blows the exhaust air overboard. A bypass line provides bypass air if needed for the demands of the ventilator. Regulating valves and non-return flap valves in the supply air line and in the exhaust air line regu-late the flow of air and prevent back-flow. Temperature sensors are connected to a controller that regulates the temperature of the mixed supply air to achieve a comfortable temperature in the freight hold and in the stairwell. In the event of fire, the air valves are closed, to seal-off the freight hold and prevent the spread of smoke into the stairwell or other ventilated areas.

Title: Electrostatic processing chamber arranged in electrostatic flocking apparatus and electrostatic coating apparatus
Inventor: ABE MASAAKI
IPC: B05B5/08
Filed: 2000-08-21
Abstract: In order to obtain an evenly flocked and an evenly coated surface of a strip-like elongated workpiece, any slack of the strip-like elongated workpiece is removed not to affect the workpiece when the workpiece travels through an electrostatic flocking and an electrostatic coating chamber at high speed. A slack of the workpiece occurs due to its own weight under the influence of gravity when the workpiece travels through the electrostatic flocking and the electrostatic coating chamber at high speed. A V-shaped oblique surface portion of the workpiece is forcibly defined by a pressure roller in a position corresponding to that of the slack of the strip-like elongated workpiece. An electrode is disposed in parallel to the workpiece's V-shaped oblique surface portion defined by the pressure roller.

Title: Flexible method of security data backup
Inventor: HILLHOUSE ROBERT D
IPC: G06F12/16
Filed: 2000-09-01
Abstract: A method of supporting a substantially secure backup copy of a key-server database, said database comprising security information specific to a plurality of users, absent the need for a duplicate key-server is disclosed. According to the method, each individual's security data is stored within the key-server database and is also stored on a portable data storage device, such as a smart card or a PCMCIA token. If the key-server crashes and the database stored thereon is lost, a duplicate key-server database is reconstructed using the aggregate of the partial database files stored on each individual's portable data storage device. Similarly, when a portable data storage device is lost, it can be rebuilt from the data stored within the key-server.

Title: Method and flow control device for delivering fuel oil to a low firing rate fuel oil burner
Inventor: WYMASTER NOEL A
IPC: F23D11/36
Filed: 2001-01-29
Abstract: A method for delivering fuel oil from a pressurized fuel oil source to an airblast atomizer subassembly on a low firing rate fuel oil burner includes providing a flow control device having a body defining a bore extending between and inlet end of the bore and an outlet end of the bore. The flow control device includes a rod disposed coaxially within the bore in a close fitting relationship. At least one of the bore and the rod is threaded (i.e., includes a groove extending along a helical path) to define a passageway extending along a circuitous, helical path intermediate the input and output ends of the bore through which the fuel oil must pass in flowing from the input end to the output end. The passageway has a size and shape adapted to achieve a desired rate of flow of the fuel oil to the airblast atomizer subassembly (e.g., less than 1.0 gallons per hour and typically less than 0.5 gallons per hour). The method proceeds by delivering the fuel oil through the passageway in the flow control device. One embodiment of the flow control device has a threaded bore. Another has a threaded rod. Yet another is adapted to attach directly to the atomizer subassembly, while still another has fittings enabling placement in a fuel oil line apart from the atomizer subassembly.

Patent CA-2341077-A1 (CA)
Title: A driving scheme for liquid crystal displays
Inventor: YEUNG STEVE WAI LEUNG
IPC: G02F1/133
Filed: 2001-03-19
Abstract: The invention relates to a m-column/n-row/m x n-pixel inversion driving method fur a liquid crystal display where m can be any integer from two to the number of scan lines and n can be any integer of two to the number of column lines.  Such a driving method  greatly reduce total fringe field effect on display to maintain contrast whilst minimising perception of flickering. Moreover, the number of inversions can be adjusted to strike a balance between contrast and perceptibility of flickering. The n-row inversion method can be applied to passively and actively driven liquid crystal displays where n can be any integer from two to the number of scan lines. The m-column inversion driving method can be applied to an actively driven LCD where m can be any integer from two to the number of column lines while the n x m-pixel inversion method can be applied to an actively driven LCD where n can be any integer from two to the number of scan lines and m can be any integer from two to the number of column lines. This inversion method is particularly useful in actively driven miniature TFT and reflective liquid crystal on silicone displays in contrast to the effect on fringe field if a conventional single row/column/pixel inversion method is used.
