Title: Motor opened ventilator fan doors
Inventor: YIP CHUNG LUN
IPC: F04D29/52
Filed: 2000-12-14
Abstract: Window mounted exhaust fan comprises a casing having front 11 and rear 12 faces and an air passage therebetween having electric motor 18 driving fan 15. At the front face are two oppositely rotating pivoted doors 14, 15 rotationally linked by integral gears 14a, 15b and to second, opening motor 24 via further integral gears 14A, 15B and gear 23. A switching circuit (Fig. 3) is arranged such that when the fan is turned on, the second motor opens the doors and then stops. The second motor is a reversing motor so that when the fan is turned off the second motor starts, reverses, closes the doors and then stops. Removes the need for a solenoid to hold slatted doors open while the fan runs. Drain hole 16 removes any water collected by the open lower door. The doors may also be spring biassed shut.

Title: Method and apparatus for controlling the temperature within an electrochemical fuel cell
Inventor: WILKINSON DAVID P
IPC: H01M8/04
Filed: 1999-11-29
Abstract: A method of controlling the temperature within an electrochemical fuel cell stack (10) comprises introducing a reactant fluid stream (34) comprising both a heat transfer liquid (42) and a reactant (32) into a fuel cell assembly such that the reactant fluid stream contacts an electrode (22). The heat transfer liquid is other than water. Preferably, the method further comprises recirculating heat transfer liquid which is in the reactant exhaust stream, typically via a heat exchanger, and re-introducing it into the fuel cell assembly in the reactant fluid stream. The recirculated heat transfer liquid may be directed to a reservoir which in turn supplies heat transfer liquid to the reactant fluid stream as it is needed. In a further embodiment, the method may comprise using the heat transfer liquid to heat a fuel cell stack to a desired operating temperature rather than cooling the stack.

Abstract: A respirator comprising a face piece (1) with primary sealing means (6) thereon to make a seal with a wearer's face. The face piece (1) has a viewing window (2) therein and an oro-nasal mask (7) mounted in the interior thereof having an inlet (9) for inhalate and an outlet (10) for exhalate both having a one-way valve therein. The oro-nasal mask (7) also has secondary sealing means (8) thereon to make a seal with the wearer's face around the nose and mouth region. The primary sealing means (6) extends around the face piece (1) and makes a seal with the wearer's face around the eyes (3), nose (4) and mouth region (5) but above the wearer's chin. The secondary sealing means (8) also contacts the wearer's face in the chin region but above the location where the primary sealing means (6) is in contact therewith. The face piece (1) is releasably attached to the wearer's helmet (16) by wires (12) which retain the face piece (1) in a fixed position relative to the wearer's face. In use, when pressurised breathable gas is supplied to the interior of the face piece (1) through inlet (11), the primary sealing means (6) expand and contract and move relative to the wearer's face to automatically maintain the seal therewith regardless of the pressure of the breathable gas supplied to the interior of the face piece (1).

Title: Method of preventing gas breakthrough in an oil bearing formation
Inventor: METCALF ARTHUR STEVEN
IPC: C09K8/44
Filed: 2001-09-05
Abstract: A method of preventing gas breakthrough in an oil well, which includes first pumping a slug of an alkaline earth salt into the well bore, followed by a slug of spacer solution, and finally a slug of a fatty acid resin.

Title: Mass spectrometer and control means for comparing samples
Inventor: BATEMAN ROBERT HAROLD
IPC: G01N27/62
Filed: 2003-06-12
Abstract: A method of mass spectrometry is disclosed wherein a gas collision cell is repeatedly switched between a fragmentation and a non-fragmentation mode. Parent ions from a first sample are passed through the collision cell and parent ion mass spectra and fragmentation ion mass spectra are obtained. Parent ions from a second sample are then passed through the collision cell and a second set of parent ion mass spectra and fragmentation ion mass spectra are obtained. The mass spectra are then compared and if either certain parent ions or certain fragmentation ions in the two samples are expressed differently then further analysis is performed to seek to identify the ions which are expressed differently in the two different samples.

Title: Elastic latch for portable electronic apparatus
Inventor: LEE MING CHANG
IPC: G06F1/16
Filed: 2003-07-11
Abstract: The invention relates to a latch device for engaging with a keyboard 110 within a housing 130 of a portable electronic apparatus. The latch device includes a support 210, a latch 230, and a saw-toothed elastic strip 251. The support is connected with the housing, and a portion of the latch stretches out from the housing to engage with the keyboard. Two ends of the first saw-toothed elastic strip connect respectively with the support and the latch. The latch moves relatively toward the support by using the first saw-toothed elastic strip. The keyboard can be detached from the housing when an external force presses the latch into the housing. Moreover, because of the deformation of the first saw-toothed elastic strip, the first saw-toothed elastic strip provides a recovering force to press a portion of the latch out of the housing. A second strip can be provided on the other side of the latch (fig. 2a) or an arcuate strip can have both ends engaged with the latch.

Title: Operating a computing device comprising NAND flash memory
Inventor: SYMBIAN LTD
IPC: G06F9/445
Filed: 2003-08-01
Abstract: A method of operating a computing device having NAND flash memory for storage of program code and user data. At start up, only selected components of the computing device core operating system are shadowed into RAM. Other components, such as read only system files associated with the core operating system, are retained in the NAND flash memory and only shadowed into RAM upon demand. The program codes shadowed into RAM at start up and the program codes shadowed into RAM upon demand are presented to a file server of the computing device as a composite file system. The use of the composite file system reduces the amount of RAM permanently occupied by core operating system code during operation of the device and also enhances the use of the more power efficient NAND flash memory. Moreover, the boot up time of the device is also significantly reduced.
