Title: Electrostatic air filter
Inventor: AMESS COLIN LAWRENCE
IPC: B03C3/16
Filed: 2003-12-23
Abstract: An electrostatic air filter for separating very small air borne contaminants including chemical particles, dust or biological organisms from the air or gas in which they are carried. The filter comprises a duct, chamber or pipe to import and transport the air or gas as well as to house an electrostatic filter mechanism. The filter provides a particle charging means 1, an optional means to introduce atomized liquids 12 and a capture means 3 of collecting very small particles and recovering any atomized liquids by the use of a maze of fine wire or filament conductors 20 held at a high voltage. The particle charging means comprises a fine wire 10 held at a high positive potential relative to plates 11. Dust is charged as it passes and combines with liquid droplets in the atomizer. In the capture means the droplets migrate to the fine wire where droplets and their captured particles drip into a collection chamber. Any remaining charged particles pass through an earthing stage 4 as a final filter and charge neutraliser. A fan 6 draws the air through the duct. The capture means may be rotated or may include a cyclonic arrangement. (Not shown).

Title: Multilayer expandable tubular
Inventor: STEELE DAVID J
IPC: E21B43/10
Filed: 2004-01-20
Abstract: An expandable tubular (16) is formed from a number of layers (50, 52, 54, 56) in such a way that relative displacement can occur between the layers (50, 52, 54, 56) as the tubular (16) is expanded. Following expansion, relative displacement between the layers (50, 52, 54, 56) is prevented, possibly by mechanically interlocking (fig 7) the layers (50, 52, 54, 56), chemically bonding (fig 9) the layers (50, 52, 54, 56) to each other, or by use of an adhesive (fig 10).

Title: Modular architecture for a network storage controller
Inventor: PECONE VICTOR KEY
IPC: G06F12/00
Filed: 2002-09-26
Abstract: A network storage controller for transferring data between a host computer and a storage device, such as a redundant array of inexpensive disks (RAID), is disclosed. The network storage controller includes at least one channel interface module which is connected to a passive backplane, and selectively transfers data between the host computer and storage device and the passive backplane. The network storage controller also includes at least one controller memory module (104, 108), which communicates with the channel interface module (136, 140) via passive backplane (116), and processes and temporarily stores data received from the host computer or storage device. In applications where redundancy is required, at least two controller memory modules and two channel interface modules are used. The controller memory modules may mirror data between one another using the passive backplane and a shared communication path on the channel interface modules, thereby substantially avoiding the use of host or disk channels to mirror data.

Title: Emergency lighting appliance having ON-OFF switching when supplied by mains electricity
Inventor: KUO CHAO-TUNG
IPC: H02J9/06
Filed: 2005-01-18
Abstract: An emergency lighting appliance comprises a fluorescent lamp tube (1), a controller (2), a mains power circuit (3) capable of processing mains electricity for lighting and a backup circuit (4) that provides for a reserve power source. By integrating these devices, renovation of existent wiring is not required for installation. When mains electricity is normally supplied, an ON-OFF switching approach controls the illumination and extinguishing of fluorescent lamps, but during mains electricity failure, the power circuit automatically shifts to the backup circuit (4) that provides reserve power to provide for emergency lighting. Furthermore, when mains electricity supply is restored, the power circuit is automatically shifted to the mains power circuit (3) such that ordinary lighting function is once again reliant on mains electricity.

Title: Facilitating and authenticating transactions using a SIM
Inventor: KORAICHI NAJIB
IPC: G06Q20/00
Filed: 2005-04-14
Abstract: A computer, such as a Windows-based PC 23, has associated with it a Subscriber Identity Module (SIM) 15, such as of the type used in a GSM or UMTS cellular or mobile telecommunications network. The SIM 23 can be authenticated with the network 3 in the same way as for authenticating SIMs of mobile telephone handsets used in the network, and can in this way authenticate the user of the PC 23 or the PC 23 itself. Such authentication can, for example, permit use of the PC 23 in relation to a particular application running on the PC 23. Challenge and response messages are transmitted between the network 3 and the SIM 15 via an authenticator module 30 implemented on the PC 23. These authentication messages have the predetermined format of an Over The Air (OTA) message, which is also used in GSM or UMTS telecommunications networks to transmit non-authentication messages - for example, SMS messages. The authentication data is encapsulated within OTA messages. The OTA messages are not necessarily transmitted wirelessly (that is, over the air). They may be transmitted via a fixed network; however, they have the predetermined format of OTA messages.

Title: Comparator for circuit testing
Inventor: LESLIE TOM
IPC: G01R31/317
Filed: 2005-06-13
Abstract: A test signal INPUT is fed directly to a first input of a comparator having hysteresis, and to a second input of the comparator through a delay circuit so that an input is compared with a delayed version of itself. The hysteretic comparator is thereby self referencing and edge sensitive and enables AC coupled signals to be detected. The comparator state may be initialized by inputs StateA and StateB and may be switched to a level sensitive mode in which the second input is compared to a reference level. The comparator may be incorporated into an integrated circuit and used for JTAG testing, and in accordance with IEEE  õ  standards: IEEE 1149.1 and IEEE 1149.6.

Filed: 2005-08-30
Abstract: Disclosed is a high-pressure generation apparatus, which comprises a pair of columnar-shaped anvils 2 disposed in opposed relation to one another to define a pressure-generating space therebetween. The anvils are adapted to be applied with a load therebetween to generate a high pressure in the pressure-generating space.

Title: Redundant arrangements of superconducting switches
Inventor: MCGREGOR ROBERT JAMES
IPC: H01F6/00
Filed: 2006-05-22
Abstract: A composite superconducting switch comprising two or more redundant superconducting switches 3 connected in parallel and controlled by switching means 4 is provided. The arrangement allows the distribution of current between switches to be controlled and for current conduction to be maintained by standby switches in the event that a (main) switch is turned off in response to being quenched.

The switches 3 and variable resistances 8 can be controlled by switching means 4 under the action of an external controller. All of the switches are able to support the full load current without quenching. The switches can be switched off periodically to minimise the risk of quenching. Alternatively a single fixed resistance (6, fig 2) may be provided in series with an auxiliary superconducting switch through which current flows when a main superconducting switch is quenched.
