Title: Axial flux motor and generator assemblies
Inventor: CROCKER TIMOTHY RICHARD
IPC: H01F38/18
Filed: 2008-12-18
Abstract: An axial flux motor assembly 10 comprises a stack of first rotor and second stator discs 20a, 20b arranged alternately such that there is a gap allowing. The first and second discs 20a, 20b each comprise sectors 200 of magnetic material arranged on a face of the disc 20a, 20b, between each of which sectors 200 is a radially-extending conductor of a conductive path 201 for conducting electric current (fig 12a). The sectors 200 of magnetic material are arranged at a constant angular pitch, but the pitch of the sectors on the first disc may be different from the second disc. When electric current flows in the conductors 202', 202" magnetic flux runs perpendicular to the faces of the discs 20a, 20b in axially-extending flux paths 220, such that, considering the first disc(s) independently of the second disc(s), the magnetic flux in one axially-extending flux path runs in an opposite direction to that in the immediately-adjacent flux paths on each side of it, and is returned by flux return portions 30 of magnetic material provided at each end of the assembly 10. The total flux is the super-position of the flux of the first disc(s) and the second disc(s). Switching circuitry 50 (fig 8) is disclosed. A rotary transformer (fig 19) may be used to supply current to the rotating disc and the associated circuitry (fig 20) is described.

Title: Secure memory device with wide area communications
Inventor: SHAW NORMAN
IPC: G06F21/88
Filed: 2009-03-30
Abstract: A controller is configured to control access to a data store on a security and communications device connectable to a computer with a housing; a data store; a wide area communications device. The software enables the memory device, such as a USB, to control the wide area communication device to transmit a security message to a remote monitoring system in response to an access event. The security software verifies the presence of the secure memory device and, in the event that the presence of the security and communications device cannot be verified, inhibits operation of the computer. The device may include location sensing means such as GPS or GSM mobile location, which is used to block access to encrypted data on the device when the computer is not at an authorized location. The access event may be powering up or down, reading, writing or deleting data from the device. The security software may poll the device to verify it, with a secure message being sent to a remote monitoring station, with a secure handshake taking place.

Title: Peer to peer managed file transfer
Inventor: THOMAS PETER KINGSTON
IPC: H04L29/08
Filed: 2009-06-15
Abstract: A method for establishing a secure communications data stream between two remote computers for the immediate and direct transfer of an encrypted data file without the need for either of the remote computers to establish a server style inbound listening connection. The data stream is managed by a central server which can dynamically determine if the recipient computer is currently on-line and available to receive the connection. If so, the data is streamed between the sender and the recipient through the central server to allow control and status tracking information to be maintained but without any of the data being stored on the central server. If the recipient computer is not on-line, the central server stores the (encrypted) data for immediate delivery once the recipient computer comes on-line. X.509 certificates may be used to create a session key used for the encrypted file transfer. Digital signatures for the file may also be used to verify correct receipt of the file by the recipient and to generate a return signature to provide proof of delivery to the sender. Notifications may also be used such that the sender client notifies the server of the desire to send a file to the recipient peer and sends the file when the recipient peer has indicated that it is ready to receive the file.

Title: Post airbag deployment protective extraction of substances
Inventor: GREEN JEREMY ROSS
IPC: B08B5/04
Filed: 2009-12-15
Abstract: The invention relates to automotive airbags and post deployment protection. An airbag gas, chemical and debris extraction system utilises the vehicle's airbag control unit (ACU) and air distribution system to evacuate harmful gas, chemicals and debris vented into the occupant environment by the deployment of the airbags. Deployed airbags AB1-AB8 vent gases, chemicals and debris represented by cloud (G) into the occupant environment. The airbag control unit (ACU) sends a signal to the HVAC system (H), this increases the Fan Speed to it maximum (HM) and reverses the air flow direction of the system. The gases, chemicals and debris represented by cloud (G) are evacuated through the HVAC system in the direction of the arrows and vented externally through the system intake (I1).

Title: Improvements in or relating to production of tetrafluoroethylene
IPC: C07C17/00
Filed: 1951-05-04
Abstract: Tetrafluoroethylene, CF2=CF2, is prepared by a process which comprises sufficiently heating an anhydrous mixture of an alkali metal trifluoroacetate salt and an alkali metal hydroxide to initiate an exothermic reaction and allowing it to continue with the formation of CF2=CF2 as the dominant carbon-fluorine reaction product and recovering the latter.  The temperature for initiating the reaction is about 200 DEG  C.  The salt-base mixture may be dehydrated by heating.  In one example an aqueous solution of sodium trifluoroacetate and sodium hydroxide is evaporated and dried at 120 DEG  C.  On heating the dried residue to 270 DEG  C. the temperature of the reaction mixture suddenly rises and a mixture of carbon dioxide and tetrafluoroethylene is evolved.  In a similar example the dried residue is placed in a tube in a furnace heated to 225 DEG  C. and the tube is withdrawn when the reaction commences.  The reaction products are condensed in a liquid air-cooled trap and include carbon dioxide, tetrafluorethylene, trifluoroacetyl fluoride and fluoroform. In controlling the reaction inert diluents, such as fluorocarbon compound liquids and finely-divided inert solids with the provision for the transfer of heat from the reaction zone may be used with controlled feeding of the starting material into the reaction zone. The tetrafluoroethylene may be recovered from the gaseous product mixture by chemical and fractional separation procedures.  It is stated to be known that the pyrolysis of metal trifluoroacetates yields degradation products which are not fluorocarbons.
