Title: A steering apparatus for a steerable drilling tool
Inventor: LIMITED SONDEX
IPC: E21B17/00
Filed: 2005-05-06
Abstract: An apparatus is described for steering the drill bit of a borehole drilling tool. The apparatus comprises an outer sleeve 30 having an eccentrically located bore 34 which houses a rotatable cam 36. The cam also has an eccentrically located bore 42 housing a mandrel connected to a drill shaft. The eccentricity of the bores in the cam and the outer sleeve are the same, such that by rotation of the cam within the sleeve, the axis of rotation for the mandrel can be moved from the central axis 100 of the borehole being drilled to a position displaced from it 102. In the displaced position, rotation of the mandrel and the drill shaft cause the borehole to curve. Rotation of the cam with respect to the sleeve is arranged by providing a stop 52 in the mandrel which picks up ratchets 46 or 48 of the cam depending on the direction of rotation. Stop 40 and stop 52 limit the rotation of the cam so that straight ahead drilling and deviated drilling can be performed.

Title: Controlling audio reproduction in a receiver by means of broadcast program type codes
Inventor: BANKS NICK
IPC: H04H20/00
Filed: 2005-05-11
Abstract: A receiver, for example a DAB or DRM receiver or an RDS equipped FM radio, includes a decoder 7 for decoding programme type (Pty) information which is broadcast along with the audio programme material. The Pty codes may control an audio equaliser 4 (fig. 1). The equaliser parameters may be pre-defined or set by the user, and are automatically deployed when pre-defined Pty information is received. In a preferred embodiment (fig.2), the decoded Pty information directly adjusts the coefficients or scale factors of the individual frequencies or sub-bands in the audio decoder 3. The decoder 3 could be an MPEG-1 layer 2 or layer 3 codec. The invention finds particular application for in-car or vehicle receivers.

Abstract: A mainshaft assembly for a gearbox is disclosed. The mainshaft (44) comprises several gears (30, 32, 34, 36) all arranged coaxially on the mainshaft. The assembly comprises first and second hubs (50, 52), each being associated with a respective drive gear. The hubs having dog rings (54, 56) operable to selectively couple with the drive gear. A drive connection comprising a cage (42) and rollers (60) is associated with each hub and operative to connect or disconnect the hub to the mainshaft. Upon connection of first and second hub by their dog rings, the drive connection connects one of the hubs the mainshaft when torque is applied to the mainshaft in a first direction. When torque is applied in opposite direction the second hub engages the mainshaft. This enables selection of gear without delay during engagement and disengagement of drive gears.

Abstract: Apparatus for sterilisation and/or destruction of biological contaminants present on a surface, the apparatus comprising a base unit 10 to which is attached a flexible cable 16 connected at its distal end to an optical assembly or head 18. In use, the optical head is arranged adjacent a surface 20 to be sterilised. The apparatus is then operated to transmit light energy onto the surface to effect sterilisation and/or destruction of biological contaminants present thereon. The light delivered is preferably in the ultra-violet region (200-400nm). The apparatus may include a power supply or a pulser 12 so that the light energy delivered is pulsed according to a predetermined regime. The power supply unit may convert AC mains voltage to high voltage DC (24, Fig. 2). The power supply unit 12 may house a pulse forming network (26, Fig. 2) including a capacitor. The DC output is used to charge the capacitor which remains charged until the user is ready to treat the surface. When the user pulses the optical output, the energy stored in the capacitor is delivered to flashlamp (18, Fig. 2) and converted into optical energy. A method of sterilising a surface comprising arranging the optical assembly adjacent a surface and operating the device to transmit light energy onto the surface is also claimed.

IPC: F02C7/36
Filed: 2006-08-10
Abstract: An arrangement for taking power from the main shafts 18, 20 of a gas turbine engine comprises a hydraulic coupling 52. At high engine speeds, the coupling is disengaged and power is only taken from the high pressure spool 20. At low speeds, the coupling is engaged to allow power to be additionally taken from the intermediate pressure spool.

Title: Maintaining user sessions started with content from a first version of a website whilst forwarding new user sessions to a second version of the website
Inventor: HOWE SIMON
IPC: G06F17/30
Filed: 2008-03-17
Abstract: A system provided with a traffic management server 14 for providing access to an information system (eg website) comprising a plurality of instances 102,104 which exist in parallel during a transition from one version of the website content 102 to a second version 104. The traffic management server identifies the session to which each request (in the form of URI) from a user 22, 23 belongs, for example using cookies written to each user's browser. Prior the transition, the traffic management server forwards to the first instance each request that is the first request in a session; following the transition, the request processor is arranged to forward to the second instance each request that is the first request in a session. After the transition the traffic management server forwards to the second instance each request associated with a session for which a user request has previously been forwarded to the second instance while continuing to forward to the first instance each request associated with a session for which a request has previously been forwarded to the first instance. This allows existing users 22 to continue accessing the content existing when they begun their session whilst new users 23 are directed to the updated content. This arrangement may continue for a set time period after the transition. The traffic management server may also be arranged to forward to the second instance each request associated with a session for which a user request has previously been forwarded to the second instance prior to the transition thereby allowing support teams access to any of the instances.
