Patent GB-2442824-A (GB)
Title: Apparatus for diffusion dying a 3D surface and for vacuum forming
Inventor: VIGG PETER AUSTEN
IPC: B41M5/382
Filed: 2007-07-30
Abstract: The apparatus preferably comprises an infinitely variable speed fan 11 providing hot air flow at a low speed or Reynolds number to soften a film, and at a high speed or Reynolds number for dye diffusion. In the preferred embodiment, heaters (8, electric or 9, gas) are modulated to maintain air in an enclosure (acting as a hot air reservoir) between 160 and 260 degrees centigrade. Film 6, which may carry a dye, is mounted onto frame 5 on movable carriage 1a above workpiece (if dying) or former (if vacuum forming) 3. The carriage is then moved under chamber 12a, shutter 7 withdrawn and fan speed reduced to heat, soften and dry the film. The vacuum platen is then raised to seal around the film, and apply vacuum to form the film around the workpiece or former. The fan speed is then increased while dye is being transferred to the workpiece. The shutter then returns and the dyed or moulded component is removed when the carriage is returned to its starting point. The component may be removed following a cooling period. Compressed air may be used to remove the film.

Title: Suction surface profile for a gas turbine engine transonic fan blade
Inventor: WILSON MARK JAMES
IPC: F04D29/38
Filed: 2007-10-17
Abstract: The suction surface blade angle 30 of a transonic fan blade 12, subject in use to a shock wave 22 associated with the leading edge of an adjacent fan blade, progressively reduces along part of the suction surface 18, beginning at a position upstream of the shock wave position. Forward of the position at which the reducing blade angle starts the suction surface may have zero or negative curvature so as to provide precompression of the air flow. The increased area variation at the location of the shock results in the shock position becoming less sensitive to small geometric imperfections which reduces shock sensitivity and variation in aerodynamic load and hence reduces the untwist variation. This has the effect of stabilising the untwist deflections of the fan. The blade is suitable for use in a gas turbine engine.

Title: Hybrid power with, or without a battery pack
Inventor: BAYRAM PETER JOHN
IPC: B60L50/16
Filed: 2008-04-03
Abstract: Positive displacement supercharger 3 acts as an expander when braked and speed-controlled by generator-motor 6, throttling intake air drawn in by vacuum pressure and/or blown in by turbocharger(s) via intake 2. This air exerts a rotational force on the rotor lobes of supercharger 3 causing it to output power via belt drive 5 to variable speed generator-motor 6, which is speed controlled by an electronic throttle system varying the speed of supercharger 3 via belt drive 5. Mechanical power input to generator-motor 6 is electrically transmitted to motor-generator 9 that outputs mechanical power via belt drive 10 to engine crank pulley 11 such that battery-pack charging/discharging losses are obviated. Supercharger overrun braking/coasting power can be recovered via a battery-pack. Intercooled turbocharged air 2 and/ or vacuum intake air is expansion cooled/refrigerated by supercharger 3. Power transmission can be reversed, increasing acceleration/throttle response, by varying a motor-generators' nominal speed relative to its actual speed. Motor-generator 9 starts engine 1 via battery 12.
