Title: Superfine powder and spraying
Inventor: CHANDLER P E
IPC: C23C4/12
Filed: 2002-08-28
Abstract: A method of manufacturing powder and coatings uses superfine powder particles in which the superfine powder is first agglomerated into particles of a size suitable for flowing through a powder feeder but in such a way that the particles self atomise during the spraying process. Thus superfine particles can be sprayed without the normal problems of the powder jamming up the powder feeder. The agglomeratron is carried out by first mixing the powder with a binder and then spray dried at controlled furnace temperatures, below the sintering temperature of the constituents, so that it is both robust and easily breaks up into the component superfine powders when heated inside the spray torch. The superfine powder has a size of less than 5 microns. The agglomerated powder is fed together with fuel to a spray torch where it is heated and accelerated.

The encrypted content may be freely transferred and stored without copyright concerns since the decryption key is generated by the smart card containing the license.
Patent GB-2383909-A (GB)
Title: A common-mode frequency compensation arrangement for a low-noise differential amplifier
Inventor: RENOUS CLAUDE
IPC: H03F1/08
Filed: 2002-12-11
Abstract: A differential amplifier arrangement comprises a pair of amplifying followers 410 and 420 compensated by Miller capacitors 411,421 coupled around the output stages of the amplifiers. To avoid common-mode oscillation, the output common-mode voltage is derived from resistors 491 and 492 then buffered and fed back through capacitors 412 and 422 to the input side of the Miller capacitors, which can be made smaller because they are augmented by 412 and 422 in respect of common-mode signals. Loop gain is higher for common-mode signals than for differential-mode signals and so the effective compensating capacitance must be higher for CM signals. The lower Miller capacitance allows greater amplifier bandwidth. The buffer 470 and resistors 491,492 may be replaced by a purely capacitive network (figure 6).

Title: Rapid characterisation of lithology at the head of a drilling tool
Inventor: REZGUI FADHEL
IPC: E21B49/00
Filed: 2003-05-01
Abstract: The nature of the formation 11 at the bottom of well 8 is determined as the well is drilled by taking measurements of the drilling fluid inside 22 and outside 24 of the drillstring 2. Differences between the pairs of measurements reflect interaction between the formation and the drilling fluid. Sensors 26 measure one or more physicochemical properties of the drilling fluid in the drillstring and sensors 28 measure the same properties as the fluid circulates back up the borehole. Both sets of sensors are located close to the drilling tool 14 to minimise the time delay between drilling across a change in lithology and the change being detected. Communication device 10 transmits the measurements to a receiver 16 at the surface. Tertiary sensors 30 may also be located close to the drilling tool to survey the drilled formations directly. Predetermined charts can be used to allow rapid classification of each new formation encountered.
