Patent GB-2125429-A (GB)
Title: Tar removal process
Inventor: BROWN FRANK CLIFFORD
IPC: C10J3/84
Filed: 1983-08-03
Abstract: A process for removing tar from the gaseous products of the thermal treatment of a carbonaceous material, which process comprises cooling the products to a temperature sufficiently high to keep essentially all of the water vapour present therein in the vapour phase, but sufficiently low to condense out at least a major portion of the tar therein, and then separating the condensed tar from the gaseous products without essentially any condensation of water. Preferably the condensed tar is separated by scrubbing the cooled products with a tar-containing liquid stream, which stream is maintained during scrubbing at a temperature sufficiently high to prevent the condensation of water. The process is particularly applicable for the gasification of coal.

Patent GB-2141541-A (GB)
Title: Optical transducers
Inventor: BROWN HAROLD THOMAS
IPC: G01K1/02
Filed: 1984-06-13
Abstract: An optical analogue transducer for measuring changes in a variable parameter such as pressure, temperature or flow rate by wavelength modulation employs a variable filter 3 which select a pass band from incident optical signals and varies the centre wavelength of the pass band in response to a change in the measured variable. The shift in the centre wavelength of the pass band corresponding changes in intensity in a narrow band selected from within the pass band. Compensation for transmission losses is made either by directing light through beam container 25 alternately from two sources 1 and 2 emitting narrow wavelength bands on opposite sides of the centre frequency of the filter 3, or by using a broadband source and two detectors having different wavelength responses. Light from the sources passes through optical fibre 8 to an interference filter 3 which rotates on movement of a Bourdon tube 16. Reflected light passes through another optical fibre 9 to detector 4. Source intensity variation may be compensated by a separate detection system 23 to 27. <IMAGE>
