Title: Decoding a spectrally modulated light signal
Inventor: JOHNSTON JAMES STEWART
IPC: G01L11/02
Filed: 1991-07-30
Abstract: To analyse a spectrally modulated light signal from an inteferometric transducer (1), the value of an optical path difference associated with a parameter to be remotely sensed, such as pressure, is encoded as a characteristic frequency of spectral modulation of the light. The light intensity is measured at a number of wavelengths within a selected range to obtain measured spectrum. Reference data is generated to represent a theoretical spectrum corresponding to a nominal optical path difference, the reference data being generated for a greater range of wavelengths than the measured spectrum. The measured spectrum is correlated with successive portions of the reference data to identify a portion of the reference data exhibiting correlation, and an output signal is generated which is representative of the location of the correlating portion of the reference data. <IMAGE>

Title: Flow control valve
Inventor: GATES ERIC
IPC: F16K47/08
Filed: 1993-05-05
Abstract: A valve comprises a plug 3 which is movable within an apertured sleeve so as to open or close (depending on the direction of plug movement) apertures therein. The plug has a seating surface 18s which is provided behind a flange 19 which acts as a shroud to protect the seating surface from the main flow stream. The seating surface 18s locates on a seat 23 which is again positioned outside the main flow stream. The seating surface 18s and the seat 23 are protected against erosion by particulate matter contained in fluid entering the valve. Additionally, the plug has a nose (13) which provides two effects. Firstly, the nose causes fluid to be deflected along the central axis of the sleeve thus reducing the possibility of internal erosion. Secondly, an axial passage through the plug to the nose causes a reduced pressure to be generated in a space (11) behind the plug. As a result, the surfaces within this space are continuously scavenged thus preventing particulate debris building up behind the plug. <IMAGE>
