Title: Distributed optical fibre measurements
Inventor: HARTOG ARTHUR H
IPC: G01K11/32
Filed: 2004-03-31
Abstract: A method of obtaining a distributed measurement comprises deploying an optical fibre in a measurement region of interest, and launching into it a first optical signal at a first wavelength .lambda.0 and a high power level, a second optical signal at a second wavelength .lambda.-1, and a third optical signal at the first wavelength .lambda.0 and a low power level. These optical signals generate backscattered light at the second wavelength .lambda.-1 arising from Raman scattering of the first optical signal which is indicative of a parameter to be measured, at the first wavelength .lambda.0 arising from Rayleigh scattering of the first optical signal, at the second wavelength .lambda.-1 arising from Rayleigh scattering of the second optical signal, and at the first wavelength .lambda.0 arising from Rayleigh scattering of the third optical signal. The backscattered light is detected to generate four output signals, and a final output signal is derived by normalising the Raman scattering signal to a function derived from the three Rayleigh scattering signals, which removes the effects of wavelength-dependent and nonlinear loss.

Title: Stable 5,10-methylene-tetrahydrofolate pharmaceutical compounds
Inventor: AMMANN THOMAS
IPC: A61K31/00
Filed: 2004-06-28
Abstract: The invention relates to 5,10-methylene-(6R)-,-(6S)-or (6R,S)-tetrahydrofola te (MTHF) pharmaceutical compounds whose stability is due to the adjustment thereof to a basic pH value and to a simultaneous citrate use. Said stabilisation is self-producible in the absence of a reducing agent. Said invention is particularly suitable for preparing lyophilization solution or lyophilisates or dry powders and dry mixtures since the stable MTHF solution s can be filled at the high concentration thereof into corresponding recipient s like, for example vials, ampoules etc. Said lyophilisates are surpassingly storable and stable. They are easily reconstituted by adding water or aqueou s solutions, thereby providing diluted injection solutions ready for use with an excellent stability. Said invention also makes it possible to produce highly concentrated calcium or acid MTHF salts, even difficult-to-dissolve, in the form of isotonic physiologically compatible solutions.
