Patent EP-0419167-A1 (EP)
Inventor: SCHMIDT HANNS-LUDWIG
IPC: G01N30/06
Filed: 1990-09-17
Abstract: The invention comprises an on-line mass spectrometric method and apparatus for the determination of the isotopic composition of at least oxygen, hydrogen and nitrogen in a compound or mixture of compounds. A mixture contained in syringe 6 is injected through injector 7 on a chromatographic column 1. Compounds eluting from the column 1 pass into a catalytic reactor 14 (typically a platinum\rhodium capillary tube containing elemental carbon and maintained at 1200°C) and are decomposed to produce carbon monoxide, molecular nitrogen, and molecular hydrogen. These gases are analyzed by an isotope-ratio mass spectrometer 4 so that the isotopic composition of the oxygen, nitrogen and hydrogen comprised in the original compound can be determined. A second chromatographic column 24 may be provided to separate carbon monoxide and nitrogen before they are passed into the spectrometer 4, thereby allowing a low resolution spectrometer to be used for the analysis of both gases at m/e 28 daltons. When only nitrogen is to be determined, the second chromatographic column 24 may be replaced by a methanizer. 
An alternative embodiment for determination of carbon isotopic composition uses a reactor 14 containing an oxygenated compound, e.g. water.

Abstract: Process for the treatment of rare-earth ores and, more particularly, ores with low contents of rare-earth elements. 
<??>The process of the invention, which permits the recovery of the said rare earths, is characterised in that it consists:
 - in performing the leaching of the rare-earth ore with the aid of a nitric acid solution,
 - in separating off the insoluble residues if need be,
 - in separating the rare earths from the solution originating from the leaching stage,
 - in treating the solution purified with regard to rare earths with a hydroxide of a metal cation M and then separating off the said precipitate,
 - in treating the solution which has been freed from the impurities with sulfuric acid and in then separating off the said precipitate,
 - optionally, in recycling the nitric acid thus regenerated to the stage of digestion of the rare-earth ore.

Abstract: Method of making articles, in particular from ceramic, having a cavity by pressing closed covers (1). 
<??>The core (2) used for delimiting the cavity and avoiding subsequent machining is initially more voluminous than the desired cavity and has a sufficient ductility for it to be partially extruded during the pressing. This prevents the often excessive mechanical stresses which can burst the densified article when the cover (1) is removed.
