An installation for determining the content of the various constituents of a bulk material using pulsed neutron irradiation. It employs measurement apparatus 1 comprising a source of neutron irradiation and a measuring region for the gamma radiation, means 2 for providing continuous circulation of the bulk material, means for receiving the data for the resulting spectra 6 and computing means 7 enabling comparison to be made of said spectral data with data resulting from measurements carried out under identical conditions on each one of the pure constituents the presence of which is being investigated together with readout means 8 for the averaged computed result.

Why it's free to use
- Filed June 21, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
