Latest Patents
Jacques L Alexandre holds a patent for a method and installation for the analysis by neutron activation of a flow. This method allows for the analysis of the content of certain elements in a continuous flow of bulk materials by neutron bombardment. It measures the gamma radiation emitted by these elements, enabling the distinction between capture radiation and activation radiation. The neutron source utilized is a neutron-generating tube that is activated periodically. The signals from a single gamma radiation detector are considered only after neutron emission has ceased, during distinct intervals corresponding to the phenomena of capture and radiation of the activated elements. The respective signals are treated in two distinct measurement routes, and the measurements are then combined automatically. Additionally, a third measurement route can be provided for gamma radiation resulting from inelastic collisions. The source and the detector are positioned in a probe lodged in a polyethylene protective tube within the flow of the materials. This installation is particularly useful for analyzing large flows of minerals without the need for sampling, making it applicable in the mining, cement, and aluminum industries.
