Abstract: A method for making a quality determination in avian eggs, such as relating to fertility or hatching or hatchling viability, comprises the following activities. A process line is equipped to process an endless succession of eggs at an early opportunity. The process line has an ultrasound inspection station for the eggs. The ultrasound inspection results are analyzed to make a finding correlatable to the egg's shell quality, which in turn is correlatable to such quality factors as fertility or hatching or hatchling viability. A sorting determination is made based on this analysis as to which output category the egg should be sorted. The output categories might number three or so including qualified premium as for graduation to hatchery operation, not qualified for hatchery but not waste, and flunked because unusable and hence waste. The intermediate category might include graded for pet consumption.

Abstract: A process and a device for eliminating harmful volatile elements, in particular chlorides and/or sulfates, contained in a stream of particle-laden fumes, in which a given fraction of at least 5% of the fumes, referred to as ‘by-passed fumes’, is extracted. The harmful elements of the by-passed fumes are caused to condense, at least with regard to their particles, according to a distribution that is a function of the fraction extracted, and the particles are filtered to isolate the harmful elements. At the time of filtering, the particles are separated into at least two fractions, one with a fine grain size and the other with a coarse grain size, using a separation selectivity adapted to the distribution of the elements in order for the coarse grain size faction to be poor in harmful elements and for the fine grain size fraction to be rich in harmful elements. Application to the production of cement clinker, in particular Portland cement clinker.
