Method and installation enabling, on the one hand, theknowledge in advance at a given moment of the result towhich a given developing chemical medium necessarily leadsand, on the other hand, the regulation of this medium toarrive at a particular result fixed in advance, to beensured.ABSTRACTInstallation enabling the checking of a developingchemical medium and its regulation, to arrive at an opti-mal value of a predetermined function of physical orchemical parameters representative of the medium, thefunction Y being connected with the values of the para-meters by a relationship of the form :Y = b0 + b1X1 + b2X2 ... + bkXk +...+ bnXn + b12X1X2 +...+ bk-1,kXk-1Xk +...+ bkkXk2 +...+ bnnXn2 +...said installation comprising: detectors intended to pro-vide the instantaneous value of each of said paramaters, ascanning member enabling the value of all of the parame-ters to be read periodically, a computer member enablingthe determination of the modification to be applied tosaid parameters to give an optimal value to the functionY, and regulating means for said parameters actuated bysaid computer member to bring the value of said parametersto the optimum.Figure 5
