Abstract
Improvements in the object of the patent 365,555 by method and apparatus for recycling and regeneration of fixing baths, and more particularly, automatic recycling and regeneration procedure of the fixing baths of the automatic development machines of sensitive surfaces, such as in particular the clichºs made in medical and industrial radiography and in the graphic arts, according to the main patent, characterized in that the fixative used is electrolyzed in the regeneration cell with a very low cathodic current density, comprised between 20 and 100 ma/dm2, before being completely or partially recycled in the fixing tank of the machine, and because the non-recycled regenerated fixer subjected in isolation, before being sent to the drainage, to a complementary electrolysis with a current density comprised between 20 and 100 ma/dm2, so that all the residual silver it contains is recovered on the cathodes.
