Abstract: Concentrate for activating and refining bath employed in processes of zinc phosphatization, characterized by the fact that it is based on an aqueous dispersion containing from 2 to 20% by weight of Jernstedt salts, the concentration of titanium in the dispersion consequently being from 140 to 10,000 ppm of Ti, this dispersion in addition containing:a proportion of from 0.2 to 8% by weight of at least one dispersing or sequestering agent anda proportion of from 0.05 to 7% by weight of at least one thickener based on polysaccharide.

Abstract: Composition adapted to improve the rheological properties of cement-based products and more especially to increase the duration of the workability of concrete ready to use, characterized in that it comprises, in the form of a ternary mixturea superplasticizing or water-reducing agent having a dispersing effect,a stabilizing agent capable of forming a chelate with the calcium ions of the cement-based product, anda polycarboxylic polymer dispersing agent.

Abstract: Process for the treatment of aluminum based substrates for the purpose of their anodic oxidation, comprising a surface treatment or chemical etching step using an acid bath comprising at least one fluorinated derivative of titanium and/or of zirconium and/or of silicium as well as at least one acid of the group comprising NO.sub.3 H, SO.sub.4 H.sub.2 and phosphoric acid.

Abstract: Phytopharmaceutical wettable powder comprising at least one phytopharmaceutical active substance which is solid at ambient temperature and at least one pulverulent inert filler, characterized by the fact that the constitutive particles of the filler constitute a support or carrier for the active substance comprised within a liquid composition, said active substance being selected from the group comprising:the esters of the family of the parahydroxybenzonitriles of the group comprising bromoxynil octanoate, bromoxynil heptanoate, bromoxynil butyrate, ioxynil octanoate, ioxynil heptanoate, ioxynil butyrate,the triazines of the group comprising simazine, atrazine and ametryne,the dinitroanilines of the group comprising butraline, pendimethaline, trifluraline, orizaline,the substituted ureas of the group comprising diuron, isoproturon, ethidimuron,the sulphonylureas of the group comprising especially chlorsulfuron.

Abstract: Anti-clumping product for salts, simple and complex fertilizers as well as for nitrogenous derivatives, especially on the basis of ammonium nitrate, which might in particular be used in connection with explosives, consisting of a metallic salt of an acid phosphate ester having the general formulas I and II: ##STR1## wherein: R.sub.1 designates an alkylene group having from 2 to 4 carbon atoms,R.sub.1, R.sub.2 and R.sub.3 designate each an alkyl group having from 2 to 24 carbon atoms, or an alkylaryl group whose alkyl part has from 1 to 18 carbon atoms, andn.sub.1, n.sub.2 and n.sub.3 designate an integer from 0 to 15,the cation which is part of the constitution of the above-said metallic salt being a divalent or trivalent cation, especially one of those of the group comprising magnesium, calcium, aluminum, zinc and manganese, it being also possible to select the said cation from the group consisting of sodium and lithium.

Abstract: Process for denaturating water-dilutable paints and solvent-based paints, wherein said paints are treated by washing with the assistance of an aqueous denaturation phase whose pH is from 4.5 to 7 and preferably from 5 to 6 and which contains an effective quantity of at least one denaturation agent consisting of an amine molecule of formula ##STR1## or of formula: ##STR2## in which the substituents R.sub.1 to R.sub.7, which may be identical or different, represent:a hydrogen atom,a radical of formula --O--Re in which Re is chosen from the group comprising hydrogen and a C.sub.1 to C.sub.4 saturated aliphatic hydrocarbon chain, it being understood that the substituents R.sub.5 to R.sub.7 are not simultaneously all hydrogen atoms,or of a hydrate or else of a salt of an organic or inorganic acid salt of said amine molecule, preferably a salt of sulfuric acid, phosphoric acid or hydrochloric acid.
