Abstract: The present invention relates to a method for manufacturing a finished product having antibacterial activity comprising treating at least one face of a substrate comprising at least 50% by weight of cellulosic fibers with a composition containing as sole antimicrobial agent, a metal gluconate chosen in the group consisting of zinc gluconate, silver gluconate, copper gluconate or mixtures thereof. The invention relates to the use of metal gluconate salts as antimicrobial agents for the manufacture of substrates based on fibres, especially cellulosic fibres. The invention further relates to substrates based on fibres, especially cellulosic fibres, comprising said metal salts as antimicrobial agents.

Abstract: A device for hanging a curtain is provided. The device has a hook portion, a threaded rod portion extending from the hook portion and two cups screwed on the threaded rod portion. The threaded rod portion is passed through the curtain and the curtain is clamped by the two cups. The hook portion may then be supported on a suspended rail for hanging the curtain.

Abstract: According to the invention the material, in particular a textile, includes in its polymeric structure grafts forming complexes with at least one metal ion possessing recognized antiseptic activity. These grafts are formed by polymerization of unsaturated monomers with a complexing function, including the phosphate of ethylene glycol methacrylate or a polymerizable derivative of quinoline such as acryl 8-hydroxy quinoline. The process of preparation comprises a first step of grafting, for example by electronic irradiation of the material and impregnation with a bath of monomer, and a second step of impregnation of the grafted material with one or serveral baths containing the metal ion(s), such as copper, zinc, tin, mercury.

Abstract: The fibrous polymeric material based on polyvinyl chloride contains at least one antiseptic mercury derivative distributed in its polymeric structure in the form of a substantially molecular and practically non-releasable dispersion.The preferred mercury derivatives have the following general formula: ##STR1## in which Y is H or HgX. If the concentration of the derivative is equal to at least 0.5% by weight, relative to the chlorofiber, the latter has a permanent antiseptic character.This material is obtained by incorporating the above-mentioned derivative into the collodion when the chlorofiber is spun.

Abstract: The novel antiseptic mercurial derivatives according to the invention have at least one benzene ring and comprise: a) at least one radical HgX in which X is selected from F,Cl,Br, I, OH, CH.sub.3 COO, CN, SCN, NO.sub.3, OB(OH).sub.2, b) and, bonded to a benzene ring, at least one group--OR or--COOR in which R is a functional group capable of intervening in a reaction of polymerization or of polyaddition. The preferred derivative is 2-chloromercuri 4-tertiobutyl phenol allyl-ether. They may intervene in grafting reactions for the protection of a polymeric support, or in reactions of copolymerization.

Abstract: New mercurobutol derivatives characterized in that they comprise at least one functional group, bonded to the mercurobutol phenol ring, which functional group being capable of intervening in a polymerization or polyaddition reaction, and said derivatives having the bioactive properties of mercurobutol, even after such reaction.These new derivatives can intervene in a grafting operation either as termination agent or a polymerization agent.These new derivatives, when grafted on a support, give it protection against bacteria, mushrooms and other micro-organisms.

Abstract: Irradiated nuclear fuels consisting primarily of plutonium compounds and/or uranium compounds such as oxides, carbides, nitrides are converted in accordance with the method to plutonium hexafluoride and/or uranium hexafluoride. In a first step, the compounds are contacted within a first zone of an enclosure with a gas mixture containing at least one fluorination reagent. In a second step, the remainder of the compounds which have not been converted to fluorides during the first step is contacted directly within a second zone of the enclosure with a bed which has been fluidized by means of a gas mixture containing at least one fluorination reagent.
