  • Patent number: 10471823
    Abstract: A method for forming a welding spout of a plastic tank from a multilayer parison, during blowing of the parison for manufacturing the tank. The method includes, in a blowing mold including two cavities and an insert, one of the cavities delimiting a recess for forming the welding spout, the recess having a mouth opening opposite the insert: providing a push member on the insert opposite the mouth of the recess of the cavity, capable of assuming a first position set back from the recess and a second position in which the push member occupies a portion of the mouth of the recess; positioning the push member in the first position thereof; blowing the parison to match a shape of the cavities; during creeping of the parison towards the inside of the recess, moving the push member into the second position thereof.

  • Patent number: 10105393
    Abstract: The invention relates to certain low-molecular weight sulphated polysaccharide derivatives of marine native exopolysaccharides (EPSs) excreted by mesophilic marine bacteria from a deep hydrothermal environment, wherein said derivatives can be obtained by means of a method which comprises a step of free radical depolymerization of said native EPSs followed by a step of sulphating the resulting depolymerized derivatives. The present invention further relates to the use of said low-molecular weight sulphated polysaccharide derivatives as a wound-healing agent, particularly for preparing pharmaceutical compositions suitable for treating or preventing diseases of the connective tissues and particularly skin and gum tissues. The figure demonstrates how polysaccharide derivative GY 785 DRS according to the invention can stimulate fibroblast proliferation in latticed or reconstructed connective tissues at a concentration of 10 ?g (m) g/ml.

  • Publication number: 20130108819
    Abstract: Exopolysaccharides, preferably obtained by fermenting bacteria from deep hydrothermal ecosystems, serve as agents for preventing the formation of unwanted biofilms on a surface. A method for protecting a surface by preventing the formation of the primary film leading to unwanted biofilms, includes placing the surface in contact with at least one exopolysaccharide, or grafting the exopolysaccharide onto the surface. A method for modifying the physical properties of a surface such that the adhesion of an unwanted bacterial biofilm to the surface is reduced is also described.
