Guillaume Coppens has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Food compositions for pigs and processes for the feeding of pigs
    Patent number: 4563355
    Abstract: The food compositions for pigs contain calcium peroxide. Calcium peroxide is administered to the pigs via the oral route in a proportion of 0.02 to 1.3 % by weight of the total food ration.The percentage of lean meat and the quality of the carcasses are thus substantially improved.
    Type: Grant
    Filed: June 23, 1982
    Date of Patent: January 7, 1986
    Assignee: INTEROX (Societe Anonyme)
    Inventors: Ignace Gago, Guillaume Coppens
  • Process for removing residual vinyl chlorine from the polymer
    Patent number: 4424340
    Abstract: Vinyl chloride and any other comonomers present in a vinyl chloride polymer are removed by heating the polymer to a temperature between its glass transition temperature and 180.degree. C. by directly condensing steam on to the polymer, maintaining the polymer at this temperature sufficiently long to remove the greater part of the monomer or monomers present in the polymer and then cooling the polymer to below its glass transition temperature by evaporating the steam that has condensed on the polymer.
    Type: Grant
    Filed: August 27, 1982
    Date of Patent: January 3, 1984
    Assignee: Solvay & Cie
    Inventors: Jean Golstein, Guillaume Coppens, Jean-Claude Davoine
  • Compositions for ingestion by ruminants to remove protozoa, process for their preparation and use of these compositions for the feeding of ruminants
    Patent number: 4346081
    Abstract: A composition for ingestion by ruminants to remove protozoa contains a peroxide of a metal of group 2 of the Periodic Table.
    Type: Grant
    Filed: January 9, 1981
    Date of Patent: August 24, 1982
    Assignee: Interox (Societe Anonyme)
    Inventors: Ignace Gago, Guillaume Coppens
  • Process for the preparation of coated seeds
    Patent number: 4344979
    Abstract: A process for the preparation of coated seeds, in which the seeds are initially treated with an aqueous phase. The treated seeds are then coated with a coating agent containing a peroxide compound and a hydrophilic polymer, and the coated seeds are dried.
    Type: Grant
    Filed: April 1, 1980
    Date of Patent: August 17, 1982
    Assignee: Interox (Societe Anonyme)
    Inventors: Ignace Gago, Guillaume Coppens
  • Process for the manufacture of aldonic acids by an enzymatic method
    Patent number: 4345031
    Abstract: A process for the preparation of an aldonic acid from the corresponding ose, comprising enzymatically oxidizing the ose in a reaction mixture containing oxygen. The molar ratio of oxygen to ose in the reaction mixture is greater than 0.1.
    Type: Grant
    Filed: January 15, 1980
    Date of Patent: August 17, 1982
    Assignee: Solvay & Cie.
    Inventor: Guillaume Coppens
  • Process for removing residual vinyl chloride from vinyl chloride polymers in aqueous dispersion
    Patent number: 4197399
    Abstract: Process for removing the residual vinyl chloride monomer present after polymerisation in vinyl chloride polymers in the form of an aqueous dispersion which is heated to a temperature at least equal to the glass transition temperature of the polymer and subjected to stripping by an inert fluid while being maintained at a temperature at least equal to the glass transition temperature of the polymer.
