  • Patent number: 4579595
    Abstract: A moist ligno-cellulosic mass was impregnated under cooling with HCl gas then it was warmed up in order to cause said mass to hydrolyze and the excess of acid to escape, the brewing action consecutive to said desorption improving the efficiency of said hydrolysis.
    Type: Grant
    Filed: May 16, 1985
    Date of Patent: April 1, 1986
    Assignee: Battelle Memorial Institute
    Inventors: Jean-Pierre Sachetto, Jean-Michel Armet, Ake A. Johansson, Alain Roman, Sergio Cuccolo
  • Patent number: 4357467
    Abstract: Depolymerized cellulose powder having substantially an amorphous structure which is obtained by letting cellulose fibers dissolve in concentrated hydrochloric acid of about 40% and at a temperature of at least 38.degree. C. A homogeneous acid hydrolysis is carried out under well controlled conditions in order to depolymerize the dissolved cellulose and is stopped when the cellulose has achieved a mean degree of polymerization between 10 and 200. The depolymerized dissolved cellulose is then separated and processed in order to obtain the aforesaid powder of amorphous depolymerized cellulose.

  • Patent number: 4297137
    Abstract: The invention relates to anti-fouling paints and is concerned with anti-fouling paints developed for inhibiting the fixation of marine organisms on structures which are immersed in sea water, the paints including at least one toxic substance uniformly incorporated into a discontinuous solid matrix which is insoluble in sea water and is dispersed in the paint, the matrix being at least partially formed from at least one substance which becomes soluble in sea water under the action of enzymes liberated by the marine organisms to be inhibited and/or by the bacterial film in contact with the surface of the paint.The paints according to the invention provide an effective life which is much longer than that of the known anti-fouling paints.The invention relates to an anti-fouling paint containing at least one toxic substance.

    Assignee: Centre National pour l'Exploitation des Oceans
    Inventors: Jean-Pierre Sachetto, Sergio Cuccolo
  • Patent number: 4267314
    Abstract: A process for the preparation of lactosylurea and the N-methylol derivative thereof which are usable as feed supplements for ruminants.According to this process, lactose and urea are heated to 70.degree.-110.degree. C. with a minimum of water and, if possible, this water is eliminated during the reaction. The crude reaction product can be purified by grinding with ice-water or ethanol and subsequent draining so as to eliminate by dissolution in such solvants the unreacted urea.The corresponding N-methylol derivative is obtained by the reaction with formaldehyde.

  • Patent number: 4110112
    Abstract: A photosensitive material is provided in which at least one surface portion of a substrate contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose uniformly distributed therethrough. A photosensitive sheet material can be formed totally of 2,3-di-(2,3-diiodopropoxy)-propyl cellulose or in part thereof, provided that the surface thereof contains 2,3-di-(2,3-diiodopropoxy)-propyl cellulose. Upon exposure to an activating electromagnetic radiation in which the intensity is modulated according to the configuration of an image, a visible image is formed on the surface of the material. Provision is further made for bringing the surface of the material into contact with the substance which forms a colored compound upon reaction with iodine liberated upon subjecting the surface to activating electromagnetic radiation.

  • Patent number: 4078140
    Abstract: The invention relates to a new substance, namely 2,3-di-(2,3-diiodopropoxy)-propyl cellulose and to the production of the same by the action of a dihalogenopropyl ether of cellulose with an alkali metal allylate with iodine addition to the resulting 2,3-di-allyloxy propyl cellulose.
