  • Patent number: 4537668
    Abstract: Cation exchanger diaphragm which can in particular be used as a solid electrolyte.This diaphragm comprises a grafted copolymer film, particularly polyethylene grafted by styrene and has an exchange capacity exceeding 0.5 meq/g, a resistivity below 100.OMEGA..cm, a swelling in water exceeding 30% compared with the dry mass and a permeability relative to oxygen and hydrogen such that in the electrolysis of water these two gases are obtained with a purity level exceeding 98%.
    Type: Grant
    Filed: June 10, 1981
    Date of Patent: August 27, 1985
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Gilbert Gaussens, Francis Lemaire
  • Patent number: 4415603
    Abstract: Process for painting a substrate, wherein the coating of a paint containing a polymerizable binder to which a peroxide is added at the time of application is applied to the substrate and wherein the thus applied coating of paint then undergoes irradiation by means of ultraviolet rays. A particular application of the invention is to the marking of road surfaces.

    Inventors: Catherine Valiot, Francis Lemaire, Gilbert Gaussens
  • Patent number: 4258156
    Abstract: The method of fabrication of a laminate formed by at least two transparent sheets consists in forming a stack of sheets after coating the sheet interfaces with a polymerizable adhesive, in subjecting the stack to an overpressure below or equal to 2 bar, in maintaining at the same time a temperature T below the maximum temperature of stability of the adhesive for a sufficient period of time to obtain prepolymerization of the adhesive, then in maintaining the stack temperature below or equal to the temperature T for a period of less than sixteen hours.
    Type: Grant

    Inventors: Jacques Guerrini, Jeanne Berthet, Gilbert Gaussens, Francis Lemaire
  • Patent number: 4253142
    Abstract: A microinstruction address is determined in response to the content of an mediately preceding microinstruction. A data processing apparatus contains a memory for storing microinstructions at addressable locations. Testing bits are loaded into a test register while a microinstruction read from the memory is loaded into a microinstruction register.

    Assignee: Compagnie Internationale pour l'Informatique-CII Honeywell Bull
    Inventors: Robert Bavoux, Francis Lemaire, Pierre Salkazanov
  • Patent number: 4230766
    Abstract: The fibers constituting the composite material are impregnated with a composition containing at least one unsaturated epoxy resin mixed with at least two ethylenic monounsaturation monomers, at least one ethylenic polyunsaturation monomer, a photoinitiator and an organic peroxide. The composition is prepolymerized by means of ultraviolet rays in a first step and then cross-linked either by ultraviolet rays or a temperature rise in a second step.

    Inventors: Gilbert Gaussens, Francis Lemaire, Bach Van Nguyen
  • Patent number: 4223392
    Abstract: A plurality of sub-clock signals are derived from a main clock signal sou by advancing a shift register and a counter with pulses from the main clock source. The shift register is selectively loaded with a desired combination of sub-clock bits in response to a predetermined number of main clock pulses being supplied to the counter. The sub-clock signals are derived from output terminals at different stages of the shift register. The state of the sub-clock signals can be selectively frozen by decoupling pulses from the main clock source to inputs of the counter and shift register.

    Assignee: Compagnie Internationale pour l'Informatique Cii-Honeywell Bull
    Inventors: Francis Lemaire, Pierre Salkazanov, Robert Bavoux
  • Patent number: 4196065
    Abstract: A method for the volumetric inclusion and grafting of hydrophilic compounds in a hydrophobic substrate, comprising the steps of immersing said hydrophobic polymerized substrate in a solution containing hydrophilic monomers in the presence of at least one polymerization inhibitor, and irradiating said solution by means of an ionizing radiation, in order to graft and polymerize the hydrophilic inclusions generated by the hydrophilic monomers in said substrate.

    Date of Patent: April 1, 1980
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Gilbert Gaussens, Francis Lemaire
  • Patent number: 4001462
    Abstract: A coating compound which is hardenable under the action of ionizing radiations contains an epoxy resin which is modified by unsaturated carboxylic acids as a result of reaction of the COOH groups of the acids with the epoxy bridges of the resin and as a result of esterification of the hydroxyl groups of the resin.
