  • Thermoplastic material
    Patent number: 9095948
    Abstract: Use of a thermoplastic material for blocking an optical substrate (100) in a machining position, wherein the thermoplastic material is formulated from a composition comprising a shellac and a plasticizer where the shellac and the plasticizer are chosen so as to have the softening point of the thermoplastic material greater than or equal to 60° C. and smaller than or equal to 85° C.
    Type: Grant
    Filed: November 4, 2009
    Date of Patent: August 4, 2015
    Assignee: ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE)
    Inventors: Romain Paillet, Yohann Felten, Yannick Gordiet, Jose Alcorta, Maxime Olive
  • Expanded polystyrene solubilization method
    Patent number: 8546455
    Abstract: The invention relates to a method of solubilizing expanded polystyrene (EPS), in which the EPS is brought into contact with at least one initial solvent, enabling the transition of the EPS from an expanded solid state to the gel state. The aforementioned gel is subsequently treated with at least one complementary solvent that is different from the initial solvent, enabling the solubilization thereof such as to produce a true solution. The invention also relates to the product thus obtained and to the use of said product.

    Date of Patent: October 1, 2013
    Assignee: Eska
    Inventors: Franck Poutch, Pierre Dalet, José Alcorta
  • METHOD FOR DETACHABLE GLUING FOR POROUS MATERIALS
    Publication number: 20120135223
    Abstract: A method for detachably gluing at least one porous substrate to another material using at least one layer of a detachable adhesive comprising an ungluing admixture adapted for generating gases which, by gas expansion or gas migration towards at least one of the interfaces of the detachable adhesive layer, weakens the adhesive bond when heated by a detaching control, the aforementioned method including, before gluing, applying a metal sealing coating onto at least one of the substrates.

  • STABLE COMPOSITION FOR THE DETACHABLE ASSEMBLING OF SUBSTRATES BY GLUING
    Publication number: 20110039997
    Abstract: A composition designed for the detachable assembly of a first substrate and a second substrate by gluing, includes an adhesive polymer base and at least one active substance. The active substance is encapsulated in a wax matrix so as to prevent any reaction with the adhesive polymer material during the storage of the composition or during its implementation. A process for preparing this composition is also described.

  • Non-sintered nickel electrode
    Patent number: 6335120
    Abstract: A non-sintered nickel electrode contains a conductive support and a paste comprising an electrochemically active material containing nickel hydroxide and a binder which is a mixture of an elastomer and a crystalline polymer. The proportion of the elastomer is in the range 25% to 60% by weight of the binder and the proportion of the crystalline polymer is in the range 40% to 75% by weight of the binder.
