Patents by Inventor Jean Gombert

Jean Gombert 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).

  • Method for the impervious metallic coating of an optic fiber and device
    Patent number: 4853258
    Abstract: The invention pertains to a method for metallic coating according to which the fiber is made to pass through a bath of molten metal. To prevent unevennesses in coating, caused by turbulence, a depression is made above the bath.The invention also pertains to a device by which the method is applied. The fiber goes vertically through a pot containing the molten metal above which the depression is made.The invention can be used to make optic fibers of greater mechanical strength.

  • Method of manufacturing an optical fiber with chiralic structure and a device for putting this method into practice
    Patent number: 4572840
    Abstract: The method consists in twisting a fiber already coated with a primary coating about its axis of symmetry at a temperature less than the vitreous transition temperature of this fiber; in coating it with a polymer in the viscous state so as to form an envelope about this fiber; in curing said polymer while increasing its YOUNG's modulus.

  • Process for producing doped vitreous silica for preparing a preform for an optical fibre
    Patent number: 4493720
    Abstract: The invention relates to a process for producing ultrapure doped vitreous silica for producing a preform for optical fibres. According to the invention, an ultrapure porous glass, glass obtained after its shaping, is used as the crude starting material in a deposition process of the plasma torch, grain by grain Verneuil type, for example, in order to complete a preform obtained by said process for the separation of phases and acid washing or etching of the glasses.
