  • Patent number: 10100859
    Abstract: An assembly (110) comprising a core (113) and at least a first sheet (111) held on one side of the core by a rivet (120), the rivet having two ends (121, 122). At least a first one of these ends (121, 122) is flared in shape and extends at least through the entire thickness of the first sheet (111, 112). A method of fabricating such an assembly, in which: a core (113) and a first sheet (111) are provided; the first sheet (111) is placed on one side of the core (113); and the core (113) and the first sheet (111) are riveted together.

  • Patent number: 4954620
    Abstract: This material which has a hemi-cellulose content of less than 2%, a benzopyrene content of less than 2 .mu.g/kg and a calorific value which is about 20% greater than that of the starting material is obtained by isothermal treatment between 220.degree. C. and 280.degree. C. for a period of thirty minutes using crossed flows of treated material and of oxygen-free hot gases in an oven including stirring means (6,9) and a gas generator (1) with the gas being circulated by a fan (3).

  • Patent number: 4946546
    Abstract: A method of adhering a metal to a surface of a substrate of silica, quartz, glass or sapphire is set forth. The surface to be metallized is first roughened by mechanical abrasion to obtain a roughness lying between 0.2 .mu.m and 0.7 .mu.m and is then subjected to a chemical treatment of etching by immersion in an aqueous solution of HF. According to the invention, the method further comprises the following steps of ion etching of the surface down to a depth less than 30 nm and then applying to the surface a first metallic adherence layer by cathode sputtering.
