Patents by Inventor Jacques Thuillier

Jacques Thuillier 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).

  • Nickel- and chromium-base alloys possessing very-high resistance to carburization at very-high temperature
    Patent number: 4248629
    Abstract: The invention alloy has the following by-weight composition:______________________________________ carbon 0.05 to 0.60% nickel 20 to 55% chromium 15 to 40% silicon 0.5 to 2% manganese 0.5 to 2% nitrogen 0.03 to 0.20% niobium 0 to 2% tungsten and/or molybdenum 0 to 5% aluminium 2 to 8% copper 0 to 5% iron and usual impurities in as small quantities as the balance possible ______________________________________an increased resistance to carburization is obtained by endogenous formation of a barrier opposing the penetration of aluminium.

  • Heat resisting nickel-chromium alloy having high resistance to oxidation, carburization and creep at high temperatures
    Patent number: 4063934
    Abstract: The heat resisting alloy of the invention has a high resistance to oxidation, carburization and creep at very high temperatures; its composition is as follows (in % by weight):______________________________________ Ni 24 - 53 Cr 20 - 44 C 0.01 - 0.6 Mn 0.1 - 1.5 Si 1.3 - 3 Nb 0.5 - 3 N 0.05 - 0.2 (W + Mo) 0.2 - 5 Fe 0 - 47 Cu 0 - 5 ______________________________________The minimum copper content in case the alloy contains tungsten and less than 40% nickel is at least 0.1%; the Ni/Cr ratio is between 1.20 and 1.40.
