  • Process and structure for fixation of atmospheric nitrogen
    Patent number: 4039412
    Abstract: A process and structure are described for fixing atmospheric nitrogen to oxygen to produce oxides of nitrogen. Energy required for the conversion process is drawn from radiations produced by radioactive wastes from nuclear reactors. Preferably, two complementary stages are employed in the conversion process. First, waste heat from spent fuel rods is employed as a heat source for producing nitrogen oxides. Second, radioactive waste materials chemically separated from spent reactor fuel rods are employed in a second stage as an ionization source for producing nitrogen oxides.

  • Electrically conductive object having an ablative layer thereon for protecting the same from damage by an electrical discharge
    Patent number: 3965285
    Abstract: A process and structure are described for protecting objects from the damaging effects of electrical discharges by employing a coating of a conductive, ablative material such as graphite. Upon occurrence of an intense electrical discharge to this material, it evaporates to dissipate the heat produced by the discharge and protect the structural integrity of the object.
