Abstract: Improved methods of synthesizing ammonia from hydrogen sulfide and lithium nitrate are disclosed. Specifically, in a continuous cycle, hydrogen sulfide reactant is regenerated from the elemental sulfur that is extracted from a product of the ammonia synthesis, and the regenerated hydrogen sulfide is fed back into the ammonia synthesis reaction. The cycle that regenerates the hydrogen sulfide uses either a water-containing or a water and carbon-containing feedstock to facilitate the regeneration of the hydrogen sulfide from the elemental sulfur.

Abstract: An inspection vehicle structured to inspect a portion of the turbine disk, preferably the blade attachment hubs, while the turbine disk is disposed within a turbine housing assembly is provided. A turbine disk is generally planar but includes a inner hub and an outer blade attachment hub. The inner hub is coupled to a shaft and the blade attachment hub provides a surface to which removable blades are attached. The area between the inner hub and outer blade attachment hub is substantially planar. The inner and blade attachment hubs are the “inspection areas” that the inspection vehicle is structured to inspect. The inspection vehicle travels over, and is magnetically coupled to the planar surface between the two hubs.
