US Classification:

423069000, 423071000

Abstract:

A process for increasing the solubility of titanium in oxidized titanium compounds, titaniferous ore, ore concentrate, or mixtures thereof. The process includes adding an iron compound to the titaniferous ore or ore concentrate, mixing to form a mixture, heating under a controlled atmosphere to form an iron-titanium compound, cooling, and milling to form a powder. The solubility in concentrated hydrochloric acid of the titanium in the powder is greater than the solubility of the titanium in the titaniferous ore or ore concentrate.

Abstract:

An unmanned aerial vehicle (UAV) that provides increased operational flight endurance and efficiency. The UAV includes a power generation system, which includes an internal combustion engine and one or more batteries (batteries). The power generation system is configured to generate power for propulsion of the UAV. The internal combustion engine is configured to power a lift propeller, generating vertical lift of the UAV, and the batteries are configured to power a micro-propeller assembly, propelling the UAV in a forward direction or multiple additional directions.
