IPC: C22B3/10
Filed: 1999-10-20
Abstract: The invention relates to a process for treating tantalum and/or niobium containing raw materials such as wastes, slags, concentrates and ores. The tantalum and/or niobium containing raw materials are processed by repeated u se of a solution of ammonium fluoride. From the tantalum and niobium containing  aqueous solution a mixture of fluorides and oxide fluorides of tantalum and niobium are transformed into a firm condition. At an extraction stage pure, aqueous solutions containing fluoro acid complexes of niobium and fluoroammonium complexes of tantalum are obtained. From these tantalum and niobium are obtained as oxides in pure form by precipitating them as fluorid e containing oxide hydrates by addition of ammonia. The obtained oxide hydrate s are transformed into pure oxides by calcining at high temperatures.

Title: Airship/spacecraft
Inventor: PROVITOLA ANTHONY I
IPC: B64G1/40
Filed: 2000-04-11
Abstract: An airship/spacecraft, which, in a preferred embodiment, uses its lifting gas (64) as fuel for thrusters, which may be of the turbo-type or rocket type, or both, to achieve transition to space flight. The airship aspect has gas retaining structures (61) that can withstand internal and external pressure and can change in volume and shape. The gas retaining structures (61) may be compartmentalized with a folded diaphragm membrane (63) and also configured as pressure vessels. The spacecraft aspect provides control, power, services, and space for missions of the airship/spacecraft. The best mode includes a turbo-rocket thruster in which the turbine compressor is used to intake and compress a gaseous fuel for combustion with a stored oxidizer injected into the compressed gaseous fuel stream. The compressor stage (6) is driven by the turbine stage (7), which is driven by burning gaseous fuel passing across the turbine blades (13). The burned gases are then expanded through an exhaust nozzle and thereby ejected to produce reaction thrust.
