Franz von Uchatius (1811–1881) was an Austrian artillery general and inventor. His inventions included both military applications and pioneer work in cinematography.
He invented a motion picture projector in 1853, developing it over the years from 1845 from the device then called
stroboscope (

SMS ''Vulcano''. The Austrians used smaller pilot balloons to determine the correct fuse settings. At least one bomb fell in the city; however, due to the wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship ''Vulcano''.

The method of strengthening bronze guns by mandrelling, or cold working them from inside with plugs of hardened steel (now known as autofrettage) was invented and patented in 1869 by Samuel B. Dean of the South Boston Iron Company

, but it found no use on the American continent. At the time most European countries were adopting steel guns, and Austrian artillery officers also vouched for adopting foreign Krupp guns in 1873, however Austro-Hungary had no steel industry at the time, so Uchatius copied Dean's technology without a license Around 1874, and his superiors decided to adopt the inferior mandrelled bronze artillery, which Uchatius marketed as "steel bronze", in order not to depend on foreign steel. They directed large investments into the state arsenal directed by Uchatius to start the production, but the result turned out to be an utter failure: more expensive, heavier and less durable than steel. Despite state propaganda trumping the success of the "indigenous" technology, the empire still had to buy heavy artillery from Krupp, and the humiliated general committed suicide in 1881; however the country stuck to the technology until the WWI, and therefore, Austrian artillery was inferior even as late as that. As a side note, Spain also adopted "steel bronze" for the same reasons alongside the Krupp guns, but withdrew them after the introduction of the smokeless powder.
