The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. Following Sturgeon's work, a commutator-type direct-current electric motor made with the intention of commercial use was built by the American inventor Thomas Davenport, which he patented in 1837. The motors ran at up to 600 revolutions per minute, and powered machine tools and a printing press. Due to the high cost of primary battery power, the motors were commercially unsuccessful and Davenport went bankrupt. Several inventors followed Sturgeon in the development of DC motors but all encountered the same battery power cost issues. No electricity distribution had been developed at the time. Like Sturgeon's motor, there was no practical commercial market for these motors.
Which inventor went bankrupt?
A: Thomas Davenport

The Federal Supreme Court has established that treaties are subject to constitutional review and enjoy the same hierarchical position as ordinary legislation (leis ordinarias, or "ordinary laws", in Portuguese). A more recent ruling by the Supreme Court in 2008 has altered that scheme somewhat, by stating that treaties containing human rights provisions enjoy a status above that of ordinary legislation, though they remain beneath the constitution itself. Additionally, as per the 45th amendment to the constitution, human rights treaties which are approved by Congress by means of a special procedure enjoy the same hierarchical position as a constitutional amendment. The hierarchical position of treaties in relation to domestic legislation is of relevance to the discussion on whether (and how) the latter can abrogate the former and vice versa.
The Brazilian Federal Supreme Court has ruled that treaties enjoy what position relative to ordinary legislation?
A: same hierarchical position
