Carburetor
The first carburetor was invented by Samuel Morey in 1826. The first person to patent a carburetor for use in a petroleum engine was Siegfried Marcus with his 6 July 1872 patent for a device which mixes fuel with air.
Harquebusier
According to John Cruso in his cavalry manual of 1632, the harquebusier was "first invented in France". This type of cavalryman was characterised by the use of a form of carbine, the earliest type of carbine used was called a ""harquebus"" (a word derived from the heavier infantry weapon, the arquebus). In the late 16th century and into the first decades of the following century the harquebusier was envisioned, like the similar and earlier "petronel," as a support for more heavily armoured cavalry, demi-lancers or pistol-armed cuirassiers and reiters.
