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.
James Trane
In 1925, Reuben Trane invented a new type of heat transfer device known as the convector radiator. It consisted of a new style of heat exchanger in a sheet metal cabinet—a highly efficient, lightweight replacement for the bulky, slow responding castiron radiator. In 1931, The Trane Company developed its first air conditioning unit, the Trane unit cooler, and in 1938 its first centrifugal refrigeration machine, the Turbovac.
