Origin of TXV

[addamsmasher]

Homework for class this week is to find out when and who created the first TXV and what its application was. I'm counting on you guys to come through, google, wiki, ask.com searches to no avail. Thanks

Egyptians made the first known TXV in the time of the Pharoahs. However, it was used for propane barbeques way back then. Building the pyramids came later.
