A guy wakes up with a massive hangover and stumbles into the kitchen, where he finds his wife.
“Hey, honey, did you upgrade the bathroom?” he asks.
“Why do you ask?” she replies, curious.
“Well, I opened the bathroom door, the light turned on by itself, and a cool breeze blew right into my face! It was amazing!”
His wife glares at him and says, “So you’re the idiot who pissed in the fridge last night!”
Steel manufactureIn 1857, Robert Mushet, an English metallurgist, received a U.S. patent for a method of manufacturing steel which improved the Bessemer process for making steel that would be more malleable. (No. 17,389). His process added manganese in the form of spiegeleisen, an alloy of iron and manganese derived from a Prussian iron ore consisting essentially of a double carbonate of iron and manganese. The softness or hardness of the steel could be regulated by diminishing or increasing the proportion of the triple compound of iron, carbon and manganese. He chose to use the alloy of the Prussian ore because it was more free of sulphur, phosphorus and silicon. Mushet also discovered tungsten steel, an alloy with about 8% tungsten. |
