History lesson 70

The first invention I learned about this week was the safety elevator. Elisha Otis invented the safety elevator in 1852. Otis was looking for a better, safer way to lift scrap wood in a factory. The safety mechanism stops the elevators from plummeting to the ground if the cables snaps. Otis implemented a dramatic marketing demonstration of his elevators to attract interest and promote sales. Otis elevators are installed all of the world in many skyscrapers.

The second invention I learned about this week was the syringe. Inspired by a bee’s stinger, Scottish doctor Alexender wood invented the syringe in 1853 for injecting morphine. The syringe allows control and measurement of how much medicine is ejected out of the syringe. For the next 100 years, syringe design was innovated. The syringe has made surgery much safer and medicine much more effective.

The third invention I learned about this week was the Bessemer process. Henery Bessemer invented his steel-making process in 1855 after a discussion with napoleon the third about better weapons for the war. The process efficiently converts large batches of pig iron into steel, reducing its price and increasing its production rate. It was licensed in America in 1865. Steel resulted in transformation of civilization in Structural ways.

The fourth invention I learned about this week was the eggbeater. Baking had been controlled by guilds for much of history, but the eggbeater was a simple invention in 1856. The modern eggbeater is a kitchen mixer that automates the stirring and mixing of Ingredientes. The result of the eggbeater was the creation of frozen baked goods industry.

The most interesting thing I learned about this week was how you can make small scale models that work the same as something as big as a building. I found this interesting because the model can be as big as your hand but still have all the parts to work like a normal size machine. Thats what I found interesting this week.
