1940s Inventions and Technology
Transcript of 1940s Inventions and Technology
In World War II the American forces needed a tape that would be waterproof, that could be easily ripped off that can repair jeeps, aircraft, and other military supplies. The Johnson and Johnson Company's Permacel division had contributed to providing adhesive tape to the military. Later at Duct tape was used to distribute warmness and coolness in new homes at the duct work. Duct tape color and designs have developed a lot, and there are many interesting uses for it today.

Masuma Rahman Inventions and Technology of the 1940s Tupperware Earl Tupper was a Du Pont chemist that found the Polyethylene plastic made in 1942, very "pliable, attractive, and very long-lasting synthetic polymer". He started by making bathroom drinking glasses in rainbow colors and continued to the lidded bowls. In the late 1940s, Thomas Damigella and Brownie Wise sold Tupperware, enough to attract his attention. They met up and discussed ways to improve their popularity. They developed the home party plan that showed the lidded bowls in demonstration. The parties were very successful and By 1958, Tupper was able to sell his company for approximately sixteen million dollars and retire for life.

In 1948, a Los Angeles building inspector named Walter Frederick Morrison invented a plastic version of the Frisbee that could fly further and with better accuracy than a tin pie plate. In 1948, Morrison started production on plastic discs that he renamed “Flying Saucers” to cash in on the ever-growing interest and reports of UFOs. Computers Computer Frisbee Modern Frisbee The Atanasoff–Berry Computer (ABC) is considered the world's first electronic digital computer and first machine to use vacuum tubes. It was built by John Atanasoff and Clifford Berry at Iowa State University and it was successfully tested in 1942. The builders designed the ABC special-purpose computer to solve linear equations. A slinky is a coiled spring that stretches and can bounce up and down. The slinky was invented and developed by engineer Richard James in the early 1940s. It was displayed at Gimbels Department Store in Philadelphia, Pennsylvania. At first slinky were $1 but many payed more due to the price increases of spring steel all through the state of Pennsylvania. People use slinky for other uses like to simulate the properties of waves.
