The Weston cell is a wet-chemical cell that produces a highly stable voltage suitable as a laboratory standard for calibration of voltmeters. Invented by Edward Weston in 1893, it was adopted as the International Standard for EMF from 1911 until superseded by the Josephson voltage standard in 1990.
In 1918, Rueben Bechtold and Alfred Mellowes produced a refrigeration machine compact enough to fit under an appliance. Before that, the units were too large and so placed outside the home. Their company was unsuccessful, but was bought by General Motors and renamed Frigidaire, which improved this design to build the first household refrigerators.
