A jerrycan or jerrican (also styled jerry can or jerri can) [ 1] is a fuel container made from pressed steel (and more recently, high density polyethylene ). It was designed in Germany in the 1930s for military use to hold 20 litres (4.4 imp gal; 5.3 US gal) of fuel, and saw widespread use by both Germany and the Allies during the Second World ...
By using vacuum impregnation on uncured epoxy, winding-to-winding, winding-to-core, and winding-to-insulator air voids are eliminated. The cured epoxy is an electrical insulator and a much better conductor of heat than air. Transformer and inductor hot spots are greatly reduced, giving the component a stable and longer life than unpotted product.

The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Crude oil production. Natural oil seeps such as this in the McKittrick area of California were used by the Native Americans and later mined by settlers. The history of the petroleum industry in the United States goes back to the early 19th century, although the indigenous peoples, like many ancient societies, have used petroleum seeps since ...
