In addition to being more durable than a leather or cloth case due to its rigidity, the aluminium case seals tightly against dust and water. Famously, the nuclear football , the briefcase which the President of the United States can use to order a nuclear strike, is a modified Zero Halliburton case, [ 1 ] although enclosed in a black leather ...
Halliburton designed the aluminum suitcases which are now manufactured by Zero Halliburton. "An Uncommon Man;" Erle P. Halliburton Monument in Memorial Park, Duncan, OK; erected – 1993. Halliburton was inducted into the Oklahoma Hall of Fame in 1957. [4] Halliburton died on October 13, 1957, in Los Angeles at the age of 65.
In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...
In 1998, Dresser merged with its main rival Halliburton. [1] Halliburton sold many of former Dresser non "oil patch" divisions, retaining the M W Kellogg Engineering and Construction Company and the Dresser oil-patch products and services that complemented Halliburton's energy and natural resource businesses. In 2001 Halliburton sold five ...
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
Gearhart Industries, The GO Company (formerly GO Oil Well Services, Gearhart-Owen Industries) was an oil well service company founded by Marvin Gearhart and Harrold Owen in 1955 and based in Fort Worth, Texas, United States.
Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some limited contact-sealing action that creates the seal.
