Elise Harmon
Elise (aka E'Lise) Frances Harmon (3 September 1909 – 6 March 1985 in Santa Clara County, California) was an American chemist and biologist by education and engineer by practice who invented several technologies in the emerging printed circuit board industry in the 1950s that allowed efficient printing of circuit elements on plastic substrate and continued making significant engineering innovations in circuit miniaturization into the 1970s. She also conducted critical research on the performance of electrical equipment in aircraft under extreme conditions that enhanced aircraft performance in World War II. Early life and education Harmon graduated from Marshall High School in Marshall, Texas in 1927. She earned a Bachelor of Science in chemistry in 1931 from North Texas State College (now University of North Texas) in Denton TX, a Master of Science in biology from the University of Texas in 1938, and took advanced coursework at several institutions. Harmon did post-gradua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Enterprise, Texas
Mount Enterprise is a city in Rusk County, Texas, United States. The population was 505 at the 2020 census. History The city of Mount Enterprise, located south of Henderson in rural Rusk County, was named for a small elevation near the town and for the business enterprise of the Vinzent brothers, who settled it in 1832. The town owes its existence to the presence of promising iron ore in the area. Charles Vinzent considered the "old mountain" nearby to be an "iron mountain," and he was not far off the mark; the brown, crumbly ore of the Weches formation that outcrops in the area has a better than 50 percent iron content. However, Vinzent's real enterprise came in the form of manufacturing and retailing. His factory made wagons, buggies, furniture, plows, caskets, and a patented churn. He launched a chain of stores to sell these products, and more, operating out of Mount Enterprise. At one time Vinzent had as many as four stores. Lumbering was also an early industry of Mount En ...

Thermoplastic
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. In this state, thermoplastics may be reshaped, and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendering, and extrusion. Thermoplastics differ from thermosetting polymers (or "thermosets"), which form irreversible chemical bonds during the curing process. Thermosets do not melt when heated, but typically decompose and do not reform upon cooling. Above its glass transition temperature and below its melting point, the physical properties of a thermoplastic change drastically without an associated phase change. Some thermoplastics do not fully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autonetics
Autonetics was a division of North American Aviation that produced various avionics but is best known for their inertial navigation systems used in submarines and intercontinental ballistic missiles. Its 188-acre facility in Anaheim, California, with 36,000 employees, was the city's largest employer. Through a series of mergers, Autonetics is now part of Boeing. Origin Autonetics originated in North American Aviation's Technical Research Laboratory, a small unit in the Los Angeles Division's engineering department, in 1945. In 1946, the laboratory won an Army Air Forces contract to develop a 175 to 500 mile range glide missile. The work and the lab expanded, and by June 1948, all of the Aerophysics Laboratory was consolidated at Downey, California. The evolution of the Navaho missile program then resulted in the establishment of Autonetics as a separate division of North American Aviation in 1955, first located in Downey, moving to Anaheim, California in 1963.

North American Aviation
North American Aviation (NAA) was a major American aerospace manufacturer that designed and built several notable aircraft and spacecraft. Its products included the T-6 Texan trainer, the P-51 Mustang fighter, the B-25 Mitchell bomber, the F-86 Sabre jet fighter, the X-15 rocket plane, the XB-70 bomber, the B-1 Lancer, the Apollo command and service module, the second stage of the Saturn V rocket, and the Space Shuttle orbiter. Through a series of mergers and sales, North American Aviation became part of North American Rockwell, which later became Rockwell International, and is now part of Boeing. History Early years On December 6, 1928, Clement Melville Keys founded North American as a holding company that bought and sold interests in various airlines and aviation-related companies. However, the Air Mail Act of 1934 forced the breakup of such holding companies. North American became a manufacturing company, run by James H. "Dutch" Kindelberger, who had been recr ...

LGM-30 Minuteman
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. , the LGM-30G (Version 3) is the only land-based ICBM in service in the United States and represents the land leg of the U.S. nuclear triad, along with the Trident II submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers. Development of the Minuteman began in the mid-1950s when basic research indicated that a solid-fuel rocket motor could stand ready to launch for long periods of time, in contrast to liquid-fueled rockets that required fueling before launch and so might be destroyed in a surprise attack. The missile was named for the colonial minutemen of the American Revolutionary War, who could be ready to fight on short notice. The Minuteman entered service in 1962 as a deterrence weapon that could hit Soviet cities with a second strike and countervalue counterattack if the U.S. wa ...

Society Of Women Engineers
The Society of Women Engineers (SWE) is an international not-for-profit educational and service organization. Founded in 1950 and headquartered in the United States, the Society of Women Engineers is a major advocate for women in engineering and technology. SWE has over 47,000 members in nearly 100 professional sections, 300 collegiate sections, and 60 global affiliate groups throughout the world. Antecedents The SWE archives contain a series of letters from the Elsie Eaves Papers (bequeathed to the Society), which document the origins of the Society in the early 20th century. In 1919, a group of women at the University of Colorado helped establish a small community of women with an engineering or science background, called the American Society of Women Engineers and Architects. While this organization was only recognized within the campus community, it set the foundation for the development of the international Society of Women Engineers. This group included Lou Alta Melton, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institute Of Radio Engineers
The Institute of Radio Engineers (IRE) was a professional organization which existed from 1912 until December 31, 1962. On January 1, 1963, it merged with the American Institute of Electrical Engineers (AIEE) to form the Institute of Electrical and Electronics Engineers (IEEE). Founding Following several attempts to form a technical organization of wireless practitioners in 1908–1912, the Institute of Radio Engineers (IRE) was finally established in 1912 in New York City. Among its founding organizations were the Society of Wireless Telegraph Engineers (SWTE) and the Wireless Institute (TWI). At the time, the dominant organization of electrical engineers was the American Institute of Electrical Engineers (AIEE). Many of the founding members of IRE considered AIEE too conservative and too focused on electric power. Moreover, the founders of the IRE sought to establish an international organization (unlike the “American” AIEE), and adopted a tradition of electing some ...
