Daniel L. Hertz Jr.
Daniel L. Hertz Jr. (February 27, 1930 - January 9, 2021) was an entrepreneur, executive and self-educated scientist noted for his leadership in the rubber industry. Personal Hertz was born to Daniel L. Hertz Sr. and Elizabeth Beet Hertz in Montclair, New Jersey, on February 27, 1930. He married Isabel P. Waud. He served in the Korean War in the Army. Education Hertz attended Stevens Institute of Technology, studying mechanical engineering, but he was asked to leave after his freshman year. He was later award an honorary degree, of which he said "that honorary degree came like a shot out of the blue... that kept me alive for years, it really did. After I was kicked out of Stevens, I thought if I ever showed up on campus I'd be lynched." Career He worked for a time as a salesman for Precision Rubber Products, and for a distribution company named Linear. At the age of 23, Hertz founded Seals Eastern Inc to design and manufacture o-rings. In 1986, following the Space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montclair, New Jersey
Montclair () is a township in Essex County in the U.S. state of New Jersey. Situated on the cliffs of the Watchung Mountains, Montclair is a wealthy and diverse commuter town and suburb of New York City within the New York metropolitan area. As of the 2020 U.S. census, the township's population was 40,921, reflecting an increase of 3,234 (+8.5%) from the 37,687 counted in the 2010 Census. As of 2010, it was the 60th-most-populous municipality in New Jersey. Montclair was first formed as a township on April 15, 1868, from portions of Bloomfield Township, so that a second railroad could be built to Montclair. After a referendum held on February 21, 1894, Montclair was reincorporated as a town, effective February 24, 1894.Snyder, John P''The Story of New Jersey's Civil Boundaries: 1606–1968'' Bureau of Geology and Topography; Trenton, New Jersey; 1969. p. 129.

Stevens Institute Of Technology
Stevens Institute of Technology is a private research university in Hoboken, New Jersey. Founded in 1870, it is one of the oldest technological universities in the United States and was the first college in America solely dedicated to mechanical engineering. The 55-acre campus encompasses Castle Point, the highest point in Hoboken, a campus green and 43 academic, student and administrative buildings. Established through an 1868 bequest from Edwin Augustus Stevens, enrollment at Stevens includes more than 8,000 undergraduate and graduate students representing 47 states and 60 countries throughout Asia, Europe and Latin America. Stevens comprises three schools and one college that deliver technology-based STEM (science, technology, engineering and mathematics) degrees and degrees in business, arts, humanities and social sciences: The Charles V. Schaefer, Jr., School of Engineering and Science, School of Business, School of Systems and Enterprises, and College of Arts and Letters. F ...

The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. Eastern Time Zone, EST (16:39 Coordinated Universal Time, UTC). It was the first fatal accident involving an List of space programs of the United States, American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the Space Shuttle orbiter, orbiter and the twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit, in addition to taking school teacher Christa McAuliffe into space. The latter resulted in a higher than usual media interest and coverage of the mission; the launch and subsequent disaster were seen live in many schools across the United States. The cause of the disaster was the failure of the two O-ring seals in a joint in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitrile Rubber
Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks. It is used in the nuclear industry to make protective gloves. NBR's stability at high temperatures from makes it an ideal material for aeronautical applications. Nitrile butadiene is also used to produce moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats. Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior flexibility. History Nitrile rubb ...

Polymer Scientists And Engineers
A polymer (; Greek ''wikt:poly-, poly-'', "many" + ''wikt:-mer, -mer'', "part") is a Chemical substance, substance or material consisting of very large molecules called macromolecules, composed of many Repeat unit, repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form glass, amorphous and crystallization of polymers, semicrystalline structures rather ...

1930 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
