Year 422 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Capitolinus, Mugillanus and Merenda (or, less frequently, year 332 Ab urbe condita). The denomination 422 BC 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.

The International 420 Class Dinghy (not to be confused with the Club 420) is a double-handed (2 crew) monohull planing dinghy with centreboard, bermuda rig and center sheeting. The name describes the overall length of the boat in centimeters (the boat is exactly 4.2 meters long). The hull is fiberglass with internal buoyancy tanks. The 420 is equipped with spinnaker and optional trapeze, making teamwork necessary to sail it well. It has a large sail-area-to-weight ratio, and is designed to plane easily. It can be rigged to be sailed single-handed.The 420 was designed specifically to be easier to handle than its larger higher-performance cousin, the 470. The 420 was designed by French engineer Christian Maury, as a stepping-stone for club and youth sailing to the 470. The 420 is an International class recognized by the International Sailing Federation.A derivative of the 420 called the Club 420 is popular in the North America. This class is not recognised by International Sailing Federation or the International 420 Class Association and cannot be used at class events. The boats are very similar in appearance but the Club 420 is slightly stronger, heavier and less refined.

The Forty-first United States Congress was a meeting of the legislative branch of the United States federal government, consisting of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from March 4, 1869 to March 4, 1871, during the first two years of Ulysses Grant's presidency. The apportionment of seats in the House of Representatives was based on the Eighth Census of the United States in 1860. Both chambers had a Republican majority.

The 41st Virginia Volunteer Infantry Regiment was an infantry regiment raised in the Commonwealth of Virginia for service in the Confederate States Army during the American Civil War. It fought mostly with the Army of Northern Virginia in Longstreet's corps and, later, that army's Third Corps.The regiment was formed from independent militia companies operating in the Norfolk area, with men from the surrounding counties, as far west as Petersburg. Throughout the war it operated in brigades under William Mahone and David A. Weisiger, and the divisions of Benjamin Huger, Richard H. Anderson, and William Mahone. The regiment participated in the capture and later abandonment of Norfolk Naval Yard, and every major campaign of the Army of Northern Virginia. Several dozen men and officers of the regiment also served on the CSS Virginia in the Battle of Hampton Roads. The 41st Virginia was also involved in the friendly fire incident that severely wounded James Longstreet during the Battle of the Wilderness.

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded (need pre and post weld thermal treatment to avoid cold cracking).While these grades of steel do contain chromium, it is not in great enough quantities to provide the corrosion resistance found in stainless steel.Examples of applications for 4130, 4140 and 4145 include structural tubing, bicycle frames, tubes for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages. 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by the United States military. These steels are also used in aircraft parts and therefore 41xx grade structural tubing is sometimes referred to as "aircraft tubing".

The 420th Flight Test Flight (420 FLTF) is an inactive United States Air Force Reserve squadron. It was last assigned to the 413th Flight Test Group of Air Force Reserve Command at Phoenix-Mesa Gateway Airport, Arizona, where it was inactivated on 31 October 2007.The squadron was first activated as the 420th Night Fighter Squadron, one of the first dedicated Night Fighter Operational Training Squadron of the Air Force. It trained replacement night fighter pilots who were then deployed overseas into combat until its inactivation in March 1944 due to a re-alignment of training unit designations.It was reactivated as the 420th Air Refueling Squadron under Tactical Air Command in 1954 and moved to England, where it served under the United States Air Forces Europe. It was inactivated when Strategic Air Command assumed the role of single manager for USAF air refueling. In 1985 the night fighter and refueling squadrons were consolidated into a single unit.The 6520th Test Squadron was organized in 1989 by Air Force Systems Command. In 1992, as the USAF eliminated Major Command controlled (MAJCON) units, the 6520th was consolidated with the 420th and re-designated as the 420th Flight Test Squadron. The squadron was inactivated as an active-duty unit in 1997, but was activated four years later in the Air Force Reserve Command as the 420th Flight Test Flight.

The 41st Regiment Wisconsin Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War. It was among scores of regiments that were raised in the summer of 1864 as Hundred Days Men, an effort to augment existing manpower for an all-out push to end the war within 100 days.

420356 Praamzius is a trans-Neptunian object (TNO) and possibly a dwarf planet in the Kuiper belt. It has the second-lowest eccentricity of any TNO, after 2003 YN179. Praamzius orbits near the 3:5 resonance with Neptune, but it takes about 160 Neptune orbits (26,500 years) to make an orbit less than would be expected of an object in a true 3:5 resonance. It was discovered on 23 January 2012, with precovery observations accepted by the Minor Planet Center dating back to December 2011, with possible precovery observations dating back to 2004 that have yet to be accepted. It was officially named on 22 February 2016 after the Lithuanian god of the sky, peace, and friendship.Praamzius is one of the most recently discovered minor planets that have been given a numeric designation, most likely because of the large number of observations, on average about one every 10 days, since it was discovered. All of the observations, except 6 in February 2013, were made by the Mount Graham Observatory, the discovery site.Analysis of precovery observations of Praamzius from 2002, 2003, 2004, and 2007, show that it is probably one of the reddest objects in the solar system, being more than 1.5 magnitudes fainter measured in the G (green) filter than the R (red) filter.

The 422nd Rifle Division was formed for the first time as a standard Red Army rifle division late in 1941, after the Soviet winter counteroffensive had begun, but was soon re-designated. A second formation began in March, 1942, again in the far east of Siberia, until July, after which it was moved west to join the reserves of Stalingrad Front in August. It was the highest-numbered rifle division to see active service in the front lines during the Great Patriotic War. Over the course of the next six months, the division distinguished itself in both defensive and offensive fighting and earned its re-designation as the 81st Guards Rifle Division on the first day of March, 1943. The 422nd was never reformed.

After training, it was deployed to Fifth Air Force and ordered to New Guinea to provide air defense interceptor protection against Japanese night air raids on USAAF airfields. It later served in the Philippines Campaign where in addition to night interceptor missions it also flew day and night interdiction missions against enemy troop movements, bridges and other targets of opportunity. It later served on Okinawa and in Occupied Japan where it was inactivated in 1947.It was re-activated by Tactical Air Command in 1962 as the 421st Tactical Fighter Squadron. Equipped with F-105 Thunderchiefs, it deployed to Southeast Asia and engaged in combat operations over North Vietnam. It returned to the United States and was re-equipped with the F-4D Phantom II and returned to Southeast Asia for a second and later third tour of duty in the Vietnam War. It was one of the first USAF Squadrons equipped with the F-16A Fighting Falcon in 1980; and went on to serve in the 1991 Gulf War. In recent years, the squadron has deployed to the United States Air Forces Central Command, engaging in combat during Operation Enduring Freedom and Operation Iraqi Freedom.

In automobiles, a 42-volt electrical system was an electrical power standard proposed in the late 1990s. It was intended to allow more powerful electrically driven accessories, and lighter automobile wiring harnesses. Electric motors were proposed to be used for power steering or other systems, providing more compact installations and eliminating the weight of drive belts or large wires for high-current loads.The proposed new standard was more than triple the voltage of existing "12 volt" systems. The higher voltage was selected to provide greater power capacity for wiring and devices on one hand, and to stay under the 50 volt limit used as a guideline for electric shock hazard. The European auto manufacturer Daimler-Benz proposed a 42V brand name for the conversion.Although many manufacturers were predicting a switch to 36-volt (lithium ion battery) / 42-volt (charging voltage) electrical systems, the changeover has not occurred, and the plans appear to have been canceled. The availability of higher-efficiency motors, new wiring techniques and digital controls, and a focus on hybrid vehicle systems that use high-voltage starter/generators has largely eliminated the push for switching the main automotive voltages. Applications that once were thought to require higher voltages, such as electrical power steering, have now been achieved with 12 volt systems. 42-volt electrical components are now used in only a few automotive applications, since incandescent light bulbs work well at 12 volts and switching of a 42-volt circuit is more difficult.

4209 Briggs, provisional designation 1986 TG4, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 28 kilometers in diameter. It was discovered by American astronomer Eleanor Helin at the U.S. Palomar Observatory, California, on 4 October 1986.The dark C-type asteroid orbits the Sun at a distance of 2.9–3.4 AU once every 5 years and 7 months (2,047 days). Its orbit has an eccentricity of 0.08 and an inclination of 22° with respect to the ecliptic. The first precovery was obtained at El Leoncito in 1969, extending the asteroid's observation arc by 17 years prior to its discovery.A rotational light-curves of this asteroid was obtained from photometric observations made by American astronomer Brian Warner at the Palmer Divide Observatory in September 2003. The revised light-curve showed a rotation period of 7001122200000000000♠12.22±0.02 hours with a brightness variation of 0.45 in magnitude (U=3-). A second light-curve from a collaboration of Czech, U.S. and Italian observatories published in November 2013, rendered a period of 7001122530000000000♠12.2530±0.0005 hours (U=n/a).According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its NEOWISE mission, the asteroid measures between 25.6 and 31.3 kilometers in diameter and its surface has an albedo in the range of 0.07 to 0.13. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 25.4 kilometer, slightly below the result obtained by IRAS.The minor planet was named after American space physicist Geoffrey A. Briggs, director of the Solar System Exploration Division at NASA Headquarters during the 1980s. He was instrumental for the formation of the U.S.–Soviet Joint Working Group for Solar System Exploration and became its co-chairman. He was on the imaging teams for the Mariner, Viking and Voyager missions. Briggs continued to promote space-related accomplishments to the public at the Air and Space Museum. Naming citation was published on 27 June 1991 (M.P.C. 18456).

4222 Nancita, provisional designation 1988 EK1, is an eccentric, stony asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered by American astronomer Eleanor Helin at the U.S Palomar Observatory, California, on 13 March 1988. It will become a Mars-crossing asteroid in June 2019.The S-type asteroid orbits the Sun at a distance of 1.7–3.1 AU once every 3 years and 8 months (1,331 days). Its orbit has an eccentricity of 0.29 and an inclination of 4° with respect to the ecliptic. The first used precovery was obtained at Crimea–Nauchnij in 1968, extending the asteroid's observation arc by 20 years prior to its discovery.A photometric light-curve analysis at the Australian Hunters Hill Observatory and collaborating stations in 2006 rendered a rotation period of 3.87 hours with a high brightness amplitude of 0.97 in magnitude. According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures between 8.5 and 9.7 kilometers in diameter and its surface has an albedo in the range of 0.21 to 0.27. The Collaborative Asteroid Lightcurve Link gives preference to the results obtained by IRAS.The minor planet was named "Nancita" in honor of Nancy Coker Helin, daughter-in-law of the discoverer, and wife to Bruce Helin, after whom the minor planet 2430 Bruce Helin had previously been named. Nancy is described by the discoverer as a talented singer, composer and teacher, who has brought music and joy to her family. Naming citation was published on 2 December 1990 (M.P.C. 17466).
