Guide rail. A guide rail is a device or mechanism to direct products, vehicles or other objects through a channel, conveyor, roadway or rail system. 

Several types of guide rails exist and may be associated with:
 Factory or production line conveyors
 Power tools, such as table saws
 Elevator or lift shafts
 Roadways and bridges (in this context sometimes called guardrails)
 A central rail that guides the rubber tired train of a rubber tired metro

Factory guide rail
Most factories use guide rails convey products and component parts along an assembly line. This conveyor system propels products  of various sizes, shapes, and dimensions through the factory over the course of their assembly.

Power tool guide rail
Accessory to a power tool, such as a straight, swivel or angle jig for a circular saw, and can also be referred to as a fence.  The guide rail system provides an acute method of cutting material.

Elevator shaft guide rail
Guide rails are part of the inner workings of most elevator and lift shafts, functioning as the vertical, internal track. The guide rails are fixed to two sides of the shaft; one guides the elevator car and the other for the counterweight. In tandem, these rails operate both as stabilization within the shaft during routine use and as a safety system in case of emergency stops.

Roadway guide rail

A guide rail is a system designed to guide vehicles back to the roadway and away from potentially hazardous situations. There is no legal distinction between a guide rail and a guard rail. According to the US Federal Highway Administration, the terms guardrail and guiderail are synonymous.

Several types of roadway guide rail exist; all are engineered to guide vehicular traffic on roads or bridges. Such systems include W-beam, box beam, cable, and concrete barrier. Each system is intended to guide vehicles back onto the road as opposed to guard them from going off the road into potential danger.

Railway guide rail

On the Sapporo Municipal Subway a central rail guides the train. The Lille Metro, Translohr and Bombardier Guided Light Transit are also guided by a central guide rail.

Latécoère 23. The Latécoère 23 was a development of the Latécoère 21 flying boat, a twin-engined parasol winged aircraft. Only one was built, flying and crashing in late 1927.  The similar Latécoère 32 was its immediate successor.

Design and development
The Latécoère 23 was a development of the Latécoère 21, the latter Latécoère's first flying boat to leave the water.  It kept the same general arrangement, a parasol winged machine with a centrally mounted push-pull pair of engines and sponsons for stability on the water.  Its wing, like that of the earlier aircraft was very rectangular and of mixed wood and metal construction.  The span was increased by 27% and the wing area by about the same.  The sharply cropped wingtips of the Latécoère 21 were replaced by bevelled ends of decreasing thickness.  The Latécoère 23 carried full span ailerons in three sections per wing, fitted with trim tabs.   The wings were not attached directly to the fuselage, but to the sponsons: on each side a parallel pair of streamlined struts leaned outwards from near the tip of the sponson to mid-wing, and a second pair ran inwards to the wing centreline below the engines.  On the Latécoère 21 the engines were mounted on the chord line, but the two 500 hp (373 kW) Farman 12 Wes of the later aircraft were mounted on the upper surface of the wing.  Propellers were four bladed and wooden.

The fuselage of the Latécoère 23 was 1.30 m (2 ft) shorter than that of its predecessor and the major hydrodynamic alteration was the inclusion of two steps rather than one.  It was built of wood.  The broad sponsons of airfoil section and almost rectangular plan were also mostly made of wood apart from four duralumin longerons. They were set at an appropriate angle of incidence to provide extra lift.  There was a mooring position in the nose, an open cockpit for pilot and mechanic.  Two internal cabins, one ahead of the cockpit and one aft could each accommodate four passengers.  The tail unit of the Latécoère 23 was much cleaner than that of its predecessor, with control surfaces merging smoothly into the lines of tailplane and fin.  The former was unbraced and mounted about halfway up the fin, with a large cut-out for rudder movement.

Achille Enderlin, Latécoère's test pilot was in charge of trials during the autumn of 1927.   These passed without incident, but on 31 December 1927, with Enderlin and four others on board spun in during landing approach, killing everyone.  No more Latécoère 23s were built, but by the time of the crash the first examples of its rather similar successor, the Latécoère 32 were in service.

IS-3 ABC. The IS-3 ABC (Instytut Szybownictwa – Gliding Institute)  was a single-seat training glider designed and built in Poland from 1947.

Development 
From 1946 the IS (Gliding Institute) started work on designing gliders to rebuild the shattered by the war Polish gliding movement. Four types were required:
1. School (IS-3 ABC)
2. Transition (IS-A Salamandra)
3. Training and intermediate performance (IS-2 Mucha)
4. High performance / advanced (IS-1 Sęp)
To fulfil the 'School' requirement the IS-3 ABC primary glider was designed by Rudolf Matz and Roman Zatwarnicki, and built at the workshops in Bielsko.

Using the sole remaining W.W.S.1 Salamandra as a starting point, the IS-3 ABC emerged looking similar to most primary gliders, with a high set rectangular low aspect ratio wing, wire-braced to an open structure wire-braced fuselage, which did nothing more than connect the seat, skid and tail unit to the wings.

The IS-3 ABC prototype first flew on New Year's Eve of 1948 by Peter Mynarski and after successful trials, a production commenced as the IS-3 ABC-bis. Further improvements resulted in the IS-3 ABC-ter, with a cabin and windscreen for the pilot. Last and most numerous variant was ABC-A of 1955, produced in 1956-57. 256 of all variants were manufactured in workshops in Bielsko (of IS, later SZD), Krosno and Lubawka (according to other publications, 280, including 74 bis, 30 ter and 176 A).

Polish instructors were also instrumental in boosting the gliding movement in the People's Republic of China, providing instruction and advice with the 50 IS-3 ABC A's exported there. This variant was modified with less dihedral (1°), to allow the generally shorter Chinese students to hold the wings level for take-off. After flight trials in Poland, it was confirmed that it did not appreciably affect the handling. The Chinese also manufactured these gliders on the licence.

The IS-3 ABC series was in use at Polish state gliding clubs up to 1961, when the dual training syllabus was finally introduced. Many of the IS-3 primary gliders were dispersed to schools and clubs for use as training aids, some of which survive as exhibits in museums today.

Variants 
 IS-3 ABC – The sole prototype aircraft without folding wings.
  IS-3 ABC bis – production aircraft with reduced wing incidence, increased aileron movement and with folding wings and tail-unit (24 made in IS and 50 in Lubawka).
 IS-3 ABC ter – version equipped with a removable cockpit nacelle and windscreen as well as fixed wings and tail-unit (30 made in Lubawka)
  IS-3 ABC-A – last production version, with less wing dihedral, produced in 1956-57 (most in Krosno).

Győző Zemplén. Győző Zemplén (17 October 1879 – 29 June 1916) was a Hungarian physicist who worked in the fields of hydrodynamics and the kinetic theory of gases.

Life

Győző Zemplén was born in the town of Nagykanizsa, Hungary. He grew up in Fiume. In 1896, he began his studies at the University of Budapest and, at 19 years age, won an award with an essay on the viscosity of gases. After that he began theoretical and experimental studies. In 1900 he published the essay "On the basic assumptions of the kinetic theory of gases" in the Annalen der Physik, but had been previously published mathematical works. In the same year he graduated from the University, but remained as a research assistant. In 1902 he became the assistant of Loránd Eötvös, who sent him in 1904-1905 to study abroad in Göttingen and Paris. In Göttingen he developed a mathematical treatment of the theory of shock waves, which gave him the attention of Felix Klein, who invited him to write a corresponding article in the Encyclopaedia of mathematical sciences. By applying entropy considerations (rather than only the energy theorem), he solved an open problem in the theory of shock waves in an essay "Sur l'impossibilité des ondes de choc négatives dans les gaz" in the Comptes Rendus de l'Académie des Sciences (1905). He showed that shock waves propagate only towards rarer gas layers. On his return from Paris, and his Habilitation in 1905, he became a lecturer at the University of Budapest (1905) and at the Technical University of Budapest (1907). In 1912, he became a professor at the Technical University in theoretical physics. He was also a professor at Teachers' Training College in 1908 and was active in the reform of physics teaching in Hungary. Zemplen also dealt with the then new theory of relativity, wrote a textbook on Electrodynamics (The electricity and its practical applications in 1910) and translated a book by Marie Curie on radioactivity and in 1905 wrote a book himself on this issue. 
In 1908 he became a member of the Hungarian Academy of Sciences, whose Rozsay price he received in 1911. Since 1898 he was a member of the Hungarian Society of Natural Sciences. In 1914 he became secretary of the society founded by Eötvös for the mathematical and physical sciences section and editor of its magazine. He was active also in several other societies and committees and a founding member of the football club of the University. 
In World War I, he volunteered and carried a battery of mortars on the Serbian front. For some time he lay with typhoid fever in a hospital in Klagenfurt. He fought again at the front in an offensive against the Italians at Monte Dorole in the Battle of Asiago in June 1916. At a forward observation post, he was hit by shrapnel and died shortly afterwards.

Mark 8 Fire Control Computer. The Mark 8 Fire Control Computer was developed by Bell Laboratories during World War II. It was initially requested by the USN Bureau of Ordnance as an alternative to the Ford Instruments Mark I Fire Control Computer, in case supplies of the Mk I were interrupted or were unable to be manufactured in the required numbers. The Mk 8 computer used all electric methods of computation, in contrast to the Mk 1, which performed most computations via mechanical devices. The Mk 8 was found to be more accurate than the Mk 1 and substantially faster in reaching a fire control solution, but by the time it was developed and tested in 1944, supplies of the Mk 1 were found to be sufficient in quantity. The USN extensively tested the Mk 8 and may have incorporated some of its technology into the post war Ford Instruments Mk1A computer. The Mk 8 technology was similar to that used in the M9 gun data computer used by the US Army for coast defence fire control and in the SCR-584 radar system computer.

Civilian Coupé. The Civilian Coupé is a British, single-engined two-seat private monoplane built starting in 1929. Only five were made, and it was the Civilian Aircraft Company's only product, but one still flies in the UK.

Design and development
In 1928 Harold Boultbee left Handley Page to form the Civilian Aircraft Company.  The Coupé was its only product, an aircraft of mixed metal and wood construction.  It was aimed at the private market and was quite advanced for its day.  The Coupé is a high-winged monoplane, the wing vee-strut braced to the lower fuselage longerons. The wings fold for transport and storage.  They have almost constant chord, with slight taper outboard and a gentle reduction in chord at the trailing edge to help rearward visibility.  There is glazing at the centre section for an upward view from the enclosed cabin where pilot and passenger sit in seats not quite side by side.

The fuselage has a square cross-section, decreasing in depth towards the tail and is plywood-covered.  Tail surfaces are nearly rectangular, though the rudder extends below the tailplane and elevators to the bottom of the fuselage, where it curves in smoothly.  A split-axle undercarriage is mounted from the lower fuselage with the main legs fixed to the upper longerons; there is a tailskid.  Unusually for its time, the wheels have brakes and the flying controls are pushrod-operated.

The Coupé first flew in July 1929, powered by a 75 hp (56 kW) A.B.C. Hornet air-cooled flat four engine driving a two-bladed propeller. The sole aircraft with this engine became known as the Mk.I and all later Coupés, which used the 100 hp (75 kW) Armstrong Siddeley Genet Major I five-cylinder radial, as Mk.IIs.  In both engine installations, cylinder heads are exposed for cooling.  It took about 18 months before teething problems, chiefly vibration transmitted by the engine mounting, were cured.

Operational history
In all, five Coupés were probably built and certainly five are recorded by UK Civil Aviation Authority, one of which, G-ABNT, still flies in 2010 though no others survive.   The last Mk.II built went immediately to a German owner and crashed during the war but the other three Coupés were raced in the UK between 1931 and 1933, though without great success. Later one of them was sold to a Dutch owner and the prototype also went abroad.  By 1934 the Civilian Aircraft Company had closed down and only two Coupés were active.

At present the last remaining one is based at Biggin Hill

Fisher FP-303. The Fisher FP-303 is a Canadian single-seat, low wing, conventional landing gear, single engined light kit aircraft designed for construction by amateur builders. Fisher Flying Products was originally based in Edgeley, North Dakota, USA but the company is now located in Woodbridge, Ontario, Canada.

Development
The FP-303 was designed by Fisher Aircraft in the United States in 1982 and was intended to meet the requirements of the US FAR 103 Ultralight Vehicles category, including that category's maximum  empty weight. The design goal was to provide ultralight pilots with an aircraft that was as portable as possible. To this end the aircraft's wings fold along the fuselage to rest on the horizontal stabilizer allowing trailering or storage in a small hangar or with other aircraft. The aircraft can be field assembled from its travelling state in ten minutes. The FP-303 has a standard empty weight of  when equipped with a two-stroke  Rotax 277 engine.

The construction of the FP-303 is similar to the Fisher FP-202 Koala. The aircraft's structure is entirely made from wood, with the wooden fuselage built from wood strips arranged in a geodesic form, resulting in a very strong and light aircraft with redundant load paths. Both the wings and fuselage are covered with doped aircraft fabric. The wings are strut-braced underneath to the landing gear and utilize bottom jury struts. The wing is positioned aft enough that the pilot has adequate downward visibility. Flaps and brakes are optional. The company claims it takes an amateur builder between 300–500 hours to build the FP-303.

Quonset Air Museum. The Quonset Air Museum was an aviation museum located at Quonset Point Air National Guard Station in North Kingstown, Rhode Island.

The museum's collection included military vehicles, missiles, aircraft and over 5,000 smaller aviation artifacts. An extensive archive of books, magazines, manuals, photos, documents and blueprints was preserved within the museum.

Notable aircraft in the collection included the last surviving Curtiss XF15C mixed propulsion prototype and a twin tail C-1A Trader. This one of a kind aircraft had been fitted with twin tails and radome (but without associated electronics) to serve the aerodynamic prototype for the E-1 Tracer Electronic Counter Measure aircraft. This C-1A has the distinction of being the last aircraft to fly from Naval Air Station Quonset Point upon its closure in 1974.

History
The museum recovered an F6F-5 Hellcat from Martha's Vineyard on 4 December 1993. It became the subject of a court battle after the U.S. Navy claimed that the aircraft had been salvaged without their permission. Eventually, a settlement was reached where the museum received the aircraft on loan from the Navy.

An Antonov An-2 at the museum was given to the Antonov Foundation in 2004. The following year David H. Payne Sr. became the museum president.

The museum occupied Painting Hangar #488 located at what was once the Naval Air Station Quonset Point. This 50,000 sq. ft. facility was one of only three existing specialized wood and brick hangars built during WWII. Heavy snowfall in March 2015 partially collapsed the building's roof and the hangar was condemned.

In January 2016, plans for a new museum were announced. The museum was originally supposed to leave by April 2, but it was given an extension. Later, in June, a $4 million request for state funding failed to materialize. On December 16, 2016, it was announced that the museum would not reopen. Although many aircraft in the collection have been transferred to other museums, the museum's P2V was scrapped in May 2018, as it was too large to move.
