Whitney Boomerang. The Whitney Boomerang DW200 is a two-seat, fixed tricycle gear general aviation airplane, originally designed for flight training, touring and personal use. It can be seen in active service at Darwin International, Brisbane's Archerfield and Perth's Jandakot general aviation airports.

History

The Whitney Boomerang was designed by C.W. "Bill" Whitney as a replacement for the aging two-seat training aircraft fleets. The type certificate was granted on 18 December 2007 making the Boomerang only the 5th Australian aircraft to be granted an FAR 23 certificate. The Whitney Boomerang was produced by Dean Wilson Aviation located at Kingaroy Airport until 2011, when the company went into receivership. The machine has performed at several airshows and has also featured in media reports having made the trans-Tasman journey to New Zealand.

On Friday 27 May 2011, an advertisement appeared in the Aviation supplement of The Australian newspaper inviting expressions of interest in acquiring the assets of the companies manufacturing the Whitney Boomerang. The assets were listed as the Type Certificate, aircraft, plant and equipment, parts and tooling for aircraft manufacture and the hangar housing production facilities at Kingaroy, Queensland. The advertisement was inserted under instructions from the receivers and managers of Dean-Wilson Aviation P/L and Queensland Aviation Manufacturing P/L.

A notice on the SM Aviation website states:

SM Aviation has been appointed by Price Waterhouse in Brisbane to carry out the sale of assets of Dean-Wilson Aviation and QLD Aircraft Manufacturing (receivers and managers appointed). Simon Mathews will personally oversee the sale of the business, its intellectual property and assets located at Kingaroy in Queensland, Australia.

Polybutene. Polybutene is an organic polymer made from a mixture of 1-butene, 2-butene, and isobutylene.  Ethylene steam cracker C4s are also used as supplemental feed for polybutene. It is similar to polyisobutylene (PIB), which is produced from essentially pure isobutylene made in a C4 complex of a major refinery.  The presence of isomers other than isobutylene can have several effects including: 1) lower reactivity due to steric hindrance at the terminal carbon in, e.g., manufacture of polyisobutenyl succinic anhydride (PIBSA) dispersant manufacture; 2) the molecular weight—viscosity relationships of the two materials may also be somewhat different.

Applications
Industrial product applications include, sealants, adhesives, extenders for putties used for sealing roofs and windows, coatings, polymer modification, tackified polyethylene films, personal care, polybutene emulsions.  Hydrogenated polybutenes are used in a wide variety of cosmetic preparations, such as lipstick and lip gloss. It is used in adhesives owing to its tackiness. Polybutene finds a niche use in bird and squirrel repellents and is ubiquitous as the active agent in mouse and insect "sticky traps".

An important physical property is that higher molecular weight grades thermally degrade to lower-molecular weight polybutenes; those evaporate as well as degrade to butene monomers which can also evaporate. This depolymerization mechanism which allows clean and complete volatization is in contrast to mineral oils which leave gum and sludge or thermoplastics which melt and spread. The property is very valuable for a variety of applications. For smoke inhibition in two stroke engine fuels, the lubricant can degrade at temperatures below the combustion temperature. For electrical lubricants and carriers which might be subject to overheating or fires, polybutene does not result in increased insulation (accelerating the overheating) or conductive carbon deposits.

Ferrocarril Alcoy Gandia. Ferrocarril Alcoy Gandía was a Spanish railway line in operation between 1892 and 1969. It was also known as  (Spanish) or xitxarra (Valencian).

History
The railway company, founded in 1882 was known as the Alcoy y Gandía Rail and Harbour Co Ltd, with company offices in both Alcoy and London.
Large investments in railway infrastructure were made by English companies in Spain during the late 19th century and helped to transform Spanish travel, industry and commerce. 
The main motive for English investment in a railway between Alcoy and Gandia was to promote the export of coal from England to supply the growing industry found in the area.

Railway construction was supervised and implemented by the Ravel Lucien Company.

The inaugural journey took place on July 18, 1892.

The line had connections with the Railway Company Villena to Alcoy and Yecla (V.A.Y.) 
sharing material and facilities, according to a contract signed on 13 October 1908.

The total length of the line was 53,355 m, with a height of 530 m between Alcoy  and Gandia.

Stations
The stations and halts were located in the towns of: Puerto de Gandia - Gandia harbour (0 km); Gandia (3 km); Almoines (7 km); Beniarjó (9 km); Potríes (11 km); Villalonga (14 km); Lorcha (27 km); Beniarrés (34 km); Gayanes (37 km); Muro de Alcoy (43 km); Cocentaina (46 km); Alcoy (53 km).

Locomotives
The locomotive fleet consisted of eight 2-6-2T steam locomotives manufactured by Beyer, Peacock & Company, Manchester between 1890 and 1891. Each locomotive was named after a station served by the railway.

Locomotive no. 2 "Villalonga" is set on a plinth in the Al-Azraq area of Alcoy, which was the terminus of the railway. Locomotive no. 7, "Cocentaina" is set on a plinth at Gandía. Both preserved locomotives are able to be viewed by the public and can be photographed easily in situ.

Museum
There is museum in Almoines, run by Asociación Tren Alcoy-Gandía. The current chairman José Morales and the current secretary is Isidro Ferrando.

Active Wheel. Active Wheel was a Michelin-developed tire which incorporates an electric motor and suspension It was presented at Challenge Bibendum 2004's edition on the Hy-Light concept car and showcased during Paris Motor Show "Mondial de l'automobile"in 2008 both on the Venturi Volage electric sports car and on the Heuliez Will. The project was interrupted in 2014.

Like other in-wheel motors, the ActiveWheel design provides direct power delivery of approximately , as well as regenerative braking. In addition, it replaces a mechanical suspension with an active suspension driven by an in-wheel electrical suspension motor that controls torque distribution, traction, turning maneuvers, pitch, roll and suspension damping for that wheel. However, the effects of shocks, water and snow to such an "in-wheel" design have not been precisely studied.

Siemens VDO, developing a similar concept called eCorner, was purchased by Continental in 2007.

Engine crane. An engine crane (also referred as engine hoist) is a common repair tool used in vehicle repair shops to remove or install gasoline or diesel engines in small and crowded vehicle engine compartments. It uses a heavy cantilevered support structure to hold the engine in mid-air so that the mechanic can carefully connect or disconnect fragile hoses and wires on the engine to the frame of the vehicle.

The engine crane is commonly used in combination with the engine stand so that the removed engine can be rotated in midair to provide access to underside surfaces of the engine.

Construction 
Engine cranes are typically mounted on large casters so that an engine can be lifted straight up out of an engine compartment and then rolled away from the immobile vehicle frame.

Most engine cranes are equipped with a telescopic boom which can be extended to reach engine blocks located further into the engine compartment. At the end of the boom there is a grab hook where lifting chains, slings or a load leveler can be attached for lifting purposes.

Types of engine cranes
Engine cranes/hoists have three commonly used types: hydraulic hoists, chain hoists, and electric chain hoists. The type of engine crane is chosen based on the amount of weight the user is lifting, cost, and convenience.

Hydraulic hoist
The most commonly used engine crane is the hydraulic hoist. The simplicity of a hydraulic hoist also makes this hoist the most economical engine crane. A hydraulic hoist is generally made of an adjustable arm, hydraulic jack, frame, and a set of legs. The crane arm, with multiple lengths and weight capacities, has a hook on the end that connects a chain to the engine. The arm of the hydraulic engine hoist raises and lowers with the use of a hydraulic jack, which is operated with a bar that pumps the hydraulic jack to raise the arm. To lower the arm, pressure is released from the hydraulic jack.  To support the hydraulic arm, a frame with a set of legs stabilizes the weight of the engine. Most hydraulic engine cranes have casters, which help to efficiently relocate the engine crane.

Chain hoist
Chain hoists are ceiling-mounted engine cranes that are often slower than hydraulic hoists and electric chain hoists. Chain hoists utilize a system of gears and chains to multiply forces that are produced when the operator is pulling the chain to lift the engine. A braking system prevents the engine from unintentionally lowering by the user. Chain hoists are often inexpensive and easy to operate but do require the chain hoist to be mounted, unlike a movable hydraulic hoist.

Electric chain hoist
The electric chain hoist, also known as the "electric hoist", is the least used type of engine crane. The operation is similar to the chain hoist in the way that chains are used to lift the engine. The electric chain hoist uses an electric motor operated by remote control to lift the engine, unlike the chain hoist where the operator has to manually pull a chain. Although the electric chain hoist is faster in operation, this hoist is also more costly than a chain hoist.

Messerschmitt Bf 161. The Messerschmitt Bf 161 was a 1930s prototype German reconnaissance aircraft.

Development
The Bf 161 was a specialised reconnaissance aircraft, based on the Bf 110, and similar to the Bf 162, designed as a light bomber. The prototype V1 was powered by two Junkers Jumo 210 inline engines and first flew on 9 March 1938. It was followed by a second prototype, V2, powered by two Daimler-Benz DB 600a engines which first flew on 30 August 1938.

The aircraft did not enter production, as it was soon decided that a new aircraft type was not needed, and variants of the Bf 110 could perform the reconnaissance role.

Operational history
The two prototypes were used for research and development, and V2 was used in Augsburg for towing the Me 163A Komet, later moving to Peenemünde to continue towing.

Radiant AI. The Radiant AI is a technology developed by Bethesda Softworks for The Elder Scrolls video games. It allows non-player characters (NPCs) to make choices and engage in behaviors more complex than in past titles. The technology was developed for The Elder Scrolls IV: Oblivion and expanded in The Elder Scrolls V: Skyrim; it is also used in Fallout 3, Fallout: New Vegas and Fallout 4, also published by Bethesda, with 3 and 4 being developed by them as well.

Technology
The Radiant AI technology, as it evolved in its iteration developed for Skyrim, comprises two parts:

Radiant AI
The Radiant AI system deals with NPC interactions and behavior. It allows non-player characters to dynamically react to and interact with the world around them. General goals, such as "Eat in this location at 2pm" are given to NPCs, and NPCs are left to determine how to achieve them. The absence of individual scripting for each character allows for the construction of a world on a much larger scale than other games had developed, and aids in the creation of what Todd Howard described as an "organic feel" for the game.

Radiant Story
The Radiant Story system deals with how the game itself reacts to the player behavior, such as the creation of new dynamic quests. Dynamically generated quests are placed by the game in locations the player hasn't visited yet and are related to earlier adventures.

Hanriot HD.7. The Hanriot HD.7 was a French fighter prototype of the 1910s.

Development
The HD.7 was based largely on the Hanriot HD.3, using the wings and tail surfaces from the earlier model. A single-seat fighter, it first flew in 1918

Operational history
The aircraft was designed to replace the SPAD S.XIII fighter. However, after its first flight in 1918, it was found to be of good performance, but inferior to its main competitor, the Nieuport-Delage NiD 29, which then entered service production for the Aéronautique Militaire in 1918. No further production occurred.
