Robert Urie. Robert Wallace Urie (22 October 1854 – 6 January 1937) was a Scottish locomotive engineer who was the last chief mechanical engineer of the London and South Western Railway.

Career
After serving an apprenticeship with and working for various private locomotive manufacturers he joined the Caledonian Railway in 1890, and became chief draughtsman, and later Works Manager at St. Rollox railway works under Dugald Drummond. In 1897 he moved with Drummond to join the London and South Western Railway (LSWR) as works manager at Nine Elms in London. He transferred to the new works at Eastleigh in 1909.
Following the death of Dugald Drummond in 1912, Urie became chief mechanical engineer until his own retirement at the grouping of 1923.

Locomotive designs

Robert Urie made a significant contribution to the development of more powerful express passenger and goods locomotives for use on the London and South Western Railway main line, with simple yet robust designs. In particular his LSWR H15 class, LSWR N15 class and LSWR S15 class 4-6-0 as well LSWR Class G16 4-8-0T and LSWR H16 class 4-6-2T locomotives continued to be built by the Southern Railway under Richard Maunsell's direction.

Vertical Flight Society. The Vertical Flight Society, formerly the American Helicopter Society (AHS), is the non-profit technical society for the advancement of vertical flight. It has 21 different technical committees and two dozen active chapters around the world. There are over 100 corporate members and 28 educational members.

Each year, the Society organizes or co-sponsors several regional and international conferences that facilitate the advancement of the theory and practices of helicopter and other VTOL aircraft technology, and publishes their proceedings. Its AHS Forum is the largest vertical flight technical conference in the world, with over 1200 attendees.

Formed in 1943 as the American Helicopter Society, it publishes a general audience vertical flight technology magazine, Vertiflite, as well as one of the only technical publication devoted solely to vertical flight, The Journal of the American Helicopter Society (JAHS), published quarterly. The society advocates on behalf of rotorcraft technology to the public and to government bodies. The Vertical Flight Society also awards nearly $100,000 or more in annual scholarships and sponsors an annual student design competition for university undergraduate and graduate student teams.

The Society was renamed to VFS in April 2018 to better reflect its mission: even though the Society was founded with the word "American" in its name, the membership was international; and the focus is all vertical flight aircraft, including non-helicopter rotorcraft (such as the V-22 Osprey), jet-borne V/STOL (such as the AV-8 Harrier and F-35 Lightning II), electric VTOL, and other non-conventional configurations.

Armstrong Siddeley Python. The Armstrong Siddeley Python was an early British turboprop engine designed and built by the Armstrong Siddeley company in the mid-1940s. Its main use was in the Westland Wyvern, a carrier-based heavy fighter. The prototypes had used the Rolls-Royce Eagle piston engine, but Pythons were used in production aircraft. In this application, the Python was rated at 4,110 equivalent shaft horsepower (eshp).

Design and development
The design started as an experimental pure-turbojet known as the ASX, which commenced testing in 1943. By this point other engine designs were already entering pre-production, and it seemed there was little need for the ASX in its existing form. The design was then modified by the addition of a reduction gearbox to drive a propeller. The turboprop thus formed was named ASP.

Flight testing
Early flight-testing of the Python was carried out using the Lancaster B.1 (FE) TW911 and the Lincoln B.2 RE339/G: in each aircraft Pythons replaced the two outboard Rolls-Royce Merlins.

Lincoln B.2 RF403 had two Pythons similarly installed and was used for high-altitude bombing trials at Woomera, South Australia. These trials were principally of the ballistic casings for the Blue Danube atomic weapon: the Lincoln was the only available aircraft that could accommodate the large weapon casing, measuring 62 inches diameter x  in length. The Pythons were fitted to increase the height from which tests could be carried out. Maximum release height and speed for the first eleven tests was 275 mph and  with a bombing error of 61 ft.

Python Engine on public display
An Armstrong Siddeley Python is on display at the East Midlands Aeropark Castle Donington.

Henry Timken. Henry Timken (August 16, 1831 in Bremen, Germany – March 16, 1909 in San Diego, California) was an inventor and businessman who founded the Timken Roller Bearing Company, later called the Timken Company. His family migrated to the United States when he was 7 years old. He began his business career in the St. Louis region. His inventions of an improved carriage spring and an improved roller bearing brought him the money needed to create a company dedicated to the latter.

Biography
Henry Timken was born in Bremen, now in Germany, and emigrated to the United States with his family when he was seven years old. The Timkens settled in Sedalia, Missouri; Henry left the family farm to apprentice under carriage-builder Caspar Schurmeier. Timken opened his own carriage-building company in St. Louis in 1855, and introduced several improvements to the carriages his firm produced, including his patented "Timken buggy spring", which made him a fortune.

He patented an improved tapered roller bearing in 1898. A year later, he established the Timken Roller Bearing Axle Company which grew rapidly as the product was in great demand by cars, trucks, and tractors. By 1923, 90% of the country's production of bearings came from Timken. His slogan "Wherever wheels and shafts turn", describes the widespread use for bearings—trains, conveyors, elevators, aircraft engines, even space shuttle landing wheels.

He first retired in 1887 and settled in San Diego, California, but regretted retiring in 1891 and went back to St Louis. He later returned to San Diego for a second retirement before dying there in 1909. His last residence still stands, and is known as Timken House. The nearby Timken Museum of Art in Balboa Park bears his family's name, as it was established with his fortune.

Honors 
Timken was inducted into the National Inventors Hall of Fame on September 19, 1998. Henry Timken was one of six inducted into the hall of fame at ceremonies held at the E J Thomas Hall in Akron, Ohio. William Robert Timken Jr., Timken's great-grandson, the retired chairman and chief executive officer of The Timken Company and later United States Ambassador to Germany, received the award on behalf of his great-grandfather.

Allison V730. The Allison V730 is a three-speed automatic transmission used in several makes of transit bus including the RTS, Canadian-produced Classic buses derived from the GM New Look, and Grumman Flxibles.  Later production buses in the GM and Flxible line had the Allison V731 transmission, which is essentially the same unit but controlled electronically, with a keypad replacing the familiar shifter-lever in the driver's compartment.

The Allison V730/V731 family transmissions moreover come in versions with a built-in retarder (the VR731), and a version allowing transit agencies and others to use right-turning Detroit Diesel family motors (variously the V731R or V731RH) instead of the standard left-turning units found in Flxibles, GM New Looks and RTS equipment.

Most installations of the V730/V731 have them coupled to the DDA 6V92TA two-stroke diesel engine, with the exception of GM 'Classic' T6H-5307 buses produced in Canada, where these were instead mated to the then-standard 6V71N engine.  Some Canadian production 1982 "New Look" models featured the 6V92 mated to the V730, such as Vancouver, B.C.'s 1982 T6H-5307 "Hillclimber" buses. An example resides at "TRAMS" in British Columbia.

Hawker Hedgehog. The Hawker Hedgehog was a three-seat reconnaissance biplane, to be used for naval scouting, produced to meet Air Ministry Specification 37/22.

It was designed in 1923, and had its first flight the next year, piloted by F. P. Raynham.
The crew consisted of the pilot, an observer and an air gunner. Its construction was typical of the period: a wooden structure covered with fabric. The powerplant was a nine-cylinder Bristol Jupiter IV radial engine driving a two-bladed wooden propeller.

While testing was successful, on completion of the flight tests, the project was cancelled. This was due to the Hedgehog's performance not being sufficiently better than the existing aircraft used for naval reconnaissance, the Avro Bison and Blackburn Blackburn. Consequently, only one prototype was built. The armament of the aircraft was one fixed forward-firing .303 in (7.7 mm) Vickers gun and one .303 in (7.7 mm) Lewis gun on a Scarff ring in the rear cockpit. The aircraft was fitted with floats that contained wheels to enable use as an amphibian. The wings could be folded, so that the width was reduced to 16 ft 7½ in (4.87 m) for storage.

Zincke–Suhl reaction. The Zincke–Suhl reaction is a special case of a Friedel-Crafts alkylation and was first described by Theodor Zincke and Suhl in 1906. Unlike the traditional Friedel-Crafts reaction, the reduction of the phenyl ring leads to a higher energy final product that can be used as starting material in the dienol–benzene rearrangement, among other reactions.

The classic example of this reaction is the conversion of p-cresol to a cyclohexadienone (with the aid of aluminium chloride as a catalyst and tetrachloromethane as a solvent). Melvin Newman, a scientist from the U.S. intensively studied the reaction in the 1950s and reported several improved procedures as well as mechanistic studies. Since then, studies investigating the impact of alternate reagents have been conducted by others.

Mechanism

Aluminum chloride plays a range of functions in this reaction, first reacting with p-cresol to form phenoxy aluminum chloride along with a molecule of hydrogen chloride. Additionally, aluminum chloride activates a molecule of tetrachloride that in turn is subjected to a nucleophilic attack by the phenoxy aluminum chloride. Subsequently, the product interacts with aluminum chloride and tetrachloride again to form a loose complex. Finally, the product is treated with water, resulting in the final product.

Catalysts 
During a series of tests, Newman found that utilization of carbon disulfide as a solvent was demonstrated to improve the yield. As an example, addition of a solution of p-cresol and carbon disulfide to a suspension of aluminum chloride and carbon disulfide resulted in a 20% improvement in yield.

Applications
Zincke-Suhl products can be used as starting reagents for the dienol benzene rearrangement. This is an important reaction for artificially producing biologically relevant molecules including the A ring of steroids.

Perhaps the most intriguing application of the Zincke–Suhl reaction is its potential following von Auwers rearrangements. Demeunier and Jaeckh described how such rearrangements may result in the formation of high energy intermediates. For example, reformation of the aromatic ring from the semibenzene (cyclohexadienone) follows an energy drop of just under 36 kcal/mol. Such staunch drops have been experimentally shown to lead to efficient aromatization with high yields.

Other products including dioxocins and polymers can form depending upon the location of the initial addition of carbon tetrachloride. Furthermore, changes to the reagents such as the use of chloroform instead of carbon tetrachloride can form additional products.

Above: Ortho-addition of tetrachloride to phenoxy aluminum chloride can produce 6,12-diphenyl-2,8-dimethyl-6,12-epoxy-6H, 12H-dibenzo[b,f][1,5] dioxocin, a high-melting, white polymer.

Keith Turner (businessman). Keith Sharman Turner  (born 1950) is a New Zealand businessman. He is a Fellow of Engineering New Zealand. In 2025 he was appointed a Companion of the New Zealand Order of Merit, for services to the electricity industry. In September 2007, New Zealand Listener magazine placed Turner in 14th position in its 2007 Power List of the 50 most powerful people in New Zealand, down from 12th in the 2006 Power List and 42nd place in  2005.

Early life and education
Turner was born in New Zealand in 1950. He completed a Bachelor of Engineering and a Master of Engineering at the University of Canterbury, followed by a PhD in electrical engineering in 1980.

Career
Turner's early career was in the New Zealand electricity industry, in which he began in 1969.
 Managing director, DesignPower, a professional engineering consultancy to the electricity industry
 Chief Operating Officer, Electricity Corporation of New Zealand prior to its breakup in 1999
 Chief Executive, Meridian Energy, 1999 to 2008.
 Deputy Chairman, Auckland International Airport, Director since 2004
 Director, Spark Infrastructure
 Chairman, Fisher & Paykel 2011
 Member of the Interim Climate Change Committee, 2018

Renewable energy
Turner has expressed interest in social, economic and environmental sustainability, and renewable energy in New Zealand.  In The case for renewable generation in 2004 he said: "The choices we make – you and I and the rest of New Zealand – the choices we make over the next few years, are going to shape the energy structure of our society for at least the next one, and possibly the next two, generations".

According to Turner, a viable transmission grid is an important ingredient of his renewable energy strategy. He has been critical of the lack of investment in the electricity transmission grid in New Zealand by the state-owned enterprise Transpower. In November 2005, he advised that "New Zealand's electricity grid is so overworked that some lines cannot be taken out for servicing", which was vindicated by the 2006 Auckland Blackout, when half of Auckland lost power during a storm because an earth wire snapped and fell on switching equipment.

Turner is part owner of Waitaki Wind Limited, a company investigating wind farms in Otago.

Simpli. Simpli was an early search engine that offered word-sense disambiguation to search terms.  A user could enter in a search term that was ambiguous (e.g., Java) and the search engine would return a list of alternatives (coffee, programming language, island in the South Seas).

The technology was rooted in brain science and built by academics to model the way in which the mind stored and utilized language.  The early technology was derived heavily from WordNet, which was invented by George A. Miller at Princeton University.  George Miller was an advisory Board member to Simpli.

Simpli was founded by a number of graduate students, post-doctoral fellows, and professors meeting in the Department of Cognitive and Linguistic Sciences at Brown University.  Graduate students included the CEO Jeff Stibel, David Landan, and John Santini.   Post-docs included Andrew Duchon and Paul Allopenna.   Professors included James A. Anderson and Steve Reiss from Brown University, Dan Ariely from the MIT Sloan School of Management and George Miller from Princeton.

Simpli was sold in 2000 to NetZero.  Another company that leveraged the Simpli WordNet technology was purchased by Google and they continue to use the technology for search and advertising under the brand Google AdSense.

In 2001, there was a buyout of the company and it was merged with another company called Search123.  Most of the original members joined the new company. That company was later sold in 2004 to ValueClick, which continues to use the technology and search engine to this day.

GER Class P43. The GER Class P43 was a class of ten 4-2-2 steam tender locomotives designed by James Holden for the Great Eastern Railway. They were the last 'singles' built for the Great Eastern, and the last in service.

History
Constructed with oil-burning apparatus to speed the elite from the City of London to Cromer, West Runton & Sheringham and capable of reaching North Walsham non-stop in just over two and a half hours. They had  inside cylinders and  driving wheels.

Only a single batch of ten was built, all on order P43 in 1898, numbered 10 to 19. They had a short working life, as they were incapable of handling increasing heavy trains. They were withdrawn between 1907 and 1910.
