Tetrabromoethylene. Tetrabromoethylene is a brominated derivative of ethylene. Tetrabromoethylene is a potential fungicide and bactericide on fruits. It was used in mineral separation.

It is prepared from acetylene and bromine in multiple steps. One method involves dehydrobromination of pentabromoethane, other method involves bromination of dibromoethylene in chloroform. Reaction of mercuric acetylide and bromine also gives tetrabromoethylene. It can be produced by oxybrominating butane with free oxygen and bromine. 

Tetrabromoethylene gives tribromoacetyl bromide upon treatment with fuming nitric acid.

George H. Prudden. George Henry Prudden, Jr. (February 18, 1893 – January 20, 1964) was an American aircraft engineer. He was instrumental in designing the first all metal aircraft in America. He was president of the Early Birds of Aviation in 1961.

Early life 
Born on 18 February 1893, George, and his brother Earl, were interested in aviation from an early age, being featured in the St. Louis Post-Dispatch with an airplane model of his design in 1909. By 24 June 1910, Prudden had soloed a plane of his own design based on the Wright Flyer.

Despite his flying experience, George Prudden served in the 74th Field Artillery during World War I. After military service Prudden returned to education graduating in the Class of 1920 from the University of Minnesota. George was then recruited by William Bushnell Stout, to help develop the Stout ST-1 all metal torpedo bomber for the U.S. Navy. George later designed the Stout 2-AT Pullman, the first aircraft to make regularly scheduled airline flights, cargo flights, and commercial air mail flights. Henry Ford fully purchased the Stout company in 1925, making it the Stout Metal Airplane Division of the Ford Motor Company. One of Prudden's first tasks was to investigate the breakup of the USS Shenandoah on behalf of Ford. Ford was very displeased when he saw that the effort was publicised in the Detroit Free Press and cut Prudden.

In 1927, Prudden founded the Prudden-San Diego Airplane Company, to manufacture an all-metal trimotor with Ryan supplied engines. In November 1928, Prudden left the company at the height of the depression and the company was renamed to the Solar Aircraft Company. The company Prudden founded is still active as Solar Turbines Incorporated, a wholly owned subsidiary of Caterpillar Inc.

Later, Prudden developed the Prudden-Whitehead monoplane with the Atlanta Aircraft Corporation. While in Atlanta, Prudden helped develop Candler Field, Atlanta.

In 1932, Prudden worked for Lockheed Aircraft where he helped engineer the Lockheed Vega and Lockheed Orion aircraft.

In World War II, Prudden managed the Ryan Aeronautical factory in San Diego, California.

In 1961, Prudden became the President of the Early birds of Aviation.

He died on January 20, 1964.

Legacy
Many of Prudden's awards were displayed in the San Diego Air & Space Museum, but were destroyed in a 1978 arson fire.

Honor Award. The National Building Museum promotes excellence in architecture, engineering, construction, planning, and design. In furtherance of that mission, the Museum instituted an annual Honor Award in 1986 to recognize individuals and organizations that have made important contributions to the U.S.'s building heritage. Recipients are selected from a wide variety of backgrounds to call attention to the many factors that determine the form and quality of the built world.
Past recipients include ex-First Lady Lady Bird Johnson, who was honored in 1995 for her lifetime leadership in beautification and conservation campaigns. Michael Eisner and The Walt Disney Company were honored in 2001 in recognition of their commitment to architecture, commissioning postmodernist architects such as Michael Graves, Robert A.M. Stern, Frank Gehry, and Arata Isozaki. In 2010, Perkins and Will became the first architecture firm ever to receive the prize for "designing buildings that promote the health of occupants, conserve resources, and unify communities," in the words of Museum executive director Chase W. Rynd.
The National Building Museum also bestows two other major awards: the Vincent Scully Prize to recognize exemplary practice, scholarship, or criticism in architecture, historic preservation, and urban design and the Henry C. Turner Prize for Innovation in Construction Technology.

General Micro-electronics. General Micro-electronics (GMe) was an American semiconductor company in the 1960s. It was formed by three former members of Fairchild Semiconductor, and is thus one of the "Fairchildren". It was acquired in 1966 by Philco-Ford and became their Microelectronics Division.

With Frank Wanlass as director of research and engineering, GMe was the first company to design, fabricate, and sell MOS integrated circuits. The first MOS chips were small-scale integrated chips for NASA satellites. In 1964, Wanlass demonstrated a single-chip 16-bit shift register he designed, with an incredible (for the time) 120 transistors on a single chip.

That same year, the company entered an agreement to convert a Victor Comptometer tube-based electronic calculator to all-IC form, the Victor 3900, with a planned introduction in early 1966. The task proved to be much more difficult than expected, and GMe was left almost insolvent. The company was purchased by Philco-Ford, at which time Victor gave up on the product. They remarketed the system as the Philco 3900, but by the time it was ready for market, a less-expensive alternative had appeared.

Several members of the GMe team would go on to found Electronic Arrays and produce a six-chip calculator system that was successful in the early 1970s.

Matra M.04. The Matra M.04 was a French missile project that began development in  Societe Matra in 1948. Intended either as an air-to-air missile or a surface-to-air missile it was never adopted in service, although it was tested over the Sahara in 1952.

Development
The missile was first test-fired in flight from a Halifax bomber in May 1950 at Colomb-Bechar. The missile was large for an air-to-air missile, with two pairs of cruciform swept wings, with the smaller rear pair being moved using pneumatic actuation to provide steering. A SEPR acid/aniline rocket containing 110 kg of propellent provided 1,250 kg of thrust for 14 seconds, taking it to a speed of 490 meters per second.

The surface-to-air version was intended to have an additional tandem booster stage, and was designated the R.042 - and work continued on it until 1955.

Ministry of Medium Machine-Building. The Ministry of Medium Machine-Building (, also known as Sredmash) was a government ministry of the Soviet Union which supervised the Soviet nuclear industry, including production of nuclear warheads.

History
The ministry was established on the basis of the First Chief Directorate (nuclear industry) and the Third Chief Directorate (development in the area controlled missiles, aircraft, rockets and long range missiles) of the Council of Ministers of the USSR as well as the Central Board of Industrial Building of the Ministry of Internal Affairs of the USSR (Главпромстрой МВД) charged with construction of nuclear installations, all of which were in operation since September 1942.

The Ministry of Medium Machine Building was established by a Decree of the Presidium of the Supreme Soviet on 26 June 1953. The Central Intelligence Agency initially believed that the ministry oversaw the war industry. On September 11, 1989, after merging with the Ministry of Atomic Energy, the Ministry of Medium Machine Building was renamed the Ministry of Atomic Energy and Industry of the USSR  (Министерство атомной энергетики и промышленности СССР).

HMIS Bihar (J247). HMIS Bihar (J247) was a  built for the Royal Navy. It transferred to the Royal Indian Navy (RIN) during the Second World War.

Design and description
The Bangor class was designed as a small minesweeper that could be easily built in large numbers by civilian shipyards; as steam turbines were difficult to manufacture, the ships were designed to accept a wide variety of engines. Bihar displaced  at standard load and  at deep load. The ship had an overall length of , a beam of  and a draught of . The ship's complement consisted of 60 officers and ratings.

She was powered by two vertical triple-expansion steam engines (VTE), each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of  and gave a maximum speed of . The ship carried a maximum of  of fuel oil that gave her a range of  at .

The VTE-powered Bangors were armed with a QF 12-pounder (7.62 cm) anti-aircraft gun and a single QF 2-pounder (4 cm) AA gun or a quadruple mount for the Vickers .50 machine gun. In some ships the 2-pounder was replaced a single or twin  20 mm Oerlikon AA gun, while most ships were fitted with four additional single Oerlikon mounts over the course of the war. For escort work, their minesweeping gear could be exchanged for around 40 depth charges.

Construction and career
HMIS Bihar was ordered in 1940 and built at Garden Reach Shipbuilders & Engineers in Kolkata, India. She was commissioned into the RIN in 1944. Bihar was a part of the Eastern Fleet, and escorted numerous convoys between Africa, British India and Australia in 1944-45.

On 15 July 1944, the British merchant ship Tanda was torpedoed and sunk by  in the Arabian Sea at position  northwest of Mangalore. HMIS Bihar with  rescued 197 surviving crew of the Tanda. She was scrapped in 1949.
