Tyne Renewable Energy Plant. Tyne Renewable Energy Plant (or Tyne REP) was a proposed biomass power station, to be built on the north bank of the River Tyne at North Shields. The plant was developed by MGT Power, along with their similar project, the Teesport Renewable Energy Plant on Teesside. It was expected to have a generating capacity of 295 megawatts, enough to power around 600,000 homes, meaning it would have been one of the biggest of its kind in Europe. It was originally hoped the plant would be opened in 2014, costing £400 million.

The plant was planned to be built on a  industrial site at the Port of Tyne in North Shields adjacent to the proposed North Shields Bio Diesel Plant on the north bank of the River Tyne.  The construction of the plant was estimated to create around 600 jobs, as well as 150 full-time jobs once the plant was completed, and 300 to 400 indirect jobs in the supply chain. It was expected to have added an annual spend of £30 million in the local economy.

As of 2016, MGT were no longer actively pursuing plans for the plant.

Evertune. EverTune is an American company that produces the EverTune bridge, designed to keep guitar strings in tune.

Background

Stringed instruments, particularly guitars, have a tendency to get out of tune during playing, especially if strings are bent. In the late 1980s, Gibson developed a system called the Gibson Robot Guitar which used an onboard computer, motors, and a battery to keep the instrument in tune, but the system was complex and did not gain much marketplace acceptance, according to one report.

Guitarist and engineering student Cosmos Lyles came up with a device to keep his guitar in tune, and with the help of engineer Paul Dowd produced a prototype of the EverTune bridge, which uses a spring and lever system that maintains string tension.

Invention

The EverTune bridge keeps a guitar in tune despite changes in tension. The mechanical device maintains a constant state of tension despite changes in temperature or humidity or the exertion of pressure on the string.

On a guitar, the bridge has six springs and levers, one for each of a guitar's six strings, such that "when a string stretches or slips, the springs apply the opposing force necessary to compensate for the shift, thus maintaining the correct tension and tuning." In theory, the device can work with any stringed instrument, according to the inventors. The mechanism has been patented. A guitar with one installed is no longer tuned by turning the pegs at the end of the guitar's neck but rather with a screw on the bridge.

Marketing
The chief executive officer is Mark Chayet who had previously founded a manufacturing firm named Evermark which made CDs and DVDs. Chayet provided some of the initial financing for the firm, and other executives and entrepreneurs include David Weiderman, William Quigley, and Brock Pierce. The firm raised $800,000 in cash in May 2010, according to one report. One of the first guitars to have an EverTune bridge fitted in the factory is the VGS Radioactive TD-Special. A Tommy Denander signature guitar was created by the German luthiers of VGS. The EverTune bridge has hit the market in North America in October 2010 but the first series is by installation only. The unit was displayed at the Consumer Electronics Show in 2010. The product was highlighted in a feature in The New York Times entitled The Year in Ideas. In August 2011, the product was not yet ready for sale. One report suggested that EverTune will be available on a "wide range of electric guitars" in the near future and will be available as an installation kit. One report suggested there were 35 guitars with Evertune installed or about to be retrofitted with them. There are talks with guitar makers of electric guitars and basses to have the device embedded into new models and it is featured on the Ola Englund signature series of Washburn Guitars.

BEI-Teesside. BEI-Teesside is a planned biomass power station, expected to be built on the River Tees at Port Clarence, County Durham, England.

Development
The scheme was first announced in late 2009. It was developed by Bio Energy Investments (BEI), and the plant designed by Heatherwick Studio. The plant was granted planning permission on 17 March 2010, with construction expected to start later that year. The plant was expected to be completed in 2012, at a cost of £150 million, creating 200 construction jobs and 40 full-time jobs when the plant is complete.

The land earmarked for the construction of the plant is a 6-hectare brownfield site alongside the Middlesbrough Transporter Bridge, unused for 50 years since the Clarence Iron Works were demolished. The plant would occupy 2 hectares of the site, with the rest being landscaped.

The prospect of the plant being built  was initially put into doubt in June 2011 when BEI announced that without financial support from the Government, they would cancel the scheme, with the company being wound up. Construction began in January 2016.

Specification
The plant is expected to be fueled by reprocessed pine kernel shells, to generate 49 megawatts of electricity, enough to power 50,000 homes.

Aero HC-2 Heli Baby. The Aero HC-2 Heli Baby is a two-seat general-purpose light utility helicopter, designed by engineer Jaroslav Šlechta, and produced by the Czechoslovak company Aero Vodochody in the 1950s. It has a three-blade main rotor, and a two-blade tail rotor. The helicopter has an entirely metal frame and cockpit, and windows made of Plexiglas. It was the first and the only Czechoslovak-designed helicopter to be produced.

Design and development
The HC-2 was designed by a team working at Aero Vodochody led by engineer Jaroslav Šlechta, building on experience gained in the design of Šlechta's earlier Praga XE-II prototype. Construction of the prototype began in 1951, and testing commenced in 1954. The first flight occurred on December 3, 1954, and the helicopter was introduced to the public in 1955 at the Brno Industries Fair. Production was slated to begin in 1957, however, engine problems delayed it. 

An initial order of 200 of these helicopters was announced. The Czechoslovak Air Force was a user of the HC-2, as was the Czechoslovak People's Army. The Heli Baby was capable of carrying a pilot and  of cargo over a distance of , while using  gallons of fuel. In 1959, it was one of the world's lightest two-seated helicopters. Initially powered by an  Praga DH engine, the more powerful  Avia M 110H engine, designed specifically for use in helicopters, replaced it after approximately six years. The Heli Baby can be used for transport, training, and various "other duties in military and civil service". Cargo space is situated behind the helicopter's two seats. The non-retractable undercarriage has three wheels in a tricycle configuration.

Bomb Alarm System. The Bomb Alarm System (also known as the Bomb Alarm Display System) was a US and UK network of optical bhangmeter sensors intended to confirm the detonation of an enemy nuclear weapon near cities or military installations within the US or at US operated early warning radar sites in the UK or Greenland.

The BAS was designed by Western Union in 1959 and was in full operation by 1962.  The BAS was the responsibility of the 9th Space Division.  The BAS operated until 1967.

The BAS sensors were designed to report the occurrence of a nuclear flash via telephone or telegraph lines before the sensor was destroyed by the explosion.  They were designed to ignore spurious signals from lightning, sunlight, or electrical surges.

F-1 (nuclear reactor). The F-1 (from "First Physical Reactor") is a research reactor operated by the Kurchatov Institute in Moscow, Russia.  When started on December 25, 1946, it became the first nuclear reactor in Europe to achieve a self-sustaining nuclear chain reaction. It was still in operation in the beginning of the 2010s, with a power level of 24 kW, making it, at that time, the world's oldest operating reactor. The fuel in F-1 is metallic uranium with the natural content of the 235 U isotope (0.72%), graphite as a moderator, and cadmium rods to control the neutron flux. The spherical structure with a diameter of about 6 meters is made of loose graphite bricks. The graphite stack has holes in which fuel and control rods are placed, as well as research and control equipment. The weight of graphite is 400 tons, uranium is 50 tons.

Thermal power of the reactor is from 100 W to 1 MW. Air cooling, if necessary, was provided by fans. Long-term operation at high power was not possible, but the large mass of the core allowed a short-term increase in power to peak values. In November 2016 it was in permanent shutdown state.

USS Luce Bros.. USS Luce Bros. (SP-846) was a United States Navy patrol vessel in commission from 1917 to 1919.

Luce Bros. was built as a commercial "Menhaden Fisherman"-type fishing trawler of the same name in 1877 by the Alberton & Douglas Machine Company at New London, Connecticut. She was rebuilt in 1912-1913 by the White Shipbuilding Company at Sharptown, Maryland.

On 3 May 1917, the U.S. Navy acquired Luce Bros. from her owner, the Dennis Fish & Oil Company of Cape Charles, Virginia, for use as a section patrol boat during World War I. The Navy took delivery of her in July 1917, and she was commissioned at Berkley, Virginia, as USS Luce Bros. (SP-846) on 9 August 1917.

Assigned to the 5th Naval District and based at Norfolk, Virginia, Luce Bros. served in the Norfolk and Hampton Roads area on harbor patrol and guard ship duty and in naval intelligence operations for the rest of World War I.

Luce Bros. was decommissioned on 24 January 1919 and returned to the Dennis Fish & Oil Company on 28 March 1919.

Jerome Street Bridge. The Jerome Street Bridge is an arch bridge across the Youghiogheny River connecting the east and west banks of the Pittsburgh industrial suburb of McKeesport, Pennsylvania. The bridge is a rare steel crescent arch bridge. A crescent arch is formed when the intrados and extrados (the ribs) of the arch are not parallel, but instead form two different curves beginning and ending together. The ribs form a truss at the top of the arch and join together in a solid rib at each end. A crescent arch is a two-hinged arch, the ribs are further apart where the bending moment is greatest and close together at each hinge where it is minimized.

History and architectural features
This bridge was engineered by George S. Richardson. A Great Depression-era public works bond was provided to fund the creation of a new auto-centric four-lane highway bridge.

The bridge was dedicated on May 3, 1938 and opened to traffic on May 4. Thousands of people attended the ceremony and parade to celebrate the new bridge. The total cost of the new bridge was $667,000.

 Originally, the Fifth Avenue Bridge stood on the site. This 1880's truss structure mainly served streetcar traffic and was inadequate for automobiles. It was intended that after the Jerome Street Bridge opened that the older, downstream Third Avenue Bridge (1884) would also be demolished. This suspension bridge structure was also unsafe for continued automobile use. A petition signed by 5,000 people made the Allegheny County commissioners reconsider the plan. The Third Avenue Bridge was kept open for pedestrians only, but was eventually demolished in 1960.

After the city renamed Jerome Street which approached the bridge after incumbent Republican Mayor George Lysle, they proposed that the Youghiogheny crossing receive the same eponym. However, the Franklin Roosevelt administration contended that public works dollars could not be used to memorialize living officeholders. As a result, the Jerome Street designation was chosen, and it remains in place today, although it is sometimes referred to as the Lysle Boulevard Bridge.

Rehabilitation projects
A 2022 project replaced the bridge deck using polyester polymer concrete, repaired the concrete substructure, and replaced the bridge bearings. The work was completed in November 2022.

Redl-Zipf. The Redl-Zipf V-2 rocket facility (code name Schlier) located in central Austria between Vöcklabruck and Vöcklamarkt and established in September 1943 began operation for V-2 rocket motor testing after Raxwerke test equipment had been moved from Friedrichshafen.

The facility tested V-2 combustion chambers' compatibility with turbopumps since the rocket did not have a controller for reducing the turbopumping of propellant into the chamber if pressure became too high. The World War II facility used as a starting base the cellars and storage tunnels of an old brewery. Construction of the facility was under the command of SS-Obergruppenführer Hans Kammler who was responsible for Nazi civil engineering projects and its top secret weapons programs and used forced labor from the Schlier-Redl-Zipf subcamp of the Mauthausen-Gusen concentration camp. The construction added a large number of tunnels and supporting structures and included a liquid oxygen generation plant in one of the tunnels.

A large explosion on February 29, 1944, killed 14 people, destroyed several installations, and halted production of liquid oxygen at the facility for almost two months. A report to Albert Speer indicated the cause of the explosion was a liquid oxygen leak and an open carbide lamp carried by the plant foreman. Another serious explosion at 12:29 PM on August 28, 1944, killed 27 people and caused significant damage to the facility. Among the 27 casualties was Ilse Oberth (1924–1944), the youngest daughter of rocket pioneer Hermann Julius Oberth. Ilse Oberth worked at the facility as a rocket technician and had arrived four months earlier on April 28, 1944. All of those killed in the explosion were given a state funeral and are interred at the Vöcklabruck-Schöndorf cemetery. After the August 1944 explosion, liquid oxygen production at the Schlier plant stopped once again which led to the establishment of a third V-2 liquid oxygen plant (5000 tons/month) at a slate quarry at Lehesten near the Mittelwerk (turbopump/chamber compatibility testing for Mittelwerk production was also performed at the Lehesten facility).

Karl Heimberg, who had worked at Peenemünde Test Stand 7, was transferred to "Vorwerk Süd" at Redl-Zipf and then, for the period from late 1944 to early April 1945, to Lehesten (he later returned to Peenemünde with Walter Riedel III to burn design office files and participated in the post-war Operation Backfire).

The Operation Bernhard forced labor team at Sachsenhausen concentration camp for producing counterfeit British money was transferred to the Schlier-Redl-Zipf subcamp until the beginning of May 1945, when the team of prisoners was ordered to transfer to the Ebensee concentration camp.

EMD SD20. The SD20 is the product of a rebuilding program by the Illinois Central Gulf's Paducah Shops as a conversion from the EMD SD7, EMD SD24, SD24B (cabless), and EMD SD35 locomotives. The program involved rebuilding the 567 engine to 645E with 2000 horsepower rating, eliminating the turbocharger if equipped with one, upgrading the electronics to Dash 2 technology, and adding cabs to the B units. A total of 42 units were rebuilt. Original heritage of the rebuilt units was 3 Union Pacific SD7s, 4 Union Pacific SD24s, 10 Union Pacific SD24Bs, 21 Southern SD24s, and 4 Baltimore and Ohio SD35s. Many of the units to be rebuilt were purchased from Precision National. Three of the ex-Southern SD24s wore Precision reporting marks. The locomotives were rebuilt between August 1979 and December 1982. Road Numbers assigned were 2000–2041. Unit 2041 was the last Paducah rebuild.

Usage
Many SD20s are still in use with leasing companies and regional and shortline railroads. The Wisconsin and Southern Railroad and Indiana Harbor Belt are both notable second and third owners of the SD20. On January 22, 2008, the Wisconsin Southern ran its last run using an SD20, all have now been sold.
