USNS Hayes (T-AGOR-16). USNS Hayes (T-AGOR-16/T-AG-195) was a Hayes-class oceanographic research ship acquired by the United States Navy in 1971.  In 1992 she was reconfigured as an acoustics research ship and assigned to the Navy's program of acoustic noise reduction for submarines.

Built at Seattle, Washington
Hayes was built in Seattle, Washington, by Todd Shipyards, Corp., and was laid down on 12 November 1969 and launched on 2 July 1970. She was named after Dr. Harvey C. Hayes, a pioneer in underwater acoustics and the former head of the US Navy Sound Division of Naval Research Laboratory. She was delivered to the Navy 21 July 1971 and placed in service by the Military Sealift Command (MSC) as USNS Hayes (T-AGOR-16). After completing service with the MSC, she was placed into Ready Reserve 10 June 1983. In 1984 Hayes was laid up in the National Defense Reserve Fleet, James River, Fort Eustis, Virginia.

Conversion to acoustics research ship
Hayes was reacquired by the Navy during fiscal year 1986 and was converted into an Acoustic Research Ship at Tacoma Boatbuilding Company, Tacoma, Washington. MSC placed the ship back into service in 1992, this time as USNS Hayes (T-AG-195).

Hayes was equipped in 1994 with one-of-a-kind sensor arrays, including three acoustic deploy-able buoys from each of which were suspended a custom designed seven hundred channel High Frequency Baffled Cylindrical Array designed and built by the Westinghouse Oceanic Division of Annapolis, MD; and a Low Frequency Array of vertical line arrays designed and constructed by SAIC of McLean, Virginia.  Each buoy provided over 1500 acoustic channels of information that required extensive processing by two Cray IV computers also custom designed for the application.   The arrays and computer created a fully steerable sensor suit that could isolate noise sources in the submarines and assist in determining the source of excessive noise emitted by the submarine.

Submarines to be used for test and development, and to be quietened by engineers using the data from the Hayes, would pass submerged through the three buoy arrays in the deep waters off Andros Island, Bahamas.

History of operations
Hayes was assigned to underwater acoustics research for the purpose of reducing the acoustic noise of underwater submarines.  She was struck from the Naval Register in 2008 and laid up at the Philadelphia Naval Shipyard.

Note
There is no history of Hayes' operations in DANFS.

Turnbull Field. Turnbull Field was an aerodrome near Gili Gili, Papua New Guinea.

History
Built by the US Army 2nd Battalion of 43rd Engineer General Service Regiment (less Company E), during the Battle of Milne Bay during World War II with assistance from the 105th Naval Construction Battalion.  Originally known as No. 3 Strip, the airfield was renamed Turnbull Field on 14 September 1942 in honour of Royal Australian Air Force Squadron Leader Peter Turnbull, who was killed in an aircraft crash. The single runway was  long x  wide surfaced with marston matting. Taxiways and revetments extended off both sides of the runway.

The aerodrome was abandoned in February 1944 and has been disused since the end of World War II.

2008 Guangxi chemical plant explosions. A series of explosions caused by an industrial accident occurred on August 26, 2008 in Yizhou city in Guangxi province in southwest China.

The disaster occurred at a factory owned by Guangxi Guangwei Chemical Co. in the development zone of Yizhou city 

According to the state-run Xinhua News Agency, "the plant mainly produces polyvinyl acetate (PVA), which is used in adhesives, calcium carbide, and vinyl acetate monomer (VAM), which is used in paints, adhesives and coatings."

The first explosion occurred at about 6 a.m. on August 26 at an organic compound workshop inside the plant; the cause is unknown. Other explosions continued until 1 p.m. Fire spread over an area of nearly 108,000 square feet (10,000m²). The explosions caused the leak of toxic substances, including ammonia, formaldehyde, acetylene, sulfurated hydrogen and carbon monoxide.

At least 20 people were killed and at least 60 were injured; six people remained missing following the explosions. Fearing further explosions and leaks, the government evacuated 11,500 residents.

Xinhua quoted the provincial toxic substances emergency center director as saying that the explosions causes no serious air or water pollution. The director also said that dams had been erected to prevent discharge of pollutants into the nearby Long River (Longjiang).

Germanium disulfide. Germanium disulfide or Germanium(IV) sulfide is the inorganic compound with the formula GeS2. It is a white high-melting crystalline solid. The compound is a 3-dimensional polymer, in contrast to silicon disulfide, which is a one-dimensional polymer.  The Ge-S distance is 2.19 Å.

Isolation,  production, reactions
Germanium disulfide was first found in samples of argyrodite. The fact that germanium sulfide does not dissolve in aqueous acid facilitated its isolation.

Germanium disulfide is produced by treating a solution of germanium tetrachloride in a concentrated hydrochloric acid solution with  hydrogen sulfide.  It precipitates as a white solid.

It is insoluble in water, it dissolves in aqueous solutions of sodium sulfide owing to the formation of thiogermanates:

Natural occurrence
Natural GeS2 is restricted to fumaroles of some burning coal-mining waste heaps.

Württemberg AD. The Württemberg AD was a German steam locomotive built for the Royal Württemberg State Railways. It was an express train engine with a 4-4-0 wheel arrangement and was built from 1899 by the Maschinenfabrik Esslingen ('Esslingen Engineering Works'). Up to that point the railway only had increasingly elderly locomotives with a 2-4-0 configuration.

The vehicles were equipped with a two-cylinder, compound engine. The most striking feature was the large, horizontal pipe connecting the two steam domes. Ninety eight engines of this class were built by 1907; they initially had flat slide valves, but from 1903 piston valves were installed.

In 1907 two locomotives were tested with two-cylinder, superheated steam engines. This reduced the boiler overpressure to  and generated an improvement in performance of about 20%. As a result, 17 more locomotives were built to this configuration up to 1909 and were designated as Class ADh.

Both classes began to be retired in the early 1920s.

The Deutsche Reichsbahn took over 24 of the compound locomotives as DRG Class 13.16 with numbers 13 1601 to 13 1624, and 14 superheated locomotives as DRG Class 13.17 with numbers 13 1701 to 13 1714. The first ones were retired in 1928, the last in 1932.

The locomotives were equipped with Württemberg wü 2 T 10 and wü 3 T 15,5 tenders.

Fordson E83W. The Fordson E83W (also sold from 1952 under the Thames brand as Thames E83W) is a 10 cwt (half ton) light commercial vehicle that was built by Ford of Britain at the Ford Dagenham assembly plant (home of Fordson tractors) between 1938 and 1957. The van was sold in Australia as the Ford Ten-Ten, and the E83W was available in various forms around much of the world as Britain strove to export after World War II. In some countries, the 'cowl and chassis' only was imported and local bodies built.

The E83W was aimed at the small haulage, trade and merchant market, sectors in which it sold well. An estate car variant was also available. During and after World War II, many specialist variations such as mobile canteens, ice cream vans and even fire pumps were built on the E83W chassis. An estate variant was also marketed but did not find much success. Its main competitor was the Bedford HC and JC models produced by General Motors' UK commercial subsidiary.

The E83W was powered by the  Ford 10 hp side-valve engine, producing , with a 3-speed gearbox, and was heavily geared down in the rear axle. This made the Fordson much slower than the saloons, with an effective top speed of not much over . Apart from the "ten" hp engine, the E83W shares few parts with the other small Fords, which does make spares a little harder to get hold of. The front and rear axles are much heavier than the saloon and 5cwt van components, and share some parts such as bearings and other internals with the contemporary Ford V8 models (Models 62 and E71A Pilot). The headlamps were shared with the E27N tractor, for which they were an optional extra only.

Arnold Jung Lokomotivfabrik. The Arnold Jung Lokomotivfabrik (Arnold Jung Locomotive Works) was a locomotive manufacturer, in particular of Feldbahn locomotives, in Kirchen, Rheinland-Pfalz, Germany.

History  
The firm was founded on 13 February 1885 as Jung & Staimer OHG by Arnold Jung and Christian Staimer. On 3 September 1885 the first locomotive was delivered. In 1913 the company was renamed Arnold Jung Lokomotivfabrik GmbH, Jungenthal. In 1976 locomotive production was stopped in favour of other products such as machine tools, transporters, armour plating, cranes and bridgelayers.

Jung built more than 12,000 locomotives. In the 1950s it built 51 DB Class 23 2-6-2 locomotives, including in 1959, number 23 105, the last new steam locomotive supplied to the Deutsche Bundesbahn. Jung also made boilers for other uses such as steam rollers.

By the 1950s Jung was also building diesel locomotives, such as the 42 standard gauge Egyptian Republic Railways 4211 class shunters in 1953–56.

Production ceased on 30 September 1993 and the factory closed, but the firm continues to exist as Jungenthal Systemtechnik GmbH.

Preserved locomotives

There are 281 Arnold Jung steam locomotives still extant, according to the list at Steam Locomotive website.

Gallery

There is a 5025 steam machine in the "Museo Ferroviario de Santiago de Chile". This machine served in the railway that existed between the Chilean southern towns "Los Sauces" and "Capitan Pastene" (35 km). This railway was begun to be built in 1904 and in 1978 was abandoned.

TIA-607-B. Covering the grounding and bonding requirements for a building's electrical system and telecommunications cabling infrastructure, TIA-607-B is an American National Standard created by the Telecommunications Industry Association, which facilitates the design and installation of telecom grounding/bonding systems.

Grounding and bonding not only save lives by preventing electrical hazards, they also maintain a network's overall performance by ensuring that electromagnetic “noise” doesn't interfere with data transmission. Whether the telecommunications system is based on Shielded Twisted Pair (STP) or Unshielded Twisted Pair (UTP) cable, TIA-607-B requires that each and every metallic component making contact with a telecom cabling infrastructure be bonded, even if it is merely touching another metal component that is directly attached.

According to the standard, proper infrastructure bonding requires the following elements: a telecommunications main grounding busbar (TMGB), telecommunications grounding busbars (TGB), telecommunications bonding backbone (TBB), grounding equalizers (GE), and a bonding conductor for telecommunications (BCT). Among TIA-607-B's list of metallic components in need of bonding are racks, enclosures, ladders, surge protectors, cable trays, routers, switches and patch panels.

Following the bonding of telecom infrastructure components, the entire system must be bonded to the building's main ground, which is sometimes also referred to as a grounding electrode system.
