120 film

120 is a popular film format for still photography introduced by Kodak for their Brownie No. 2 in 1901. It was originally intended for amateur photography but was later superseded in this role by 135 film. 120 film and its close relative, 220 film, survive to this day as the only medium format films that are readily available to both professionals and amateur enthusiasts. As of December 2018 all production of 220 film has stopped/paused worldwide. The only remaining stocks are from the last Fujifilm production run (2018) and they are mostly found in Japan.

600 (number)

600 (six hundred) is the natural number following 599 and preceding 601.


Contax (sometimes stylised as CONTAX) began as a camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras.

EMD 567

The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8 1⁄2 in (216 mm), a stroke of 10 in (254 mm) and a displacement of 567 cu in (9.29 L) per cylinder. Like the 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke engine.

EMD's chief competitor, GE, now makes EMD-compatible replacement parts.

EMD 645

The EMD 645 family of diesel engines was designed and manufactured by the Electro-Motive Division of General Motors. While the 645 series was intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex division.

The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. First introduced in 1965, the EMD 645 series remained in production on a by-request basis long after it was replaced by the 710, and most 645 service parts are still in production. The EMD 645 engine series is currently supported by Electro-Motive Diesel, Inc., which purchased the assets of the Electro-Motive Division from General Motors in 2005.

In 1951, E. W. Kettering wrote a paper for the ASME entitled, History and Development of the 567 Series General Motors Locomotive Engine, which goes into great detail about the technical obstacles that were encountered during the development of the 567 engine. These same considerations apply to the 645 and 710, as these engines were a logical extension of the 567C, by applying a cylinder bore increase, 645, and a cylinder bore increase and a stroke increase, 710, to achieve a greater power output, without changing the external size of the engines, or their weight, thereby achieving significant improvements in horsepower per unit volume and horsepower per unit weight.


The Electro-Motive Division GT22HW-2 is a custom designed EMD A1A-A1A diesel-electric locomotive built by Đuro Đaković for Yugoslavia. Mainly used for passenger service, the reliability of these locomotives made this model a success even after the breakup of Yugoslavia. Designated as the Series 645 in the Yugoslav Railways, these locomotives were later known as the Series 2044 in the Croatian Railways after 1991. Thirty four examples (645.001 - 645.034), of this model were built between February 1981 to August 1984 and are noted with different formats of lettering due to the various ethnicities existing in Yugoslavia at the time.

.033 - .034 are lettered JUGOSLOVENSKE ŽELEZNICE - HEKURUDHAT JUGOSLLAVE (Serbian/Albanian)Due to the locomotive's unique designation, the model breaks down into several indications:

Although the locomotives are equipped with A1A-A1A running gear, no official designation was present until 1993 due to low production.

Eurocopter UH-72 Lakota

The Eurocopter (now Airbus Helicopters) UH-72 Lakota is a twin-engine helicopter with a single, four-bladed main rotor. The UH-72 is a militarized version of the Eurocopter EC145 and was built by American Eurocopter (now Airbus Helicopters, Inc.), a division of Airbus Group, Inc. Initially marketed as the UH-145, the helicopter was selected as the winner of the United States Army's Light Utility Helicopter (LUH) program on 30 June 2006. In October 2006, American Eurocopter was awarded a production contract for 345 aircraft to replace aging UH-1H/V and OH-58A/C helicopters in the US Army and Army National Guard fleets. It performs logistics and support missions within the US and the National Guard for homeland security, disaster response missions, and medical evacuations.

GWR 645 Class

The GWR 645 Class was a class of 0-6-0 saddle tank locomotives designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence they were saddle tank versions of his GWR 633 Class of 1871. From 1878 a further 72 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start.

German submarine U-645

Type 645 oceanographic research ship

Type 645 oceanographic research ship is an oceanographic ship developed by China for the People's Liberation Army Navy (PLAN) and other Chinese civilian establishments. A total of three were completed, with one in PLAN and the rest in civilian service.

Type 645 was an experimental program of the Fourth five-year plan of China and designed by the 2nd Directorate of 708th Institute of China State Shipbuilding Corporation, which is also more commonly known as China Shipbuilding and Oceanic Engineering Design Academy (中国船舶及海洋工程设计研究) nowadays. Construction begun in October 1977 and the ship was launched in October 1978, entering service with PLAN in December 1978. There are a total of twelve laboratories on board totaling 257 square meters. Deployment proved that the design was successful, and two more units were built for civilian use, named as Xiangyanghong (向阳红, meaning facing the sun in red in Chinese) 14 and Xiangyanghong 16 respectively. However, on May 2, 1993, Xiangyanghong 16 was rammed and sunk by a Cypriot cargo ship more than nine time of its size (38000 ton) in East China Sea, with lost of three crew members. The hull of Type 645 is used for Type 813 spy ship. The name of the unit in PLAN service is Nan-Diao (南调) 350, meaning South Investigate 350. In 2006, the ship went through an 11-month-long refit to be converted by Shanghai Lifeng Shipyard (上海立丰船厂) of China Shipping Group at Shanghai as the mother ship of Jiaolong (submersible). After conversion, the name of the ship reverted to its original name Xiangyanghong 9 (向阳红, meaning Facing the Sun in Red). Some oceanographic research capability is retained after the conversion in that three laboratories were retained on board. The homeport of Xiangyanghong 9 is in Qingdao. Two additional ships, Xiangyanghong 14 and Xiangyanghong 16 were also built but both went to civilian service, and latter sunk on May 2, 1993 after being hit by a 38000-ton Cypriot LNG carrier near Jeju Island.
