Holleville RH.1 Bambi. The Holleville RH.1 Bambi is a French-built light sporting aircraft of the 1950s.

Development and design
The RH.1 Bambi was designed and built by Monsieur Roger Holleville and flown for the first time in 1953. It is a side-by-side two-seat aircraft and was unusual at the time to be among self-build types to make extensive use of synthetic resins and sandwich construction. It was originally intended to make construction plans available to clubs and groups. However, the rather sophisticated design motivated against the acceptance of the Bambi by amateur constructors.

The Bambi is basically of wooden construction and the exceptional cleanliness of the overall design results in an outstanding performance on a 65 h.p. engine.

The aircraft has a low-wing layout and a fixed tail-wheel undercarriage.

Operational history
The Bambi was initially operated by its designer from Guyancourt airfield to the west of Paris. By 1964 it was owned by Monsieur Gerard Chaplain and based at St Dizier.

It has visited the United Kingdom to attend light aircraft rallies including at Biggin Hill airport in Kent in 1967. The Bambi is preserved in airworthy condition in the Musee Regional de l'Air at Angers Aerodrome, 20 km north east of the town.

Amund Ringnes (brewery owner, 1905). Amund Ringnes (24 June 1905 – 1980) was a Norwegian brewery owner.

He was born in Oslo to Andreas Ringnes (1874–1928) and Ragna Jensen (1876–1944). He was the grandson of brewery owner and patron Amund Ringnes (1840–1907). He married Laura Kristine Falkenberg in 1928.

He started studying chemistry in 1923, and graduated in chemical engineering from the Norwegian Institute of Technology in 1927. He took training as a brewery master in Copenhagen, finished in 1929 and was employed by Ringnes brewery in the same year. After a period as a chemist, he became a manager in 1935 and chief executive officer in 1945. He was also a member of the board.

He chaired the employers' association Bryggerienes Arbeidsgiverforening from 1952 to 1957, was a central board member of the Norwegian Employers' Confederation 1952 to 1957 and the Federation of Norwegian Industries from 1957 to 1961. He was a board member of Nora Fabrikker since 1945, Vel-Vask from 1946 to 1956, Tønsberg Bryggeri since 1962, Farris since 1963, Christiania Bank og Kreditkasse since 1969 (formerly a supervisory council member) and Forsikringsaktieselskabet Norden since 1957 (chair since 1968, formerly a supervisory council member from 1945 to 1957). He was a member of the Norway Travel Association, and in science, he was a member of the European Brewery Convention from 1947, and of the NTNF council from 1955 to 1963. He was decorated as a Knight of the Order of the Dannebrog.

Addyman STG. The Addyman STG was a single seat primary glider, amateur designed and built in the United Kingdom in the mid-1930s.

Design
Erik T. W. Addyman designed and built his STG single seat primary glider for low cost basic training.  As such, it was a simple, wooden, aerodynamically unrefined aircraft with a relatively low aspect ratio wing, a cockpit nacelle under it and a flat open truss girder fuselage aft.  The unswept wing had parallel chord with blunt tips and was built around two spars. There were no flaps or airbrakes.  Above the wing landing wires ran from about mid-span on each wing from the spars to the top of a centrally mounted inverted V-strut; below, similarly arranged flying wires ran to the lower nacelle longerons.

Attached immediately behind the single open cockpit headrest at the forward wing spar, the nacelle extended rearwards only to the wing trailing edge, suspended from an inverted V pair of struts to the rear spar. A landing skid extended over most of the length of the nacelle. Aft of the nacelle, the fuselage was an uncovered converging Warren girder structure carrying the tail surfaces and braced laterally by wires to the mid-span wing points.  The fin was very small but carried an almost rectangular rudder which extended to the fuselage keel via a cut-out in the elevators.  The tailplane was straight tapered, with a swept leading edge.  A wire tail bumper completed the undercarriage.

The STG was built at Harrogate and flew for the first time in June 1934.

Operational history
It seems that two STGs were built.  One of them was originally based at Wigan, the other at Harrogate. Addyman was the Honorary Secretary of The Aircraft Club, Harrogate; a letter from him to Flight in July 1942 says that one STG was there, "overhauled", and another was three-quarters built, though the former was unable to fly because of a Government ban on glider use at that point of the War. The fate of the partially built STG is not known.  There were plans to build another after World War II but construction probably did not start.  The two completed aircraft survive in store in 2010.

Another STG was begun, intended for powered flight using an Anzani engine. Parts of this machine, which has become known as the Addyman UL (UltraLight), also survive in store.

Crystalate. Crystalate is an early plastic, a formulation of nitrocellulose, camphor, and alcohol invented in the late 19th century and patented by American inventor George Henry Burt. It is best known as a material for gramophone records produced in the UK by Crystalate Manufacturing Company (although Burt's own US-based Globe Record Company also manufactured Crystalate records), and for moulded billiards, pool and snooker balls, as produced by the Endolithic Company (UK, later the Composition Billiard Ball Company).

Crystalate was based on Bonzoline, a plastic produced by John Wesley Hyatt's US-based Albany Billiard Ball Company. Burt, a former Albany employee, began manufacturing what was essentially Bonzoline in the UK in 1900 as crystalate with Percy Warnford-Davis, under the Endolithic name. While Crystalate as a plastic material is obsolete and no longer manufactured. Like Celluloid and Bakelite it is commonly encountered by collectors of vintage and antique goods, because many products were made using the substance. The plastic was even mandated in the UK for making billiard balls by the Billiards Association and Control Council in 1926.

Super Crystalate is a brand name for a composition material, a cast rather than moulded resin, first produced by Composition Billiard Ball in 1972 as a replacement for Crystalate.  Super Crystalate is no longer manufactured but it continues as a trade name on the Aramith Super Crystalate snooker ball sets that are made from phenolic resin.

Union Carriage & Wagon. Union Carriage & Wagon (UCW) is a rolling stock manufacturer in South Africa. It presently functions as one of the two South African subsidiaries of the French rolling stock manufacturer Alstom.

History

Union Carriage & Wagon was established in 1957. Initial shareholders were Commonwealth Engineering (51%), Budd Company (25%) and Leyland Motors (12%). By 1965, Budd and Metro Cammell Weymann held a combined 41% shareholding which they sold to Anglo American plc and General Mining. In December 1969, Commonwealth Engineering reduced its shareholding to 42% with the other two shareholders each owning 29%.

Having initially built carriages, in 1964, UCW delivered its first electrical locomotives to the South African Railways, the South African Class 5E1, Series 2. The Class 5E1 was also the first electrical locomotive to be produced in quantity in South Africa. 

In 1974, UCW entered the international market with orders from Angola and Zambia. In 1976, UCW received its first Asian order for twenty Type E100 electric locomotives for Taiwan Railways Administration (TRA), based on a GEC design. In addition, the TRA E1000 push-pull trainsets were also manufactured jointly by UCW, GEC-Alsthom, Tang Eng Iron Works of Taiwan and Hyundai Rotem of South Korea. In 1993, UCW formed a joint venture with Siemens Mobility, SGP Verkehrstechnik and China Steel Corporation to manufacture 216 cars (36 6-car sets) of C321 metro cars for the Bannan Line of Taipei Metro, the first of which entered service in 1999.

Rolling stock for Gautrain is assembled at the UCW plant in Nigel under a partnership agreement between Bombardier Transportation and UCW.

In 1987, Commonwealth Engineering Parent company Australian National Industries sold its shareholding to Malbak Limited. In October 1996, the business was sold to Murray & Roberts. In February 2013, UCW was purchased by Commuter Transport Engineering. In April 2016, Alstom acquired 51% shares and renamed the company Alstom Ubunye.

Yan Xiao. Yan Xiao is an engineer and Professor of Civil Engineering at USC.  He is best known for inventing structural uses for bamboo.

He describes his research interests as "seismic analysis and design of structures; experimental analysis of structures, components and materials, and implementation of new materials into structural design and retrofit."

In 2006, Xiao developed a bamboo derived material known as GluBam that was strong enough to be used for beams and trusses.  He was able to build a 33-foot heavy use bridge, capable of supporting 8 tons, in Leiyang, Hunan, using the material.  A principal advantage of GluBam is construction of large structures such as a bridge doesn't require heavy machinery.  The bridge was assembled in a quick 10 days. In addition to the machinery and speed requirements, the GluBam beams cost 20 percent as what imported lumber costs. Rural China also has a constantly replenishing supply of bamboo.

While on sabbatical in 2008, he created quick to build homes made from the material to be used as a rapid housing solution following the 2008 Sichuan earthquake which had left many homeless.

Xiao was featured in Popular Science's Top 100 Innovations of 2008 for "Glubam Construction: The Sustainable Bridge."

El Qanater El Khayreya. El Qanater El Khayreya (  , "the Benevolent Bridges") is a city and a markaz in Qalyubia Governorate, Egypt. It is the location of the Delta Barrages, the first modern irrigation structure across the Nile, located at the apex of the Nile Delta.  In the mid 1850s, when Viceroy Sa'id Pasha took over project construction, he ordered a silver medal to be struck to mark the occasion. He then ordered the construction of a town near the incomplete barrage. Again the project would be bogged down due to financial problems; the original barrages were initially completed in 1862. A new barrage structure was built slightly downstream in 1939. The name of the city is a reference to the structure and the river crossing it.

Toshima Incineration Plant. The  is a waste treatment plant located in Kami-ikebukuro, Toshima, Tokyo, Japan. It covers an area of 12,000 square meters and has two incineration units with a combined capacity of 400 tons of waste per day.

The plant was constructed with a large fitness center in order to appease area residents who may have otherwise opposed its construction. The center's swimming pool is heated from burning garbage while electricity is supplied from a steam-driven turbine. The plant outputs 7,800 kW of electricity, enough to supply 20,000 homes.

The plant's smokestack, at 210 meters in height, is the tallest industrial chimney in the special wards of Tokyo and was constructed in order for exhaust from the plant to clear the nearby 239-meter Sunshine 60 building.

Air Cavalry. Air Cavalry is a flight simulation video game developed by Synergistic Software. It was released by Cybersoft and GameTek for the Super NES in 1995.

Gameplay 

In the game, players control an advanced helicopter gunship. Flying above multiple types of terrain, players have to complete a number of objectives using different types of helicopters with different uses for each. Players can select from three theatres of operations with six or more objectives that increase in difficulty. Players can also practice in the training mission.

Reception 

Air Cavalry received generally mixed reviews. The four reviewers of Electronic Gaming Monthly commented that the low supply of ammunition and the unfailing accuracy of enemy fire make the game unpleasantly difficult, and that the Mode 7 sequences look poor. They nonetheless assessed the game as "decent", and said that enthusiasts of military games would find it very appealing.

GamePro, in contrast, praised the Mode 7 sequences and remarked that "Easy targeting and non-moving enemies makes this a better game for rookies than veterans." While they criticized the slow-moving helicopter and simplistic gameplay compared to the Strike series, they concluded that "if you're looking for a solid shooter, Air Cavalry comes to the rescue." Next Generation reviewed the game, and stated that "Success is as much of luck as skill, which makes it frustrating as well as overly repetitive."

Pole piece. A pole piece is a structure composed of material of high magnetic permeability that serves to direct the magnetic field produced by a magnet. A pole piece attaches to and in a sense extends a pole of the magnet, hence the name.

Pole pieces are used with both permanent magnets and electromagnets. In the case of an electromagnet, the pole piece or pieces simply extend the magnetic core and can even be regarded as part of it, particularly if they are made of the same material. In the case of a permanent magnet, the distinction between the magnet itself and the pole piece or pieces is more clear cut.

Materials

The traditional material for pole pieces was soft iron. While still often used with permanent magnets, soft iron suffers from eddy currents which make it less suitable for use with electromagnets, and particularly inefficient when the magnet is excited by alternating current.

Shapes and forms

Pole pieces take many shapes and forms depending on the application.

A traditional dynamic loudspeaker has a distinctive annular magnet and pole piece structure which serves to concentrate the magnetic flux on the voice coil. The central, cylindrical pole piece surrounded by the voice coil is normally referred to as the pole piece. A second pole piece in turn surrounds the voice coil.

A moving coil meter has a different and equally distinctive structure.

A magnet keeper is a specialised pole piece used to temporarily connect the poles of a permanent magnet, to help to preserve the magnetism, and for safety in the case of large and powerful magnets.

Another specialised pole piece is the armature of an electromechanical solenoid, which produces work by being attracted by an electromagnet when the magnet is actuated.

An electron lens contains two specialised pole pieces used to guide the electromagnetic field lines of the wire coils of the  permanent magnet, these field lines guides the spiral of electrons. In the objective electron lens an upper annular polepiece surrounds the column and a lower planar polepiece with a 'pinhole' on the optic axis is closest to (adjacent) the object (specimen)
