Brian Waugh. Brian Kynaston Waugh (1922–1984) was a notable New Zealand aircraft engineer, military and commercial aviator, airline operator, meteorologist. He was born in Shrewsbury, Shropshire, England in 1922.

Early years 
Brian Kynaston Waugh was born in Shrewsbury, Shropshire, England, on 26 September 1922. He was the second of two sons of Helen Elizabeth Caudle and her husband, Walter Waugh, an electrical engineer. He developed an early fascination with aviation after his father became a foreman on the construction of an RAF station in Shropshire.

Second World War 
In August 1938, he joined the RAF’s aircraft apprentice training scheme, and in 1941 he was posted to South Africa. While there, he transferred to pilot training, gaining his wings on 24 September 1943. In the latter part of the war, he served with No.75 (NZ) Squadron on Avro Lancasters. Night raids to Germany included Bremen, the Leuna Oil Refinery at Merseburg, the Howaldt Works, and the inner dockyard at Kiel where the German pocket battleship Admiral Scheer was capsized. Continuing Lancaster flying, he dropped food to the starving Dutch at The Hague in Operation Manna, ferried Belgian refugees home, repatriated Allied Prisoners of War, and flew long scenic (Baedeker) flights over Germany, Belgium and Denmark. At the end of hostilities, Waugh continued in RAF service with transport squadrons in England, Europe, and in South East Asia, based in Singapore. He left the RAF after 10 years’ service in 1948.

Post-war Flying 
He gained his civil pilot licence, instrument rating and engineering licence in categories A (airframes), C (engines) and X (compasses), including type ratings for de Havilland DH89 Rapide aircraft and their Gipsy engines. He then flew for post-war small British airlines. In 1954, Waugh immigrated to New Zealand to fly DH89s for South Island Airways on pioneering scheduled routes. After service with Trans Island Airways, he was appointed in 1959 Chief Pilot and Chief Engineer for West Coast Airways at Hokitika, flying the historic South Westland Air Service, New Zealand’s first licensed scheduled air service. He became well-known on the West Coast with air ambulance work, particularly before the Haast highways was opened in 1965. On 15 April 1967, he was seriously injured in the forced landing of DH89 ZK-AKT in Queenstown’s Shotover River, due to engine failure. He subsequently retired from flying and served in the Meteorological Department at Hokitika and Gisborne. In the 1980s he wrote his aviation autobiography which was published in 1991: ‘Turbulent Years – A Commercial Pilots’ Story’. The book gives his insights into New Zealand provincial flying in the 1950s and 1960s.

Saladin box. A Saladin box is an instrument used for malting barley. It consists of a large rectangular container about 50 meters in length, and a set of vertical screws attached to a crossbar. The crossbar moves horizontally across the length of the container while the motion of the screws raises the barley from the bottom to the top. Combined with mechanical air flow across the barley for cooling, this allows for beds of barley between  and  deep to be turned over two or three times a day. The screws are moved and turned by a system of pulleys and belts.

The Saladin box was invented by French engineer Charles Saladin in the late 1800s to overcome the problem where the roots of the malting barley would become entangled if not regularly turned by hand, forming large mats unusable for further processing, as encountered in the earlier system that used artificial air flow to cool the barley in deeper beds designed by Galland.

The first U.S. brewery to use the Saladin system was John A. Huck Brewery in Chicago, Illinois.

Modern malting devices use a similar systems of screws as those invented by Saladin, but use ribbon screws rather than closed screws, perforated floors for aeration and cooling, and circular vessels instead of rectangular boxes

In Scotland there's only one distillery that still uses the Saladin box: Tamdhu. This distillery uses two such boxes to fill the kiln, and two steeps to fill the box. Tamdhu was, incidentally, also one of the first Scottish distilleries to install a Saladin box.

Pitcairn PA-4 Fleetwing II. The  Pitcairn PA-4 Fleetwing II, also called the Pitcairn Fleetwing DeLuxe, and the Pitcairn PA-4 Fleetwing is a commercial mail hauling and passenger biplane.

Design and development
Ten PA-4s were built before it was re-engined with the Wright J-5 Whirlwind as the Pitcairn PA-5 to fly on the CAM-19 mail routes.

The Fleetwing II is a conventional landing gear equipped biplane with strut-braced tail surfaces. The fuselage is welded steel-tube construction with aircraft fabric covering. The cowling is formed from two pieces. The wire wheels were streamlined with laced-on discs.

Operational history
Six Fleetwings were sold directly to Pitcairn Aviation. In 1928, the Fleetwing II The City of Reading participated in the Transcontinental Air Race. It was sold to Reading Airways after the race and later used in stunt flying around Cumberland, Maryland with the signature "Flying through a train tunnel" illusion.

The sole remaining Fleetwing II was rebuilt over the course of seven years by Harold Armstrong from drawings supplied by Steve Pitcairn (1925-2008), son of company founder Harold Frederick Pitcairn (1897-1960). The aircraft won Grand Champion Antique at the 1991 EAA AirVenture Oshkosh airshow.   Armstrong's Fleetwing was seriously damaged in an accident on September 9, 2012.

List of proposed space telescopes. This list contains proposals for space telescopes, space-based (situated in space) astronomical observatories.  It is a list of past and present space observatory plans, concepts, and proposals.  For observatories in orbit, see list of space telescopes.  Unlike that list, this one includes concepts and proposals that are unlikely ever to be launched, as they may have been cancelled or were only proposals.

Space observatories under development

Merged, cancelled, or superseded space observatories

Additional examples and non-space telescopes 
For launch in the 2030s, NASA is evaluating four possible designs:  the Origins Space Telescope, Lynx X-ray Observatory, Habitable Exoplanets Observatory (HabEx), and Large UV Optical Infrared Surveyor (LUVOIR).

Balloon-borne telescopes have been in use since the 1950s. A 20–30 meter balloon telescope has been suggested. The balloon would be transparent on one side, and have a circular reflecting mirror on the other side. There are two main designs using this principle.

Prehnitene. Prehnitene or 1,2,3,4-tetramethylbenzene is an organic compound with the formula C6H2(CH3)4, classified as an aromatic hydrocarbon. It is a flammable colorless liquid which is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar. Prehnitene is one of three isomers of  tetramethylbenzene, the other two being isodurene (1,2,3,5-tetramethylbenzene) and durene (1,2,4,5-tetramethylbenzene). It is a relatively easily oxidized benzene derivative, with E1/2 of 2.0 V vs NHE.

Production 
Industrially, prehnitene can be isolated from the reformed fraction of oil refineries. It may also be produced by methylation of toluene, xylenes and the trimethylbenzenes hemimellitene and pseudocumene.
