SMA SR305-230. The SMA SR305-230 is an air/oil-cooled, horizontally opposed, four-cylinder, four-stroke, diesel piston aircraft engine producing . The engine is manufactured by SMA Engines, and is currently the only product of this French company. The engine is offered as a conversion package for the Cessna 182.

Design
The SMA SR 305-230-1 is a four-cylinder, horizontally opposed turbocharged direct fuel injection diesel engine. The engine installation includes an electronic central processing unit (CPU) that continually calculates the proper fuel/air mixture. If this unit fails completely during flight, the mechanical backup position is selected and the pilot can control the fuel/air mixture as required to complete the flight.

Full-throttle operation at sea level is  of manifold pressure which is available to . Unlike some aircraft engines, which recommend the maximum power setting be used only for five minutes during the initial takeoff stage, the SR 305 can be operated indefinitely at this setting, although normal cruise is at  and economy cruise at  of manifold pressure.

The STC conversion on the Cessna 182 includes a new cowl, both to accommodate the different engine dimensions and to provide the required cooling airflow. Belly-mounted cowl flaps are still used, but less cooling airflow is directed over the cylinder barrels and more cooling airflow is directed into side-mounted oil coolers.  About one-third of the engine cooling is provided by airflow over the cylinders; the remainder is provided by engine oil. The engine's oil distribution system routes a large oil flow to hot zones in the cylinder heads and upper cylinder barrels, carrying the heat away to the oil coolers.

As of early 2008, SMA had provided over 50 conversion packages. (The installation is usually performed by other companies, not SMA.) Most of those conversions were performed in Europe, with less than a dozen having been performed in North America.

The cost of conversion may be justified in areas where aviation gasoline costs significantly more than jet fuel, and by the fact that the diesel fuel flow at cruise is about 10 gallons (38 litres) per hour, compared to about 13.5 gallons (51 litres) per hour with the original engine.

SMA expects 90 engines to be delivered in 2014, and is working on six-cylinder version called the SR460 which will have an output of .

Applications
 SMA SR305-230: Cessna 182 (STC conversion)
 SMA SR305-260E: Diamond DA50
 SMA SR305-230 ATLS GS-301 Batoor

In July 2012, Cessna announced it would offer the Cessna 182 with this engine as a factory option, with deliveries expected by the second quarter of 2013. Cessna also stated at that time that the SMA engine would eventually replace the current avgas engine. This plan was abandoned and in 2023 the Cessna 182 was still being sold only with the Lycoming IO-540-AB1A5 gasoline engine.

ZF Wind Power Antwerpen. ZF Wind Power Antwerpen is a business unit of ZF Friedrichshafen, that designs, manufactures and supplies wind turbine gearboxes.

History

The company was founded in 1923 in Antwerp under the name La Mécanique Générale (LMG). The company soon focused on the manufacturing of specialized transmission units, under engineer David Hansen. In 1939 the company moved to Edegem, to ensure there was sufficient room for future expansions. In 1950, Hansen founded the subsidiary Machinery & Gear Hansen (MGH). LMG and MGH merged in 1966, and in 1972 it was renamed to Hansen Transmissions International (HTI). From 1979, the company increasingly focused on the supply of gearboxes to the growing wind energy generation sector.

After a series of takeovers in the period after 1966, Hansen Transmissions was acquired on March 17, 2006, by Suzlon Energy through its subsidiary, AE-Rotor Holding BV, for €465 million in cash from Allianz Capital Partners and Apax Partners.  The transaction was the second largest foreign acquisition by an Indian company to date. The rationale of the acquisition was to secure access to the crucial supply of gearboxes for the wind turbine manufacturer. Hansen hoped to benefit from the regional knowledge and expertise of Suzlon Energy in its expansions in India.

Yet Suzlon subsequently struggled with a high debt burden. In December 2007, Hansen transmission was listed on the London Stock exchange. Suzlon continued to sell pieces of Hansen Transmissions in the years that followed, most notably in November 2009, selling a 35.22% share to repay an outstanding acquisition loan facility. The remaining share of Suzlon in Hansen was 26.1%, making it the largest shareholder.

In September 2011 it was acquired by ZF Friedrichshafen AG, and in December 2011 the company was renamed to ZF Wind Power Antwerpen (Belgium). In December 2015, ZF took over the wind turbine gearbox segment of Bosch Rexroth.

ZF Wind Power Antwerpen currently operates six manufacturing plants with an annual output capacity of approximately 16,000 MW. The company manufactures in Belgium, India, Germany, the US and China.

Today ZF is one of the leading providers of innovative wind power gear boxes with a global market share of ~25%.

Carl Geigy. Carl Geigy (24 June 1860, in Steinen, Baden-Württemberg – 3 January 1943, in Münchenstein) (also Karl) was a famous Swiss philanthropist.

Biography
Geigy was son of Carl (1834–1862), Basler Entrepreneur, and Margaretha Emilie Burckhardt (1838–1911). His grandfather was Karl Geigy (1798–1861) President of the Swiss Centralbahngesellschaft.

Carl Geigy grew up in Basel, Switzerland, and visited the Gymnasium and the vocational school in Basel. He served his apprenticeship as mechanical engineer in Lausanne. He  continued his professional training in a weaving factory in Bradford and in a spinning mill in Oldham. Here Carl Geigy became acquainted with the social problems of the working class.

Following a journey around the world he returned to Switzerland in 1887. He was co-founder of the engineering association in Basel. From 1904 onwards he withdrew from his professional career.

Carl Geigy lived in the Bruckgut estate in Münchenstein and built the farm house and barn there in 1888. He married Julia Elisabeth Burckhardt (1872–1949) from Basel in 1897. They had four children, Eduard (1899–1941), Julie (1900–1966), Jenny (1903–1990) and Karl Felix (1904–1977).
 
Following his withdrawal from his occupation, he devoted his time to the social humanitarian and religious tasks. He dedicated himself to the building of the children's hospital in Basel. Carl Geigy became famous as philanthropist and was a father figure in Münchenstein, where he was awarded the honorary citizenship in 1937.

E. & B. Holmes Machinery Company Building. E. & B. Holmes Machinery Company Building, also known as The Cooperage, is a historic factory building located at Buffalo in Erie County, New York.  It is a roughly rectangular brick building composed of three primary sections of four-, three-, and two-stories, which encircle a central courtyard.  The three sections are the Mill Building (ca. 1870), Forge Building (ca. 1910-1912), and Pattern Building (1913).  The E. & B. Holmes Machinery Company revolutionized the barrel making industry by patenting the design and manufacturing of machinery used for mass-producing barrels.  The company operated from 1840 until 2002.

Plans announced in January 2010 are for the complex to be converted to "live and work" apartments and commercial space by Newark Niagara LLC in partnership with Clinton Brown Company Architecture. More information about the project can be found at River Lofts Buffalo.

It was listed on the National Register of Historic Places in 2009.

Floatstone. Floatstone is a type of carbonate rock.

The original Dunham classification (Dunham, 1962) of limestones did not consider the separate classification of coarse grained carbonate lithologies. In an attempt to rectify this, Embry & Klovan (1971) introduced the terms rudstone (grain supported) and floatstone (matrix supported) for coarse-grained allochthonous limestones. This definition of a floatstone was most recently clarified as "a carbonate-dominated rock where more than 10% of the volume is grains larger than 2 mm and the fabric is supported by the component that is 2 mm and smaller".

Institut für Weltraumforschung (Space Research Institute). The Institut für Weltraumforschung (IWF - Space Research Institute) is one of the biggest institutes of the Austrian Academy of Sciences (Österreichische Akademie der Wissenschaften - OeAW) and is located in Graz. Established in 1970, it has been studying the physics of space plasmas and the atmospheres of planets inside and outside the Solar System for more than 50 years. With about 100 employees from twenty nations, it is located in the Victor Franz Hess Research Center of OeAW in the south of Graz. At the Lustbühel Observatory it operates a satellite laser ranging station, which is one of the best in the world.

Participation in space missions 

IWF is the only institute in Austria that develops and builds space-qualified instruments on a large scale. The data returned by them are scientifically analysed and physically interpreted at the institute. IWF's core engineering expertise is in building magnetometers and on-board computers, as well as in laser ranging to satellites and space debris. In terms of science, IWF concentrates on dynamic processes in space plasma physics and on the upper atmospheres of planets and exoplanets - i.e. planets outside our solar system.

Space has been explored with the help of satellites for more than 60 years and still poses many puzzles. Since the beginning of the 1980s, IWF has contributed/is contributing to more than 40 international space missions with over 100 scientific instruments. The institute is currently involved in 23 projects led by the European Space Agency (ESA), NASA or national space agencies in Japan, Russia, China, and South Korea. The missions cover fleets of satellites in near-Earth space (Cluster, MMS, THEMIS), the observation of the Sun (STEREO, Solar Orbiter) and the exploration of planets such as Mercury (BepiColombo), Jupiter (Juno, JUICE) and extrasolar planets (CHEOPS). From building the instruments to analyzing their data, these projects last 10-30 years. While IWF has already "harvested" the data from past missions (Cassini/Huygens, Rosetta) and the scientists are eagerly analyzing the data from the current missions, in the laboratory the sophisticated sensors and instruments for future missions are being developed.

Historical RC plane manufacturers

Many notable individuals in the 1960s through the 1990s and beyond created the landscape of modern RC modeling.  These included many starting their own companies.  The families of many of these individuals lost interest in continuing these businesses.  The incoming supply of ARF planes from overseas made it hard to sell kits requiring assembly.

Project Z (bomber project). Project Z (also called the "Z Bombers Project") was a military project of the Empire of Japan, similar to the Nazi German Amerikabomber project, to design an intercontinental bomber capable of reaching North America.

The planned aircraft
The Project Z aircraft was to have six  engines; the Nakajima Aircraft Company quickly began developing engines, proposing twinned Nakajima Ha-44 engines (the most powerful aircraft engine available in Japan at the time).

Designs were presented to the Imperial Japanese Army, including the Nakajima G10N, Kawasaki Ki-91, and Nakajima G5N. None, save for the G5N, developed beyond prototypes or wind tunnel models. Late in the war, Project Z and other heavy bomber projects were cancelled.
