Blida Airport. Blida Airport is an airport in Blida, Algeria . It undertook a repavement project in 2012.

On 8 November 1942, during World War II, the airport was taken by the 11th Infantry Brigade, British Army.  The event was part of the Operation Torch of the North African Campaign. Shortly afterwards, Lieutenant B.H.C. Nation, RN, leader of a flight of Grumman Martlets from HMS Victorious, saw white handkerchiefs fluttering on the ground and landed on the airfield.  He accepted a written agreement from the French Air Commander that Allied aircraft might land. No. 326 Wing RAF began arriving by 11 November 1942 and soon its four squadrons of Bristol Bisleys were bombing Axis airfields by night. 

On 6 December 1942, the 97th Bomb Group's 414th Bomb Squadron Commanding Officer flew from Tafaraoui Airfield at Oran, Algeria to certify the preparation of the "Blida Airfield" ready to receive two 97th Bomb Group Squadrons, the 342nd and the 414th.  On 12 December 1942, the 414th Bomb Squadron Commander flew back to Tafaraoui Airfield at Oran, Algeria.  The next day, the 342nd and the 414th Bomb Squadrons flew to "Blida Airfield" and prepared for its next day's bombing mission.  On 14 December 1942, all four Bomb Squadrons from the 97th Bomb Group departed their respective bases and bombed the Tunis docks in Tunisia and returned to new their new base at Biskra, Algeria.

Carl Louis Schwendler. Carl Louis Schwendler (1838–1882) was a German electrician and one of the first proponents of the tungsten based incandescent light bulb. He also published an influential textbook on telegraphs, and worked in British India at a senior post in the Telegraph Department. He was involved in setting up telegraphic communication between Agra and Calcutta solving problems in transmission of submerged cables. He was commissioned by the Railways to perform a feasibility study of lighting Indian Railways stations by electric lamp.

Schwendler was a member of the Asiatic Society of Bengal. In 1867 a zoo was proposed by Joseph Fayrer and the idea was again raised by Schwendler in 1873. He helped in the setting up of this garden and offered his small menagerie (prior to his leaving India) to create the nucleus of the Alipore Zoological Gardens in Kolkata. The Zoological Gardens were formally inaugurated  on 1 January 1876 by the Prince of Wales (King Edward VII) and opened to the public in May with Schwendler as its first superintendent assisted by Ram Brahma Sanyal. This zoo became in 1875 the home of Robert Clive's tortoise, Adwaita, thought to be the longest-living animal in the world when he died in 2006 at an estimated of age 255.  A memorial to Schwendler was erected at the zoo premises in 1883.

Amédée Bollée. Amédée-Ernest Bollée (11 January 1844 – 20 January 1917) was a French bellfounder and inventor who specialized in steam cars. He is notable for developing the earliest known form of the independent suspension. After 1867 he was known as "Amédée père" to distinguish him from his similarly named son, Amédée-Ernest-Marie Bollée (1867–1926).

Biography
Bollée was the eldest son of Ernest-Sylvain Bollée, a bellfounder and inventor who moved to Le Mans in 1842. He became seriously ill in the 1860s and was obliged to delegate the day-to-day running of his businesses to his three sons. Amédée-Ernest was given charge of the bell foundry, while Ernest-Jules (1846–1922) supervised the hydraulic ram business and the youngest son, Auguste-Sylvain Bollée (1847–1906) assumed control of the Éolienne Bollée wind-turbine factory.

Steam vehicles

L'Obéissante

Amédée père manufactured his first steam vehicle L'Obéissante (The Obedient) in 1873 and made the first road trip between Paris and Le Mans in 18 hours. The L'Obéissante carried 12 passengers and had a cruising speed of  and a top speed of . It was driven by two V twin steam engines, one for each rear wheel. Front wheels were cushioned on the sliding pillar suspension which became the first ever independent front suspension. The original vehicle is preserved in the collection of the Conservatoire National des Arts et Métiers in Paris.

La Mancelle

In 1878 Amédée père designed La Mancelle, which is regarded as the first automobile to be put into series production, 50 being manufactured in all. It possessed such (for the period) advanced features as rear-wheel drive (via shaft to the differential and then via chain to the rear wheels) and independent suspension on all four wheels. The original vehicle is preserved in the collection of the Musée de l'Automobile de la Sarthe.

La Marie-Anne

The public demonstrations of L'Obeissante and La Mancelle had secured orders for the Bollée factory, and Amédée père accepted an order for a road train which was completed in 1879. Developing , La Marie-Anne had a three speed gearbox and was capable of towing  on a 6% slope.

La Nouvelle

Amédée père had derived from La Mancelle different vehicles that he delivered in a variety of styles of bodywork such as: limousine, coach, omnibus etc. The La Nouvelle was from this series and was completed in 1880. The rear of the vehicle was designed to receive the piston engine, this time rejected near the boiler in order to enlarge the passenger cabin.

La Rapide

La Rapide (The Rapid) was  built in 1881 and was noted for achieving a speed of . La Rapide grouped the boiler, the engine and the controls at the front of the vehicle, thus making it possible for it to be driven by a single operator.

Narotam Sekhsaria. Narrotam Satyanarayan Sekhsaria is an Indian industrialist and philanthropist.

Early life 
Born in Chirawa, Rajasthan, India in the Seksaria Marwari trading family in 1950, he was brought up in Bombay and was educated as a chemical engineer from the city's prestigious University Department of Chemical Technology (UDCT), now known as Institute of Chemical Technology, Mumbai.

Career 
He started his career at his family business, predominantly trading cotton. He subsequently switched career in the early 1980s, giving up trading to set up Ambuja Cements. Over the next decade, Mr Seksharia built Ambuja Cements into one of the world's most efficient, profitable, and greenest cement companies. It was among the earliest companies in India to develop its own captive sea-ports and use sea transportation to ship cement across the country and abroad. Ambuja Cements went on to acquire a stake in ACC Limited, then India's best known and geographically speaking, the largest cement company. In 2005, Mr Sekhsaria, then still in his 50s, did something unthinkable among family-controlled businesses in India. He divested his interest in Ambuja Cements and ACC Ltd. and ceded control to Holcim Group, the Swiss multinational cement giant. Mr Sekhsaria continues to be the non-executive chairman of Ambuja Cements and ACC Limited.   

Mr Sekhsaria is the chairman of Ambuja Cement Foundation, which he set up as part of Ambuja in the early 1990s and has since grown to become one of India's most extensive corporate CSR programs. It does work in the areas of rural development through agriculture, health, education,skill-building and women's empowerment initiatives.

He is also the Chairman of the Narotam Sekhsaria Foundation, the philanthropic arm of his family office, which funds and supports individuals and organisations working in health, education, livelihoods, governance, art and culture.

Valmet PIK-23 Towmaster. The Valmet PIK-23 Towmaster or Suhinu is a Finnish two-seater glider-towing/primary trainer aircraft built entirely out of composite materials in the early 1980s.

Design and development
The Finnish technology students aviation club (PIK) suggested in the 1970s, that a new aircraft should be developed for glider towing. The work focused on the improvement of a previous design, the PIK-19 Muhinu. Later on, the Helsinki University of Technology and Valmet Oy joined the project and the design process started from scratch. The goal was to develop a target/glider tower, which also could be used for basic training. It was given the name "PIK-23 Towmaster".

Only two aircraft were manufactured, one at Valmet and one at the Helsinki University of Technology. The first aircraft, OH-TOW, made its maiden flight on March 22, 1982, flown by Mikko Järvi. The second aircraft, OH-TUG, flew the following year.

Valmet marketed the aircraft intensively, but no orders followed. It was also investigated if the aircraft could be sold in parts, for self-assembly, in order to lower the price. In its intended role as a glider tower, the PIK-23 has been quite successful.

Manual pulse generator. A manual pulse generator (MPG) is a device for generating electrical pulses (short bursts of low current) in electronic systems under the control of a human operator (manually), as opposed to the pulses automatically generated by software. MPGs are used on computer numerically controlled (CNC) machine tools, on some microscopes, and on other devices that use precise component positioning. A typical MPG consists of a rotating knob that generates pulses that are sent to an equipment controller.  The controller will then move the piece of equipment a predetermined distance for each pulse. 

For example, the handwheel of a typical CNC control will move any of the slides of the machine by one minimum increment, such as 1 micrometre or 1 ten-thousandth of an inch, for each pulse, and the handwheel will give one ratchet-like click or other haptic click to confirm to the user that a single increment occurred. Several selector switches control the handwheel's output: one allows each of the machine's axes (X, Y, Z, and so on) to be selected in turn; another shifts through several ranges of output, so that one click of the wheel is either one minimum increment, 10 times that, or 100 times that. 

The modern trend in CNC user interface design is to place the MPG on a handheld pendant that the operator can carry, making it conveniently independent from the main control panel, just as a game controller is independent from the video game console.

Mooney M10 Cadet. The Mooney M10 Cadet is a light airplane manufactured by the Mooney Aircraft Company in 1969 and 1970. The M10 is derived from the ERCO Ercoupe, the type certificates for which Mooney purchased from the Alon Corporation in 1967.

Design

The M10 is similar to the Alon A2-A, and indeed a handful of "Mooney A2-As" were built in Kerrville in 1968 before changeover of Mooney's production line was completed.  According to the FAA Type Certificate Data Sheet, the "Model 10 is similar to Model A2-A except for new design empennage, ailerons and fuel tank vent."  The most obvious difference is that the M10 replaces the iconic Ercoupe-style dual vertical stabilizer with a tail designed to allow the airplane to spin.  Changes to the ailerons, along with replacement of the A2-A's tail, were motivated by Mooney's intent to market the M10 as a trainer: student pilots receiving training in a non-spinnable airplane, as the Ercoupe was, were issued FAA pilot certificates carrying the restriction that they could only fly airplanes which were "characteristically incapable of spinning"; thus the spinnable tail was necessary to turn the A2-A into a general-purpose trainer. Given that they were replacing the tail, Mooney's engineers opted to give it the "backward" profile characteristic of the M20 series. Although the M10's empennage has the same silhouette as the "big Mooneys", it does not swivel the way the M20's does; the Cadet's tail is a conventional design with fixed horizontal stabilizer, hinged elevator, and trim tabs.

The two type certificates that cover all Ercoupe variants, including the Mooney M10, are currently owned by Univair Aircraft Corporation, in Aurora, Colorado, USA.

Marine architecture. Marine architecture is the design of architectural and engineering structures which support coastal design, near-shore and off-shore or deep-water planning for many projects such as shipyards, ship transport, coastal management or other marine and/or hydroscape activities. These structures include harbors, lighthouses, marinas, oil platforms, offshore drillings, accommodation platforms and offshore wind farms, floating engineering structures and building architectures or civil seascape developments. Floating structures in deep water may use suction caisson for anchoring.

Tachikawa Ki-55. The Tachikawa Ki-55 was a Japanese advanced trainer.

Design and development
The excellent characteristics of the Tachikawa Ki-36 made it potentially ideal as a trainer. This led to the development of the Ki-55 with a single machine gun. After successful testing of a prototype in September 1939, the type was put into production as the Tachikawa Army Type 99 Advanced Trainer.

In all, 1,389 Ki-55 were constructed before production ended in December 1943 - with Tachikawa having built 1078 and Kawasaki 311.

Both the Ki-55 and the Ki-36 were given the Allied nickname Ida.

Japanese destroyer Ayanami (1909). ("cross wave") was the last of 32  destroyers built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century.

Design and description
The Kamikaze-class destroyers were improved versions of the preceding . They displaced  at normal load and  at deep load. The ships had a length between perpendiculars of  and an overall length of , a beam of  and a draught of . The Kamikazes were powered by two vertical triple-expansion steam engines, each driving one shaft using steam produced by four Kampon water-tube boilers. The engines produced a total of  that gave the ships a maximum speed of . They carried a maximum of  of coal which gave them a range of  at a speed of . Their crew consisted of 70 officers and ratings.

The main armament of the Kamikaze-class ships consisted of two 40-calibre quick-firing (QF)  12 cwt guns on single mounts; the forward gun was located on superstructure, but the aft gun was at the stern. Four 28-calibre QF three-inch 8 cwt guns on single mounts were positioned abreast the superstructure, two in each broadside. The ships were also armed with two single rotating mounts for  torpedoes between the superstructure and the stern gun. When Isonami was converted into a minesweeper in 1924, she was rearmed with a pair of  3rd Year Type guns taken from older ships on single mounts and the three-inch 8 cwt guns were removed.

Construction and career 
Ayanami was launched at Maizuru Naval Arsenal on 20 March 1909 and completed on 26 June. The ship served during World War I and participated in the Siberian Expedition. She was converted into a minesweeper on 1 December 1924 and was renamed W-9 on 1 August 1928. The ship was decommissioned on 1 June 1930, but she continued in service as a tugboat and a dispatch boat until 19 April 1935 and was subsequently scrapped.
