Victoria 18. The Victoria 18 is an American trailerable sailboat that was designed by Canadian G. William McVay. It was built in the United States 1977 to 1983.

Most boats built were sloop rigged, but a few were built as cutters with a bowsprit. A small number were built as the Victoria 17, with a shorter hull and an outboard rudder.

The Victoria 18 is a cabin development of G. William McVay's 1967 open boat design, the Minuet.

Production
The design was built by G. William McVay's son, Bill McVay, at his company, Victoria Yachts in DeBary, Florida, United States. Production ran from 1977 until 1983, with about 600 examples of the design completed, but it is now out of production.

Design
The Victoria 18 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig with tapered anodized aluminum spars. The hull has a spooned raked stem; a raised counter, angled transom; a keel-hung rudder controlled by a tiller and a fixed long keel. It displaces  and carries  of ballast.

The boat has a draft of , allowing ground transportation on a trailer.

An optional stern mount allows fitting a small outboard motor of up to  for docking and maneuvering.

The design has sleeping accommodation for two people, plus a cooler. A cockpit boom tent was a factory option. Ventilation is provided by four opening ports. For stowage the design has a lazarette.

For sailing the design is equipped with a cockpit  in length, genoa tracks, winches and jib roller reefing. For racing additional equipment allowed under the class rules can include an adjustable backstay, a boom vang, barber haulers and a spinnaker. The boat is usually raced with a crew of 1-3 sailors.

Electrolytic iron. Electrolytic iron is a form of high purity iron, obtained by electrolysis. It has a high purity greater than 99.95% with trace elements accounting for only a millionth of a decimal.

Overview 
To obtain the best qualities that iron has to offer like high ductility, more corrosion resistance, and better magnetic characteristics; a chemical process must occur to remove impurities. The most effective process is through electrolysis that takes commercial grade iron and minimizes the C, S, Mn, and other trace element levels to become one of the highest grades of iron on the market known as electrolytic iron. Once the iron is in its purest state, it can be then used as a component in alloys. Alloys with high purity elemental makeups have specifically enhanced properties such as ductility, tensile strength, toughness, fatigue strength, heat resistance, and corrosion resistance, on which each element draws from their best inherent properties and collectively contributes to the alloy as a whole.

Production method of electrolytic iron 

Smelting is typically classified into two procedures: the wet process and the dry process. Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution. This action causes a chemical reaction called electrolytic refining. The result of electrolytic refining is electrolytic iron.

An anode  (raw material) and a cathode (base plate) are immersed into an electrolyte including iron ions and other components. Moreover, current flows between the anode and the cathode. As a result, iron is deposited on the surface of the cathode due to a difference in an ionization tendency, and high purity iron can be obtained.

TOHO ZINC CO.,LTD. is producing and selling electrolytic iron refined by the wet process on an industrial scale. TOHO ZINC CO.,LTD. accounts for the top market share of high purity iron in wet type process. The purity of the iron sold is from 99.9% to 99.999%, especially including the gas components of O, N, C, and H.

Other method 
High purity iron is also produced in dry process. VOD (vacuum oxygen decarburization), and ESR (electro-slag remelting) are known as dry process. VOD is a process of melting pure iron in a vacuum and degassing. ESR (electro-slag remelting) method is a process of dripping the molten metal refining pure iron as an electrode. 
Moreover, an ion exchange method is known as wet type process in addition to electrolytic refining.

Application 
Electrolytic iron is utilized by the aerospace sector in areas where components are safety critical. Landing gear, engine shafts in jet aircraft,  and gas turbines of generators, are areas that require the use of electrolytic iron. It is also used in research and development, special alloys (maraging steel, Ni-base alloys, Ti alloys), sputtering targets, chemicals (etching liquids), etc. In addition, it is used as a raw material for Japanese swords produced using traditional Japanese techniques.

CID-201. CID 201 was a digital computer produced in Cuba in 1970.

History
Cuba had already produced the analog computer SILNA 999. In 1969, the Cuban leader Fidel Castro asked during a visit to the University of Havana if Cuba could produce a digital computer.
The  (CID, "Center for Digital Researches") was formed.
The project was directed by Luis Carrasco and mostly designed by Orlando Ramos.
The first version was designed using transistors, but after the introduction of integrated circuits, the design was changed.
It was inspired by the American 1965 PDP-8.
The components were mostly Japanese, due to the American embargo on Cuba. 

On 18 April 1970, the first computer was produced. 
It was named CID 201 following the earlier digital watch CID 101.
It could do 25 000 additions/second.
Its memory held 4 096 12-bit words.
It was considered a third-generation computer.

It could be programmed in LEAL (, "algorithmic language").

A later version was the CID 201-A.
The CID also produced the CID 201-B, CID-300/10, CID-1408 and CID-1417. 
Among the peripherals produced, several thousands of displays were exported to the Soviet Union.

Application
The first computer was installed in the sugar refinery Camilo Cienfuegos to control the railroad traffic during the sugarcane harvest.
Another one was installed in the Ecuador refinery.

Legacy
 On 2010, the Cuban Administración Postal issued a stamp commemorating the CID-201.

Vacuum arc thruster. A vacuum arc thruster (VAT) is a form of electric spacecraft propulsion. It uses a vacuum arc discharge, across an insulator, between two electrodes to produce thrust. A metal plasma is produced from micrometer-size cathodic spots. Thus, whereas the insulator is used as propellant in a pulsed plasma thruster, in a VAT the metallic cathode is consumed as propellant.

Tachikawa KKY. The Tachikawa KKY, full name Tachikawa Army Small and Light Ambulance Aircraft, was designed to rescue injured or sick patients from places without established airfields. Following two earlier prototypes, twenty-one production examples were built between 1936 and 1940 and served in the Second Sino-Japanese War.

Design and development
In August 1932, the Japanese Army placed an order for a small ambulance aircraft, capable of using rough airstrips and holding two stretcher cases and a medical attendant, with what was then the Aeroplane Factory of Ishikawajima Shipbuilding Company. Though the prototype was completed in December 1933, its development was protracted, and it was not ready for production until 1936. By then, the Ishikawajima Company had become the Tachikawa Aeroplane Co.

It was a single bay cabin biplane with wings attached to the upper and lower longerons and braced on each side with near-parallel interplane struts. The wings had wooden structures and were fabric-covered.

The KKY was powered by a  Cirrus Hermes IV four cylinder air-cooled, inverted inline engine and the later KKY-2 by a  Gasuden Jimpu seven cylinder radial engine. The fuselage had a welded steel tube structure, flat-sided behind the engine, with a windowed cabin that included the pilot's seat just ahead of the wing leading edge with the patients and attendant under the wing. The tail, with an aluminium structure and fabric-covered, was conventional with a tailplane on top of the fuselage and braced to it from below. The vertical tail had a strongly-blunted triangular profile.

As its purpose was to rescue patients from rough airfields or unmade airstrips, the ambulance needed a robust undercarriage. This had split axles mounted on a short, central, V-strut from the fuselage underside. Both short, faired shock absorber legs and their rearward drag struts were mounted on the lower fuselage longerons. Wheels with wide, low-pressure tires were available for missions to unmade strips.

Operational history 
Twenty-one Aikoku-go (privately funded) production KKYs were built between 1936 and 1940. They were active in the Second Sino-Japanese War, which began in 1937 and became part of World War II, when China entered on the Allies' side shortly after the attack on Pearl Harbor.

Variants
KKY As described. Two prototypes plus production aircraft from 1936 to October 1938.
KKY-2 The production aircraft from October 1938, powered by a  Gasuden Jimpu seven cylinder radial engine driving a wooden propeller. It had increased area wings with Clark Y airfoils, braced with N-type interplane struts. 
KS Small Survey Aircraft A modification of the KKY-2 into a civil photographic survey aircraft for the Department of Railways. It had additional large windows in the cabin sides behind the wing trailing edge and another in the cabin floor, a survey camera and seats for a survey crew of three. Two were built in 1939.

Orca (AUV). The Orca is an autonomous underwater vehicle (AUV) that is under development by Boeing and Huntington Ingalls Industries (HII) for the United States Navy.

The Orca dates back to September 2017, when the Navy issued contracts worth about US$40 million each to Boeing, which had partnered earlier in the year with HII to build uncrewed submarines, and Lockheed Martin to develop competing designs for an extra-large unmanned undersea vehicle (XLUUV) capable of autonomous operation on missions up to several months in duration.  In February 2019, the Navy awarded the Boeing/HII consortium a $43 million contract to begin work on building four of their XLUUVs, the design of which would be based on Boeing's earlier AUV Echo Voyager.  The following month, the Navy added a fifth vehicle to the order, with the total value of the contract reaching $274.4 million.  Orca deliveries were planned to be completed by the end of 2022. The Navy took delivery of the first Orca in December, 2023.

The basic Orca design shares a  length with Echo Voyager, but the Orca will incorporate a more modular construction, primarily for the capability to be built with an additional payload module of up to  long and a capacity of  for a total length of .  The Navy specified the ability to adapt the Orca platform according to mission, with the ability for surveillance, submerged, surface, and electronic combat, and minesweeping.  The vessel will be powered by a hybrid diesel/lithium-ion battery system, which powers the Orca by battery while submerged and recharges the batteries with diesel generators while surfaced.  Maximum speed is , though the typical service speed is about , which gives the Orca a range of up to  with an endurance of several months.

John Beech (artist). John Beech is a British-American artist living and working in Brooklyn, New York.

Life and work 

John Beech was born in 1964 in Winchester, England. He moved to the United States at a young age and studied at the University of California, Berkeley, where he graduated with a Bachelor of Arts in 1986.

Beech's work across the fields of sculpture, painting, drawing and photography is defined by the use of humble materials such as rubber car floor mats, raw plywood, containers and other overlooked objects, reconfigured into painted and textured assemblages that draw attention to shape and scale. Beech is interested in "the object quality of things", in letting the form and materials demonstrate themselves. A relevant element in his work is his choice of materials. "I'm interested in fusing the visual vocabulary of utility and abstract art", Beech says. Ordinary objects such as dumpsters and patched subway platforms catch his eye and provide the basis for nuanced works of art. 

Another aspect of Beech's work is his collection of more than six hundred Found-Photo Drawings. He selects the secondhand photos according to imagery or imperfections and alters them to extend and articulate a relation between photographic information and applied matter. Beech considers a piece complete when the photograph and drawing conjoin to become a resonant new entity, no longer tied to an historical moment.

Beech's work has been exhibited widely in the United States and Europe."Beech wants to jog us out of perceptual habit. His idiom is a poetics of normal wear and tear." –Kenneth Baker, San Francisco Chronicle
