Summit 2. The Summit 2, also called the Summit II, is an American powered parachute that was originally designed and manufactured in 1999 by Aircraft Sales and Parts of Vernon, British Columbia and now produced by Summit Aerosports of Yale, Michigan.

Design and development
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules as a two-seat trainer, or as an amateur-built aircraft. It features a parachute-style high-wing, two-seats-in-tandem, tricycle landing gear and a single  Rotax 582 engine in pusher configuration. The  Hirth 2706,  Rotax 503,  Rotax 912 and the  HKS 700E engines are factory options.

The aircraft is built from a combination of 6061-T6 aluminium, 4130 steel and stainless steel tubing. The canopy is attached to the carriage at four points, instead of the more conventional two points, to improve stability. In flight steering is accomplished via rail-mounted sliding foot pedals that actuate the canopy brakes, creating roll and yaw. Steering is via a 2:1 ratio system of pulleys that reduce the force required and increase control authority. The lack of pivoting control bars allows cockpit fairings to be fitted. On the ground the aircraft has lever-controlled nosewheel steering. The aircraft is factory supplied in the form of an assembly kit that requires 20–30 hours to complete.

CANSA C.4. The CANSA C.4 was a single engine, open cockpit, tandem seat training aircraft and tourer flown in Italy in 1942.

Design and development

The last of a series of three CANSA trainer designs, preceded by the C.5 and C.6, the C.4 was the only monoplane. It had a low, straight tapered wing; no flaps were fitted. The empennage was conventional, with the tailplane mounted on top of the fuselage.  The elevators were split so that the unbalanced rudder, which extended to the bottom of the fuselage, could move between them.  The fin and rudder together were straight edged and round topped.

The fabric covered fuselage was flat sided, with a rounded decking. The two occupants sat in separate cockpits, the forward one at the wing leading edge and the second close behind over mid-chord.  The cockpits were open but fitted with windscreens and short sidescreens.  The C.4 was powered by a 67 kW (90 hp), 4-cylinder inline, air-cooled, inverted CANSA C.80 engine.  It had a fixed, conventional undercarriage with a tailskid.

The C.4 was built as both a training aircraft and a tourer but production numbers are not known.

Porte-class gate vessel. The Porte-class gate vessels were a class of five boom defence vessels built in the early 1950s and operated by the Royal Canadian Navy (RCN) and Canadian Forces (CF) during the Cold War. The class derived its name from the gates of the French fortifications of Québec and Louisbourg and was designed by the RCN as a replacement for World War I-era s used to operate anti-submarine booms during World War II. The Porte class were used primarily as training vessels during the Cold War.

Design and description
The Porte class were designed with the possibility of commercial adoption of the design by the Canadian fishing industry. The gate vessels were planned for use as auxiliary vessels during peacetime. The Porte class was of a trawler design, and were designed to operate the anti-submarine booms for harbour defence. They were also capable of being fitted for minelaying.

The Porte class were  long with a beam of  and a draught of . They displaced  fully loaded and had an initial complement of 3 officers and 20 ratings. The Porte class were powered one Fairbanks-Morse 6-cylinder diesel engine driving one shaft creating . This gave the vessels a maximum speed of . The vessels had a range of  at . They were equipped with one Racal Decca navigation radar operating on the I band. The ships were armed with one 40 mm gun placed forward.

Ships

Service history
The first Porte-class vessel was ordered September 1949. Porte Saint Jean and Porte Saint Louis were based at Halifax, Nova Scotia and Porte Dauphine, Porte Québec and Porte de la Reine at Esquimalt, British Columbia. From 1958 to 1974, Porte Dauphine was loaned to the Department of Transport (DOT) as an environmental research ship on the Great Lakes, before transferring to the West Coast via the Panama Canal. Porte Dauphine was modified for DOT use, which involved the installation of a widened wheelhouse and a cafeteria. The vessels were used to train naval reserve crews in key trades such as navigation, diesel mechanics, communications and logistics. Porte Saint Jean and Porte Saint Louis began training on the Great Lakes in 1953, working with  in Hamilton, Ontario. They sometimes travelled to Bermuda for training. In 1973, Porte Saint Jean and Porte Saint Louis sailed into the eastern Arctic. With the arrival of the s in the mid-1990s, the Porte class was retired. Porte Dauphine was the first, discarded in December 1995, followed by Porte Saint Jean and Porte Saint Louis in March 1996 and Porte Québec and Porte de la Reine in December 1996.

Silver thiocyanate. Silver thiocyanate is the silver salt of thiocyanic acid with the formula AgSCN. Silver thiocyanate appears as a white crystalline powder. It is very commonly used in the synthesis of silver nanoparticles. Additionally, studies have found silver nanoparticles to be present in saliva present during the entire digestive process of silver nitrate. Silver thiocyanate is slightly soluble in water, with a solubility of 1.68 x 10−4 g/L. It is insoluble in ethanol, acetone, and acid.

Structure
AgSCN is monoclinic with 8 molecules per unit cell. Each SCN− group has an almost linear molecular geometry, with bond angle 179.6(5)°. Weak Ag—Ag interactions of length 0.3249(2) nm to 0.3338(2) nm are present in the structure.

Production

Solution reaction 
Silver thiocyanate has been commonly produced by the reaction between silver nitrate and potassium thiocyanate.

Ion-exchange route 
Silver thiocyanate may be formed via an ion exchange reaction. In this double displacement reaction, silver nitrate and ammonium thiocyanate are dissolved in distilled water to produce silver thiocyanate and ammonium nitrate.

Additionally, silver thiocyanate can be formed through the double displacement reaction between ammonium thiocyanate and silver chloride to form a precipitate of silver thiocyanate.

Uses 
The most common use of silver thiocyanate is as a silver nanoparticle. Silver thiocyanate nanoparticles have been found in saliva throughout the entire artificial digestion of silver nitrate. The nanoparticles can also be used as good ion conductors.

Silver thiocyanate has also been used to absorb uv-visible light at values less than 500 nm. At longer wavelengths, silver thiocyanate has been found to have good photocatalytic properties.

Characterization 
Upon production, silver thiocyanate can be characterized through a wide range of techniques: x-ray powder diffraction (XRD), x-ray photoelectron spectroscopy (XPS), Raman Spectroscopy, ultraviolet photoelectron spectroscopy (UPS), and thermogravimetric analysis (TGA).

Samuel Lake. Samuel Lake AM (1842–1887) was a general merchant, civil engineer, and pioneering designer and builder of steam trawlers, from Dartmouth, Devon in the United Kingdom.

In his civil engineering work in the 1860s he constructed one of the first rows of terraced cottages to be built out of poured shuttered concrete, using what was then a revolutionary building material and technique. They were then known as Coombe Terrace, today numbers 12 to 21 Coombe Road, and were built for Lake himself and for his employees.

Lake's trawler work was in conjunction with George Parker Bidder, also of Dartmouth, and proved to be a technical success, but not at that time to be commercially viable.

Lake spent a substantial part of his life in India. In 1867 Lake of the Bombay Reclamation Company was awarded the Albert Medal for his bravery in helping rescue the crew and some 400 Muslim pilgrims from a shipwreck off Bombay. He returned to Dartmouth in 1866.

Lake was contracted in 1879 to build Milford Haven and in 1881 Felixstowe Docks but went bankrupt.

Lake Street in Dartmouth is named after him.

Eugene Reising. Eugene Gustavus Reising (November 26, 1884 – February 21, 1967) was an American inventor who designed the M50 Reising submachine gun in 1938. Reising was a ranked competitive target shooter. An ordnance engineer, Reising was the recipient of more than 60 firearm patents. Following his work with Harrington & Richardson, he designed semi-automatic rifles for Mossberg & Sons, Marlin, Savage, and Stevens.

Biography
Of Swedish ancestry from a family that came to Delaware in 1635, Reising was born in Port Jervis, New York. He was the son of a railroad engineer who died when Eugene Reising was an infant. Reising attended Lehigh University for  three years, then worked as a cowboy in Texas and Mexico for a few years. On returning to the U.S. he went to work for Colt, testing and selling guns. He worked with John M. Browning on the development of the Colt Model 1911 pistol.

In 1911, Reising served in Company A of the Connecticut National Guard, winning a championship in expert riflemanship and giving demonstrations of the rapid reloading of semi-automatic pistols. In the same year, he demonstrated a 9.8-mm version of the Colt pistol, which was adopted as the M1911 by authorities in three Balkan countries, but two years later, he was fired from the company for using a Luger pistol at a target shooting competition.

In October 1925, Reising was indicted for violating the Sullivan Act after supplying pistols and Maxim Silencers to a member of the Cowboy Tessler gang, a group that was captured after a string of robberies and a gun battle with police in New York. He pleded guilty to unlawful possession of firearms and was sentenced to fifteen months' imprisonment on Welfare Island.

In 1938, Reising began work on a new submachine gun. He submitted his design to Harrington and Richardson, and in March 1941, they started manufacturing it as the Model 50. Approximately 100,000 of these were made, and many were used in World War II.

His wife, Frances Rose Reising, died in Hartford on April 26, 1947. He remarried, to Alice V. Fohlin.

Eugene Reising died in Worcester, Massachusetts, on February 20, 1967.
