Rans S-20 Raven. The Rans S-20 Raven is an American homebuilt aircraft that was designed by Randy Schlitter and is produced by Rans Designs of Hays, Kansas, introduced at AirVenture in August 2013. The aircraft is supplied as a kit for amateur construction and it is anticipated that it will later be offered as a complete ready-to-fly-aircraft in the light-sport aircraft category.

Design and development
The S-20 combines features from the Rans S-6 Coyote II and Rans S-7 Courier models. It differs from the S-6 in having the whole fuselage made from welded 4130 steel tubing and not just the cockpit cage and it uses the S-7's wings.

The aircraft features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via bowed-out top-hinged doors to give increased shoulder room, fixed conventional landing gear or optionally tricycle landing gear made from 7075 aluminum with wheel pants and a single engine in tractor configuration.

The aircraft fuselage is made from welded 4130 steel tubing, while the wings are of aluminum construction, with all surfaces covered in doped aircraft fabric. Its  span wing mounts flaps, has a wing area of  and is supported by "V" struts with jury struts. The cabin has a width of  and features a large overhead skylight. The acceptable power range is  and the standard engines used are the  Rotax 912ULS or the  ULPower UL350iS powerplant.

The aircraft has a typical empty weight of  and a gross weight of , giving a useful load of . With full fuel of  the payload for the pilot, passenger and baggage is .

The manufacturer estimates the construction time from the supplied kit as 500–700 hours, with kits forecast to commence shipping in February 2014. A ready-to-fly LSA version is expected to be on the market by late 2015 at a cost of about US$120,000.

Operational history
In January 2014 one example was registered in the United States with the Federal Aviation Administration, although a total of two had been registered at one time.

Jobu. Jobu Mekaniske Verksted AS (Jobu Mechanical Manufacturers) in Drøbak, Norway, was founded in 1947 by timber merchant Trygve Johnsen and gunsmith Gunnar Busk in 1947. The company produced chainsaws and other forestry machines in the period 1948 to 1979. The brand continued until 1983.

Johnson and Busk were themselves responsible for the construction of the first commercial chainsaw, "Jobu Senior," which had an "Aspin" engine with a standard carburetor with float chamber. Whenever the saw was placed on the side, the carburetor had to be rotated accordingly. Jobu Senior weighed 17.5 kg and was only applicable for felling and bucking.
The next model was Junior, which was released on the market in 1952. The engine in Junior was manufactured by Jobu themselves. Junior came with its predecessor carburetor solution that still had to be rotated. The weight was reduced to 10.4 kg. This saw became very popular, and around 40 000 units were produced. Jobu Tiger, which came in 1960, was a major advance. This model had a diaphragm carburetor that worked in all positions.

Jobu was for a long time the market leader in Norway. In the latter half of the 1960s and in the 1970s Jobu saws were also exported to various countries in Europe and even the United States.
Jobu produced several different options for their chainsaws. Best known is a propeller that converted the chainsaw to an outboard motor. This was available for both Senior and Junior Jobu. They also produced an auger for Junior Tiger .
The company was later purchased by Christiania Spigerverk in Oslo, which later merged with Elkem to become Elkem Spigerverket. In 1983 it was sold to Electrolux in Sweden, and the production of Jobu-saws was terminated.

IIL IS-11. The IIL IS-11 was an aerobatic, single seat glider, designed and built in Romania in 1959. It was built in small numbers.

Design and development
From about 1950 to his death in February 1981, Iosif Silimon was Romania's most prominent glider designer, his aircraft distinguished by his initials. His single seat IS-11  was a wooden, high wing aerobatic  sailplane.

The cantilever high wing of the IS-11 was mounted with a dihedral of 2.5°. It was built around a single spar with a plywood covered torsion box ahead of it around the leading edge. The rest of the wing was also ply covered. In plan the wing was symmetrically straight tapered. Its mass balanced ailerons were slotted and fabric over ply covered.  The IS-11 had short span spoilers, opening both above and below the wing, mounted at mid-chord just inboard of the ailerons. The wing tips carried the small, streamlined bodies known as salmons, common at the time.

The fuselage of the IS-11 was an oval section  plywood monocoque.  The pilot sat in a semi-reclining position in a single seat cockpit under a single piece, side opening perspex canopy which, with a short, fixed transparency behind it stretched from the nose into the leading edge of the wing.  Its undercarriage comprised a very short, rubber sprung skid under the nose and a fixed, unsprung monowheel semi-recessed into the fuselage under the forward wing and fitted with a brake.  From the high wing the fuselage tapered aft to a conventional empennage.  A narrow, ply covered fin and a fabric covered rudder which extended down to the keel together formed a straight edged vertical tail with rounded heel and tip. The fin also mounted a straight edged, fabric over ply covered tailplane placed just above the fuselage, carrying straight tapered, similarly skinned elevators.  These were balanced by a bob weight within the fuselage and had gaps both at their roots to clear the fin and at their tips to clear rearward tailplane extensions, with a small central cut out for rudder movement.  There was a trim tab on the starboard elevator and a tail bumper under the rudder hinge.

The IS-11 was first flown on 16 December 1959 and a few more were built during 1961.

Collabrification. Collabrification came from the foundation of making mobile education more collaborative. From the start, it was designed to make something that was inherently non-collaborative and make it collaborative. The infrastructure has been used in the IMLC, University of Michigan, University of Texas, and the department of Mathematics and Information Technology at The Hong Kong Institute of Education. By building real-time, synchronous collaboration into mobile infrastructure, people build on the Four C's: critical thinking, communications, collaboration, and creativity. Collabrification of mobile and web applications allows people to build relationships, increase shared understanding, increase productivity, organize thoughts, and make mobile technology, specifically related to mobile applications, more fun and engaging.

Mobile collaboration
The first set of collabrified mobile apps were WeKWL, WeMap, WeSketch, WeCollabrify, YesWeKhan,

Winfield Scott Sims. Winfield Scott Sims (April 6, 1844 – January 7, 1918) was an American inventor.

Sims was born in New York City, son of Lindsay D. and Catherine B. Sims. Sims attended the public schools of Newark, New Jersey. He had just graduated from the high school when the American Civil War broke out. He enlisted in the 37th Regiment New Jersey Volunteers and served until 1864. Sims has specialized in the application of electric power to marine vehicles and in the invention of high power war weapons. He was the first to apply electricity to the propulsion of torpedoes.

Among his inventions is a submarine boat with a cylindrical hull of copper having conical ends and with a screw propeller and rudder operated by electric power generated on shore or on ship board, by means of which the torpedo is propelled, guided and exploded. Among Sims’ earlier inventions were various devices in electromagnets and the construction of an electric motor, weighing 45 pounds for light work, with a battery of twenty half gallon Bensen cells that propelled an open boat sixteen feet long with six persons on it, at the rate of four miles an hour. His invention of the submarine torpedo boat was followed by the devising of a boat with a speed of 22 miles an hour to carry a 500-pound charge of dynamite.

He invented also a wireless dirigible torpedo for the Japanese Government in 1907. The Sims-Dudley dynamite gun, also of his invention, was used by the Cuban insurgents, and, at the battle of Santiago by the "Rough Riders". Others of his designs are a dynamite gun for use with dirigible war ships and an aeroplane dynamite gun.

Sims was president of the New York Ordnance Company. He died in Newark in 1918.

Münster freight bypass railway. The Münster freight bypass railway () is an electrified and mostly single track bypass railway in Münster in the German state of North Rhine-Westphalia. It is only regularly used by freight to avoid Münster Hauptbahnhof.

History 

The bypass was opened on 5 October 1930 and is the most recent major railway construction project in Münster. The reason for its construction was that after the First World War there was a great increase freight traffic on the line while Münster Hauptbahnhof had no through tracks dedicated to freight and such tracks could not be built due to lack of space.

Originally, the plan was also to build a two-sided marshalling yard (approximately in the area between the Dortmund–Ems Canal and Kaldenhofer Weg), which would be connected via the bypass to all major routes to Münster. However, this was not implemented for cost reasons.

Electrification of the line was completed on 25 May 1968.

The bypass is proposed to be closed under the Netz (network) 21 project, which would relocate freight traffic on the routes between the North Sea ports and the Ruhr to other lines via Minden, but, because some of the required upgrades have still not been completed, it is still open.

Route 

The bypass begins at Bbf (Betriebsbahnhof, “operations” station, which mainly consists of passing loops) Mecklenbeck on the Wanne-Eickel–Münster line. It runs east around the city and ends at Bbf Sudmühle on the Münster–Osnabrück line. In addition, there is also possible to connect to Lechtenberg junction on the Münster–Hamm railway to run over the bypass towards Sudmühle (or vice versa).

Most of the line is built as single track. Only the connection curve to the Hamm line and the section from Pleister crossover to Bbf Sudmühle are duplicated. It has three tracks at Bbf Kanal. The track is built mainly on an embankment and has no level crossings. The Bbf Mecklenbeck–Bbf Kanal section it partially built in a cutting. Along the way there are many bridges, the largest of which crosses the Dortmund–Ems Canal.

Saxon I. The Saxon Class I () was a class of steam locomotive operated by the Royal Saxon State Railways with a  axle arrangement. The engines were supplied by various manufacturers for mixed duties.

History 
In 1871, the Royal Saxon State Railways grouped into Class I all those locomotives that had been procured from various manufacturers in the early years of state railway construction in the Kingdom of Saxony. These were all vehicles with a leading carrying axle and two coupled axles. The oldest locomotives of this class were procured in 1847 by the Saxon-Bavarian Railway. The last Class I locomotive was retired in 1887. No museum pieces have survived.

Multi-source agreement. in the telecommunications industry, a multi-source agreement (MSA) is an agreement among multiple manufacturers to make products which are compatible across vendors, acting as de facto standards, establishing a competitive market for interoperable products.

Products that adhere to multi-source agreements (MSAs) include: optical transceivers, such as the SFP, SFP+, XENPAK, QSFP, XFP, CFP etc.; fiber optic cables; and other networking devices. MSAs strictly define the operating characteristics of these network devices so that system vendors may implement ports in their devices (e.g. Ethernet switches and routers) that allow MSA compliant devices produced by name brands, as well as third party vendors, to function properly.
