Motorcraft 2150 carburetor. The Motorcraft 2150 is a Ford (also used by AMC) 2-barrel carburetor manufactured from 1973 through 1983, based heavily on its predecessor, the Autolite 2100 carburetor.

The 2150 improved on the 2100s design through the introduction of a variable air bleed system, which keeps the air to fuel mixture better balanced throughout the carburetor's full range of operation. The 2150 models from 1983 to 1986 were electronic feedback carburetors equipped with Ford's EEC-IV.

Variations
Unlike the Autolite 2100, the Motorcraft 2150 was available only in two venturi sizes. Both were available in manual and automatic transmission configurations.

1.08 venturi, 287 CFM
These 2150s were used on Ford engines up to the 302 Windsor in cubic displacement.

Ford engines commonly equipped with the 1.08 venturi 2150:
 1975–1986 2.8 L V6
 1982–1983 3.8 L Essex V6
 1973–1983  I6
Note: The 250-I6 is derived from the Falcon line (144-170-200). U.S. versions were only available with an integral cast head and intake making them only able to accept a one-barrel carb. Foreign versions were also made with typical two-piece intake and head.
 1973–1983  Windsor 351W 5.8L light truck/van

The last Ford vehicles to leave the factory with 2150 carburetors were 1986 Aerostars equipped with the 2.8 L V6.

1.21 venturi, 351 CFM
These larger 2150s were generally used in large Ford passenger cars and trucks equipped with 335-series engines. These were also used, with the addition of an altitude compensator, on Jeep Grand Wagoneers equipped with the AMC 360 V8.

Ford engines commonly equipped with the 1.21 venturi 2150:

1973-1982  Windsor
1977-1982  351M
1977-1979 

AMC engine equipped with the 1.2 venturi 2150 with altitude compensator:

1981-1991 AMC  Gen 3 “Tall Deck”

Walker Woolen Mill. The Walker Woolen Mill, also known as the Foster Mill, was built in Wilton, Maine, in 1840. It was expanded and refurbished over the next 40–50 years using local local pine and wood eventually shipped using the transcontinental railroad.

Maine is the most wooded state in the United States, and has a long history of manufacturing everything from shoes to paper.  Charles Forster, a later owner who has been called the "father of the toothpick" used the mill to produce the world's first toothpick in 1881. It later housed a supplier of fabric to the automotive industry and a factory producing plastic cutlery. In 2015, the Town of Wilton acquired it through foreclosure.

By 2019 the mill had undergone the final stages of demolition.

Johannes Bernardus van Loghem. Johannes Bernardus (Han) van Loghem (1881–1940) was a Dutch architect, furniture designer and town planner.

Biography

He was born in Haarlem as the son of a bulb grower and after attending high school at the local HBS, he continued his education at the Polytechnical school there for civic engineering. According to the RKD he studied in Delft during the years 1905–1909 and was influenced by Frank Lloyd Wright and Hendrik Petrus Berlage. After graduation he became an architect in Haarlem where he married the textile artist Berta Neumeier. In 1912 they moved into the house of his own design on the Spaarne river called "Steenhaag".

He received many commissions for city planning, including the projects based on the garden city movement, Rosenhaghe (Haarlem), Betondorp (Amsterdam), Ter Cleef, and Tuinwijk-Zuid (Haarlem), which was built on the other side of the street from his own house. One of his patrons was the local electricity company, for whom he designed 80 aggregate transformer buildings.

From 1917 to 1919 he was a member of the board of directors of the league of Dutch architects and he taught technical theory at the HBO in Amsterdam from 1916–1925. In 1919 he was one of the founders (which included Berlage, Henriette Roland Holst, Clara Wichmann and the artist Theo van Doesburg) of the League of Revolutionary-Socialist Intellectuals. The league only lasted 3 years, possibly because its members were more artistically than politically engaged. 

From 1926 to 1928, Van Loghem worked in Siberia on the urban development of an industrial area in central Siberia, with the mining town of Kemerovo as its center.

In 1928 he established his office in Rotterdam, and joined architecture association 'Opbouw', and would later write for its magazine De 8 & Opbouw. Van Loghem became an ardent advocate of New Objectivity, which he explained in his book Bouwen/Bauen/Bâtir/Building (Amsterdam: Kosmos, 1932), and exemplified through his designs for private houses, such as ''t Kôrnegoar' in Hengelo (1933), 'Knipscheer' in Waalre (1937) and 'Hartog' in Den Haag (1937). 

He died in Haarlem on February 26 1940.

Warp printing. Warp printing is a fabric production method which combines textile printing and weaving to create a distinctively patterned fabric, usually in silk.  The warp threads of the fabric are printed before weaving to create a softly blurred, vague pastel-coloured pattern. It was particularly fashionable in the eighteenth century for summer wear.

The silk and taffeta fabrics produced by this technique have a variety of names, including chiné, Pompadour taffeta (after Madame de Pompadour) and chiné à la branche. Chiné velvet was also possible, although the technique was very difficult and expensive and it was only made in a few places in France in the eighteenth century.

Boring machine (carpentry). A carpenters boring machine is a hand-driven machine to bore holes in beams such in the process of making a mortise or making holes for the wooden pegs which hold mortise and tenon joints together.

History
Before boring machines were invented, carpenters used hand-powered augers to bore holes. Most common were T-handled augers. The shape of the drill bits changed over time, with the spoon bit and shell bit being common before the invention of the spiral or twist bit in 1771 which removes the cuttings as it turns. The exact origin of this invention is not known, but the earliest patent is in the United States in 1830 by J. Beckwith and was as tall as a man and operated by a large wheel from the side.

Boring machines use twist auger bits usually ranging in size from  inch to 2 inches. The machines hold the bit perpendicular (square) to the face of the timber and are operated with both hands while the operator sits on the base to keep the machine from moving. Some machines can be set at an angle. 

American manufacturers included “…Boss, Ajax, Snell Manufacturing Co., Sweet, Jennings, Saunders, R. Ball & co., Roswell Buck, Phillips, Millers Falls, Riley Smith, James Oppenheimer, and the Square Hole Auger Company. Some companies made 10 or 12 different models…”.

Decline in use
Traditional timber framing in North America went into a slow decline after the invention and spread of balloon framing (1832) and what was called plank framing in barn construction in the mid-to-late 19th century. Combined with electrification of hand-held tool carpenters, boring machines became obsolete.

Thompson Bros. Machinery Co. Ltd.. Thompson Bros. Machinery Co. Ltd. was a family owned and operated shipbuilding and repair facility located in Liverpool, Queens County, Nova Scotia. Founded in the early 1900s, it continued to operate under different owners until 2004. The shipyard was notable for its World War II work refitting large numbers of corvettes for the Royal Canadian Navy.

History
The company was founded in the early 1900s and focused on small ship repair as well as small craft construction. It is possible that the company also got into the sales of motor vehicles in the early 1930s. The company saw a large boom during the Second World War the construction of a number of small harbour patrol craft as well as refitting and maintenance large numbers of Royal Canadian Navy ships, notably corvettes. 

Canadian ships refitted at Thompson Brothers included HMCS Sackville, HMCS Ville de Quebec and HMCS Barrie. The yard grew to occupy much of the west bank of the Mersey River (Nova Scotia) in Liverpool's downtown.  After the war, the company became Steel and Engine Products Limited (STENPRO) and worked mainly in fishing boat construction, repair and supply. The yard was eventually bought by Irving Shipbuilding; and closed in September 2004.

Tinkerforge. Tinkerforge is an open-source hardware platform of stackable microcontroller building blocks (Bricks) that can control different modules (Bricklets). The primary communication interface of the building blocks can be extended using Master Extensions. The hardware can be controlled by external programs written in C, C++, C#, Object Pascal, Java, Perl, PHP, Python, Ruby, Shell and VB.NET over a USB, Wi-Fi or Ethernet connection, and running on Windows, Linux and macOS. This non-embedded programming approach eliminates the typical requirements and limitations (development tools, limited availability of RAM and processing power) of conventional embedded software development (such as Arduino). Tinkerforge hardware and software are both open source, and all files are hosted on GitHub.

The computer magazine Chip awarded Tinkerforge 2012 the "Product of the Year" award.

Bricks 

Bricks are  cm circuit boards. They can evaluate measurements, control motors and communicate with other building blocks. Each Brick has a 32-bit ARM microcontroller, a USB connector and connectors for more Bricks and Bricklets.

It is possible to stack several Bricks onto each other. The bottom Brick of such Stacks needs to be a Master Brick.

Bricklets 
Bricklets extend the features of Bricks. They provide means for the input and output of data. Many Bricklets are sensors, but there are also LCD-Bricklets and Bricklets for digital and analog in- and output.

Master Extensions 
Master Extensions extend the communication interfaces of Bricks. Like Bricks, Master Extensions are  cm circuit boards. There are Extensions for Wi-Fi, Ethernet and RS-485. From a programming perspective, the different interfaces are transparent. A stack with Master Extension behaves as if every board in the stack would be directly connected to the PC over a USB connection.

Radioplane XKD4R. The Radioplane XKD4R, known by the company designation RP-70, was an American target drone developed by the Radioplane Division of the Northrop Corporation. Although it was not produced in quantity, it was developed into the successful AQM-38.

Design and development
The XKD4R was an air-launched target drone, powered by a single Aerojet solid-fuel rocket engine which exhausted through nozzles located at the trailing edges of the wing. Constructed largely of molded plastic, it utilized an unconventional control configuration, consisting of three canard control fins located forwards, one on top of and one on either side of the fuselage, and fixed horizontal fins at the rear. An autopilot controlled the drone after launch; at the end of an approximately nine-minute flight, a parachute was deployed for recovery.

Operational history
Conducting its first flight in January 1958, the XKD4R-1 was tested extensively by the United States Navy, launches usually being conducted from McDonnell F3H Demon fighters. Although satisfactory, the RP-70 was not produced; instead, the improved RP-76 was developed, flying in 1959 and being produced for both the U.S. Air Force and Navy, becoming the AQM-38 in 1962.

Carpholite. Carpholite is a manganese silicate mineral with formula Mn2+Al2Si2O6(OH)4. It occurs as yellow clusters of slender prisms or needles. It crystallizes in the orthorhombic system.

The carpholite group includes ferrocarpholite, magnesiocarpholite, vanadiocarpholite, and potassiccarpholite.

Discovery and occurrence
It was first described in 1817 for an occurrence in Horní Slavkov (Schlaggenwald), Karlovy Vary Region, Bohemia. The name derives from Greek karfos for "straw" and lithos for "stone" due to its crystal habit.

Its typical occurrence is in shales that have undergone low grade metamorphism. Associated minerals include sudoite, manganoan garnet, chloritoid and fluorite.
