Lesher Teal. The Lesher Teal is a home built experimental aircraft that at one point held seven Federation Aeronautique Internationale (FAI) class is C-l.a records for speed and distance.

Design and development
The Teal was designed to beat the Federation Aeronautique Internationale (FAI) class is C-l.a records for speed and distance.

Construction started in 1962. The aircraft was configured as an all-aluminum single-place aircraft with retractable landing gear, powered by a 100 hp Continental O-200 engine driving a 64-inch Hartzell ground-adjustable propeller.  By 28 April 1965, the airframe was complete.  On that day, Lesher made the aircraft's first flight at Willow Run Airport.  That August, he flew Teal to the 1965 EAA Fly-In in Rockford, Illinois, where he won an award from the EAA for his achievements.

Operational history
After two years of testing the Teal, Lesher flew the aircraft, on 22 May 1967, to a new 500 km closed-course Class C1a speed record of 181.55 mph.  On 30 June 1967, he set a new 1,000 km closed-course speed record of 169.20 mph and on 220 October 1967, he set a new 2,000 km closed-course speed record of 141.84 mph.

On 6 May 1968, while flying Teal near Ann Arbor, he experienced a loss of power.  Not being able to make it to a nearby airport, he made an emergency landing in a field.  The airplane was badly damaged, but he was unhurt. After rebuilding Teal, on 9 September 1970, he set a new Class C1a closed-circuit distance record of 1554.29 miles.  Later, on 29 September 1973 he set a new Class C1a 3 km speed record of 173.101 mph and the next day he set a new 15–25 km speed record of 169.134 mph.  Finally, on 2 July 1975, he set a new Class C1a record for distance in a straight line by flying 1,835.459, flying from Florida to Arizona.  He continued to fly Teal for many more years, but never made any more record attempts.  For his record-breaking flights, he won the FAI's Louis Bleriot Medal four times and was inducted in the Michigan Aviation Hall of Fame in 1988.

The Teal was donated to the EAA Airventure Museum in 2002.

SLEM-1. The SLEM-1 (Self Loading Experimental Model 1) was a semi-automatic battle rifle. The weapon is gas-operated, semi-automatic and has a 10-round magazine.

Development
Fabrique Nationale's Belgian design team, led by Dieudonné Saive, worked in Britain throughout the war, having escaped the German occupation of Belgium in 1940. They worked for the Small Arms Design Department which had been moved from Enfield to the drill hall at Cheshunt, about five miles away. When the British General Staff decided in 1944 that the future British infantry cartridge would be the 8×57mm IS, already in production for the Besa machine gun and generally more suitable to autoloading weapons than rimmed .303 British cartridge, the Belgian team designed the SLEM-1 (Self Loading Enfield Model 1).

When the 8×33mm Kurz was tested everything changed and the British set up the Small Arms Calibre panel that led to the  and  rounds. The Belgian team then redesigned the SLEM to become the prototype FAL, first in 8mm Kurz and then in .280 British. The extractor groove of the .280 was changed to meet US specification and became the .280/30.

After the war, the SLEM was further developed into the FN Model 1949 and subsequently the FN FAL.

Augusta–Aiken Railway and Electric Corporation. The Augusta–Aiken Railway and Electric Corporation was an electric interurban railroad that operated between Augusta, Georgia and Aiken, South Carolina. Once completed in 1902 the railroad remained in operation until it was abandoned in 1929.

History 

Augusta, Georgia hosted an electric street railway network after 1890 and an intricate horsecar network prior to that year. A short spur reaching out from Augusta, bridging the Savannah River, and into South Carolina had already been in place since 1891.

Around the turn of the century, James U. Jackson and other land developers began construction on the luxurious Hampton Terrace Hotel in North Augusta. Simultaneously the trolley was extended to the resort hotel and further surveyed for extension to Aiken, South Carolina. The railroad reached Aiken in 1902 and began operations that same year. The Hampton Terrace Hotel had its own spur track used to deliver coal and freight, and remained an important fixture of the route until it burned to the ground in 1916.

Freight services over the line came in the form of an express car and electric boxcab locomotives. Most freight traffic consisted of coal delivered to the Hampton Terrace Hotel or to the numerous cotton mills along the line.

As with many other interurban railroads in the United States, the advent of the automobile helped bring about the end of the Augusta - Aiken trolley in 1929. Augusta's own streetcar network would be out of service by 1937, replaced by intercity buses.

Tanaka Seisakusho. was the first company established by Tanaka Hisashige, one of the most original and productive inventor-engineers during the Tokugawa / Edo period.

Overview 
Established in July 1875, it was the first Japanese company to manufacture telegraph equipment. It also manufactured switches, and miscellaneous electrical and communications equipment.

The company was inherited by Tanaka's adopted son, and later became half of the present Toshiba company. Several people who worked at Tanaka Seisakusho or who received Tanaka's guidance at a Kubusho (Ministry of Industries) factory later became pioneers themselves. These included Miyoshi Shōichi who helped Fujioka make the first power generator in Japan and to establish a company, Hakunetsusha to make bulbs; Oki Kibatarō, the founder of the present Oki Denki (Oki Electric Industry); and Ishiguro Keizaburō, a co-founder of the present Anritsu. 

After the demise of the founder in 1881 Tanaka Seisakusho became partly owned by General Electric and expanded into the production of torpedoes and mines at the request of the Imperial Japanese Navy, to become on the largest manufacturing companies of the time. However, as the Navy started to use competitive bids and then build its own works, the demand decreased substantially and the company started to lose money. The main creditor to the company, Mitsui Bank, took over the insolvent company in 1893 and renamed it Shibaura Seisakusho (Shibaura Engineering Works).

Interlake (dinghy). The Interlake is an American planing sailing dinghy that was designed by Francis Sweisguth in 1932, as a one-design racer and first built in 1933.

The boat design was commissioned by the Sandusky Sailing Club. Sweisguth had already designed the Star keelboat and the Interlake was designed specifically for the conditions found on Lake Erie and in particular on Sandusky Bay.

Production
For a time the design was built by Customflex, initially in Toledo, Ohio and later in Whitehouse, Ohio in the United States, but commercial production by Customflex has now ended. In 2023, licensing to build Interlakes was assumed by Beacon Composites in Creedmoor, North Carolina.

The boat's class club, the Interlake Sailing Class Association, also offers free plans for download in PDF format to allow amateur construction of the design.

Design
The Interlake is a recreational sailboat, originally built predominantly of wood, fiberglass construction has been allowed by the class rules since 1955. The fiberglass boats have balsa cores for the hull and the decking. The boat has a fractional sloop rig, a spooned raked stem, an angled transom, a rounded, transom-hung, fiberglass rudder controlled by a tiller and a retractable fiberglass centerboard, operated by a winch with a 10:1 mechanical advantage. It displaces .

The boat has a draft of  with the centerboard extended and  with it retracted, allowing beaching or ground transportation on a trailer.

For sailing the design has foam flotation, mainsail boom roller reefing, a boom vang and mainsheet traveler with a bridle. The boat may be equipped with spinnaker of  and hiking straps. The mast is supported by a forestay and shrouds, but no jumper stays or backstay. There is stowage provided under the foredeck.

The design has a Portsmouth Yardstick racing average handicap of 89.9 and is normally raced with a crew of two or three sailors.

Operational history
The boat is supported by an active class club, the Interlake Sailing Class Association, which organizes races and offers free plans for the design.

In a 1994 review Richard Sherwood wrote that the "Interlake was designed for Sandusky Bay, Ohio, known for its short chop. She will plane fairly readily. The bow and sheer are classic, and the forward flare throws spray down, keeping her dry. She was originally built in wood, but fiberglass was allowed in 1955. Interlake is one of the older one-design classes in the United States."

LCVP (Australia). Since 1993, the Royal Australian Navy has operated four Australian-designed and built Landing Craft, Vehicle and Personnel (similar in size and concept to the World War II LCVP) from the landing ship, heavy , replenishment oiler , LSD HMAS Choules and Pacific support vessel ADV Reliant. These aluminum craft were built by Geraldton Boat Builders and can carry up to 36 personnel or a Land Rover with a half-ton trailer. They are maintained for the RAN by the firm DMS Maritime. As of 2022, T4 and T5 are carried by ADV Reliant.

In July 2024 the RAN ordered two light landing craft to operate from the auxiliary ship ADV Reliant instead of LCVPs. The new craft will be larger and faster than the LCVPs.

Stillwaterite. Stillwaterite is a palladium arsenide mineral which has a general formula of Pd8As3.  Stillwaterite was first discovered in the Banded and Upper zones of the Stillwater igneous complex in Montana, United States, and has been reported in the Lac-des-Iles area of Ontario, Canada.  Outside of North America, this rare mineral has been found in northern Finland.

Symmetry
Stillwaterite has hexagonal symmetry, meaning that it has four crystallographic axes: three are horizontal axes of equal length, and the fourth is a vertical axis of different length.

Optical properties
Because it is opaque, stillwaterite is most commonly viewed under reflected light, appearing light creamy gray in color.  It is weakly anisotropic in air, displaying dark gray to brownish gray color.  In oil immersion, it shows distinct anisotropy with brownish black color and a blue to yellow-brown tinge.  Hexagonal minerals such as stillwaterite are referred to as uniaxial crystals because they have only one direction, along the optic axis, in which light is not reoriented.

Significance
Since its discovery in the mid-1970s, Stillwaterite has been studied to better understand the characteristics of complex mineral assemblages of gold, silicates, and other palladium arsenides with which it is associated. Minerals containing palladium can have economic significance, and are mined for use in industrial and commercial applications.

Thomson TO7. The Thomson TO7, also called Thomson 9000 is a home computer introduced by Thomson SA in November 1982, with an original retail price of 3750 FF.
By 1983 over 40000 units were produced. About 84 games were released for the TO7.

The TO7 is built around a 1 MHz Motorola 6809 processor. ROM cartridges, designed as MEMO7, can be introduced through a memory bay.
The user interface uses Microsoft BASIC, included in the kit cartridge. The keyboard features a plastic membrane, and further user input is obtained through a lightpen.
Cooling is provided by a rear radiator. 
A standard television can serve as a monitor using a RGB SCART (Peritel) connector, with a resolution of 320x200 (with 2 colors for each 8 x 1 pixels).

The TO7 prototype, called Thomson T9000, was developed in 1980. The differences regarding the production model are a different startup menu and buggier BIOS.

Specifications
The Thomson TO7 runs on a Motorola 6809 processor clocked at 1 MHz and features 22 KB of RAM (8 KB for the user, 8 KB used as video memory and 8K x 6 bits color memory) and 20KB of ROM (4KB for the monitor and 16KB on MEMO7 cartridges).

As common on home computers designed to be connected to an ordinary TV screen, the 320 x 200 pixels active area doesn't cover the entire screen, and is surrounded by a border. 
Graphics were limited to 8 colours (generated by combination of RGB primaries) with proximity constraints (2 colors for each 8 x 1 pixel area).
The video output is RGB on a SCART connector, with the refresh rate being 625-line compatible 50Hz.

Audio featured a single channel sound generator with five octaves. A "game expansion" was capable of four channel, six octaves sound.

The keyboard has 58 keys and includes arrow keys.

Besides cartridges, the machine used cassette tapes for file storage.

Thomson TO7/70

An upgraded version, the Thomson TO7/70, was released in 1984 with an introductory price of 3590 FF. 
It was used as an educational tool in French schools under the Computing for All plan, where the TO7/70 could be used as a used a "nano-machine" terminal for the "Nanoréseau" educational network.

Among improvements RAM was increased to 64 KB  - "70" on the version name stands for 64+6 (64KB RAM + 6KB ROM). The 6809 processor was replaced by a Motorola 6809E and the color palette was extended from 8 to 16 colors. 

Graphics were similar to the Thomson MO5 and generated by a Motorola MCA1300 gate array capable of 40×25 text display and a resolution of 320 x 200 pixels with 16 colours (limited by 8 x 1 pixel colour attribute areas). The colour palette is 4-bit RGBI, with 8 basic RGB colours and a intensity bit (called P for "Pastel") that controlled saturation ("saturated" or "pastel"). 

Software developed for the TO-7 can be run on the TO-7/70, but the reverse is not possible. At least three games were released for the TO7/70.

PlusCal. PlusCal (formerly called +CAL) is a formal specification language created by Leslie Lamport, which transpiles to TLA+. In contrast to TLA+'s action-oriented focus on distributed systems, PlusCal most resembles an imperative programming language and is better-suited when specifying sequential algorithms. PlusCal was designed to replace pseudocode, retaining its simplicity while providing a formally-defined and verifiable language. A one-bit clock is written in PlusCal as follows:

-- fair algorithm OneBitClock {
  variable clock \in {0, 1};
  {
    while (TRUE) {
      if (clock = 0)
        clock := 1
      else 
        clock := 0    
    }
  }
