Grahame-White Type VI. The Grahame-White Type VI was an early British military aircraft manufactured by the Grahame-White Aviation Company. Only one was built but after an abortive flight development was abandoned.

Design and development
Designed by J.D. North, the Grahame-White Type VI was a pusher configuration unequal-span biplane. 
The tail surfaces were carried on three steel tube booms, with the single upper boom passing through the propeller shaft and the lower pair to the rear of the undercarriage. The propeller was driven by a large-diameter tubular driveshaft and a duplex chain, the propeller being mounted at the top of the rear of the nacelle. There were no centre-section cabane struts, the upper wing being supported solely by the interplane struts. The engine was mounted at the front of the rectangular section nacelle behind a specially made curved radiator, with two crew members seated either side and the pilot seated behind them. 

The control wires for the tail surfaces were carried inside the upper boom, an arrangement credited to Horatio Barber, for whose Aeronautical Syndicate Ltd North had worked. The aircraft was armed with a Colt .30-calibre machine gun on a flexible mounting at the front of the nacelle.

While it was originally intended to be powered by a  Austro-Daimler 6 cylinder inline, it was shown at the 1913 Olympia Aero Exhibition fitted temporarily with a  Austro-Daimler instead.

Only one attempt was made to fly the Type VI. The underpowered aircraft only just managed to clear the hedge at the boundary of the airfield, and made a forced landing in the next field. North went on to design a broadly similar aircraft with a more conventional four-boom mounting for the tail surfaces, the Grahame-White Type XI.

List of aircraft type designators. An aircraft type designator is a two-, three- or four-character alphanumeric code designating every aircraft type (and some sub-types) that may appear in flight planning. These codes are defined by both the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA).

ICAO codes are published in ICAO Document 8643 Aircraft Type Designators and are used by air traffic control and airline operations such as flight planning. While ICAO designators are used to distinguish between aircraft types and variants that have different performance characteristics affecting ATC, the codes do not differentiate between service characteristics (passenger and freight variants of the same type/series will have the same ICAO code).

IATA codes are published in Appendix A of IATA's annual Standard Schedules Information Manual (SSIM) and are used for airline timetables and computer reservation systems. IATA designators are used to distinguish between aircraft types and variants that have differences from an airline commercial perspective (size, role, interior configuration, etc). As well as an Aircraft Type Code, IATA may optionally define an Aircraft Group Code for types and variants that share common characteristics (for example all Boeing 747 freighters, regardless of series).

The following is a partial list of ICAO type designators for a range of multi-engined and turbine aircraft, with corresponding IATA type codes where available.

Communications Processor Module. Communications Processor Module (CPM) is a component of Motorola 68000 family (QUICC) or Motorola/Freescale Semiconductor PowerPC/Power ISA (PowerQUICC) microprocessors designed to provide features related to imaging and communications. A microprocessor can delegate most of the input/output processing (for example sending and receiving data via the serial interface) to the Communications Processor Module and the microprocessor does not have to perform those functions itself. Some input/output functions require quick response from the processor, for example due to precise timing requirements during data transmission. With CPM performing those operations, the main microprocessor is free to perform other tasks.

The CPM features its own RISC microcontroller (Communication Processor), separate from the actual central processing unit IP core. The RISC microcontroller communicates with the core using dual-ported RAM, special command, configuration and event registers as well as via interrupts.

Motorola 68302 Integrated Multiprotocol Processor featured a RISC processor controlled either by a microcode in ROM or by downloadable firmware. Various forms of microcode were shipped for different applications, for example to support Signaling System 7 communications or Centronics parallel interface. Motorola 68360 QUICC was the first design to feature Communications Processor Module, offering microcode for SS7 and ISDN applications. Specifications of the microcontroller programming interface were generally not shipped to customers. It was possible to run 68360 in slave mode and to use only CPM part of the chip, for example in the M68360QUADS-040 board, where 68040 CPU (master) is coupled with 68360 CPM (slave), with CPU of 68360 processor being disabled.

CPM was used later in the PowerQUICC series of PowerPC- and Power ISA-based processors. Early designs, like MPC860, used virtually the same CPM as the previous 68360 QUICC processors.

Typical features of the CPM include:
Medium access control (MAC),
 Communication interfaces with serial communication controllers (SCC), serial management controllers (SMC), Universal Serial Bus, I²C and Serial Peripheral Interface Bus attachment,
 Direct memory access (DMA) circuitry, interrupt controller, time-slot assigner and baud rate generators.

Dimethylamidophosphoric dichloride. Dimethylamidophosphoric dichloride is a chemical used in industrial applications. It is used for synthesizing phosphoramidates as well as tabun, which is used as a chemical weapon.

Safety 
Due to its nature, this chemical is corrosive, flammable, and neurotoxic if ingested or absorbed through the skin. In contact with water, it is expected to give off hydrogen chloride and dimethylamidophosphoric acid vapors.

History 
First synthesis of the substance dates back to turn of the 19th century, when a student of German chemistry professor August Michaelis Ernst Ratzlaff made dimethylamidophosphoric dichloride as well as its diethyl analog for experiments of another PhD student of Michaelis Adolph Schall. He obtained a PhD at University of Rostock with a thesis titled Über die Einwirkung primärer und sekundärer Amine auf Phosphoroxychlorid und Äthoxylphosphoroxychlorid later in 1901. The high toxicity of the substance (as well as the high toxicity of ethyl diethylaminocyanophosphonate, an analog of tabun synthesised by Schall) wasn't noticed at the time, most likely due to the low yield of synthetic reactions used.

ISO 2852. ISO 2852 Stainless steel clamp pipe couplings for the food industry was an international standard that defines a non-permanent sanitary food-grade piping interconnect method, commonly used in the food processing industry and with dairy farm equipment.

The interconnect consists of:
 a lip flange on the ends of pipes with a grooved indentation on the flange.
 a polymer sealing gasket placed between sections of pipe, squeezed between the flanges. This ring has a raised groove on both sides mating with the indentations of the two pipes on either side.
 an enclosing clamp with C-shape clamping sections that cover the outer circumference of the flanges, applying pressure to squeeze the two pipe sections together onto the sealing ring. The clamp also provides structural strength and rigidity to the pipe sections.

The combined lip flange and gasket do not impede the flow of fluids through the piping.

The clamping system may be permanent, using a hose clamp style screw and band, or it may be easily removable using a fold-over hinged clamp assembly.

ISO 2852 is withdrawn as international standard since 31 July 2018.

Other names used in industry 
Companies that supply products according to the specifications of ISO 2852 do not necessarily mention the ISO standard as such, instead referring to the equipment by terms common in the relevant industries or applications. Examples include:

 Tri-Clamp Fittings
 Tri-Clover Fittings
 S-clamp fitting
 Sanitary Fittings
 3A pipe fitting (This terminology includes other types of fittings. "3-A" is a set of standards for cleanability and inspection of dairy equipment, developed by 3-A Sanitary Standards, Inc.)

Frank Sturdy Sinnatt. Frank Sturdy Sinnatt CB FRS (4 May 1880 – 27 January 1943) was a British fuel engineer.

Biography
Sinnatt was born on 4 May 1880 in St. Helier in Jersey, eldest of two brothers and a sister. His father was a journalist, Francis Sinnatt and his mother Sarah Sturdy, from a family of textile manufacturers in Lancashire. The family moved to Manchester when Sinnatt was still a child. There he attended the Central High School and gained a scholarship to enter the Manchester School of Technology in 1897 to study Chemistry. In 1900 he became a demonstrator in Organic Chemistry before being appointed Assistant Lecturer in Applied Chemistry.

Quickly, Sinnatt focussed on the study of coal as a technology. He briefly served with the Special Brigade, in France, in 1915 but returned home injured. By 1918, he set up the Lancashire and Cheshire Coal Research Association, becoming its first director. In 1924, he was appointed Director of Fuel Research at the Department of Scientific and Industrial Research, and went on to be Director in 1931. He supported the project to measure Britain's coal resources (The Coal Survey), becoming its Superintendent in 1924. In addition to his work on establishing the Coal Survey he was still heavily involved with the work of the Fuel Research Station at Greenwich. Around this time, he married his wife, Louise Midgley Badger.

He was made a CB in the 1935 Birthday Honours. He was elected a Foreign Member of the Royal Swedish Academy of Engineering Sciences in 1935 and a Fellow of the Royal Society in 1938. He died of bronchitis in 1943 in Greenwich.

Electronium. The Electronium, created by Raymond Scott, is an early combined electronic synthesizer and algorithmic composition / generative music machine.

Its place in history is unusual, because while in intention it is analogous to the digital algorithmic composition systems that would follow it, it was implemented entirely as an analog electronic machine.

History
Development was begun in 1959, with a workable unit by 1969. Scott, however, never ceased to modify and further develop the device by the time of his death in 1994.

It was one of the very few electronic creations of Scott to be sold to a customer, as he was normally highly secretive about his devices.  A single Electronium machine was sold to Motown Records, following a 1969 meeting between Scott and Motown's Berry Gordy. The initial contract required that Scott visited Motown for three months to teach staff how the machine is used. This culminated in the 1971 hiring of Scott to serve as director of Motown's electronic music and research department in Los Angeles, California, a position that Scott held until 1977. No Motown recordings using Scott's electronic inventions have yet been publicly identified. 

Guy Costa, Head of Operations and Chief Engineer at Motown from 1969 to 1987, said about Scott's hiring:

Scott later said he "spent 11 years and close to a million dollars developing the Electronium."

Much remains to be discovered about the machine's functionality, since detailed documentation on its workings are not currently available, and the single remaining machine is not in working order. 

In a patent application, Scott wrote that "The entire system is based on the concept of Artistic Collaboration Between Man and Machine, (…) The new structures being directed into the machine are unpredictable in their details, and hence the results are a kind of duet between the composer and the machine."

Adding to the difficulty of defining what the Electronium was and how it worked is the fact that it was never finished. Scott continued to develop it during his employment at Motown, and after his dismissal there he carried on working on the machine, stopping only when his deteriorating health abruptly halted him from carrying on, after his first of several strokes.

The Electronium is currently owned by Devo's co-founder and lead singer Mark Mothersbaugh, who has initiated efforts towards its restoration. In 2017, Brian Kehew began working on the restoration of the Electronium, in an effort partially financed by Gotye.

USCGC Cahoone. USCGC Cahoone (WPC/WSC/WMEC-131) was an  of the United States Coast Guard. Launched in 1927, she served until 1968.

Class history 
This class of vessels was one of the most useful and long-lasting in the Coast Guard with 16 cutters still in use in the 1960s. The last to be decommissioned from active service was the  in 1970; the last in actual service was the , which sank after an accidental collision in 1978. They were designed for trailing the "mother ships" along the outer line of patrol during Prohibition. They were constructed at a cost of $63,173 each. They gained a reputation for durability that was only enhanced by their re-engining in the late 1930s: their original 6-cylinder diesels were replaced by significantly more powerful 8-cylinder units that used the original engine beds and gave the vessels 3 additional knots. All served in World War II, but two, the  and , were lost in a storm in 1944. Ten were refitted as buoy tenders during the war and reverted to patrol work afterward.

Cutter history 
Stationed at Stapleton, New York, Cahoone took part in the rescue of survivors of the cruise ship , which burned off New Jersey in 1934. She was at Curtis Bay, Maryland, in 1936 and at Morehead City, North Carolina, in 1937. By 1940 she was at San Pedro, California, where she remained through World War II. From 1946 to 1954, she was at Mount Edgecumbe, Alaska. She was stationed at Galveston, Texas, until 1968.

Arkansas Highways. Arkansas Highways is a magazine that contains updates and information, as well as artistic photographs related to the state of Arkansas and the Arkansas Highway System. It is published bimonthly in Little Rock, Arkansas by the Public Information Office of the Arkansas Department of Transportation (ARDOT).

Description
The magazine began in 1924 by the Arkansas State Highway Commission (now the ARDOT) as an engineering journal dedicated to road construction and maintenance within Arkansas. The publication also featured interviews with staff engineers and commissioners as well as projections for future state highway projects. Updates from each division, department-wide events, and honors for retiring staff are also included. Cartoons and a joke section were formerly part of each magazine.

The magazine began as a monthly publication, but ceased publication from 1933-1952. Volumes were renumbered following resumption in 1953. Publication became quarterly for one year in 1971, was published irregularly through 1974, and became bimonthly from 1975-1999. Arkansas Highways became biannual from 2000-2012, though only one issue was published per year from 2007-2009. In 2013, the magazine resumed bimonthly publication, which continues today. The magazine is given to all staff members and is provided free to the public for no charge upon request.
