6204th Photo Mapping Flight. The 6204th Photo Mapping Flight was a United States Air Force unit that fought in the Korean War.   The unit was attached to Far East Air Forces Fifth Air Force

In mid-July 1950, the 6204th Photo Mapping Flight, located at Clark AB, Philippines, deployed the Flight's two RB-17 aircraft complete with combat crews and maintenance personnel to Johnson AB, Japan. The FEAF deployment order specified that the two RB-17 aircraft be equipped with normal armament insofar as practicable, so as not to interfere with the photographic capability of the aircraft. This posed a problem for the Flight since the RB-17s had been flying peacetime missions and were not equipped for combat. However, the 6204th found the necessary gunners and equipment, made the modifications to the aircraft, and by late August 1950 the detachment began flying photo-mapping missions over Korea. By the end of November 1950, it had photographed the entire North Korean area at least once and re-photographed some areas as far north as weather conditions permitted. By early December the detachment returned to Clark AB and resumed the flight's mapping program in the Philippine area.

Vickers Valparaiso. The Vickers Valparaiso was a British light bomber biplane of the 1920s. It was designed by Vickers as a development of its Vixen for export, being sold to Portugal and Chile.

Development and design

The Vickers Valparaiso was a derivative of the Vixen I for export purposes. It was renamed Valparaiso to distinguish it from the Vixen, which as it used classified government equipment, was unavailable for export. Two versions were available, one powered by the same Napier Lion as the Vixen, known as the Type 93 Valparaiso I, while the Type 92 Valparaiso II was powered by the Rolls-Royce Eagle engine  Other than their engines, the Valparaisos were very similar to the Vixen I, both being single-bay biplanes with wooden wings and steel tube fuselages. Both versions were purchased by Portugal, which ordered ten Valparaiso Is and four Valparaiso IIs, with the Lion-powered aircraft to serve as reconnaissance bombers and the lower powered Valparaiso IIs to serve as advanced trainers. In 1928, Portugal decided to license-produce a modified Valparaiso powered by a Gnome et Rhône Jupiter radial engine, and a single Valparaiso was modified by Vickers to use the Jupiter, followed by the production of 13 aircraft, designated Type 168 Valparaiso III by OGMA (Oficinas Gerais de Material Aeronáutico).

Operational history

The Portuguese aircraft proved to be successful in service, with two carrying out a long distance tour from Portugal to its African colonies of Angola and Mozambique and back in 1928, with the success of the aircraft resulting in the decision to license-produce the Valparaiso III. The radial-powered Valparaisos also proved successful in Portuguese service, remaining operational until 1943, finally being replaced by Westland Lysanders.

A single Valparaiso I (actually the prototype), was sold by Vickers to Chile in 1924. It was successful in Chilean service, resulting in an order for a further 18 modified aircraft, which reverted to the original name of Vixen, as the Vixen V.

Bücker Bü 182 Kornett. The Bücker Bü 182 Kornett ("Ensign") was a single-seat advanced trainer developed in Germany for Luftwaffe service shortly before the outbreak of World War II.

A single-seat low-wing cantilever monoplane, it was intended to give student pilots some experience with an aircraft with performance approaching that of a contemporary fighter, and could carry practice bombs. Production was shelved at the outbreak of war, and only about four examples were ever constructed, all of them destroyed around 1943.

Development 
The last aircraft designed by Anderson, the Bü 182 Kornett, of which only three were built, found no support in the Air Ministry of the Reich, even though it combined technical progress and low-cost. The Bü 182 Kornett was a highly innovative model, fitted with a low-priced high-performance engine, that would have made a good trainer for the Luftwaffe.

Buhl-Verville CA-3 Airster. The Buhl-Verville CA-3 Airster (also known as the J4 Airster, after its engine), was a utility aircraft built in the United States in 1926, notable as the first aircraft to receive a type certificate in the US, (i.e. A.T.C. No. 1) issued by the Aeronautics Branch of the Department of Commerce on March 29, 1927. It was a conventional single-bay biplane with equal-span unstaggered wings and accommodation for the pilot and passengers in tandem open cockpits.  Marketed for a variety of roles including crop-dusting, aerial photography, and freight carriage, only a handful were built, some with water-cooled engines as the CW-3, and others with air-cooled engines as the CA-3 . One CA-3 placed second in the 1926 Ford National Reliability Air Tour.

1926 Ford Air Tour, piloted by Louis Meister, and another (designated the CA-3A) placed third in the 1927 Air Derby, piloted by Nick Mamer. One CW-3 and one CA-3 each were evaluated by the United States Army as trainers, but neither were purchased.

SVI-738. The Spectravideo SVI-738 X'Press is an MSX1 compatible home computer manufactured by Spectravideo from 1985. Although compatible with the MSX 1.0 standard, it incorporates several extensions to the standard (80-column display, serial RS-232, built-in 3.5" floppy drive); many are hardware-compatible with the MSX 2.0 standard but the system as a whole is not, leading to it being referred to as an "MSX 1.5" computer.

Along with the Sony HB-101, Canon V-8, Casio MX-10 and Hitachi MB-H1, it was a portable computer based on the MSX standard, hence the title "X'Press". It came packaged with its own carrying bag in addition to the manuals, booklets and software (CP/M 2.2 and MSX-DOS 1.0) a disk containing a special demonstration program featuring an astronaut flying about on the screen, demonstrating the computer's graphic capabilities and listing facts about the computer's ROM and RAM sizes.

Along with the disk drive and integrated serial port, what stood out the most was the use of the graphics chip specified by the MSX-2 standard, although the use of only 16 KB of VRAM allowed you to add only an 80 column mode. This, together with bugs in the first model's design (Konami SCC-sound based cartridges do not work or have bad sound) are among the reasons for the "MSX 1.5" moniker.

It ran Microsoft Disk BASIC 1.0 from ROM when turned on if no disk or a non-autoexecutable disk was inserted.

Marketing

The computer was marketed mainly in Europe, Australasia and the Middle East. In Poland, 2000 units were marketed in 1986 by Centralna Składnica Harcerska at a price of 440 000 PLZ (the average salary for 18 months at that time). This was the only MSX computer to be sold in official network in communist Poland. This version of the SVI-738 was equipped with an altered keyboard and ROM in order to provide Polish-specific characters. It could also be found in schools in Finland .  In Spain, it was initially distributed by Indescomp until the creation of a Spanish subsidiary. In the United Kingdom, it was sold for £399.95. The SVI-738 was also sold in the United States.

Swageless terminal. In 1973 Sta-Lok launched the swageless terminal system  for wire rope at the London Boat Show.

The swageless terminal can be fitted by using hand tools, unlike a swage terminal which requires a special press, roller die or rotary hammer machine to crimp it onto a wire.  This makes them very useful if the wire assembly must be made-up on site. A swageless terminal will work under constant loading and variable shock loading, making it stronger than the wire rope.

Regardless of manufacturer the basic principle of operation is the same.  The cable has its outer layers wrapped around a metal cone,  with the rope's core running through a hole in the middle of the cone. The assembly sits inside a conical outer body.  When the cable is in tension, the action is such that the cone and wire are drawn further into the conical bore of the outer body resulting in a large reaction load.  This load grips the wire and prevents further movement.  

As with swage terminals, swageless terminals are available with a variety of different attachment methods; fixed clevis forks, toggling clevis forks, eyes and threaded studs (for insertion in a turnbuckle barrel).

Swageless terminals can be used for terminating cables for applications in the construction, defense and marine industries.  

A swageless terminal can be removed and re-used, unlike a swaged terminal. This makes them very popular in the marine industry as they enable a quick repair to be made to a damaged cable while out at sea.  Removing them from the wire end also allows anything which the cable has been threaded through (headstay furler) to be removed for servicing, re-threaded and the fitting re-attached.

There are several manufacturers of swageless fittings including Sta-Lok (who invented the swageless system), Hi-MOD and Norseman-Gibb.

Swaged socket. A swage terminal is a product used to terminate wire. A swaging machine is used to terminate the wire. The wire is passed into a deep hole in the swage terminal which is then pressed onto the terminal by applying force. This type of product is used in the architectural and marine industries. There are many companies globally who manufacture swage terminals, including Sta-Lok.

Carr index. The Carr index (Carr's index or Carr's Compressibility Index) is an indicator of the compressibility of a powder. It is named after the scientist Ralph J. Carr, Jr.
 
The Carr index is calculated by the formula , where  is the freely settled bulk density of the powder, and  is the tapped bulk density of the powder after "tapping down".  It can also be expressed as .

The Carr index is frequently used in pharmaceutics as an indication of the compressibility  of a powder.  In a free-flowing powder, the bulk density and tapped density would be close in value, therefore, the Carr index would be small. On the other hand, in a poor-flowing powder where there are greater interparticle interactions, the difference between the bulk and tapped density observed would be greater, therefore, the Carr index would be larger. A Carr index greater than 25 is considered to be an indication of poor flowability, and below 15, of good flowability.

Another way to measure the flow of a powder is the Hausner ratio, which can be expressed as .

Both the Hausner ratio and the Carr index are sometimes criticized, despite their relationships to flowability being established empirically, as not having a strong theoretical basis. Use of these measures persists, however, because the equipment required to perform the analysis is relatively cheap and the technique is easy to learn.

Philips VG-8020. The VG-8020 was Philips' third MSX computer introduced in 1984, after the VG-8000 and the VG-8010 computers.

With a price of 2990 Fr, the machine was MSX1 standard compatible, had a real keyboard (instead of a chiclet keyboard like its predecessors) and a printer port (missing on the previous models). 

The VG-8020 was  manufactured by Kyocera and featured a Zilog Z80A microprocessor clocked at 3.56 MHz, 64KB of RAM, 16KB of VRAM, two cartridge slots and two joystick ports. 

The machine came with MSX BASIC 1.0 in ROM and graphics were provided by a Texas Instruments TMS9929A, with RF and composite video outputs. Sound was generated by a General Instruments AY-3-8910 chip.

It was replaced by the VG-8220, a MSX2 compatible machine.

Models 
The computer was marketed in several variants:

 Philips VG-8020/00 (PAL, QWERTY keyboard, 1984)

Hardware compatibility list. A hardware compatibility list (HCL) is a list of computer hardware (typically including many types of peripheral devices) that is compatible with a particular operating system or device management software. The list contains both whole computer systems and specific hardware elements including motherboards, sound cards, and video cards. In today's world, there is a vast amount of computer hardware in circulation, and many operating systems too. A hardware compatibility list is a database of hardware models and their compatibility with a certain operating system.

HCLs can be centrally controlled (one person or team keeps the list of hardware maintained) or user-driven (users submit reviews on hardware they have used).

There are many HCLs. Usually, each operating system will have an official HCL on its website.
