Associated Weavers. Associated Weavers International Group is currently a Belgian textile manufacturing company. The company head office and production plant is located in Ronse.

History
A company with the name "Associated Weavers" was founded in Bradford, West Yorkshire, England and run by the Abrahams family. By the early 1970s the site in Tong employed 2,500 people and was the world's largest producer of Axminster woven carpets and Europe's largest producer of tufted printed carpets. At that time the company was principally led by managing director Jack Collins, commercial director David Croft and the marketing and design director Michael Kelly.

In 1964, the American carpet manufacturer Trend Mills started producing carpet in Ronse, Belgium.

In 1969, an American concern Champion International took over the plant in Ronse and in 1973 the British Associated Weavers in Bradford. The production of tufted broadloom carpet was moved to the location in Ronse. Although at one time the company produced one in seven of all carpets bought in the UK, it was not a widely known brand name.

Due to a rapid contraction of the UK carpet sector the Bradford site was sold in the early 1980s; and in 1984 Champion International decided to withdraw from the carpet industry altogether. The result was a management buy-out, in 1984, followed by the establishment of the holding company "Associated Weavers International".

In 1990 the company acquired Prado, which was founded in 1909 as Tissage Van de Wiele as a weaving mill for furnishing fabrics, Prado makes both woven and tufted wall-to-wall carpet and rugs.

In 1997 the company registered on the Brussels Stock Exchange as the first Belgian carpet manufacturer.

In 1998 the company acquired a factory in Liberec, Czech Republic for mainly labour-intensive work such as finishing carpets and rugs.

In 2001 it took over the French company, Balsan, specialising in broadloom carpet for contract applications such as hotels, public buildings, schools, etc.

Since 2010, Associated Weavers International is part of Belgotex International Group.

Change of strategy
Associated Weavers had been pursuing for years a volume strategy in the medium-low segment of the market and was seeking in vain to achieve satisfying business results.

The strategy was adjusted by a heavy emphasis on the development of trendy, value-for-money products brought into market via innovative marketing concepts. Investments were made in a complete rebranding, with the new logo integrating the tagline “Carpet your life” as the prime feature.

The slogan “Carpet your life” is no less than an invitation to the end consumer to choose a carpet from among a series of new collections offered in an inviting “Butterfly” display per colour, based on five universal life styles.

Possible involvement in pollution by PFAS
Belgian newspapers published in September 2021 news about the pollution from PFAS in Ronse, linking it to the presence of textile industries in the town.

ROBUSTA. ROBUSTA (Radiation on Bipolar for University Satellite Test Application) is a nano-satellite scientific experiment developed by the University of Montpellier students as part of a Centre National d'Études Spatiales (CNES) call for student projects in the field of orbital systems.

The satellite is a Cubesat, the name given to a series of nano-satellites developed as part of student projects. The ROBUSTA mission is to check the deterioration of electronic components, based on bipolar transistors, when exposed to in-flight space radiation. The results of the experiment will be used to validate a new radiation test method proposed by the laboratory.

Implementation of the project 
The duration of the ROBUSTA project is 6 years, beginning in 2006. The satellite was launched on 13 February 2012 on the Vega rocket's maiden flight, and reentered in the atmosphere in February 2015. An anomaly within the battery recharge system resulted in the loss of the satellite after a few days.

Staff 
Teams from several sites, coordinated by the Centre Spatial Universitaire Montpellier-Nîmes worked together. These teams are spread over several sites:

  The mechanical design was done by the IUT GMP of Nîmes;
  Energy management was conducted by IUT GEII of Nîmes;
  The ground segment and communication cards are supported by the IUP PGII Montpellier.
  The controller card was done by Polytech Montpellier and  IUT GEII Montpellier.
  The payload is managed by the EEA department of the University of Montpellier.

Caudron C.270 Luciole. The Caudron C.270 Luciole ("Firefly") was a sporting, touring and trainer aircraft produced in France in the 1930s, derived from the C.230.

Design and construction
It was a conventional biplane with single-bay, unstaggered wings of equal span. The pilot and a single passenger sat in tandem open cockpits. It featured a fabric-covered fuselage in place of the C.230's wooden one, and other refinements including revised control surfaces and undercarriage, and an improved and simplified wing-folding mechanism.

Operational history
The type proved immensely successful, with over 700 machines built in the decade leading up to World War II. Of these, 296 were purchased by the French government for its pilot training programme, the Aviation Populaire. Many examples saw wartime service as liaison aircraft, and those surviving the conflict saw postwar use as glider tugs in the Ecole de l'Air.

On film 

 20th Century Fox used two Lucioles in their 1966 film The Blue Max. These had the rear seat converted into a machine-gun position so that they look like British observation planes. One of these survives on the American registry.
 United Artists used one Luciole for their film Von Richthofen and Brown (released in 1971).
 EMI Films used one Luciole for the 1976 film Aces High, this time reconverted to look like a British Avro 504.

Stinson Voyager. The Stinson Voyager was an American light utility monoplane built during the 1940s by the Stinson Aircraft Company.

Development
First developed as the Stinson HW-75 and marketed as the Model 105 in 1939, the design was a high-wing three-seat braced monoplane powered by either a 75-hp (63.4-Kw) Continental A-75 or an 80-hp (67.7-Kw) Continental A-80-6. This was developed into the Model 10, introduced in 1940, powered by a Continental A-80 piston engine. The Model 10 introduced a wider cabin as well as an improved standard for the interior and finish. In 1941 the Model 10 was followed by the Model 10A, powered by a Franklin 4AC-199 engine and the Model 10B with a Lycoming GO-145. The 10A was the last of the series, but the first to be called "Voyager", a name that was retained for the post-war Stinson 108.

Six Model 10s were evaluated by the United States Army Air Forces (USAAF) as the YO-54. The unsuccessful tests led Stinson to design an all-new aircraft designated Model 76, later known as the L-5 Sentinel.

A number of Model 105s and Model 10As were impressed into USAAF service as the AT-19 (later L-9). However, the AT-19 designation has not been verified.

After World War II, the type was developed as the Model 108, the prototypes being converted Model 10As.

Sodium tetrafluoroborate. Sodium tetrafluoroborate is an inorganic compound with formula NaBF4. It is a salt that forms colorless or white rhombic crystals and is soluble in water (108 g/100 mL) but less soluble in organic solvents.

Sodium tetrafluoroborate is used in some fluxes used for brazing and to produce boron trifluoride.

Preparation
Sodium tetrafluoroborate can be prepared by neutralizing tetrafluoroboric acid with sodium carbonate or sodium hydroxide.
NaOH + HBF4 →   NaBF4  +  H2O
Na2CO3  +  2 HBF4  →  2 NaBF4  +  H2O  +  CO2

Alternatively the chemical can be synthesized from boric acid, hydrofluoric acid, and sodium carbonate:

2H3BO3 + 8HF + Na2CO3 → 2NaBF4 + 7H2O + CO2

Reactions and uses
On heating to its melting point, sodium tetrafluoroborate decomposes to sodium fluoride and boron trifluoride:
NaBF4   →   NaF  +  BF3
It is a source of tetrafluoroborate anion, which is used in organic chemistry for the preparation of salts.  Sodium tetrafluoroborate can be used for synthesis of ionic liquids, where tetrafluoroborate is the anion.

Nitronium tetrafluoroborate. Nitronium tetrafluoroborate is an inorganic compound with formula NO2BF4. It is a salt of nitronium cation and tetrafluoroborate anion. It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO3. As such, it must be handled under water-free conditions. It is sparsely soluble in many organic solvents.

Preparation

Nitronium tetrafluoroborate can be prepared by adding a mixture of anhydrous hydrogen fluoride and boron trifluoride to a nitromethane solution of nitric acid or dinitrogen pentoxide.

Applications

Nitronium tetrafluoroborate is used in organic synthesis as an electrophilic nitrating agent and a mild oxidant.

DigiMorph. Digital Morphology (DigiMorph), part of the National Science Foundation Digital Libraries Initiative, creates and shares 2D and 3D visualizations of the internal and external structure of living and extinct vertebrates, and a growing number of 'invertebrates.'

The information core for the DigiMorph library is generated using a high-resolution X-ray computed tomographic (X-ray CT) scanner at the University of Texas at Austin. This instrument is comparable to a conventional medical diagnostic CAT scanner, but with greater resolution and penetrating power. The device uses X-rays to take images of thin slices through solid objects, such as bone and rock. Hundreds to thousands of slices are stacked up to create a three-dimensional model of the object, allowing researchers to peer inside without damaging it.

As of 2007, the DigiMorph library contains over a terabyte of imagery of natural history specimens that are important to education and research efforts. The DigiMorph library site now serves imagery, optimized for Web delivery, for over 475 specimens contributed by more than 125 collaborating researchers from natural history museums and universities worldwide.

The CT scanner is housed at the Jackson School of Geosciences at the University of Texas at Austin and is operated by scientists in The University of Texas High-Resolution X-ray Computed Tomography Facility (UTCT), a designated NSF-supported Multi-User Facility.

Chase (lighting). A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string.  With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.

Chase lights (or chaser lights) are often associated with the marquee signs of some movie theaters, and have also been used as a common element of television game show sets.

Creating a chase effect
In order to achieve a chase "strip lights" are most often used, especially when used in "theatrical" applications.

Similar design is used in computing, where it is known as "marching ants".

Several separate circuits of lights (called channels) are needed to create a chase effect which is a simulation of motion achieved by turning these circuits ON and OFF in sequence. 
The standard is 3 or 4 channels. 
For 4 channels the lights are wired with one common and 4 different feeds. 
Light #1 is wired with lights #5 & 9 & 13, etc. (+4); 
Light #2 is wired with lights #6 & 10 & 14, etc. (+4);
Light #3 is wired with lights #7 & 11 & 15, etc. (+4);
Light #4 is wired with lights #8 & 12 & 16, etc. (+4).

The most common 4 channel chase which is seen in a theater Marquee perimeter lighting and other lighting animation applications consists of 4 channel wired light bulbs and an electronic chaser.
The electronic chaser turns channel #1 ON while all the other Channels remain OFF. Then after an adjustable period of time it turns OFF channel #1 while turning ON channel #2, then turn OFF channel #2 while turning ON channel #3, then turn OFF channel #3 while turning ON channel #4, then repeat.
This creates the illusion that the lights are moving in one direction.
Some digital lighting chasers are made to do the above described single light chase pattern along with other combinations of Turning ON and OFF of the light to create different sequences like forward light chase, backward light chase, bouncing, dark chase (1 channel OFF while all 3 others ON), etc...
Also, more than 4 channel chasers are used to create more effects and to animate illuminated objects.

Chase circuits using LEDs are commonly built by electronics hobbyists with timer (such as the 555 timer IC) and counter (such as the 4017, which allows up to 10 channels) integrated circuits.
