A ground effect vehicle (GEV) is one that attains level flight near the surface of the Earth, made possible by a cushion of high-pressure air created by the aerodynamic interaction between the wings and the surface known as ground effect. Also known as a wing-in-ground-effect (WIG) vehicle, flarecraft, sea skimmer, ekranoplan, or wing-in-surface-effect ship (WISE), a GEV can be seen as a transition between a hovercraft and an aircraft. The International Maritime Organization (IMO) has classified the GEV as a ship.[1] A GEV differs from an aircraft in that it cannot operate without ground effect, so its operating height is limited relative to its wingspan.

In recent years a large number of different GEV types have evolved for both civilian and military use. However, these craft are not in wide use.
Small numbers of experimental vehicles were built in Scandinavia just before World War II. By the 1960s, the technology started to improve, in large part due to the independent contributions of Rostislav Alexeev in the Soviet Union[2] and German Alexander Lippisch, working in the United States. Alexeev worked from his background as a ship designer whereas Lippisch worked from his own background as an aeronautical engineer. The influence of Alexeev and Lippisch is still noticeable in most GEV vehicles seen today.

The Soviet Central Hydrofoil Design Bureau (CHDB), led by Alexeev, was the center of ground-effect craft development in the USSR; in Russian, the vehicle came to be known as an ekranoplan (Russian: экранопла́н, French: ecran "screen" + Russian: plan "plane", from эффект экрана effekt ekrana). The military potential for such a craft was soon recognised and Alexeev received support and financial resources from Soviet leader Nikita Khrushchev.

Some manned and unmanned prototypes were built, ranging up to eight tons in displacement. This led to the development of the "Caspian Sea Monster", a 550-ton military ekranoplan.[3] Although it was designed to travel a maximum of 3 m (9.8 ft) above the sea, it was found to be most efficient at 20 m (66 ft), reaching a top speed of 300 kn (350 mph; 560 km/h) (400 kn (460 mph; 740 km/h) in research flight).

The Soviet ekranoplan program continued with the support of Minister of Defense Dmitri Ustinov. It produced the most successful ekranoplan so far, the 125-ton A-90 Orlyonok. These craft were originally developed as very high-speed military transports, and were based mostly on the shores of the Caspian Sea and Black Sea. The Soviet Navy ordered 120 Orlyonok-class ekranoplans. But this figure was later reduced to fewer than thirty vehicles, with planned deployment mainly in the Black Sea and Baltic Sea fleets.

A few Orlyonoks served with the Soviet Navy from 1979 to 1992. In 1987, the 400-ton Lun-class ekranoplan was built as a missile launcher. A second Lun, renamed Spasatel, was laid down as a rescue vessel, but was never finished.

Minister Ustinov died in 1985, and the new Minister of Defense, Marshal Sokolov, effectively stopped the funding for the program. Only three operational Orlyonok-class ekranoplans (with revised hull design) and one Lun-class ekranoplan remained at a naval base near Kaspiysk.

The two major problems that the Soviet ekranoplans faced were poor longitudinal stability and a need for reliable navigation.

Since the fall of the Soviet Union, ekranoplans have been produced by the Volga Shipyard[4] in Nizhniy Novgorod.

GEV developed since the 1980s have been primarily smaller craft designed for the recreational and civilian ferry markets. Germany, Russia, and the United States have provided most of the momentum with some development in Australia, China, Japan, and Taiwan. In these countries, small craft up to ten seats have been designed and built. Other larger designs as ferries and heavy transports have been proposed, though none have gone on to further development.

After the collapse of the Soviet Union, smaller ekranoplans for non-military use have been under development. The CHDB had already developed the eight-seat Volga-2 in 1985, and Technologies and Transport developed a smaller version by the name of Amphistar.

In Germany, Lippisch was asked to build a very fast boat for Mr. Collins from Collins Radio Company in the USA. He developed the X-112, a revolutionary design with reversed delta wing and T-tail. This design proved to be stable and efficient in ground effect and even though it was successfully tested, Collins decided to stop the project and sold the patents to a German company called Rhein Flugzeugbau (RFB) which further developed the model.

Tandem flarecraftHanno Fischer took over the works from RFB and created his own company called Fischer Flugmechanik. Their two-seat Airfisch 3 and their later model that seats 6 passengers have been a successful design. This craft, the FS-8, was to be produced by a Singapore-Australian joint venture called Flightship.[5] The company no longer exists, and the ship is out of production. An ongoing research project in collaboration with the university of Duisburg-Essen, involves the development of the Hoverwing.[6]

Günther Jörg in Germany, who had also been working on Alexeev’s first designs, and was familiar with the challenges of GEV design, developed a GEV with two wings in a tandem arrangement, the Jörg-II. It was the third, manned, tandem airfoil boat,named "Skimmerfoil", which was developed during his consultancy period in South Africa. It was a simple and low-cost design, but has not been produced to date. The consultancy of Dipl. Ing. Günther Jörg was founded with a fundamental knowledge of Wing in Ground Effect physics, as well as results of fundamental tests under different conditions and designs that began in 1960. In 1984, Günther Jörg received the "PHILIP MORRIS AWARD". In 1987, the Botec Company was founded
Current development
A number of companies have been heavily lobbying governments for development funding to pursue research and development of GEV craft exceeding 500 tonnes. The current worldwide trend in the decline in military research and development spending since the end of the Cold War era has not been conducive to funding the development of GEV craft. The perceived development risk is very high due to the untested nature of the technology and the uncertainties in the development process, operational costs and performance outcomes. GEVs have been suggested as the solution to a number of possible operational roles, with heavy lift being the most appealing attributes. GEVs have been proposed as an alternate to the very large aircraft needed to fulfill these transportation goals. The US Air Force report "Airlift 2025"[citation needed] looked at using GEVs as heavy-lift platforms with the capabilities of insertion into remote locations, long range and good survivability. In the report, GEVs were cited as inappropriate for the intended use as there was a need for another method of transport from the coast to the required destination. Another study by the US Navy’s "Strategic Studies Group XVI"[citation needed] also looked at the possibility of using small GEVs as insertion and extraction craft or naval gunfire teams. Also discussed were the advantages of using WIG craft for transoceanic cargo craft, where their increased speed would reduce resupply times by at least 60%.

Civilian roles for GEVs have been heavily promoted at a number of conferences held since 1993. GEVs have been suggested as recreational craft, small to large ferries and large transport craft. A number of small companies have emerged designing and constructing GEVs for these purposes. A number of large Russian and US companies have gone as far as the preliminary design of a number of concept GEVs mainly for the transport and heavy lift market.

Theoretical research into GEVs’ aerodynamics, ground effect and WIG craft stability has proceeded at a number of research centres. Performance enhancement of takeoff and landing distances as well as methods to increase sea state limitations have been analysed on prototypes and with model tests. Research continues into the determination of the most efficient platform configuration.

Besides the development of appropriate design and structural configuration, special automatic control systems and navigation systems are also being developed. These include special altimeters with high accuracy for small altitude measurements and also lesser dependence on weather conditions. After extensive research and experimentation, it has been shown that "phase radio-altimeters" are most suitable for such applications as compared to laser, isotropic or ultrasonic altimeters.[7]

Even today R&D activities are being carried out for such vehicles in several countries, including Russia, USA, China, Germany, UK and Australia. Other future projects include the horizontal take-off and horizontal landing of Aerospace Planes (ASP) using ekranoplans.

In Russia, the reduced defense spending has forced GEV manufacturers to look for potential sales in the civil market. A number of designs have been proposed for heavy transport while a small GEV, the Amphistar, has been produced in limited numbers.
In 2007, Vice premier and defense minister Sergey Ivanov announced at a meeting of the naval board: "A federal targeted program will be created according to which Nizhniy Novgorod will manufacture wing-in-ground-effect vehicles".[citation needed] The designers of the Beriev aviation scientific and technical complex responded immediately and have promised to create the new ultra-heavy Be-2500 transport amphibious airplane. The Be-2500’s takeoff weight will be about 2,500 tonnes with a useful payload near 1,000 tonnes. Wing span is 125 meters, length is 115 meters and height is 29 meters. Cruising speed at altitude is 770 kilometers per hour, and in ground effect is 450 kilometers per hour. For comparison: wing span of the Boeing 747 is 64.4 meters, the airplane’s length is 70.6 meters, and height is 19.4 meters.
Additionally, the civilian Arctic Trade and Transport Company (Арктическая Торгово-Транспортная Компания) produces "Aquaglide" ekranoplans, small craft capable of transporting five people including the pilot.
In China, GEVs are being researched to fulfill a number of roles in the Chinese military and commercial use. The China Academy of Science & Technology Development and China Ship Scientific Research Centre (CSSRC) started GEV project in 1980. The 702 design bureau and 708 design bureau designed a number of small prototypes. In 1995, the first commercial ferry Tianyi-1 project started. In 1998, the first Tianyi-1 prototype is tested. In 2000, the model is for commercial sale in China. Currently a larger prototype Tianxiang-2 has been completed and a 50 seater Tianxiang-5 is under development.
In the USA, a number of small companies have designed and tested a number of small ferry and recreational craft. The L-325 has gone into limited production and is for commercial sale in the U.S. Aerocon has proposed the development of a large GEV transport craft but does not appear to have gained sufficient funding for the project.
In Germany, the military interest of the 1970s has decreased. As a result the German company RFB has shifted its emphasis from GEV development. The former technical director Mr. Fischer founded a company Fischer Flugmechanik which has designed and built craft for the recreational market, their most notable development being the Airfish recreational craft. Fischer Flugmechanik, in conjunction with Techno Trans research institute, have been sponsored by the German Ministry of R&D to develop a second generation GEV. This has resulted in the development of the two-seat prototype, HW-2VT.
The leading German company for Tandem Airfoil WIG craft is the Botec GmbH, located near Frankfurt.
In 1984 Phillip Morris Company awarded Dipl. Ing. W. Günther Jörg as the winner of the competition for Future Traffic Systems. Botec Company was founded in 1987 under the leadership of the Tandem Airfoilboat specialist Dipl. Ing. Günther W. Jörg . Dipl. Ing. Günther W. Jörg and his team have developed a large number of WIG craft for the civilian market, some of which have gone into limited production. The development of those TAF (Tandem Airfoil Flairboat) includes a number of craft in different designs and sizes. Botec GmbH has developed Tandem Airfoil Flairboats suitable for leisure boat applications and for commercial applications. Up to 2005, 16 Tandem Airfoil Flairboats had been built and successfully tested according to all rules and regulations. Dipl. Ing. Günther W. Jörg and his team have provided a lot of ideas scheduled for further applications in the commercial transportation sector.

In Japan, GEV technology has been analyzed in order to gain a leading position in the fast ferry design and construction market. A number of research craft have been prototyped and tested but none have proceeded onto development.
In Australia, there are a number of small enterprises, companies and individuals, the most newsworthy being the Rada and Seawing companies. These companies were established in the early 1990s with the goal of developing small commuter and recreational craft. None of the craft built by these companies progressed beyond prototype development. Neither of these companies are functioning at present, however the principals are still active in GEV development. In 2004, a company from Australia known as Sea Eagle emerged, and worked with China’s CSSRC to develop a civilian range of Class B Wing Effect Craft. Currently the Craft is flying in China.
Sea EagleNew Zealand mechanic Rudy Heeman successfully adapted a 2-person hovercraft [8] as a wing in ground effect vehicle in 2010.

One of the problems that have delayed the development of these craft is the classification and legislation to be applied. IMO has studied the application of rules based on the International Code of Safety for High-Speed Craft (HSC code) which was developed for fast ships such as hydrofoils, hovercraft, catamarans and the like. The Russian Rules for classification and construction of small type A ekranoplans is a document upon which most GEV design is based. However in 2005, the IMO classified the WISE or GEV crafts under the category of ships.

The International Maritime Organization recognizes three classes of ground effect craft:

Type A cannot operate out of ground effect.
Type B can jump to clear obstacles by converting kinetic energy (speed) into potential energy (height), but cannot maintain flight without the support of the ground effect.
Type C are certified as aircraft, with the ability to operate safely and efficiently out of ground effect.
Advantages and disadvantages
A ground effect craft may have better fuel efficiency than an equivalent aircraft flying at low level due to the close proximity of the ground, reducing lift-induced drag. There are also safety benefits for the occupants of the craft in flying close to the water as an engine failure will not result in severe ditching. However, this particular configuration is difficult to fly even with computer assistance. Flying at very low altitudes, just above the sea, is dangerous if the craft banks too far to one side while making a small radius turn.

A takeoff must be into the wind, which in the case of a water launch, means into the waves. This creates drag and reduces lift. Two main solutions to this problem have been implemented. The first was used by the Russian Ekranoplan program which placed engines in front of the wings to provide more lift. The Caspian Sea Monster had eight such engines, some of which were not used once the craft was airborne. A second approach is to use some form of an air-cushion to raise the vehicle most of the way out of the water, making take-off easier. This is used by German Hanno Fischer in the Hoverwing (successor to the Airfisch ground effect craft), which uses some of the air from the engines to inflate a skirt under the craft in the style of a sidewall hovercraft.

View of the tanker ‘Gomphina’ and the cargo ship ‘Hemsefjell’ at Manor Quay, March 1948 (TWAM ref. DS.JLT/4/PH/1/655/1/4). ‘Gomphina’ was launched by J.L. Thompson & Sons at North Sands on 14 October 1947.

This set celebrates the achievements of the famous Sunderland shipbuilding firm Joseph L. Thompson & Sons. The company’s origins date back to 1846 when the firm was known as Robert Thompson & Sons. Robert Thompson senior died in 1860, leaving his second son Joseph Lowes Thompson in control. In 1870 the shipyard completed its last wooden vessel and was then adapted for iron shipbuilding.

By 1880 the firm had expanded its operations over much of North Sands and in 1884 completed the construction of Manor Quay, which served as fitting out and repair facilities. For many years in the late nineteenth century the yard was the most productive in Sunderland and in 1894 had the fourth largest output of any shipyard in the world.

The Depression affected the firm severely in the early 1930s and no vessels were launched from 1931 to 1934. However, during those years the company developed a hull design giving greater efficiency and economy in service. During the Second World War the prototype developed by Joseph L. Thompson & Sons proved so popular that it was used by the US Government as the basis of over 2,700 Liberty ships built at American shipyards between 1942 and 1945.

After the War the North Sands shipyard went on to build many fine cargo ships, oil tankers and bulk carriers. Sadly the shipyard closed in 1979, although it briefly reopened in 1986 to construct the crane barge ITM Challenger.

English translation:
"Koblenz has a powerful argument. It’s called The Devourer."

I wasn’t familiar with Koblenz vacuum cleaners, so looked into it — a bit of history from the company’s website:
Koblenz is an international manufacturer of domestic and industrial floor care products, voltage regulators, battery backups and washers.
The company was founded on July 15, 1959 as a manufacturer of voltage regulators, motors and pumps. During the 1960´s, the company added vacuum cleaners and shampoo/polishers to its product line.
In 1961 Koblenz developed its first vacuum cleaner, with an all-metal chassis and a single stage motor. The introduction of this vacuum cleaner in foreign markets was a success due to the ruggedness and durability of the product design. In 1968 Koblenz introduced the first line of Rug Shampooers and Floor Polishers. In 1972 the company started manufacturing washing machines. In 1998 the company introduced a Total Floor Care System to satisfy the every day needs of consumers worldwide.
Koblenz has over 2000 full time Employees including a complete engineering staff, state of the art test labs, and prototype facilities. All this operates in a main manufacturing plant of over 300,000 square feet.
During the fall of 2000 Koblenz acquired Hoover´s Mexican operation adding 10,000 sq. ft. to its manufacturing plant.
Koblenz currently exports product to over 27 countries throughout the world including Japan, Australia, New Zealand, Saudi Arabia, Europe, Central and South America.

Hotchkiss 864 (1937)

Cascais, Portugal

in Wikipedia

Hotchkiss cars were made between 1903 and 1955 by the French company Hotchkiss et Cie in Saint-Denis, Paris. The badge for the marque showed a pair of crossed cannons, evoking the company’s history as an arms manufacturer.

The company’s first entry into car making came from orders for engine components such as crankshafts which were supplied to Panhard et Levassor, De Dion-Bouton and other pioneering companies and in 1903 they went on to make complete engines. Encouraged by two major car distributors, Mann and Overton of London and Fournier of Paris, Hotchkiss decided to start making their own range of cars and purchased a Mercedes Simplex for inspiration and Georges Terasse, previously of Mors, was taken on as designer.

Early cars

The first Hotchkiss car, a 17 CV four-cylinder model, appeared in 1903. The engine of the 20 CV type C was heavily based on the Mercedes Simplex except that wherever possible it used ball bearings rather than plain ones (including the crankshaft) and except the Hotchkiss drive. Six-cylinder models, the types L and O followed in 1907.
The ball bearing engines lasted until the 30CV type X of 1910. In that same year Hotchkiss moved into a smaller car market with the 2212cc type Z.
With the outbreak of World War I, the factory turned to war production and a subsidiary plant was opened in Coventry, England. Car production resumed in France 1919 with the pre war types AD, AD6, AF and AG.

Inter war production

After an attempt to enter the luxury market with the AK, which did not get beyond the prototype stage, the company decided on a one model policy and introduced the Coventry designed AM in 1923. Later that year the Coventry plant was sold to Morris. Henry Ainsworth (1884–1971) and A.H. Wilde who had run it, moved to Paris to become general manager and chief engineer of the car division respectively.

In 1926 construction of the new factory in the Boulevard Ornano was completed and Hotchkiss bought a steel pressing company allowing in-house manufacture of bodies. The one model policy lasted until 1929 when the six-cylinder AM73 and AM80 models were announced.

The AM models were replaced by a new range in 1933 with a new naming system. The 411 was an 11CV model with four-cylinder engine, the 413 a 13CV four and the 615, 617 and 620 were similar six-cylinder types. The 1936 686, which replaced the 620, was available as the high-performance Grand Sport and 1937 Paris-Nice with twin carburettors and these allowed Hotchkiss to win the Monte Carlo Rally in 1932, 1933, 1934, 1939, 1949 and 1950.

Second World War

The armament side of the company and the body stamping plant were nationalised in 1936 by the Front Populaire government. The car company in 1937 took over Amilcar. With re-armament speeding up they also started making military vehicles and light tanks. When France declared war, in September 1939, Hotchkiss were sitting on a army order for 1,900 H35 and H39 tanks powered by six-cylinder motors of respectively 3.5 and 6 litres capacity, and at the time of the German invasion in May 1940 they were still working through the order.[1] However, as the military situation deteriorated the decision was taken, on 20 May 1940, to abandon the Saint-Denis plant which by now was fully concentrated on war production.[1] There was a disorderly evacuation, initially towards Auxerre and then Moulins and then further towards the south, as employees desperately tried to keep information on the military production out of the hands of the Germans.[1] However, the national capitulation implicit in the signing of the armistice on 22 June left these efforts looking somewhat irrelevant, and most of the employees drifted back in the ensuing weeks.[1] Two exceptions were the Commercial Director, Jacques Jacobsen and the English born General Director, Henry Ainsworth, both of whom managed to avoid capture and to leave France.[1] During the war, like many businesses in the occupied (northern) zone, the company was obliged to work for the occupiers and was engaged in the repair of military vehicles.[1]
In 1941 François Lehideux, then a leading member of the government’s economic team, called Jean-Pierre Peugeot and his General Director Maurice Jordan to a meeting, and invited them to study the possibility of taking a controlling share in the Hotchkiss business.[1] The suggestion from Lehideux derived from a German law dated 18 October 1940 authorising the confiscation of businesses controlled by Jews.[1] The Peugeot business itself had been operating, grugingly, under overall German control since the summer of 1940. In any event, in July 1942 Peugeot took a controlling share in the Hotchkiss business and towards the end of 1942 the names of Peugeot and Jordan were listed as members of the Hotchkiss board.[1] There is no evidence of any attempt to combine the operations of the two businesses, however: after the war Peugeot would relinquish their holding in Hotchkiss.
With liberation in 1944, Ainsworth returned and production restarted in 1946 with the pre-war cars, a light truck and a tractor.

Post war models

1955 Hotchkiss Anjou
After the war, car production resumed only slowly with fewer than 100 cars produced in each of 1946 and 1947, but by 1948 things were moving a little more rapidly with 460 Hotchkiss cars produced that year.[2] This volume of output was wholly insufficient to carry the company, although truck production was a little more successful with more than 2,300 produced in 1948,[2] and it was support from the truck volumes and from the Jeep based M201 that enabled the company to stagger on as a car producer slightly more convincingly than some of France’s other luxury car makers, at least until the mid 1950s. The cars that represented the business in the second half of the 1940s were essentially the company’s prewar designs. The 2,312 cc four-cylinder car was now branded as the Hotchkiss 864 while the six-cylinder car was badged as the Hotchkiss 680 with a 3,016 cc engine or as the Hotchkiss 686 with the 3,485 cc engine.[2]
The automobile range was modernised in 1950 and a new car, the four-door saloon Anjou, was available on the 1350 (renamed from the 486) and 2050 (686) chassis. The Anthéor cabriolet was added in 1952. In 1948 Hotchkiss had bought the rights to the Grégoire front-wheel-drive car and this car entered production in 1951 but was expensive. Sales in general were falling and in 1950 Ainsworth retired. The Peugeot family sold their interest in the company. Coupé and cabriolet versions of the Hotchkiss-Grégoire were announced in 1951, but sales did not improve, and production stopped in 1952 after only 247 were made.

Merger and closure

Hotchkiss merged with Delahaye in 1954 to become Société Hotchkiss-Delahaye, but car production stopped in 1955 to be replaced by licence built Jeeps. In 1956 the company was taken over by Brandt, a household appliance maker, to become Hotchkiss-Brandt, who were again taken over in 1966 by Thomson-Houston. Military vehicles were made until 1967 and trucks until 1971.

KItchenAid Artisan – ND0_5479

The idea of a stand mixer was formulated by Herbert Johnson, an engineer working at the Hobart Corporation. He had been inspired after seeing a baker mix dough, and thought that there must be a better way of doing the task. Development began, in 1914, the model "H" mixer was launched for industrial work. The U.S. Navy ordered mixers for two new Tennessee-class battleships, the California and the Tennessee, as well as the U.S. Navy’s first dreadnought battleship, the South Carolina. In 1917, Hobart stand mixers became standard equipment on all U.S. Navy ships, prompting development to begin on the first home models.
The first machine to carry the KitchenAid name was the 10 quart C-10 model, introduced in 1918 and built at Hobart’s Troy Metal Products subsidiary in Springfield, OH.[2] Prototype models were given to the wives of factory executives, and the product was named when one stated "I don’t care what you call it, but I know it’s the best kitchen aid I’ve ever had!" They were initially marketed at the farmhouse kitchen and were available in hardware stores.[3] But owing to the difficulty in convincing retailers to take up the product, the company recruited a mostly female sales force, which sold the mixers door-to-door.[1] The C-10 machine was also marketed heavily towards soda fountains and small commercial kitchens, and was also sold under the FountainAid and BakersAid model names.[4]

In 1922, KitchenAid introduced the H-5 mixer as its new home-use offering.[5] The H-5 mixer was smaller and lighter than the C-10, and had a more manageable five quart bowl. The model "G" mixer, about half the weight of the "H-5", was released in August 1928.[6] In the 1920s several other companies introduced similar mixers, with the Sunbeam Mixmaster becoming the most popular among consumers until the 1950s.

KitchenAid mixers remained popular, with the factory selling out of products each Christmas in the late 1930s. Having shut down production for the duration of the Second World War, the factory started up again in 1946 with production moving to Greenville, Ohio, to expand capacity.

The product range expanded beyond stand mixers for the first time in 1949, with dishwashers being introduced.[3]

In 1985, the company purchased the Chambers Company to incorporate its range of cookers into the KitchenAid brand.[1] After being cleared by a Federal appeals court in January 1986, Whirlpool Corporation were cleared to purchase KitchenAid after initial complaints regarding competition from dishwasher manufacturers White Consolidated Industries and Magic Chef were dismissed.[8] Refrigerators were added to the product line later in 1986.[1] The company used the popularity of celebrity chefs during the late 1980s to seize the chance to expand its customer range. In 1988, retailer Williams-Sonoma was opening new stores across the United States and released a cobalt blue stand mixer for the company. Although the retailer had been carrying KitchenAid products since 1959, the new stores introduced the mixers to a wider range of home cooks. This combined with a change in marketing strategy for KitchenAid, which resulted in a doubling of brand awareness over the course of the following three years.

KitchenAid began manufacturing blenders and other small appliances in the mid-1990s. The brand was further promoted by sponsoring the PBS show Home Cooking, and by introducing the mixers to television chefs such as Julia Child and Martha Stewart. Following the success with William-Sonoma, specific point of purchases were set up in department stores such as Kohl’s and Macy’s. Specific color mixers were released for specific retailers or to benefit charities, such as a pink mixer released to raise funds for breast cancer research or mixers sold at Target stores being available in that company’s signature shade of red. The ProLine range of appliances was launched in 2003 with an initial six month exclusivity agreement with Williams-Sonoma
