Traffolyte, sometimes spelled Traffolite, was a brand name for multi-layered phenolic plastic sheets suitable for engraving. Each layer was a different colour so engraved letters or shapes would be a different colour from the unengraved portions. Thus it could be used for name tags, labels and signs.
The material dates back to 1927, when it was first produced by Metropolitan-Vickers Electrical Ltd. at their Trafford Park factory in Manchester, UK for transformer labels. The complete business was sold to De La Rue Insulation Ltd [1] in 1945; De La Rue exited this business in the early 1960s. There are a large number of companies manufacturing bi- and tri-layer phenolic engraving stock and it has become a generic term; no record of its having been a registered trademark in the United States or UK has been found.
Traffolyte signs and labels are cheap to produce, and were very popular in the past. However, phenolic dust is now recognized as a health hazard and so precautions must be taken during label production.
Bakelite, formally polyoxybenzylmethyleneglycolanhydride, is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909.
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding.
Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs.
Plywood is a composite material manufactured from thin layers, or "plies", of wood veneer that have been stacked and glued together. It is an engineered wood from the family of manufactured boards, which include plywood, medium-density fibreboard (MDF), oriented strand board (OSB), and particle board.
Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain. The surface is covered with ink by rolling over the surface with an ink-covered roller (brayer), leaving ink upon the flat surface but not in the non-printing areas.
Aquatint is an intaglio printmaking technique, a variant of etching that produces areas of tone rather than lines. For this reason it has mostly been used in conjunction with etching, to give both lines and shaded tone. It has also been used historically to print in colour, both by printing with multiple plates in different colours, and by making monochrome prints that were then hand-coloured with watercolour.
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity.
Associated Electrical Industries (AEI) was a British holding company formed in 1928 through the merger of British Thomson-Houston (BTH) and Metropolitan-Vickers electrical engineering companies. In 1967 AEI was acquired by GEC, to create the UK's largest industrial group. A scandal that followed the acquisition is said to have been instrumental in reforming accounting practices in the UK.
Amontillado is a variety of sherry wine characterised by being darker than fino sherry, but lighter than oloroso sherry. Amontillado wine is named after the Montilla municipality, in Andalusia, Spain, where the style of sherry originated in the 18th century; commercially, the name "Amontillado" is used as a measure of colour to label any style of sherry that lay between the categories of fino and oloroso. In American literature, Amontillado sherry features in the title of the short story "The Cask of Amontillado" (1846), by Edgar Allan Poe.

Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world.
Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellers for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965.
Conway Stewart & Company Ltd is a British manufacturing company of writing implements, founded in 1905 by Frank Jarvis and Thomas Garner in London. The company became notable for its fountain pens, although it also produced ballpoint pens. Conway Stewart was placed in receivership in 2014, with its stocks and assets acquired by Bespoke British Pens Ltd., which owns the rights to the brand since then.
Scenes of Canada is the fourth series of banknotes of the Canadian dollar issued by the Bank of Canada. It was first circulated in 1970 to succeed the 1954 Canadian Landscape series and was followed by the 1986 Birds of Canada banknote series. This was the last series to feature a $1 bill, which was replaced by a $1 coin known as the loonie in 1987, although both the $1 bill and the loonie were produced concurrently for 21 months, from June 1987 to April 1989.
Brunswick Wharf Power Station was a coal- and oil-fired power station on the River Thames at Blackwall in London. The station was planned from 1939 by Poplar Borough Council but construction only started in 1947 after the Second World War. It was decommissioned in 1984, and the site was redeveloped.
'Seahorses' is the name used to refer to the United Kingdom high value definitive postage stamps issued during the reign of King George V.
Harrison and Sons was a major worldwide engraver and printer of postage stamps and banknotes.
Stipple engraving is a technique used to create tone in an intaglio print by distributing a pattern of dots of various sizes and densities across the image. The pattern is created on the printing plate either in engraving by gouging out the dots with a burin, or through an etching process. Stippling was used as an adjunct to conventional line engraving and etching for over two centuries, before being developed as a distinct technique in the mid-18th century.
Gilles Demarteau or Gilles Demarteau the Elder was an etcher, engraver and publisher who was active in Paris for his entire career. He is one of the persons to whom has been attributed the invention of the crayon manner of engraving. He is recognized as playing an important role in the development of this engraving technique. He was one of the key reproductive engravers and publishers of the work of François Boucher.
MetroVick electric vehicles were a range of battery electric road vehicles produced by the heavy engineering company Metropolitan-Vickers between 1934 and 1944. The company was renamed Metropolitan-Vickers in 1919, and entered the electric vehicle market in 1934, when they bought up the General Vehicle Company of Birmingham. They inherited the designs for the Gordon range of models, and continued to service and supply parts for the G.V. Electric vehicles. Their main sales seem to have been of light vans and dairy vehicles, in three sizes, which they promoted through a series of exhibitions. During the Second World War, they experienced difficulties in obtaining raw materials, and the number of vehicles that could be built was severely restricted by quotas. Production of the range ceased entirely in 1944, and when hostilities ceased, they sold the electric vehicle business to Brush in 1945.
