Tungsram
Tungsram was a manufacturing company located in Hungary and known for their light bulbs and electronics. Established in Újpest (today part of Budapest, Hungary) in 1896, it initially produced telephones, wires and switchboards. The name "Tungsram" is a portmanteau of ''tungsten'' ( ) and ''wolfram'' ( ), the two common names of the metal used for making light bulb filaments. Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and radiotubes, after the American General Electric and RCA companies. History On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted Hungarian patent no. 34541 for the world's first tungsten filament bulb that lasted longer and produced brighter light than a carbon filament. The co-inventors licensed their patent to the company, which came to be named Tungsram after the eponymous tungsten incandescent bulbs, which are still called Tungsram ...

Electrical Filament
An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating a filament until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting.

Hajdúböszörmény
Hajdúböszörmény is a town in northeastern Hungary with a population of approximately 30,000 people. History It is also home to one of the faculties of the University of Debrecen. It has a unique circular plan (like Paris) to the streets that is supposed to have originated as a defense from invasion or attack. Not knowing the plan of the streets a visitor could easily get quite lost only to discover that they were walking in circles for an extended period. Like many smaller towns of Hungary the population even within the city limits generates income as well as household necessities from agriculture and animal husbandry, because of this feature of the local economy, high fences and a cornucopia of smells are very common even within the town core. In 1990s Hajdúböszörmény underwent an economic crisis causing widespread unemployment. Many attribute high unemployment levels to the falling of the Iron Curtain that took place in 1989 and the adjustment period that any economy ...
