British Valve Association
The British Radio and Valve Manufacturers' Association (BVA) was a 20th-century cartel of vacuum tube A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It ... (valve) manufacturers in the United Kingdom of Great Britain and Northern Ireland (UK) that was designed to protect their interests from foreign competition. This cartel dictated (among other things), the price of valves (vacuum tubes) and how they were numbered. The numbering scheme was supposedly designed to make it difficult to identify American equivalents, which were typically half the retail price in their home country; however American types manufactured in the UK by companies such as Brimar sold at the same price as their UK counterparts due to the BVA's insistence. All manufacturers eventually published their own lists o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartel
A cartel is a group of independent market participants who collaborate with each other as well as agreeing not to compete with each other in order to improve their profits and dominate the market. A cartel is an organization formed by producers to limit competition and increase prices by creating artificial shortages through low production quotas, stockpiling, and marketing quotas. Jurisdictions frequently consider cartelization to be anti-competitive behavior, leading them to outlaw cartel practices. Cartels are inherently unstable due to the temptation by members of the cartel to cheat and defect on each other by improving their individual profits, which may lead to falling prices for all members. The doctrine in economics that analyzes cartels is cartel theory. Cartels are distinguished from other forms of collusion or anti-competitive organization such as corporate mergers. Advancements in technology or the emergence of substitutes can undermine cartel pricing power, leadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum Tube
A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...

Trade Associations Based In The United Kingdom
Trade involves the transfer of goods and services from one person or entity to another, often in exchange for money. Economists refer to a system or network that allows trade as a market. Traders generally negotiate through a medium of credit or exchange, such as money. Though some economists characterize barter (i.e. trading things without the use of money) as an early form of trade, money was invented before written history began. Consequently, any story of how money first developed is mostly based on conjecture and logical inference. Letters of credit, paper money, and non-physical money have greatly simplified and promoted trade as buying can be separated from selling, or earning. Trade between two traders is called bilateral trade, while trade involving more than two traders is called multilateral trade. In one modern view, trade exists due to specialization and the division of labor, a predominant form of economic activity in which individuals and groups con ...
