Marconi Company
The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.

Mullard 5-10
The Mullard 5-10 was a circuit for a valve amplifier designed by the British valve company, Mullard in 1954 at the Mullard Applications Research Laboratory (ARL) in Mitcham Surrey UK, part of the New Road factory complex, to take advantage of their particular products. The circuit was first published in Practical Wireless magazine. The amplifier featured five valves and an output of 10 watts - hence '5-10'. Of those valves, one was a full-wave rectifier (an EZ80 or EZ81), one was a pre-amplifier pentode EF86 and one a double-triode ECC83 as phase splitter. The power amplification was handled by a pair of EL84 working in push-pull configuration. The frequency response of the circuit was from 40Hz to 20,000Hz with less than 0.2% THD. In 1959 Mullard published its famous booklet "Mullard Circuits for Audio Amplifiers" covering a range of amplifier and pre-amplifier circuits using valves developed within the Receiving Valve Development Department at the New Road factory.

Engineering Magazines
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific ...

Wireless
Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazines Established In 1913
A magazine is a periodical publication, generally published on a regular schedule (often weekly or monthly), containing a variety of content. They are generally financed by advertising, purchase price, prepaid subscriptions, or by a combination of the three. Definition In the technical sense a ''journal'' has continuous pagination throughout a volume. Thus ''Business Week'', which starts each issue anew with page one, is a magazine, but the '' Journal of Business Communication'', which continues the same sequence of pagination throughout the coterminous year, is a journal. Some professional or trade publications are also peer-reviewed, for example the '' Journal of Accountancy''. Non-peer-reviewed academic or professional publications are generally ''professional magazines''. That a publication calls itself a ''journal'' does not make it a journal in the technical sense; ''The Wall Street Journal'' is actually a newspaper. Etymology The word "magazine" derives from Arabic , th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science And Technology Magazines Published In The United Kingdom
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek man ...

Ivor Catt
Ivor Catt (born 1935) is a British electronics engineer known principally for his alternative theories of electromagnetism. He received a B.A. degree from Cambridge University, and has won the ''Electronic Design'' magazine's "best product of the year" award on 26 October 1989, after £16 million funding. Biography Ivor Catt was born in England and grew up on an RAF airbase in Singapore. He left the country, along with his mother and sister, just before the Japanese invasion in 1942. He did his National Service stationed in Germany. He won a State Scholarship in mathematics and then studied engineering at Trinity College, Cambridge. Wafer scale integration Catt developed and patented some ideas on '' Wafer scale integration'' (WSI) in 1972, and published his work in ''Wireless World'' in 1981, after his articles on the topic were rejected by academic journals. The technique, christened ''Catt Spiral'', was designed to enable the use of partially faulty integrated chips (called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PSI Comp 80 (computer)
In 1979, the British magazine Wireless World published the technical details for a "Scientific Computer". Shortly afterward the British firm Powertran used this design for their implementation, which they called the PSI Comp 80. It was sold in the form of a kit of parts for a cased single-board home computer system. The system was based on a Z80 Microprocessor addressing a mixture of 8 KB of system RAM and EPROM, plus 2 KB of Video RAM. It used a National Semiconductor MM57109N as a mathematical co-processor to speed up calculations. The monochrome Video Display Controller could simultaneously display combinations of 32 lines of 64 characters, and 128 x 64 resolution graphics by either displaying a normal character or a "pseudo graphics" character, with pixel blocks in a 2x2 matrix. A technique similar to the one used in the TRS-80 - It could later be expanded to a higher resolution, although never to colour. Ahead of its time, it incorporated a number crunching coprocessor a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nascom
The Nascom 1 and 2 were single-board computer kits issued in the United Kingdom in 1977 and 1979, respectively, based on the Zilog Z80 and including a keyboard and video interface, a serial port that could be used to store data on a tape cassette using the Kansas City standard, and two 8-bit parallel ports. At that time, including a full keyboard and video display interface was uncommon, as most microcomputer kits were then delivered with only a hexadecimal keypad and seven-segment display. To minimize cost, the buyer had to assemble a Nascom by hand-soldering about 3,000 joints on the single circuit board. Later on, a pre-built, cased machine named Nascom 3 was available; this used the Nascom 2 board. History The history of Nascom starts with the history of John A. Marshall. Marshall was the "& Son" of "A Marshall & Son (London) Ltd", an electronic component retailer whose adverts were a regular feature in hobby electronics magazines from as early as 1967. Marshall was a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teletext
A British Ceefax football index page from October 2009, showing the three-digit page numbers for a variety of football news stories Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel. Teletext was created in the United Kingdom in the early 1970s by John Adams, Philips' lead designer for video di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
