EMI Stories 476 to 570
Another EMC resource from EMC Standards EMI Stories 476 to 570 Helping you solve your EMC problems 9 Bracken View, Brocton, Stafford ST17 0TF T:+44 (0) 1785 660247 E:[email protected] EMI Stories 476 to 570 476) Another lightning story The Broward County (Florida) Civil Defense office had a 180 foot radio tower that was several years old before it was finally hit by lighting (this was many years ago). It turns out the tower was not grounded. The lightning came down the heliax coaxial cables, about 2 inches in diameter (no cm back then), into the building. One of the (vacuum tube, remember those?) VHF radios looked like the speaker grille was hit by a fist from behind. The CD director's telephone was melted on the desk. All the electrical outlets were burned and the air-raid siren relay was welded ‘on’. The siren activated and would not turn off. The only person in the office was a secretary who knew nothing about electricity. I think she must have aged 10 years in 2 seconds that day. I was in high school at the time and came to realize at a tender age that there is no such thing as a ‘lightning protector’. (Copied from: “Another lightning story” in the thread “Danger and Power of Lightning”, posted on [email protected] by Douglas C. Smith, 2nd April 2002.) 477) Black Hawk helicopter crashes In the mid 1980s, the US Army experienced 29 crashes of its UH-60 Black Hawk helicopters, at least five of which were believed to be due to RFI. -

Logistics requirements fall into three broad, overlapping categories: Immediate, Mid- Term, and Sustainment requirements. These categories commence and terminate at different times depending on the theater of operations, with Immediate being the most time sensitive and Sustainment the least. They are: 1. Immediate: War materiel needed as soon as combat forces are inserted into a theater of operations in order to enable them to attain a credible defensive posture. 2. Mid-Term: War materiel, which strengthens in-place forces and permits expansion to higher force levels. 3. Sustainment: War materiel needed to maintain combat operations at the desired tempo. US strategic transport systems divide into two categories: airlift and sealift. -

Advanced Technologies Group (ATG) SkyCat Peter Lobner, Updated 21 December 2020 1. Introduction The UK firm Airship Industries manufactured conventional airships from 1980 to 1990 and was based in giant purpose-built hangars at Cardington, Bedford, which is a site historically associated with British airship production. Airship Industries went into receivership in 1990, with the new firm Airship Technologies emerging as the successor company, but not for long. Airship Technologies soon folded and was succeeded by the firm Advanced Technologies Group (ATG), which was led by Jeffery R (Roger) Munk. ATG became well known for two advanced airship projects: • A hybrid, heavy lift airship known as the Sky Catamaran, or “SkyCat” for short, started in about 1999. • A stratospheric High Altitude Platform (HAP) named “StratSat,” for delivering a range of communications and surveillance services from geo-stationary positions in the stratosphere, started in 2001. Both advanced projects led to the development and testing of sub- scale prototype airships and advanced designs for full-scale airships. ATG also offered a range of conventional, non-rigid blimps, but built only one AT-10 airship. World SkyCat Ltd. was created in July 1999 as the marketing and operating associate of ATG for the SkyCat range and was intended to be the launch customer for the first SkyCat hybrid airship. In spite of promising business prospects for the SkyCat on the US military HULA and WALRUS heavy cargo airship programs, ATG and World SkyCat failed to generate the financial commitments needed for SkyCat production. ATG also failed to capitalize on their first StratSat business opportunity in Malaysia. -
SOME HISTORICAL HIGHLIGHTS Introduction
DOI: 10.2478/cdem-2020-0001 CHEM DIDACT ECOL METROL. 2020;25(1-2):5-34 Zbigniew A. SZYDŁO 1 HYDROGEN - SOME HISTORICAL HIGHLIGHTS Abstract: The early history of experiments in which an inflammable air was prepared is outlined. Once hydrogen had been discovered by Cavendish in 1766, the world of science and technology was given a colossal impetus. Its scientific and social consequences form the main focus of this essay. Special attention is given to explain why experiments were done, and their aims. The many difficulties which confronted scientists in the interpretation of their results are discussed. Timelines have been used in order to facilitate an understanding of the evolution of ideas. A particular emphasis is given to the story of how, through spectral analysis of the hydrogen atom, our understanding of atomic structure developed. Experiments involving hydrogen constitute important teaching material in schools. Detailed instructions are given for making hydrogen in the laboratory and for demonstrating its lightness and flammability. Suggestions are made of how to use these reactions to teach a wide variety of chemical concepts and facts. Keywords: hydrogen, gas, chemistry, atom, experiment Introduction There can be few better ways to introduce the subject of hydrogen to an audience, than to prepare it from a chemical reaction, fill a balloon with it and demonstrate its lightness, flammability and explosive combustion with oxygen. These effects can be achieved in simple demonstration experiments. To prepare hydrogen and to fill a balloon with it, use high quality latex balloons of 30 cm (12”) diameter. Apparatus and reagents: 500 cm 3 plastic fizzy drink bottle, 150 cm 3 20 % (approx.
