Fuse

Off

In electronics and electrical engineering, a fuse (from the French fusée, Italian. fuso, “spindle”) is a type of sacrificial overcurrent protection weight loss device. Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. Short circuit, overload or device failure is often the reason for excessive current.

A fuse interrupts excessive current (blows) so that further damage by overheating or fire is prevented. Wiring regulations often define a maximum fuse current rating for particular circuits. Overcurrent protection devices are essential in electrical systems to limit threats to human life and property damage. Fuses are selected to allow passage of normal current and of excessive current only for short periods.

In 1847, Breguet recommended use of reduced-section conductors to protect telegraph stations from lightning strikes; by melting, the smaller wires would protect apparatus and wiring inside the building. A variety of wire or foil fusible elements were in use to protect telegraph cables and lighting installations as early as 1864.

A fuse was patented by Thomas Edison in 1890 as part of his successful electric distribution system.

A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-conducting and non-combustible housing. The fuse is arranged in series to carry all the current passing through the protected circuit. The resistance of the element generates heat due to the current flow. The size and construction of the element is (empirically) determined so that the heat produced for a normal current does not cause the element to attain a high temperature. If too high a current flows, the element rises to a higher temperature and either directly melts, or else melts a soldered joint within the fuse, opening the circuit.

When the metal conductor parts, an electric arc forms between the un-melted ends of the element. The arc grows in length until the voltage required to sustain the arc is higher than the available voltage in the circuit, terminating current flow. In alternating current circuits the current naturally reverses direction on each cycle, greatly enhancing the speed of fuse interruption. In the case of a current-limiting fuse, the voltage required to sustain the arc builds up quickly enough to essentially stop the fault current before the first peak of the AC waveform. This effect significantly limits damage to downstream protected devices.

The fuse element is made of zinc, copper, silver, aluminum, or alloys to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess. The element must not be damaged by minor harmless surges of current, and must not oxidize or change its behavior after possibly years of service.

The fuse elements may be shaped to increase heating effect. In large fuses, current may be divided between multiple strips of metal. A dual-element fuse may contain a metal strip that melts instantly on a short-circuit, and also contain a low-melting solder joint that responds to long-term overload of low values compared to a short-circuit. Fuse elements may be supported by steel or nichrome wires, so that no strain is placed on the element, but a spring may be included to increase the speed of parting of the element fragments.

The fuse element may be surrounded by air, or by materials intended to speed the quenching of the arc. Silica sand or non-conducting liquids may be used.

Add Mulling Spices to your Mead for a Special Holiday Treat

Off

Hot apple cider is a drink that gives us a certain feel linked to cold winter nights and the festivities of the holiday seasons. You can enjoy this exact feeling in a grown-up version by using mead, which is wine made with honey, and some mulling spices. It is a fantastic and delicious hot drink that will add a little warmth to your holiday festivities and it is a little known treat that your friends and guests will rave about. Mulling is the centuries old tradition of infusing spices into warmed up beverages and the typical spices used are allspice, nutmeg, cloves, cinnamon, star anise, and various fruit peels like orange or apple. Being a centuries old drink there is no better beverage than mead is for mulling. You can buy mulling spices in grocery stores or online retailers and in variou sunless tan s quantities ranging from 8-ounce containers to individually wrapped tea bags. Or you can make your own mulling spices to fit your taste by mixing equal portions of any or all of the spices except for the nutmeg; limit it to about half the quantity of any other ingredient. If you use 1 teaspoon of each ingredient use about one half teaspoon of the nutmeg. And with mulling you should experiment by adding amounts of apple peel, orange peel or even lemon peel. Add anything you think will give that holiday taste. Mulling is very easy to do and you can follow any process that you would normally do for making tea. The process I follow is to wrap a couple of teaspoons in cheese cloth or spice bags and let it steep in a half bottle of mead while being heated on the stove. But I don?t bring it to a boil.

How Many Pages a resume or CV Should Have

Off

A number of recruitment professionals prefer a one-page CV that is compact, clear, concise, and relevant to the job because of the sheer volume of CVs they receive and the time it takes to sort them. However, this is not a rule of thumb, and you cannot sacrifice your CV’s readability to make it conform to any arbitrary “rules” about CV length. As Grant Cooper, president of Strategic Resumes notes in the resume Critique Writer software that he authored: “Brief resumes are simply no longer effective in today’s increasingly competitive job market,” he said. “The advice that ‘They only want to see one-page resumes,’ is perhaps the single most outdated and incorrect statement job-seekers hear today.”Surveys show that employers who prefer a one-page CV are in the minority, and the situational view is prevalent, as Mark Gillespie, Certifi african mango ed Senior Account Manager, Management Recruiters/Sales Consultants of Arlington Heights says:I have no problem with a 2 or sometimes even 3 page CV, if the candidate’s background and accomplishments warrant it. When they try to cram too much on a 1 page CV they end up reducing the font size and if they fax it you can’t read it most of the time. Also for more seasoned or highly talented people there is no way they can give you a good idea of what they have done in just one page, they always end up leaving too much out and if the CV has no substance then I just toss it.As writer Susan Britton Whitcomb discovered while researching her popular book, Resume Magic (JIST Works): “I conducted a survey of HR managers from some of the Top 100 Companies to Work for (from the book of the same name by Levering and Moskowitz),” Whitcomb relates.

An Interesting Survey

Off

An investigative company in Finland recently does an interesting survey. It is about the age of group who buy through the internet some daily goods such as watches, shoes, jewellery, T-shirts, trousers, books etc. the study focuses on the average age of the customers who consume these goods. It reveals some facts: the age of customers who buy shoes or watches are the youngest, followed by T-shirt, trousers and books. Age of people who buy glasses on the internet is listed at the end. There are several reasons attributing to this result. Shoes and watches are mostly worn by the young people who desire fashion greatly. They use shoes as a symbol of fashion and vigor which represent their image and taste. Watch, have been considered as a symbol of status since long time ago, still play a significant part in showing a peoples status. S scholarships for high school seniors o watches are favored by those successful businessmen or celebrities. And the trend that successful entrepreneurs are becoming younger. Apart from this reason, young people also like the watches with cute and fashionable design which also used as a kind of decoration. Then why the glasses are listed at the end of the list? People who buy glasses on the internet belong to the kind of people who are unwilling to go outside and carefully budget their living expense, usually are old people. Glasses need some practical try-on process. So many people will take reserved attitude on this shopping manner. However, as a matter of fact, online shopping is a way that should be encouraged. On the internet, the glasses are generally much cheaper. There are large margin of profit of glasses industry, so the room for price shrinkage is also large.

The rate of use of the fossil fuels all over the world has drastically increased during the last decade. This is an alarming fact because the use of fossil fuels mostly does irreplaceable harm to the atmosphere and the environment. The energy experts as well as the environmental groups all over the world have been putting immense pressure on their respective governments, to lessen the rate of the use of the fossil fuels so that the world environment will be preserved.It is with this aim that many environmental pacts have been signed by various countries across the world. The sole target for such pacts has been the companies and the industries that contribute to the pollution through their various industrial activities. As a result the concerned industries that cause harm to the atmosphere have been short listed and the respective government nanacast s have been asked to curb the levels of the pollutants that they release to the atmosphere. Every investor across the globe in keen and avid to read news on gas and oil and the best place Gas and Oil News to read such news is this website.Since the fossil fuels like the coal and the crude oil has also become major contributors to global warming scenario their use for the various activities have also very well come under the scanner. Hence presently most of the oil and natural gas drilling companies that have been associated with the drilling activities, have started to concentrate on the exploration and the harnessing of other types of energy sources mainly the natural energy. Since the natural energy is one thing that is freely available these companies are finding it more profitable to invest and get adequate returns from such investments.

What is a Fine Malt Whisky?

Off

I am not pretending to be an authority with 40 years knowledge of the whisky business but I do remember in my younger days enjoying from time to time a malt whisky. I also new by choice I?d ask for a malt, though never quite sure why.I?ll try and provide a simplistic view of what and why a malt whisky is a fine whisky and with Scotland having in the order of 140 distilleries producing one or more whiskies then I must confess I tend to think of a malt as fine Scotch whisky.Generally speaking people mean a single malt whisky when they refer to a malt whisky and this is because the malt whiskies are distilled in distilleries which usually only produce one whisky. It is possible to have more than one brand of whisky from a distillery and this can be attributable to a number of factors. For ex inflatable boats ample a distillery may have a single malt whisky which is a mere 10 years old and then another brand name which is matured for a full 20 years. Similarly the unique flavour of a fine whisky is as much about how the whisky is matured and stored and specifically the history of the casks that are used. The Benriach distillery, for example, produces several brands and they are a mix of age and the casks that have been used. Benriach specifically refer to whisky being matured in originally American oak casks and then finished either in casks having been used for storing sherry, port or dark rum. In all these cases the actual distillation process may have been the same but how the fine whisky is stored and for how long are the key factors to the product which is eventually consumed and enjoyed.
