Tornadoes Of 1970
This page documents the tornadoes and tornado outbreaks of 1970, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes. Events United States yearly total January 9 tornadoes were reported in the United States in January. January 1 (Australia) An intense tornado, which occurred near the town of Bulahdelah ( north-northeast of Newcastle), New South Wales on 1 January 1970, is thought to be the most destructive tornado ever documented in Australia. It is thought to have reached F4 or F5 intensity on the Fujita scale, however, no official rating has been made public. The tornado left a damage path long and 1–1.6 km (0.6–1 mi) wide through the Bulahdelah State Forest. It is estimated that the tornado destroyed over one million trees. A caravan was destroyed ...

Lumber Mill
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logging, logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The Portable sawmill, "portable" sawmill is of simple operation. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation. Before the invention of the sawmill, boards were made in various manual labour, manual ways, either wood splitting, rived (split) and plane (tool), planed, hewing, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...

Big Nickel
The Big Nickel is a nine-metre (30 ft) replica of a 1951 Canadian nickel, located at the grounds of the Dynamic Earth science museum in Greater Sudbury, Ontario, Canada, and is the world's largest depiction of a coin. The twelve-sided nickel is located on a small hill overlooking the intersection of Municipal Road 55 and Big Nickel Drive at the westernmost end of the Gatchell neighbourhood. The Big Nickel celebrated its 45th anniversary on July 22, 2009 with a "birthday party" on the grounds of Dynamic Earth (Ontario), including a display of coins from Science North's Inco Coin Collection. Origin The idea for the Big Nickel began in 1963 when Ted Szilva, at the time a 28-year-old City of Sudbury fireman, read in the '' Sudbury Star'' of a contest, sponsored by the Sudbury Canada Centennial Committee (Maurice Lacourciere, Chairman), asking Sudbury residents how the City should celebrate the upcoming Canadian Centennial.

Inco Superstack
The Inco Superstack in Sudbury, Ontario, with a height of , is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest freestanding structure of any type in Canada, behind the CN Tower but ahead of First Canadian Place. It is the 51st tallest freestanding structure in the world. The Superstack is located on top of the largest nickel smelting operation in the world at Vale's Copper Cliff processing facility in the city of Greater Sudbury. In 2018, Vale announced that the stack would be decommissioned and dismantled beginning in 2020. Two new, smaller stacks were constructed under the company's Clean Atmospheric Emissions Reduction Project. In July 2020, Vale announced that the Superstack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in the event of a malfunction in the new ...

Derailment
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard. A derailment of a train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident. History The first recorded train derailment in history is known as the Hightstown Rail Accident in New Jersey that occurred on November 8, 1833. The train was traveling between Hightstown and Spotswood New Jersey and derailed after an axle broke on one of the carriages as a result of a journal box catching fire. The derailment resulted in ...

Smelter
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including Silver mining#Ore processing, silver, iron-making, iron, copper extraction, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke (fuel), coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the Chemical energy, lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal Chemical element, element as a product. The carbon source is oxidized in two stage ...
