How to Determine the Age of a Furnace

History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.

Titanic: 40 fascinating facts about the ship

Previous page Laceyville Originally known as Braintrim see above and Skinner’s Eddy see below , the area for a couple centuries was a camping grounds for Indians of the Tuscarora tribe. When the Laceyville toll bridge was completed across the Susquehanna in , the fare was five cents for pedestrians and 25 cents for horses. Lackawanna Means “the stream that forks,” and the fork in question is the confluence of the Lackawanna River with the northern branch of the Susquehanna.

Lackawanna County was once part of Luzerne County, and the breakoff did not come easy. The first rumblings of secession were heard in the s, some 20 years after Bradford and Susquehanna counties had broken off, due mainly to the impracticalities, not to mention the social regression, of having to travel to Wilkes-Borough to transact official business.

With construction of a Titanic replica well underway in China , we’ve unearthed a few interesting facts about the original. The largest passenger vessel is now Harmony of the Seas, at The ship burned around tonnes of coal a day — hand shovelled into its furnaces by a team of men. Almost tonnes of ash were ejected into the sea every 24 hours. Facilities on board included a gym, pool, Turkish bath, a kennel for first class dogs, and a squash court. It even had its own on board newspaper — the Atlantic Daily Bulletin.

Only 16 wooden lifeboats and four collapsible boats were carried, enough to accommodate 1, people. That’s only one-third of Titanic’s total capacity, but more than legally required.

Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago.

It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present. If I hope to accomplish anything, it will be to simply encourage critical thinking.

One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position.

Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute. Those defending creation today who don’t have the time to devote their life’s study to gaining expertise in all fields of inquiry must principally be prepared to think critically, logically, and challenge unsubstantiated assumptions made by these people.

They must also keep a level head in the face of some vicious attacks and diatribes that will be directed against them, as is advised in the scriptures 1 Peter 3: By way of definitions, I want to point out that when I speak of “evolution,” I am referring to the popular contemporary use of the word, which in a nutshell is the belief that all life forms are related by ancestry, and that the first life form occurred spontaneously, all due to completely natural processes. When I speak of “creation,” I am referring to the inherently obvious fact that the origin of all life forms can be attributed to a creator who purposefully created them with planning and intent, and the documented fact that this occurred over the course of a week’s time several thousand years ago.

Ferrous metallurgy

Process[ edit ] Smelting involves more than just melting the metal out of its ore. Most ores are a chemical compound of the metal and other elements, such as oxygen as an oxide , sulfur as a sulfide , or carbon and oxygen together as a carbonate. To extract the metal, workers must make these compounds undergo a chemical reaction. Smelting therefore consists of using suitable reducing substances that combine with those oxidizing elements to free the metal.

Huge fire ripped through Titanic before it struck iceberg, fresh evidence suggests

The doomed vessel, which measured more than ft long and ft tall, went down with the loss of more than lives on April 15, during her maiden voyage from Southampton to New York. The Titanic makes it’s way out to sea Credit: Twelve men battled to bring the resulting conflagration under control, but it was still raging days later – as temperatures of between and degrees Celsius. A poster advertising the RMS Titanic before its fateful first voyage The vast majority of these – some 2, men, women and children travelling third class – were crammed below decks, far from the mahogany-lined luxury enjoyed by Benjamin Guggenheim and Lady Astor above.

Unusually, the ship was even reversed into its berth in Southampton to prevent passengers from seeing the marked side, Mr Molony will claim in a documentary, Titanic: It totally changes the narrative.

Purchasing an older home with an existing furnace can be a worry; a furnace often needs replacing after 15 to 20 years, so knowing its age is helpful in determining if a new furnace should be in the budget. Newer units may have a manufacturer’s date listed somewhere on the furnace; older furnaces require a bit more digging by looking at the serial number, which tells the manufacturer various pieces of information, including the age. Finding the serial number, however, may also require a bit of sleuth work.

Look at the interior of the metal door for a label or tag listing the furnace’s serial number. This may also show an actual manufacturer’s date, depending on the company that made the furnace. Older furnaces sometimes had the serial number stamped onto the fan itself, giving the necessary information even when a manufacturing label is absent. The first two digits can be the week of the year that the unit was manufactured, with the third and fourth number indicating the year.

Long Pond Ironworks was founded in and operated continually until , making iron for a wide range of purposes. Today, the ruins of three furnaces and other unusual buildings remain in a beautiful setting within Long Pond Ironworks State Park near the New York border. The barrack is a survivor of the Colonial and Revolutionary War periods, being the last of five built in New Jersey during the French and Indian War in response to complaints about forced quartering of British troops in private homes.

S Sainte-Pierre and Miquelon: Capone Stronghold — The day Al Capone arrived in this tiny French outpost off the Newfoundland coast, sporting his trademark straw boater, a local gendarme was reportedly so nervous all he could do was stare. However, he limited his comments to the straw hat. This was during the s, which was a heady time on the islands of Sainte-Pierre and Miquelon, just twenty kilometres off the southern coast of Newfoundland. Sainte-Pierre and Miquelon remained French territory, ceded to France under the Treaty of Paris, and French law made it legal to import alcohol into the islands during Prohibition.

It became illegal only when it was placed on high-speed smuggling boats bound for the United States. To prevent the bottles from clanging against each other in the boats, which might both damage the product and alert authorities, bottles were wrapped in burlap covers sewn by local women. Capone alone smuggled the contents of up to three hundred thousand cases of contraband liquor into the United States each month, and the wooden liquor crates left on the tiny French islands stimulated a housing boom.

One cabin made completely of crates became known as Cutty Sark Villa. Decades later, a couple Sainte-Pierre houses still had shingles and walls made from the sides of old Cutty Sark crates. There were also stomach-turning photos from an August field-day near Wasaga Beach, north of Toronto, in which Choice members competed to run down a live chicken and then tear it to bits. The biker with the largest chicken chunk won. Some of the stories were darker, like how a Kitchener-area man was beaten to death in a brawl with the Choice; how an eighteen-year-old girlfriend of a gang member was found semiconscious and seminaked in a Markham ditch with severe internal injuries; or how a businessman was beaten to death in a Vancouver clubhouse.

North York Moors

Natural history[ edit ] A view of the North York Moors The North York Moors National Park encompasses three main types of landscape, whose differences are clearly visible, and the coastal belt. There are predominantly green areas of pasture land, the purple and brown heather moorland, and woodland. The three kinds of scenery are the result of differences in the underlying geology and each supports different wildlife communities.

Mainly late summer flowering Calluna vulgaris here. Sandstones erode slowly and form poor acid soils which are deficient in nutrients. They are less permeable to water, impeding drainage and encouraging the formation of bogs.

History[ edit ] Prior to the arrival of Europeans, the land Wayne County encompasses was originally part of the Iroquois Confederacy, which had existed from around August 31, In , after numerous acts of subdividing, Seneca County was formed by the splitting of Cayuga County, which, in turn, was reduced in size by combining portions of Seneca and the remainder of Cayuga County to form Tompkins County in This highway left the future Wayne County region somewhat isolated and settlers desiring to locate there came by way of streams and lakes lying to the north of the road.

It was only a few years after that the “new road” came west, passing through the county, opening up the fertile Ganargua lands to easier settlement. In May of that year a small colony made up of the Stansell and Featherly families located at the junction of Ganargwa and the Canandaigua Outlet, calling the place Lyons, from a “fancied likeness of that city’s location on the Rhone”. After Pulteney’s death in the land was known as the Pulteney Estate. In , Williamson, a Scotsman, came to the unsettled wilderness in upstate New York to develop the land by building roads, selecting sites for towns, dividing land into lots, and building gristmills, taverns, stores and houses.
