    THERMAL CRACKING PATENT
    January 7, 1913 - U.S. patent (No.1,049,667)

    A U.S. patent for the thermal cracking of crude oil was issued to William Merriam Burton (No.1,049,667). A crude petroleum mixture of various hydrocarbons can be separated into several groups of constituents by physical means, commonly distillation. His thermal cracking process used high heat and high pressure to chemically break longer molecules of less volatile components into smaller molecules, more than doubling the yield of gasoline which was much needed to fuel the motor industry. In its first 15 years of use the process saved more than 1 billion barrels of crude oil. In 1937 the invention of catalytic cracking superseded the Burton process, but it remains in wide use.

    FIRST TYPEWRITER PATENT
    January 7, 1714 - England, UK

    The world's first patent for a “Machine for Transcribing Letters” was granted in England by Queen Anne to Henry Mill (1683?-1771), a waterworks engineer with the New River Company. The patent (No. 395) described the invention as “an artificial machine or method for impressing or transcribing of letters, one after another, as in writing, whereby all writing whatsoever may be engrossed in paper or parchment so neat and exact as not to be distinguished from print; that the said machine... may be of great use in settlements and public records, the impression being deeper and more lasting than any other writing, and not to be erased or counterfeited without manifest discovery.” There is no remaining record that he actually built the machine.

    about Stolen On New Year's

    More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

Online Drugstores: Upside And Downside :

ARTICLE INFORMATION :

The article features online pharmacies as the most popular way of buying drugs in the USA and discusses the possible pitfalls that can arise out of obtaining drugs from some online pharmacies.

ARTICLE CONTENT :

Many people have already switched to online pharmacies and consider them a far more convenient way to purchase medicines. There are two primary reasons why people choose to purchase prescription medicines online. The first is financial. Because of the economic policy of the U.S. Health care, consumers frequently have to pay a much higher price for medications than customers overseas. The other reason is privacy. Some people prefer to purchase their prescription drugs from online pharmacies, even at a higher price, than to talk to a physician personally about medical conditions, such as depression, loss of hair, or erectile dysfunction.

Sales of antidepressant medicines, Viagra, Propecia, and diet pills, such as Phentermine or Xenical, are a flourishing business today. For years, consumers near Canada have driven across the border to buy medicines at an affordable price from Canadian pharmacies. These days, customers nationwide can buy from a Canadian pharmacy by mail. Canadian pharmacies typically require an identification document and a valid prescription. Unless issued by a doctor who is besides accredited to practice medicine in Canada, U.S. Prescription drugs will be reissued by a Canadian doctor.

As Internet pharmacies gain a larger share of the prescription medication market, consumers must be aware of the possible problems associated with purchasing an online prescription for a drug, or buying a medication online. These issues get even more significant when ordering from overseas pharmacies. It is usually possible to obtain savings by buying prescription medications online, even from a major U.S. Pharmacy, when you have a prescription issued to you personally.

It is commonly not cheaper to purchase medications through an online prescription service, which usually marks up the price substantially even when nominally offering a prescription for free. That mark-up may be compared to the cost of an in-person medical examination, and may considerably exceed that cost when you need a refill. Also, as mentioned above, price cannot always be the leading factor. If you don't know for certain whether you will be shipped the actual drug which was prescribed for you, think twice before ordering.
