    BLACK AMERICAN INVENTION
    January 10, 1888 - U.S.A.

    A U.S. patent was issued for the railway signal to the Black American inventor, A.B. Blackburn (No. 376,362). The type of signal was that designed to be operated by the wheels of a train. A lever was depressed as a train wheel travelled over it, to remotely operate an alert through a mechanical linkage upon the passing of the train. It was designed for use upon a single track railway line for trains passing in one direction. To provide a signal for trains passing in the opposite direction, a similar apparatus would be applied on the opposite rail. This patent was an improvement in mechanical design of his earlier patent No. 309,517 on 23 Dec 1884, in which he also described how a gong was activated to provide the alert.

    RECORD “SINGLES”
    January 10, 1949 - 7-inch diameter 45 rpm, U.S.A.

    RCA introduced the “single,” the 7-inch diameter 45 RPM record in the U.S.A single could play eight minutes of sound per side. Columbia had introduced the 12" long-playing vinyl 33 RPM as a new format the previous year. These formats greatly improved upon the 78 RPM records, which were limited to only 5 minutes per side on a 12" disk. Vinyl records were less fragile, and had a lower level of surface noise, but needed new playing equipment. RCA subsequently manufactured a record-player with a wide-diameter spindle to automatically play a stack of singles. The 45 RPM, 7" record was favored by the young, and became successful with the onset of rock and roll. In the UK sales of 45s overtook 78s early in 1958.

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.
