    POLYPROPYLENE
    November 12, 1999 - Bartlesville, Oklahoma, U.S.A.

    In Bartlesville, Oklahoma, a plaque was placed on the site of the laboratory where the polymer polypropylene was invented, designating it a National Historic Chemical Landmark by the American Chemical Society. The first commercially successful use of the new material was in the Hula Hoop®. In 1951, J. Paul Hogan and Robert L. Banks, research chemists working for Phillips Petroleum Company, discovered the polymer unexpectedly during experiments with catalysts while trying to convert the natural gas components ethylene and propylene into compounds useful for gasoline. Later, they also developed a new catalytic process for making high-density polyethylene. Phillips soon invested in new plastic manufacturing plants.

    PITOT TUBE
    November 12, 1732 - Academy of Sciences, Paris

    Henri Pitot read a paper to the Royal Academy of Sciences in Paris about an instrument he had invented to measure the flow velocity at different depths of water in the River Seine. It had a scale and two open vertical glass tubes on a wood frame. The lower end of one pointed down, the other bent at 90 facing the flow. The belief of the time was that flow velocity at a given depth was proportional to the mass above it, meaning increasing velocity at greater depth. Recording the difference in liquid levels in the two tubes, he showed the opposite was true. Henri Darcy improved the design, with the support of Henri Bazin. Today, the Pitot tube has an important application in aerodynamics for the measurement of the airspeed of aircraft.

ARTICLE CONTENT :

Each time you play casino games online, you could fall prey to scam artists. It does not matter whether you play American roulette, blackjack, slots, keno or any other gambling game, you should constantly be aware of the possible online scams and take all necessary preventive steps to avoid being scammed. You can have a lot of fun playing online, provided that you preclude scams from interfering with your game. By observing the following steps, you can ensure a much safer gambling experience on the Internet.

- Before you ever sign up for any gambling site, make certain you have installed the latest anti-spyware and virus protection on your personal computer. You are also suggested to choose the automatic updating and scanning feature.

- Seek reputable sites only. Steer clear of new sites or the ones you are not able to find information about. You can turn to online gamblers that you know personally or check up gambling or news websites or other sources. The best advice: if you cannot find any dependable information on an online casino site, steer clear of it.

- Do not loan money to other online gamblers that you do not know in person. There are scammers that will begin conversations with you and carry on interacting for long periods of time just to gain your confidence. You may even meet some scammers who will promise to pay you off more.

- Do not reveal personal data by email, or respond to emails sent by online gambling sites. Some online gambling scams use e-messages that are purportedly sent by reputable websites, but they are actually a scam. Any time you have to update or change your personal information, do it on the main website only.

- Do not download any software program that promises it can assist you in playing any online gambling games. Some will state that it is possible to see other gamblers' cards, or help you win. However, these types of applications are likely to be a scam.

- steer clear of sites that guarantee you will win. When it comes to gambling, it is impossible to guarantee a win, and you are likely to lose more often than win.

Stay alert! Once you find a reputable site, stick to it.
