    ALKALINE DRY-CELL PATENT
    November 15, 1960 - U.S.A.

    A U.S. patent was issued for an alkaline dry-cell to P.A. Marsal, Karl Kordesch and Lewis F. Urry who assigned it to the Union Carbide Corporation, the manufacturer of Eveready batteries (No. 2,960,558). Compared to the existing carbon-zinc dry-cells, it offered an appreciable increase in life-span and efficiency during heavy continuous drains. Its construction used an alkaline electrolyte, manganese dioxide as depolarizer, a zinc powder-gel anode, and certain additives such including mercury and electrolyte-creep inhibitors. The patent gave practical details for commercial production. The patent claimed that whereas four cells in series of the carbon-zinc type gave 4.5 volts to power a 1.25-amp bulb for 45-min to 1-hr, the new alkaline design gave good brilliance after 6 to 7 hours.

    DRY-CELL PATENT
    November 15, 1887 - U.S.A.

    German scientist, Dr. Carl Gassner, was issued a U.S. patent (No. 373,064), the first in the U.S. for a "dry" cell. Gassner had already patented his invention in Germany (No. 37,758) on 8 Apr 1886, and also in Austria, Belgium, England, France and Hungary in the same year. The sealed zinc shell which contained all the chemicals was also the negative electrode. Later, he improved the shelf life of the battery by adding zinc chloride to the electrolyte to reduce corrosion of the zinc shell. Gassner's battery was much like the carbon-zinc, general-purpose batteries sold today. By 1896, the National Carbide Company (later Union Carbide and Eveready) produced the first consumer dry cell battery. Two years later, the company made the first D cell.

    about Eyesight Myth and Fact

    Myth: Staring at a computer screen all day is harmful to the eyes. Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.

The rumors carried way more hype about the Yahoo MSN merger than the actual deal. Since a long time it was always too close to the final step, but now when it is finally happening, all the baubles of gossip just vanished!!! Pooof! Yahoo now finally must take significant steps to improve on it?s content to stay in the league. Also it can use some help to look good on Google as probably it is where now Yahoo would be searched more!

We were always wishing that somehow, through some sort of miracle, Yahoo could pull it through. Yahoo has done great until recently. It has been pretty good with information and has always got something good for the people using it for search purposes. But since last year when they started making drastic changes in their algorithms, it has seriously gone down from the favorites list of many. But with the two- i.e. Yahoo and MSN combining, they seriously need to look into the MSN/Bing algorithm. They might be able to earn bucks from their display media, but they cannot count for long on searchers if they do not do anything about the algorithm problem. They would only lose significant searchers to the already more popular Google.

There is a strong possibility that with the merger there might finally be someone who could challenge the monopoly of Google. But there are also views on the contrary. With Google grabbing the market share, Yahoo was pushed away to the number two and MSN was lingering somewhere on a number three. The merger now limits the number of major search engines to two. This might be good for some and not so good for others. For a consumer it might not be such a great news as now they are restricted to only two search engines. Where earlier one had a possibility to find relevant search results at three places, now they would have only two. Nonetheless a great news for capitalists! On the brighter side, the number three slot is now vacant for a potential competitor. Seeing that one fill could be a stimulating experience.
