    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.

    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.

  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."
  • Until a man duplicates a blade of grass
    by Earth Day, Thomas Alva Edison Inventor

    "...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

Many people most of the time travel. It's not a great think but when you are traveling with your pet that time you need to concentrate more on your pet which may disturb you to enjoy your vacation.

If your pet is very young or old, or is ill, pregnant, injured recovering form surgery then avoid to take them with you as is such time they need more concentration and if you really wish to carry your pet in your vacation then consult with pet sitter rather than take a chance on injuring your pet by taking it with you. If you are in doubt, ask your veterinarian. If your pet has not traveled before, try a short overnight or weekend trip first.

Before you leave inform your veterinarian where you will be traveling to, for how long, as well as whether your pet will be traveling by air or car. Ask about any flea, heartworm, or tick risks for areas you will be traveling to. If your pet becomes carsick or restless when traveling, ask veterinarian about appropriate medications or treatments.

Many times while traveling it happen we get separated from our pet and they get panic so try to avoid such type of situation for traveling safely with your pet. Your pet should wear a safety collar all the time with a tag showing proof of rabies vaccination and your name address, phone number in case your pet becomes separated from you.

To take care of your pet when away from home try to keep fresh water available and don think of changing their die all of a sudden. Make sure your pet is accustomed to the crate before you begin your trip.
