    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.

You have found an excellent groom and bought that superb dress. You're anticipating a flawless wedding. You now desire the perfect wedding venue. Choose wisely when finding a wedding venue. It is, after all, where you will share lasting memories with friends and relatives.

Here are some wonderful ideas for that perfect wedding venue.

Trust your intuition. When you arrive at a certain venue you will automatically have a certain reaction towards it. Trusting your instinct is important. If you have a good feeling about the venue then that's a good start.You will know if a particular venue is right for you or not. You should not however leave out the logical choices in choosing a wedding venue. It will have to feel right because you and the man you love will exchange vows here.

Pace yourself. Don't go rushing into choosing the perfect wedding venue. Having a wedding is one of the most important events in your life so you will want to make a wise decision. Try to start looking for a venue about a year before the wedding date if possible. You will then have enough time to make good decisions and alter the venue if something happens.

Think about the size. The venue size is vitally important in your decision. Pick a venue that is too tiny and it will be awkward and annoying. The wedding will loose its intimacy if the venue is too large. The number of guests will dictate the the size. You will need a rough idea of how many guests you will plan on inviting before looking for your wedding venue. Try to be as accurate as possible. Don't just say I want to invite from 200 to 500 guests. Such a large difference in the number of guest would affect venue size.Remember to leave enough space for the dance area. The more guests you have, the bigger space you need to designate for the dance area.

Review the parking area. Many people who have attended weddings complain of limited parking space. Make sure your choice of wedding venue has generous space for all of your guests. Parking may be a minor consideration but it could be the key between a satisfied guest and a frustrated one.

Find out if there are any restrictions for the venue. There might be some type of noise restriction which would hinder your decision to hire a band and have a loud sound system. There are time restrictions on some venues while others let you have a great time all night long. There are even some with restrictions on decorations.

Ascertain whether the venue would allow you to bring your own florist, caterer, decorator, etc because some might have specific professionals and contractors they would like you to use.

Create a diagram of your wedding. Have a setup on paper or your mind before choosing a wedding venue. You have to know where each of the following will be located: reception area, dining area, and seating for guests, etc. Then review whether your venue fits the setup you have in mind.
