    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.

  • 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...."

Do you know on how to start employment background check for your employees? Employment background checks would be your shield to prevent you from employment fraud.

Doing an Employment Background Check is one effective tool to ensure that the company has made the right employment choice. It covers beyond the applicant's qualifications; it puts everything and everyone in the company safe physically and financially.

There are two major elements in performing employment background screening. These are the criminal record check and the credit record check. Included in the criminal background screening are information such as arrests, lawsuits and other problems related to the court system.

Whatever information the company may get during the criminal background check can be a decisive factor on his employment. For example, a record that the applicant mauled or attacked fellow employees seriously that a case was filed against him can cause hesitation on his employment.

On the other hand, credit record screening is especially helpful when the position to be filled in requires handling financial matters. However, this is not the only use of doing consumer report, the technical term for credit record. In all aspects of employment, having a clean credit record is attractive.

In most cases, criminal background check is free. On the web are sites that offer free criminal background check, which includes criminal court records, civil court records and sex offender information. Also included on employment background screening specifically in criminal check are records on felonies and misdemeanors.

To accomplish criminal background checking, simply fill in the information requested on the provided boxes on the web page of the free service provider. This information includes the potential employee?s first and last names and the State to which he lives.

To be more specific, there is an option of providing the birth date. In fact, this is helpful in narrowing down the results of background searches. Once the information is given, click on search and the web will produce results in a matter of seconds.

At most, a background search on credit record does not come free. It needs to be purchased from a credit union and sometimes, requires the approval of the employment candidate. The information obtained during this stage of employment background check forms the major part of the applicant?s credit history.

Employment background screening particularly the consumer report can also be done online. However, some information is limited to criminal activity in relation to credit matters. The steps are similar in doing free online criminal background check, except that this time, it requires legal notification, which is available at the bottom of the application.

From an employees? perspective, employment background check guarantees safe working environment for people. For employers, background searches save them from any potential harm done to their properties, finances and work force.

Companies that offer services such as providing nannies can also perform nanny background check and at rare times, even require drug test as part of the employment background check. Other background investigations may involve inquiry from previous employers, relatives, neighbors and friends.

Anybody from the Human Resource department can do the employment background screening. Two steps serve as a good guide. The first is to gather the basic information such as the complete name, birthday information, telephone number and the address. The social security number, information on previous employment are good sources of information for background searches.

The second step is to confirm the applicant's identity. Using the information gathered, contact the number or the address to verify the person. If this is not possible, Google is reliable source to confirm the information. If the steps are not possible, public records search can do the employment background check.
