Dry-cell patent

In 1886, German scientist, Dr. Carl Gassner, was issued a German patent (No. 37,758) for the first "dry" cell, which used zinc as its primary ingredient. He encased the cell chemicals in a sealed zinc container. Gassner's battery was much like the carbon-zinc, general-purpose batteries on the market today. Gassner also patented his invention in Austria, Belgium, England, France and Hungary in the same year. A U.S. patent was issued to Gassner in 1887 (No. 373,064) on 15 Nov 1887. In America, by 1896, the Nation Carbide Company, later Union Carbide and Eveready, produced the first consumer dry cell battery. Two years later, the company made the first D cell. Combined with the invention of incandescent light bulbs, portable electric lights became common.«[Image: The six-inch, 1.5 volt Columbia Dry Cell marketed by NCC in 1896.]

A Horoscope For The Workplace

Astrology tells us about you and your future simply by your birthday. The Chinese Zodiac uses the year of your birth. Demographics tell us what you like, dislike, whom you vote for, what you buy, and what you watch on TV. Well, the Corporate Zodiac goes a step further: simply by your job title, people will have you all figured out…

MARKETING: You are ambitious yet stupid. You chose a marketing degree to avoid having to study in college, concentrating instead on drinking and socializing, which is pretty much what your job responsibilities are now. Least compatible with Sales.

SALES: Laziest of all signs, often referred to as “marketing without a degree,” you are also self-centered and paranoid. Unless someone calls you and begs you to take their money, you like to avoid contact with “customers” so you can ” concentrate on the big picture.” You seek admiration for your golf game throughout your life.

TECHNOLOGY: Unable to control anything in your personal life, you are instead content to completely control everything that happens at your workplace. Often even YOU don't understand what you are saying, but who the heck can tell?! It is written that the geeks shall inherit the Earth.

ENGINEERING: One of only two signs that actually studied in school, it is said that ninety percent of all personal ads are placed by engineers. You can be happy with yourself: your office is typically full of all the latest “ergodynamic” gadgets.

ACCOUNTING: The only other sign that studied in school, you are mostly immune from office politics. You are the most feared person in the organization; combined with your extreme organizational traits, the majority of rumors concerning you say that you are completely insane.

HUMAN RESOURCES: Ironically, given your access to confidential information, you tend to be the biggest gossip within the organization. Possibly the only other person that does less work than marketing, you are unable to return any calls today because you have to get a haircut, have lunch, and mail a letter!

MIDDLE MANAGEMENT/DEPARTMENT MANAGEMENT/”TEAM LEADS”: Catty, cut-throat, yet completely spineless, you are destined to remain at your current job for the rest of your life. Unable to make a single decision you tend to measure your worth by the number of meetings you can schedule for yourself. Best suited to marry other “Middle Managers,” as everyone in your social circle is a “Middle Manager.”

SENIOR MANAGEMENT: Catty, cut-throat, yet completely spineless, you are destined to remain at your current job for the rest of your life. Unable to make a single decision you tend to measure your worth by the number of meetings you can schedule for yourself. Best suited to marry other “Senior Managers,” as everyone in your social circle is a “Senior Manager.”

CUSTOMER SERVICE: Bright, cheery, positive, you are a fifty-cent cab ride from taking your own life. As a child very few of you asked your parents for a little cubicle for your room and a headset so you could pretend to play “Customer Service.” Continually passed over for promotions, your best bet is to date your boss.
