Dry-cell patentIn 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 Depressed Blonde Guy Walks Into A Bar
A Blonde Guy walks into a bar very down on himself. As he walks up to the bar the bartender asks, “what’s the matter?”
The Blonde Guy replies, “well I’ve got these two horses (sniff, sniff), and well… I can’t tell them apart. I don’t know if I’m mixing up riding times or even feeding them the right foods.”
The bartender, feeling sorry for the guy, tries to think of something he can do.
“Why don’t you try shaving the tail of one of the horses?”
The man stops crying and says, “that sounds like a good idea, I think I’ll try it.”
A few months later he comes back to the bar in worse condition than he was before.
“What’s the matter now?” the bartender asks.
The Blonde Guy, in no condition to be in public, answers, “I shaved the tail of one of the horses (sob, sob), but it grew back and I can’t tell them apart again!”
The bartender, now just wanting him to shut up or leave says, “why don’t you try shaving the mane, maybe that will not grow back.”
He stops crying, has a few drinks, and leaves.
A few months later the guy is back in the bar.
The bartender has never seen anybody in this sorry of a state.
Without the bartender even asking the fellow breaks into his problems. “I.. I shaved the (sob) mane of one of the (sniff) horses, and… it… it… grew back!”
The bartender, now furious at the guy’s general stupidity, yells, “for crying out loud, just measure the stupid horses. Perhaps one is slightly taller than the other one!”
The guy cannot believe what the bartender has said and storms out of the bar.
The next day the Blonde Guy comes running back into the bar as if he had just won the lottery.
“It worked, it worked!” he exclaims.
“I measured the horses and the black one is two inches taller than the white one!”
