You’re in Charge of...

An Italian, an Irishman and a Chinese fellow are hired at a construction site. The manager points out a huge pile of sand and says to the Italian, "You're in charge of sweeping". To the Irishman, "You're in charge of shoveling" To the Chinese guy, "And you're in charge of supplies". "Now, I have to leave for a little while. I expect you guys to make a dent in that pile."

So the manager goes away for a couple of hours. And when he returns, the pile of sand is untouched. He says to the Italian, "Why didn't you sweep any of it?

The Italian guy replies, "I didn't have a broom. You said the Chinese guy was in charge of the supplies, but he disappeared and I couldn't find him" So then the manager turns to the Irishman and asks why he didn't shovel.

The Irishman replies, "I couldn't get myself a shovel. You left the Chinese guy in charge of supplies and I couldn't find him." The manager is really pissed now, and storms off toward the pile of Sand looking for the Chinese guy.

Just then, the Chinese guy springs out from behind the pile of sand and yells, "SUPPLIES!"

Dry-cell patent

In 1887, 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.«[Image: The six-inch, 1.5 volt Columbia Dry Cell marketed by NCC in 1896.]
