What's with the nuts?

A guy goes into a bar. He's sitting on the stool, enjoying his drink when he hears, "You look great!" He looks around - there's nobody near him. He hears the voice again, "No really, you look terrific."

The guy looks around again. Nobody. He hears, "Is that a new shirt or something? Because you are absolutely glowing!" He then realizes that the voice is coming from a dish of nuts on the bar.

"Hey," the guy calls to the bartender, "What's with the nuts?"

"Oh," the bartender answers, "They're complimentary."

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.]
