An English teacher reminds her...

An English teacher reminds her students of the written test in her class tomorrow:
"Now, I don't want anyone to miss this important finals exam! I will not tolerate any excuse whatsoever for your absence--unless of course you had to go to the hospital because of a serious injury, or someone died in your immediate family."
Just after she spoke, a wise ass in the back of the class exclaims: "Well, what if I were to tell you that I didn't show up for the test because I experienced complete and utter sexual exhaustion?"
The students in the class try to suppress their snickers and muffled laughter.
The teacher looks sympathetically towards the young man, smiles slyly and states: "Well, then...you'll have to write with your other hand".

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.]
