Once upon a time the governmen...

Once upon a time the government had a vast scrap yard in the middle of a desert. Congress said, "Someone may steal from it at night." So they created a night watchman position and hired a person for the job.
Then Congress said, "How does the watchman do his job without instruction?" So they created a planning department and hired two people, one person to write the instructions, and one person to do time studies.
Then Congress said, "How will we know the night watchman is doing the tasks correctly?" So they created a Quality Control department and hired two people. One to do the studies and one to write the reports.
Then Congress said, "How are these people going to get paid?" So they created the following positions, a time keeper, and a payroll officer,then hired two people.
Then Congress said, "Who will be accountable for all of these people?" So they created an administrative section and hired three people, an Administrative Officer, Assistant Administrative Officer, and a Legal Secretary.
Then Congress said, "We have had this operating for one year and we are $18,000 over budget. We must cutback overall cost."
So they laid off the night watchman.

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.]
