A man and his wife are dining at a table in a plush restaurant, and the husband keeps staring at a drunken lady swigging her drink as she sits alone at a nearby table.
The wife asks, "Do you know her?"
"Yes," sighs the husband, "she's my ex-girlfriend. I understand she took to drinking right after we split up seven years ago, and I hear she hasn't been sober since."
"My God!" says the wife. "Who would think a person could go on celebrating that long?"
Edison patentIn 1878, Thomas A. Edison was issued a patent for “Quadruplex-Telegraph Repeaters” (U.S. No. 209,241). This invention is an improved method for one quadruplex circuit to repeat into another quadruplex circuit. The patent describes the electromagnets, local circuits, switches and connections. The circuits work into and operate each other, so that the message are repeated automatically into one circuit by the receiving instrument of the other circuit, instead of the finger key being operated by hand. |
