The Gift

On the first day of school, the children brought gifts for their teacher. The florist's son brought the teacher a bouquet of flowers. The candy-store owner's daughter gave the teacher a pretty box of candy. Then the liquor-store owner's son brought up a big, heavy box. The teacher lifted it up and noticed that it was leaking a little bit. She touched a drop of the liquid with her finger and tasted it.
"Is it wine?" she guessed.
"No," the boy replied. She tasted another drop and asked, " Champagne ?
"No," said the little boy... "It's a puppy!"

Edison patent

In 1882, Thomas A. Edison was issued a patent for an improvement to the telephone (No. 252,442). It described a carbon microphone. Finely divided conducting material, such as carbon, between metal cups mounted on arms is attached to the mouthpiece diaphragm. As sound waves directed through the mouthpiece move the diaphragm, the arms change the pressure on the carbon button which in turn varies an electric current passing through the carbon button. Changes in the current correspond to the pitch and amplitude of the sound. One arm conducts the electrical current to the carbon button, and the the other from it.
