Home in no time

A woman was waiting in the checkout line at a shopping center. Her arms were heavily laden with a mop and broom and other cleaning supplies. By her actions and deep sighs, it was obvious she was in a hurry and not happy about the slowness of the line.

When the cashier called for a price check on a box of soap, the woman remarked indignantly, "Well, I'll be lucky to get out of here and home before Christmas!"

"Don't worry, ma'am," replied the clerk. "With that wind kicking up out there and that brand new broom you have here, you'll be home in no time."

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.
