One Last Confession

While a man was dying, his wife was maintaining a candlelight vigil by his side. She held his fragile hand, tears running down her face.
Her praying woke him from his slumber. He looked up, and his pale lips began to move slightly.
"My darling," he whispered.
"Hush, my love," she said. "Rest, don't talk."
He was insistent. "I have something that I must confess," he said in a tired voice.
"There isn't anything to confess," replied his weeping wife. "Everything's ok. Go to sleep."
The man blurted out: "No, no, I must die in peace. I...I slept with your sister, your best friend, her best friend, and your mother!"
"I know," whispered his wife, "that's why I poisoned you."

Edison patent

In 1888, Thomas A. Edision, with co-inventor Ezra T. Gilliland were granted a patent for "Railway Signaling" (U.S. No. 384,830). The invention related to signalling systems for communicating between stations and moving trains by induction from the telegraph wires to the roofs of the cars. In such a system, transmitters were vibrators operated by keys to send signals upon the line, and receivers were telephone receivers connected to the ground. The patent was for an innovation to increase the quickness, rapidity and clearness of the vibrations. By making the transmitted vibrations as short and distinct as possible, they may be more clearly reproduced at the receiver.
