A brilliant young boy was app...

A brilliant young boy was applying for a job with the railways. The interviewer asked him: "Do you know how to use the equipment?" "Yes", the boy replied. "Then what would you do if you realized that 2 trains, one from this station and one from the next were going to crash because they were on the same track?" The young applicant thought and replied "I'd press the button to change the points without hesitation." "What if the button was frozen and wouldn't work?" "I'd run outside and pull the lever to change the points manually" "And if the lever was broken?" "I'd get on the phone to the next station and tell them to change the points," he replied. "And if the phone was broken and needed an electrician to fix it?" The boy thought about that one. "I'd run into town and get my uncle" "Is your uncle an electrician?" "No, but he's never seen a train crash before!"

Edison patent

In 1923, Thomas A. Edison was issued a patent concerning "Stylus Mounting" (No. 1,456,687), a mount for phonograph stylii formed of a jewel such as diamond or sapphire in which the stylus is partially enclosed in a metal holder and projects from a reduced end portion thereof. The particular improvement is to provide for the stylus to be firmly and rigidly held to prevent it from loosening in use. A method of reinforcing the stylus mounting is applied at its weakest point, which is where the stylus emerges. An electroplating cell is used to apply a nickel reinforcing collar to the stylus.
