A knight went off to fight in...

A knight went off to fight in the Holy Crusades but before leaving he made his wife wear a chastity belt. After tightly securing it to her, he handed the key to his best friend with the instruction: "If I do not return within seven years, unlock my wife and set her free to lead a normal life."
The knight then rode off on the first leg of his journey to the Holy Land, but he had only traveled barely an hour when he was suddenly aware of the sound of pounding hooves behind him. He turned to see that it was his best friend.
"What is the problem?" asked the knight.
His best friend replied: "You gave me the wrong key."

Rotolactor

In 1930, the Rotolactor, invented by Henry W. Jeffries, was housed in the lactorium of the Walker Gordon Laboratory Company, Inc., at Plainsboro, N.J. This was a 50-stall revolving platform that enabled the milking of 1,680 cows in seven hours by rotating them into position with the milking machines. A Rotolactor was displayed at the 1939 New York World's Fair as part of the "Dairy World of Tomorrow," exhibit in the Borden building. The glass-enclosed revolving Rotolactor platform carried 150 pedigreed cows were washed, dried, and mechanically milked twice daily. A favorite attraction of the Food Zone, the Rotolactor epitomized how technology advanced the production of such a widely-used product as milk.
