An engineer was crossing a road one day when a frog called out to him and said, "If you kiss me, I'll turn into a beautiful princess."He bent over, picked up the frog and put it in his pocket.
The frog spoke up again and said, "If you kiss me and turn me back into a beautiful princess, I will stay with you for one week."
The engineer took the frog out of his pocket, smiled at it and returned it to the pocket.
The frog then cried out, "If you kiss me and turn me back into a princess, I'll stay with you and do ANYTHING you want."
Again the engineer took the frog out, smiled at it and put it back into his pocket.
Finally, the frog asked, "What is the matter? I've told you I'm a beautiful princess, that I'll stay with you for a week and do anything you want. Why won't you kiss me?"
The engineer said, "Look I'm an engineer.
I don't have time for a girlfriend, but a talking frog, now that's cool."

Compound steam engine patent

In 1781, a British patent was taken out for the first compound steam engine by Jonathan Carter Hornblower (No. 1298). His invention was to use two cylinders of unequal size attached to the same beam. Steam acts first in a small high-pressure cylinder, leaving at a lower pressure, but still sufficient to expand further in a larger cylinder. Although he claimed greater efficiency, this was not realised at the low steam pressures of the day. Boulton and Watt claimed infringement on their earlier patent since this engine still used a separate condenser, so Hornblower had to abandon that design at the time. His compound steam engine principle was later revived in 1804 by Arthur Woolf using higher steam pressure with better results.«
