James Bicheno Francis

Born 18 May 1815; died 18 Sep 1892 at age 77.British-American engineer who originated scientific methods to test hydraulic machinery and invented the Francis mixed-flow reaction turbine (combining radial- and axial-flow) for low-pressure installations. He emigrated to the U.S. at age 18, and joined the Locks and Canal Co., Lowell, Mass. In 1837, he became its Chief Engineer until retirement. The company owned and operated Lowell's canal system providing waterpower for the textile industry there. Francis designed a more efficient successor to the Boyden turbine, with Uriah A. Boyden of Boston. Being half the size but equal in power, two fit in each wheel pit and doubled power generation.The turbine acted as a hydraulic motor to drive many mill machines through belts and line shafts. He was a founding member of the American Society of Civil Engineers and its president in 1880.«

A man and an ostrich walk into...

A man and an ostrich walk into a restaurant. The waitress asks, "What will it be?"
The man replied "a burger and a coke." "And you?" "I'll have the same," the ostrich replies. They finish their meal and pay. "That will be $4.50," The man reached into his pocket and pulled out the exact amount. They do this every day till Fri.
"The usual?" she asked. "No, today is Friday. I'll have steak and a coke."
"Me too." says the ostrich. They finish and pay. "That will be $10.95"
The man reached in and pulls out the exact amount again just like all week.
The waitress was dumb-founded. "How is it that you always have the exact amount?"
"Well," says the man. "I was cleaning my attic and I found a dusty lamp. I rubbed it and a genie appeared." Wow!" said the waitress. "What did you wish for?"
"I asked that when I needed to pay for something, the exact amount would appear in my pocket." "Amazing! Most people would ask for a million dollars. But what's with the ostrich?" "Well," said the man. "I also asked for a chick with long legs."
