Off to Vegas

A man came home from work one day to find his wife sitting on the front porch with her bags packed. He asked her where she was going and she replied "I'm going to Las Vegas."
He questioned her as to why she was going and she told him "I just found out that I can make $400.00 a night doing what I give you for free". He pondered that then went into the house and packed his bags and returned to the porch and with his wife. She said "And just where do you think you're going?"
"I'm going too!" he replied.
"Why?" She asked.
"I want to see how you are going to live on $800.00 a year"!

Samuel Hall

Died 21 Nov 1863 (born 1781).English engineer who invented the surface condenser for steam boilers (patented 1834), an important milestone of its era, because it possible to recirculate fresh water instead of using corrosive salt water in the boilers of ocean-going steam ships. Steam passed through a number of small condensing tubes cooled on the outside surfaces by the circulation of cold sea water around them. By keeping the boilers free of salt, a considerable saving of fuel was realized, and repair expenses were reduced. Initial trials were unsuccessful until improved by a patent by Spencer who inserted an indiarubber ring around each end of the tube to keep them properly water tight. Hall held more than 20 patents, mostly relating to steam engines and boilers.
