A man runs to the doctor and says, "Doctor, you've got to help me. My wife thinks she's a chicken!"
The doctor asks, "How long has she had this condition?"
"Two years," says the man.
"Then why did it take you so long to come and see me?" asked the shrink.
The man shrugs his shoulders and replies, "We needed the eggs."
Stirling patentIn 1816, Robert Stirling, age 26, applied for a patent for his "Heat Economiser" at the Chancery in Edinburgh, Scotland (No. 4081/1816). The patent described principles of heat regeneration to reduce fuel consumption in glass and other furnaces, with elements of what is now called the Stirling Cycle engine. The regenerative principle was to save fuel by heating the air required for combustion with the waste heat of the funace. The hot air or caloric engine design in his 1816 patent "came to nothing." His regenerative furnace system was crude, but made practical by Siemens forty years later. By 1 Feb 1827, Stirling took out another patent for a caloric engine which worked successfully (No. 5456) and again on 1 Oct 1840 (No. 8652).« |
