A young man was visiting his brother and sister-in-law for the holidays. As he arrived at their house he found his young nephew, Timmy, helping them bake some cupcakes.

After they were done, his sister-in-law allowed Timmy to put the icing on. When the boy had finished, he brought them to the table.

"The cupcakes look delicious, Tim." his uncle said. He took a bite and said, "Timmy these are so good."

As he finished cupcake and took another, he again complimented his little nephew. "The cupcakes look beautiful, Tim," his uncle said. "How did you get the icing so neat?"

His nephew replied, "It was easy. I just licked them."

The uncle turned pale. He pointed to the plate of cupcakes. "You licked all of these?"

Timmie replied, "Well no. After a while my tongue got tired, and I got the dog to help."

Stirling patent

In 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).«
