A woman was sure that her husband was cheating on her, and having an affair with the maid. So she laid down a trap.
One evening she suddenly sent the maid home for the weekend and didn't tell the husband.
That night when they went to bed, the husband gave the old story: Excuse me my dear, my stomach aches, and went to the bathroom.
The wife promptly went into the maid's bed. She switched the lights off. When he came in silently, he wasted no time or words but quickly got on top of her...
When he finished and was still panting, the wife said: "You didn't expect to find me in this bed, did you?" And then she switched on the light...
"No madam," said the gardener.

Thermal cracking patent

In 1913, a U.S. patent for the thermal cracking of crude oil was issued to William Merriam Burton (No.1,049,667). A crude petroleum mixture of various hydrocarbons can be separated into several groups of constituents by physical means, commonly distillation. His thermal cracking process used high heat and high pressure to chemically break longer molecules of less volatile components into smaller molecules, more than doubling the yield of gasoline which was much needed to fuel the motor industry. In its first 15 years of use the process saved more than 1 billion barrels of crude oil. In 1937 the invention of catalytic cracking superceded the Burton process, but it remains in wide use.«
