Visiting a clinic one day, Joe...

Visiting a clinic one day, Joe looked into the nurses eyes and said, "Nurses aren't supposed to laugh, right?"
"Of course I won't laugh. I'm a professional nurse. In over twenty years I've never laughed at a patient."
"Okay then," Joe said, and proceeded to drop his trousers, revealing the tiniest man penis the nurse had ever seen. Length and width, it couldn't have been bigger than a AAA battery.
Unable to control herself, the nurse started giggling then almost fell to the floor laughing.
A few minutes later she was able to regain her composure.
"I'm so sorry," said the nurse. "I don't know what came over me.
On my honor as a nurse and a lady, I promise it won't happen again. Now tell me, what seems to be the problem?"
"It's swollen," Joe replied.

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 In 1937 the invention of catalytic cracking superceded the Burton process, but it remains in wide use.«
