Immaculate Miracle?
A woman takes her 16-year-old daughter to the doctor. "Okay, Mrs. Jones, what's the problem?"The mother says, "It's my daughter, Debbie. She keeps getting these cravings, she's putting on weight, and she is sick most mornings." The doctor gives Debbie a good examination, then turns to the mother and says, "Well, I don't know how to tell you this, but your Debbie is pregnant--about four months would be my guess."The mother says, "Pregnant?! She can't be, she has never been left alone with a man! Have you, Debbie?" Debbie says, "No mother! I've never even kissed a man!" The doctor walked over to the window and stared outside. About five minutes passed before the mother said, "Is there something wrong out there, doctor?" The doctor replied, "No, not at it. It's just that the last time anything like this happened, a star appeared in the east and three wise men came over the hill. I'm not going to miss it this time around!"

Computer pumpIn 1932, the first U.S. patent for a computer pump was issued to the inventors, Robert J. Jauch, Ivan R. Farnham and Ross H. Arnold for their "Liquid Dispensing Apparatus" (No. 1,888,533). Their motorized pump both metered and displayed the exact gallons of gasoline or other liquid dispensed, and also accurately computed and showed the price in dollars and cents while delivery was made. The internal totalizer could be easily reset for any new price per gallon. It solved the problems of inaccurate delivery of volume from a visible type dispenser, and its necessary ready-reckoning card with quantity and cost tables, which needed a new card when prices changed. The Wayne Co., Fort Wayne, Indiana, marketed it from 1 Nov 1931.« |
