Electric motor

In 1904, the first direct current, interpole, electric motor to be patented in the U.S. was issued to Mathias Pfatischer of Phildadelphia, Pennsylvania under the title "Variable Speed Motor" (No.775,310). His improvement was to "effect commutation without sparking, with a variable load as well as at variable speed and which is capable of rotation in either direction." The new design added auxiliary-field pole-pieces which were small as compared to the main pole-pieces.«

Attending a wedding for the first time, a little girl whispered to her mother, "Why is the bride dressed in white?"
"Because white is the color of happiness, and today is the happiest day of her life."
The child thought about this for a moment, then said, "So why is the groom wearing black?"
