Belated Guardian Angel

Walking down the street, a man hears a voice: Stop! If you take one more step, a brick will fall down and kill you.
The man stopped; a big brick fell in front of him. The astonished man continued walking to the cross walk.
The voice shouted, Stop! If you take one more step, a car will run over you and you will die.
The man stood still; a car came careening around the corner, barely missing him.
Where are you? the man asked. Who are you?
I am your guardian angel, the voice answered.
Oh yeah? the man asked. Where the hell were you when I got married last week?

Edison patent

In 1922, Thomas A. Edison was issued a U.S. patent for a "Storage-Battery Electrode and the Production of Same" (No. 1402751). The electrodes were intended for batteries of the Edison type using nickel hydroxide for the active material for the positive elements and electrolytically active iron as the active material for the negative elements in an alkaline solution. The improved electrode element was designed to provide a high discharge rate by decreasing the internal resistance of the cell. The electrode element consisted of a thin metallic plate with small and closely adjacent perforations. The metal surface had a thin coating or film of a hydroxideof a suitable metal (preferable nickel) applied by electrolytic deposition.«[Image: one of the patent diagrams showing a fragmental sectional view of the electrode element.]
