Oops

A doctor is going round the ward with a nurse and they come to the first bed where the chap is laying half dead.
"Did you give this man two tablets every eight hours?" asks the doctor.
"Oh, no," replies the nurse, "I gave him eight tablets every two hours!"
At the next bed the next patient also appears half dead.
"Nurse, did you give this man one tablet every twelve hours?"
"Oops, I gave him twelve tablets every one hour," replies the nurse.
Unfortunately at the next bed the patient is well and truly deceased, not an ounce of life. "Nurse," asks the doctor, "did you prick his boil?"
"OH MY GOODNESS!" replies the nurse.

Edison patent

In 1893, a patent for a "Roller for Crushing Ore or Other Material" was issued to Thomas A. Edison (U.S. No. 498,385). Edison had in mind crushing iron ore. "It is usual in ore crushing machines employing rollers to mount them in pairs on suitable supporting frames and to provide means for driving each pair, and for feeding material to be crushed separately to each pair of rollers and to provide separate means for pressing the rollers of each pair together. In the machine to be described I employ three or more rollers supported side by side in a frame and moveable towards or away from each other, instead of using them in pairs, and a single weight and lever serves to press all of said rollers together."Image: drawing of the side elevation of the apparatus.
