An old man goes to the Wizard to ask him if he can remove a curse he has been living with for the last 40 years.
The Wizard says: "Maybe, but you will have to tell me the exact words that were used to put the curse on you.
The old man says without hesitation: "I now pronounce you man and wife."
Fire sprinkler patentIn 1872, the first U.S. patent for an automatic sprinkler system was issued to Phillip W. Pratt, of Abington, Mass., titled “Improvement in Fire-Extinguishers” (No. 131,370). The system consisted of overhead, pivoted water-arms or perforated pipes, which when connected to a supply of water from a supply-pipe would revolve rapidly, throwing water in all directions, wetting ceiling, walls and floor. This operation was controlled by a valve opened by a spring-loaded lever, held closed by a system of cords and fuses. In case of a fire, when the fuses ignited, the cords burned, and the valve opened releasing the scattered stream of water. Pratt was an inventor holding a number of other patents, and is also credited with demonstrating the first electrically powered automobile in the U.S., a tricycle, on 27 Jul 1888. |
