One day, a man was dragged to the cinema by his wife who wanted to watch a romantic comedy.
Half an hour into the film, the man felt a nudge in his elbow. "What an outrage," his wife murmured to him.
"The person sitting in front of us is sleeping!" the woman said, clearly offended.
Her husband was fairly annoyed.
He replied: "You woke me up to tell me that?"
Coal pipeline in serviceIn 1957, the first U.S. commercial long-distance coal slurry pipeline, 108 miles long, began delivery from a coal mine (Georgetown Preparation Plant of the Hanna Coal Company, near Cadiz, Ohio) to a power station (Cleveland Illuminating Company, in Eastlake, Ohio). Completed on 12 Sep 1956, the 10-3/4 inch diameter pipeline could transport over a million tons of coal per year. Mixed with an equal amount of water, it delivered 150 tons of coal per hour. The coal slurry was then processed to remove the water, and made ready for burning. Slurry pipelines now exist transporting over twenty types of minerals, including iron-ore concentrate, copper ore, phosphate rock concentrate, limestone, clay and mineral sands. Pipelines can be built to the mouth of mines at lower cost than railroads.« |
