Time Off

Two factory workers were talking. "I know how to get some time off from work." said the man.
"How do you think you will do that?" said the other one. He proceeded to show her...by climbing up to the rafters, and hanging upside down.
The boss walked in, saw the worker hanging from the ceiling, and asked him what on earth he was doing? "I'm a light bulb" answered the guy.
"I think you need some time off," said the boss. So, the man jumped down and walked out of the factory. The second worker began walking out too. The boss asked her where did she think she was going?
"Home. I can't work in the dark."

Thomas L. Willson

Born 14 Mar 1860; died 20 Dec 1915 at age 55.Thomas Leopold Willson was a Canadian-American chemist and inventor who discovered a commercial production method for calcium carbide using an electric arc furnace. In 1893, he started a company with John Motley Morehead III in Spray, North Carolina, to try his ideas to obtain aluminium metal from its oxide. On 2 May 1892, he was using an electric arc furnace with coal tar and burnt chalk (lime). An unexpected dark, solid mass was formed. On cooling with water, a gas was given off. This burned with a bright yellow, smoky flame. Analysis showed these were calcium carbide and acetylene. Unlike the earlier method of Wöhler that made calcium carbide in an amorphous form, Willson had a hard, aggregated chrystalline form. He obtained (and defended) patents on his process. He assigned them to the Electro Gas Co. (which became Union Carbide Corp.) His other inventions included gas navigational buoys and electric arc lighting. He established calcium carbide manufacturing in Canada.«
