Let There Be Light

I was sitting at a bar and asked the bartender where I could find a prostitute.
He told me to go to the back door, down the dark alley and give the woman there 20 bucks.
So I go outside and hand a 20 to the woman there and started getting busy. After a few minutes, a cop walks past and shines a flashlight on us and says 'What the hell are you doing?'
I said 'Having sex with my wife.' He said 'I'm sorry, I didn't realize that was your wife.'
and I said, 'Neither did I till you shined a light on her.'

Flotation process patent

In 1898, English brothers Alexander and Francis El applied for a British patent (No. 21,948) for their flotation process to separate valuable ore, such as copper, from the gangue (worthless rock) with which it is associated when mined. It was the first practical equipment to extract metals from low-content ore. Pulverized ore is mixed with water and brought into contact with thick oil. The oil entraps the metallic constituents, which are afterwards separated, and gangue passed away with the water. Today, flotation methods remain vital in the mining industry, processing millions of tons of ores each year.
