A guy gets set up on a blind date and he takes her out for dinner to a very expensive restaurant to make a good impression. The waiter approaches the table and asks to take their order.
The lady begins ordering practically everything on the menu, shrimp cocktail, pate, Caesar Salad, lobster, crepes Suzette, with no regard to the price. The guy is getting very upset, as he never thought she would order so much.
She then stops, and looks across at him, and asks, "What do you suggest I wash it down with?"
"Well my dear, how about the Mississippi river?"

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.
