Chalk One Up For The Grandparents!

An elderly man in Miami calls his son in New York and says, "I hate to ruin your day, but I have to tell you that your mother and I are divorcing.

Forty-five years of misery is enough."

"Pop, what are you talking about?" the son screams.

"We can't stand the sight of each other any longer," the old man says.

"We're sick of each other, and I'm sick of talking about this, so you call your sister in Chicago and tell her," and he hangs up.

Frantic, the son calls his sister, who explodes on the phone, "Like heck they're getting divorced," she shouts, "I'll take care of this."

She calls her father immediately and screams at the old man, "You are NOT getting divorced! Don't do a single thing until I get there. I'm calling my brother back, and we'll both be there tomorrow. Until then, don't do a thing, DO YOU HEAR ME?" and hangs up.

The old man hangs up his phone and turns to his wife. "Okay," he says, "They're coming for Passover and paying their own airfares."

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.
