Why do you want a divorce?

A judge was interviewing a woman regarding her pending divorce, and asked, "What are the grounds for your divorce?"

She replied, "About four acres and a nice little home in the middle of the property with a stream running by."

"No," he said, "I mean what is the foundation of this case?"

"It is made of concrete, brick and mortar," she responded.

"I mean," he continued, "What are your relations like?"

"I have an aunt and uncle living here in town, and so do my husband's parents."

He said, "Do you have a real grudge?"

"No," she replied, "We have a two-car carport and have never really needed one."

"Please," he tried again, "is there any infidelity in your marriage?"

"Yes, both my son and daughter have stereo sets. We don't necessarily like the music, but the answer to your questions is yes."

"Ma'am, does your husband ever beat you up?"

"Yes," she responded, "about twice a week he gets up earlier than I do."

Finally, in frustration, the judge asked, "Lady, why do you want a divorce?"

"Oh, I don't want a divorce," she replied. "I've never wanted a divorce. My husband does. He said he can't communicate with me!"

Production of ammonia

In 1910, a U.S. patent for the Production of Ammonia was issued to Fritz Haber and Robert Le Rossignol (No. 971,501). This process could produce ammonia on a large scale directly from its component gases, hydrogen and nitrogen, by passing a mixture of them over heated finely-divided osmium metal used as a catalyst. A typical pressure of 175 atmospheres and a temperature of 550ºC could easily give an 8% by volume yield of ammonia. Although nitrogen makes up 80% of the air, as a gas it is quite unreactive. Despite its ready availability, nitrogen gas had previously been difficult to combine in a chemical form. Once nitrogen has been chemically combined in the form of ammonia, many other nitrogen compounds can be made.«
