This married couple was sitting in a fine restaurant when the wife looks over at a nearby table and sees a man in a drunken stupor.
The husband asks "I notice you've been watching that man for some time now. Do you know him?"
"Yes" she replies. "He's my ex-husband and has been drinking like that since I left him seven years ago."
"That's remarkable" the husband replies. "I wouldn't think anybody could celebrate that long."
Henry Livingstone SulmanBorn 15 Jan 1861; died 31 Jan 1940 at age 79.British metallurgist, one of the originators of the froth flotation process for concentrating ores preliminary to the extraction of metal (with H.F.K. Picard, U.S. patent No. 835120, 6 Nov 1906). In this latter method, crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. These reagents, such as oil or fatty acids, are chosen for a preferential affinity for metalliferous matter over the waste material (gangue). When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface, whereas gangue settles to the bottom. The froth is skimmed off, and processed. Sulman had previously worked on several methods for the extraction of gold, including treatment with cyanogen bromide. |
