Casein fibre

In 1938, the first U.S. patent was issued for casein fibre (No. 2,140,274). Earl Ovando Whittier and Stephen Philip Gould of Washington, D.C. had first produced casein fibre in December 1935. They dedicated the patent "to the free use of the people of the United States of America." Casein is the main protein found in milk. Their invention was to produce dispersions of casein (mixed usually with plasticizers and salts), to be extruded into fibres having the requisite characteristics of strength, water resistance, flexibility, and softness necessary to make them suitable as substitutes for wool and other fibres. Some of the best plasticizers suggested were the fat acids to give the fibres flexibility, softness and water repellancy. Sodium aluminate improved the fibre's strength.

Harry was finally a groom and was very excited about his upcoming marriage.
He was on his way out of the office when his boss came over to him with an outstretched hand, "Congratulations Harry! I just wanted to tell you I've been married for twenty two years, and I am sure that you will always remember this day with the fondest of memories, as the happiest day of your life."
"But sir", said Harry, a little bit confused, "I'm not getting married until tomorrow!"
"Yeah, I know," said his boss.
