Stay out of the dorms...

On the first day of college, the Dean addressed the students, pointing out some of the rules.

"The female dormitory will be out-of-bounds for all male students, and the male dormitory to the female students. Anybody caught breaking this rule will be fined $25 the first time."

He continued, "Anybody caught breaking this rule the second time will be fined $50. Being caught a third time will incur a hefty fine of $100. Are there any questions?"

"How much for a season pass?"

Aerosol spray patent

In 1939, the first U.S. patent for dispensing liquids under pressure from a disposable container was issued to Julius Seth Kahn of New York City (No. 2,170,531). The patent was titled "Apparatus For Mixing a Liquid With a Gas," but was the predecessor of the aerosol spray can. In this case, the patent more particularly specified a use for whipping cream "by discharging the cream and gas mixture through a constricted orifice." The cream could be contained in a common soda-pop glass bottle. Gas could be introduced at controlled pressure. An inexpensive valve discharged the whipped cream. Its use was extended to applications such as dispensing paints, pharmaceuticals and insecticides.
