Door To Door

Two salesmen were going door to door, and knocked on the door of a woman who was not happy to see them. She told them in no uncertain terms that she did not want to hear their offer and slammed the door in their faces. To her surprise, however, the door did not close and, in fact, bounced back open. She tried again, really put her back into it, and slammed the door again with the same result-the door bounced back open.
Convinced these rude young people were sticking their foot in the door,she reared back to give it a slam that would teach them a lesson, when one of them said:

“Ma'am, before you do that again you need to move your cat.”

First U.S. Patent

In 1790, the first U.S. patent was granted to Samuel Hopkins of Vermont for a process for making potash and pearl ashes. Potash was important as an ingredient in soap and fertilizer. The patent was granted for a term of 14 years and signed by President George Washington, who had the previous month signed the first U.S. patent statute into law on 10 April 1790. Hopkins did not get Patent with a serial No.1 as thousands of patents were issued before the Patent Office began to number them. Congress had passed the Patent Act on 10 Apr 1790. Two other patents were granted that year - one for a new candle-making process and the other the flour-milling machinery of Oliver Evans. The next year, 1791, Samuel Hopkins also was granted the first Canadian patent.«
