A man realized he needed to purchase a hearing aid, but didn't want to spend a lot of money. "How much do they cost?" he asked the salesman.
"Anything from $2 to $2,000."
"Can I see the $2 model?" said the customer.
The salesman put the device around the man's neck, and said: "You just stick this button in your ear and run this little string down into your pocket."
"How does it work?" asked the customer.
"For $2, it doesn't work," said the salesman. "But when people see it on you, they'll talk louder."

Patent for cotton spinning

In 1791, a U.S. patent for spinning cotton by water power was issued to William Pollard of Philadelphia. In his petition, Pollard had stressed usefulness and an important economic value to the U.S., rather than novelty. Actual details of any machine were vague and secondary his claims being of deserving character. Pollard was one of three British immigrants that sought exclusive rights to introduce into America cotton spinning machines based on those devised by Richard Arkwright in England. By Jun 1791, Pollard's factory was in full operation, and is said to be the first water frame built in that city. However, it was not successful, and for that reason may have in effect retarded the growth of the industry in Philadelphia.«
