VelcroIn 1978, Velcro, the hook-and-loop fastener patent expired, releasing the design to manufacture of imitations. It was developed by Swiss engineer Georges de Mestral, who noticed how thistle burrs clung to his clothing during a hike in the mountains. Using a microscope, he discovered their natural hook-like shape. From 1948, he worked with a local weaver from a textile plant to design a “locking tape.” The important discovery was accidental - that nylon, when sewn under ultraviolet light, formed industructable hooks. Velcro uses two tapes, one with stiff “hooks” like the burrs which clings to the second tape with soft “loops” like the fabric of his pants. The trademarked name Velcro comes from “vel” or velvet and “cro” from the French word crochet which means hook.«
An older, white haired man walked into a jewelry store one Friday evening with a beautiful young gal at his side.
He told the jeweler he was looking for a special ring for his girlfriend.The jeweler looked through his stock and brought out a $5,000 ring and showed it to him.
The old man said, "I don't think you understand, I want something very special."
At that statement, the jeweler went to his special stock and brought another ring over.
"Here's a stunning ring at only $40,000," the jeweler said.
The young lady's eyes sparkled and her whole body trembled with excitement.
The old man seeing this said, "We'll take it."
The jeweler asked how payment would be made and the old man stated by check. "I know you need to make sure the check is good, so I'll write it now and you can call the bank on Monday to verify the funds and I'll pick the ring up Monday afternoon," he said.
Monday morning, a very teed-off jeweler phoned the old man. "There's no money in that account."
"I know", said the old man, "but can you imagine the weekend I had?"
