A carabiner is a common piece of mountain climbing equipment, a metal clip that allows climbers to link together ropes and harnesses. If you're learning to rock climb, you'll most likely use a carabiner. Carabiners are vital for climbers and mountaineers to keep various pieces of equipment connected to each other, and thus to keep themselves safe while they're climbing. A carabiner can take various forms and shapes, but it's usually a metal oval, with a spring-loaded clip that stays closed unless it's pushed open.
In 1899, American Telephone & Telegraph (AT&T) acquired the assets of its parent, the American Bell Telephone Company. American Bell had created AT&T to provide long-distance calls between New York and Chicago and beyond. AT&T became the parent of American Bell Telephone Company, and thus the head of the Bell System, because regulatory and tax rules were leaner in New York than in Boston, where American Bell was headquartered.
Bell demonstrated the telephone to Queen Victoria on 14 January at Osborne House on the Isle of Wight with calls to London, Cowes and Southampton. These were the first long-distance calls in the UK. The Telephone Company Ltd (Bell's Patents) was formed to market Bell's patent telephones in Great Britain. The company was registered on 14 June with a capital of 100,000.
