Q: Question: What materials are used as fuel in the type of furnace first used in the Weald to produce cast iron? Passage:Sir Francis Pettit Smith of Kent invented the screw propeller. Faversham Oyster Fishery is the oldest company in the world. Maidenhead Railway Bridge is known for its flat arch, built in 1839 with 39-metre spans. The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, and produced much of Britain's cast iron until the 1770s. Portsmouth Block Mills were the site of the world's first metal machine tools, built for the manufacture of wooden pulleys, invented by Henry Maudslay, and the site of the world's first industrial assembly line in 1803. South Foreland Lighthouse on 8 December 1858 was the world's first lighthouse with electric light, with the first type of industrial electrical generator made by Frederick Hale Holmes, from work he had carried out with Floris Nollet of Belgium, and 36 permanent magnets. By 1880, of the ten lighthouses with electric light, five were in the UK. From the lighthouse in 1899, the first international radio broadcast to France was made. Zénobe Gramme of Belgium made a much better design in 1870 with self-excitation of magnets, and the first modern dynamo. North Foreland Lighthouse was the UK's last-manned lighthouse until 1998.
