| From 1851, Chance Brothers also became a major lighthouse engineering company, producing optical components, machinery, and other equipment for lighthouses around the world. James Timmins Chance pioneered placing lighthouse lamps inside a cage surrounded by fresnel lenses so as to increase the available light output; these cages, known as optics, revolutionised lighthouse design. Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution that the light flashes. John Hopkinson, the noted English physicist and engineer, invented this system. locksmithLeather Beds | |

| Underground TankEzcloneOne of the paper's most controversial moments came in 1966, during the Ian Brady and Myra Hindley murder trial, when it emerged in court that the key prosecution witness had been paid by the paper to give his side of the story. David Smith accepted £1,000 and was sent on holiday to France as well. The attorney general was asked to investigate what the judge called "a gross interference in the course of justice" but the newspaper escaped contempt charges. | |
