  • The appliance of science: Humphry Davy's electrochemical protectors for ships' bottoms in the 1820s

    Publication Year: 1995 , Page(s): S11 - S16

    This paper investigates the problems surrounding the application of the scientific knowledge of electricity for practical purposes in early nineteenth century Britain. It concentrates on the attempt by the Admiralty and Navy board to seek a method of protecting from corrosion the copper sheeting on the bottoms of ships. The method of using electrochemical `protectors' (sacrificial cathodic protection) was proposed by Humphrey Davy as a solution to the problem. Though the science was faultless, the application, as the paper relates, led to disaster View full abstract»

  • Representations of transatlantic telegraphy

    The successful laying of a telegraph cable across the Atlantic in 1866 had a major impact on Victorian society. An important part of the process of habituating the public to the new technology was the representation of submarine telegraphy in books and magazines, such as Punch and the Illustrated London News, aimed at an educated, disinterested audience. This paper examines some typical representations in prose, poetry, and pictures View full abstract»

  • J.N. Aldington and electric lighting

    Much has been written about the development of the electric arc and the filament lamp, but very little about the history of discharge and fluorescent lighting. Their development may, however, be followed in the technical journals from the late 1920s on, and the name of J.N. Aldington often appears. He was actively involved in many aspects of lighting development, though his special interest was the high-pressure mercury arc. He wrote and lectured on lamps and lighting, and on the history of electric lighting. He became a Fellow of the IEE and President of the Illuminating Engineering Society. This paper gives an account of his life and the developments in which he was involved and is drawn mainly from papers which the Aldington family have recently given to the Institution Archives View full abstract»

  • Charles Townes, the maser, and the relationship between engineering and science

    Publication Year: 1995 , Page(s): S41 - S46
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (1448 KB)  

    Charles Townes is renowned as the inventor of the maser and for his work on molecular spectroscopy and astronomy. Engineering has been an important element of his career, which illustrates how fruitful a combination of scientific and engineering knowledge can be. The author describes the life and work of Townes and how he developed microwave spectroscopy and the maser, and his interest in astronomy View full abstract»

  • Prophecy into practice: the early rise of videotelephony

    Publication Year: 1995 , Page(s): S33 - S40

    In 1993 BT launched a new product-a videotelephone. Its arrival had been prophesied in the latter half of the nineteenth century and, indeed, in 1930 Bell Telephone Laboratories in the USA demonstrated a two-way television system in which the subject was scanned mechanically by a light spot. However, the most extended-in space and time-two-way public television service, pre-war, was that managed by the German Post Office whose Berlin-Leipzig service cost DM3.50 for a 3 minute connection. Such early services were very limited and the prospect of a widely distributed commercial service had to wait until bandwidth compression techniques and wide-band optical-fibre communication networks were available. The author discusses these early systems View full abstract»

  • Four pioneer deep-sea cables

    Publication Year: 1995 , Page(s): S26 - S32
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (988 KB)  

    Despite the existence of satellite systems the demand for transatlantic communication cables does not seem to have declined. This paper outlines the story of the two telegraph cables of 1858 and 1866, and of the two telephone cables of 1956 and 1961. In the early days the main challenge was in laying long cables in deep water. Amplifiers and carrier-frequency techniques had to be introduced for telephony. The lightweight cable of 1961 pioneered the use of deep-sea cable with strength members in the core rather than in surrounding armouring View full abstract»
