  • 125 single minute exchange of dies

    Ops
    a technique for reducing the setup times of equipment. Single minute exchange of dies was developed by Shigeo Shingo to improve setup times in the Toyota production system. It is a simple technique that divides the elements of a setup task into internal activities (those that can only be performed when the machine is stopped) and external activities (those that can be performed in advance). Single minute refers to making the changes in less than ten minutes, while exchange of dies comes from the steel presses that were the focus of Shingo’s attention. By converting as many internal activities to external activities as possible, Shingo was able to reduce a four-hour setup time on a large press to less than ten minutes.

  • 126 Barnack, Oskar

    [br]
    b. 1879 Berlin, Germany
    d. January 1936 Wetzlar, Germany
    [br]
    German camera designer who conceived the first Leica camera and many subsequent models.
    [br]
    Oskar Barnack was an optical engineer, introspective and in poor health, when in 1910 he was invited through the good offices of his friend the mechanical engineer Emil Mechau, who worked for Ernst Leitz, to join the company at Wetzlar to work on research into microscope design. He was engaged after a week's trial, and on 2 January 1911 he was put in charge of microscope research. He was an enthusiastic photographer, but excursions with his large and heavy plate camera equipment taxed his strength. In 1912, Mechau was working on a revolutionary film projector design and needed film to test it. Barnack suggested that it was not necessary to buy an expensive commercial machine— why not make one? Leitz agreed, and Barnack constructed a 35 mm movie camera, which he used to cover events in and around Wetzlar.
    The exposure problems he encountered with the variable sensitivity of the cine film led him to consider the design of a still camera in which short lengths of film could be tested before shooting—a kind of exposure-meter camera. Dissatisfied with the poor picture quality of his first model, which took the standard cine frame of 18×24 mm, he built a new model in which the frame size was doubled to 36×24 mm. It used a simple focal-plane shutter adjustable to 1/500 of a second, and a Zeiss Milar lens of 42 mm focal length. This is what is now known as the UR-Leica. Using his new camera, 1/250 of the weight of his plate equipment, Barnack made many photographs around Wetzlar, giving postcard-sized prints of good quality.
    Ernst Leitz Junior was lent the camera for his trip in June 1914 to America, where he was urged to put it into production. Visiting George Eastman in Rochester, Leitz passed on Barnack's requests for film of finer grain and better quality. The First World War put an end to the chances of developing the design at that time. As Germany emerged from the postwar chaos, Leitz Junior, then in charge of the firm, took Barnack off microscope work to design prototypes for a commercial model. Leitz's Chief Optician, Max Berek, designed a new lens, the f3.5 Elmax, for the new camera. They settled on the name Leica, and the first production models went on show at the Leipzig Spring Fair in 1925. By the end of the year, 1,000 cameras had been shipped, despite costing about two months' good wages.
    The Leica camera established 35 mm still photography as a practical proposition, and film manufacturers began to create the special fine-grain films that Barnack had longed for. He continued to improve the design, and a succession of new Leica models appeared with new features, such as interchangeable lenses, coupled range-finders, 250 exposures. By the time of his sudden death in 1936, Barnack's life's work had forever transformed the nature of photography.

  • 127 Cayley, Sir George

    SUBJECT AREA: Aerospace
    [br]
    b. 27 December 1773 Scarborough, England
    d. 15 December 1857 Brompton Hall, Yorkshire, England
    [br]
    English pioneer who laid down the basic principles of the aeroplane in 1799 and built a manned glider in 1853.
    [br]
    Cayley was born into a well-to-do Yorkshire family living at Brompton Hall. He was encouraged to study mathematics, navigation and mechanics, particularly by his mother. In 1792 he succeeded to the baronetcy and took over the daunting task of revitalizing the run-down family estate.
    The first aeronautical device made by Cayley was a copy of the toy helicopter invented by the Frenchmen Launoy and Bienvenu in 1784. Cayley's version, made in 1796, convinced him that a machine could "rise in the air by mechanical means", as he later wrote. He studied the aerodynamics of flight and broke away from the unsuccessful ornithopters of his predecessors. In 1799 he scratched two sketches on a silver disc: one side of the disc showed the aerodynamic force on a wing resolved into lift and drag, and on the other side he illustrated his idea for a fixed-wing aeroplane; this disc is preserved in the Science Museum in London. In 1804 he tested a small wing on the end of a whirling arm to measure its lifting power. This led to the world's first model glider, which consisted of a simple kite (the wing) mounted on a pole with an adjustable cruciform tail. A full-size glider followed in 1809 and this flew successfully unmanned. By 1809 Cayley had also investigated the lifting properties of cambered wings and produced a low-drag aerofoil section. His aim was to produce a powered aeroplane, but no suitable engines were available. Steam-engines were too heavy, but he experimented with a gunpowder motor and invented the hot-air engine in 1807. He published details of some of his aeronautical researches in 1809–10 and in 1816 he wrote a paper on airships. Then for a period of some twenty-five years he was so busy with other activities that he largely neglected his aeronautical researches. It was not until 1843, at the age of 70, that he really had time to pursue his quest for flight. The Mechanics' Magazine of 8 April 1843 published drawings of "Sir George Cayley's Aerial Carriage", which consisted of a helicopter design with four circular lifting rotors—which could be adjusted to become wings—and two pusher propellers. In 1849 he built a full-size triplane glider which lifted a boy off the ground for a brief hop. Then in 1852 he proposed a monoplane glider which could be launched from a balloon. Late in 1853 Cayley built his "new flyer", another monoplane glider, which carried his coachman as a reluctant passenger across a dale at Brompton, Cayley became involved in public affairs and was MP for Scarborough in 1832. He also took a leading part in local scientific activities and was co-founder of the British Association for the Advancement of Science in 1831 and of the Regent Street Polytechnic Institution in 1838.

  • 128 Jeanneret, Charles-Edouard (Le Corbusier)

    [br]
    b. 6 October 1887 La Chaux-de-Fonds, Switzerland
    d. 27 August 1965 Cap Martin, France
    [br]
    Swiss/French architect.
    [br]
    The name of Le Corbusier is synonymous with the International style of modern architecture and city planning, one utilizing functionalist designs carried out in twentieth-century materials with modern methods of construction. Charles-Edouard Jeanneret, born in the watch-making town of La Chaux-de-Fonds in the Jura mountain region, was the son of a watch engraver and dial painter. In the years before 1918 he travelled widely, studying building in many countries. He learned about the use of reinforced concrete in the studio of Auguste Perret and about industrial construction under Peter Behrens. In 1917 he went to live in Paris and spent the rest of his life in France; in 1920 he adopted the name of Le Corbusier, one derived from that of his ancestors (Le Corbesier), and ten years later became a French citizen.
    Le Corbusier's long working life spanned a career divided into three distinct parts. Between 1905 and 1916 he designed a number of simple and increasingly modern houses; the years 1921 to 1940 were ones of research and debate; and the twenty years from 1945 saw the blossoming of his genius. After 1917 Le Corbusier gained a reputation in Paris as an architect of advanced originality. He was particularly interested in low-cost housing and in improving accommodation for the poor. In 1923 he published Vers une architecture, in which he planned estates of mass-produced houses where all extraneous and unnecessary features were stripped away and the houses had flat roofs and plain walls: his concept of "a machine for living in". These white boxes were lifted up on stilts, his pilotis, and double-height living space was provided internally, enclosed by large areas of factory glazing. In 1922 Le Corbusier exhibited a city plan, La Ville contemporaine, in which tall blocks made from steel and concrete were set amongst large areas of parkland, replacing the older concept of city slums with the light and air of modern living. In 1925 he published Urbanisme, further developing his socialist ideals. These constituted a major reform of the industrial-city pattern, but the ideas were not taken up at that time. The Depression years of the 1930s severely curtailed architectural activity in France. Le Corbusier designed houses for the wealthy there, but most of his work prior to 1945 was overseas: his Centrosoyus Administration Building in Moscow (1929–36) and the Ministry of Education Building in Rio de Janeiro (1943) are examples. Immediately after the end of the Second World War Le Corbusier won international fame for his Unité d'habitation theme, the first example of which was built in the boulevard Michelet in Marseille in 1947–52. His answer to the problem of accommodating large numbers of people in a small space at low cost was to construct an immense all-purpose block of pre-cast concrete slabs carried on a row of massive central supports. The Marseille Unité contains 350 apartments in eight double storeys, with a storey for shops half-way up and communal facilities on the roof. In 1950 he published Le Modular, which described a system of measurement based upon the human male figure. From this was derived a relationship of human and mathematical proportions; this concept, together with the extensive use of various forms of concrete, was fundamental to Le Corbusier's later work. In the world-famous and highly personal Pilgrimage Church of Notre Dame du Haut at Ronchamp (1950–5), Le Corbusier's work was in Expressionist form, a plastic design in massive rough-cast concrete, its interior brilliantly designed and lit. His other equally famous, though less popular, ecclesiastical commission showed a contrasting theme, of "brutalist" concrete construction with uncompromisingly stark, rectangular forms. This is the Dominican Convent of Sainte Marie de la Tourette at Eveux-sur-l'Arbresle near Lyon, begun in 1956. The interior, in particular, is carefully worked out, and the lighting, from both natural and artificial sources, is indirect, angled in many directions to illuminate vistas and planes. All surfaces are carefully sloped, the angles meticulously calculated to give optimum visual effect. The crypt, below the raised choir, is painted in bright colours and lit from ceiling oculi.
    One of Le Corbusier's late works, the Convent is a tour de force.
