This latter result was achieved by passing the light from each lamp through a coloured gelatine screen that could easily be placed in front of the lamp when required. For the ramp, each lamp was surrounded at its base by a horizontal pulley whose circumference could be considered divided into three parts. The first third remained free, the second carried a vertically cylindrical red gelatine screen, and the third was fitted with a similar blue gelatine screen. A cord passed, as shown in fig. 89, alternately in front of and behind all the consecutive lamps, so that when it was pulled, it caused two neighbouring lamps to move in opposite directions; but the screens were positioned so that, with all the lamps initially exposed as shown in the figure, a single movement of the cord brought all the red screens or all the blue screens in front of them.","language":"en"},"type":"monolingualtext"},"datatype":"monolingualtext"},"type":"statement","qualifiers":{"P47":[{"snaktype":"value","property":"P47","hash":"288d2f8ae36e5c57479959cddd9d339fca35a4ef","datavalue":{"value":{"text":"English translation of the above","language":"en"},"type":"monolingualtext"},"datatype":"monolingualtext"}]},"qualifiers-order":["P47"],"id":"Q39061$d1c01f3d-4aa9-1176-5cdb-924fbb3bf60e","rank":"normal"},{"mainsnak":{"snaktype":"value","property":"P47","datavalue":{"value":{"text":"For the lamps of the herses (fig. 90), the arrangement of the screens was reversed, with the lamps inverted; in addition, the control cord operated in a different way.
