Abstract
1,134,940. Photo-copying apparatus; optical filter. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 21, 1966 [July 23, 1965], No.32747/66. Headings G2A and G2J. A photo-copying apparatus contains a gas discharge lamp, and a support through which are exposed the item to be copied and a copying material sensitive to blue and near ultraviolet radiation, said support carrying on a face thereof a layer comprising conductive tin oxide which reflects at least half of the incident heat radiation, and transmits at least half of the incident blue and near ultraviolet radiation. The support may be of quartz or glass, in the form of a rotatable hollow glass cylinder, and the layer is preferably on the lamp side thereof.
