Abstract

953,091. Film holders. LAWES BROS. Ltd. Jan. 29, 1963 [Jan. 29, 1962], No. 3263/62. Heading G2C. A film holder comprises two glass plates 3, 4 mounted in frames 1, 2 which are held together by permanent magnets 7, 8 engaging various members 5, 6. The ferrous members may be replaced by magnets. The magnets may be resiliently mounted so that small differences in film thickness may be accommodated. Dyeline printing paper which may be subjected to a light image over a considerable period of time may be used in the film holder.
