Abstract

387,320. Photographic apparatus. LUDWIG, W., 8, Tannengasse, Vienna. April 30, 1931, No. 12717. Convention date, Nov. 19, 1930. Void [Published under Sect. 91 of the Acts]. [Classea 97 (i), 98 (i), and 98 (ii).] An apparatus for copying, enlarging, contact printing, and opaque projection comprises a light-tight casing having a pair of reflectors on opposite sides in conjunction with auxiliary elements for the various processes. In the form shown the apparatus comprises a casing 1 fitted with reflectors 2 and open at the top and bottom. A copy frame 3 may be fitted in the upper opening with a bellows and lens 5 for enlarging and opaque projection. The frame 3 may be replaced by a hood-containing a light source for enlarging or projection of transparent originals. Contact printing may be effected by using a negative and a sheet of sensitive paper in the frame 3. It is stated that the apparatus may also be used for photography.
