Abstract

387,544. Focusing photographic enlargements. LAGORIO, A. VON, 49, Kufsteinerstrasse, Sch÷neberg, Berlin. April 13, 1932, No. 10599. Convention date, April 13, 1931. [Class 98 (i).] The image projected on the copy-plane A<1> A<11> by an enlarger indicated at V is sharply focused by observation of the grain of the image in an axially-adjustable magnifying eyepiece B which receives a portion of the image by reflection from an inclined mirror S. The eyepiece and mirror are mounted in a common casing G carried bv a stem H adjustable in a support T whose base is placed against the copy-plane A<1> A<11>.
