Abstract

211,169. Heimstõdt, O. Feb. 12, 1923, [Convention date]. Optical-projection apparatus for obliquely projecting dia-positives, wherein the optical axes of the condenser and projection lens are inclined to one another, is mounted on a support u which can be held at an angle to the projection screen, and the supports for the projection lens o and the holder p for the dia-positive are capable of being adjusted so that their principal planes are parallel to the screen. As shown, the support u is hinged to a base board a and is held by a quadrant guide b and thumb screw w. Joints l are provided in the supports for the projection lens o and holder p-
