Abstract: Envelopes which are about to receive developed photographic films and/or prints are advanced toward a stacking station in a predetermined orientation and each envelope is provided with one or more fold lines extending in the direction of advancement of envelopes. The fold lines serve to straighten the envelopes which are delivered in rolled, creased and/or otherwise deformed condition such as could interfere with predictable stacking of envelopes in a predetermined sequence which is necessary to ensure that each envelope receive a proper set of film frames and/or prints for shipment or delivery to the parties whose names and/or addresses appear on the envelopes. The fold lines straighten the originally deformed envelopes (which are in random distribution with non-deformed envelopes) for an interval of time which suffices to ensure proper stacking, even if the envelopes exhibit a pronounced tendency to reassume their deformed state.

Abstract: Apparatus for shifting X-ray films in a magazine wherein films having different sizes form a stack and which as a straight or corner-shaped internal stop for properly oriented films. The apparatus has a frame which is reciprocable toward and away from the magazine and carries two or more pivotable links each of which supports one or more driven wheels movable into frictional engagement at least with the outermost film of the stack to shift the engaged film toward and against the stop. Properly oriented films are withdrawn from the magazine by one or more suction cups which share the movements of the links relative to the magazine. The wheels are rotated by a common prime mover.

Abstract: A photographic copier has an adjustable masking device for masking a master to be reproduced. To determine whether masking is required and, if so, the degree of masking, the density of the master is measured and is then forwarded to a logic circuit which can make the determination. In a first mode of operation, masked and unmasked images of the master are displayed side-by-side on a pair of monitors so that an operator can make adjustments to the mask calculated by the logic circuit. The operator here controls the copying cycle. In a second mode of operation, the copying cycle is automated and the logic circuit decides whether masking is required by calculating a degree of masking and comparing the degree of masking with a relatively low reference value set by the operator. The master is copied without a mask when the calculated degree of masking is less than the reference value. If a copy made by masking is unsatisfactory, the operator can adjust or deactivate the logic circuit and make a new copy.

Abstract: A process for a common deflection of at least two light beams having different wavelengths, wherein the deflection is carried out by means of an acousto-optical crystal, is characterized in that color-dependent beam dividers and deflection units are inserted in the beam path of the, at least two, light beams of different colors in such a way that deflection angles are compensated by properly adjusted longer beam paths, so that all beams coincide at a predetermined distance from the deflecting crystal.

Abstract: Light is passed through a negative located in a primary optical path and towards a band of copy material disposed in the path. A reflector is movable into the primary path so as to deflect the light into a secondary optical path. A mat, transparent plate is situated in the secondary path. The plate is situated in a plane which is a conjugate of the plane of the copy material with reference to the reflector when the latter is in the primary path. A sharp image of the negative is formed on the plate. Light passing through the plate is deflected into a tertiary optical path by a second reflector. The light entering the tertiary path is sensed by a video camera which then causes the image on the plate to be reproduced on a monitor for evaluation prior to copying.
