Abstract: The present invention relates to a system for the optimization of a copying light profile during copying of photographic originals in a photographic copier. The photographic copier comprises a light source for producing copying light, a number of light conducting means for guiding the copying light along a light path, and a local transmission modulator. An element with a known transmission profile is provided in the light path for being shone through, whereby no photographic original to be copied and of unknown transmission profile is found in the light path, and furthermore a transmission profile specific for the local transmission modulator is provided. The resulting copying light is measured broken down by area, and the profile of the copying light is measured and compared with a desired copying light profile. Based on this comparison, the transmission profile preselected for the copying process is optimized.

Abstract: During the processing of an order in a photographic printer, a developed copy film strip can be scanned negative by negative and point-by-point in a scanning station of the printer. From the scan signals, density values for exposure time determination in three partial colors and details on the image field number of the scanned negative can be obtained, and these data are stored in a memory, coordinating the determined three partial exposure times with the corresponding image number. All negatives of the copy film strip are exposed successively on photographic paper on an enlarged scale, using the determined exposure times. In a further step, a number of successive negatives of the film strip are exposed on full-scale or reduced scale in matrix form onto a single sheet of said photographic paper.

Abstract: In a part (2) comprised of a slightly elastic material, a collector structure (11) is arranged above a collecting cavity (19) provided with an outlet (7). The collector structure (11) is comprised of two side pieces (11a, 11b) in the form of zigzag-shaped prominences. The structure delimits a wet zone (22), while a moist zone (23) is delimited by the lateral regions (18a, 18b) of the border (18) together with a rear bead (17) and a front bead (15). The collector structure (11) is placed between the labia minora and labia majora of the woman, while the elements delimiting the moist zone come to lie outside the labia majora. The inventive urine collector enables incontinent women to freely move about without risk of their garments being contacted with urine.
