摘要： The strip of originals is transported through an evaluating station where the originals are evaluated with respect to density, color, copiability, or the like. Information indicative of the results of these evaluations is manually entered upon a strip-shaped first information carrier in spatial coordination with the originals of the strip. Thereafter, at another location, the information on the first information carrier is transferred to a second information carrier. The strip of evaluated originals is then transported to a copying apparatus and there copied in accordance with the information on the second information carrier. The strip of originals itself can be utilized as the second information carrier.

摘要： An exposure control for use in photographic color printing apparatus has transducers which are sensitized in the additive primary colors and scan discrete areas of an original to transmit appropriate signals to integrator circuits which, in turn, transmit signals for regulation of the ratio of primary colors in printing light. The transducers further transmit signals to circuits which determine the presence of one or more areas of predominant color in an original and modify the signals which are transmitted to the integrators, either by weakening the intensity or by preventing the transmission of corresponding transducer signals. Detection of areas of predominant color can result in generation of signals which are used to contribute to determination of the total amount of printing light.

摘要： A film has a series of exposed and developed negatives. Each negative is scanned at a multiplicity of regions, and the densities of each region in the three primary colors are measured. A blue/red density differential is derived for each region by subtracting the red density of a respective region from its blue density. The neutral density of each region is calculated, and every region is assigned a coordinate on a plot of blue/red density differential versus neutral density. According to one embodiment, the blue/red density differential for each region having a neutral density equal to or greater than a limiting value is then subtracted from the blue/red density differential given by a characteristic curve for the film. The differences obtained in this manner are analyzed, at least for selected negatives, and the minimum difference for each selected negative is determined. The region corresponding to the minimum difference is that region of a negative having the maximum blue density. The blue/red density differential for the region of maximum blue density is compared with a pair of reference values derived from respective reference curves representing blue/red density differential as a function of neutral density. Based on the results of this comparison, each selected negative is classified as to whether it was exposed by artificial light or natural light, and is assigned an appropriate color correction factor for copying. Another embodiment is employed if the characteristic curve is found to lie near one of the reference curves. Here, the steps of subtracting blue/red density differentials and analyzing the resulting differences are omitted, and all negatives of the film are immediately classified as having been exposed by artificial light.
摘要翻译：一部电影有一系列暴露和发展的负面影片。每个负数在多个区域被扫描，并且测量三原色中每个区域的密度。通过从其蓝色密度减去相应区域的红色密度，为每个区域导出蓝色/红色浓度差异。计算每个区域的中性密度，并且在蓝色/红色密度差异与中性密度的图上分配每个区域的坐标。根据一个实施例，然后从具有等于或大于极限值的中性密度的每个区域的蓝/红密度差被从由薄膜的特性曲线给出的蓝/红密度差减去。分析以这种方式获得的差异，至少对于所选择的否定，并确定每个所选阴性的最小差异。对应于最小差的区域是具有最大蓝色密度的负区域。将最大蓝色密度区域的蓝色/红色浓度差异与从表示蓝色/红色密度差异的各个参考曲线导出的一对参考值作为中性密度的函数进行比较。基于该比较的结果，每个选择的阴性被分类为是否被人造光或自然光曝光，并且被赋予适当的颜色校正因子进行复制。如果发现特征曲线位于一个参考曲线附近，则采用另一个实施例。这里，省略减去蓝色/红色浓度差异并分析所得差异的步骤，并且将膜的所有负片立即分类为已经通过人造光曝光。

摘要： A color copying apparatus having a photoelectric color exposure control device is calibrated by making a copy of a calibrating original, which includes a gray stepped wedge, on a photographic copying material using an exposure determined by the photoelectric color exposure control device and assumed to be proper for achieving the desired density values in the developed image of the calibrating original. The density of the developed image of the gray stepped wedge is then measured in order to obtain actual density values, which are compared with corresponding desired density values. Finally, the photoelectric color exposure control device is adjusted for achieving the required exposure correction as determined during the comparison of the actual and desired values. The calibration is performed for each of the individual values so that correction of the control device is also achieved for each of the corresponding colors.

摘要： Color prints from transparencies which constitute frames or sections of universal film are made on printing paper by ascertaining the quotient or difference of integrated transmittance of the transparencies in green and red light, comparing the signal which denotes such ratio with a variable reference signal whereby the resulting comparison signal denotes the color temperature of light by which the respective transparency was exposed, and carrying out color corrections to depart from correction to neutral gray in dependency upon whether the ascertained color temperature denotes exposure in daylight or artificial light. The value of the reference signal is changed in such a way that the intensity of the ratio-designating signal which is necessary for generation of a comparison signal denoting the switchover point between the classification of transparencies into those respectively exposed by daylight and artificial light is lowered when the overall density of the transparency is lower and vice versa.

摘要： A first and second electrode web, of which at least one is transparent, are transported along respective paths both passing through an exposure station. A toner applicator upstream of the exposure station applies to the first web a uniform layer of toner suspension. Upstream of the exposure station, the coated first web and the second web are sandwiched to form a sandwiched film pack in which the toner suspension layer is located intermediate the two webs. The transport of at least that section of the webs constituting the sandwiched film pack at the exposure station is intermittent, but nevertheless the relative movement between the toner applicator and the first web is maintained uninterruptedly unidirectional and of uninterruptedly constant speed. At the exposure station, a color toner image is formed, on a whole-image basis, by projecting the whole image to be copied onto the toner suspension layer of the film pack section through the transparent web thereof while such section is at a standstill at the exposure station, and a corresponding color toner image is produced photoelectrophoretically. Downstream of the exposure station, the color toner image is transferred onto copy material.

摘要： Groups of several successive film frames of an exposed and developed photographic film are examined seriatim at an inspecting station which is located ahead of an encoding station or immediately ahead of the copying station in a photographic copying machine. An attendant examines the frames of a group at the inspecting station and actuates one or more buttons on a control panel in order to produce signals which are indicative of necessary adjustment of exposure controls for copying of certain frames. The buttons are actuated subsequent to depression of selected connecting knobs which form a row along the group of frames at the inspecting station and whose mutual spacing is less than the length of a frame; this insures that at least one knob is in register with each frame of a group at the inspecting station. The depression of a knob insures that the buttons on the control panel can transmit signals to the corresponding stage of a shift register. The stored signals are advanced through successive stages of the shift register, and the last stage transmits the signals to the encoding mechanism at the encoding station or directly to the exposure controls of the copying machine, always simultaneously with arrival of the corresponding film frame at the encoding or copying station.

摘要： A method, and an apparatus for carrying out the method, for purifying exhaust gases from internal combustion engines is provided. The engines having a catalyzer system which includes a first catalyzer and at least one second catalyzer, arranged downstream of the first catalyzer, for the conversion of HC, CO and NO.sub.x exhaust gas constituents. Exhaust gases flow through both catalyzers during the entire operating period of the engine. The first catalyzer is suitable for at least the catalytic conversion of HC and CO exhaust gas constituents. In a first step of the method, the first catalyzer is operated over-stoichiometrically during the cold starting phase in order to reduce the HC and CO emissions and, in a second step of the method with .lambda.-controlled stoichiometric exhaust gas composition, the catalytic conversion of the exhaust gas in the first catalyzer is at least largely de-activated and takes place in the second catalyzer. Substantially better endurance of the first catalyzer is attained for the same good reduction in the exhaust gas pollutants.
