摘要： A photographic copier has a first platform for supporting an original to be copied, and a second platform for supporting copy paper. A focusing system is disposed between the platforms and includes a plate which can be mounted at different distances from the platforms. The plate has a central opening which removably receives a tubular holder. The holder is supported in the opening by a ring which permits the position of the holder relative to the plate to be adjusted. Two lenses are removably mounted in the holder and serve to project an image of the original onto the copy paper. Different magnifications can be achieved in that the copier comes equipped with a variety of holders having different lengths, and a few selected lenses having different optical characteristics. The magnification is changed by simply interchanging holders and/or lenses, and adjusting the position of a holder to be used relative to the plate.

摘要： A copier has a movable housing which accommodates a support for an original to be copied, a source of illumination for the original, a lens system for forming an image of the original and a support for photosensitive material which is to receive the image. The housing has an opening in one of its sides and carries a hinged lid for lighttight sealing of the opening. A reflector is pivotally mounted inside the housing in the vicinity of the opening and can be moved between an operative position in which it intercepts the image from the lens system and an inoperative position in which it does not. When an image of normal size is required, the reflector is in its inoperative position and the image is projected onto the photosensitive material located inside the housing. When an image of large size is required, the reflector is brought into its operative position and the opening in the housing is uncovered. The reflector can then project the image through the opening and onto a large sheet of photosensitive material held on a wall or other suitable support.

摘要： A lengthy strip of originals is transported along a transport path. Positioned along the transport path are a plurality of copying stations, for simultaneous copying of plural successive originals. The originals are transported setwise or batchwise, thereby lowering the average transport time per individual original and increasing copying-machine productivity without the need to speed up the performance of other operations attendant to copying-machine operation. When originals are correctly spaced and all copiable, they are processed setwise or batchwise as just outlined. When not spaced in accordance with a standard and/or when not all copiable, the machine changes over to one-at-a time operation, disabling all but the most downstream copying station, until the arriving originals are again all copiable and spaced by the standard distance. During normal operation, a strip of print paper is advanced by an increment corresponding to the plural concurrently exposed originals. During one-at-a-time copying, the strip of print paper is advanced one print at a time, and the strip of originals is advanced until the next copiable original arrives at the most downstream station.

摘要： Successive frames of a web of photographic color film are subjected to objective examination during transport through an automatic evaluating circuit which may constitute a discrete prereader or a prereader which is integrated into a copying machine upstream of the copying station. The prereader furnishes signals which represent color and/or density correction data for reproduction of those film frames which can be properly copied only with a setting of exposure controls which deviates from the average setting for copying of the majority of film frames. The objective examination of all film frames is followed by a subjective examination which is performed by an attendant who inspects at least some of those film frames whose examination by the prereader resulted in the generation of correction signals. The attendant inspects the film frames at the copying station or at a second station which is located immediately downstream of a discrete prereader, and the attendant simultaneously observes the corresponding correction signals which are furnished by the evaluating circuit and are displayed close to the copying station or in register with film frames at the second station. The attendant can approve, modify or cancel the correction signals, and can also initiate the generation of additional signals, e.g., to identify those film frames which are unfit for copying.

摘要： An automatic prereader for exposed and developed frames of a web of spliced-together photographic color films is preceded by a first station and followed by a second station at the first of which groups of successive frames are subjected to a first subjective examination by an attendant and at the second of which some of the frames are subjected to renewed subjective examination by the same attendant. The attendant actuates one or more pushbuttons upon examination of frames at the first station to produce signals which denote improperly oriented frames, frames which were exposed in artificial light and/or frames which are unfit for copying. Such signals are used to modify signals which are furnished by the automatic prereader. The modified and unmodified signals which are furnished by the prereader are examined for intensity, and those signals whose intensity is outside of a preselected range are displayed at the second station so that the attendant can observe such signals simultaneously with observation of the respective film frames and is in a position to initiate the generation of additional signals which are used to modify or erase the corresponding signals from the prereader before the signals are transmitted to the exposure controls of a copying machine.

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.

摘要： An exhaust-gas filter, for example a soot-particle filter, has a filter element which has inlet passages for the raw gas and outlet passages for the clean gas. In order as far as possible to prevent clogging of the filter over the running time caused by deposits on the filter walls, the raw-gas passages are configured with a larger cross-section than the clean-gas passages.

摘要： A method for electronic reduction of the contrast of video images as early as during recording provides electronic brightening of the shaded zones of a video image in a camera as early as during recording while maintaining the detail contrast even in the brightened regions. A blurred diffuse image of the motif is produced on the image sensor in the camera by the objective and the electronically alterable diffusion element, and is stored in a frame store. The black and white contrast of the mask is determined in the evaluation circuit, and a control variable is generated pixel-by-pixel from this. The focused video image which is subsequently produced on the image sensor when the diffusion element is switch to be crystal-clear is read and is amplified or attenuated pixel-by-pixel such that the shadowed parts are brightened and/or the bright zones are attenuated.

摘要： An exposure of a color film is scanned at a multiplicity of points in each of the primary colors. The color compositions of the points are evaluated to identify color compositions characteristic of skin tones, and a color space is created based on these color compositions. Scanned points whose color compositions lie in the color space undergo an examination to ascertain whether or not they actually represent skin. The examination is concerned primarily with the positions of such scanned points within the exposure and secondarily with density differences between the points and specified zones of the exposure, density differences between adjacent points, and the nature of any groups formed by the points, only those scanned points which actually represent skin are considered when calculating the amount of copy light for the exposure in each primary color.
