摘要： A positive-working photosensitive mixture is disclosed, which comprises an o-quinonediazide as the photosensitive compound and a novolak resin, which is insoluble in water and soluble in aqueous-alkaline media, as a binder, said novolak resin being prepared by condensation of a mixture comprising m-cresol and 2,3,6-trialkylphenol with a carbonyl component, preferably in a solvent. The photosensitive mixture containing the above-described binder is distinguished by high thermal stability and by a low dark erosion rate when developed with a metal ion-free developer.

摘要： A process is described for the determination of the aging condition of an exhaust-gas catalyst for an internal combustion engine which is fitted with .lambda.-controlled regulation of the fuel/air ratio. In the process, the switching of the fuel/air ratio from rich to lean and vice versa is delayed and the content of the combustibles in the exhaust gas downstream of the catalyst is measured. With delayed switching, complete conversion of the exhaust gas only occurs when the catalyst still possesses its full oxygen-storage capability. Since the oxygen-storage capability decreases with increasing age of the catalyst, the degree of conversion or the proportion of combustible components arising in the exhaust gas when conversion is no longer complete is a direct measure of the aging condition of the catalyst. A catalyst can thus be replaced in good time before it is completely destroyed and before undesired components of the exhaust gas reach the atmosphere.

摘要翻译： 描述了用于确定用于配合λ控制的燃料/空气比的调节的用于内燃机的废气催化剂的老化条件的方法。 在此过程中，燃料/空气比从富燃料转换为稀薄，反之亦然，因此测量催化剂下游排气中的可燃物含量。 随着延迟切换，废气的完全转化仅在催化剂仍具有完全储氧能力的情况下才发生。 由于储氧能力随着催化剂年龄的增加而降低，当转化不再完全时，在排气中产生的可燃组分的转化度或可燃组分的比例直接测量催化剂的老化条件。 因此，可以在完全破坏催化剂之前及时排出气体的不期望成分到达大气之前及时更换催化剂。

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 rectangular label wherein a rectangular central portion is disposed between two rectangular sections having their rear sides provided with coats of adhesive. The front side of the central label portion bears imprinted information pertaining to the cost of developing of photographic film, the number of prints to be made from film, the price per print, the nature of film and/or the size of each print. The adhesive-coated sections are partially separated from the central portion by rows of perforations so that the central portion can be completely separated from the sections while the sections adhere to an envelope in order to at least partially close an open end of the envelope. Additional information may be imprinted onto the front side of at least one section to remain on the envelope, either as a bill to the dealer or as a bill to the customer. At least one of the adhesive-coated sections is provided with a fold line so that it can be readily folded over the open end of an envelope.

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.

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： The strip of originals to be copied is transported, prior to copying, through an evaluation station. There, the originals are evaluated with respect to density, color, copiability, or the like. A discrete strip-shaped information carrier is connected to the strip of originals and runs along the length of the strip of originals. The connection is effected either upstream of the evaluation station or at the evaluation station. Information derived from the evaluations performed at the evaluation station is entered upon the information carrier alongside the associated ones of the originals.
