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： Apparatus for convoluting a web of photographic paper issuing from a copying machine onto a core of a cassette which is movable to a predetermined position with reference to the machine has an operating device which can deactivate the web catcher mechanism in the cassette in response to detection of adequate attachment of the leader of the web to the core. The catcher mechanism serves to guide the leader of the web into engagement with the core and is activated on movement of the cassette to its predetermined position. The circuit which monitors the engagement between the leader of the web and the core compares the peripheral speed of the core with that of a rotor which is installed in the machine and whose peripheral speed is lower than that of the core prior to completion of attachment of the web to the core. The operating device utilizes an electromagnet or an electric circuit whose condition is changed by the monitoring circuit when the attachment of the leader of the core is completed, and such change in condition initiates the deactivation of the catcher mechanism. The rotor advances the web toward the core during attachment of the leader to the core but is rotated by the web when the attachment is completed.

摘要： Azo dyes corresponding to the formula (II): ##STR1## wherein G represents a group capable of forming a 5-membered chelate ring and R.sup.5 represents aryl or a thienyl group, combined with metal ions, in particular copper or nickel ions, to form stable azo dye-metal complexes which have advantageous spectral properties. They are therefore particularly suitable for the production of highly light-fast cyan images, e.g. by the Ink-Jet process, in which they may be used directly in the form of colored inks, or by the dye diffusion transfer process, in which they are released image-wise from corresponding dye-releasers in the course of development and transferred to a dye-absorbent layer.

摘要： Azo dyes corresponding to the formula (I): ##STR1## wherein R.sup.1 represents a releasable group, R.sup.2 represents H, halogen or sulphonyl, R.sup.3 and R.sup.4 represent H or groups not capable of chelate formation, and Q represents a group for completing a phenyl or naphthyl group,combine with nickel ions to form stable azo dye-metal complexes which have advantageous spectral properties. They are therefore particularly suitable for the production of highly light-fast magenta images, e.g. by the ink jet process, in which they may be used directly in the form of colored inks, or by the dye diffusion transfer process, in which they are released imagewise from suitable dye-releasers in the course of development and transferred to a dye-receptive layer.

摘要： Apparatus for transferring sheets from a relatively wide or relatively narrow stack of sheets into a transporting device has a pair of suction cups which engage the leader of the topmost sheet in the stack and turn it through 90.degree. so that the leader becomes separated from the leader of the sheet therebelow. The suction cups are thereupon raised to the level of the nips of driven advancing rolls in the transporting device to move the leader into a plane which includes the nips and is parallel to the planes of sheets in the stack, and such leader is introduced into the nips so that the advancing rolls engage the leader while the latter becomes detached from the suction cups. The suction cups engage only a portion of the leader of a relatively wide sheet, and the remainder of the leader is flexed with the engaged portion to ensure that it enters a path which is defined by additional advancing rolls of the transporting device simultaneously with entry of the engaged portion of the leader into the nips of the driven advancing rolls. The apparatus can be used with advantage for removal of successive topmost X-ray films from a stack of films regardless of the width and/or height of the stack. The suction cups descend from the level of the nips to the level of the topmost sheet in the stack as soon as the transfer of the preceding sheet is completed and along a path such that each of a series of successive properly stacked sheets is engaged at the same distance from its leading edge.

摘要： An arrangement for introduction of a film magazine into a film-processing device has a housing which defines an inlet slot through which the film magazine is inserted. The film magazine has a film stack carrier provided with at least one opening for removal of the film and a casing member which is movable with respect to the film stack carrier. In order to guarantee the light-tight shielding during the introduction of the film magazine, a shutter is provided along the inlet slot which is parallel movable within the interior of the housing and serves as support for the film stack carrier. The shutter has a circumferential edge which cooperates with a respective circumferential edge of the housing for providing a first light-tight shielding and a second light-tight shielding is provided through cooperation of the circumferential edge with a respective groove provided in the casing member.

摘要： A copying machine admits a web of freshly exposed photographic paper directly into a cassette whose core engages and convolutes the web therearound. The progress of engagement between the leader of the web and the core is monitored by comparing the peripheral speed of the core with the peripheral speed of a rotor forming part of an advancing roll for the web and receiving torque from a variable-speed motor which also drives the core. The peripheral speed of the rotor increases when the leader of the web is adequately attached to the core, and this is detected by a circuit having first and second photoelectronic monitoring devices which respectively monitor the peripheral speeds of the rotor and the core. The signals which are generated by the monitoring devices are processed, and the processed signals are used to change the speed of the variable-speed motor, to deactivate a catcher mechanism which directs the leader of the web toward the core and assists in the establishment of adequate engagement between the leader and the core, to change the supply of energy to the motor as the diameter of convoluted web on the core increases, and/or to actuate an alarm device when the completion of attachment of the leader to the core is unduly delayed.
