摘要： An apparatus and method for handling photographic film within the print-exposure section of a photographic printer. A mask matches the film frame (negative) and has a window for the passage of the exposure light. The mask also has holes through which air can be directed onto the film. A guide for the edges of the film parallels, and demarcates a gap with the mask. A source of air under either overpressure or underpressure supplies such air to the mask (4) and the film (1) through the air-direction openings (15). The air is supplied with overpressure while the film is being advanced. The air is supplied with underpressure while the print is being exposed to clamp the film.

摘要： A printer has a scanning station where the negatives of a film are scanned zone-by-zone. One or more of the negatives are subsequently printed at a printing station by directing a beam of light through the negatives and onto a first photographic copy material. An exposure control unit adjusts the color composition and intensity of the light beam on the basis of data from the scanning station. Once a negative at the printing station has been printed in this manner, a reflector is moved into the path of the light beam between the negative and the copy material. The reflector deflects the light beam to a video camera which scans the negative line-by-line and point-by-point to generate a series of electrical signals representing an image of the negative. The signals are sent to a memory where they are combined with information about the image. A cathode ray tube connected to the memory then prints the image line-by-line and point-by-point, together with the relevant information, on a second photographic copy material.
摘要翻译：打印机具有扫描台，其中电影的底片逐区扫描。随后通过将光束引导通过负片并印刷到第一照相复印材料上，印刷站中的一个或多个负片印刷在印刷站。曝光控制单元根据来自扫描台的数据来调整光束的颜色组成和强度。一旦以这种方式印刷了印刷站的负片，则反射器被移动到负片和复印材料之间的光束的路径中。反射器将光束偏转到摄像机，该摄像机逐行扫描并逐点扫描以产生表示负像的一系列电信号。信号被发送到存储器，在那里它们与关于图像的信息相结合。连接到存储器的阴极射线管然后将图像逐条和逐点地与相关信息一起打印在第二照相复印材料上。

摘要： An apparatus for rectilineal heating of a flat workpiece of thermoplastic material, so that the workpiece is bendable upon heating, includes first and second frame-shaped supports, the second support being positionable opposite the first support. The second support is pivotally mounted so that it can be swung upwardly away from the first support. The apparatus further includes first and second pairs of bars which are substantially juxtaposed with one another and displaceably disposed on the first and second supports, respectively, for gripping the workpiece, and at least one heating wire forming a heat source for contactless operation which is strung between at least one pair of the bars. The heating wire can be variably spaced on at least one side of and with respect to the workpiece.
