Patent ES-467041-A1 (ES)
Title: Photographic type composing machine
IPC: B41B17/00
Filed: 1978-02-16
Abstract: The machine provides access to a relatively large number of different characters located on relatively large spinning discs or drums. The characters are located in arrays such as concentric rows on a disc. A plurality of lenses is mounted on a lens carriage, and one or more light sources is mounted on a flash-lamp carriage. Character spacing is determined by motion of the lens carriage and/or the lamp carriage. Array selection is performed by motion of the lamp carriage, and/or motion of the lens carriage. Composition of lines or columns of characters taken from a relatively large number of different arrays, such as would be the case in type composition using Chinese ideographs, is speeded considerably by controlling the order in which the characters are projected so that the lens carriage need not reverse its direction of motion during composition of a line. A simple mechanism is used to change lenses for size changes by the selective use of stops at the ends of the travel path of the lens carriage. Two discs or drums can be used alternatingly to increase the number of characters available. A simple attachment is provided for composing long lines of enlarged characters for composing headlines and the like. This avoids the necessity of providing a separate headlining machine. Another simple attachment is provided for inserting Pi characters. This attachment makes use of the lamp carriage and drive mechanism in selecting the Pi characters for projection. A method which is especially useful in economically producing large matrix discs is described. An economical "floppy" or flexible film disc also is described. A system and method are described for electronically detecting base-line and spacing errors in the characters on the character matrix, storing the errors, and correcting the errors electronically during projection of the characters onto the photographic film.

Title: Imaging of a sectional layer of a three-dimensional object
IPC: G03H1/06
Filed: 1979-03-09
Abstract: In tomosynthesis, plural sources 1, 2, 3, 4, form shadowgraph images P1, P2, P3, P4 of an object with features A, B from different perspective directions. In synthesising a selected sectional image the images P1 ... P4 are superposed with appropriate shift to cause corresponding image point locations defining the selected layer to overlap and reinforce one another. The present invention reduces the effect of background image points from other layers by a process of selection or enhancement logic which is applied to each set of overlapping local image values relating to a corresponding image location in the selected section, to allocate to that location a related image value or a substantially zero value depending on whether the image detail is assessed as lying in the selected section or not. In one embodiment, Figure 4, the images P1 ... P4 are each scanned in 5 lines Z1 ... Z5 to form a corresponding video signal 9 which is applied to a parallel storage arrangement with different shift delays O, DELTA t1, DELTA t2, DELTA t3. The overlapping signal values at each location Pn1 ... Pn4 are processed by an analyser 10a which causes a control stage 10b to transfer an image signal to an output register Sn for display only when a signal exceeds a threshold in all or most component images. Alternatively (Fig. 7 not shown) images P1 ... P4 can be multiplied together using a Titus tube, polarised light beam and associated television equipment.
