Dans un dispositif pour libérer une feuille de film (67) adhérant à la face intérieure de son support (19i) sur la partie supérieure (19c) d'une cassette de film pour rayons X (19) lorsqu'on fait pivoter vers sa position ouverte ladite partie supérieure (19c), un agencement à leviers multiples du type tringlerie (60, 61, 62) est articulé à une barre (10) permettant l'alignement et le positionnement de la cassette de film pour rayons X (19). Le dernier élément (62) dudit agencement porte un ajutage d'air (70) ainsi qu'un axe (62a) et s'étend jusque dans la trajectoire de mouvement de la partie supérieure de cassette pivotable (19c). Lorsque l'on fait pivoter cette dernière vers sa position ouverte, sa face terminale (19h) coulisse le long de l'axe (62a) jusqu'à ce que la partie supérieure de cassette (19c) repose sur le dernier élément (62). Lors d'un nouveau mouvement de pivotement vers la position ouverte, l'agencement à leviers multiples (60, 61, 62) pivote le long de l'axe (62a) et est maintenu au moyen de ce dernier au niveau de la surface terminale (19h) de la partie supérieure de cassette (19c). Par suite, l'ajutage d'air (70) se trouve dans sa position fonctionnelle à n'importe quel angle d'ouverture de la partie supérieure de cassette pivotante (19c). Le jet d'air destiné à libérer la feuille de film (67) est dirigé approximativement tangeantiellement pour passer devant le bord antérieur (67a) de la feuille de film (67) adhérant à la surface intérieure de son support (19i) sur la partie supérieure de cassette (19c).
摘要:
Process and system for producing color images and/or multispectral images in which an optical arrangement (3) images a scene on a CCD image sensor (2), said sensor being covered by a mosaic filter with a periodically repeating basic pattern (GM). A following analog/digital converter (5) produces digital signals from all pixels p ij of the CCD image sensor (2). The basic pattern (GM) consists of a minimum of five different filter elements. In addition, an image memory (6) is provided which is divided into image memory levels (B 0 , B 1 ,....,B nF ). The process comprises the following steps: storing of values (wert[i][j][0]) of each individual pixel (pij) of the CCD image sensor (2) in a dedicated level B0 of the image memory (6), said values being determined by the CCD image sensor (2) and converted by a following analog/digital converter (5) into digitial values; determining an "unfocussed image" in the following way: for each color f and for each pixel p the neighboring pixels of color f are measured, their values read from B0 and combined to arrive at a weighted average value; storing of values (wert[i][j][f]) for all the different filter elements on the CCD image sensor in dedicated image memory levels (B1, B2,....,BnF); calculating final color values (C1,C2,......,CnF) by means of additive image sharpening; and storing the final color values (C1,C2,......,CnF) in dedicated image memory levels (B1, B2,....,BnF).
摘要:
The apparatus for displaying images located on an exposed photographic film (6) on a viewing unit (15) consists of a keypad (40) for operating the apparatus and selecting the functions stored in the apparatus, a receiving means for a film cassette (3) in which the exposed film (6) containing the images is wound, a transport means (7, 7a, 11) for moving the film (6) from the film cassette (3) to a takeup cylinder (5), an illumination unit (4), a deflection mirror (12), and an optical lens (8) for forming an image on a CCD sensor (9), as well as circuit means (24, 25) for controlling the operation of the apparatus, and storage means (23) for saving the scanned images or for user inputs via the keypad (40). The apparatus is configured, together with the viewing unit (15), as a movable, portable apparatus that is independent of an external energy supply. The viewing unit (15), which is a color LCD display, is integrated into the apparatus and can be pivoted about a bearing (16) from an operating position into an inactive position.

The device serves for the translatory motion with accuracy of feed of a slide (11) movable by means of a threaded spindle (14) fixedly mounted for rotation, wherein a ring nut (16) axially movable on the threaded spindle is connected to the slide (11), by providing a compensating coupling (10) of cardanic action between the ring nut (16) and the slide (11). In particular, the compensating coupling (10) consists of a body (17) which is circular or square in cross section and has a central axis (18), in which body two universal joints (1a, 1b and 2a, 2 b or 3a, 3b and 4a, 4b) arranged one behind the other are composed by diametrically mutually opposed radial slits (A, B; E, F) and by further diametrically mutually opposed radial slits (C, D; G, H) which are staggered axially and through 90 angular degrees. The slits in each case composing a universal joint are arranged at an acute angle to the central axis (18) of the body (17). The four joints of a universal joint are on a plane (24, 25) extending perpendicular to the central axis (18) of the body (17).
摘要:
A highly precise linear transport apparatus consists of a driving motor (6), a clockwise and counter-clockwise rotatable drum (10) driven by said motor and a linearly movable transport table (2) having a first fastening element (4a) and a second fastening element (4b), each of said elements being attached to one end of a flexible, non-stretchable belt (12a, 12b). Two flexible, non-stretchable belts (12a, 12b) are wound around the drum (10). Said belts are axially positioned on the cylindrical surface of the drum (10) and are wound around the drum (10) at least once. The first fastening element (4a) and the second fastening element (4b) are L-shaped elements (22,24). The free ends of the belts (12a, 12b) are attached to the short arms (22b, 24b).
