    摘要： Video monitor images which include at least one object showing multiple dimensions are superimposed with CAD images which include the corresponding designed dimensions of the object. Such images are substantially overlaid, aligned and focused so that the CAD designed dimensional images substantially match the corresponding video monitor images and any differences between the dimensions of the video images and the corresponding CAD designed dimensions of the CAD images may be readily determined.

    摘要： An exposure control system for a photographic camera employing a scanning type shutter that includes a pair of cooperating shutter blade elements automatically compensates for exposure altering variations in shutter blade element speed that may occur from one exposure interval to another. The exposure control system includes an encoder to provide information on the actual position of the shutter blade elements as a function of time during an exposure cycle. The encoder generates a series of pulses representative of relative blade element position as the blades are moved during the exposure cycle. The time between these pulses is measured and directly converted into a signal representative of shutter blade element speed or velocity. This shutter blade speed signal is then employed to alter the duration of an exposure interval to compensate for any shutter blade element speed variations.

    摘要： L'invention se rapporte à des composés produisant des couleurs et comprenant au moins deux groupes cycliques 1,3-soufre-azote et au moins deux fractions produisant des couleurs, à savoir des colorants purs ou des intermédiaires de colorants, capables de libérer les fractions formant des couleurs lors d'une séparation en présence d'ions d'argent ou d'un complexe d'argent soluble. Les composés produisant des couleurs sont utilisés comme matériaux formant des images dans des procédés photographiques en couleur.

    摘要： During manufacture each frame of a film strip has one portion masked while the frame is exposed to light. Said light impinges on a second portion of the frame to form a latent image. The film strip is mounted within a camera where the previously unexposed portion of the frame is exposed to a second image bearing light while the pre-exposed portion of the frame is masked from said second light. the strip of film is removed from the camera to develop the two latent images as a single photograph.
