Abstract: A silver halide color photographic film element and more particularly a color motion picture projection film element is provided comprising a transparent thermoplastic film support having a subbing layer unit, coated thereon at least one color forming hydrophilic layer and protective layer, characterized in that at least said subbing layer unit comprises at least one light-stabilizer, preferably absorbing ultraviolet radiation, and at least one chemical compound having reducing properties.

Abstract: A photographic exposure apparatus includes a lamp housing for a metal-halide discharge lamp for exposing a light-sensitive film to an image-bearing sheet when the lamp is energized to full power, a shutter for closing the lamp housing while the lamp remains energized at a lower power level in stand-by condition, and a control unit for energizing of the lamp in standby condition in such a way that, while being maintained at reduced power, the lamp is intermittently energized at high power during short intervals, e.g. in pulses, to thereby substantially prolong the working life of the lamp.

Abstract: A method and an apparatus wherein wedge print density value comparisons made with the aid of a photoelectric densitometer give indications of the developing activity of a photographic developer which are independent of the temperature of the photodetector.

Abstract: The present invention relates to a machine for accurately cutting documents from a web of transparent material carrying one or more opaque documents, which machine comprises a punch-type cutter which is mounted for pivotal and lateral movement and capable of automatic positioning for accurately cutting a well-defined portion of the web so as to provide series of individual documents of predetermined size. The machine is provided with a first detector for detecting the arrival of an opaque document on the web at the cutting zone, a control responsive to the detector for arresting the movement of the web, other detectors for determining the relative lateral and angular position of the document on the web with respect to the cutter and a control responsive to the other detectors for displacing the cuttering laterally and angularly to bring the same into a predetermined position with respect to the document.

Abstract: Subtle streaklike defects are detected in running webs and sheets by transversely scanning distinct lateral sections of the webs or sheets by means of lines of radiant energy extending parallel with the direction of movement of the webs or sheets. Transmitted or reflected radiation is received on corresponding photocells that move synchronously with the lines of radiant energy. During each scan of each section of the webs or sheets, a large number of comparisons occur between the output signals of each photocell at a given first lateral position and at a second lateral position that is separated from the first one by a distance that is of the order of magnitude of the width and preferably half the width, of a streaklike defect to be identified.

Abstract: Subtle streaklike defects in running webs and sheets are identified by transversely scanning adjacent lateral sections of the webs or sheets by means of radiant energy means. Transmitted or reflected radiation is received on corresponding photocells that produce measurement signals that are representative of a defect in the webs or sheets. The signal-to-noise ratio of the measurement signals is increased by multiplicative correlation, on the condition that the ratio of the signal component V.sub.d to the effective noise component V.sub.n of the measurement signal V.sub.m is greater than one.
