Abstract: A web of copying material is transported on-edge through an exposure-station web guidance system provided with a masking system which includes stationary and shiftable transverse-edge framing plates. The projected image of a first longitudinal-edge reference line on the copy table supporting the original is brought into register with a corresponding reference line of the masking system. The projection scale is adjusted to cause the format-breadth of the projected image to be at most slightly smaller than the format breadth of the web, but in no event greater. The projected image of the first transverse edge of the original is brought into register with the edge of the stationary framing plate, and then that of the second transverse edge with that of the shiftable framing plate. This registration is effected by sensing infrared-light images of the dark-light transitions associated with the transverse edges of the original. An exposure is performed.

Abstract: A stack of documents are transported one-at-a-time, under control of an automatic machine. A machine readable card is inserted between preselected documents in the stack. When the transport detects a passage of the card through the transport system, the machine is commanded to perform a specific function. The exemplary machine described herein is a microfilm camera, and the illustrative functions are two side copying and batch or file marking.

Abstract: In electrophotographic copying apparatus utilizing a photoconductive belt having markings regularly spaced apart on its back side for control of the copying operations by moving past a detector comprising a light source and a photoelement to generate signal pulses, the detector is made to perform reliably notwithstanding variations of the sensitivity of the photoelement, or of the light emission, by the provision of a circuit for emitting a detector signal proportional to the amount of light sensed by the photoelement together with a signal modifying circuit that maintains an output signal level corresponding to the average value of the detector signal and a control circuit responsive to the output signal level for controlling the intensity of the light source.

Abstract: Conventionally, color films must be used with the light source or illumination for which it was designed, such as for natural daylight, fluorescent-light or tungsten-light or, if used with another light source, a suitable conversion filter must be placed over the camera lens. However, an improvement in the emulsion of the film provide an improved type of film with which good printed images are available through a mere correction during printing of the film. The present invention provides a method and a device for detecting and recording the type of illumination through detection of their spectral properties and detection of existence of a flickering noise due to an alternating voltage of the commercial power supply, and a system for an automatic film development.

Abstract: Apparatus for the application of different first indicia to successive envelopes for exposed photographic films and for the application of related different second indicia to associated films has a first marking unit which imprints first indicia onto successive envelopes and a second marking unit which exposes second indicia onto unexposed portions of films. The second unit is adjusted in automatic response to monitoring of adjustment of the first unit, and the two units can be actuated to apply related first and second indicia to an envelope and to the associated film only when the envelope and the film assume predetermined positions with respect to the corresponding units. The positions of successive envelopes and successive films are scanned by discrete first and second photoelectric cells. The first unit is adjusted by the first cell or in automatic response to completion of application of first indicia to an envelope.

Abstract: In a telecine equipment of the flying spot cathode-ray tube type with an oscillatory mirror, markers associated with the frames of a film are illuminated with a light spot of small dimensions, which substantially follows the motion of the marker associated with the frame being scanned. This is obtained by means of a small fixed light source, which is used for scanning the path followed by the marker associated with the film frame being scanned, using the same optical channel as for the frame scanning. This same optical channel, used in the reverse direction by means of a fixed mirror located behind the film, forms the image of the illuminated marker.

Abstract: Apparatus for exposing an image of a desired pattern, such as a lead frame pattern for producing lead frames of IC devices, with a predetermined pitch on a photosensitive beltlike material consisting of a film carrier and a photoresist-coated metallic foil laminated on the carrier.Apparatus typically comprises a first means for positively supporting and accurately positioning the beltlike material at an exposing position, a second means for intermittently conveying the material and a third means for photoelectrically detecting the amount of the movement of the beltlike material to control the first and the second means.

Abstract: Apparatus for positioning exposed and developed photographic roll films in a copying machine has a base which is formed with an exposure window and supports a removable cover, an advancing roll for photographic films, a first set of claws which can enter the perforations of a section of a roll film when the section is inserted and moved lengthwise by hand, and a second set of claws which can be used to position manually inserted webs of different films film webs which are bonded to data-carrying strips. The cover thereby retracts or depresses the first set of claws so that they cannot interfere with automatic transport of roll films. The claws of the second set are held in retracted positions by a removable insert which carries the first set of claws and the advancing roll and which is replaceable by a second insert when the apparatus is to position manually inserted different films which are bonded to data carrying strips.

Abstract: A film strip controller for exposed and developed photographic roll film adopted to be used with a photographic printing apparatus employing a roll film strip transport drive using slip clutches, includes a magnetic brake assembly responsive to signals generated as a result of varying light intensity incident upon a plurality of photosensitive detectors. The brake assembly stops the roll film being transported through the controller with each negative image on the film strip in proper registration and locates the negative in the proper plane so the shutter of the associated photographic printing apparatus can be operated to expose a positive print of the negative. Operation of the shutter may release the brake of the controller allowing the film to continue to move through the film strip controller until stopped by the brake means for the next negative.

Abstract: A microfilm instruction system provides detailed service instructions for diagnosing and repairing complex electronic instrumentation. Troubleshooting procedures are recorded on microfilm along with a series of programmed instructions for directing the service repairman step-by-step to pinpoint the source of the problem and to make the necessary repair. Each frame of microfilm containing a sequence of question sets which appear upon the display plate of the microfilm viewing system further provides a corresponding series of response switches also located on the microfilm viewing system. Each of the questions relate to a possible condition for the malfunctioning electronic apparatus to be repaired and each series of questions requires an affirmative or negative response by means of the response switches.

Light splitting means is provided in the optical path of image projection so as to split part of the image light projected through the lens means to travel toward the viewing screen and the photosensitive medium so that only part of the image light projected upon the viewing screen is directed to the photosensitive medium.

Abstract: The variation in transparency along the surface of an original is detected and a corresponding transparency-indicating signal is generated. The spectral components of the transparency-indicating signal having frequencies above a predetermined frequency associated with sharp images are integrated to form an integration signal corresponding to the time integral of these higher-frequency spectral components. The determination of whether the original bears an image whose sharpness warrants copying of the original is made by comparing the integration signal against a reference signal.

Abstract: In a photocomposition machine environment the apparatus and method show the concept of advancing the photosensitive material into position normally occupied for composition of text. The known apparatus and method are then modified by providing reverse leading for the paper and re-advance to the starting point followed by composition of a second column lateral to and aligned with the first column. A particular advance in the art is the ability to compose a complex mathematical formula with greatly simplified software using the improved hardware.The point of reference is established by a sensor which is activated upon advance of the paper to the sensor and therefore reversal and re-advancement of the paper will cause an exact repositioning of the paper for each column.
