METHOD AND APPARATUS FOR EDITING MOTION PICTURE FILM

... 1320601 Cine apparatus; editing prepared films POLAROID CORP 14 July 1971 [17 July 1970] 33106/71 Heading G2C and G2E A method of and apparatus for projecting an edited cine film that does not involve the physical removal of unwanted film lengths. The unwanted lengths are delineated by data on a track on the film, a sensing device detects this data and issues signals in response, the signals acting on a film drive control which is caused to project the desired film lengths at a normal projection speed and to rapidly pass over the unwanted lengths, preferably with the light source obscured. As shown in Fig. 1 film F in a cassette 10 is projected by means of lamp 26, mirror 28 and lens 14, the undesired images being distinguished by recording electromagnetically data on a track provided on the film F. This recording is performed by head 72. When the film is subsequently projected, head 72 also senses this data. When sensed it provides an input to the circuit, shown in Fig. 5, which activates ...

A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film -such as (for example) the film manufacturer, the camera user, the dealer and photofinisher- is carried via plural longitudinal magnetic tracks on the film that begin and end within each individual frame. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame. The photofinisher-dedicated tracks fill the image-bearing area of each frame. The film has only a single film perforation along one edge for each frame. The camera-dedicated tracks lie along the edges of the film between the film perforations. Each track begins and ends within a single frame, and is divided into a plurality of fields.

FILM INFORMATION EXCHANGE SYSTEM USING DEDICATED MAGNETIC TRACKS ON FILM

A virtually transparent magnetic layer (120) is included as an additional layer in a color negative film (100). Information exchange between various users of the film -such as (for example) the film manufacturer, the camera user, the dealer and photofinisher- is carried via plural longitudinal magnetic tracks (20-24) (F0-F29) on the film that begin and end within individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame, for easy access by a particular one of the various users. Each user has the capability to read and/or write information in the corresponding tracks. The photofinisher-dedicated tracks fill each frame but avoid the film perforations, and are therefore the same for all film formats. Camera-dedicated tracks are accommodated using a special film format having only a single film perforation along one edge for each frame. The camera tracks lie outside of each frame along the imperforate film ...

A dispersion consisting essentially of magnetic particles, a dialkylester of phthalic acid which functions as a dispersing medium, and optionally, a dispersing agent is particularly useful as a precursor to a composition suitable for casting onto a cellulose acid ester support film to form a transparent magnetic recording layer for use in photographic films. The dispersion provides magnetic recording layers exhibiting fewer particle agglomerations and reduced light scattering and photographic prints prepared from films containing such magnetic layers exhibit virtually no increase in graininess attributable to the magnetic recording layer.

Film information exchange system using self-clocking encoded start and stop sentinels

A magnetic layer is included as an additional layer in a photographic film. Information exchange between various uses of the film, such as the camera user, the dealer and photofinisher, is facilitated by recording data in dedicated frame-limited longitudinal track(s) in said film. All data is recorded on the film using a self-clocking three-part code in order to provide automatic data synchronization between the various users without requiring film transport at the same speed or even a uniform speed when reading and writing data. Three-part encoded binary characters uniquely representing start and stop sentinels respectively, are recorded at the beginning and end of the track respectively and facilitate automatic detection of the direction of film strip transport.

The cutting tool material includes zirconia and yttria at a molar ratio of yttria to zirconia from about 0.5:99.5 to about 5:95. The cutting tool is essentially a tetragonal crystal phase grain for the interior in a surface of cubic crystal phase grain or monoclinic crystal phase grain. This provides a hard, tough outer surface with a tough core. The cutting tool material can also be a composite of zirconia-alumina with or without surface modification.

Method for the contact-free continuous measurement and monitoring of magnetic tracks on moving film strips

The invention relates to a method of contact-free, almost continuous measurement and monitoring of the width, thickness and position of magnetic tracks on moving film strips within wide limits of the speed. The track width and track position of the magnetic tracks are measured optically and the magnetically acting track cross section is measured electromagnetically via the track volume. The measured values are together recorded, evaluated and displayed and/or used for recontrolling the casting arrangement for emitting warning signals or for stopping the coating machine.

Process for the manufacture of carriers for optical or acoustic purposes

Film carriers for optical or acoustic purposes (e.g. optical or magnetic sound film carriers) are made by applying at least the carrier substance by electrostatic spraying on to a smooth base and stripping it therefrom when dry. The carrier substance (e.g. celluloid or acetyl cellulose) may be applied dissolved in a highboiling solvent, excess of solvent being preferred, so as to produce a uniform surface of great smoothness. A metal strip may be used in known manner as base, electrically-charged for the spray process. The material to be applied by spraying may be electrostatically charged, e.g. by means of known spray electrodes, before spraying, and the material which is to be coated by subjection to spraying may be passed over a flat electrode or laid on such an electrode and sprayed. Spraying may be carried out continuously. Details are given of the application of the process to the preparation of materials for use in colour photography. (see Group XX).

Recording of images

This invention describes a process for improvements in security for personal identification documents, particularly for machine-readable passports. An image of a personal identifier of a holder of the document is stored as a highly-compressed digital image in a magnetic medium dispersed invisibly within the material of a visible print forming part of the document or within the body of the document itself. The document is then scanned magnetically at the place where identification is required and the stored image decompressed and displayed. This provides confirmation that the holder of the document is the person shown on the visible image, that the document has not been tampered with, and by checking the image code against a database, that the document was originated by the proper authority.

Photofinishing apparatus with film information exchange system using dedicated magnetic tracks on film

PHOTOFINISHING APPARATUS WITH FILM INFORMATION EXCHANGE SYSTEM USING DEDICATED MAGNETIC TRACKS ON FILM ABSTRACT A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film--such as (for example) the film manufacturer, the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film that begin and end within each individual frame. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame. The photofinisher-dedicated tracks fill the image-bearing area of each frame. The film has only a single film perforation along one edge for each frame. The camera-dedicated tracks lie along the edges of the film between the film perforations. Each track begins and ends within a single frame, and is divided into a plurality of fields. The spatial relationship between the start location of the tracks associated with each film frame and the corresponding perforation determines the spatial relationship between the magnetic heads and the perforation sensor in the photofinishing apparatus.
