Abstract

Abstract A principal embodiment of the invention disclosed herein is a process for producing photographic slides which, as a consequence thereof, can be separately projected onto a screen in an overlapping manner with images common to both slides in precise registry. The process consists of preparing artwork, such as graphs, diagrams, charts and the like on a specially prepared format and photographing the work. The resulting film is then critically positioned in a device according to markings therein which correspond with markings on the format. The device known as a registration device constitutes another embodiment of the invention. The film is then punched and trimmed in the device, and thereafter mounted on a mask according to its markings whereupon the thusly mounted film is inserted in the usual carrier employed in slide projectors. The device, which is hereinafter designated a registration device, is deemed part of the invention. Alternatively, the invention comprehends slide carriers of unique construction in which the film that has been punched and scored for trimming in the registration device according to the process may be directly inserted into the carriers, the construction thereof being such that the step in the process of mounting the film onto a mask is eliminated.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 118 words
In a process for producing a photographic slide for projection including the steps of manually producing an artwork on a format having art area delimiting markings and a set of registration marks, producing a reproduction of said format, photographing said reproduction to make a transparency therefrom, placing said transparency on a registration device having a base displaying a corresponding set of registration marks, positioning the film on said base according to said registration marks on the film and said device, producing by said device registry designations on said film, trimming the film to the desired size, disposing said trimmed film on a frame support having corresponding registry designations and positioning the film thereon according to said registry designations.
Claim 2
Dependent Claim 118 words
In a process for producing a photographic slide for projection including the steps of manually producing an artwork on a format having art area delimiting markings and a set of registration marks, producing a reproduction of said format, photographing said reproduction to make a transparency therefrom, placing said transparency on a registration device having a base displaying a corresponding set of registration marks, positioning the film on said base according to said registration marks on the film and said device, producing by said device registry designations on said film, trimming the film to the desired size, disposing said trimmed film on a frame support having corresponding registry designations and positioning the film thereon according to said registry designations.
Claim 3
Dependent Claim 125 words
A process for producing a photographic slide for projection including the steps of manually producing an artwork on a format having art area delimiting markings and a set of registration marks, producing a negative reproduction of said format, photographing said reproduction to make a positive transparency therefrom, placing said transparency on a registration device having a base displaying a corresponding set of registration marks, positioning the film on said base according to said registration marks on the film and said device, producing registry designations on said film using said device, scoring said film on the device and thereafter trimming the film, mounting said film on a mask according to the registry designations thereon, and inverting the mounted film in a film carrier for projection purposes.
Claim 4
Dependent Claim 125 words
A process for producing a photographic slide for projection including the steps of manually producing an artwork on a format having art area delimiting markings and a set of registration marks, producing a negative reproduction of said format, photographing said reproduction to make a positive transparency therefrom, placing said transparency on a registration device having a base displaying a corresponding set of registration marks, positioning the film on said base according to said registration marks on the film and said device, producing registry designations on said film using said device, scoring said film on the device and thereafter trimming the film, mounting said film on a mask according to the registry designations thereon, and inverting the mounted film in a film carrier for projection purposes.
Claim 5
Dependent Claim 55 words
A slide-mounting registration device comprising a base, a reticle glass retained by said base, and adapted to receive a photographic film, registration marks inscribed in said glass for positioning said film, a frame plate adapted to be moved relative to said base and means associated with said device for producing registry designations on said film.
Claim 6
Dependent Claim 55 words
A slide-mounting registration device comprising a base, a reticle glass retained by said base, and adapted to receive a photographic film, registration marks inscribed in said glass for positioning said film, a frame plate adapted to be moved relative to said base and means associated with said device for producing registry designations on said film.
