SUPPLEMENTAL SECTIONS FOR MOTION-PICTURE FILMS Filed Feb. 1, 1962 in in 00000000 0 \oocooooooooo a spaaas,
o Q gooooooo 0Q iQo \ooooooooo Wolfgang SCHULER mvwron United States Patent 3,179,952 SUPPLEMENTAL SECTIONS FOR MOTION- PICTURE FILMS Wolfgang Schiller, Kurfurstenstrasse 5, Essen (Ruhr), Germany Filed Feb. 1, 1962, Ser. No. 170,400 9 Claims. (Cl. 352--240) My present invention relates to supplemental sections for motionpicture films, particularly for amateur projection, adapted to provide titles, written commentary or special effects such as fade-in or fade-out at the beginning or the end of a scene. This includes, for example, the so-called Hollywood effects whereby, in the transition from one scene to another, increasing or decreasing circles, vortices, undulations or the like are displayed.
Known devices of this character utilize printed strips which are pasted over the exposed and developed film at the locations where the desired effects are to appear. Conventional printing processes, however, render it difficult to provide a full scale of shades ranging from maximum transparency to substantially complete opacity. Inconveniences have also been experienced in fastening these known strips to the basic film.
The principal object of my present invention is to provide an improved supplemental section of this character in which the aforementioned drawbacks are avoided.
Another object of the invention is to provide a film section of this type which can be partly superimposed upon the basic film and partly spliced in between portions thereof.
These objects are realized, in accordance with the present invention, by the provision of a transparent strip of the usual film material, e.g. cellulose acetate or nitrocellulose, that carries on one side a developed photosensitive emulsion on which the desired inscriptions, patterns or the like have been photographically recorded and which also has an adhesive surface coating whereby it may be bonded to the principal film in proper alignment therewith.
In a preferred embodiment I provide a separate carrier strip with two adhesive surfaces which is bonded to the first-mentioned film strip, i.e. the emulsion support, to form the adhesive coating; the exposed side of the carrier strip is advantageously covered by a protective strip which can be pulled off when the device is to be secured to the basic film. All the strips referred to, including the protective strip and the adhesive materials carried thereon, should be sufficiently transparent to enable ready visual ascertainment of the picture content of the developed emulsion and to permit unhindered translumination of the film to which the device is applied.
I have found that the usual adhesives adapted to be used with cellul-osic film material bond more firmly to the photographic emulsion than to the bare film, the removal of the protective strip being thus accomplished without risk of detaching the adhesive carrier from the emulsion support if the carrier overlies the emulsion side of this support.
Thus, the three strips used in the preferred construction of a supplemental film section according to this invention may all consist of the same film material which in turn may be identical with that of the principal film to which the device is subsequently applied. The adhesives may be of either the tacky or the pressure-sensitive type and may include, for example, neoprene-base rubber segments or vinyl-acetate compounds.
Where the device of my invention is to be used as a splice-in section, it should be provided with lateral sprocket perforations which may also extend over the adhesivecoated portions to register with the corresponding perforations of the basic film portions to be bonded thereto. Moreover, it is contemplated that a plurality of diverse sections be combined side-by-side into an assembly from which they may be individually detached.
My invention will be described in greater detail with reference to the accompanying drawing in which:
FIG. 1 is a plan view of an assembly of supplemental film sections embodying the invention;
FIG. 2 is a fragmentary cross-sectional veiw taken on the line IIII of FIG. 1; and
FIG. 3 is a view similar to FIG. 1, showing a modified device adapted to be used as a splice-in section.
The device 10 shown in FIGS. 1 and 2 consists of a plurality of parallel sections each including a respective supporting strip 1 with a developed emulsion generally designated 2 in FIG. 2; different patterns 2a, 2b, 2c, 2d, 22, 2 are shown photographically recorded on the several emulsions. The composite 1, 2 is overlain by a transparent carrier strip 3 which is bonded to the emulsion 2 by an adhesive layer 3'. Another, similar layer 3" on the opposite side of strip 3 is temporarily covered by a removable protective strip 4; each of these sections bearing patterns 2a, 2b, etc. is adapted to be severed from the others and will then have a width corresponding to that of a conventional amateur motion-picture film exclusive of its perforated side or sides. Upon the detachment of the corresponding protective strip 4 the remainder of the section is ready to be placed upon the basic film, not shown, and bonded to it by means of the adhesive layer 3". The combination of strips and coatings 3', 3 and 4 has been designated by the numeral 5 in FIG. 2.
The section 20 illustrated in FIG. 3 is generally similar in its composition to each of the sections of FIGS. 1 and 2, the difference being that the adhesive composites 5 and 5" extend only over the terminal portions of the emulsion-coated support 1'. It will be noted that this support and its coatings 5', 5" have been provided with lateral sprocket perforations 6 to register with the corresponding perforations of the basic film, not shown, which can be cut into two portions respectively terminating at the boundaries 7', 7" of coatings 5 and 5". Thus, the legend Vacation 1961 appearing on the strip illustrated in FIG. 3 may be displayed between two scenes to be successively projected. Either one or two rows of perforations 6 will be required, depending on the type of film used.
The photographic recording of the patterns and titles of FIGS. 1 and 3 on the photosensitive layers can be effected with conventional equipment that does not require any further description.
