Abstract
Abstract Motion-picture apparatus for exposing a motion-picture film especially adapted to a diffusion transfer method of image formation; for rapidly processing the exposed film; and for immediately thereafter projecting the film in the form of a finished motion-picture sequence. The system includes, for an improved operation, a unique multi-purpose cassette or magazine usable both in a camera component for the taking function and in a projection component for processing and projection purposes. The camera component of the system, adapted to use the aforesaid motion-picture film and cassette, may, appropriately, be of a type also capable of accepting a standard motion-picture film such, for example, as one having the physical characteristics of a so-called ''''Super-8'''' film, sold by Eastman Kodak Co., Rochester, New York, U.S.A. The camera may, therefore, be of a substantially conventional type with the qualification that it need be adapted to mount the cassette of the invention and optically suited to utilize the film contained therein. The projection or viewing component of the system may, suitably, be in the form of a compact cabinet-type unit incorporating a viewing screen comparable in area to that of a television receiver. Such a unit is primarily intended as a home entertainment device but, alternatively, its use may be extended to scientific or other fields where an immediate showing is of advantage following the taking of a motion-picture. The viewing component may also be used for accommodating standard motionpicture film.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
226 words
A cassette comprising: an enclosed opaque housing configured to be first mounted in a camera to facilitate film exposure operations and subsequently in a projector to facilitate film processing and viewing operations; an unexposed strip of photographic material coiled within said housing; a film gate for access of light rays to selected incremental portions of said strip of material; first means responsive to drive means of such camera when said cassette is mounted therein for progressively advancing said unexposed strip of photographic material past said film gate while retaining said strip of photographic material entirely within said cassette to facilitate the recording of images thereon; a normally inoperative processing station adapted to being selectively rendered operable to apply processing fluid to said strip of material after exposure of said strip of material to image carrying light rays incident through said film gate; second means responsive to drive means of such projector when said cassette is mounted therein after exposure of said strip of photographic material for progressively advancing said strip of material through said processing station while retaining said strip of photographic material entirely within said cassette to facilitate the formation of visible images from said recorded images; and means for selectively rendering said processing station operable when said strip of material in an exposed condition is transported through said processing station by said second means.
Claim 2
Dependent Claim
226 words
A cassette comprising: an enclosed opaque housing configured to be first mounted in a camera to facilitate film exposure operations and subsequently in a projector to facilitate film processing and viewing operations; an unexposed strip of photographic material coiled within said housing; a film gate for access of light rays to selected incremental portions of said strip of material; first means responsive to drive means of such camera when said cassette is mounted therein for progressively advancing said unexposed strip of photographic material past said film gate while retaining said strip of photographic material entirely within said cassette to facilitate the recording of images thereon; a normally inoperative processing station adapted to being selectively rendered operable to apply processing fluid to said strip of material after exposure of said strip of material to image carrying light rays incident through said film gate; second means responsive to drive means of such projector when said cassette is mounted therein after exposure of said strip of photographic material for progressively advancing said strip of material through said processing station while retaining said strip of photographic material entirely within said cassette to facilitate the formation of visible images from said recorded images; and means for selectively rendering said processing station operable when said strip of material in an exposed condition is transported through said processing station by said second means.
Claim 3
Dependent Claim
38 words
The cassette of claim 1 additionally comprising a drying station within said cassette adapted to facilitate the removal of evaporable constituents of said processing fluid therefrom after the application of said fluid to said strip of photographic material.
Claim 4
Dependent Claim
86 words
A cassette supplied loaded with motion-picture film and adapted to rapid mounting in and removal from both a camera and projector comprising a housing having a film gate provided therein, spool means responsive to selective engagement with drive means of sad camera and projector to transport said film across said film gate, film processing means mounted within said housing; and means for selectively bringing said film processing means into operative relationship with said film as it is transported across said film gate by said spool means.
Claim 5
Dependent Claim
86 words
A cassette supplied loaded with motion-picture film and adapted to rapid mounting in and removal from both a camera and projector comprising a housing having a film gate provided therein, spool means responsive to selective engagement with drive means of sad camera and projector to transport said film across said film gate, film processing means mounted within said housing; and means for selectively bringing said film processing means into operative relationship with said film as it is transported across said film gate by said spool means.
Claim 6
Dependent Claim
31 words
The cassette of claim 3 wherein said spool means are responsive to selective engagement with drive means of said camera and projector to reversibly transport said film across said film gate.
Claim 7
Dependent Claim
63 words
The cassette of claim 3 wherein a processing medium in a liquid state is applied to said film when said film processing means is brought into operative relationship with said film and additionally comprising a drying station within said cassette adapted to facilitate the removal of evaporable constituents of said processing medium therefrom after the application of said processing medium to said film.
Claim 8
Dependent Claim
122 words
A cassette supplied loaded with motion-picture film and adapted to rapid mounting in and removal from both a camera and projector comprising: a housing having a film gate provided therein; normally inoperative means for processing said film with a processing medium in a liquid state after exposure thereof mounted within said housing; spool means responsive to selective engagement with drive means of said camera and projector to transport said film across said film gate and said processing means; means for selectively rendering said processing means operable as said film is transported thereacross; and a drying station within said cassette adapted to facilitate the removal of evaporable constituents of said processing medium therefrom after the application of said processing medium to said film.
Claim 9
Dependent Claim
122 words
A cassette supplied loaded with motion-picture film and adapted to rapid mounting in and removal from both a camera and projector comprising: a housing having a film gate provided therein; normally inoperative means for processing said film with a processing medium in a liquid state after exposure thereof mounted within said housing; spool means responsive to selective engagement with drive means of said camera and projector to transport said film across said film gate and said processing means; means for selectively rendering said processing means operable as said film is transported thereacross; and a drying station within said cassette adapted to facilitate the removal of evaporable constituents of said processing medium therefrom after the application of said processing medium to said film.
