Abstract
Abstract The invention relates to a film presenting a series of sound tracks and a series of images. Each sound track is a spiral lodged between two concentric circles and each image is placed inside the smallest circle of a sound track. The invention also refers to an apparatus for the optical recording of such sound tracks and images. It comprises a light modulator, means for effecting the two movements capable of generating a spiral, and recording means. The invention also concerns an apparatus for the optical reading of such sound tracks in spiral. It comprises an optical outfit of which at least one of the elements is subjected to a movement resulting from a movement of rotation and a rectilinear movement.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
An apparatus for optical recording on a film a series of images and a series of sound tracks comprising film-holding means having an opening therein, light-modulating means aligned with the opening of said filmholding means, means for effecting the two movements capable of generating a spiral following any law, of said film-holding means and said light-modulating means relative to each other, and means aligned with said film holding means for optically recording each sound track, which sound track follows a spiral between two concentric circles on the same film with an image, which image is formed inside the smallest circle of said sound track.
Claim 2
Independent Claim
104 words
An apparatus for optical recording on a film a series of images and a series of sound tracks comprising film-holding means having an opening therein, light-modulating means aligned with the opening of said filmholding means, means for effecting the two movements capable of generating a spiral following any law, of said film-holding means and said light-modulating means relative to each other, and means aligned with said film holding means for optically recording each sound track, which sound track follows a spiral between two concentric circles on the same film with an image, which image is formed inside the smallest circle of said sound track.
Claim 3
Dependent Claim
29 words
An apparatus according to claim 1, further including an intermediate optical device connected to said means for effecting the two movements capable of generating a spiral and affected thereby.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 1 wherein: the means effecting one of the movements capable of generating a spiral are applied to said light modulator, the means effecting the other movement being applied to the film.
Claim 5
Dependent Claim
36 words
An apparatus according to claim 3 wherein: means effecting a rotary movement about an axis are applied to a plane portion of the film, means effecting a radial rectilinear movement are applied to said light modulator.
Claim 6
Dependent Claim
32 words
An apparatus according to claim 4 comprising: a light-tight rotary case, an opening made in said case, the said plane portion of the film being maintained in said case behind said opening.
Claim 7
Dependent Claim
26 words
An apparatus according to claim 4 comprising: a pressing device, the said device maintaining the plane portion of the film in a flattened condition during recording.
Claim 8
Dependent Claim
32 words
An apparatus according to claim 6 comprising: a suction means, the said means creating suction between said pressing device and the film so as to increase the flatness of the film portion.
Claim 9
Dependent Claim
35 words
An apparatus according to claim 3 wherein: means effecting radial rectilinear movement are applied to a plane portion of the film, means effecting a rotary movement about an axis are applied to said light modulator.
Claim 10
Dependent Claim
62 words
An apparatus according to claim 8 comprising: a controlling means is provided between said means effecting a radial rectilinear movement and said means effecting a rotary movement about an axis. 10 An apparatus according to claim 9 wherein: the said controlling means is mechanical and includes in particular a cam causing a radial rectilinear movement of said plane portion of the film.
Claim 11
Dependent Claim
39 words
An apparatus according to claim 10 wherein: the profile of said cam is a spiral the vector radius of which varies by an amount corresponding to the pitch of the spiral to be obtained for a given polar angle.
Claim 12
Dependent Claim
30 words
An apparatus according to claim 11 comprising: a clutch device for said cam operatively connected to said cam, and means for starting rotation of said cam from a predetermined positiOn.
Claim 13
Dependent Claim
30 words
An apparatus according to claim 4 comprising: a controlling means is provided between said means effecting a radial rectilinear movement and said means effecting a rotary movement about an axis.
Claim 14
Dependent Claim
28 words
An apparatus according to claim 28 wherein: the said controlling means is mechanical and includes in particular a cam causing a radial rectilinear movement of said light-modulating means.
Claim 15
Dependent Claim
39 words
An apparatus according to claim 14 wherein: the profile of said cam is a spiral the vector radius of which varies by an amount corresponding to the pitch of the spiral to be obtained for a given polar angle.
Claim 16
Dependent Claim
30 words
An apparatus according to claim 30 comprising: a clutch device for said cam operatively connected to said cam, and means for starting rotation of said cam from a predetermined position.
