Abstract
Abstract An apparatus and method for recording television scenes onto photographic film in a format suitable for use in conventional optical motion picture projectors. A beam splitter is used to simultaneously record the scanning spots of a TV signal onto two adjacent frames of an intermediate, continuously running film such that two fully interlaced TV fields are recorded on every frame of the intermediate film. Selected frames from the intermediate film are then printed onto conventional photographic motion picture film in a format which can then be used in conventional optical motion picture projectors.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
100 words
An apparatus utilizing a continuously run intermediate recording media for transcribing images representative of television signals onto photographic film in a format suitable for use in conventional motion picture projectors, said apparatus comprising: means for producing interlaced scanning spots in response to said television signals; means for recording said interlaced scanning spots simultaneously onto two adjacent frames of said intermediate media thereby recording two interlaced television fields on every frame of said media; and means for recording selected ones of said frames from said media onto said photographic film in a format suitable for use in conventional motion picture projectors.
Claim 2
Independent Claim
100 words
An apparatus utilizing a continuously run intermediate recording media for transcribing images representative of television signals onto photographic film in a format suitable for use in conventional motion picture projectors, said apparatus comprising: means for producing interlaced scanning spots in response to said television signals; means for recording said interlaced scanning spots simultaneously onto two adjacent frames of said intermediate media thereby recording two interlaced television fields on every frame of said media; and means for recording selected ones of said frames from said media onto said photographic film in a format suitable for use in conventional motion picture projectors.
Claim 3
Dependent Claim
19 words
The invention of claim 1 wherein the intensities of said interlaced scanning spots are modulated by said television signals.
Claim 4
Dependent Claim
26 words
The invention of claim 1 wherein said producing means comprises means for emitting two interlaced scanning spots of equal intensity simultaneously modulated by said television signals.
Claim 5
Dependent Claim
23 words
The invention of claim 1 wherein said means for recording said interlaced scanning spots comprises means for friction driving said intermediate recording media.
Claim 6
Dependent Claim
53 words
The invention of claim 1 wherein said producing means comprises means for originating a television raster modulated in accordance with said television signals and means operatively disposed relative to said originating means for emitting two scanning spots of equal intensity from said raster for simultAneously scanning two adjacent areas on said intermediate film.
Claim 7
Dependent Claim
52 words
The invention of claim 1 wherein said producing means comprises a television raster and two objective lenses disposed so as to focus the raster light into leading and following spots a frame pitch apart on said media such that the scan of the following spot interlaces the scan of the leading spot.
Claim 8
Dependent Claim
95 words
The invention of claim 1 wherein said producing means comprises means for scanning modulated in accordance with said television signals; means operatively disposed relative to said scanning means for emitting two scanning spots of equal intensity from the light of said scanning means, said spots being simultaneously modulated by said television signals, said emitting means comprising an objective lens and beam dividing prism assembly disposed to produce a leading and a following spot on said media a frame pitch apart such that the scan of the following spot interlaces the scan of the leading spot.
Claim 9
Independent Claim
120 words
An apparatus utilizing an intermediate recording film for transcribing images representative of television signals onto photographic film in a format suitable for use in conventional motion picture projectors, said apparatus comprising: means for producing a scanning beam modulated by said television signal; means for continuously moving said intermediate film; means for transforming said scanning beam into two interlaced scanning spots; means synchronized with said intermediate film for directing said two interlaced spots onto said intermediate film to form recorded images representative of said television signal onto adjacent frames thereof; and means for recording, including means for determining frames to be selected, from said intermediate film onto said photographic film in a format suitable for use in conventional motion picture projectors.
Claim 10
Independent Claim
120 words
An apparatus utilizing an intermediate recording film for transcribing images representative of television signals onto photographic film in a format suitable for use in conventional motion picture projectors, said apparatus comprising: means for producing a scanning beam modulated by said television signal; means for continuously moving said intermediate film; means for transforming said scanning beam into two interlaced scanning spots; means synchronized with said intermediate film for directing said two interlaced spots onto said intermediate film to form recorded images representative of said television signal onto adjacent frames thereof; and means for recording, including means for determining frames to be selected, from said intermediate film onto said photographic film in a format suitable for use in conventional motion picture projectors.
Claim 11
Independent Claim
129 words
A method of transcribing conventional television signals onto photographic film in a format suitable for use in conventional optical motion picture projectors, utilizing a frame formatted continuously run intermediate film, the method comprising the steps of: producing a scanning beam modulated by the television signals; splitting the scanning beam into two interlaced scanning spots of equal intensity and spaced to simultaneously record interlaced fields onto adjacent frames of the intermediate continuously run intermediate film; scanning the intermediate film with the interlaced scanning spots to record them thereon in frame format; determining which frames are to be selected for transferring; and transferring the images recorded on selected ones of the frames of the intermediate film onto photographic film in a format suitable for use in conventional optical motion picture projectors.
Claim 12
