Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
In or for a photocomposing machine, output means for moving a flexible photosensitive record medium past an exposure station at which images are projected onto said medium, said output means comprising a hollow drum with holes in its walls, means for dividing the hollow interior of said drum into sections, drive means for rotating said drum, and holding means for partially evacuating at least one selected section of said drum to hold said medium onto the surface of said drum.
Claim 2
Dependent Claim
80 words
In or for a photocomposing machine, output means for moving a flexible photosensitive record medium past an exposure station at which images are projected onto said medium, said output means comprising a hollow drum with holes in its walls, means for dividing the hollow interior of said drum into sections, drive means for rotating said drum, and holding means for partially evacuating at least one selected section of said drum to hold said medium onto the surface of said drum.
Claim 3
Dependent Claim
43 words
A device as in claim 1, said holding means including means for dividing the hollow interior of said drum into a plurality of separate sections, said holding means being adapted to partially evacuate only the sections around which said record medium is wrapped.
Claim 4
Dependent Claim
44 words
A device as in claim 1 in which said record medium is in roll form, said medium being wrapped more than one-fourth of the distance around said drum, a supply cassette for dispensing said medium, and a take-up cassette for receiving the exposed medium.
Claim 5
Dependent Claim
67 words
A device as in claim 1 in which said record medium is in sheet form, said holding means including means for dividing the hollow interior of said drum into a plurality of separate sections, said holding means being adapted to partially evacuate only the sections around which said record medium is wrapped, and a gas-impervious cover over the portion of said drum not covered by said sheet.
Claim 6
Dependent Claim
34 words
A device as in claim 4 including a selectively actuatable deflector device for selectively moving to a position closely adjacent said drum surface so as to deflect and remove said sheet from said drum.
Claim 7
Dependent Claim
54 words
A device as in claim 1 in which said record medium is capable of being printed on by electrophotographic means, and including corona charging means for charging said medium before reaching said exposure station, and developing means for receiving the exposed medium and applying toner thereto to develop the latent images on said medium.
Claim 8
Dependent Claim
53 words
A device as in claim 6 in which said medium is in discrete sheet form, means for rotating said drum past said corona charging means continuously in one pass to charge said sheet, and leading means for rotating said drum in discrete steps to space lines of characters from one another during composition.
Claim 9
Dependent Claim
70 words
In a photocomposing method, the steps of utilizing a hollow drum to hold a photosensitive medium during the photographic exposure of said medium, separating the hollow interior of said drum into chambers whose locations are stationary, partially evacuating selected ones of said chambers so as to hold said medium on said drum while not evacuating the ones of said chambers which are not at least partially covered by said medium.
Claim 10
Dependent Claim
70 words
In a photocomposing method, the steps of utilizing a hollow drum to hold a photosensitive medium during the photographic exposure of said medium, separating the hollow interior of said drum into chambers whose locations are stationary, partially evacuating selected ones of said chambers so as to hold said medium on said drum while not evacuating the ones of said chambers which are not at least partially covered by said medium.
Claim 11
Dependent Claim
92 words
A photocomposing method utilizing electrophotography, said method comprising moving a first sheet record medium past a corona charging, device to completely charge said medium, simultaneously adhering said sheet to a rotary drum, moving said medium past an exposure station in discrete steps to allow the forming of lines of characters between steps, gradually removing said sheet from said drum to clear successive areas of the surface of said drum and simultaneously charging and gradually adhering a second sheet onto said cleared areas and developing the latent electrostatic images on said first sheet.
Claim 12
Dependent Claim
92 words
A photocomposing method utilizing electrophotography, said method comprising moving a first sheet record medium past a corona charging, device to completely charge said medium, simultaneously adhering said sheet to a rotary drum, moving said medium past an exposure station in discrete steps to allow the forming of lines of characters between steps, gradually removing said sheet from said drum to clear successive areas of the surface of said drum and simultaneously charging and gradually adhering a second sheet onto said cleared areas and developing the latent electrostatic images on said first sheet.
