Manufacturing photographic webs

Claim 2

In a system for imparting latent images of sequential reference indicia along the length of a photographic web, the system including a projection printer past which said web, during manufacture thereof, is transportable, said projection printer having: a. at least one mechanical counter having a drivable input shaft, b. means for flashing the face of said counter, and c. means for projecting said counter face onto said web, the improvement including: a. a pulse-responsive stepping motor so connected to drive said counter input shaft that said counter may index from count to count, and b. controller means operable with both said stepping motor and said means for flashing to pulse first said stepping motor, and then to actuate said flashing means, said controller means comprising: a. a pair of relatively rotatable, but fixedly positionable, members, each of which members supports in spaced apart relationship a lamp aligned with a photocell, b. a disk, having at least one aperture therethrough, said disk being so adapted for rotation that said aperture may align with, and between, the respective lamps and photocells of both said members, c. means for rotating said disk, and d. respective means responsive to the output signals from the said photocells of said members respectively to pulse said stepping motor and to actuate said means for flashing.

Claim 3

The system of claim 1 including means for rotating said disk in proportion to the rate at which said web is transported past said projection printer.

Claim 4

means for flashing the faces of said counters, and

Claim 5

means for flashing the faces of said counters, and

Claim 6

means for so projecting the said counter faces onto the surface of said web that, after said web is slit, the indicia on said counter faces respectively appear on the respective web sections, the improvement comprising: a. respective stepping motors for indexing the said counters, and b. means for pulsing said stepping motors and for thereafter actuating the said means for flashing, said means for pulsing and actuating being adapted to pulse and actuate at a rate proportional to the rate at which said means for transporting conveys said web past said projection printer, and said means for pulsing and actuating comprising: a. a shaft, b. first and second U-shaped members adapted to be relatively fixedly positionable about said shaft, said first U-shaped member supporting in spaced-apart relationship a lamp and a photocell, and said second U-shaped member supporting in spaced apart relationship a lamp and a photocell, c. a disk secured to and drivable by said shaft, said disk having at least one aperture therethrough that, depending on the angular orientation of the disk, allows the lamp of the first U-shaped member to illuminate its corresponding photocell, and the lamp of the second U-shaped member to illuminate its corresponding photocell, d. means responsive to the rate that said web is transported past said projection printer to drive said shaft, and e. means for applying the signal output of said photocell on said first U-shaped member to said stepping motors, and for applying the signal output of said photocell on said second U-shaped member to said means for flashing.

Claim 7

means for so projecting the said counter faces onto the surface of said web that, after said web is slit, the indicia on said counter faces respectively appear on the respective web sections, the improvement comprising: a. respective stepping motors for indexing the said counters, and b. means for pulsing said stepping motors and for thereafter actuating the said means for flashing, said means for pulsing and actuating being adapted to pulse and actuate at a rate proportional to the rate at which said means for transporting conveys said web past said projection printer, and said means for pulsing and actuating comprising: a. a shaft, b. first and second U-shaped members adapted to be relatively fixedly positionable about said shaft, said first U-shaped member supporting in spaced-apart relationship a lamp and a photocell, and said second U-shaped member supporting in spaced apart relationship a lamp and a photocell, c. a disk secured to and drivable by said shaft, said disk having at least one aperture therethrough that, depending on the angular orientation of the disk, allows the lamp of the first U-shaped member to illuminate its corresponding photocell, and the lamp of the second U-shaped member to illuminate its corresponding photocell, d. means responsive to the rate that said web is transported past said projection printer to drive said shaft, and e. means for applying the signal output of said photocell on said first U-shaped member to said stepping motors, and for applying the signal output of said photocell on said second U-shaped member to said means for flashing.

Claim 8

In a system for producing, from a photographic web, at least one pair of narrower photographic web sections, each of which narrower web sections has latent images of sequential reference indicia disposed along its respective length, and which system comprises: a. means for transporting said web in the direction of its length, and means for slitting said web lengthwise into said web sections, b. a projection printer, disposed before said means for slitting in the direction that said web in transportable, said projection printer having:

Claim 9

In a system for producing, from a photographic web, at least one pair of narrower photographic web sections, each of which narrower web sections has latent images of sequential reference indicia disposed along its respective length, and which system comprises: a. means for transporting said web in the direction of its length, and means for slitting said web lengthwise into said web sections, b. a projection printer, disposed before said means for slitting in the direction that said web in transportable, said projection printer having:
