Abstract
Abstract A photographic filmstrip having predefined image areas regularly spaced from one another at a uniform pitch distance includes discontinuities for facilitating the splicing of two of such filmstrips together end-to-end in such a manner that, when spliced, the endmost image area of one strip will be spaced from the adjacent image area of the other strip by a distance which is a multiple of the pitch distance.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
In a given filmstrip having a leading end, a trailing end, means for defining a plurality of metering perforations longitudinally spaced at uniform intervals along said filmstrip, and a plurality of predefined like image areas residing at regular, longitudinally-spaced locations along said filmstrip so as to define a predetermined pitch distance between adjacent image areas as measured from a point on one of said adjacent image areas to a corresponding point on the other of said adjacent image areas, the improvement wherein: said given filmstrip is further provided with first and second registration means at, respectively, the leading and trailing ends of said given filmstrip, said registration means being so located that when the first registration means of said given filmstrip is placed in register with a second registration means of a like second filmstrip that is longitudinally aligned with said given filmstrip, the distance between a point on the leading image area of said given filmstrip and a corresponding point on the trailing image area of said second filmstrip will be substantially equal to three times said pitch distance.
Claim 2
Dependent Claim
180 words
In a given filmstrip having a leading end, a trailing end, means for defining a plurality of metering perforations longitudinally spaced at uniform intervals along said filmstrip, and a plurality of predefined like image areas residing at regular, longitudinally-spaced locations along said filmstrip so as to define a predetermined pitch distance between adjacent image areas as measured from a point on one of said adjacent image areas to a corresponding point on the other of said adjacent image areas, the improvement wherein: said given filmstrip is further provided with first and second registration means at, respectively, the leading and trailing ends of said given filmstrip, said registration means being so located that when the first registration means of said given filmstrip is placed in register with a second registration means of a like second filmstrip that is longitudinally aligned with said given filmstrip, the distance between a point on the leading image area of said given filmstrip and a corresponding point on the trailing image area of said second filmstrip will be substantially equal to three times said pitch distance.
Claim 3
Dependent Claim
18 words
The invention of claim 1 wherein said first registration means comprises a discontinuity adjacent said leading filmstrip end.
Claim 4
Dependent Claim
18 words
The invention of claim 2, wherein said second registration means comprises a discontinuity adjacent said trailing filmstrip end.
