Abstract

Abstract A package comprising a light-proof envelope or bag containing a plurality of X-ray film sheets stacked for co-operation with a dispensing machine and useful in a daylight handling system for daylight loading and unloading of cassettes. The film sheets are identical and may have a photographic emulsion layer on one or both surfaces. The adjacent films in the stack have their surfaces in contact. Each sheet has a cut-away portion along one edge thereof for coacting with a film selector cam. In the stack, the sheets are alternated so that the cut-away portions lie along a common stack edge and are arranged in two parallel rows. The cut-away portions in adjacent sheets are in different rows and in superposition. After the package is in a dispenser, the envelope or bag is stripped from the stack so that the sheets can be removed one at a time from the stack and passed into film holders or cassettes engaged with the dispensing machine.

Claim 1
Independent Claim 67 words
A film package for use in a daylight handling system, said package comprising a. a plurality of substantially identical photographically sensitive film sheets, each sheet having a cut-away portion of small area along an edge thereof, said sheets being stacked in alternating superposition whereby the cut-away portions of alternate sheets form discontinuous, spaced apart, parallel rows; and b. cover means opaque to actinic radiation surrounding said stack.
Claim 2
Dependent Claim 67 words
A film package for use in a daylight handling system, said package comprising a. a plurality of substantially identical photographically sensitive film sheets, each sheet having a cut-away portion of small area along an edge thereof, said sheets being stacked in alternating superposition whereby the cut-away portions of alternate sheets form discontinuous, spaced apart, parallel rows; and b. cover means opaque to actinic radiation surrounding said stack.
Claim 3
Dependent Claim 19 words
A package according to claim 1 wherein said rows are spaced apart along a common edge of said stack.
Claim 4
Dependent Claim 24 words
A package according to claim 2 wherein said rows are spaced equidistant from opposite sides of a center line perpendicular to said common edge.
Claim 5
Dependent Claim 13 words
