Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
132 words
AN X-RAY FILM PACKAGE FOR APPLYING DIMENSION INDICIA ON THE DEVELOPED X-RAY FILM, COMPRISING: A SEALABLE, LIGHT EXCLUDING, THIN ENVELOPE, HAVING A POCKET DEFINED THEREIN AND HAVING A FIRST SURFACE; AND X-RAY FILM HAVING A FIST SURFACE WHICH IS TO BE EXPOSED TO X-RADIATION; SAID FILM BEING POSITIONED IN SAID ENVELOPE POCKET AND SAID FILM FIRST SURFACE FACING SAID FIRST SURFACE OF SAID ENVELOPE; SAID ENVELOPE FIRST SURFACE BEING COMX-RADIATION TRANSPARENT MATERIAL; X-RADIATION OPAQUE MATERIAL ARRANGED TO DEFINED DIMENSION INDICIA AND SUPPORTED IN POSITION NEAR SAID FILM FIRST SURFACE AND ON THE SIDE OF SAID FIRST FILM SURFACE THAT FACES TOWARD AN X-RAY SOURCE; WHEREBY EXPOSURE OF SAID X-RAY FILM PACKAGE TO X-RADIATION IMPINGED UPON SAID ENVELOPE FIRST SURFACE PRODUCES A PHOTOGRAPHIC IMAGE OF THE DIMENSION INDICIA ON SAID FILM FIRST SURFACE.
Claim 2
Dependent Claim
132 words
AN X-RAY FILM PACKAGE FOR APPLYING DIMENSION INDICIA ON THE DEVELOPED X-RAY FILM, COMPRISING: A SEALABLE, LIGHT EXCLUDING, THIN ENVELOPE, HAVING A POCKET DEFINED THEREIN AND HAVING A FIRST SURFACE; AND X-RAY FILM HAVING A FIST SURFACE WHICH IS TO BE EXPOSED TO X-RADIATION; SAID FILM BEING POSITIONED IN SAID ENVELOPE POCKET AND SAID FILM FIRST SURFACE FACING SAID FIRST SURFACE OF SAID ENVELOPE; SAID ENVELOPE FIRST SURFACE BEING COMX-RADIATION TRANSPARENT MATERIAL; X-RADIATION OPAQUE MATERIAL ARRANGED TO DEFINED DIMENSION INDICIA AND SUPPORTED IN POSITION NEAR SAID FILM FIRST SURFACE AND ON THE SIDE OF SAID FIRST FILM SURFACE THAT FACES TOWARD AN X-RAY SOURCE; WHEREBY EXPOSURE OF SAID X-RAY FILM PACKAGE TO X-RADIATION IMPINGED UPON SAID ENVELOPE FIRST SURFACE PRODUCES A PHOTOGRAPHIC IMAGE OF THE DIMENSION INDICIA ON SAID FILM FIRST SURFACE.
Claim 3
Dependent Claim
17 words
The X-ray film package of claim 1, wherein said X-radiation opaque material is positioned in said envelope.
Claim 4
Dependent Claim
35 words
The X-ray film package of claim 2, wherein said radiation opaque material comprises filaments of X-radiation transparent material which carry particles of X-radiation opaque material in predetermined concentration with respect to said radiation transparent material.
Claim 5
Dependent Claim
33 words
The X-ray film package of claim 2, wherein said radiation opaque material comprises fine metal wires; said wires being carried by a carrier arranged such that said wires are adjacent said film surface.
Claim 6
Dependent Claim
55 words
The X-ray film package of claim 1, wherein said indicia are in the form of a grid of lines spaced apart predetermined distances; said grid being designed to provide an area therein which is clear of said indicia, thereby to cause an area clear of dimension indicia to appear in the image of said film.
Claim 7
Dependent Claim
40 words
The X-ray film package of claim 1, wherein said radiation opaque material comprises an ink which is comprised of a suspension of particles of X-radiation opaque material in a carrier; said ink being carried on a means inside said envelope.
Claim 8
Dependent Claim
23 words
The X-ray film package of claim 6, wherein said indicia are in the form of a grid of lines spaced apart predetermined distances.
Claim 9
Dependent Claim
18 words
The X-ray film package of claim 6, wherein said inked indicia are applied to said film first surface.
Claim 10
Dependent Claim
40 words
The X-ray film package of claim 8, wherein said ink is soluble in a liquid that is used during a photographic film developing process, thereby to enable the ink to be dissolved off said film during the film developing process.
Claim 11
Dependent Claim
51 words
The X-ray film package of claim 6, wherein the concentration of said X-radiation opaque particles in said ink is preselected to provide predetermined opacity for the image of said indicia on said film as compared with the opacity of the image of the object being X-ray photographed appearing on said film.
Claim 12
Dependent Claim
25 words
The X-ray film package of claim 10, wherein said indicia are in the form of a grid of lines which are spaced apart predetermined distances.
Claim 13
Dependent Claim
17 words
The X-ray film package of claim 6, wherein said X-radiation opaque material is positioned in said envelope.
Claim 14
Dependent Claim
26 words
The X-ray film package of claim 12, further comprising a separate surface near said film first surface; said linked indicia being applied to said separate surface.
Claim 15
Dependent Claim
25 words
The X-ray film package of claim 13, wherein said separate surface carrying said inked indicia is positioned adjacent and opposed to said film first surface.
Claim 16
Dependent Claim
20 words
The X-ray film package of claim 6, wherein said X-radiation opaque material is applied to and supported on said envelope.
Claim 17
Dependent Claim
19 words
The X-ray film package of claim 15, wherein said X-radiation opaque material is applied to said envelope first surface.
Claim 18
Dependent Claim
32 words
The X-ray film package of claim 6, wherein there is an indicia producing means carrying surface within said envelope and said X-radiation opaque material is applied to said surface in said envelope.
Claim 19
Dependent Claim
36 words
The X-ray film package of claim 17, wherein said indicia producing means carrying surface in said envelope is on a protective sheet placed in said envelope between said envelope first surface and said film first surface.
