Abstract

Abstract An X-ray film identification device in which one unexposed edge of an X-ray film is placed adjacent a radiation transparent window in which is displayed a set of identifying characters. The identifying characters are located on slidable strips which are guided individually from a remote location into registering position with the window. One end of each of the individual strips is attached to a separate wheel which is rotated to bring various indicia on the strips into registering location with the window.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 216 words
A film identification device comprising: a housing member; an X-ray radiation shield member adjacent said housing member; an unshielded window means in said housing and said shield member; a flexible strip path means extending in said housing member and intersecting said window means; a plurality of independently rotatable wheel elements mounted on said housing member at an accessible location remote from said window means; a plurality of flexible indicia bearing strip means slidably received in said path means and adapted to extend past said window means, individual strip means being independently slidably movable responsive to the rotation of a wheel element to position preselected indicia bearing portions of said strip means adjacent said window means, each of said flexible indicia bearing strip means including two sets of indicia characters, said indicia characters being substantially opaque to X-ray radiation, each of said sets including substantially the same indicia characters, whereby a character from one set of indicia is positioned adjacent the window means and substantially the same character from the second set of indicia is displayed at an accessible location remove from said window means; and means for projecting radiation through said window means and onto an X-ray radiation sensitive film whereby an image of the indicia characters adjacent said window means is recorded on said film.
Claim 2
Dependent Claim 216 words
A film identification device comprising: a housing member; an X-ray radiation shield member adjacent said housing member; an unshielded window means in said housing and said shield member; a flexible strip path means extending in said housing member and intersecting said window means; a plurality of independently rotatable wheel elements mounted on said housing member at an accessible location remote from said window means; a plurality of flexible indicia bearing strip means slidably received in said path means and adapted to extend past said window means, individual strip means being independently slidably movable responsive to the rotation of a wheel element to position preselected indicia bearing portions of said strip means adjacent said window means, each of said flexible indicia bearing strip means including two sets of indicia characters, said indicia characters being substantially opaque to X-ray radiation, each of said sets including substantially the same indicia characters, whereby a character from one set of indicia is positioned adjacent the window means and substantially the same character from the second set of indicia is displayed at an accessible location remove from said window means; and means for projecting radiation through said window means and onto an X-ray radiation sensitive film whereby an image of the indicia characters adjacent said window means is recorded on said film.
Claim 3
Dependent Claim 40 words
A film identification device of claim 1 wherein one end of each of the flexible indicia bearing strip means is attached to a location on the periphery of a wheel element for movement with the periphery of said wheel element.
Claim 4
Dependent Claim 23 words
A film identification device of claim 1 including means for providing time indicating indicia adjacent said window means for recording on said film.
Claim 5
Dependent Claim 38 words
A film identification device of claim 1 including switch means adjacent said window means for actuating said means for projecting radiation responsive to the presence of an X-ray film holder in a predetermined position adjacent said window means.
Claim 6
Dependent Claim 118 words
A film identification device of claim 1 wherein the wheel elements are assembled together into a cylinder mounted on the housing member at a location remote from the window means, the rotation of the individual wheel elements being limited by stop means to an arc of less than about 360*, detent means operatively associated with said wheel elements to releasably hold independently selected wheel elements at predetermined locations along said arcs, a guard member adjacent the cylindrical surface of said cylinder to confine and guide said flexible indicia bearing strip means on the periphery of said wheel elements, and means for providing access to said individual wheel elements to permit an operator to independently rotate said wheel elements.
