Apparatus for the marking of X-ray film
First Claim
1. A device for marking X-ray film with identifying characters, the film being held prior to exposure in a cassette of non-X-ray shielding material, said device comprising:
- indicia of X-ray shielding material;
means rigidly secured to said indicia for supporting said indicia;
means for releasably securing said supporting means and therewith said indicia to the cassette; and
a generally flexible tab connected to said supporting means and extending outwardly therefrom for facilitating the removal of said supporting means and therewith said indicia from the cassette.

Abstract
An X-ray film marking device for selectively shielding X-ray film from X-rays so as to imprint identifying characters on the subsequently developed X-ray film. Lead indicia are supported by an X-ray transparent support sheet. The support sheet and therewith the indicia is releasably secured to any suitable structure between the X-ray source and film by a flexible pad having pressure-sensitive coatings of adhesive substances. A tab connected to the support sheet and of a predetermined color for easy association with a particular indicia allows for rapid removal of the marking device.

8. A device for selectively shielding X-rays from X-ray film during exposure so as to imprint identifying indicia on the X-ray film, the device being attachable to X-ray permeable structure between the X-ray source and film, the device comprising:
-
indicia of a relatively thin layer of lead; a generally planar relatively thin support sheet constructed of X-ray permeable material and having an upper surface to which said indicia are bonded and a lower surface; a generally planar relatively thin pad having an upper face coated with an adhesive substance for removably connecting said pad to the lower surface of said sheet, and a lower face coated with an adhesive substance for releasably securing said pad and therewith said sheet and indicia to said X-ray permeable structure; and a generally flexible tab connected to said sheet for facilitating the removal of the device from said X-ray permeable structure. - View Dependent Claims (9, 10, 11, 12, 13)

14. A device for marking X-ray film with identifying characters, the film being held prior to exposure in a cassette of non-X-ray shielding material, said device comprising:
-
indicia of X-ray shielding material; means rigidly secured to said indicia for supporting said indicia; and a relatively thin, generally planar pad releasably secured to said supporting means having a coating of pressure-sensitive adhesive on its lower surface, said pad also having a plurality of holes extending throughout its thickness for providing a partial vacuum between said supporting means and the cassette to thereby enhance the securing of said supporting means and therewith said indicia to the cassette.
