Internally readable identifying tag
First Claim
1. An identifying tag for implanting in small animals including fish to aid in determining the movement thereof from one habitat to another and which is identifiable by means of X-ray equipment, which comprises a solid one piece generally uniformly shaped metallic elongated member being of a length sufficiently small so as to render said member suitable for implantation into an animal, said metallic member having a substantially oblong cross-sectional shape to facilitate orientation of said tag when implanted in said animal and a longitudinal length significantly greater than the maximum cross-sectional width thereof suitable for maintaining sufficient data storage capacity on said tag, said metallic elongated member having cut in its outer surface a plurality of spaced grooves at least some of which extend only partially about the non-circular peripheral surface of said elongated member to form a predetermined fixed format binary coding system which includes an indexing means to define the reading direction of the coded grooves, said grooves being of a sufficient depth such that in profile each of said grooves is readily identifiable as being transparent as distinguished from opaque by means of X-ray equipment while said tag remains implanted in said animal.

Abstract
A metallic identifying tag for allowing later identification of a non-metallic object. The identifying tag is of a circular or oblong cross-section and has a plurality of spaced grooves cut along the surface thereof. In addition, holes may be provided through the center of the tag in conformance with a predetermined pattern which thus forms a profile readily identifiable by means of x-ray equipment. In this manner, while the tag remains implanted within the object it may be inspected and the coded pattern interpreted and the history of the object containing the tag thus ascertained.
