Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
An identification structure for an object to be identified comprising identification means for permitting identification comprising identifying symbols, said identification means made of a first material having a higher melting point than the material of the object to be identified with said first material having a substantially different radiation absorption coefficient, said identification means being surrounded by the material of the object to be identified with said symbols being defined by said first material and the material of the object whereby said symbols can be detected by radiographic techniques, and with said identification means comprising a tag member with said symbols constructed of said first material and a body member retaining said symbols, said body member being constructed of a second material which vaporizes at the melting point of the material of the object whereby said body member is not present as a part of said identification means after the object is formed.
Claim 2
Dependent Claim
153 words
An identification structure for an object to be identified comprising identification means for permitting identification comprising identifying symbols, said identification means made of a first material having a higher melting point than the material of the object to be identified with said first material having a substantially different radiation absorption coefficient, said identification means being surrounded by the material of the object to be identified with said symbols being defined by said first material and the material of the object whereby said symbols can be detected by radiographic techniques, and with said identification means comprising a tag member with said symbols constructed of said first material and a body member retaining said symbols, said body member being constructed of a second material which vaporizes at the melting point of the material of the object whereby said body member is not present as a part of said identification means after the object is formed.
Claim 3
Dependent Claim
27 words
The structure of claim 1 with said first material being a metal and with said material of said object being a metal cast about said identification means.
Claim 4
Dependent Claim
29 words
The structure of claim 2 with said object to be identified being a substantially permanent part of a vehicle whereby a substantially permanent identification of the vehicle is provided.
Claim 5
Dependent Claim
12 words
