Abstract

1445097 Badge or label PLESSEY CO Ltd 30 Oct 1973 [4 Nov 1972] 50917/72 Heading G4M A label, e.g. for luggage or an identifying badge contains a substrate carrying a plurality of light reflective or fluorescent spots or bars arranged in three similar lines connected to each other and at a non-zero angle to each other such that one line can be read independently of the other two. Preferably the lines radiate from a common point at angles of 120 degrees to each other. The spots may be glass beads and may be arranged in an error correcting code.
