Abstract: An apparatus to collect metal particles as generated (galling) by a fastener connection to a workpiece, the fastener having a head and an axially forwardly extending shank, the combination comprising an O-ring about the head; the head forming an outwardly open annular recess spaced from the shank to receive the bulk of the O-ring; the O-ring projecting from the recess to engage the workpiece and form with the head a recess portion to receive and retain the particles.

Abstract: An identification system for individuals which provides a three point identification check at point-of-transaction to assure accuracy is disclosed. The system utilizes an individual fingerprint and an identifier which can be correlated to the fingerprint and to a listing of valid identifiers. In carrying out the system, an identification card is used which has the individual's fingerprint, a grid superimposed over the fingerprint, and an identifier printed thereon. The identifier is made-up of a series of individual designations or symbols, with each individual designation representing a selected fingerprint characteristic in respective squares of the grid. A data bank for individuals in the system contains a listing of valid identifiers for correlation and validation purposes. The identifier may be made up of alpha, numeric, or alpha numeric designations.
