Abstract: A system for identifying an object including a conveyer mechanism, a diverting bar, a counterweight, an object collector, an object inspector, and a selection arm. The diverting bar includes a body which may be positioned at least partially over the conveyer mechanism as to divert one or more objects of a plurality of objects traveling on the conveyer mechanism. The counterweight is coupled to the diverting bar and applies a biasing force against the one or more objects as to reduce the force applied to the plurality of objects. The object collector may be positioned adjacent the conveyer mechanism and is configured to accept an object from the conveyer mechanism and inspect the object for at least one marking. Once inspected, the selection arm is configured to deliver the object to a target position or back to the conveyer mechanism based on at least one marking.

Abstract: A method of manufacturing an interference coating on the surface of an aluminum alloy or aluminum alloys product comprising anodizing and electrochemical dyeing with use of alternating current consisting in that, the electrolyte used during electrochemical dyeing comprises copper (II) sulfate (IV) in an amount from 1 to 100 g/L, boric acid in the amount of 1 to 40 g/L and tartaric acid in the amount of 0.1 to 20 g/L.
