Abstract: A method for lapping of gun barrels on fully assembied firearms is provided using cartridges fitted with lapping bullets impregnated with abrasive. The present invention provides a process for simultaneously impregnating a quantity of lapping bullets with an abrasive, in which a quantity of unlubricated bullets are placed in a tumbler with steel balls and quantity of the desired abrasive. The speed of rotation of the tumbler, and the shape of the tumbler are selected so that the bullet/abrasive/tumbling media mix folds on itself, thus providing an even impregnation of abrasive on the bullets and minimizing any deformation of the bullets. The mixture is allowed to tumble for a period of time, typically about an hour, after which a sufficient quantity of the abrasive is firmly embedded on the surface of each bullet. The abrasive impregnated bullets can then be coated with a protective and lubricating finish, such as carnauba wax, if desired.

Abstract: Avoidance of the corrosion initiation sites consisting of Mn particles deposited on the TiG welded inner tube surface is achieved through suppression of emission of manganese fumes by addition of a protective non corrosive metallic layer. The latter melts during the welding and arises in a non-corrosive internal metallic coating of the welded zone.

Abstract: A method of converting a toxic composition containing an aldehyde to a composition which is substantially non-toxic. The aldehyde is reacted with a polymer having protic oxygen or nitrogen atoms, a polyimine or polyimine derivative, and an active aromatic to couple or react with the aldehyde-containing composition. Preferably, this aldehyde conversion process will yield a substantially fluid reaction product by way of a substantially irreversible reaction.
