Abstract: A compact padding machine for screening and conveying soil into a trench. The machine is usable as an attachment to a conventional bucket loader, bulldozer or other base machine. The padding machine includes a screening belt, an underlying inclined conveyor belt, and a transverse, extendible discharge conveyor belt. Soil is collected and conveyed upwardly on the screening belt. Fine grained soil passes through the screening belt, is deposited onto the inclined conveyor belt, and is discharged therefrom onto the transverse conveyor belt, from where it may be conveyed into an adjacent trench. A hydraulic vibrator is coupled to the screening belt to disaggregate clods of fine-grained soil and cause the soil to pass through the screening belt. Rocks and other large objects are conveyed to the rear of the machine and discharged.

Abstract: A process for treating metal surfaces to obtain improved susceptibility to bonding with adhesive compositions is disclosed. A metal surface is oxidized with a halogen to form a monolayer of halide ions on the surface. The halide ions are then exchanged with azide ions to form an azide monolayer on the metal surface. Upon contact of the treated surface with an adhesive composition, the azide layer may be thermally or photochemically decomposed to form active nitrene species, which react to bond the adhesive composition to the metal surface.
