Abstract: A conveyor system for handling containers, particularly non-rigid bottles or jars, wherein the containers are gripped firmly but resiliently, to minimize deformation, and are conveyed, without friction or danger of marring, to a delivery zone where they can be delivered individually or in groups. The container gripping means includes holding jaws carried by complementary endless belts or chains, and inflatable pressure adjusting air bags for urging the holding jaws into engagement with the containers, holding them precisely spaced for subsequent operations and releasing them accurately on signal.

Abstract: Apparatus including means for fluidically supporting and guiding a moving, cylindrically formed thin metal belt used in the transport of magnetic particles. Magnet pole pieces disposed adjacent the surface of the belt accommodate formation thereon of a non-translating, rotating bead of dry magnetic ink particles in the application of a uniform ink coating over the belt suitable for printing. The belt is held in substantially fluid tight relation along its opposed edges on bearing means affording rotation of the belt about a fixed, axially extending mandrel including fluid supply cavities and a magnet support cavity. The fluid supply cavities terminate in radially presented recessed orifices for discharging a fluid into a relatively close space provided between the mandrel and the belt, to the side of the latter opposite the surface on which the ink bead is formed by a magnet disposed within the magnet cavity.
