Abstract: In order to increase the efficiency of a coating process wherein a coating medium such as, for example, powders directed from a coating medium pressure line toward a workpiece to be coated, with the coating process also including an applied electrostatic field, a coating medium which does not adhere to the workpiece is drawn off by way of a suction channel. A flow of the emerging coating medium is bent toward the workpiece that is to be coated by providing a carrier surface profile area between an outlet of the coating medium and a suction channel. By this arrangement a flow velocity gradient between the workpiece to be coated and the profile area is realized with the resulting pressure gradient from the profiled area toward the workpiece.

Provision is made for augmenting surface deposition by electrically charging at least a portion of the gas-borne lubricant particles in such chamber and electrically grounding can bodies individually during passage through such chamber. Endless loop conveyor means are provided with adjustable features enabling a travel path to be adapted to differing dimension can bodies.

Abstract: The difficulty of applying uniform plastic coatings to the interior of pipe and other tubular goods increases in proportion to the diameter and length of the pipe. Epoxy is one of the most satisfactory plastic coatings for use on oilfield pipe. An epoxy coating preferably is applied on powdered form to the heated, rotating pipe interior, where the plastic is fused into a continuous film and thereafter the pipe is cooled as the film solidifies to provide a superior coating which protects the metal pipe surface from chemically reacting with the material flowing therethrough, thereby elongating the life of the pipe.

Abstract: During the axial shirring of tubular casings into shirred strands while the material is inflated with air under overpressure, oil is intermittently injected without propellant air against the inside of the casing, so as to lubricate the inner wall of the casing. This eliminates the need for the costly construction required to provide for the discharge of excess air and oil needed with the known continuous oil injection through two-component nozzle with propellant air, and at the same time it insures a more uniform distribution of oil with reduced oil consumption. The injection nozzle is a single compound nozzle which is connected via electromagnetic valves to a conventional injection pump.
