Abstract: An improved plasma spray device which deposits heat fusible material onto a substrate to form a continuous film. The plasma is effected by passing an ionizable gas between two electrodes which support an electric arc. The material to be deposited on the substrate is added to the plasma during its passage through a large nozzle. The gas is directed into a helical path by a plurality of conduits formed in a large disk. The material rides on the cylindrical surface of the revolving gas before being ejected from either a nozzle with a constant interior diameter or a gradually changing diameter.

Abstract: A plasma spray device is described which can be used to deposit heat fusible powdered material onto a substrate to form a continuous film. An electric arc is formed between two electrodes to provide a hot gas plasma which is projected through a nozzle. Powdered fluent material is added to the laminar flowing plasma and is carried on the surface of the plasma during the passage of the plasma through an enlarged nozzle, the powder converging at the tip of the plasma jet. The heat from the arc forms the hot plasma and the powdered material is melted so that the material coalesces to form a continuous film when it strikes the substrate.

Abstract: A POWDER FEED ASSEMBLY HAVING A HOUSING PROVIDED WITH A POWDER RESERVOIR AND A POWDER FLUIDIZING CHAMBER. THE RESERVOIR HAS A SUMP AT ITS LOWER END AND A CONVEYOR IN THE SUMP TO DELIVER POWDER TO THE FLUIDIZING CHAMBER. A CONDUIT DELIVERS A CARRIER GAS UNDER PRESSURE TO THE CHAMBER. ANOTHER CONDUIT CONNECTS THE CHAMBER WITH THE RESERVOIR TO EQUALIZE THE PRESSURE THEREIN AND VALVE MEANS CAN VARY THE PRESSURE. THERE IS ALSO A VALVE FOR RAPIDLY VENTING PRESSURE IN THE CHAMBER INTERMITTENTLY AND A DELIVERY CONDUIT FROM ITS CHAMBER FOR THE FLUIDIZED POWDER.

Abstract: A spray nozzle having a series of helical grooves cut in the outside surface of the nozzle in order to shape and confine the flame ejected from the interior of the gun. The force of the flame draws air through the grooves and thereby provides a helical shield which prevents the flame from spreading and makes it more stable.
