Abstract: An apparatus and method for powder coating the surfaces of objects provides a spray source of charged powder coat particles that engage the surface of the object. The thickness of the layer of particles can be regulated by measuring the resulting electrostatic surface potential generated by the particles. The layer of particles is treated by applying a balanced air flow positively and negatively-charged air ions that neutralize and transport surface particles from the object. The resulting surface has an electrostatic surface potential that is substantially equal thereon. This equal electrostatic surface potential translates into an even thickness coating along the object's surface. The treated surface is then cured by conventional heating and cooling processes to form a finished powder coat finish.

Abstract: An epoxy powder is electrostatically charged and spray-coated onto the series loop connections 16, 18 of a dynamoelectric machine. With the series loop connections grounded, the electrostatically charged particles adhere to the connections and wrap about the front, back and sides of the connections to provide a substantially uniform thickness or build-up of the electrically insulating epoxy powder. With the series loop connections preheated, the epoxy will begin to melt and flow, further ensuring a uniform build-up and thickness about the connections. The spray-coating is then heat-cured, thereby affording electrically insulated series loop connections at the opposite ends of the dynamoelectric machine.

Abstract: A method for the application of chilled particles such as polytetrafluoroethylene generally marketed under the trade mark "TEFLON.revreaction., graphite, molybdenum sulfide and boron nitride to a metal surface having crevices or pores therein. With the metal heated to expand the crevices or pores and the particles chilled to contract them, the particles will be locked into the pores when both the metal and the particles come to equilibrium temperature with the particles thereby expanding and the pores contracting. The method is directed to such an application of chilled particles to expanded pores in large metal objects such as for example, large rolls. The large object is rotated on its linear axis while maintained at the desired temperature and the particles are given an electrostatic charge and chilled prior to their application to the metal surface. Apparatus for effecting this application of electrostatically charged chilled particles includes structure for rotating a large metal object about its linear axis, heating the object, and electrostatically charging and chilling particles prior to their application by spraying to pores and crevices in the metal surface. Portable heating and spraying devices are utilized. Each of the heating and spraying devices is adapted to be moved to a position adjacent the object and to be moved away after performance of its function following which the other device may be moved into a position adjacent the object for performance of its function.

Abstract: Inside the enclosing wall (1) of the electrostatic coating plant for applying dry or wet color coatings to electrically conductive surfaces of articles (2) set up in an insulated position is located an electrostatically chargeable curtain (9), the charge polarity of which is the same as that of the spraying gun (7) used for the coating operation. The article (2) set up in an insulated position is supplied with opposite polarity, which is necessary for the electrostatic coating, by an inductor arrangement (16) arranged above the article (2), the inductor arrangement (16) applying an electrostatic field produced by means of a peak inductor (19) to an electrically conducting layer (18), which is located on the rear of a casing piece (17) made of insulating material. The charge field radiated from the surface of the casing piece (17) brings the article (2) to be coated, suspended beneath the casing piece (17), to a potential at which the material particles located in the spraying jet (8) of the spraying gun ( 7) strike both the front and rear surface sections with approximately uniform distribution.The achieved electrostatic guidance of the coating material particles enables both an optimum utilization of the coating material and a speeded-up operating function of the coating plant.

Abstract: A method of storing tomato paste and like corrosive materials, a method for lining drum shells, lids and filling hole covers, and a lining therefore, prior to the assembly of these parts to make steel drums. The above are carried out by pre-treating such parts by spraying with an alkaline solution, iron phosphate and also can be treated with a standard rust inhibitor. The interiors of the drum parts are coated by electrostatic spray application with a thermosetting epoxy-based powder to a specified thickness which eliminates subsequent cracking and subsequent vulnerability to destructive substances such as tomato paste and other more corrosive chemicals. The drum parts are preheated prior to the application of the powder to accelerate the fusion of the powder particle coating as well as reduce the associated material application problems. After application of the powder to the container interiors, the components are again subjected to oven temperatures to set and cure the coating.
