Abstract: An improved antimicrobial coated product and a method for coating substrates, the product of which is capable of withstanding high impact, is not subject to corrosion, is resistant to germ retention and transfer, and thus is extremely well suited for the containment of toxic, hazardous, corrosive, and bacteria-laden wastes as well as for products which are resistant to attack from fungus, positive and negative bacteria, yeast infections and contaminations, and viruses, as well as resistant to attack from corrosion, corrosive chemicals, caustic chemicals, and radiation. The substrate is coated with a thermoplastic material incorporating an antimicrobial agent by electrostatic, fluidized bed or flame spraying techniques. Alternatively, the substrate may be coated with a combination of a thermosetting resin and a thermoplastic material, either or both incorporating an antimicrobial agent, all of which can be cured in place.

Abstract: Process and apparatus for forming a plastic coating on a metal strip. A metal strip is cleaned, surface treated, coated with an electrostatically charged plastic powder in an enclosed chamber using a plurality of spray guns positioned on both sides of the strip, inductively heated to above the melting point of the powder, and maintained in an infrared heater until the fused powder is flowed into a coating having a smooth surface and a uniform thickness. Thermoplastic and thermosetting coatings, having thicknesses of at least 10 microns formed using total induction and infrared heating times of less than 60 seconds, can be fabricated without cracking.

Abstract: A spraying gun for electrostatic spraying of coating material on an article contains a discharge electrode which is disposed entirely outside the region where the coating material flows. The coating material is accelerated through an annularly shaped and axially extending channel in which the coating material is electrically charged by friction between itself and the insulated walls that define the channel. A gas conduit extends from the discharge electrode and reaches into the annular feed channel of the coating material. Location of the gas conduit between the discharge electrode and the feed channel allows the gas flowing in the gas conduit toward the feed channel to serve the dual purposes of preventing coating material from flowing to and settling on the discharge electrode and providing an electrically conductive path through which undesired electrical charges which develop on the walls of the feed channel discharge to the discharge electrode.

Abstract: A method for selectively applying particles having cores of magnetically-permeable material and outer, fusible surfaces to a lenticular, light-transmissive screen, such as a projection television screen. The particles are selectively deposited in grooves between lenticules of the screen by magnetically attracting the particles to tips of a particle carrier sheet which positionally correspond with the grooves in the screen. The screen is then positioned underneath the carrier sheet, and the magnetic attractive force is reduced to effect release of the particles into the grooves of the screen. Microwave radiation is applied to the screen with the deposited particles, and the magnetically-permeable cores concentrate microwave energy dissipation in the particles and effect selective heating of the particles until their outer surfaces fuse to each other and to the screen.

Abstract: The object is electrically charged to have a first polarity. A dispersion in air of powdered coating is similarly charged to have a like, first polarity and is clouded about the object. The metal object is then suddenly provided with an opposite charge to have an opposite, second polarity, whereupon particles from the cloud are uniformly attracted to and deposited on the object. The powder composition and the technique for fusing the deposited powder to provide a continuous coating may be the same as are in current commercial use.

Abstract: A process for electrostatically applying a multilayered coating on a substrate in one operation or step is disclosed, wherein a mixture of powders of at least two different coating materials is used as the coating composition, each powder, in the case of non-conducting powders, differing from the others in dielectric constant by a factor of at least 0.1, and the powders being of substantially different specific gravities, with the components having the lowest dielectric constant value having the lowest specific gravity value.At least one of the powders will be a powder of a film-forming non-conductive organic or inorganic polymer. Upon electrostatically applying a coating of this powdered composition to a conductive substrate which has a neutral charge or a charge opposite from that of the coating composition powder particles, the powders stratify into distinct layers of different compositions. The powders adhere to the substrate because of contact or static electrification for a reasonable length of time and until at least one of the powders can be cured or fused to form the final coating.Thus, for instance, in only one pass with an electrostatic spray gun, a protective coating of superimposed layers of zinc, epoxy, and polyethylene can be applied to a conductive substrate.

Abstract: A continuous processing system is disclosed wherein glass containers are coated with an exterior protective film of plastic resin which, when cured and quenched as prescribed, provides a clear transparent protective shield against bottle shattering either from internal gas pressures (as when containing carbonated beverages) or from rough external handling as by dropping on a hard surface. The process includes pre-heating of containers, applying powdered resin in a continuous electrostatic spray, passing the spray coated containers through a curing oven, air cooling the cured products and subsequent water quenching and drying before discharge from the system. The foregoing abstract is not to be taken either as a complete exposition or as a limitation of the present invention. In order to understand the full nature and extent of the technical disclosure of this application, reference must be had to the following detailed description and the accompanying drawings as well as to the claims.

Abstract: This disclosure includes a color change means for and method of coating surfaces of articles with a spray of powder particles of one color or a spray including a plurality of different powder particles, the particles being entrained in a gas, such as air. The powder spray device is, preferably, an electrostatic spray device for depositing the particles of powder on a surface to be coated. A plurality of separate passageways in the spray device, one for conveying each powder, are connected to separate sources of powder. Particles of the desired powder or powders are withdrawn from the source or sources containing them. Powder particles flowing into the spray device are conveyed by the passageways to a chamber or compartment within the color change means. A flow of compressed air is introduced to the area where the powder particles emerge from the passageways. An induced flow of air is admitted into the spray device to the rear of termination of the passageways. In operation the powder being sprayed is not retained in the device in significant quantity, a substantially uniform powder distribution is achieved in the spray pattern and the powder particles are provided with momentum sufficient to carry the particles to the vicinity of the surface to be coated.
