Abstract: A method for electrostatic spray-coating a medical device having a tubular wall, such as a stent, having an inner surface, an outer surface and openings therein. The tubular wall is grounded or electrically charged, and an electrically charged conductive core wire is located axially through the center of the stent. An electrical potential is applied to the conductive core wire to impart an electrical charge to the conductive core wire. The tubular wall is exposed to an electrically charged coating formulation, and the electrically charged coating formulation is deposited onto a portion of the tubular wall to form a coating. The electrical potentials of the conductive core wire and tubular wall can be repeatedly alternated.

Abstract: A substrate including at least one anisotropic property in at least one of an X-, Y-, and Z-direction. The anisotropic property includes a predetermined gradient applied by a migration of electrostatically charged droplets. The anisotropic property can be applied as a fluid on the substrate formed as a film or web or laminate in which the substrate is located between two spaced apart electrodes for generating an electrostatic field. An electrostatic field is generated on each side of substrate and a fluid is introduced as droplets for application to the substrate into the electrostatic field on at least one side of the substrate, forming electrostatically charged droplets. The electrostatically charged droplets are directed based upon a predetermined pattern onto the at least one side of the substrate. In accordance with one embodiment, the electrode on the side opposite to the side on which the droplets are introduced is used to cause the droplets to migrate into the interior of the substrate.

Abstract: An apparatus for electrostatically coating powder on a flat panel and a method for using such apparatus are provided. In the apparatus, a heating device is used to heat a panel to be coated and positioned on a powder spray chamber to a temperature of at least 100° C. and simultaneously charging the panel with a negative voltage of at least 20,000 volts. The high temperature and the high voltage of the otherwise non-conductive panel result in a panel that is electrostatically conductive. Powder particles that are charged with a high positive voltage are then injected toward the panel surface by an air pressure of at least 0.8 kg/cm2 until particles are adhered to the panel surface. The present invention novel method can be used advantageously at low costs due to its simple processing steps and as an environmentally friendly process since no solvent needs to be evaporated and released into the atmosphere. The present invention novel method further provides a low cost method for fabricating flat panel display devices due to its simplified processing steps.

Abstract: A composite manufacturing system moves a multi-fiber tow through a processing space. A resin particle source provides particles to the space. This source may include an airstream entrained with particles which is discharged into the space through an orifice; the airstream diverging as it enters the space. An electrode is disposed in the space to electrostatically charge the particles and facilitate deposition of the charged particles on the tow. In one embodiment, the electrode includes a corona wire disposed proximate to the tow to provide a generally cylindrical charging region. An electric field useful to direct deposition of the particles may be generated by appropriately shaping a wire electrode and orienting it in a predetermined manner relative to the tow. After the particles are deposited, a fixation unit may be used to at least partially melt the deposited particles. A processing stage may be included which has a pair of surfaces configured to heat and compress the tow therebetween. Multiple post-deposition processing stages to heat and compress the tow may be employed to improve resin impregnation among fibers of the tow.

Abstract: Powder coatings are described which are curable by means of exposure to radiation, typically ultraviolet radiation, in a form suitable for deposition onto substrates, typically by means of electrostatic deposition. It is expected that such powder coatings would be particularly useful in coating heat sensitive substrates since the necessity for heating the powder coating to elevated temperatures is not necessary to effect cure. Free radical curing coatings are described using specific chemical formulations of acrylourethane resins, unsaturated polyester resins and mixtures thereof in combination with morpholino containing photoinitiators, phenol containing photoinitiators, and ketal containing photoinitiators.
