    摘要: Method of selectively removing volatile components from a composition, comprising coating the composition onto a first substrate surface of a substrate, wherein the composition comprises a nonresident volatile component and a resident volatile component. The method further includes positioning at least a portion of the coated substrate between a condensing surface having a condensing surface temperature and a heating surface having a heating surface temperature that is greater than the condensing surface temperature, wherein the condensing surface is in a spaced apart, confronting relationship to the coated surface of the substrate and wherein the heated surface is in thermal contact with a second substrate surface opposite the first substrate surface. In the method, the heated surface temperature and the condensing surface temperature are such that the positioning step causes the nonresident volatile component to be selectively removed from the portion of the coated substrate. The method is suitable for forming transdermal drug delivery compositions.

    摘要: An ultrasonic-assisted injection molding system and method for making precisely-shaped articles. A source of ultrasonic energy is positioned to apply vibrational energy to a mold cavity connected to at least one gate in flow communication with a source of molten (co)polymer. The mold is heated to a temperature of 104-116° C., and the molten (co)polymer is injected into the mold cavity. After cooling the mold until the molten (co)polymer within the gate has solidified, ultrasonic energy is applied to the mold without remelting the solidified (co)polymer within the gate until the temperature increases to 116-122° C., thereby substantially relieving flow induced stresses. The mold is then cooled until the temperature decreases to 101-107° C., and is thereafter heated until the temperature increases to 116-122° C., thereby substantially relieving any thermally induced stresses. The mold is cooled until the molten (co)polymer has solidified, thereby forming a precision molded plastic optical element.

    摘要: A system(109) for altering charge of a dielectric material (90) uses ultraviolet radiation. The system includes a gas source (102) and an ultraviolet radiation source (104). The gas source (102) introduced a gas (103) to a region adjacent the dielectric material (90). The ultraviolet radiation source (104) is arranged to irradiate the region to adjust charge on the dielectric material. A method of altering charge on a dielectric material (90) is also disclosed in which a gas (103) is introduced to a region adjacent the dielectric materia (90)1. The region is then irradiated with the ultraviolet radiation (105) to alter charge on the dielectric material (90).

    摘要: A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-substrate contact area. An electrical force is created on the fluid from an electrical field (originating from electrical charges which are on the second side of the substrate) that is substantially at and downstream of the fluid wetting line. The electrical field can be generated by charges that have been transferred to the second side of the substrate from a remote charge generator.
