    Abstract: The present invention is a method for covering an object with a film resulting from the melting of a thin layer of powder, in which method comprises: (a) having a bed of electrified fluidized powder in a tank, this powder being charged by a forced-circulation tribocharging device; (b) dipping the object, connected to zero or sufficient potential, into the tank in order to cover it with powder; (c) placing the object, covered with the powder, in an oven at a temperature high enough to obtain the coating film by melting the powder. According to one advantageous embodiment of the invention, the oven includes electrodes raised to a high electrical potential so as to cause a corona effect which compensates for the relaxation of the charge on the powder particles while they are being heated. The charge on the particles is maintained and therefore they remain on the object and thus can form the film by melting. The present invention also relates to the apparatus for implementing the method.

    Abstract: A high-throughput lithography process for creating high-resolution patterns in a polymerizable composition using carefully controlled electric fields followed by curing of the polymerizable composition is described. The process involves the use of a template that includes the desired patterns. This template is brought into close proximity to the polymerizable composition on the substrate. An external electric field is applied to the template-substrate interface while maintaining a uniform, carefully controlled gap between the template and substrate. This causes the polymerizable composition to be attracted to the raised portions of the template. By appropriately choosing the various process parameters such as the viscosity of the polymerizable composition, the magnitude of the electric field, and the distance between the template and substrate, the resolution of the structures formed in the liquid may be controlled to conform to that of the template.

    Abstract: A system and process for electrodynamic powder coating of conducting and non-conducting substrates using an electrodynamic fluidized bed. The system generally includes a coating applicator means for applying charged particles to the substrate to be coated, and postcharging means for applying to the substrate an additional charge of such polarity as to cause an increase in the electrostatic forces holding the coating particles to the substrate. The system further includes a precharging means for precharging the substrate with a charge of such polarity as to effect more uniform coating of the substrate and a higher rate of coating. Where the substrate to be coated is a continuous web, the system includes a conveying means for conveying the web through the various positions adjacent to the three aforementioned means. The coating applicator means may be an electrodynamic coating apparatus of the electrodynamic fluidized bed type and comprising a fluidized bed means and a charging bed means with a porous wall positioned therebetween, and a recharging means.
