Abstract:
Disclosed are methods for forming nanoparticle films using electrophoretic deposition. The methods comprise exposing a substrate to a solution, the solution comprising substantially dispersed nanoparticles, an organic solvent, and a polymer characterized by a backbone comprising Si—O groups. The methods further comprise applying an electric field to the solution, whereby a nanoparticle film is deposited on the substrate. Suitable polymers include polysiloxanes, polysilsesquioxanes and polysilicates. Coated glass windows and methods of forming the coated glass windows using the solutions are also disclosed. The methods may be adapted to form nanoparticle films suitable for use as back reflectors in solar cells, where such nanoparticle-based back reflectors exhibit high reflection and light scattering properties, including use of such back reflectors to fabricate solar cells and other photovoltaic-based and light dependent devices such as television screens, computer monitors, portable systems such as mobile phones, handheld games consoles and PDAs.
Abstract:
A disclosed digital media device operational at user premises to receive media signals from a media source for presentation via endpoint devices such as a television display. The digital media device can include gateway and digital media management functionality and can be referred to as a gateway and digital media device. The device offers application services obtained over a wide area network and a user premises network. The digital media device may form a composite signal from the media signal and application service information, for example, for a composite audio and/or video signal for television type presentation to the user. The digital media device may receive a selection signal based on the presentation, for transmission to the application service provider device or to the media source. The media device also offers a GUI presenting a moveable arrangement of icons for selectively accessing application services.

Abstract:
A method for making a composite panel, wherein the composite panel has a honeycomb core sandwiched between a pair of facing sheets, includes the steps of (a) coating the interior walls of the cells with a unexpanded thermo-expandable material; (b) bonding a pair of facing sheets to the opposite sides of the honeycomb core; and (c) heating the honeycomb core while the honeycomb core is sandwiched between the pair of facing sheets with sufficient heat to cause the thermo-expandable material to expand and to substantially fill the cells.
Abstract:
A system and process is disclosed for binding particles to a carrier material in an isolated relationship for use in composite fabrication. A slurry comprising particles dispersed in fluid is created in particle suspension tanks, deposited as a uniform layer and filtered using reduced pressure applied to a filter belt to leave behind isolated particles, the reduced pressure further acting to overcome electrostatic and other forces of attraction between the particles until they can be permanently bound to the carrier with a binder or adhesive and collected on a take-up roll.
Abstract:
A system and a method for providing a film having a matte finish. The system includes means for providing a coated substrate, the coated substrate comprising a first coatable material applied to a substrate, the coatable material forming a first major surface of the coated substrate; means for changing the viscosity of the first coatable material from a first viscosity to a second viscosity; a face-side roller having an outer surface positioned to contact the first major surface of the coated substrate to impart a matte finish thereon; and optionally, means for hardening the first coatable material. The method of the invention includes the steps of (1) providing a coated substrate comprising a coatable material disposed on a substrate, the coatable material providing a first major surface of the coated substrate; (2) changing the viscosity of the coatable material from the initial viscosity to a second viscosity; (3) contacting the first major surface of the coated substrate with at least one face-side roller to impart a matte finish; and (4) optionally, hardening the coatable material to provide the film.
Abstract:
The invention relates to a curtain coating process for coating substrates with a stable curtain and a uniform coating at low flow rates wherein a free-falling curtain of an aqueous composition comprising a high solids content is coated onto the moving substrate at a flow rate per unit die length value (Q) equal to or inferior to 10−4 m2/(s·m), the said high solids content composition comprising a polymeric rheology modifier and a non-ionic surfactant. The invention relates in particular to a curtain coating process for coating fibrous substrates such as paper or board. The invention also relates to a coated product.
Abstract:
A method for operating a machine for single or double sided application of a liquid or viscous coating medium by way of at least one applicator unit onto the surface of a mating material web, especially a paper or cardboard web is provided. The coating medium collecting unit is cleaned prior to, during or after an application process of the machine, by way of supplying cleaning liquid via the supply line. The valve arrangement can be switched to the second valve condition for clean-up and to the third valve condition for the collection of coating medium in the medium collecting device. The medium collecting unit can be cleaned after start of the application process, during coating, through elements of supplying cleaning liquid via the supply line.
Abstract:
A method of applying a multilayer coating film, in which two or more layers of coating film are applied to a flat plate, such as steel plate, by baking finish, which method is effective for preventing of foam generation; and a product with multilayer coating film obtained by the method. There is provided a method of applying a multilayer coating film, including discharging paint films through multiple slits, simultaneously applying these films to a traveling plate to thereby form a multilayer paint film and carrying out drying or baking thereof, characterized in that with respect to the boiling points of solvents contained in adjacent layers of the multilayer paint film, there is such a relationship that the boiling point of solvent contained in the layer close to the plate is equivalent to or lower than the boiling point of solvent contained in the layer remote from the plate, and that the boiling point of solvent contained in the layer closest to the plate is lower than the boiling point of solvent contained in the layer remotest from the plate.
Abstract:
A wide slit nozzle having a slit as a discharge opening. The thickness of a lateral end part is set smaller than the thickness at a lateral center part. The thickness of the lateral center part is fixed. The thickness of the lateral end part changes linearly from opposite lateral ends of the lateral center part to the opposite lateral ends of the slit. Coating material is discharged from the slit while applied with pressure, so that the coating material is coated while expanded wider than the width of the slit. The coating material is discharged at 7 liter per minute, and a coating width of a first example is 100 mm, for example. A thickness increase of the overlapped part is +25% even when a width or an overlapped margin z of the overlapped part is 10 mm or 20 mm.
