Abstract:
Machine (1) for the plasma treatment of containers (3), which comprises: a chamber (5) suitable for receiving a container (3) to be treated, a cover (8) defining a nozzle (9) in the extension of the chamber (5); a duct (14) for depressurization the container (3), which duct opens into the nozzle (9) and connects the latter to a vacuum source (15); a first valve (19) having a closed position, in which it closes off the depressurization duct (14), and an open position, in which it brings the nozzle (9) and the vacuum source (15) into communication; a duct (27) for pressurizing the container (3), separate from the depressurization duct (14), this pressurization duct (27) emerging in the nozzle (9) beyond the depressurization duct (14) and connecting the nozzle (9) to a pressure source (28); and a second valve (29) having a closed position, in which it closes off the pressurization duct (27), and an open position, in which it brings the nozzle (9) and the pressure source (28) into communication.
Abstract:
The present invention relates to a method for the selective coating of a surface of a substrate with liquid, wherein the surface to be selectively coated with liquid comprises regions exhibiting different surface energies, and wherein prior to wetting a fluorine-containing plasma gas is directly acting on the regions exhibiting different surface energies.
Abstract:
A robotic spray system is provided for accurately spraying mold release onto any size or shaped green tire. The system analyzes individual green tires using an integrated vision system. The system controls the robotic spray position, the fan, fluid, atomizing air, and tire rotation speed for optimal spray coverage on both the inside and outside of green tires. The system includes a conveyor, an overhead mounted camera located over an infeed station, and a second camera located perpendicular to the green tire's tread and several feet away from the center of the tire. Pictures of the green tire in the station are used to estimate the center and radius of the tire and locate the angle of the bar code with respect to the center of the tire. Reference points are provided from the camera images and robot positions are calculated to control the spraying.
Abstract:
Medical catheters are often coated, fully or partially. The present invention relates to systems and methods for coating some portion or all of a medical catheter or one or more of its components.
Abstract:
A method of manufacturing an optical functional film including an application step of applying a resin solution onto a substrate film made of a thermoplastic resin and an immobilizing step of immobilizing a resin applied to form a resin layer, characterized by that it further comprises, prior to the application step, a stretching step of stretching the substrate film with the substrate film kept heated.
Abstract:
A method for manufacturing an optical film comprising a transparent substrate and at least one functional layer on or above the transparent substrate, wherein said at least one functional layer to be laminated on the transparent substrate is formed by a layer-forming method comprising the following steps (1) and (2): (1) step of applying a coated layer on the transparent substrate, and (2) step of curing the coated layer by irradiating ionizing radiation in an oxygen environment in which the oxygen concentration is lower than an atmospheric oxygen concentration.
Abstract:
An article of a plastic substrate and a bond layer of a plasma polymerized cyclosiloxane having select unsaturation and a method of forming same.
Abstract:
Coated articles are formed by applying a first aqueous solution or dispersion of a thermoplastic resin on a surface of an article and at least one IR curing catalyst to form a film, where at least a portion of the first aqueous solution or dispersion is a thermoplastic epoxy resin. The film is exposed to IR radiation in an amount sufficient to at least partially cure the film, and a substantially cured and/or dried thermoplastic epoxy coating is formed.
Abstract:
The invention relates to a process for producing an object which has optical layers. According to the invention such a process comprises the following process steps: To a substrate of plastic material several optical layers are applied; the optical layers are applied by means of a chemical plasma-impulse vaporization (PICVC).
Abstract:
An open-ended tube comprising walls of a heat-sealable multi-layer polymeric film, wherein said film comprises an outer shrinkable substrate layer and an inner heat-sealable layer, wherein said substrate layer has a degree of shrinkage in the longitudinal dimension of the tube of about 0% to about 50% over the temperature range 55 to 100° C., and a degree of shrinkage in the transverse dimension of the tube of 5 to about 70% over the temperature range 55 to 100° C.; and use thereof in the manufacture of packaging for a container suitable as a receptable for a ready-prepared ovenable meal.
