Abstract:
A distribution manifold having a manifold and a removable cartridge with a plurality of needle tubes extending from the removable cartridge is disclosed. The distribution manifold can be used with a pre-metered coating system to apply coating material to a substrate.
Abstract:
A slurry application device according to an aspect of the invention includes a slurry supply unit, a slurry application unit, and a slurry adhesion amount adjustment unit. The slurry supply unit supplies slurry onto a surface of a traveling base material. The slurry application unit presses a first roll body against slurry of a surface of a base material to apply the slurry onto the surface of the base material and to adjust a slurry adhesion amount such that a film thickness of the slurry of the surface of the base material becomes one time or more and two times or less of a target film thickness. The slurry adhesion amount adjustment unit presses a second roll body disposed at the downstream side in a travel direction of the base material in relation to the first roll body against the slurry of the surface of the base material to adjust the slurry adhesion amount such that the film thickness of the slurry of the surface of the base material becomes the target film thickness.
Abstract:
A method for coating a carbon fiber for a composite structure may comprise applying a slurry onto a surface of the carbon fiber, wherein the slurry is a sol gel comprising a metal precursor and a carrier fluid, and heating the carbon fiber to a temperature sufficient to form a sol gel-derived layer on the carbon fiber. The slurry may comprise a metal precursor such as a metal salt or a metal alkoxide. The sol gel-derived layer may help prevent the carbon fiber from oxidizing. The metal precursor comprises at least one of aluminum nitrate, calcium nitrate, aluminum isopropoxide, aluminum sec-butoxide, aluminum oxide, tetraethylorthosilicate (TEOS), zirconium n-propoxide, and titanium isopropoxide.
Abstract:
A process is provided for treating wood products including lumber, plywood and other engineered wood products comprising the steps of applying an aqueous fire-retardant impregnate and applying a coating to the surface of the wood product. In one embodiment, said process confers fire-retardant properties to the wood products sufficient to pass the extended burn test of ASTM E-84. The present invention also provides fire retardant wood products.
Abstract:
Apparatus to apply a coating to media. The apparatus (14) includes a first roller (20) for receiving a continuous belt (23). The continuous belt is for receiving a coating from a second roller (27) and for transferring the coating to media (12). The first roller (20) is arranged to provide an adjustable width of the continuous belt (23) to the second roller (27). The width of the continuous belt (23) provided to the second roller (27) is adjustable to substantially correspond to the width of the media.
Abstract:
A clean version of the amended Abstract is shown as follows: There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.
Abstract:
The invention relates to a process for selectively treating parts of the surface of a porous dental zirconia article, the process comprising the steps of providing a liquid composition and a porous 3-dimensional dental zirconia article having an outer and inner surface, applying the liquid composition to only a part the outer surface and/or inner surface of the porous dental zirconia article, the liquid composition comprising a whitening agent comprising a phosphorous containing component, the phosphorous containing component comprising a phosphate, phosphone or phosphine moiety, with the proviso that at least one P—O unit of the phosphate, phosphone or phosphine moiety is dissociable or able to otherwise interact with zirconia. The invention also relates to a dental zirconia article obtainable or obtained by such a process and a kit of parts comprising a container containing a certain liquid composition.
Abstract:
The purpose of the present invention is to apply a hot-melt adhesive in a thin-film state only to top surfaces of pattern roller protrusions. This roller transfer application method for a hot-melt adhesive is characterized: in that a coater head having a slot in a direction towards an axis center of the roller is provided facing a pattern surface of the pattern roller; and by supplying the hot-melt adhesive, which is supplied from a hot-melt adhesive supply device, in a thin-film state to a pattern top surface of the pattern roller, and thus the thin-film hot-melt adhesive is only supplied to the top surfaces of pattern roller protrusions. This method is further characterized by supplying the hot-melt adhesive only to the top surfaces of the pattern roller protrusions by opening an on-off-type hot-melt adhesive supply control valve, which is attached to the coater head, when an adhesive opening on the bottom surface of the coater head is facing application zones on the pattern surface of the pattern roller. The present invention has the effect of satisfactorily maintaining a work environment by preventing contamination of the device periphery.
