20080286472 | REDUCING FORMALDEHYDE EMISSIONS - A method for reducing formaldehyde emissions from articles prepared from, or which otherwise comprise formaldehyde-emitting compositions, such as formaldehyde-containing resins, and relates especially to a method for reducing formaldehyde emissions from products such as cellulose laminates, permanent press (wrinkle-free) textiles, floral foams and ceiling or acoustical tiles, which involves isolating the article in an enclosed space a formaldehyde scavenger, particularly a formaldehyde scavenger carried by a substrate. | 11-20-2008 |
20090142496 | METHOD FOR FABRICATING REINFORCED COMPOSITE MATERIALS - A method for fabricating a reinforced matrix composite comprising the step of providing a composite preform having a fibrous structure and applying matrix material onto the preform in locations along the preform. A barrier material is applied to at least a portion of the coated preform to direct the flow of matrix material into the preform. The composite preform is heated to a temperature sufficient to render the matrix material viscous and insufficient to cure the matrix material. The pressure to the interior of the composite preform is reduced, while the pressure to the barrier material is increased. The temperature is maintained to flow the matrix material into the composite preform and to force gases from the fibrous structure. The composite preform is then cured and cooled to form a reinforced matrix composite having a low void content and a substantially uniform matrix distribution. | 06-04-2009 |
20110223337 | Extrusion coating apparatus and coating method as well as coating film forming method - The present invention provides an extrusion coating apparatus which can control the coating shape in end portions regardless of the coating thickness and can suppress high edges. The extrusion coating apparatus includes a coating width regulating plate inserted into both end portions of a slit, a slit die discharging the coating solution from a discharge opening of the slit, and a chamber depressurizing in a web running direction on an upstream side. The coating width regulating plate has a protruded portion bent toward the web downstream side and facing the web. The coating solution is applied to the web in a state in which the coating solution is oozed on a web facing surface of the protruded portion of the coating width regulating plate by depressurization of the chamber. | 09-15-2011 |
20140363578 | APPARATUS AND METHOD FOR QUANTITATIVELY COATING CATALYST SUPPORT - Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support. | 12-11-2014 |
20150336172 | A METHOD OF PRODUCING A METALLIC BODY PROVIDED WITH A METALLIC CLADDING - A method of producing a metallic body provided with a metallic cladding includes the steps of providing a hollow body including a bottom wall and a lateral wall that presents an inner space, filling the space with a metallic cladding material that will form the cladding, positioning the hollow body in a metallic capsule, closing the metallic capsule and evacuating air from the interior of the latter, and applying an elevated pressure and an elevated temperature on the outside of the capsule, such that the cladding material is bonded to the hollow body. The capsule is coaxial with the hollow body and has a lateral inner periphery that has a shape and dimension that corresponds to the shape and dimension of the outer lateral periphery of the hollow body. The hollow body with the core therein is formed in a machining operation in which material is removed from a blank of a solid piece of metal material. | 11-26-2015 |
20160090500 | Method for fabricating a semicrystalline polymer / graphene oxide composite film - The present invention discloses a semicrystalline polymer/graphene oxide composite film, comprising: a first semicrystalline-typed polymer, distributed in structural space of the composite film and having a porous structure; and graphene oxide, having a layered structure and distributed in the composite film wherein gas passage exist between adjacent layered structures, the first semicrystalline-typed polymer existing between part of adjacent layered structures forms into a second semicrystalline-typed polymer by further heat treatment after the first semicrystalline-typed polymer and graphene oxide are blended uniformly to be distributed in the composite film so as to fill and seal a portion of the porous structure to block gas from flowing to extend path length(s) of gas passage; wherein graphene oxide existing between the first semicrystalline-typed polymers induces formation of the second semicrystalline-typed polymer. | 03-31-2016 |
