  • Patent number: 10576663
    Abstract: Very good impregnation quality is achieved by a process for production of a fiber-composite material, with introducing a fiber layer by a spreader device and thus spreading to a width greater than that of the final product, at least by a factor of 1.2, where the extent of spreading of the fiber layer is such that its average thickness is 1 to 50 times the filament diameter; applying a melt by at least one applicator nozzle to the spread material; by virtue of cross-section-narrowing, the mould brings the width of the wetted fiber layer at least to the cross section with which the product leaves the take-off die; a radius then deflects the wetted fibers by an angle of 5 to 60°; a relaxation zone renders the fiber distribution more uniform to give a uniform height; achieving the first shaping by a take-off die at the end of the mould.

  • Patent number: 10160892
    Abstract: Solid compositions made from or coated with a non-melting organic polymer having a main glass transition temperature of at least 65° C., few if any isocyanate groups and a wet aged glass transition temperature of up to 60° C. are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these compositions will self-bond. The compositions can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These compositions are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.

  • Patent number: 9707727
    Abstract: The manufacturing of articles relies on the bonding of two or more components to form some forms of the articles, such as a shoe sole bonded with a shoe upper. The bonding may be achieved with an adhesive particulate that is applied to a surface of a substrate. The adhesive particulate is selectively fused to the substrate with a controlled energy source having multiple energy emitters individually controllable, such as a laser array. The selective application of laser energy allows for specific geometric structures of adhesive particulate to be formed on the substrate. The substrate having the fused adhesive particulate is mated with another component allowing the fused adhesive particulate to bond the first substrate and the second component.

The method includes encapsulating a desired beneficial agent as a core material in a polymeric microcapsule, and transferring polymeric microcapsule to the surface by a dipping, spraying, or padding application. The beneficial agent, after getting transferred to the surface of a hard flocked article, imparts long lasting performance, provides fragrance and may protect an article from odor, insect, pest, fungi, bacteria, viruses, and the like. The polymeric microcapsules deliver long lasting benefits to surfaces with flocking, such as clothes hangers. Also described is a process for manufacture of flocked items with benefit delivering polymer microcapsules, without the need for binders or adhesives. Benefit agents are released with shear force on the flocked surface, so they are released when used and provide long-lasting performance.

  • Patent number: 8020508
    Abstract: The present invention is a process for uniformly depositing nanomaterials having particles smaller than 1 ?m (i.e., nanoparticles) onto a surface of a base material (substrate or surface). The process is used to deposit any solid (nanoparticle) of any shape such as nanofibers, nanotubes, nanoclays (e.g., platelet shaped), nano-spheres, or irregularly shaped granules. The base material upon which the nano-particles are deposited can be made of any material. The method substantially prevents the deposition on the base material of larger particles (contaminants or clusters of the nanoparticles) which are often mixed with the nanomaterials. The amount of deposition and the range of particle sizes to be deposited can also be controlled by this method.

  • Publication number: 20110143094
    Abstract: The process of the present invention significantly increases the durability of superhydrophobic surfaces, while retaining similar optical properties to those of the original surface. The process uses velocity and heat to take freshly formed nano- and ultrafine particles and can partially embed and chemically bond them to the substrate, creating a strongly bonded nano-to-submicron textured surface. This nanotextured surface can then be modified to have desirable surface properties; for example, it can be hydrophobic, oliophobic, or hydrophilic. The high points of the coating made with this process protect the remainder of the surface from abrasion, thus greatly increasing product life in many uses. In preferred embodiments, the process is used to coat transportation vehicle windshields.

  • Publication number: 20110123713
    Abstract: A filter support casing and filter provides powder into a Bernoulli flow system. The system has an upper end and a lower end, the upper end having an opening therein. The filter support casing extends downward from the upper end. There is a filter supported within the casing. The filter support casing and the filter define an internal volume within both the filter support casing and the filter. The volume is exposed to the opening in the upper end and as later explained is flow connected into a gas stream that will carry particles and spray particles. The casing has at least two concentric elements, a first inner elements and a second outer element, that rotate with respect to each other and which slide with respect to each other. The two elements rotate about their concentric positions and slide along their lengths. The first inner element is contiguous (adjacent and/or touch and adjacent) with the filter. The first inner element encloses the filter with arms (fingers, extensions, posts, etc.

  • Publication number: 20110097507
    Abstract: A method for establishing a calibrating standard for wafer inspection includes depositing solid ionized particles of a known size range with an aerosol onto a wafer. The method also includes depositing particles onto a wafer in a deposition chamber by using an aerosol stream and the solid particles suspended in a gas; ionizing the aerosol stream with a negative or positive charge polarity or both by passing the aerosol stream through a non-radioactive ionizer to produce charged particles and supplying such aerosol stream to the deposition chamber.

  • Publication number: 20110068291
    Abstract: A novel method to develop highly conductive functional materials which can effectively shield various electromagnetic effects (EMEs) and harmful radiations. Metallized nanotube polymer composites (MNPC) are composed of a lightweight polymer matrix, superstrong nanotubes (NT), and functional nanoparticle inclusions. MNPC is prepared by supercritical fluid infusion of various metal precursors (Au, Pt, Fe, and Ni salts), incorporated simultaneously or sequentially, into a solid NT-polymer composite followed by thermal reduction. The infused metal precursor tends to diffuse toward the nanotube surface preferentially as well as the surfaces of the NT-polymer matrix, and is reduced to form nanometer-scale metal particles or metal coatings. The conductivity of the MNPC increases with the metallization, which provides better shielding capabilities against various EMEs and radiations by reflecting and absorbing EM waves more efficiently.

  • Publication number: 20100303564
    Abstract: A method of creating adherent, fracture-toughened polycrystalline diamond coatings on carbide cutting tools or other workpiece substrates through the development of composite coatings comprising polycrystalline diamond and carbon nanotubes is described. The coating is deposited through a chemical vapor deposition process using a pre-determined hydrocarbon-hydrogen gas mixture suitable for nucleating diamond on the carbide particles and carbon nanotubes on the metallic binder. The deposited coating, which may be up to 30 micrometers in thickness, is typically characterized by a diamond or diamond-like carbon matrix in which carbon nanotubes are distributed as fiber-like filler materials.

  • Patent number: 7842340
    Abstract: A fiber unit coating apparatus includes a chamber into which an uncured resin coated fiber unit is passed. Microspheres mixed with air are fed into the chamber via ducts and apertures. As a result rapid and even application of the microspheres can be achieved, and the system allows controllable application of the microspheres by varying the rate of flow of the air/microsphere mixture. Positive pressure chambers are provided to prevent the microspheres from blocking the inlet and outlet points where the fiber unit enters and leaves the chamber.
