  • Patent number: 10487220
    Abstract: An elastomeric coating composition to enhance or alter the aesthetic appearance of an automobile. The coating composition can be applied by spraying onto either a vehicle paint job or clear coat and is semi-permanent upon drying. The coating composition can be manually removed from the vehicle by peeling without damaging the underlying paint job or clear coat on the vehicle. The coating is made up of a polymer, a mid-block modifier, a tackifier, a thixotrope, a solvent blend, an antioxidant, and a UV stabilizer. A matting agent, static electricity mitigation agent, and a silica suspension agent may also be incorporated into the composition.

  • Patent number: 10239069
    Abstract: A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.

The microtubes assist in wicking moisture directly through a wet mortar compound formed by adding water to the mortar mix. Wicking moisture directly through the mortar decreases the reliance on a continuous, unobstructed cavity behind the masonry wall, as well as prevent cracking from water's freeze-thaw cycle. It also allows water to pass through the mortar in a similar manner as the masonry, creating two in-sync cycles, rather then two disparate cycles for water flow. In various embodiments, the microtubes could be composed of cellulose, fabricated polymer or graphite.

  • Publication number: 20110245358
    Abstract: The present invention relates to a hydrogel contact lens having improved wettability, and particularly to a hydrogel contact lens of a complex membrane having an IPN (interpenetrating polymer network) intra structure, which is prepared by crosslinking composition for a contact lens comprising, as a main ingredient, an acryl monomer and an oligosaccharide and optionally a silicone compound. Due to the presence of an oligosaccharide in a contact lens herein, tensile strength and wettability can be maximized to provide a superior wearing feeling and maintain wettability even after a long-term storage in a care solution such as a washing solution, a storage solution and a protein-removing solution.

  • Publication number: 20110212342
    Abstract: A shape-changing structural member has a shape-changing material, such as a suitable foam material, for example a polymer foam capable of withstanding at least 300% strain or a metal alloy foam capable of withstanding at least 5% strain. Springs, such as one or more coil springs, provide structural support for the shape-changing material. The springs may also be used to provide forces to expand and contract the shape change material. The springs may include pairs of concentric springs, one inside of another. The concentric springs may surround an underlying skeleton structure that supports the shape-changing material and/or aids in changing the shape of the material. The concentric springs may or may not be wrapped around the underlying skeleton structure. Multiple springs or pairs of springs may be coupled together using a sheet metal connector.

  • Patent number: 7989515
    Abstract: Filling foam composition capable of providing excellent rustproofing and also suppressing reduction of a foam ratio of the filling foam composition even when reusing unwanted parts thereof and inferior goods thereof; a foam filling member using the same filling foam composition; and a filling foam produced by foaming the filling foam composition. The filling foam composition is prepared by mixing foamable polymer, a foaming agent, and a basic oxide in such a mixing ratio that a ratio of the basic oxide can be in the range of 0.05-70 parts by weight per 100 parts by weight of foaming agent. The mounting member for the filling foam composition to be mounted in an internal space of a hollow member is produced by mounting a mounting member on the filling foam composition obtained. The filling foam is formed by fitting the foam filling member in the internal space of the hollow member and, then, foaming the filling foam composition by the application of heat.
