  • Patent number: 10781319
    Abstract: An environmental protective coating (“EPC”) for protecting a surface subjected to high temperature environments of more than 3000 degree F. The coating includes a dense platelet lamellar microstructure with a self-sealing, compliant binder material for holding the platelets together. The platelets may be formed from materials that are resistant to high temperatures and impermeable, such as ceramics. The lamellar microstructure creates a tortuous path for oxygen to reach the surface. The binder material includes engineered free internal volume, which increases the elastic strain of the EPC. The binder is softer than the platelets, which in combination with its free volume increases pliability of the EPC. The binder may have sufficient glass content and glass-forming content for initial and long-term sealing purposes.

  • Patent number: 10771818
    Abstract: An encoder encodes pixels representative of a picture in a multimedia stream, generates a first approximate signature based on approximate values of pixels in a reconstructed copy of the picture, and transmits the encoded pixels and the first approximate signature. A decoder receives a first packet including the encoded pixels and the first approximate signature, decodes the encoded pixels, and transmits a first signal in response to comparing the first approximate signature and a second approximate signature generated based on approximate values of the decoded pixels. If a corrupted packet is detected, the multimedia application requests an intra-coded picture in response to the first approximate signature differing from the second approximate signature. The second signal instructs the decoder to bypass requesting an intra-coded picture and to continue decoding received packets in response to the first approximate signature being equal to the second approximate signature.

  • Patent number: 9731438
    Abstract: A composite article having an elastomeric composition with a blowing agent having an activation temperature and providing at least one structural member defining a fixed gap. The composition is formed below the blowing agent's activation temperature into a solid elastomeric member approximately the thickness of or larger than the gap. The elastomeric member is assembled into the gap, which may place the elastomeric member in a state of compression in the gap. The elastomeric member is then expanded by heating it above the activation temperature. During expansion, the escape of the gas produced is limited to increase the state of compression of the elastomer in the gap by means of confining any free surfaces or by including a platy filler such as nanoclay in the composition.

  • Patent number: 8673398
    Abstract: A method for treating a substrate is described. In accordance with one aspect, the method includes applying a polymer coating to a substrate, and bringing the polymer coating into contact with a heated surface in a pressure nip while the coating is still in a wet state. Optionally the polymer coating may include a crosslinkable material, and a crosslinking agent may be used to promote crosslinking. The polymer coating replicates the heated surface. A product produced in accordance with the described method is also disclosed. The product is characterized by having subsurface voids within the coating.

  • Publication number: 20140039079
    Abstract: The present disclosure provides a porous polymer membrane having a covalent network structure and a method for producing the same. The method includes: polymerizing a first monomer having four first functional groups oriented in a tetrahedral arrangement with a second monomer having at least two second functional groups to prepare porous organic framework nanoparticles; mixing the solution of the porous organic framework nanoparticles with a polymer; and applying the mixed solution to a substrate, followed by heating to form a polymer matrix containing the nanoparticles. According to the method, a polymer membrane with excellent chemical stability, heat resistance, durability and permeability can be produced through simple processes. Advantageously, the porous structure of the polymer membrane can be easily modified depending on intended applications of the polymer membrane.

  • Patent number: 8613978
    Abstract: A method of manufacturing a body structure for a door or other furniture is provided. A skeletal framework is placed on an uncured artificial stone mix deposited on a release sheet placed on a surface. Liquid structural foam is introduced within the skeletal framework. The skeletal framework is wrapped with the release sheet comprising the uncured artificial stone mix such that the skeletal framework is completely covered with the uncured artificial stone mix. The wrapped skeletal framework is placed in a chamber of a defined volume. The uncured artificial stone mix is compressed by the expanding liquid structural foam and conforms to the internal shape of the chamber. The foaming action generates heat that accelerates curing of the uncured artificial stone mix to create an outer cured artificial stone skin of the body structure. After removal from the chamber, the release sheet is separated and the body structure is polished.

  • Patent number: 8518490
    Abstract: In a coating zone, a cylindrical tube is soaked in and taken out from a solution, such that a coating film is formed on a curved surface of the tube. In a wet gas zone, while a first gas feeding nozzle having a gas outlet moves in a state where the gas outlet faces an outer peripheral surface of the tube, wet gas is blown toward the coating film through the gas outlet. Water drops are generated on the coating film and grown up. In a dry gas zone, as in the case of the first gas feeding nozzle, while a second gas feeding nozzle having a gas outlet moves, dry gas is blown toward the coating film through the gas outlet. Solvent and water drops are evaporated from the coating film. Pores form from the water drops as a template for the porous material on the coating film.
