  • Patent number: 9102572
    Abstract: A method of forming a concrete wall having a substantially uniform exterior surface texture. The method includes the initial step of pouring concrete into a wall form. The concrete is poured from a first mixture and is allowed to cure. After the concrete is cured, the wall form is removed from the resultant concrete base structure. A roughened texture is then created on the base structure. A finishing mixture is then applied to the roughened texture. The finishing mixture may be created by separating the aggregate from a portion of the remaining first mixture. The finishing mixture creates a smooth texture on the exterior surfaces of the initially formed base structure.

  • Patent number: 8637587
    Abstract: Release agents with increased affinity toward nano-imprint lithography template surfaces interact strongly with the template during separation of the template from the solidified resist in a nano-imprint lithography process. The strong interaction between the surfactant and the template surface reduces the amount of surfactant pulled off the template surface during separation of a patterned layer from the template in an imprint lithography cycle. Maintaining more surfactant associated with the surface of the template after the separation of the patterned layer from the template may reduce the amount of surfactant needed in a liquid resist to achieve suitable release of the solidified resist from the template during an imprint lithography process. Strong association of the release agent with the surface of the template facilitates the formation of ultra-thin residual layers and dense fine features in nano-imprint lithography.

    Abstract: In a method for injection molding molten materials, especially plastic, in a mold that has a mold surface which comes into contact with the material, at least one coating on the mold surface and a temperature-control means for the mold surface, the mold surface is cooled by the temperature-control means so that the molten material solidifies at the interface with the coating and an injection-molded part can be removed from the form. During this process the molten material is brought into contact with the coating on the mold surface, the thickness of said coating being selected in coordination with the heat penetration coefficient of the coating material such that a specified 60° gloss level and/or color value L is obtained for the injection-molded part.

  • Patent number: 8444901
    Abstract: The present application discloses a progressive cavity motor or pump component, either stator or rotor, which provides a high glass transition temperature polymeric surface on the component which becomes resilient at or below the expected operating temperature of the motor or pump, but which remains solid at ambient temperatures, along with a method of fabricating either a stator or a rotor with such surface characteristics. Since the surface becomes resilient, the progressive cavity pump operates efficiently at temperatures above the glass transition temperature of the selected polymeric surface.

  • Publication number: 20130034698
    Abstract: Disclosed herein are a flexible substrate with surface structure and a method for manufacturing the flexible substrate. The disclosure relates to a low-cost process to manufacturing the flexible substrate that is adapted to the large-area mass production. According to one of the embodiments in the disclosure, the method introduces a mold with surface structure. An isolation material is formed on the mold surface in an earlier stage. Upon the isolation layer, a flexible substrate material is coated. After that, a baking step is employed to cure the flexible substrate material. The flexible substrate with surface structure is therefore formed after de-molding the cured substrate. Another aspect to the disclosure adopts the above-formed substrate to be a base substrate. A second flexible substrate with the surface structure identical to the mold is then formed by performing the above steps.

  • Patent number: 8337740
    Abstract: A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers. The wetted fibers are arranged on pressurizable members and may be configured to include internal structural features, such as shear webs. A reinforcement stiffener may be located adjacent to at least one of the pressurizable members and the wetted fibers that form the internal structural feature. The reinforcement stiffener includes a modulus of elasticity that is substantially higher than a modulus of elasticity of the resin used to wet the fibers. In one embodiment, the reinforcement stiffener may be received in a pocket of one of the pressurizable members and may include a releasing agent that permits removal of the stiffener after the composite structure has been pressurized and cured.
