A repair process for an article such as an airfoil includes providing an article that has a substrate and a ceramic barrier coating disposed on the substrate, where the ceramic barrier coating has a damaged region, abrading the damaged region to provide dimple in the ceramic barrier coating, wherein a remaining region of the ceramic barrier coating adjacent the dimple remains intact, and depositing a patch of networked ceramic nanofibers in the dimple.

An apparatus for curing concrete includes a multiple layer film and an absorbent layer. The film can include pH modifying components and antiskid components. The absorbent layer can include pH modifying components. The apparatus can be applied to concrete after hydration water is applied. The apparatus can enclose concrete members during transport so as to continue the curing process during transport. The film can be used as a barrier layer between the ground and poured concrete. The apparatus can be manufactured by heating a film to its crystalline softening point, applying adhesive material to an absorbent material, and adhering the film to the absorbent material. A method of curing concrete includes pouring concrete, waiting for the concrete to reach the bleed stage, providing hydration water, adding a pH modifying component to the hydration water, and applying the hydration water with the pH modifying component to the poured concrete.

Provided is a system, method, and apparatus for forming surface designs in hard-setting materials. The method includes depositing a hard-setting material mix to create a construction component, controlling a movable unit to manipulate a surface of the construction component with a first profile tool arranged on the movable unit based on surface design data before the hard-setting material mix sets, and controlling the movable unit or at least one other movable unit to manipulate the surface of the construction component with a second profile tool arranged on the movable unit or the at least one other movable unit based on the surface design data before the hard-setting material mix sets, wherein the second profile tool comprises a blade edge and a trowel edge.

The present invention relates to a method for the automated production of a workpiece having at least one diaphragm, including a workpiece for an electrochemical sensor, including providing a workpiece that has a wall with at least one continuous opening through the wall, wherein a diaphragm body is affixed in the at least one opening, such that the diaphragm body completely fills a cross-section of the opening, and processing the diaphragm body by means of a laser.

A cement-based tile formed from a mixture comprising: a cement in the range of about 0.1 to 88% by wet weight percent; a secondary material in the range of about 0.1 to 50% by wet weight percent, the secondary material comprising limestone, sand, silica sand, gypsum, silica fume, fumed silica, Plaster of Paris, calcium carbonate, fly ash, slag, rock, or a combination thereof; a reinforcement fiber in the range of about 0.5 to 20% by wet weight percent, the reinforcement fiber comprising cellulose fiber, glass fiber, plastic fiber, polypropylene fiber, polyvinyl alcohol (PVA) fiber, homopolymer acrylic fiber, alkali-resistant fiber, or a combination thereof; a rheology modifying agent in the range of about 0.5 to 10% by wet weight percent; a water in the range of 10 to 60% of a total wet material weight; and wherein the mixture is extruded or molded to form the cement-based tile.

An apparatus for curing concrete includes a multiple layer polyolefin film and an absorbent layer. The polyolefin film layer can include pH modifying components and antiskid components. The absorbent layer can also include pH modifying components. The absorbent layer can include nonwoven fabric. The apparatus can be applied to curing concrete after hydration water is applied to the curing concrete. The apparatus can also be used to enclose poured concrete members during transport of the members so as to continue the curing process during transport. The film can also be used as a barrier layer between the ground and poured concrete.

An imprinting film for a building material, and a system and method for use of the same are disclosed. In one embodiment of the imprinting film, a transparent film has first and second imprinting states. In the first imprinting state, a first side of the transparent film includes a pigment photomask defining an image and a second side includes a mold receiving surface. In the second imprinting state, the second side includes a relief of the image on the mold receiving surface. The mold receiving surface is configured to receive a molding material and the molding material hardening into the building material. The transparent film transitions from the first imprinting state to the second imprinting state in response to the second side being coated with a light-sensitive, non-laminate adhesive layer and a light source irradiating the first side.

A method for manufacturing a honeycomb structure includes a tubular circumferential wall and partition walls forming a honeycomb-shaped cross-section and defining a plurality of cells extending inside the circumferential wall in the axial direction of the circumferential wall. The method includes a molding process, a degreasing process, and an impregnation process. The molding process molds a mixture including ceramic particles, an organic binder, and a dispersion medium to obtain a molded body. The degreasing process removes the organic binder included in the molded body to obtain a degreased body. The impregnation process impregnates the inside of the circumferential wall and the partition walls of the degreased body with metal silicon. The impregnation process is performed under an inert gas atmosphere or a vacuum at a temperature between 1400 C. and 1900 C.

Various embodiments for a median barrier finishing machine are described.
