    Abstract: A knitted spacer fabric has a tightly knitted bottom layer, a more loosely knitted upper layer and linking fibres extending across the space between the lower and upper faces. Settable material, e.g. cement, is introduced into the space between the upper and lower faces and can be caused to set by the addition of a liquid, e.g. water. Until set, the fabric is flexible and can be shaped but after the material in space has set, the fabric is rigid and can be used as a structural element in a wide range of situations. The bottom layer has an extension that extends beyond the upper face and is connected to the upper face by elastic connecting fibres that draw the extension towards the other face, thereby at least partly closing the space at the edge of the cloth and preventing the settable material from spilling out.

  • Patent number: 8697186
    Abstract: A process for manufacturing a mask having submillimetric openings, in which: for a masking layer, a first solution of colloidal nanoparticles in a first solvent is deposited, the particles having a given glass transition temperature Tg, the drying of the masking layer, known as the first masking layer, is carried out at a temperature below said temperature Tg until a mask having a two-dimensional network of substantially straight-edged submillimetric openings, that defines a mask zone known as a network mask zone is obtained, a solid mask zone is formed by a liquid deposition, on the face, of a second masking zone, the solid mask zone being adjacent to and in contact with the network mask zone, and/or at least one cover zone is formed, the cover zone being in contact with the network mask zone, and/or after the drying of the first masking layer, a filled mask zone is formed by filling, via a liquid route, openings of a portion of the network mask zone.

  • Patent number: 8663973
    Abstract: The invention relates to microscopic structures and methods of making and using the structures. A method of forming a microscopic structure of a material includes obtaining a solution (310) containing the material, establishing a flowing stream of the solution (310) in a capillary (104), wherein the capillary (104) has an inner dimension that is smaller than about 300 micrometers, and maintaining the stream until a layer is built up along an inner wall of the capillary (104) from material deposited from the flowing stream, thereby forming a microscopic structure.

  • Publication number: 20140034179
    Abstract: A system of insulation and jacketing of industrial equipment is provided comprising an insulation layer comprising one or more layers of insulation applied to an outer surface of the equipment and a jacketing layer applied and adhered to an outer surface of the insulation layer. An outer surface of an outermost layer of insulation is conditioned to form a smooth outer surface and promote adhesion of the jacketing layer to the insulation layer. A method of insulating and jacketing industrial equipment is also provided comprising the steps of applying an insulation layer to an outer surface of the equipment, conditioning an outer surface of an outermost layer of insulation and applying and adhering a jacketing layer to an outer surface of the insulation layer. Conditioning the insulation layer serves to smoothen the outer surface and promote adhesion of the jacketing layer to the insulation layer.

  • Publication number: 20130306737
    Abstract: The invention relates to a security tag made unique by randomly distributing a mixture of large numbers of multicolored small objects, such as two colored glass balls, into a regular geometric array or pattern onto a substrate and encapsulating those objects. The objects in the regular array on the substrate will create a unique, non-reproducible pattern. The data, saved to a secure database, can be processed and calculated quantities can be derived from the field of binary data, which can be affixed to the document or manufactured part that the stamp is affixed to. The regular array can be read out by scanner, quantities calculated, and compared to the values printed on the part or document. Additionally, the regular array can be read out by optical scanner and parts or all of the data compared to the data stored in the secure database.

  • Publication number: 20130309409
    Abstract: There is provided a coating for a body of steel or a carbon fiber reinforced plastic material with an adhesion-promoting layer of thermoplastic that is deposited on the body, in the surface near material matrix of which solid particles are embedded in a form-fitting adhering manner such that a partial region of particles projects from the adhesion promoting layer. For producing such a coating, the adhesion-promoting layer is heated to a honey-like viscosity, and powder particles are injected by thermal spraying, into the surface near material matrix of the heated adhesion-promoting layer in a form-fitting adhering manner such that the tips of particles project. These tips connect to deposited powder particles which form the functional layer of oxide ceramic such as Al2O3, Cr2O3, TiO2, SiO2 or ZrO2 or mixtures therefrom and/or wear resistant hard metal such as WC/Co, Cr3C2/NiCr, NiCrBSi, WC/Ni, TiC/Ni, molybdenum, or chromium or mixtures or alloys thereof.

  • Patent number: 8580337
    Abstract: An article may be fabricated by coupling a thermoplastic to a bonding interface layer, and applying a coating layer to the surface of the bonding interface layer. A bonding interface layer may comprise catalytic nanoparticles embedded within and/or encapsulated by one or more radiatively unstable polymers. Application of ionizing radiation to the article may release a catalyst at the bonding interface. Application of heat and/or stress to the article may enhance catalytic degradation of the remaining bonding interface and uncoupling of the thermoplastic from the coating layer. Embodiments of methods, compositions, articles and/or systems may be disclosed.

  • Patent number: 8563081
    Abstract: Fabrication and arrangement of nanoparticles into one-dimensional linear chains is achieved by successive chemical reactions, each reaction adding one or more nanoparticles by building onto exposed, unprotected linker functionalities. Optionally, protecting groups may be used to control and organize growth. Nanoparticle spheres are functionalized in a controlled manner in order to enable covalent linkages. Functionalization of nanoparticles is accomplished by either ligand exchange or chemical modification of the terminal functional groups of the capping ligand. Nanoparticle chains are obtained by a variety of connectivity modes such as direct coupling, use of linker molecules, and use of linear polymeric templates. In particular, a versatile building block system is obtained through controlled monofunctionalization of nanoparticles.
