  • Patent number: 9017810
    Abstract: A method is provided for producing an electrical insulation paper having a particle composite. The method involves mixing a dispersion of particles in platelet form, a carrier fluid and a functionalizing agent which is distributed in the carrier fluid and has a proportion by mass in the dispersion corresponding to a predetermined mass ratio based on the proportion by mass of the particles. The dispersion is sedimented, such that the particles in platelet form are arranged in essentially plane-parallel layers in the sediment. The carrier fluid is removed from the sediment. Energy is introduced into the sediment to overcome the activation energy of that chemical reaction of the functionalizing agent with the particles which forms the particle composite from the sediment with coupling of the particles via the functionalizing agent. The mass ratio is predetermined such that the particle composite has a porous structure. The insulation paper is thereby produced.

The sealing mastic surrounds the cable about the sheath terminal edge and overlaps portions of the metal sheath and the oil barrier tube adjacent the sheath terminal edge to effect an oil barrier seal between the metal sheath and the cable core at the sheath opening. The pressure retention tape surrounds the sealing mastic to limit displacement of the sealing mastic.

  • Patent number: 8257536
    Abstract: A method and apparatus for a tray, a folding section connected to the tray, and a tape application system. The tray has a channel for receiving an elongate insert for a composite material with a number of layers for a release system. The folding section is capable of folding a number of layers around the elongate insert to cover the elongate insert as the elongate insert is moved through the folding unit. The tape application system is capable of applying a tape to the number of layers for covering the elongate insert to form the release system.

  • Patent number: 8141592
    Abstract: A system and method of repairing a pipe including securing a reinforcing material, such as a dry fiber structure (e.g., a carbon fibers) to the surface of the pipe. A polymeric material is placed on top of the reinforcing material, self-penetrating the dry fiber structure. The polymeric material substantially saturates the reinforcing material and cures to form a reinforced polymeric composite which may increase or restore the pressure rating or operating pressure capacity of the pipe. Optionally, an outer containment component, such as a sleeve, shell, box, wall, outer pipe, and so on, may be installed around the reinforcing material prior to introduction of the polymeric material. In this case, the polymeric material may be placed (i.e., poured) into the interior of the containment component on top of the reinforcing material.

  • Publication number: 20120043004
    Abstract: An apparatus for making a carbon nanotube composite structure includes a supply unit, a wrapping unit, and a collecting unit. The supply unit is configured to supply a linear structure. The wrapping unit includes a drive mechanism, a hollow rotating shaft, and a face plate. The drive mechanism is mounted on a first end of the hollow rotating shaft to drive the hollow rotating shaft. The face plate is fixed on a second end of the hollow rotating shaft and loads a carbon nanotube array with a growing substrate. The carbon nanotube array forms a carbon nanotube structure. The wrapping unit winds the carbon nanotube structure around the linear structure. The collecting unit pulls the linear structure and collects the carbon nanotube composite wire structure.

  • Publication number: 20110139329
    Abstract: A flexible circuit comprises a folded dielectric sheet having conductive patterns on its surface(s) to which microelectronic device(s) are attached. The dielectric sheet is folded 180° about a selected axis and a bond layer joins the two halves over a portion of their respective surface areas so that a remaining portion of their areas remain unbonded and a bifurcated structure is thereby formed. Electrical contacts are provided on the unbonded or bifurcated portions of the flexible sheets. The flex may be attached to a rigid frame and provided with protective heat spreading covers. The folded flex design is particularly suitable for reel-to-reel manufacturing.
