Abstract: The present disclosure relates to a detection system for detecting a failure in a fluid path of a fluid system, the detection system including: at least one pipe comprising a pipe wall which defines a fluid path for the transfer of fluid and at least one electrically conductive element extending along the at least one pipe and which forms an electrical signal path for a first electrical signal which indicates a state of the at least one pipe; and, an electrical terminal electrically connected to the at least one electrically conductive element so that the first electrical signal is transmitted to the electrical terminal via the electrical signal path.

Abstract: The invention is directed to compositions and methods for forming conductive patterned coatings of carbon nanotubes. Patterns are electrically conductive coatings/films made by exploiting self patterning nanostructures composed of electrically conductive materials. The resulting layer is suitable for conducting electricity in applications where a transparent electrode is required. Typical applications include, but are not limited to; LC displays, touch screens, EMI shielding windows, and architectural windows. Films may be highly transparent. In one embodiment, carbon nanotubes are applied to an insulating substrate to form an electrically conductive network of nanotubes with controlled porosity in the network. The open area between the networks of nanotubes, increases the optical transparency in the visible spectrum while the continuous nanotube phase provides electrical conductivity across the entire surface or patterned area.

Abstract: This invention relates to flexible, transparent and conductive coatings and films formed using single wall carbon nanotubes and polymer binders. Preferably, coatings and films are formed from carbon nanotubes (CNT) applied to transparent substrates forming one or multiple conductive layers at nanometer level of thickness. Polymer binders are applied to the CNT network coating having an open structure to provide protection through infiltration. This provides for the enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or any combination of both. Polymers may also be insulative or inherently electrical conductive, or any combination of both. Polymers may comprise single or multiple layers as a basecoat underneath a CNT coating, or a topcoat above a CNT coating, or combination of the basecoat and the topcoat forming a sandwich structure.

Abstract: In a writing instrument including an ink reservoir and an air hole, the air hole is spanned by a barrier formed as a porous non-absorbent ink repellent membrane of substantially uniform pore size. The barrier is non-porously sealed, for example by direct heating or ultrasonic welding, along its entire periphery to the wall of the air hole, the barrier allowing air to pass freely therethrough in both directions, but preventing escape of ink therethrough and therearound. The barrier is preferably formed of polytetrafluoroethylene with a pore radius of not more than 10 .mu.m and a thickness of not more than 200 .mu.m. The ink for use in the writing instrument preferably has a surface tension of not less than 30 mN m.sup.-1, a viscosity of not more than 10 cp and a wetting angle with the barrier of not less than 100.degree..

Abstract: An article having a surface comprising an olefin polymer is marked with indicia using an ink comprising a binder capable of substantially complete cure at a temperature of about 100.degree. to 300.degree. C. for less than about 10 minutes and then heated to cure the binder. The indicia are permanent, e.g. are resistant to being rubbed off and are solvent resistant. Heat-recoverable marker sleeves having such permanent indicia are particularly useful for marking wires, e.g. in aircraft harnessing.

Abstract: A writing ink composition having a pseudoplasticity index value between about 0.02 and 0.18, a low-shear viscosity between about 25,000 and 120,000 cP, and a high-shear viscosity between about 6 and 26 cP can be used in a hybrid, ball-point marking instrument which combines advantageous features of both paste-ink and liquid-ink ballpens. The writing ink can be prepared using a colloid milling procedure.
