Abstract: Novel conformable adhesive tapes consisting essen­tially of: (1) a water-impermeable backing layer from about 1 to 3 mils thick; (2) a flame-retardant, evenly tearable synthetic fibre cloth or scrim; (3) a flame-­retardant adhesive layer, preferably a rubber-based adhesive; and (4) a thin tie coat layer between the backing and the scrim which, when applied as a molten mass, at least partially fills the interstices between the fibres of the scrim so as to provide surface contact with the underlying adhesive layer, the tie coat providing a strong bond at both the tie coat/­backing interface and the tie coat/scrim and adhesive interfaces, thereby providing a laminar product possessing the desired anchorage and structural stability and integrity. 
     The tape is particularly useful in wrapping irregular surfaces, e.g. as a wire harness wrap, where conformability is essential to good adhesive contact.

Abstract: A system and method are disclosed for wireless two-way communication in a cased borehole having tubing extending therethrough. A downhole communications subsystem is mounted on the tubing. The downhole subsystem includes a downhole antenna for coupling electromagnetic energy in a TEM mode to and/or from the annulus between the casing and the tubing. The downhole subsystem further includes a downhole transmitter/receiver coupled to the downhole antenna, for coupling signals to and/or from the antenna. An uphole communications subsystem is located at the earth's surface, and includes an uphole antenna for coupling electromagnetic energy in a TEM mode to and/or from the annulus, and an uphole receiver/transmitter coupled to the uphole antenna, for coupling the signals to and/or from the uphole antenna. In accordance with a feature of the invention, the annulus contains a substantially non-conductive fluid (such as diesel, crude oil, or air) in at least the region of the downhole antenna and above. An advantage of the disclosed communications links is that transmission losses can be kept relatively low, since the annulus between the tubing and the casing has been filled with a non-conductive fluid. The relatively high efficiency of the transmission link facilitates battery-less operation or operation with a rechargeable battery. This can be achieved by transmitting power downhole and using the received power downhole as a source for a downhole power supply that energizes the downhole equipment and/or charges a downhole rechargeable battery. The disclosed communications system, also benefits from use of a spread-spectrum coding scheme, employed, which is found to be particularly effective in accurately carrying information over the transmission link, even in the presence of conditions that cause substantial interference. In one disclosed embodiment, the coding scheme is adaptive to take account of changing conditions of the transmission path. It is further demonstrated that communications can continue, even in the presence of shorts between the tubing and casing.

Abstract: Prepreg precursors and other normally non-flowable resinous semi-solid or viscous liquid polyimide precursor compositions often need to be transformed into free-­flowable liquids without dilution and without causing changes in their chemical composition. Such compositions are composed of (a) a diester of an aromatic tetracar­boxylic acid, (b) an aromatic diamine, (c) a polyamic acid producible from (i) an aromatic diamine and (ii) a dian­hydride of an aromatic tetracarboxylic acid, and (d) an inert solvent in an amount insufficient to provide a flowable liquid at room temperature. Such compositions readily undergo chemical change (amidization and imidiza­tion) when subjected to heating in a conventional oven because of local overheating, and poor heat transfer within the body of the composition. These problems are overcome by subjecting the composition to microwave radiation of intensity sufficient to convert at least a portion of the composition into a flowable liquid without causing a significant change in its chemical composition.

Abstract: A highly reflective surface coating on a substrate (W) is formed by a coating method in a coating line. A paint is sprayed (P2) on the substrate in a viscosity of 18 seconds or lower when measured by means of Ford Cup #4 at 20°C in a film thickness thicker than a thickness at which the paint sags, the paint containing a solvent or solvents, having a boiling point as high as 110 °C or lower in an amount of 50% by weight or higher. 
     After completion of the spraying (P2), a coat of the paint is dried by a drying step including sequential setting (P3) and baking steps (P4). The substrate (W) is held in an ambient temperature during the setting step which is lower than the ambient temperature during the baking step, and the rotation of the substrate in the drying step being carried out about its horizontal axis at a speed which is high enough to rotate the substrate (W) from a vertical position to a horizontal position before the paint coated thereon substantially sags due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force, thereby allowing the coat formed thereon to achieve a substantially sagless state. 
     This coating method prevents the paint from swelling on an edge portion of the substrate (W) forming a mass, whereby a coat surface is provided with a high degree of flatness.
