Patent number: 9618148Abstract: The invention comprises dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of fittings attached to opposing ends of the tube.Type: GrantFiled: January 5, 2015Date of Patent: April 11, 2017Assignee: Eaton CorporationInventors: Clifton P. Breay, Sara D. Pfannenstiel, Stephen C. Matthews, Edward W. S. Bryant

Patent number: 9136036Abstract: A thermoplastic composite material, which includes a thermoplastic, organic polymer; and a plurality of carbon nanotubes, is provided. The thermoplastic composite material exhibits a bulk volume resistivity of about 103 ?-cm (ohm cm) to 1010 ?-cm at 5,000 volts. Such thermoplastic composite materials may find utility in applications that require the thermoplastic to be capable of withstanding high voltage spikes, as would be encountered during a lightning strike.Type: GrantFiled: July 2, 2008Date of Patent: September 15, 2015Assignee: Miller Waster MillsInventors: Edward W.

Patent number: 5319269Abstract: A stator structure for an electric motor comprising stator windings formed with conductors coated with an insulation, such as polyetheretherketone (PEEK). At least one portion of such windings has an adhesion-resistant agent, such as a thin coat of mineral oil, applied thereto prior to the application thereto of an immobilization agent, such as a varnish. The adhesion-resistant agent prevents subsequent bending of the windings from damaging the underlying insulation thereon during the manufacture and operation of the electric motor. The prevention of such insulation damage reduces the likelihood of resulting premature motor failure.Type: GrantFiled: April 13, 1993Date of Patent: June 7, 1994Assignee: Camco International Inc.Inventor: Edward W.

Patent number: 5260104Abstract: A method and related apparatuses are disclosed for coating an elongated filament, such as wire, wherein wire is coated with a heated coating material, such as polyetheretherketone (PEEK), and the coated wire is maintained at a temperature and for a period of time sufficient for a desired quantity and size of crystals to form in the coating material and to minimize internal residual stress. Thereafter, the coated wire is rapidly cooled to a temperature below its crystallization temperature, such as in a quenching bath. A crystalline PEEK coating results which has minimized internal residual stress, is less brittle, and has improved cracking, peeling and abrasion resistance over amorphous PEEK coating obtainable using prior methods.Type: GrantFiled: November 25, 1992Date of Patent: November 9, 1993Assignee: Camco International Inc.Inventors: Edward W. S. Bryant, Isaac T. Reidland
