Abstract: A conductive composition for conductive coatings, gap fillers, caulks and fairing compounds that are useful for EMI shielding, electrical grounding, lightning strike protection, and reduced radar cross-section for low observability (LO), with improved resistance to exposure to water, oil and other fluids contains at least one aspartic ester, at least one isocyanate and a conductive filler.

Abstract: A roofing safety system comprises a support assembly adapted to be secured to the roof of a building. The support assembly comprises a central anchor shaft having an upper portion and a lower portion. The support assembly comprises a plurality of struts, each strut having an upper portion and a lower portion, the upper portions of the struts configured to be pivotally coupled to the upper portion of the central anchor shaft. The support assembly comprises a central extension shaft having an upper portion and a lower portion, the lower portion of the central extension shaft configured to be coupled to the upper portion of the central anchor shaft. The support assembly comprises at least one extension arm configured to be rotatably coupled to the upper portion of the extension shaft. The roofing safety system comprises at least one self-retracting lifeline configured to be coupled to the extension arm of the support assembly.

Abstract: A turbofan gas turbine propulsion engine includes a system to transfer power from the low pressure turbine to the high pressure turbine and/or extract additional load from the low pressure turbine during certain turbofan engine operational conditions. The systems include a hydrostatic power transfer system that includes a hydraulic pump and a hydraulic motor coupled to the low pressure and high pressure turbine, respectively. The systems additionally include a mechanical and electrical load shifting/loading sharing systems that use clutches and gear assemblies to share and/or shift load between the turbines.

Abstract: A roofing safety system comprises a plurality of safety cable supports secured along at least a portion of a perimeter of a roof. A safety cable is coupled with, and extends between, at least two of the plurality of safety cable supports. A safety restraint is slidably coupled with the safety cable between at least two of the plurality of safety cable supports.
