    摘要： A mold tool for forming a reinforced matrix composite part for a gas turbine engine, comprising a body. The body comprises a body surface capable of receiving a first portion of a composite preform. A first endplate and second endplate are attached to the body and include a substantially planar surface disposed perpendicular to the body surface. A first and second set of plates are attached to the first and second endplate adjacent to the body surface and have a geometries that includes a first and second cavity bounded by the first and second plate and first and second endplate. The first and second cavities have a volume sufficient to receive a second portion of a composite preform. The second cavity is in fluid communication with the first cavity, which is in fluid communication with a vacuum source.

    摘要： A protection and control system incorporates status acquisition apparatus for use in monitoring the status of a device in the protection and control system, such as a protection relay in a high voltage electrical circuit. The status acquisition apparatus comprises a conversion circuit which converts an input voltage to a pulse width modulated signal and a comparison circuit which monitors the pulse width modulated signal to determine the status of the device. The mark-space ratio of the pulse width modulated signal decreases as the input voltage is increased to minimize power dissipation over a range of input voltages. The status acquisition apparatus may form an integral part of a protective switching device, although other applications are envisaged.

    摘要： Embodiments of the invention are directed to metal- or metal alloy-coated sheet materials (hereinafter, “metal-coated sheet material”) including, but not limited to, fabrics and veils which have a metal content of between one (1) and fifty (50) grams per square meter (gsm). The metal-coated sheet materials may be used as-is or in conjunction with prepregs, adhesives or surfacing films to provide lightning strike protection (LSP) and/or bulk conductivity, among other benefits, to the resultant composite article. In one embodiment, the metal-coated sheet material is impregnated with a resin. According to embodiments of the invention, a metal is applied to one or two sides of the fabric or veil by a physical vapor deposition coating process. The resultant metal-coated fabric or veil may be used as a carrier in surfacing films to impart surface conductivity; may be used as a carrier in adhesives to form conductive adhesive-bonded joints; may be interleaved (one or more metal-coated veils) between layers of prepreg to impart surface and/or bulk conductivity as well as toughness; or may be used to fabricate composite articles.
