  • Publication number: 20060181344
    Abstract: An intermodulation product reduction or cancellation amplifier received two input signals that are split in quadrature wherein the inphase outputs are summed and then amplified as an inphase signal, and the quadrature outputs are fixed-phase phase-shifted, then summed and then amplified as a quadrature signal. The inphase and quadrature signals are fed into an output hybrid for canceling intermodulation products, where the fixed-phase phase shift is +/?60° for reducing 3rd order, +/?36° for reducing 5th order, and +/?25.71° for reducing 7th order intermodulation products, for examples, for improved signal communications of the two signals over a common antenna or link.

  • Publication number: 20060172132
    Abstract: Gel-spun multi-filament polyethylene yarns possessing a high degree of molecular and crystalline order, and to the drawing methods by which they are produced. The drawn yarns are useful in impact absorption and ballistic resistance for body armor, helmets, breast plates, helicopter seats, spall shields, and other applications; composite sports equipment such as kayaks, canoes, bicycles and boats; and in fishing line, sails, ropes, sutures and fabrics.

  • Publication number: 20060148373
    Abstract: An integrated carrying case and toy object launcher is described. The integrated carrying case comprises a carrying case portion and a launcher. The carrying case portion includes an openable container having a lid and a plurality of compartments. Each compartment is formed to hold at least one toy object. The launcher is connected with and extends from the carrying case portion. The launcher is formed to attach with a toy object and operably connect with a gear rack. The launcher is also formed to impart a rotary motion to the object, such that withdrawal of an operably connected gear rack causes the object to rotate and launch from the launcher.

  • Publication number: 20060035078
    Abstract: High strength polyethylene yarns useful in ballistic-resistant, cut-resistant and other applications, fabrics produced from these yarns and the methods by which the yarns and fabrics are made. An untwisted yarn of the invention comprises a plurality of filaments in essentially parallel array and from about 0.5 to 5 weight percent of a water-dispersible binder material covering less than half the surfaces of the filaments. The yarn has a tenacity greater than about 17 g/d, a tensile modulus greater than about 300 g/d, fewer than 20 entanglements/meter in a scoured state and a width less than given by the formula W?0.055?{square root over (d)} where W is the yarn width in millimeters under a tensile load of 0.01 g/d measured on a flat surface and d is the yarn denier.

  • Publication number: 20050093200
    Abstract: A process for drawing essentially diluent-free gel-spun polyethylene multi-filament yarns in a forced convection air oven and the drawn yarns produced thereby, The process conditions of draw ratio, stretch rate, residence time, oven length and feed speed are selected in specific relation to one another so as to achieve enhanced efficiency and productivity. The drawn yarns are useful in armor, composites, fishing line, ropes, sutures, fabrics and other applications.
