摘要： A process for preparing ultra-high molecular weight poly(alpha-olefin) (UHMWPO) multi-filament yarns having improved tensile properties at higher productivity. The process includes drawing a solution yarn, then drawing a gel yarn and then drawing a dry yarn continuously in sequence to form a partially oriented yarn, winding up the partially oriented yarn, unrolling the yarn, drawing the partially oriented yarn to form a highly oriented yarn, cooling the highly oriented yarn under tension and winding up the highly oriented yarn.

摘要： 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.

摘要： Methods and devices to actively apply finish to one or more yarns in motion at speeds greater than about 3000 m/min, to achieve a finish application of 0.2 wt % or more with a coefficent of variation of finish concentration of 10% or less, and the finished yarns so produced. The devices are compact, portable and readily installed at a variety of positions on a fiber processing line, such as between heated godet rolls. The devices contain the finish so that contamination of the surrounding areas is prevented. The yarn products of the invention may be used in textile and leisure fiber applications and in industrial fiber applications, such as tires.

摘要： Embodiments of present invention provide a WDM device which includes a first element having a first right surface and a first top surface; and a second element having a second left surface and a second bottom surface, wherein the second bottom surface is bonded together with the first top surface and the first right surface is coated with a WDM filtering coating which is adapted to, upon incident of an optical signal having at least a first and a second wavelength, cause the first wavelength of the optical signal to exit the first element at the first right surface, and cause rest of the optical signal to be reflected back into the first element, pass through the first top surface and the second bottom surface, and enter the second element. A method of making the WDM devices is also provided.

摘要： The present invention relates to a method for accurately detecting oscillations and improving stability of power systems. The method includes the steps of providing a phase-locked loop having a phase detector, a loop filter, and a number-controlled oscillator. The method further includes the steps of extracting an input signal from the power system, using the phase-locked loop to track the frequency and phase of a targeted mode in the input signal, and creating a locally generated reference signal to fit the input signal and to allow the input signal's modal information to be obtained. The method further includes the step of performing mode shape analysis utilizing the reference phase signals constructed from the tracked frequencies.
