Abstract: A robust process for the continuous preparation of solutions of high molecular weight UHMW PO that is capable of producing strong materials at high production capacity, is conservative of capital and energy requirements, and the articles made therefrom.

Abstract: A method and system for ensuring scanning of suspicious computer files without unnecessary caching of the files on a network device is provided. A network device receives a suspicious computer file and determines whether a target computer is protected by a malware protection program. If the network device determines that the target computer is protected by the malware protection program, the network device modifies the suspicious computer file to make the suspicious computer file unusable by the target computer and sends the modified suspicious computer file to the target computer.

Abstract: 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.

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.

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.
