Abstract: The present invention relates to a method for enhancing the efficiency of digitally communicated data exchanges and to a computer system that implements such a method. The invention particularly concerns the use of adaptive custom compression techniques, binary integers (“bits”), massively parallel processing, database optimization techniques and/or calculation optimization techniques to achieve such enhanced efficiency. The invention is applicable to any digitally communicated data exchange, but is particularly applicable to exchanges of financial information such as financial market buy/sell orders, market making, etc.

Abstract: The present description discloses a polymeric composition which is a melt-processed alloy comprised of (a) a polyarylene sulfide resin, (b) a polyaryl-ether-ketone resin, and a reactive compound which results in (c) a graft copolymer of the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin in addition to the starting resins. Exemplary melt-processed polymeric compositions can be made by reacting an alkoxy silane with the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin to produce a graft copolymer of a portion of one or both of the resins, sufficient to render the composition uniform and homogeneous. It is normally preferred for the exemplary organosilane compound, to be an amino silane. The subject invention further reveals an insulated wire comprising (1) an electrical conductor and (2) a layer of the melt-processed alloy composition; and fiber reinforced composites comprising fibers substantially fully impregnated with the alloy polymeric composition.

Abstract: Spunbonded fabrics are formed by melt-spinning a blend comprised of a major amount of an uncured substantially amorphous polyarylene sulfide and a minor amount of a crystallinity enhancer to obtain a nonwoven mass of filaments, and thereafter passing the nonwoven mass of filaments through a nip of heated calendering rolls to form a spunbonded fabric therefrom having at last substantially crystalline surface regions. Preferably, blending minor amounts of a polyolefin (e.g., polypropylene) with an uncured polyarylene sulfide (e.g., polyphenylene sulfide) allows spunbonded nonwoven fabrics to be formed which do not suffer from the drawbacks noted above. More specifically, spunbonded fabrics formed of a blend of PPS and polypropylene may be calendered (bonded) at temperatures greater than between about 110 to about 125° C. (preferably greater than about 140° C.), and exhibit lengthwise and widthwise shrinkage after heatsetting at 120° C. for 3 minutes which is less than about 5%.
