Abstract: Disclosed are processes for the conversion of isomerizable halogenated C2-C6 olefins from one geometric form to a more preferred geometric form. Preferred process aspects involve converting C2-C6 olefin in a cis-form to a trans-form under conditions effective to convert at least about 50 percent, and even more preferably at least about 70 percent, of the cis-form compound to the trans-form compound. In preferred embodiments the C2-C6 olefin comprises tetrafluoropropene, with cis-1,3,3,3 tetrafluoropropene (cis-HFO-1234ze) being converted, preferably at high conversion rates and high selectivity, to trans-1,3,3,3 tetrafluoropropene (trans-HFO-1234ze).

Abstract: An abrasion-resistant skirt material for use with air cushion vehicles having at least one air chamber. The sheet material comprises a fabric base comprising yarns of an ultra-high molecular weight polyethylene. A bonding layer, comprising a thermoplastic material is bonded to the fabric base, and an outer layer, comprising a rubber compound is bonded to the bonding layer.

Abstract: The yarns of the invention include untwisted wrapped singles yarns having a core strand and a wrapper yarn. The wrapper yarn is a base synthetic fiber and a heat-activated binder fiber with a melting point substantially below that of the base synthetic fiber. The Saxony carpets of the invention are made from untwisted singles yarn tufts and are possessed of surface appearance, individual tip retention, pile density, resilient hand and wear resistance comparable or superior to conventional Saxony carpets made from multiple plied twist set yarns.

Abstract: A heating apparatus and process useful for drawing ultrahigh molecular weight polyolefin fibers, such as polyethylene fibers. The heating apparatus includes a first set of rolls and a plurality of aligned ovens. The apparatus includes a second set of rolls at the exit of the ovens which rolls are adapted to provide the desired drawing of the polyolefin fibers. The apparatus and process provide a single draw step in a heated environment, with the use of preferably four or six horizontal ovens.

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.

Abstract: Stable concentrated suspensions readily dispersible in water comprising one or more agricultural solids, a single non-ionic surfactant and a water-soluble glycol liquid. The agricultural solids include fertilizers, adjuvants, herbicides, pesticides and combinations thereof approved for use with foods. The non-ionic surfactant is an alkyl-phenoxy-poly(ethylenoxide)alkanol, an ethoxylated aliphatic C11 to C15 alcohol, an ethylene oxide-propylene oxide block copolymer or an ethoxylated fatty acid. Preferably, the surfactant has an average molecular weight from about 300 to about 1000. The water-soluble glycol liquid is ethylene glycol, propylene glycol, or mixtures thereof. The agricultural solid particles are at least about 99 wt. % passable through a Tyler #48 sieve. The suspensions of the invention exhibit physical stability during normal storage conditions, good pourability, and are readily dispersed in water.

Abstract: A process for spinning high molecular weight poly (alph-olefin) filament, particularly ultrahigh molecular weight polyethylene filament, from solution in a volatile spinning solvent with recovery and recycling of the solvent.
