165 Curative fibre components US13140055 2009-11-24 US09926418B2 2018-03-27 Mark Raymond Steele; Andrew Gibbs; Amy Grace Atinkson
Curative fibre components comprise one or more fibres for filaments of curative suitable to cure curable resins such as thermoset resin. In curative fibre components comprising a plurality of fibres of curative, the fibres can be commingled, such as twisting, to form a thread or yarn. Curative fibre components can be used to form a material in the form of a sheet, fabric, layer, textile or mat of woven or non-woven curative fibres. Curative fibre components can be used to produce composite materials such as fibre reinforced resinous composite materials. The curative fibre components can be commingled, including interwoven, stitched and layered with other fibres or fibrous materials, such as fibrous reinforcement, fibrous curable resin, fibrous thermoplastic, other non-reinforcing fibres to form composite materials, prepregs, preforms and articles.
166 Preparation methods of filter element for swift and highly efficient adsorption of CS US14267457 2014-05-01 US09206529B2 2015-12-08 Zhenfang Dong; Deyi Ma; Hongqi Shi
A preparation method of filter element for swift and highly efficient adsorption of Cs includes the following steps: to a substrate material, adding a coupling agent with 1-3 wt % and ammonium phosphomolybdate with 1-10 wt %, based on the weight of the substrate material; heating to 160˜220° C.; stirring and mixing evenly so that the substrate material is combined with ammonium phosphomolybdate; spining through 5 μm micropore, the spun filament forming adsorbent filter element with a thickness of 5˜50 mm in the rotational cylinder framework material; evenly coating ammonium phosphomolybdate on the outer surface of the adsorbent filter element; and stabilizing and implementing an aging process by heating to 80˜120° C. for 3-12 h. The filter element prepared by this method provides an excellent water permeability, oxidization resistance, long-term immersion in hot water of below 100° C., radiation decomposition resistance, stable adsorption, swift detection, high efficiency and precision.
167 Device and process for producing a reinforced hollow fibre membrane US13427052 2012-03-22 US08999454B2 2015-04-07 Steven Kristian Pedersen; John David Ireland
A nozzle for making a reinforced hollow fibre membrane discharges one or more reinforcing yarns at or near a plane where the dope exits the nozzle, or in the same plane as a discharge opening of dope passage, or both. Multiple discrete yarn discharge openings may be spaced around a longitudinal axis of the nozzle. A reinforcing yarn passage remains generally free of dope during use. The dope may be discharged in an annular ring inside of the one or more reinforcing yarns, in an annular ring outside of the reinforcing yarns, or both. Minimal tension is required to pull the yarns through the nozzle, which helps to reduce distortion of the membrane cross section in a coagulation bath.

172 Process for the manufacture of short fibrils US541622 1975-01-16 US4010229A 1977-03-01 Jean-Pierre Pleska; Michel Marechal
A process is provided for the manufacture of fibrils of short length by suddenly releasing the pressure acting on a two-phase liquid mixture of molten polymer and solvent and which is at a high pressure and a high temperature. The two-phase liquid mixture is ejected through a pressure release orifice so as to vaporize the solvent instantaneously and solidify the polymer, and the flow path of the two-phase liquid mixture is perturbed at the instant when it enters the pressure release orifice.Spinnerets are provided which have a perturbation chamber containing a supply orifice and a pressure release orifice.

178 Apparatus for removing moisture from a section of polymer filament US16395180 2019-04-25 US20190330766A1 2019-10-31 Dennis Joseph Steibel, JR.; Richard David Fraser
The present invention is an apparatus used for the removal of moisture from of a section of polymer filament just prior to its consumption by an external process. The apparatus removes moisture by heating the polymer filament in a controlled manner to a temperature which releases the moisture from the polymer filament, but below the temperature that significantly distorts the polymer filament so that the mechanical structure of the polymer filament (diameter and linearity) is substantially maintained. As the polymer filament is externally consumed, it moves through the apparatus. The apparatus removes moisture from polymer filament more rapidly than other methods.
