    摘要： The present invention relates to a process for the hydrocyanation of unsaturated compounds to unsaturated mononitrile compounds or to dinitrile compounds; It relates more particularly to a process for the manufacture of dinitriles by double hydrocyanation of diolefins, such as butadiene, comprising a recovery and separation of the catalytic system. The process for the manufacture of dinitriles of the invention by hydrocyanation of unsaturated compounds, comprising at least one stage of hydrocyanation in the presence of a catalytic system comprising an organometallic complex formed by one or more monodentate organophosphite ligands and one or more bidentate organophosphorus ligands and optionally a promoter of Lewis acid type, comprises at least one stage of separation by distillation of a reactant used in the process or of a compound formed by the reaction from a medium comprising the said catalytic system.

    摘要： The present invention relates to an adjustable air shield for skewed godet rolls. The air shield can be any blocking type plate with or without perforations. Furthermore, these air shields may be placed in close proximity to the pair of skewed, relax rolls in the relax zone of a fiber producing process. The plates are positioned on the inside of the threadline so that the airflow is substantially reduced around the threadline on the skewed rolls. The preferred embodiment of the present invention is one or more skewed godet rolls in the relax area of the fiber production process with air shields positioned on the inside of the fiber string up (threadline) between the pair of skewed rolls, such that the gap between any roll and any air shield is uniform and constant.

    摘要： Short-cut synthetic or cellulose-based natural reinforcing fiber is provided for polymer composites in a form that feeds uniformly into a compounding process such as is carried out in a single or twin screw extruder or double armed batch mixer using conventional volumetric or gravimetric metering equipment. Upon being fed to the compounding process, the reinforcing fiber disperses and becomes uniformly distributed in a matrix resin. The reinforcing fibers are provided in the form of cut fiber bundles with a finish composition coating the fibers and forming fugitive inter-fiber bonds within each cut fiber bundle. This provides inter-fiber coherency such that the cut fiber bundles can be fed uniformly via a loss-in-volume or loss-in-weight screw feeder device to a compounding process. Upon mixing in the compounding process with a matrix polymer, the fugitive bonds break, and the cut fiber bundles disintegrate into separate individual fibers dispersed in the matrix polymer. A process for producing the short-cut reinforcing fiber is also provided.

    摘要： A fabric having a camouflage appearance in the near infrared (NIR) spectrum with a substantially a single color appearance in the visible (VIS) spectrum is provided. The novel fabric may include at least two synthetic polymer multifilament yarns. The multifilament yarns are selected from 3 types of multifilament yarns: multifilaments comprising carbon black, multifilaments comprising pigments which modify the NIR reflectance characteristics of the multifilaments, and multifilaments substantially free of additives capable of modifying the NIR reflectance characteristics of the multifilaments. The fabric is dyed to a substantially single color appearance in the visible spectrum. In general, the fabric has a NIR spectrum comprising two reflectance curves having about 10% to about 85% reflectance separated by about 5% reflectance in a range of wavelengths from about 700 to about 860 nanometers (nm).The fabric may be used to manufacture garments, equipment, tents and tarpaulins that exhibit a camouflage appearance in NIR reflectance observed using night vision devices. At the same time, these garments, equipment, tents and tarpaulins have a single color and substantially non-camouflage in the VIS reflectance spectrum.
