    Abstract: An autoclave heating jacket including a heating fluid collar (200), a fluid inlet (120), a fluid outlet (122), and a plurality of fluid flow baffles (202, 204, 206) is claimed. The heating fluid collar (200) can have an outer wall (208) which includes an upper contact surface (210) and a lower contact surface (212) forming an enclosed chamber when engaged with an outer surface of an autoclave. The fluid inlet (120) can be oriented through the outer wall and is capable of directing a heating fluid into the enclosed chamber. The fluid outlet (122) can be oriented through the outer wall but is capable of directing the heating fluid out of the enclosed chamber. The plurality of fluid flow baffles (202, 204, 206) can be oriented within the enclosed chamber so as to direct the heating fluid along a predetermined pathway within the enclosed chamber. Also claimed is a polymerization autoclave comprising said heating jacket and a heating conduit, as well as a method of repairing such an autoclave by replacing some of the weakened or leaking coil segments with said heating jacket.

    Abstract: Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide. The 3- pentenenitrile is made by reacting 1,3-butadiene with hydrogen cyanide. The 1,3- butadiene feed includes a small amount of tertiary-butylcatechol. The catalyst for the reaction of 1,3-butadiene with hydrogen cyanide to make 3-pentenenitrile is recycled. At least a portion of the recycled catalyst is purified by an extraction process.

    Abstract: The present invention is directed to a multi-filament yarn formed at least in part from filaments having cross-sectional zig-zag or double “W “shape with a 180 degree axis of symmetry. The filaments have a denier per filament generally in the range of about 0.1 to about 4.0. Fabrics made from yarns formed with the filaments have high moisture wicking, soft hand, and silk-like lustrous appearance.

    Abstract: A method for producing a spliced yarn comprising alternating predetermined lengths of a first and a second yarn and to the yarn are disclosed.A predetermined length of a first yarn is drawn through an intermingling jet. A leading portion of a second yarn is forwarding into the intermingling jet and into overlapping relationship with a trailing portion of the first yarn. Using a pressurized fluid the overlapped portions of the first and second yarns are intermingled, thereby to splice the leading portion of second yarn to the trailing portion of the first yarn. The first yarn is then severed, and the spliced portion and a predetermined length of the second yarn are drawn through the intermingling jet. The cycle is repeated with the second yarn being the currently drawn yarn and the first yarn being forwarded into overlapping relationship therewith.Preferably the yarns are held in the intermingling jet, as by a clamp disposed forwardly of the jet, while the intermingled splice is formed. The pressurized fluid forming the intermingled splice has a pressure in the range from sixty (60) to one hundred (100) pounds per square inch (413.4 to 689.4 Kilopascals), and more preferably, a pressure in the range from sixty (60) to eighty (80) pounds per square inch (413.4 to 551.2 Kilopascals). Each splice so formed must be able to withstand a tension force of at least 6.8 pounds (3.1 kilograms). The predetermined lengths of the first and second yarn may be equal or different. Preferably the first and second yarns are solution dyed to be differently colored.
