    摘要： The invention relates to a process for separating dimethyl isophthalate (DMI) and dimethyl orthophthalate (DMO) and other by-products from their mixture with dimethyl terephthalate (DMT), formed in the oxidation of p-xylene followed by esterification with methanol, by crystallization from the melt.Initially, the esterification product is here distilled once or several times. The DMT-rich fraction obtained is then subjected wholly or partially to one or several crystallizations from the melt, and the DMI-DMO fraction thus obtained is at least partially removed from the system. As an alternative, the DMT-rich fraction is first recrystallized from methanol, the methanol is then evaporated from the mother liquor and the remaining residue is subjected to one or several crystallizations from the melt. The DMI-DMO fraction thus obtained is again at least partially removed from the system.

    摘要： A method and apparatus for producing a ribbon free randomly wound yarn package is disclosed, and wherein a plurality of critical winding ratios at which undesirable pattern formations or ribbons would normally occur are determined and stored in a microprocessor control unit. During the winding operation, the spindle speed and traversing frequency are monitored by sensors and are transmitted to the control unit, and the control unit computes the optimum time for rapidly changing the traversing frequency so that the actual winding ratio moves rapidly through each of the approaching critical winding ratios. The original traversing frequency is re-established after having passed beyond each of the critical winding ratios.

    摘要： An automatic spool-changing system for textile machines with an array of high-speed winding heads, for example of the type having a spool revolver and a lossless thread transfer device. The system has a conveyor moving along the machine front and a spool changer with a gripper movable between the conveyor and a spool holder in a spool-changing position. The conveyor is located below and in generally the same vertical plane with the spool holder, and the gripper, which is arranged for both rotation and axial translation, is mounted for movement along a three-legged spool doffing and spool-donning path extending forwardly of the machine front. Two embodiments are shown. In the first, a separate empty-spool magazine is provided and the conveyor merely serves to carry away the empty spools. In the second, the conveyor serves for the transportation both of full spools and empty spools; in this case the gripper has two angularly displaced heads so that it can execute a spool-doffing and spool-donning operation simultaneously. Controls for the spool-changing system are also disclosed.

    摘要： A method and apparatus for winding a continuously advancing yarn, wherein the yarn is wound into a package that is formed on a rotating tubular core, the yarn being traversed by a yarn guide within a traverse stroke. At the beginning of each traverse stroke, the yarn guide is accelerated within a reversal length to a guiding speed, and after traversing the traverse length it is decelerated within a second reversal length. The yarn traversing mechanism includes a belt drive system for reciprocating the yarn guide and which is controlled by a programmable control device such that the yarn guide is moved within a traverse stroke which is axially shorter than the package length and which is reciprocated between the ends of the package without changing the length of the traverse stroke.
