    • An improvement in a high speed process to produce high performance multi-end polyester yarn comprises extruding molten polyester from a spinnerette to form filaments, then cooling, lubricating and advancing the filaments to a forwarding roll system at the speed of from about 1000-4000 meters per minute so that a partially oriented yarn is produced, then feeding the filaments from the forwarding roll system to a first draw roll system to partially draw the yarn, then feeding the paritally drawn yarn to a second draw roll system having a draw point localizing device then feeding the filaments from the draw roll system to a conditioning roll system and finally taking up the filaments. The improvement is the use of matte finish on godet rolls having an arithmetic mean roll surface roughness value of from between about 35 microinches and about 120 microinches to feed and withdraw yarn to and from a draw point localizing device in the second draw roll system. This combination enables multiple ends of the filaments to be advanced through a single set of forwarding, drawing and conditioning rolls and yarn mechanical quality remains at a high level of acceptance.
    • 制造高性能多端聚酯纱线的高速工艺的改进包括从喷丝头挤出熔融聚酯以形成长丝,然后以约1000-4000米的速度冷却,润滑并将长丝推进到前辊系统 每分钟使得产生部分取向的纱线,然后将长丝从前辊系统供给到第一拉伸辊系统以部分地拉伸纱线,然后将经纱拉出的纱线送入具有拉伸点定位装置的第二拉伸辊系统 然后将长丝从拉伸辊系统供给到调理辊系统,最后卷起长丝。 改进之处在于使用具有约35微英寸和约120微英寸之间的算术平均辊表面粗糙度值的导丝辊上的无光泽处理以在第二牵引辊系统中从拉丝定位装置进出纱线。 这种组合使得长丝的多个末端能够通过一组前进,拉伸和调节辊前进,并且纱线机械质量保持在高水平的接受度。

    • High molecular weight linear condensation polyesters are stabilized against deterioration by heat by reacting the polyester in molten form with certain polycarbonates in the presence of a catalytic amount of a phosphonium compound selected from the group consisting of tetra-n-alkylphosphonium acetates and tetra-n-alkylphosphonium halides. For the purpose of this disclosure, polycarbonates are defined as linear polyesters of carbonic acid in which the carbonate groups recur in the polymer chain. In continuous production of the improved polyesters, it is preferred that the polycarbonate and catalyst be added to the process stream with mixing at a point to give 2 to 15 minutes reaction time under superatmospheric pressure before the polyester enters the last polycondensation reactor.

    • Process and apparatus for applying finish to yarn and confining finish are disclosed. The apparatus for applying finish features an applicator face which comprises the delivery area of a finish supply duct and the surface area of two primary arcs, one located on either side of the duct and curving in the general direction of yarn travel. The central angle subtended by each of the primary arcs ranges from about 2 to 9 degrees. The edge of each of the primary arcs remote from the duct terminates in a secondary arc which subtends a central angle of 30 to 60 degrees and with a radius length shorter than that of either primary arc. The apparatus for confining finish comprises a housing, plate and baffle(s). The housing substantially encloses a finish application device and has openings for yarn entrance and exit and for take-off of excess finish. The plate is mounted beneath the finish application device. The baffle(s) are disposed between the plate and the take-off opening. The plate and baffle(s) are oriented with respect to the housing such that any finish overflow and spray coming into contact therewith feed by gravity away from the traveling yarn to the take-off opening. The process comprises metering finish to an applicator face and simultaneously maintaining yarn in traveling contact with the entire length of the face and a portion of the edge thereof so that initial and last yarn-to-applicator contact is non-tangential to the applicator face.

    • A flexible hose assembly (10) transmits fluid between relatively movable components, such as a drive motor (16) secured to the main frame (14) of a vehicle (12) and pressurized fluid supply ports (13) resiliently supported on the main frame (14), in a constricted region where typical hose motions could result in chafing or cutting from contacts with adjacent structure. A flexed portion (39) of the hose (38) extends within a curved tubular rigid sleeve (47) which is fixed relative to one (16) of the fluid transmitting components (16, 13) and free of rigid attachment to the other (13). The diameter of the inside passage (51) of the sleeve (47) is greater than that of the hose (38) enabling limited necessary flexing while preventing more sizable and potentially damaging hose (38) movements. The curved hose portion (39) may have a radius of curvature smaller than the normal minimum bending radius as the sleeve (47) restrains kinking by preventing concentration of bending forces at one point on the hose (38).

    • A belted undercarriage assembly for a vehicle, such as a non-powered towed trailer, includes first and second endless belt assemblies, one positioned on each side of the vehicle, first and second wheel supporting frame assemblies associated respectively with the first and second belt assemblies, and a supporting axle connected to each of the frame assemblies and to the vehicle. Each of the frame assemblies includes first and second rectangular shaped tubes which are adapted to telescope together. A first threaded adjusting mechanism controls the telescopic relationship of the first and second tubes and a second threaded adjusting mechanism controls lateral movement of the first tube relative to the second tube. Providing proper belt tension and alignment of the belt on the guide wheels are important to efficient and economical operation of a belted undercarriage assembly. If proper tension is not maintained, or if the belt drifts to one side or the other, undesirable heat buildup and wear are produced. The subject belted undercarriage incorporates simple and economical apparatus and methods for controlling the tension and lateral movement of the belt.
