    • An improved process for the manufacture of polyester resin from the esterification of an aromatic acid with a glycol followed by polycondensation in the presence of a metal oxide catalyst in which spent glycol is removed during the course of the polycondensation reaction along with insolubles, large particulates, low molecular weight oligomers, metal oxide catalyst, cation impurities and anion impurities, and trace amounts of other impurities in which the temperature of the spent glycol is increased to maintain the monomer dissolved in solution while passing the spent glycol to a crossflow membrane filtration device with sufficient fluid velocity across the crossflow membrane filtration device to maintain turbulent flow. The glycol permeate is recycled to the esterification process while the concentrated insolubles are separated from the purged retentate.
    • 一种由芳族酸与二醇酯化制备聚酯树脂的改进方法,然后在金属氧化物催化剂存在下进行缩聚,其中在缩聚反应过程中除去废二醇以及不溶物,大颗粒, 低分子量低聚物,金属氧化物催化剂,阳离子杂质和阴离子杂质,以及痕量的其它杂质,其中消耗的二醇的温度升高以保持单体溶解在溶液中,同时将废二醇转化为交叉流过滤膜过滤装置, 足够的流体速度穿过横流膜过滤装置,以保持湍流。 将乙二醇渗透物再循环到酯化过程中,同时将浓缩的不溶物与清除的滞留物分离。

    • A kiln having a body with an internal chamber accessible via an opening which normally is closed by a closure that is movable. Lift apparatus effects movements of the closure between its closed and opened positions. The lift apparatus includes an arm which overlies the closure and is pivoted to a support independently of the kiln body for rotation about a second axis that is spaced a selected distance from the axis about which the closure rocks. The lift arm is connected to the closure by a pivot coupling which maintains the lift arm and the closure substantially parallel and uniformly spaced apart throughout the movements of the closure. The pivotal connection of the lift arm to the closure enables relative movement of the lift arm and the closure during movements thereof to avoid imposing appreciable stress on either the arm or the closure.
    • 一种具有主体的窑体,其具有通过开口可接近的内部腔室,该开口通常由可移动的封闭件封闭。 提升装置将闭合件的关闭位置和打开位置之间的运动进行影响。 提升装置包括臂,其覆盖在封闭件上并且独立于窑体枢转到支撑件,用于围绕围绕闭合岩石的轴线间隔开选定距离的第二轴线旋转。 提升臂通过枢转联接器连接到闭合件,枢转联接器在提升臂和闭合件的整个运动的整个过程中基本上保持平行且均匀间隔开。 提升臂与闭合件的枢转连接使得提升臂和闭合件在其运动期间能够相对运动,以避免在臂或闭合件上施加明显的应力。

    • A ceramic kiln of the kind having a body provided with an internal chamber to which access may be had via an opening which normally is closed by a closure that is movable from a closed position to an opened position. Lift apparatus is provided to effect movements of the closure between its closed and opened positions. The lift apparatus includes an arm which overlies the closure and is pivoted to a support independently of the kiln body for rotation about a second axis which is spaced a selected distance from the axis about which the closure rocks. The lift arm is connected to the closure by a pivot coupling which maintains the lift arm and the closure substantially parallel and uniformly spaced apart throughout the rocking movements of the closure. The pivotal connection of the lift arm to the closure enables bodily relative movement of the lift arm and the closure during rocking movements thereof in such manner as to avoid imposing appreciable stress on either the arm or the closure.
    • 一种具有主体的陶瓷窑,该主体设置有内部腔室,通过开口,该开口通常由可从关闭位置移动到打开位置的闭合器关闭。 提供提升装置以实现封闭件在其闭合位置和打开位置之间的运动。 提升装置包括臂,其覆盖在封闭件上并且独立于窑体枢转到支撑件,用于围绕围绕闭合岩石的轴线间隔开选定距离的第二轴线旋转。 提升臂通过枢转联接器连接到闭合件,该枢轴联接器在提升臂和闭合件的整个摇摆运动中基本平行且均匀间隔地保持提升臂和闭合件。 提升臂与闭合件的枢转连接使得提升臂和闭合件在其摆动运动期间能够相对运动,以避免在臂或闭合件上施加明显的应力。
