    • A casement window assembly has a sash window pivotally connected to a window frame. A window operator has a housing connected to the frame, including an upper and lower piece connected together. The housing has an offset countersink hole receiving a fastener. A spindle extends into the housing and has a groove therein. An arm is operably connected to the spindle and to the sash window to open and close the sash window. A resilient seal member is received within the groove in the spindle. A first gasket is positioned between the upper piece and the lower piece of the housing. A second gasket is positioned between the housing and the window frame. When the fastener is driven into the countersink hole, the housing is forced in a generally horizontal direction to compress the second gasket between the housing and the window frame.
    • 平开窗组件具有枢转地连接到窗框的窗框窗口。 窗户操作者具有连接到框架的壳体,包括连接在一起的上部和下部件。 壳体具有接收紧固件的偏移锪孔。 心轴延伸到壳体中并且在其中具有凹槽。 臂可操作地连接到主轴和窗框窗口以打开和关闭窗扇。 弹性密封件容纳在主轴的槽内。 第一垫圈位于壳体的上部件和下部件之间。 第二垫圈位于壳体和窗框之间。 当紧固件被驱动到埋头孔中时,壳体被迫在大致水平的方向上以压缩壳体和窗框之间的第二垫圈。

    • Processes for conjugating proteins with polyethylene glycol are disclosed. The disclosed processes provide modified proteins having little or no decrease in their activity and include the steps of deleting at least one amino acid residue on the protein, replacing the at least one amino acid residue with an amino acid residue that does not react with polyethylene glycol, and contacting the protein with polyethylene glycol under conditions sufficient to conjugate the polyethylene glycol to the protein. This advantageous retention of a desired protein activity is attributed to the availability of one or more protein binding sites which is unaltered in the conjugation process and thus remains free to interact with a binding partner ligand or cognate subsequent to the conjugation process.
    • 公开了将蛋白质与聚乙二醇缀合的方法。 所公开的方法提供了其活性几乎没有或没有降低的修饰的蛋白质,包括删除蛋白质上的至少一个氨基酸残基的步骤,用不与聚乙二醇反应的氨基酸残基取代至少一个氨基酸残基 并在足以将聚乙二醇与蛋白质缀合的条件下使蛋白与聚乙二醇接触。 所需蛋白质活性的这种有利的保留归因于在缀合过程中未改变的一个或多个蛋白质结合位点的可用性,因此在缀合过程之后保持与结合配偶体配体或同源物相互作用。
