    • A multi-vinylsulfone containing molecule is described herein. The multi-vinylsulfone containing molecule can be formed by dissolving a water soluble polymer containing a hydroxyl group in an aqueous solution to form a polymer solution; adding a molecule containing two vinylsulfone groups to the polymer solution; and forming a modified polymer by controlling a number of the vinylsulfone groups that are added to the polymer. A hydrogel is also described herein that can include the multi-vinylsulfone containing molecule and a multi-thiol containing molecule. The hydrogel can be formed from an aqueous solution that includes the multi-vinylsulfone containing molecule and the multi-thiol containing molecule by undergoing gelatation upon delivery to a site in the body. Also described is a drug delivery system that employs the hydrogel.
    • 本文描述了含有多乙烯基砜的分子。 含有多乙烯基砜的分子可以通过将含有羟基的水溶性聚合物溶解在水溶液中形成聚合物溶液而形成; 向聚合物溶液中加入含有乙烯基砜基团的分子; 以及通过控制添加到聚合物中的数量的乙烯基砜基来形成改性聚合物。 本文还描述了可以包括含有多乙烯基砜的分子和含多硫醇的分子的水凝胶。 水凝胶可以由含有多乙烯基砜的分子和含多硫醇的分子的水溶液形成,通过在递送到体内的部位时经历凝胶化。 还描述了采用水凝胶的药物递送系统。

    • A circuit breaker, comprising a locking device, a secondary cover and a tripbar operatively associated with the locking device. The locking device comprises a lock assembly and a piston assembly operatively coupled with the lock assembly. A through hole for the lock assembly is provided in the secondary cover. The lock assembly has a locked position and an unlocked position, and the piston assembly has a work position and a rest position respectively corresponding to the locked and unlocked positions. The piston assembly is configured to prevent the tripbar from moving to a relatch position when it is in the work position, such that the circuit breaker cannot be turned on. The locking device is configured to be installed on the circuit breaker through the through hole.
    • 一种断路器,包括锁定装置,辅助盖和与所述锁定装置可操作地相关联的跳闸。 锁定装置包括锁定组件和与锁定组件可操作地联接的活塞组件。 用于锁组件的通孔设置在次盖中。 锁定组件具有锁定位置和解锁位置,并且活塞组件具有分别对应于锁定和解锁位置的工作位置和静止位置。 活塞组件被构造成防止跳闸在工作位置时移动到重合位置,使得断路器不能被接通。 锁定装置构造成通过通孔安装在断路器上。
