    • A thermostatic switch has a housing and a temperature responsive bimetallic disc located in the housing and responsive to a predetermined temperature for exerting a flexing action. A fixed contact member is located in the cavity along with a movable contact member which is biased and movable between a switch-closed position in which it makes electrical contact with the fixed contact member and a switch-open position in which it is spaced from the fixed contact member. An actuating member is located in the housing, and is responsive to flexing movement of the disc for moving the movable contact member from the switch-closed position to the switch-open position. A hook portion is mounted within the cavity of the housing, the hook portion engaging an arm portion of the movable contact member upon the movement of the movable contact member to its switch-open position and entering an opening of the arm portion for retaining and maintaining the movable contact member in its switch open position.
    • 恒温开关具有位于壳体中的壳体和温度响应双金属盘,并且响应于预定温度以施加弯曲动作。 固定接触构件与可动接触构件一起位于空腔中,可动接触构件被偏置并可在其与固定接触构件电接触的开关闭合位置和与该固定接触构件电气接触的开关位置之间移动 固定接触件。 致动构件位于壳体中,并且响应于盘的挠曲运动,用于将可动接触构件从开关关闭位置移动到开关打开位置。 钩部分安装在壳体的空腔内,当活动触头构件移动到其开关位置并进入臂部分的开口以保持和保持时,钩部分接合可动触头构件的臂部分 可动接触构件处于其开关打开位置。

    • A surgical instrument is provided that comprises two coaxial tubes mounted for relative telescoping motion, and a unitary jaw piece of springy material affixed to the remote end of one of said tubes and having two jaws normally biased apart to a selected open position. The other one of said tubes is movable longitudinally relative to said one tube so that the forward end of the said other tube forces the jaws to close. The jaw piece includes a body section joined to the two jaws by spring leaves having a selected configuration, with the result that when the jaws are moved to closed position, the forward ends of the jaws engage one another before there is any engagement between the rear ends of the jaws. The jaw piece also has an opening permitting introduction of an ancillary device to a position permitting communication with the space between the jaws.
    • 提供了一种手术器械,其包括安装用于相对伸缩运动的两个同轴管,以及固定到所述管中的一个的远端的弹性材料的整体颚片,并且具有通常被偏压到选定的打开位置的两个钳口。 所述管中的另一个相对于所述一个管可纵向移动,使得所述另一个管的前端迫使钳口关闭。 颚件包括通过具有所选构造的弹簧叶片连接到两个钳口的主体部分,结果是当钳口移动到关闭位置时,钳口的前端在后部之间存在任何接合之前彼此接合 颚的末端。 颚板还具有允许将辅助装置引入允许与夹爪之间的空间通信的位置的开口。
