摘要： A connecting member comprises a rod-shaped body having a head and/or thread on the outer periphery for integrally connecting a plurality of members and a containing hole opened at one end thereof and extended longitudinally, a rod disposed in the hole so as to fix at its inner end to the inner end of the hole, a transmissive window fixed to the opening of the hole, and a fluid holding member holding a colored fluid and pressed by the open side end of the rod on the window. When a longitudinal strain developed in the body the rod release the holding member from under pressure so that colored fluid covers the open side end of the rod.

摘要： A device for indicating when a lug nut has come loose on an automobile wheel. In one embodiment, the device operates by detecting relative movement between the lug nut and the axle stud on which it is mounted. In a second embodiment, the detected relative movement is between the lug nut and the wheel itself. In the preferred embodiment, the device has a first member with an open-ended channel and second and third members slideably received in it. The second member operates in cooperation with the sides of the channel and one of the springs to hold the third member in a retracted or cocked position when the lug nut is in its preferred, tight position against the wheel. Thereafter, should the lug nut come loose and move relative to the stud, the second member will follow or move under the force of its spring outwardly to maintain contact with the free end of the stud. In doing so, the third or indicator member is released to move in the opposite direction under the force of its spring to protrude beyond the outer surface of the lug nut where it can be easily and quickly seen or felt by hand. In the second embodiment, the second or follower member abuts the wheel itself rather than the free end of the stud but otherwise operates in the same manner.
摘要翻译：用于指示凸耳螺母何时在汽车轮上松动的装置。在一个实施例中，该装置通过检测在其所安装的凸耳螺母和轴螺柱之间的相对运动来操作。在第二实施例中，检测到的相对运动位于凸耳螺母和车轮本身之间。在优选实施例中，该装置具有第一构件，其具有开放式通道，第二和第三构件可滑动地容纳在其中。第二构件与通道的侧面和弹簧中的一个协作操作，以在凸耳螺母处于其相对于车轮的优选紧密位置时将第三构件保持在缩回位置。此后，如果凸耳螺母松动并相对于螺栓移动，则第二构件将在其弹簧的力作用下向后移动或保持与柱塞自由端接触。在这样做时，第三或指示件被释放以在其弹簧的作用力下沿相反方向移动，以突出超过凸耳螺母的外表面，在那里可以容易地并且快速地看到或感觉到手。在第二实施例中，第二或从动构件抵靠车轮本身而不是螺柱的自由端，但是以相同的方式操作。

摘要： Fasteners such as mine bolts are provided with tension indicators to directly read tension in the shank of the bolt. The preferred tension indicators comprise an elongated pin disposed in a bore formed in the bolt and connected at the bottom of the bore to the bolt shank to be tensioned thereby. The tension indicator further comprises a cross bar attached to the other end of the pin and extending laterally into engagement with another portion of the bolt, such as the head of the bolt, to be bent upon tensioning of the pin. Preferably, a photoelastic member is attached to the cross bar and bending stresses in the cross bar are manifested in the photoelastic member in the form of photoelastic fringes for reading by a reflection polariscope.

摘要： A strain indicator of the type wherein a change in length of a strain member produces a change in color of a visual indicator. An indicator area and a light-absorbing indicator fluid are encapsulated in a member that also includes a window. The capsule is fastened to the strain member with an adhesive. A change in length of the strain member causes the indicator area to become separated from the window with the result that light-absorbing indicator fluid is caused to flow between the indicator area and the window. The method of the invention comprises method steps of manufacturing subassemblies of the strain indicator as well as the method steps leading to complete assembly of the indicator.

摘要： A power supply and signal transmitting device for a sensing bolt and sensing bolt device is provided. The power supply and signal transmitting device, which is applied to the sensing bolt including a first contact set, includes a cap module and a supply module. The cap module caps one end of the sensing bolt and includes a cap circuit board module. A second contact set of the cap circuit board module contacts the first contact set for electrically connecting the sensing bolt. The supply module is interposed into the cap module for supplying an external power to the sensing bolt or accessing the io data stored in the sensing bolt by electrically connecting a third contact set of the cap circuit board module with a fourth contact set of the supply module. Thereby, the power duration of the sensing bolt may be improved.

摘要： In a method for extending a threaded bolt by tensioning a threaded end section thereof with a tensioning device, an exchange socket of the tensioning device is screwed onto the threaded end section and a first pin end of a pin slidable in the exchange socket is supported against an end of the threaded end section so that the pin moves in longitudinal direction as the exchange socket is screwed on. A sensor senses a longitudinal position of the pin relative to the exchange socket. An evaluation and control unit compares whether the detected longitudinal position of the pin relative to the exchange socket corresponds to a predefined minimum position value indicating sufficient thread engagement length. When the detected longitudinal position corresponds to the predefined minimum position value, the evaluation and control unit acts on the hydraulic supply to tension the threaded end section of the threaded bolt.
