摘要： A mortar barrel is fitted with a plane mirror which reflects a first imagen a viewing screen positioned in front of the mortar. A floating mirror which remains level with the ground plane is mounted to the barrel and reflects a second image on the viewing screen. Adjustment of the mortar is made for superposition of both images. After repeated firings, motar cant movement may be detected by the relative displacement of the images which requires readjustment.
摘要翻译：砂浆桶配有一个平面镜，它将第一个图像反映在位于迫击炮前面的观察屏幕上。与地平面保持平齐的浮动镜安装在枪管上并在观察屏幕上反射第二个图像。调整砂浆是为了叠加这两幅图像。反复发射后，可能通过需要重新调整的图像的相对位移来检测到运动不稳定。

摘要： The invention is directed to a security device which detects tampering with secured closure. A fiber optic bundle is looped through a closure and secured at opposite ends of the bundle to a collar. After installation, light is passed through the fiber optics and they generate a particular pattern at a viewing end of the collar. If there is any tampering with the enclosure, the individual fiber optics will be disturbed or cut. Subsequent viewing of the fiber optics will generate a different viewing pattern indicating that tampering has occurred.
摘要翻译：本发明涉及一种安全装置，其检测篡改安全闭合件。光纤束环通过封闭件，并将其固定在套管的相对端部处。安装后，光通过光纤，并且在轴环的观察端产生特定的图案。如果外壳有任何篡改，单个光纤将受到干扰或切断。随后观察光纤将产生指示发生篡改的不同观察模式。

摘要： The invention is directed to a security device which detects tampering with secured closure. A fiber optic bundle is looped through a closure and secured at opposite ends of the bundle to a snap-together connector. An intermediate length of the fiber optic bundle surrounds the snap-together connector preventing access to its locking mechanism unless fibers are severed. After installation, light is passed through the fiber optics and a particular pattern is generated at a viewing end of the connector. Tampering with the closure will cause individual fiber optics to be disturbed or cut so that subsequent viewing of the fiber optics will generate a different viewing pattern than originally observed.
摘要翻译：本发明涉及一种安全装置，其检测篡改安全闭合件。光纤束环通过封闭件并且在束的相对端固定到卡扣连接器。光纤束的中间长度包围卡扣连接器，防止接触其锁定机构，除非纤维被切断。安装后，光通过光纤，在连接器的观察端产生特定的图案。使用闭合件篡改将导致单个光纤被干扰或切割，以便随后观察光纤将产生与原始观察不同的观看模式。
