    • An identification labeling unit for applying identifying data to a sheet of X-ray film enclosed in a film cassette has data input means and a cassette insertion slot extending into the interior of its housing; a data display device, such as a vacuum fluorescent data display screen, defines an object plane inside the housing, and an optical system delivers an image of the data display screen focussed at an image plane within the cavity slot. When the X-ray film-enclosing cassette is fully inserted into the insertion slot, with a corner window hatchcover on the cassette being automatically opened by the cassette's insertion into the cavity slot, the corner of the X-ray film receives the focussed labeling data image from the optical system.
    • 用于将识别数据应用于封装在胶片暗盒中的X射线胶片的识别标签单元具有延伸到其外壳内部的数据输入装置和盒插入槽; 诸如真空荧光数据显示屏幕的数据显示设备限定了壳体内的物体平面,并且光学系统传送聚焦在空腔内的图像平面上的数据显示屏的图像。 当X射线胶片包装盒完全插入插槽中时,磁带盒上的角窗口舱盖将被磁带盒插入腔槽中而自动打开,X光胶片的角部接收聚焦的标签数据 来自光学系统的图像。

    • A combination directional gyro and navigation radio indicator instrument for use in aircraft which provides a display of compass card, selected course pointer, course deviation indicator, to-from indicator, and glide slope indicator in a unique presentation. The compass card is directly driven by the directional gyro, and the selected course pointer normally rotates with the compass card when it rotates, but can be de-clutched for selection of a new course. The selected course signal is obtained by attenuating, amplifying, and phase shifting the reference signal from a navigation radio such that it can be sent to the rotor of a control transformer which is geared to the compass card. The resulting stator signal is then amplified and sent to the rotor of a differential resolver which is geared to the course selector pointer. The control transformer and the differential transformer rotors turn in opposite directions such that the reference signal does not change when the compass card and the course selector pointer move together, but does change when the course selector is de-clutched and moves independently of the compass card. The resulting signal from the stator of the differential transformer is therefore an electrical representation of the selected course. This signal is then sent back to the navigation radio where it is compared to the signal representing the actual course of the aircraft that is received from a stationary navigation radio transmitter (VORTAC).
    • 用于飞机中的组合定向陀螺仪和导航无线电指示仪,其在独特的演示中提供指南针卡,选择的路线指针,航向偏差指示器,从指示器和滑翔坡度指示器的显示。 指南针由定向陀螺仪直接驱动,所选课程指针在旋转时通常与罗盘卡一起旋转,但可以解除选择新课程。 所选择的路线信号是通过衰减,放大和相移来自导航无线电装置的参考信号而获得的,使得其可被发送到与罗盘卡相对应的控制变压器的转子。 然后,所得到的定子信号被放大并发送到与行程选择器指针相对应的差分解算器的转子。 控制变压器和差动变压器转子相反方向转动,使得当指南针卡和踏板选择器指针一起移动时,参考信号不会改变,但是当课程选择器被去离合并且独立于罗盘时移动时会改变参考信号 。 因此,来自差动变压器的定子的结果信号是所选路线的电表示。 然后,该信号被发送回导航无线电,在那里将其与表示从固定导航无线电发射机(VORTAC)接收的飞行器的实际航向的信号进行比较。
