    Abstract: A method and apparatus for automatically sensing and for maintaining registration of each of the color cylinders utilized in a multi-color printing press is disclosed. Predetermined register marks are printed in the non-image areas on the sheet to be printed. Typically, in a four-color printing process, the black image is used as a reference, and registration of the other three image colors is achieved relative to the black image. Accordingly, a register mark for each process color is printed in the same location as a corresponding black reference register mark. The reference register marks are configured such that the average reflectance of the printed overlay will change as the registration of the color image changes with respect to the black image. In general, the configuration of the register marks for the black and color images differs. The reflectance of each printed overlay is measured on the printing press, while the sheet is moving. One type of sensor that can be used for this measurement is an on-press densitometer, or more generally, a reflectometer. If desired, the reflectance information obtained thereby can be converted to a registration error signal and used to achieve automatic, closed-loop control of the position of each of the color cylinders.

    Abstract translation: 公开了一种用于自动感测并保持在多色印刷机中使用的每个彩色墨盒的配准的方法和设备。 在要打印的纸张上的非图像区域中打印预定的对准标记。 通常，在四色打印处理中，黑色图像被用作参考，并且相对于黑色图像实现其他三种图像颜色的配准。 因此，每个处理颜色的对准标记被打印在与相应的黑色参考对准标记相同的位置。 参考对准标记被配置为使得随着彩色图像的配准相对于黑色图像改变，打印的叠加层的平均反射率将改变。 通常，黑色和彩色图像的对准标记的配置不同。 当印张移动时，在印刷机上测量每个印刷的覆盖层的反射率。 可以用于该测量的一种类型的传感器是按压光密度计，或更一般地，反射计。 如果需要，由此获得的反射率信息可以被转换为对准误差信号，并用于实现每个彩色柱体的位置的自动闭环控制。

    Abstract: In a power supply system for a variable reluctance motor, each phase winding (a, b) of the motor is connectible across a pair of supply rails by first (GTO a , GTO b ) and second (T a T e ) switch means located respectively between the first supply rail and the winding and between the winding and the second supply rail. The first switch means (GTO., GTO b ) is a fast switch-off device such as a gate tum-off thyristor or a transistor, while the second switch means (T a , T b ) is a slow turn-off device, such as a thyristor suitable for application to a line-commutation situation. In a two-phase configuration, where the second switch means is a thyristor, force- commutation of the second switch means may be achieved by means of a suitable capacitor (C c ) interconnection between the thyristors switching the respective phases.

    Abstract: A system for determining range and orientation of distant objects, such as a ship, is claimed. By utilizing split imaging the observed height on a video monitor can be accurately determined despite movements of the image on the monitor. The observed ship can be visually identified and the true height determined from reference source. A better comparison of data indicating the true height compared to observed height permits calculation of the rangeto the target ship. Split imaging can also be utilized to determine the observed length of the ship so that observed height and length data can be compared to the true height and length of the target ship to determine orientation of the target ship relative to the observed.
