    • An addressable event display and control system for use with a clock controlled programmable memory employs an array of LED's as event designators each of which signifies, when energized, a programmed event in the memory. A bank of seven dual LED's, which is coupled to the memory, is selectively energizable to visually indicate a particular day of the week. When a particular day is selected, the array of designators for that day can be interrogated to determine which of the designators have been programmed for the particular day. Thereafter, a desired one of the designators can be selected to afford review of the program content of the event associated with that designator. The selected event designator is identified by a blinking visual signal. The time of day, a channel and a recording duration time are selectable to identify a particular event and that information is programmable into the memory for subsequent retrieval to control a video frequency recorder in accordance with such information.

    • In a raster-centering circuit for a TV set or other cathode ray tube system, various voltage divider configurations including adjustable resistances are used to establish adjustment DC levels at one or both ends of a vertical deflection coil. If these adjustable resistances are adjusted to apply a potential difference across the deflection coil, the result is a constant centering current flowing through the coil to maintain a steady-state magnetic bias field for vertical centering of the electron beam. In one configuration the sweep amplifier itself is part of the DC centering current path. All of the adjustable resistances are ganged in aiding relationship so far as their effect on the direction of beam centering is concerned.

    • In a color projection TV system using three cathode ray tubes (one for each of the primary colors green, red and blue), the vertical deflection coils of all three CRT's are capacitively coupled in a series string configuration so that they can be driven by a common amplifier. The capacitors provide AC coupling at the sweep frequency, but maintain DC isolation between the deflection coils. For raster-centering purposes various voltage divider configurations including adjustable resistances are used to establish adjustable DC levels at different ends of each coil. If any of these adjustable resistances are adjusted to apply a potential difference across any of the deflection coils, the result is a constant centering current flowing through each of those coils to maintain steady-state magnetic bias fields for vertical centering of the electron beams. In some configurations the sweep amplifier itself is part of the DC centering current path. All of the adjustable resistances associated with a given deflection coil are ganged in aiding relationship so far as their effect on the direction of beam centering is concerned, but the adjustable resistances for each CRT are adjustable independently of any other CRT to facilitate proper fusion of the three primary color images.
    • 在使用三个阴极射线管(每个原色为绿色,红色和蓝色一个)的彩色投影电视系统中,所有三个CRT的垂直偏转线圈以串联配置电容耦合,使得它们可以由 普通放大器。 电容器在扫频频率下提供交流耦合,但保持偏转线圈之间的直流隔离。 对于以光栅为中心的目的,可以使用包括可调电阻的各种分压器配置来在每个线圈的不同端部建立可调节的直流电平。 如果调整这些可调节电阻中的任何一个以在任何偏转线圈上施加电位差,结果是流过每个线圈中的每一个的恒定的定心电流,以保持用于电子束垂直居中的稳态磁偏置场。 在一些配置中,扫频放大器本身是直流定心电流路径的一部分。 与给定的偏转线圈相关联的所有可调节的电阻器,只要它们对光束定中心的方向的影响就被组合在辅助关系中,但是每个CRT的可调节电阻可以独立于任何其他CRT来调节,以促进 三原色图像。
