摘要： A current feedback switch for the charging supply of a pulse forming network (PFN) is provided with regenerative feedback through a transformer T2 and a control transistor Q2 in order that base current be more efficiently provided to drive a main switching transistor Q1 to saturation. Turning-off the main switching transistor Q1 is facilitated by the transistor Q2 in series with the feedback transformer T2. In that manner current is more efficiently turned on and off to charge the PFN.

摘要： There is disclosed a liquid crystal digital reticle comprising a liquid crystal cell formed by two transparent plates of a material such as glass which are separated by a spacer around their edges and confine a liquid crystal material between them. The inside surface of each plate is provided with a plurality of transparent conductors laid down in an incremental pattern such as plurality of closely spaced parallel lines, the conductors on one plate extending horizontally and the conductors on the other plate extending vertically. The cell is positioned at a focal plane of the objective lens of a telescope or other optical sighting device. With no voltage applied, the glass plates and the liquid crystal material between them are transparent. When a voltage is applied between a switch selectable one of the vertical conductors and a switch selectable one of the horizontal conductors, not only the crystal material in the volume defined by the projective intersection points of the two conductors, but also portions of the material adjacent to such intersections on the entire length of each of the two selected conductors is activated to the dynamic scattering mode. The light scattering effect forms apparent lines in a cross-hair pattern against either light or dark backgrounds. The intersection point of these lines can be moved at will by appropriate matrix addressing techniques to select one horizontal and one vertical conductor. The mechanism by which energization of only two non-aligned conductors causes scattering along the length of both conductors is not fully understood but is believed to be due to a crosscoupling or ''''cross-talk'''' phenomenon.
摘要翻译：公开了一种液晶数字掩模版，其包括由诸如玻璃的材料的两个透明板形成的液晶单元，所述透明板由间隔件围绕它们的边缘分开，并在其间限制液晶材料。每个板的内表面设置有多个透明导体，其以诸如多个紧密间隔的平行线的增量图案布置，一个板上的导体水平延伸，另一个板上的导体垂直延伸。单元位于望远镜或其他光学瞄准装置的物镜的焦平面上。在没有施加电压的情况下，它们之间的玻璃板和液晶材料是透明的。当在可选择的一个竖直导体中的电压和可选择的一个水平导体之间施加电压时，不仅由两个导体的投影交叉点限定的体积中的晶体材料，而且材料的相邻部分相邻在两个所选择的导体中的每一个的整个长度上的这些交点被激活到动态散射模式。光散射效应在相对于浅色或深色背景的交叉图案中形成明显的线条。这些线的交点可以通过适当的矩阵寻址技术随意移动，以选择一个水平和一个垂直导体。只有两个不对准的导体的激励导致沿着两个导体的长度的散射的机制尚未完全清楚，但被认为是由于交叉耦合或“串扰”现象。

摘要： The inductor of a pulse forming network comprising a storage capacitor and inductor is provided by the secondary winding of a series-connected trigger transformer. Electromagnetic radiation is minimized while the stored energy is discharged through a flash lamp with a current waveform determined by the inductance of the secondary winding and the capacitance of the storage capacitor. The waveform is maintained at a desired level determined by the design of the secondary windings on cores of high saturation material. The secondary windings are tightly wound to minimize radiation from the sides of the cores, and the ends of the cores are closed by high permeability, high saturation density material to minimize radiation of the ends of the cores. The cap which prevents saturation of the main transformer core is filled with high permeability, low saturation density material to facilitate use as a trigger transformer.

摘要： A range gate circuit including two serially connected flip-flops for producing a pulse train output signal derived from a clock pulse signal during the interval of time between gate signals that correspond to transmitted range pulse signals and reflected energy signals. A plurality of the individual gate means are further connected in parallel circuit relationship in which each of the gate means is connected to another gate means so that the pulse train from each of the gate means is initiated simultaneously by the gate signals corresponding to transmitted range pulse signals and are sequentially discontinued by sequentially received reflected energy signals received from a plurality of targets whereby the range of the targets can be determined from the pulse counts of the pulse trains.

摘要： A transformer charging system that provides a highly efficient operation and that substantially eliminates switching transients. The high voltage or secondary winding of the transformer as well as the primary winding in some arrangements, is divided into segments which are isolated from each other by unidirectional current conductive devices such as diodes. For charging a load coupled to the secondary winding, current pulses are repetitively applied to the primary winding from the power source with the flyback voltage resulting from the pulse terminations causing current to flow through the diodes. The diodes allow the stray capacitance associated with each segment to initially charge but prevent them from discharging between the repetitive operations, which would cause additional flow of primary current and dissipation losses.
