摘要： A device for rapidly moving mechanically actuated devices, such as switches and valves with the capability of sub-millisecond response times being achievable with moving masses exceeding one kilogram. Response times approaching that of explosively actuated devices are obtained while retaining the repetitive cycling capability of non-explosively operated devices. Electrical energy stored in a capacitor pulses through electrodes and closed and open ends of a capillary tube to rapidly heat a gas and raise its pressure to a thousand atmospheres or more. The high pressure gas acts on a piston, accelerating it for a short distance before the pressure is vented around the piston to quickly reduce the drive force. The moving piston is brought to a stop by a hydraulic damping device. A reset device resets the piston, the capillary is refilled with working gas, and the capacitor is charged fro the next operation.

摘要： A surface wave communication system is disclosed which provides a communication link between moving objects via a single conductor transmission line. The system includes a wire dispenser for storing and paying out transmission line as needed, and an RF coupling device for initiating and intercepting a surface wave bound to the transmission line.

摘要： A high voltage switch contact structure capable of interrupting high voltage, high current AC and DC circuits. The contact structure confines the arc created when contacts open to the thin area between two insulating surfaces in intimate contact. This forces the arc into the shape of a thin sheet which loses heat energy far more rapidly than an arc column having a circular cross-section. These high heat losses require a dramatic increase in the voltage required to maintain the arc, thus extinguishing it when the required voltage exceeds the available voltage. The arc extinguishing process with this invention is not dependent on the occurrence of a current zero crossing and, consequently, is capable of rapidly interrupting both AC and DC circuits. The contact structure achieves its high performance without the use of sulfur hexafluoride.
摘要翻译：高压开关触点结构，能够中断高压，大电流交流和直流电路。接触结构限制了当触点在两个绝缘表面之间的薄区域内紧密接触时产生的电弧。这迫使电弧变成与具有圆形横截面的弧柱相比更快地损失热能的薄片的形状。这些高热损失需要显着增加维持电弧所需的电压，从而在所需电压超过可用电压时熄灭它。本发明的灭弧方法不依赖于电流过零的发生，因此能够快速中断交流和直流电路。接触结构在不使用六氟化硫的情况下实现其高性能。

摘要： A high voltage pulse generator provides a short, fast rise, high voltage pulse from a very low impedance suitable for initiating high energy electrical discharges in liquids and high pressure gases. Its low impedance allows extremely high currents from external energy storage capacitors to be conducted through the invention once the invention has initiated an arc. Its fast rise time is suitable for initiating multiple arcs or even sheet surface discharges in high pressure gasses under suitable conditions.
