    摘要： A liquid piston system includes a liquid piston compressor/expander assembly and a drive mechanism. The liquid piston compressor/expander assembly includes a reciprocating cylinder coupled with the drive mechanism and a static liquid piston received in the cylinder cavity. The static liquid piston includes a piston face configured to carry liquid piston fluid. The reciprocating cylinder is configured to move relative to the static liquid piston between contracted and expanded positions. In a compressor, at the expanded position the cylinder head is withdrawn from liquid piston fluid and the cylinder cavity is filled with the compressible fluid. In the contracted position the cylinder head of the reciprocating cylinder is near the liquid piston fluid and the compressible fluid is compressed. With an expander, in the contracted position the compressible fluid is introduced to the cylinder cavity and the expanding compressible fluid moves the reciprocating cylinder to the expanded position.

    摘要翻译： 液体活塞系统包括液体活塞式压缩机/膨胀机组件和驱动机构。 液体活塞式压缩机/膨胀器组件包括与驱动机构联接的往复式气缸和容纳在气缸腔中的静态液体活塞。 静态液体活塞包括构造成承载液体活塞流体的活塞面。 往复式气缸被构造成在收缩和膨胀位置之间相对于静态液体活塞移动。 在压缩机中，在膨胀位置，气缸盖从液体活塞流体中取出，并且气缸腔被可压缩流体填充。 在收缩位置，往复式气缸的气缸盖靠近液体活塞流体，可压缩流体被压缩。 在膨胀器中，在收缩位置，可压缩流体被引入到气缸腔中，并且膨胀的可压缩流体将往复式气缸移动到扩展位置。

    摘要： A duct is provided having a flattened portion containing a liquid slug of gallium, and a magnetic field is passed through the gallium while an alternating current is also passed through the gallium to produce back and forth motion of the liquid gallium slug in step with the alternating current, enabling compression of working fluid within the duct.

    摘要： A rigid waterproof structure built on the ocean floor near a shore is completely enclosed. Guides are provided to direct the waves or swells from the ocean to an inlet opening which is completely covered, by a free-hanging heavy gate which latter is opened when the waves or swells move toward the shore thereby introducing water into the dome-like structure and displacing the air therein, thus compressing it. The air is forced out through check valves and thus compressed is conducted to a storage tank for the compressed air. Air intakes are provided which are closed when the air is compressed in the structure and are opened when the water escapes from the structure. As the waves are receding from the shore the free-hanging gate is drawn over the inlet opening and closes the same, and a device, in this form cables over pulleys connected to the free-hanging gate and to gates covering respective outlets, pulls the gates open thereby letting the water escape from the structure behind and outside the guide walls instead of the same way it entered and thereby not interfering with the next incoming swell or wave.

    摘要翻译： 建在靠近岸边的海底的刚性防水结构完全封闭。 引导件用于将波浪或波浪从海洋引导到完全覆盖的入口开口，该入口开口由自由悬挂的重型闸门，后者当波浪或波浪向岸边移动时打开，从而将水引入到圆顶状结构中 并使其中的空气移位，从而压缩它。 空气通过止回阀被迫排出，因此被压缩的空气被传导到用于压缩空气的储罐中。 提供进气口，当空气在结构中被压缩时关闭，并且当水从结构中逸出时打开。 随着波浪从岸边退出，自由悬挂的门被拉过入口并关闭，并且以这种形式的装置电缆连接到连接到自由悬挂门的滑轮和覆盖相应出口的门，拉动 门打开，从而使水从引导壁后面和外部排出，而不是与进入的方式相同，从而不会干扰下一个进入的隆起或波浪。
