    • A dual gender electrical connector is made up of a "male" member, a "female" member, and a positioning means. The positioning means may be integral with either the male or female member, and/or a part of any shielding used. The male member is made up of a non-conductive support material of predetermined thickness in which electrically conductive electrical contacts are embedded in parallel. Short lengths of the electrical contacts are exposed on the rear end for connection to electrical conductors. Longer lengths of electrical contacts are exposed on the front end. The female member is made up of an electrically non-conductive support material of the basic form and often the same material as the male member, though not the same depth as the male member. Tubes having a length equal to approximately the depth of the female member support material are positioned within the support material so as to be capable of sliding over and in contact with the electrical contacts of the male member. When the female member is drawn forward by the positioning means, electrical contacts of the male member penetrate only a small portion of the tubes of the female member and provide a female plug. When the female member is positioned adjacent to the male member, the male electrical contacts extend through and beyond the tubes of the female member to create a male plug.
    • 双性电连接器由“男”构件，“女”构件和定位装置组成。 定位装置可以与阳构件或阴构件一体，和/或所使用的任何屏蔽件的一部分。 阳构件由预定厚度的非导电支撑材料构成，其中导电电触点并入嵌入。 电触点的短长度暴露在后端以连接到电导体。 较长的电触头暴露在前端。 阴构件由基本形式的非导电支撑材料构成，并且与阳构件通常具有相同的材料，尽管与阳构件的深度不同。 长度等于阴构件支撑材料的深度的管子定位在支撑材料内，以便能够滑动并与阳构件的电触点接触。 当阴构件被定位装置向前拉动时，阳构件的电接触仅穿过阴构件的管的一小部分并且提供阴插头。 当阴构件邻近阳构件定位时，阳电触头延伸穿过阴构件的管并且超过阴构件的管，以形成阳插头。

    • A fluid power unit has a cylinder in a housing, a piston slidable in the cylinder and dividing the cylinder into a retract side and an extend side, and a two-position control valve. The control valve has a spool and first and second pilots. The position of the spool is responsive to the first and second pilots. There is a retract poppet valve in the retract side of the cylinder, and an extend poppet valve in the extend side. The retract and extend poppet valves are biased to a closed position. The retract poppet valve is in a fluid path between the retract side and the control valve; the extend poppet valve is in a fluid path between the extend side and the control valve. The alternate movement of the piston in the cylinder alternately opens and closes the poppet valves, The circuit connects the poppet valves to the pilots and alternately applies and releases pressure to the pilots, causing the spool of the control valve to shift and apply inlet pressure to the piston on alternate sides. Thus the piston oscillates as long as inlet pressure is applied. All the fluid paths and the poppet valves are fluidly sealed inside the housing, so no gas is vented to the atmosphere.
    • 流体动力单元在壳体中具有气缸，可在气缸中滑动并将气缸分成回缩侧和延伸侧的活塞以及两位置控制阀。 控制阀具有线轴和第一和第二导频。 线轴的位置响应于第一和第二导频。 在气缸的缩回侧有一个缩回提升阀，在延伸侧有一个伸出的提升阀。 缩回和延伸提升阀被偏置到关闭位置。 缩回提升阀处于缩回侧和控制阀之间的流体路径中; 延伸提升阀处于延伸侧和控制阀之间的流体路径中。 活塞在气缸中的交替运动交替地打开和关闭提升阀。该回路将提升阀连接到飞行员，并交替地向飞行员施加和释放压力，使得控制阀的滑阀移动并将入口压力施加到 活塞在交替的侧面。 因此，只要施加入口压力，活塞就会振荡。 所有流体路径和提升阀都被流体地密封在壳体内，因此没有气体排放到大气中。

    • A chemical injection system has a pump and an actuator connected to the pump. The actuator further comprises a first sensor for sensing a deactivated state of the pump; a second sensor for sensing an activated state of the pump; a computer connected to the first and second sensors and the actuator; and an interface connected to the computer, to receive commands from, and to transmit data to, a control point. The computer further comprises a stored program. The stored program contains instructions to energize the actuator to cause the pump to dispense a pre-determined quantity of chemical and to verify that the pump has actually operated to dispense the pre-determined quantity of chemical.
    • 化学注射系统具有连接到泵的泵和致动器。 致动器还包括用于感测泵的停用状态的第一传感器; 用于感测所述泵的激活状态的第二传感器; 连接到第一和第二传感器和致动器的计算机; 以及连接到计算机的接口，用于从控制点接收命令和向控制点发送数据。 计算机还包括存储的程序。 存储的程序包含用于激励致动器以使泵分配预定量的化学品并且验证泵实际操作以分配预定量的化学品的指令。
