    • Apparatus 11 and 13 for interfacing two AC sources with two AC loads 17a 17b in the form of solenoid operated valves over a single conductor 25, with a return conductor 19 in an irrigation system is disclosed. The apparatus has an encoder circuit 11 with two inputs 21a 21b for connection to the two AC sources, and an output 23 for connection to the single conductor 25, and a decoder circuit 13 having an input 27 for connection to the conductor 25, and two outputs 29a 29b for connection to loads 17a 17b respectively. When the first input 21a is powered, the first load 17a will be switched on, and when the second input 21b is powered, the second load 17b will be switched on. The decoder portion 13 incorporates switching circuits 43a 43b, interfaced with turn on delay timers 45a 45b respectively, to delay operating the loads at switch on, and turn-off delay timers 47a 47b to hold the loads on after switch off.
    • 公开了用于将两个AC源与在单个导体25上的电磁阀形式的两个AC负载17a 17b接口的装置11和13,其中在灌溉系统中具有回路导体19。 该装置具有编码器电路11,其具有用于连接到两个AC源的两个输入端21a 21b和用于连接到单个导体25的输出23,以及具有用于连接到导体25的输入端27的解码器电路13,以及两个 输出端29a 29b分别连接到负载17a 17b。 当第一输入21a被供电时,第一负载17a将被接通,并且当第二输入21b被供电时,第二负载17b将被接通。 解码器部分13包括分别与接通延迟定时器45a 45b接口的开关电路43a 43b,以在接通时延迟操作负载,以及关断延迟定时器47a 47b以在关断之后保持负载。

    • An aquatic device (10) for providing manoeuvrability to a user (11) moving in water. The aquatic device (10) may be propelled through the water in any appropriate way, such as by being towed through the water or propelled through the water by the user (11). The aquatic device (10) comprises a handle means (20) adapted to be grasped by the user (11) with arms extending forwardly, and two fins (21, 22) movable one with respect of one to the other to manoeuvre the aquatic device. The aquatic device (10) can be manoeuvred through movement of the fins (21, 22) to provide directional control or variation to the orientation of the aquatic device. The directional control may include both steering and depth control. The handle means (20) are operably connected to the two fins (21, 22) whereby the user can manually control movement of the fins one with respect to the other.
    • 一种用于向在水中移动的使用者(11)提供机动性的水上装置(10)。 水生装置(10)可以以任何适当的方式通过水被推进,例如通过水被牵引或者由使用者(11)通过水推进。 水上装置(10)包括一个手柄装置(20),该手柄装置(20)适于被使用者(11)抓握,臂部向前延伸,以及两个翅片(21,22),它们可相对于另一个相互移动,以操纵水上装置 。 可以通过翼片(21,22)的移动来操纵水上装置(10),以提供对水生装置的取向的方向控制或变化。 方向控制可以包括转向和深度控制。 手柄装置(20)可操作地连接到两个翅片(21,22),由此用户可以手动地控制翅片相对于另一个的运动。
