摘要： A fault detection and clearance system for paralleled electrically similar power transmission lines wherein at each end of the line matched separate directional relays respectively connected to trip associated fault clearance circuit breakers have polarized windings and operate windings. The polarized windings are energized by an alternating current proportional to the summation while the operate windings are energized by an alternating current proportional to the difference (phase considered) of fault currents going into the breakers in both lines at the adjacent end in the event of a fault.

摘要： A system for heating and cooling a building is disclosed. A watercooler and a cold-water pump continuously circulates cold water through a fire sprinkler piping system. A waterheater and a hot-water pump circulates hot water through a domestic hot-water piping system. A plurality of fan-coil assemblies located throughout the building may access either the cold water flowing in the fire sprinkler piping system or the hot-water in the domestic hot-water piping system. The fan-coil assemblies include a fan and a coil. Depending upon whether hot water or cold water is flowing through the coil, air circulated by said fan may be heated or cooled for climate control.

摘要： A three-phase power transmission line phase-to-ground fault responder wherein voltage coils of respective responder relays are energized by respective phase-related voltages and wherein current coils of such relays are serially connected across the composite voltage source comprising the three serially composite voltage source comprising the respective phase-related voltages applied in series. In one embodiment the phase-related voltages are proportional to the transmission line phase voltage itself whereas in a second embodiment, less sensitive to location of fault in relation to the instrument takeoff voltage location, the phase-related voltage is the vector sum of voltages of the other two phases.
摘要翻译：一种三相电力传输线相对地故障响应器，其中各个响应继电器的电压线圈由相应的相位电压激励，并且其中这种继电器的电流线圈串联连接在复合电压源上，该复合电压源包括三个串联复合电压源包括串联施加的相应相电压。在一个实施例中，相位相关电压与传输线相位电压本身成比例，而在第二实施例中，相对于仪器起飞电压位置对故障位置的敏感度较低，相位相关电压是另外两个阶段。
