    • A system for supplying hot and cold water to an apartment/house. Recycling water from the hot into the cold water pipe comprises a faucet having adjustable first and second valves installed in the paths to hot and cold water inlets and third valve in the path to outlet. The valves are electrically controlled; circulating pump installed in the cold water pipe. When the first and second valves of at least one faucet are open and the third valve closed, activating the circulating pump will cause water from the hot water pipe to flow through the faucet to the cold water pipe; c. controller means for activating the three valves and the circulating pump in one of two modes of operation: in a first (circulation) mode, water circulation is accomplished by opening the first and second valves and closing the third valve.
    • 用于向公寓/房屋供应冷热水的系统。 将水从热水回收到冷水管中包括具有可调节的第一和第二阀的水龙头,其安装在通向出口的路径中的冷热水入口和第三阀的路径中。 阀门电气控制; 循环泵安装在冷水管中。 当至少一个龙头的第一和第二阀打开并且第三个阀关闭时,启动循环泵将使来自热水管的水流过龙头到冷水管; C。 用于以两种操作模式之一启动三个阀和循环泵的控制器装置:在第一(循环)模式中,通过打开第一和第二阀并关闭第三阀来实现水循环。

    • A method and apparatus for measuring the mass of individual objects, particularly small diamonds, within a predetermined range of sizes, by conveying the objects towards an oscillatable probe having a predetermined mass and a vacuum port of smaller dimensions than those of the objects; applying vacuum to the vacuum port to attract and hold thereto one of the individual objects to thereby add its mass to the mass of the oscillatable probe; measuring the oscillating frequency of the oscillatable probe while the individual object attracted thereto is held by the vacuum applied to the vacuum port, and utilizing the measured oscillating frequency of the probe and the object attracted thereto to compute the mass of the object, before releasing the vacuum to release the object.
    • 通过将物体朝向具有比物体尺寸小的预定质量和真空端口的可振荡探头传送,在预定尺寸范围内测量各个物体,特别是小钻石的质量的方法和装置; 对真空端口施加真空以吸引并保持其中的一个单独的物体,从而将其质量添加到可振荡探针的质量块; 测量可振动探头的振荡频率,同时被吸附到其上的单个物体由施加到真空端口的真空保持,并且利用探测器的测量振荡频率和被吸引到其上的物体来计算物体的质量, 真空释放物体。
