    摘要: An antenna protection device for insertion between sections of an antenna for cutting the passage of low-frequency alternating electric current. The device comprises a non-linear capacitor with capacitor plates connected to the antenna sections. The non-linear capacitor is characterized by a negative low-frequency voltage coefficient, whereby the passage of a high frequency alternating current remains essentially unaffected.

    摘要: 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.
