Abstract: An atomizer 10 atomizes a multi-component liquid from a reservoir 20 into a cloud 14 comprising small droplets 38 which are ejected into the atmosphere to a certain height and allowed to fall toward a surface 12. Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according to a predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendant drop of the liquid after a predetermined amount of the liquid has evaporated from the drop.

Abstract: A sprinkler circuit responds to the presence of water and limits watering accordingly. The sprinkler circuit comprises a control circuit and a moisture responsive circuit. The control circuit may be wired in series to a sprinkler cable at any point between a sprinkler controller (e.g., timer) and a sprinkler valve, and is powered by a valve signal sent from the sprinkler controller to the valve. The moisture responsive circuit includes two pairs of electrodes wired in series and residing at different depths. When resistance across both pairs of electrodes drops sufficiently, a relay in the control circuit opens and interrupts the valve signal to the valve.
