Abstract: A method of controlling an ebb and flow watering system utilizing existing hardware commonly used in ebb and flow systems including float switches, water pumps, electromechanical timers, reservoir, control bucket, flood lines, indicator LEDs and plant containers such that the filling and draining of the control bucket is improved by accommodating for hydraulic delays, flood line restrictions, and pump limitations, while further providing constant monitoring for leaks or float switch failure, and shutting off the pumps if the same are determined.

Abstract: Provided is an easy-to-use and easy-to assemble automatic refill kit for maintaining a minimum water level within a fountain. The fountain refill kit is configured to connect with a conventional water source, such as a water hose, irrigation riser, or the like, to deliver water to the fountain's trough. The refill kit includes a float which moves as the water level within the fountain rises/falls. The float is connected to a valve arm which opens or closes the valve depending on the level of the water.

Abstract: A control device is provided with a switching valve mechanism and first and second actuators. The switching valve mechanism is provided with a valve element for switching which is located within a casing. The valve element can linearly move between an open position at which first and second pressure change chambers of the casing are communicated with each other and a closed position at which the communication is interrupted. The valve element is held at the open position and the closed position by a first holding mechanism (toggle spring). When a float ascends to a first water level, the first actuator moves the valve element from the closed position to the open position. When the degree of vacuum within a pressure detection chamber becomes a second degree of vacuum or less, the second actuator moves the valve element from the open position to the closed position.

Abstract: A water-saving control device and the control method thereof is used in an inflowing waterway. The control device has an internal floating body disposed in an upper cover, a spring and a main body. The upper end of the internal floating body forms a head, which can be hermetically cooperated with an opening of the upper end of the upper cover. The side wall of the internal floating body has a water inlet. The side wall of the lower part of the main body has a flow adjusting opening and the lower part of the internal floating body is movable in the main body for adjusting the flow opening. The lower end of the spring abuts against the inside of the main body while the upper end abuts against the internal floating body to seal the opening of the upper cover.

Abstract: A system configured to distribute liquid flow into predetermined proportions is provided. The system includes a distributor defining a plurality of distributor outlets configured to deliver liquid from the distributor. A receptacle is positioned to receive liquid, the receptacle defining a plurality of receptacle outlets oriented to deliver liquid portions toward the distributor outlets. The receptacle is selfleveling such that liquid is divided by the receptacle outlets into predetermined proportions.

Abstract: A method and an apparatus for heating fluid with a gas heater and distilling fluid with the pilot light of the gas heater are disclosed. The apparatus for heating fluid and distilling fluid includes a main tank for containing fluid to be heated, a heater, adapted to have a pilot light, for heating the fluid in said main tank and an evaporator tank for vaporizing fluid received therein with heat from the pilot light. The method of heating fluid and distilling fluid includes heating a first volume of fluid with a heater having a pilot light and heating a second volume of fluid with the pilot light.

Abstract: A fuel cutoff valve comprises a casing and a float mechanism having a float and a seat portion. An upper vent hole is formed in the upper wall portion of the float, and a side portion communication hole is formed in the side wall portion. The passage area of the side portion communication hole is set so as to allow a large volume of vapors entering the float chamber to escape into the valve chamber. The passage area of the upper vent hole is set so that vapor entering the float chamber when the vehicle inclines escapes into the valve chamber, and the float chamber fills with fuel lifting the float, whereas when the vehicle turns sharply, the float is lifted without the float chamber filling with fuel.

Abstract: A crash valve is located in a liquid tight dispenser pan at a gasoline service station to close a conduit conveying gasoline to a gasoline dispensing unit to prevent uncontrolled flow of gasoline in the event a vehicle crashes into the dispensing unit. The dispenser pan collects any leaking gasoline or inflow of water; the presence of gasoline is an obvious safety hazard and the accumulating water may cause electrical or mechanical malfunction of the crash valve. An actuator, responsive to the presence of either water or gasoline in the dispenser pan, includes a weighted ball secured to a trip arm of the crash valve by a lanyard. The actuator will respond to the presence of gasoline or water by dislodging the ball and cause the ball to drop. The weight of the falling ball, translated through the lanyard, will cause the trip arm to close the crash valve and prevent further flow of gasoline therethrough and preclude the dispensing unit from pumping gasoline until the trip arm is reset.

Abstract: A self-cleaning fluid filtration system is presented and which includes a tank having a bottom wall and a side wall together forming a fluid chamber. An inlet is located in the bottom wall for receiving fluid to be filtered. A tube extends from the inlet upwardly into the chamber for directing fluid upwardly through the tube. The tube has perforations therein for directing fluid to flow outwardly therefrom. A platform is carried by the tube intermediate its ends and extends radially outward therefrom toward the side wall of the tank. A perforated rigid basket in the chamber surrounds the tube and has an open lower end mounted to the upper surface of the platform and a closed upper end located above the upper end of the tube. A collapsible fluid-permeable filter bag is located in the chamber intermediate the tube and the basket.

Abstract: Method and apparatus for sensing moisture by exposing water in a container to the atmosphere, sensing changes in the volume of the exposed water due to ambient weather conditions, controlling an electrical signal related to the sensed change and controlling the operation of an irrigation system, such as a plurality of solenoid-actuated pilot valves associated with sprinklers of the irrigation system, in response to the signal.

Abstract: A hydraulic controller is disclosed which includes a housing assembly hermetically enclosing a hydraulic fluid, conduits for transporting hydraulic fluid into and out of the housing assembly, a valve control assembly for regulating the hydraulic fluid in selected conduits and a float unit for activating the valve control assembly.
