    Abstract: An automatic irrigation system having a simplified structure can intermittently supply water (and liquid fertilizer) required by farmer products under water saving conditions depending on the weather condition of the day independent of the size of an irrigation area. Water from a water source is pumped by a motor pump driven with electric power generated by a solar panel and stored in a storage tank. When a predetermined amount of water is stored in the tank, a water draining device continuously drains the stored water. This cycle is repeated in proportion to an amount of solar radiation incident on the solar panel. The water is then guided to the irrigation area with a tube irrigation system.

The flow control valve diverts water between the mode selector and the separate spray mode. It also allows a combination of the modes controlled by the mode selector and the separate spray mode. The shower head also includes a mode selector. The mode selector transfers or routes fluids from the flow control valve to any number of individual or a combination of flow spray mode outlets.

  • Patent number: 6702571
    Abstract: A combustion system for automatic, real-time control of a combustion process which can be applied with significant advantage to a wide range of furnaces, boilers and combustors. The system includes a burner body having a primary first fluid inlet end forming at least one primary first fluid inlet and a first fluid outlet end forming at least one first fluid outlet. An inner conduit is disposed within the burner body, forming a fluid flow region between the burner body and the inner conduit. The inner conduit has a second fluid inlet distal from the first fluid outlet and a second fluid outlet proximate the first fluid outlet. An internal adjustment device is provided for adjusting a flow cross-sectional area for a first fluid and/or a second fluid disposed within the burner body.

  • Patent number: 6557777
    Abstract: A method and system for maintaining desired water levels in a gravity flow fountain. The fountain includes manifolds that define reservoirs for storing water. The fountain is capable of generating displays by expelling variably sized and arranged water droplets, at varying rates, from the reservoirs. The expelled water must be replaced in the reservoir to continue sustained operation of the fountain. Even though the volume of water needed at each reservoir as the fountain operates is non-constant and varying, the water is controllable, and therefore, predictable. The fountain uses a programmable logic device, in combination with a variety of components, to anticipate the need for water in the reservoirs. The fountain can also use programmable logic devices, in combination with sensors and a variety of components, to historically determine the need for water in the reservoirs or meet water supply demands on a real time basis.

  • Patent number: 6554206
    Abstract: Apparatus and method for spray coating of a horizontally moving web uses a spray-down unit that sprays downwardly onto the web and a spray-up unit that sprays upwardly onto the web. Each unit has adjustable cut-offs that control the length of the spray pattern by intercepting end portions of the spray pattern. The cut-offs of each unit can be adjusted to block a spray emission opening so as to prevent the entrance of contaminants when the unit is not in operation. Fluid intercepted by the cut-offs is returned for re-use. Both units are supported on a frame, and the spray-down unit can be moved away from the spray-up unit.

  • Patent number: 6510805
    Abstract: A reforestation and nourishing practice by the use of a lighter-than-air airship system, for dispersing and planting tree saplings, primarily in remote regions which may have been devastated by fire, where access to such regions by personnel and ground equipment is difficult. The airship system comprises an aerodynamically configured structure having a semi-rigid keel or skeleton, where lift is provided by helium, with the keel mounting a liquid management mechanism consisting of a reservoir open to the outside for resupply of liquid or water, a conduit leading to a holding tank, and a piping distribution and nozzle assembly below the airship system to spray or dispense the liquid or water over selected areas to water or nourish the newly planted trees. The mechanism for temporarily storing and eventually dispensing the tree saplings is a rack mounting at least one cylindrical canister containing plural compartments.
